Please refer to fig. 1, which is a schematic structural diagram of a granular dry ice conveying apparatus according to an embodiment of the present invention.

The granulated dry ice conveying apparatus 10 of an embodiment includes a pelletizer dry ice machine 100 and a seal conveying assembly 200. The pelletizing ice dryer 100 is used to make pelletized dry ice. The seal-transfer assembly 200 includes a seal box 210. referring also to fig. 2, the seal-transfer assembly 200 further includes a conveyor belt 220 and a plurality of dry ice trays 230. The input port of the seal box 210 is in communication with the output port of the ice pelletizer 100. The conveyor belt 220 and the plurality of dry ice baffles 230 are arranged in the sealed box 210, and the conveyor belt 220 is used for conveying the granular dry ice. The plurality of dry ice baffles 230 are connected with the conveyor belt 220, and an ice storage space 232 is formed between two adjacent dry ice baffles 230. The ice storage space 232 is used to receive the granulated dry ice.

In this embodiment, the seal box 210 is sleeved on the conveyor belt 220, the seal box 210 isolates the conveyor belt 220 from the external environment, so that the entry of water vapor in the external environment is reduced, the water vapor content in the seal box 210 is reduced, the probability that ice cubes are formed in the vicinity of the conveyor belt 220 due to condensation is reduced, the probability that the conveyor belt 220 is stuck by the ice cubes is effectively reduced, and the transmission resistance of the conveyor belt 220 is effectively reduced. The side baffles for preventing the granular dry ice from falling off are arranged on the two sides of the conveying belt, and the ice blocks formed between the conveying belt and the side baffles on the two sides are mainly reduced in the embodiment, so that the probability that the conveying belt is blocked by the ice blocks formed between the side baffles and the conveying belt by condensation is reduced. Moreover, in another embodiment, when the inner walls of the enclosure act as side dams, ice formation between the conveyor belt and the enclosure is reduced, thereby reducing the chance of the conveyor belt being blocked by ice that condenses and forms between the enclosure and the conveyor belt.

In one embodiment, referring to fig. 1, the seal box 210 is provided with an air outlet 212, and the air outlet 212 is used for ensuring the uniform internal pressure of the seal box 210. In this embodiment, the air outlets 212 are disposed close to the granulating dry ice machine 100, the number and the aperture of the air outlets 212 are small, for example, one air outlet 212 is disposed on the seal box 210, and the aperture of the air outlet 212 is 1 to 2 mm. Under the arrangement of the air outlet holes 212, the air outlet holes 212 communicate the inside of the seal box 210 with the external environment, and under the condition that the number and the aperture of the air outlet holes 212 are small, the contact area between the seal box 210 and the external air is small, so that the difficulty of external water vapor entering the seal box 210 is increased. In addition, when the conveyor belt 220 transports the granular dry ice, the air outlet 212 ensures that the internal air pressure of the sealed box 210 is consistent with the external atmospheric pressure, so that the air pressure in the sealed box 210 is consistent and kept at the atmospheric pressure, thereby effectively avoiding the situation that the internal pressure of the sealed box 210 is overlarge during transportation, namely, the situation that the pressure of the sealed box 210 is suppressed, ensuring the normal transportation of the conveyor belt 220 in the sealed box 210, and further ensuring the normal transportation of the granular dry ice.

In another embodiment, the material of the conveyor belt 220 includes polyoxymethylene resin, the conveyor belt 220 carries granular dry ice, and the granular dry ice is solid carbon dioxide, which has the effect of low-temperature condensation, i.e. the function of condensing water vapor on the surface of the conveyor belt 220 to form ice cubes, thereby easily causing the conveyor belt 220 to be adhered to itself. In order to solve the above problems, the material of the conveyor belt 220 is made of an anti-freezing polyoxymethylene resin, so that the probability of the granular dry ice adhered to the surface of the conveyor belt 220 is reduced, and the adhesion of the granular dry ice on the conveyor belt 220 is effectively reduced. Further, the conveyor belt 220 having the polyoxymethylene resin also has a slip-preventing function, so that a coefficient of static friction between the conveyor belt 220 and the granulated dry ice increases, thereby increasing a static friction force between the conveyor belt 220 and the granulated dry ice. Thus, when the conveyor belt 220 is disposed obliquely, for example, the height of the output port of the granulating ice dryer 100 is smaller than the height of the feed port of the tabletting machine, the conveyor belt 220 needs to be in an upward tilting state from the start end to the end of the conveying, and the conveyor belt 220 made of materials including polyoxymethylene resin is used, so that the slip probability of the granular dry ice on the conveyor belt 220 is effectively reduced, and the anti-slip effect is achieved. For other materials with anti-skid and anti-freezing effects, the materials can be used as the materials of the conveyor belt, and the details are not repeated here.

