the data processing unit 3 receives multiple monitoring data of the discharge temperature measuring point 22 at each fixed-frequency monitoring time point, determines the current temperature of the gypsum board powder in a weighted average mode by taking the multiple monitoring data as a group, compares the current temperature of the gypsum board powder with the monitoring temperature of the air outlet temperature measuring point 24 closest to the current time point, and regulates and controls the flux of the temperature control butterfly valve 46 and the on-off state of the second electromagnetic valve 16 based on the comparison result.

The temperature is reduced when the gypsum board powder contacts with the arc-shaped cooling pipe 44, and the temperature homogenization is realized by the stirring of the gypsum board powder in the heat exchange cooling cavity 11, but because the discharge temperature measuring point 22 is used for randomly monitoring the gypsum board powder on the discharge port 14, when the temperature of the gypsum board powder is not uniform, the difference between the temperature data monitored twice is large, and the problem of inaccurate temperature monitoring of the gypsum board powder is caused.

In order to solve the above-mentioned temperature, the discharge temperature measuring point 22 of the present embodiment is triggered multiple times at each fixed-frequency monitoring time point to obtain multiple monitoring data, and the current temperature of the gypsum board powder is determined by taking the multiple monitoring data as a group and by means of weighted average, for example, the monitored temperatures of the discharge temperature measuring point 22 are respectively 30 ℃, 25 ℃, 35 ℃, 28 ℃ and 32 ℃, so that the current temperature of the gypsum board powder monitored by the discharge temperature measuring point 22 at the fixed-frequency monitoring time point is: 30+25+35+28+ 32/5-29.4 c, is more accurate and closer to real data than if the temperature monitored at each time was directly taken as the current temperature of the gypsum board powder.

The specific implementation steps of the data processing unit 3 for regulating and controlling the flux of the temperature control butterfly valve 46 and the on-off state of the second electromagnetic valve 16 based on the comparison result are as follows:

when the monitored temperature of the air-out temperature measuring point 24 closest to the current time point is far greater than the discharge temperature T of the gypsum board powder, for example, when the monitored temperature of the air-out temperature measuring point 24 closest to the current time point-the discharge temperature T of the gypsum board powder is greater than or equal to 20 ℃, the maximum flux of the temperature control butterfly valve 46 is maintained and the normally closed state of the second electromagnetic valve 16 is maintained.

When the monitored temperature of the air-out temperature measuring point 24 closest to the current time point is greater than the discharge temperature T of the gypsum board powder, for example, 20 > the monitored temperature of the air-out temperature measuring point 24 closest to the current time point-the discharge temperature T of the gypsum board powder is greater than 8 ℃, and the monitored temperature of the air-out temperature measuring point 24 closest to the current time point is in the threshold range, the flux of the temperature control butterfly valve 46 is gradually reduced, and the normally closed state of the second electromagnetic valve 16 is maintained.

It should be particularly noted that the arc-shaped cooling pipe 44 and the gypsum board powder are cooled by heat exchange, so that the air in the arc-shaped cooling pipe 44 is heated while the gypsum board powder is cooled, and finally the temperature averaging is achieved, for example, 10 ℃ cold air is introduced into 150 ℃ gypsum board powder, in an ideal case, after heat exchange, the temperature of the gypsum board powder is reduced to 80 ℃ and the temperature of the air in the arc-shaped cooling pipe 44 is raised to 80 ℃, so that the monitored temperature of the outlet air temperature measuring point 24 closest to the current time point can roughly represent the temperature of the gypsum board powder, and the temperature data difference detected by the outlet air temperature measuring point 22 is relatively large due to the non-uniform temperature of the powder, for example, ± 2 ℃, so that in the early stage of cooling, the temperature of the gypsum board powder is represented by the monitored temperature of the outlet air temperature measuring point 24 closest to the current time point, compared with the method that the temperature of the gypsum board powder is directly detected by the discharge temperature measuring point 22, the method is more accurate, so that the arc-shaped cooling pipe 44 is divided into a plurality of graded cooling pipes in the embodiment, and the air temperature monitored by the air outlet temperature measuring point 24 is closer to the real temperature of the gypsum board powder.

