[0054] A first brush plate 19 is fixed at the bottom of the rotating roller 15. A through groove 18 is formed through the middle of the rotating roller 15. By starting the first motor to drive the rotation of one of the fixed shafts 20, the rotation of the rotating roller 15 can be driven through the cooperation of the transmission wheel 16 and the belt 17, so that the through groove 18 corresponds to the screening groove 14, facilitating the falling of the sodium silicate sand on the sieve plate 13 into the lower shell 2.

[0055] A discharge shell 4 is arranged on one side of the lower shell 2. A suction pump 5 is fixed on the top of the discharge shell 4. The discharge shell 4 is pumped out through the suction pump 5.

[0056] Example 1:

[0057] When it is necessary to dry the external sodium silicate sand, the used sodium silicate sand is introduced into the feeding port 22 through the feeding shell 3, and then falls onto the filter screen 9. Control the linear drive to drive the filter screen 9 to swing up and down on the connecting sleeve 23. Control the driving motor 10 to start, so as to drive the connecting shaft 25 to rotate, and then drive the filter screen 9 to rotate on the limiting ring 33, so as to control the filter screen 9 to swing and rotate at the same time, which is convenient for dispersing the sodium silicate sand on the filter screen 9 and improving the drying efficiency.

[0058] Start the heater 8 to transfer heat to the inside of the support frame 7, which is convenient for drying the sodium silicate sand on the filter screen 9. When the filter screen 9 swings up and down and rotates, the sodium silicate sand on the upper filter screen 9 will fall onto the lower filter screen 9.

[0059] When the filter screen 9 swings up and down, start the external blower to blow the air flow into the upper shell 1, so that the hot air flows in the upper shell 1, improving the drying efficiency.

[0060] During drying, the temperature sensor 28 monitors the temperature between every two groups of filter screens 9 in real time and transmits the temperature to the controller. The set range of the highest temperature in the controller is , when it is recognized that the temperature inside the upper shell 1 reaches the set temperature range, suspend the operation of the heater 8, continue to control the filter screen 9 to swing and rotate, continuously drive the sodium silicate sand to rotate on the filter screen 9, and pass through the upper filter screen 9 to fall onto the lower filter screen 9 until it falls on the sieve plate 13. During this process, each layer of filter screen 9 will dry the sodium silicate sand remaining on its surface, further improving the drying efficiency.

[0061] Monitor the humidity of the sodium silicate sand falling on the sieve plate 13 through the humidity detector. When the humidity does not meet the standard, control all the pump bodies 31 on the recovery pipe 29 to open, and control the second valve 34 on the recovery pipe 29 to open, and recover the sodium silicate sand that has not been completely dried on the sieve plate 13 to the uppermost filter screen 9 through the recovery pipe 29 for secondary drying.

[0062] When the dried sodium silicate sand is qualified, it is necessary to transfer the sodium silicate sand out. Since the rotating roller 15 under the sieve plate 13 is in the initial state, the top of the rotating roller 15 abuts against the screening groove 14. The maximum weight that the sieve plate 13 can bear is set as G in the controller. When the real-time monitored weight is equal to G, the controller controls the first motor to start, so that the through groove 18 on the rotating roller 15 corresponds to the screening groove 14, connecting the lower shell 2 and the upper shell 1, and the dried sodium silicate sand on the sieve plate 13 passes through the screening groove 14 and the through groove 18 and then falls into the lower shell 2.

[0063] When the dried sodium silicate sand falls into the lower housing 2, the pressure sensor monitors the weight on the sieve plate 13 in real time. When the sodium silicate sand is falling, if the pressure sensor monitors that the weight on the sieve plate 13 is equal to it indicates that the screening groove 14 is blocked. The controller transmits a signal to the first motor to continue driving the rotating roller 15 to rotate, so that the first brush plate 19 corresponds to the screening groove 14. When the first brush plate 19 enters the screening groove 14, control the first motor to rotate back and forth and swing by a certain angle, so that the first brush plate 19 swings back and forth in the screening groove 14, facilitating the dredging of the blocked screening groove 14.

[0064] It should be added that the connection between the first brush plate 19 and the rotating roller 15 is set in an arc shape, which can enable the first brush plate 19 to smoothly enter the screening groove 14.

[0065] After dredging for a period of time, continue to control the through groove 18 on the rotating roller 15 to be docked with the screening groove 14, continue to screen the sodium silicate sand into the lower housing 2, and then start the suction pump 5 to pass the dried sodium silicate sand in the lower housing 2 through the discharge housing 4.

[0066] Embodiment 2;

[0067] In this embodiment, based on Embodiment 1, when the sodium silicate sand that is not completely dried on the sieve plate 13 is returned to the topmost filter screen 9, it is necessary to determine the temperature inside the upper housing 1 and make further adjustments;

[0068] Specifically, when recycling the sodium silicate sand, the temperature sensors 28 monitor the temperatures of different layers of the filter screen 9 in real time. When more than half of the temperatures monitored by the temperature sensors 28 are only the sodium silicate sand that is not dried on the sieve plate 13 needs to be sucked onto the filter screen 9 within the range of the temperature;

[0069] The suction steps are as follows: Open the second valve 34 at the bottom of the recovery pipe 29, and open the first valve 32 on the branch pipe 30 corresponding to the temperature within the range of At the same time, turn on the pump body 31 along the way to recycle the sodium silicate sand on the sieve plate 13 onto the filter screen 9 within the range of the temperature for further drying.

[0070] Through the above steps, energy conservation can be achieved during secondary drying, without the need to provide additional heat, and it can avoid the generation of slight cracks in the sodium silicate sand due to excessive high temperature.

[0071] Furthermore, when less than half of the temperatures monitored by the temperature sensors 28 are When it indicates that the temperature is insufficient to dry the sodium silicate sand, at this time, the sodium silicate sand on the sieve plate 13 is recycled to the topmost filter screen 9 while the heater 8 is turned on, and the upper shell 1 is continuously heated. At the same time, the blower is turned on to evenly disperse the hot air in the upper shell 1, increasing the temperature in the upper shell 1 to ensure the drying quality.

[0072] When heating the upper shell 1 again, the temperature sensors 28 of each layer all monitor the temperature of this layer in real time. When heating up, if the temperature of one group or two adjacent groups of temperature sensors 28 does not reach within the range, it indicates that the filter screen 9 on the upper layer of the position where the temperature sensor 28 is located is blocked by sodium silicate sand, resulting in difficulty for hot air to flow to the lower filter screen 9. The controller is started to control the telescopic cylinder 36 at the corresponding position to extend, making the second brush plate 37 contact with the lower surface of the blocked filter screen 9. At this time, the linear drive to control the up and down swing of the filter screen 9 is paused to facilitate the contact between the filter screen 9 and the second brush plate 37. Then, the drive motor 10 is continuously controlled to drive the connecting shaft 25 to rotate. Since the bearing sleeve 21 is connected to the connecting shaft 25 by bearings, the bearing sleeve 21 will not rotate, while the connecting shaft 25 drives the filter screen 9 to rotate. While the filter screen 9 is rotating, the second brush plate 37 contacts it, and all the blocked parts of the filter screen 9 can be removed.

[0073] Through the above steps, the blockage of the filter screen 9 is avoided, which affects the flow of hot air and thus affects the drying efficiency.