In one embodiment, referring to fig. 2, a plurality of dry ice baffles 230 are sequentially distributed on the conveyor belt 220 along the conveying direction of the conveyor belt 220. In this embodiment, the dry ice shutter 230 is configured to contact the granular dry ice, and the dry ice shutter 230 blocks the granular dry ice on the conveyor belt 220, that is, an ice storage space 232 formed between two adjacent dry ice shutters 230 is configured to store the granular dry ice, and the granular dry ice is stably placed on the conveyor belt 220. In addition, the dry ice shutter 230 partitions each ice storage space 232, effectively reduces the sliding of the granular dry ice in the ice storage space 232, and has the effect of blocking the sliding of the granular dry ice. In addition, the plurality of dry ice baffles 230 are sequentially distributed along the conveying direction of the conveyor belt 220, that is, the distribution path of the plurality of dry ice baffles 230 is parallel to the conveyor belt 220, so that the plurality of dry ice baffles 230 are orderly distributed, the number and the volume of the granular dry ice are conveniently distributed correspondingly, and the internal space volume of each ice storage space 232 is matched with the number and the volume of the granular dry ice.

Further, the distance between two adjacent dry ice baffles 230 is equal. In this embodiment, the dry ice shutter 230 is configured to contact the granular dry ice, and the dry ice shutter 230 blocks the granular dry ice on the conveyor belt 220, that is, an ice storage space 232 formed between two adjacent dry ice shutters 230 is configured to store the granular dry ice, and the granular dry ice is stably placed on the conveyor belt 220. In addition, the dry ice shutter 230 partitions each ice storage space 232, effectively reduces the sliding of the granular dry ice in the ice storage space 232, and has the effect of blocking the sliding of the granular dry ice. In addition, the distances between two adjacent dry ice baffles 230 are equal, that is, the conveyor belt 220 is equally divided by the distribution path of the plurality of dry ice baffles 230, so that the spaces between two adjacent dry ice baffles 230 are equal, the space volume of each ice storage space 232 is equal, the number of the granular dry ice in each ice storage space 232 is basically consistent, the same volume of the granular dry ice is conveniently conveyed, the weight of the granular dry ice at each position on the conveyor belt 220 is equal, and the normal operation of the conveyor belt 220 is ensured.

In one embodiment, the conveyor belt is provided with a resistance-increasing groove, and the opening of the resistance-increasing groove faces the dry ice baffle. In this embodiment, the resistance-increasing grooves are formed in the conveyor belt, and the resistance-increasing grooves are formed in the surface of the conveyor belt, that is, the resistance-increasing grooves are formed in the surface of the conveyor belt, which bears the granular dry ice. When the granular dry ice is conveyed, the conveying belt drives the granular dry ice, wherein the granular dry ice is driven to move through static friction force between the granular dry ice and the conveying belt, and the resistance increasing groove conducts roughening treatment on the surface of the conveying belt, so that the surface of the conveying belt is uneven, the static friction factor of the surface of the conveying belt is increased, the static friction force between the conveying belt and the granular dry ice is increased, and the anti-skid performance of the conveying belt is further improved.

In one embodiment, the seal box has a visualization window for displaying the conveyor belt within the seal box. In this embodiment, the seal box is used for right the conveyer belt carries out sealed parcel, has reduced the invasion of outside vapor effectively, for the convenience right the running state of conveyer belt monitors add on the seal box visual window, through visual window is convenient for see through the seal box is right the conveyer belt monitors. In another embodiment, the material of the sealed box comprises polyvinyl chloride, so that the box body of the sealed box has a transparent effect, and the material of the sealed box is arranged, so that the internal condition of the sealed box can be monitored, namely, the transmission condition between the conveyor belt and the granular dry ice is observed through the box body of the sealed box. Other materials with transparent or semitransparent effects can be used as the material for the sealing box, and are not described herein again.

