[0055] A discharge shell 4 is provided on one side of the lower shell 2 , and a suction pump 5 is fixed on the top of the discharge shell 4 , through which the discharge shell 4 is pumped out.

[0056] Example 1:

[0057] When it is necessary to dry the external water glass sand, the used water glass sand is introduced into the feed port 22 through the feed shell 3, and then falls onto the filter screen 9. The linear drive is controlled to drive the filter screen 9 to swing up and down on the connecting sleeve 23. The control drive motor 10 is started, thereby driving the connecting shaft 25 to rotate, and then driving the filter screen 9 to rotate on the limit ring 33. In this way, the filter screen 9 is controlled to swing and rotate at the same time, which is convenient for dispersing the water glass sand on the filter screen 9 and improving the drying efficiency.

[0058] The heater 8 is started to transfer heat to the inside of the support frame 7, so as to dry the water glass sand on the filter screen 9. When the filter screen 9 swings up and down and rotates, the water glass 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, the external blower is started to blow air into the upper shell 1, so that hot air flows in the upper shell 1, thereby improving the drying efficiency.

[0060] During drying, the temperature sensor 28 monitors the temperature between each two groups of filters 9 in real time and transmits the temperature to the controller, which sets the maximum temperature range to When it is identified that the temperature inside the upper shell 1 reaches the set temperature range, the heater 8 is stopped and the filter 9 is continued to be controlled to swing and rotate, continuously driving the water glass sand to rotate on the filter 9, and falling through the upper filter 9 to the lower filter 9 until it falls on the sieve plate 13. In the process, each layer of filter 9 will dry the water glass sand retained on its surface, further improving the drying efficiency.

[0061] The humidity of the water glass sand falling on the sieve plate 13 is monitored by a humidity detector. When the humidity does not meet the standard, all the pump bodies 31 on the recovery pipe 29 are controlled to open, and the valve 2 34 on the recovery pipe 29 is controlled to open, and the water glass sand that is not completely dried on the sieve plate 13 is recovered to the top filter screen 9 through the recovery pipe 29 for secondary drying.

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

[0063] When the dried water glass sand falls into the lower shell 2, the pressure sensor monitors the weight on the sieve plate 13 in real time. When the water glass sand falls, the pressure sensor monitors that the weight on the sieve plate 13 is equal to When the brush plate 19 enters the screening slot 14, the motor 1 is controlled to rotate back and forth at a certain angle, so that the brush plate 19 swings back and forth in the screening slot 14, thereby unblocking the blocked screening slot 14.

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

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

[0066] Embodiment 2;

[0067] In this embodiment, based on the first embodiment, when the water glass sand that is not completely dried on the sieve plate 13 is returned to the uppermost filter screen 9, it is necessary to determine the temperature in the upper shell 1 and make further adjustments;

[0068] Specifically, when the water glass sand is recovered, the temperature of the different layers of filter screen 9 is monitored in real time by the temperature sensor 28. When the undried water glass sand on the sieve plate 13 is sucked to a temperature of On the filter 9 within the range of;

[0069] The steps of pumping are: opening valve 2 34 at the bottom of the recovery pipe 29, and opening the corresponding temperature at The valve 32 on the branch pipe 30 in the range is opened at the same time, and the pump body 31 along the way is opened to recover the water glass sand on the sieve plate 13 to a temperature between On the filter screen 9 within the range, further drying.

[0070] The above steps can save energy while performing secondary drying, without the need for additional heat supply, and avoid slight cracks in the water glass sand caused by excessive high temperature.

[0071] Further, when less than half of the temperature monitored by the temperature sensor 28 is When the temperature is low, it means that the temperature is not enough to dry the water glass sand. At this time, the water glass sand on the sieve plate 13 is recovered to the uppermost filter screen 9 and the heater 8 is turned on to continue heating the upper shell 1. At the same time, the blower is turned on to blow the hot air evenly in the upper shell 1 to increase the temperature in the upper shell 1 and ensure the drying quality.

[0072] When the temperature in the upper shell 1 is raised again, the temperature sensors 28 of each layer monitor the temperature of the layer in real time. When the temperature is raised, the temperature of one group or two adjacent groups of temperature sensors 28 does not reach When it is within the range, it means that the upper filter 9 at the position where the temperature sensor 28 is located is blocked by water glass sand, which makes it difficult for hot air to circulate to the lower filter 9. Start the controller and control the telescopic cylinder 36 at the corresponding position to extend, so that the brush plate 237 contacts the lower surface of the blocked filter 9. At this time, the linear drive control filter 9 is paused to swing up and down, so that the filter 9 contacts the brush plate 237. Continue to control the drive motor 10 to drive the connecting shaft 25 to rotate. Since the bearing sleeve 21 is connected to the connecting shaft 25 bearing, the bearing sleeve 21 will not rotate, and the connecting shaft 25 drives the filter 9 to rotate. When the filter 9 rotates, the brush plate 237 contacts it, and all the blockages in the filter 9 can be removed.

[0073] Through the above steps, the filter screen 9 is prevented from being blocked, which affects the circulation of hot air and thus affects the drying efficiency.
