Detailed Description

With reference to fig. 1 and 2, the integrated sewage treatment device comprises a tank body 1, wherein a front-end treatment tank 5, a reaction tank 6, a clean water tank 7 and an operation room 8 are arranged in the tank body, a water inlet 2 is arranged on one side of the tank body, a filter mechanism 3 is arranged at the water inlet, the filter mechanism comprises a grid 31, a trash discharge port 201 is formed in the water inlet, the trash discharge port is located on the side of the grid, a valve plate 202 is arranged at the trash discharge port, the valve plate is connected with a connecting rod mechanism, and the connecting rod mechanism is connected with the bottom of the grid; the top of the grid is in movable fit with the guide structure 32; the connecting rod mechanism is manually pushed and drives the bottom of the grating to move towards the impurity discharging port, and synchronously, the connecting rod mechanism drives the valve plate to open the impurity discharging port.

Sewage enters the tank body 1 through the water inlet 2, and particles are blocked by the grating 31 and accumulated in the water inlet 2 and are positioned at the bottom position of the grating, as shown in fig. 2, the particles have the tendency of being displaced towards the grating as the sewage flows towards the grating. When the cleaning is needed, an operator pushes the connecting rod mechanism, the bottom of the grating is displaced towards the impurity discharging port, and the displacement direction is opposite to the flowing direction of the sewage in the water inlet. The grate 31 pushes the accumulated particles towards the reject port 201, through which they leave the water inlet, as shown in fig. 3. A collection container may be placed below the trash opening 201 to collect the particulate matter falling from the trash opening. After the cleaning of the particles is completed, the operator pulls the link mechanism, the link mechanism pulls the grating 31 to reset, and simultaneously, the valve plate 202 is pulled to reset, and the valve plate closes the impurity discharging port 201. The sewage can normally enter the tank 1 through the water inlet 2.

As shown in fig. 2, the link mechanism includes a main rod 33 and an auxiliary rod 34, the bottom of the grid 31 is hinged with the main rod, the auxiliary rod is hinged with the main rod, and the auxiliary rod is hinged with the valve plate 202; when the valve plate closes the impurity discharging port 201 from bottom to top, the end of the auxiliary rod hinged with the valve plate is in a declined state. When the operator opens the impurity discharging port again, the auxiliary rod can smoothly push the valve plate. When the auxiliary rod pushes the valve plate, the main rod 33 pushes the grating 31 which is originally inclined to be inclined more, and the top of the grating descends along the guide structure 32.