In one embodiment, referring to fig. 1, the seal box 210 includes a first seal box 214, a second seal box 216, and a turning seal box 218, the first seal box 214 is communicated with the pellet dryer 100, the first seal box 214 is further connected with the second seal box 216 through the turning seal box 218, an inclined included angle is formed between the first seal box 214 and the second seal box 216, referring to fig. 3, the seal transmission assembly 200 further includes a turning rotating shaft 240, the turning seal box 218 is provided with a turning hole 2182, the turning rotating shaft 240 is rotatably disposed in the turning hole 2182, the turning rotating shaft 240 is used for connecting with an output shaft of a turning motor, and the turning rotating shaft 240 abuts against the conveyor belt 220 to adjust a transmission direction of the conveyor belt 220. In this embodiment, an included angle is formed between the first seal box 214 and the second seal box 216, the start end to the end of the first seal box 214 is tilted upward, the start end to the end of the second seal box 216 is sunk downward, and the first seal box 214 and the second seal box 216 realize steering at the steering seal box 218, so that the conveying direction of the conveyor belt 220 is changed in the steering seal box 218. In addition, in order to facilitate the adjustment of the conveying direction of the conveyor belt 220, the turning rotating shaft 240 is additionally arranged on the turning seal box 218, and the turning rotating shaft 240 is in sliding contact with the conveyor belt, that is, the turning rotating shaft 240 serves as a turning rotating shaft of the conveying direction of the conveyor belt 220, so that the conveying direction of the conveyor belt 220 is turned in the turning seal box 218. In this way, under the steering of the steering seal box 218, the conveying path of the conveyor belt 220 is increased, so that the conveying stroke of the granular dry ice is increased, and the conveying time of the granular dry ice is increased, thereby effectively avoiding the situation that the volume of the granular dry ice entering the tabletting machine is too large, namely, the situation that the granular dry ice in the feed port of the tabletting machine is too much to cause overflow is avoided.

It is understood that, during the transportation of the conveyor belt 220, the ice storage space 232 stores therein the granulated dry ice, and when the sealing box 210 is tilted, that is, the conveyor belt 220 has a tilted posture, the dry ice blocking plate 230 is used for blocking the extrusion of the granulated dry ice so as to reduce the sliding tendency of the granulated dry ice on the conveyor belt 220. However, when the amount of the granular dry ice in the ice storage space 232 is too large, the pressing force applied to the dry ice baffle 230 will be increased sharply, and the dry ice baffle 230 is rigidly connected to the conveyor belt 220, so that once the weight of the granular dry ice pressed to the dry ice baffle 230 is too heavy, the dry ice baffle 230 and the conveyor belt 220 are easily broken, and the granular dry ice in each ice storage space 232 cannot be blocked, and further, the other subsequent dry ice baffles 230 are impacted by the accumulated granular dry ice, so that the plurality of dry ice baffles 230 are broken, and the granular dry ice conveying device cannot convey the granular dry ice into the feed port of the tablet press.

In order to solve the above problem, that is, to reduce the breakage probability between the dry ice shutter 230 and the conveyor belt 220, please refer to fig. 4, the sealing and conveying assembly 200 further includes a memory torsion spring 250, the memory torsion spring 250 is located at the connection position between the dry ice shutter 230 and the conveyor belt 220, one end of the memory torsion spring 250 is connected to the dry ice shutter 230, the other end of the memory torsion spring 250 is connected to the conveyor belt 220, and the memory torsion spring 250 is used for buffering the deflection between the dry ice shutter 230 and the conveyor belt 220. In this embodiment, the memory torsion spring 250 connects the dry ice shutter 230 with the conveyor belt 220, that is, the dry ice shutter 230 is connected with the conveyor belt 220 through the memory torsion spring 250. The memory torsion spring 250 is connected to the dry ice shutter 230 and the conveyor belt 220, respectively, so that the dry ice shutter 230 has a deflecting effect on the conveyor belt 220, that is, the dry ice shutter 230 rotates around the center line of the memory torsion spring 250. Moreover, the two ends of the memory torsion spring 250 are connected by a coil spring, when one end of the memory torsion spring 250 deflects, an elastic force resisting the above-mentioned deflection tendency is generated on the memory torsion spring 250, for example, when the end of the memory torsion spring 250 connected with the dry ice baffle 230 deflects, that is, the dry ice baffle 230 rotates on the conveyor belt 220, that is, the dry ice baffle 230 is deflected due to an excessively large extrusion force from the granular dry ice, the other end of the memory torsion spring 250 is fixed on the conveyor belt, so that the elastic force of the memory torsion spring 250 on the dry ice baffle 230 is increased, thereby the memory spring generates a slow acting force to the deflection direction of the dry ice baffle 230, further the deflection amplitude of the dry ice baffle 230 is reduced, and the condition that the deflection angle of the dry ice baffle 230 is excessively large is effectively avoided, thereby effectively reducing the probability of the dry ice baffle 230 breaking from the conveyor belt 220 and ensuring the normal transportation of the granular dry ice by the granular dry ice transportation device. In addition, the memory spring has deformation range memory ability, promptly the material of memory spring includes memory metal, is convenient for under the appointed temperature, can resume to the original condition fast in the short time. Thus, after the granular dry ice in the ice storage space 232 is transferred to the feed port of the tablet press, the dry ice baffle 230 corresponding to the ice storage space 232 can be quickly restored to the state perpendicular to the conveyor belt 220, that is, the memory spring is restored to the initial state, so that the problem that the ice storage space 232 is shielded due to the fact that the dry ice baffle 230 is not restored to the original state for a long time is avoided, and the situation that the quantity of the granular dry ice in the ice storage space 232 is reduced is avoided. In addition, in order to further reduce the breakage probability between the dry ice baffle 230 and the conveyor belt 220, the number of the memory springs is two, the two memory springs are arranged oppositely, and the two memory springs are respectively arranged on two side surfaces of the dry ice baffle 230.