When the current temperature of the gypsum board powder monitored by the discharge temperature measuring point 22 is equal to the discharge temperature T of the gypsum board powder, the flux of the temperature control butterfly valve 46 is closed and the rotation state of the heat exchange cooling cavity 11 is kept, and the regulation opening state of the second electromagnetic valve 16 is regulated and controlled when the monitoring data of the discharge temperature measuring point 22 is stable.

When the current temperature of the gypsum board powder monitored by the discharge temperature measuring point 22 is equal to the discharge temperature T of the gypsum board powder, the data processing unit 3 regulates and controls the air exhaust assembly to work so as to exhaust all the gas in the arc-shaped cooling pipe 44, the rotation state of the heat exchange cooling cavity 11 is kept, the data processing unit 3 continues to receive the monitoring data of the discharge temperature measuring point 22, and when the difference between the monitoring data is stable, the heat exchange cooling cavity 11 is regulated and controlled to rotate until the discharge port 14 faces downwards, and the regulation and control opening state of the second electromagnetic valve 16 is regulated and controlled so as to realize discharging after aging.

In the later stage of cooling, because the gypsum board powder is uniformly stirred for a plurality of times in the heat exchange cooling cavity 11, the temperature of the gypsum board powder tends to be stable, the difference value between a plurality of times of monitoring data of the gypsum board powder by the discharge temperature measuring point 22 tends to 0, and at the moment, the current temperature of the gypsum board powder monitored by the discharge temperature measuring point 22 represents the real temperature of the gypsum board powder.

Consequently this embodiment is through increasing the air flow rate in the arc cooling tube 44, improve the homogeneity of air temperature in the pipeline, and the air temperature in the arc cooling tube 44 is similar to the current actual temperature of gypsum board powder, thereby the temperature of gypsum board powder is judged at the cooling initial stage to the convenience, and then realize the even cooling work to the gypsum board powder, and then improve the temperature monitoring accuracy to the gypsum board powder, and improve cooling efficiency, the true temperature of gypsum board powder is confirmed in the cooling later stage to the convenience, the temperature accuracy nature when guaranteeing the ejection of compact of gypsum board powder, make things convenient for the normal work of later stage gypsum board production line.

In addition, as shown in fig. 4, the invention also provides a control method of the powder aging system of the gypsum board production line, which comprises the following steps:

step 100, pouring a certain amount of gypsum board powder into the heat exchange cooling cavity, and introducing cold air for cooling;

step 200, monitoring the temperature of the gypsum board powder regularly, taking the average value of multiple monitoring data in each fixed-frequency monitoring time point as the current temperature of the gypsum board, calculating the temperature difference between the air outlet temperature of the cold air and the current temperature of the gypsum board powder, and regulating and controlling the inlet flow of the cold air according to the comparison result;

step 300, comparing the current temperature of the gypsum board powder with a set discharge temperature, closing the flow of introduced cold air according to the comparison result, pumping out the cold air, and keeping the rotation action of the heat exchange cooling cavity;

and step 400, when the multiple monitoring temperatures of the gypsum board powder are the same, rotating the heat exchange cooling cavity until the discharge port faces downwards, and discharging the gypsum board powder after cooling and aging from the discharge port.

This embodiment is through increasing cooling pipeline in the storage cavity of gypsum board powder, in order to cool down the gypsum board powder to demand temperature, and through dividing cooling pipeline into the multistage, so that the inside temperature of cooling pipeline is even, thereby increase the cooling time of gypsum board powder, improve the cooling homogeneity of gypsum board powder, and the terminal air-out temperature of cooling pipeline is close the current temperature of gypsum board powder this moment, thereby can roughly judge the current temperature of gypsum board powder according to cooling pipeline's air-out temperature, and the regulation and control is to the cooling efficiency of gypsum board powder, it is average through the control temperature weighting to the gypsum board powder, can directly acquire the true temperature of gypsum board powder, carry out ejection of compact operation based on the true temperature of gypsum board powder.