Further, although the dry ice baffle 230 can reduce the probability of breakage from the conveyor belt 220 under the action of the elastic force provided by the memory spring, since the conveyor belt 220 is inclined during transportation, the inclination of the dry ice baffle 230 is more severe under the extrusion of the granular dry ice, that is, the inclined plane of the dry ice baffle 230 is close to the horizontal plane, which easily causes the granular dry ice to fall from the previous ice storage space 232 to the next ice storage space 232, thereby easily causing the weight of the granular dry ice on the next dry ice baffle 230 to increase, and further easily causing the excessive deflection due to the overlarge extrusion force borne by the subsequent dry ice baffle 230, so that most of the granular dry ice slides downwards, and the transportation of the granular dry ice cannot be effectively performed. In order to solve the above-mentioned problem, that is, to ensure that the granular dry ice in each ice storage space 232 is stably placed therein, referring to fig. 4, the dry ice barrier 230 includes a plate body 234 and a barrier outer edge 236, the plate body 234 is connected to the conveyor belt 220 through the pressing spring, the barrier outer edge 236 is located at an end of the plate body 234 away from the conveyor belt 220, the barrier outer edge 236 has an arc-shaped barrier surface 2362, a distance between the arc-shaped barrier surface 2362 and the memory spring is gradually increased in a direction away from the conveyor belt 220, and the arc-shaped barrier surface 2362 is used for blocking movement of the granular dry ice. In this embodiment, during the transportation of the granulated dry ice, a majority of the granulated dry ice is carried on the plate body 234. When the quantity and volume of the granular dry ice are too large, the arc-shaped blocking surface 2362 blocks the granular dry ice to be separated from the plate body 234, and the distance between the arc-shaped blocking surface 2362 and the memory spring is gradually increased along the direction away from the conveyor belt 220 by means of the arc-shaped structure of the arc-shaped blocking surface 2362, so that the arc-shaped blocking surface 2362 has a bent structure towards the direction of the conveyor belt 220, the granular dry ice which is possibly separated from the plate body 234 is blocked, the probability of the granular dry ice being separated from the dry ice blocking plate 230 is effectively reduced, and the placement stability of the granular dry ice in the ice storage space 232 is ensured.

In another embodiment, since the sealed box 210 has two sealed boxes 210 with different inclined postures, namely the first sealed box 214 and the second sealed box 216, so that the conveyor belt has two different conveying directions, in order to cope with the situation that the granular dry ice may slide after the conveying direction is changed, namely, the granular dry ice in the ice storage space 232 moves from the dry ice baffle 230 on one side to the dry ice baffle 230 on the other side, at this time, the contact surface between the dry ice baffle 230 and the granular dry ice is changed, and blocking of the granular dry ice on both sides of the dry ice baffle 230 is required, in this embodiment, the baffle outer edge portion 236 has two arc-shaped blocking surfaces 2362 which are arranged oppositely, and the bending directions of the two arc-shaped blocking surfaces 2362 are opposite to each other, so as to facilitate blocking of the granular dry ice after the conveying direction is changed.

The granulating dry ice machine is used for making granular dry ice. The sealed conveying assembly comprises a sealed box, a conveying belt and a plurality of dry ice baffles. And the input port of the seal box is communicated with the output end of the granulating and ice drying machine. The conveyer belt and a plurality of the dry ice baffle all set up in the seal box, the conveyer belt is used for transmitting the granular dry ice.
