The inner wall of the base 2 is slidably connected with a recovery bin 3, so that the recovery bin 3 can be taken out or placed along the inner wall of the base 2. The recovery bin 3 can store the dried and filtered silicon carbide powder. After the recovery bin 3 is full, it can be taken out by pulling it outward. The top of the drying chamber 1 is fixedly connected with a motor 7, so that the drying chamber 1 provides a support and fixing effect for the motor 7. The staff starts the motor 7, so that the motor 7 drives the agitator 9 to rotate. The inner wall of the drying chamber 1 is fixedly connected with a heater 8, so that the drying chamber 1 provides a support and fixing effect for the heater 8. The heater 8 can be heated to dry Dry silicon carbide powder, and the heater 8 is a prior art, which has the effect of controlling the temperature, and will not be described in detail here. The top of the drying chamber 1 is penetrated and fixedly connected with a feed hopper 4, so that the drying chamber 1 provides a support and fixing effect for the feed hopper 4, and the silicon carbide powder can be added from the feed hopper 4. The feed hopper 4 is provided with an automatic closing mechanism, and the automatic closing mechanism includes a cylinder 13, and the outer wall of the cylinder 13 is fixedly connected to the inner wall of the feed hopper 4, so that the feed hopper 4 provides a fixing effect for the cylinder 13, and the outer wall of the cylinder 13 is rotatably connected with a flip plate 10, so that the flip plate 10 can be rotated along the cylinder 13 The outer wall rotates, and when the flip plate 10 is in a vertical state, the feed hopper 4 is in an open state. When the upper and lower sides of the flip plate 10 are in contact with the feed hopper 4, the feed hopper 4 can be closed. The inner wall of the flip plate 10 is slidably connected with a block 16, so that the block 16 can move along a fixed direction on the inner wall of the flip plate 10, and the block 16 can drive the flip plate 10 to rotate. The outer wall of the block 16 is hinged with a sliding column 15, so that when the sliding column 15 moves, it can drive the block 16 to move along the inner wall of the flip plate 10, so that the structure at the hinge can operate smoothly, and the outer wall of the sliding column 15 is sleeved with a spring A17.

[0032] Reference Figure 1 , Figure 3The outer wall of the feed hopper 4 is fixedly connected to a fixed column 19, so that the feed hopper 4 provides a supporting and fixing effect for the fixed column 19. One end of the fixed column 19 is rotatably connected to a counterweight 18, so that the counterweight 18 can rotate along one end of the fixed column 19. The rotation of the counterweight 18 can limit the movement of the sliding column 15. The bottom of the counterweight 18 is magnetically connected to a magnetic block 20, so that the magnetic block 20 can absorb the counterweight 18, so that the counterweight 18 can be fixed without deviation. The outer wall of the L-shaped member 14 is connected to the feed hopper 4. The inner wall of the hopper 4 is slidably connected, so that the L-shaped member 14 can move vertically along the inner wall of the feed hopper 4. The outer wall of the L-shaped member 14 contacts the outer wall of the flip plate 10, so that the L-shaped member 14 and the flip plate 10 are completely fitted, so that the sealing effect of the feed hopper 4 is better. The outer wall of the flip plate 10 is slidably connected to the inner wall of the feed hopper 4, so that the flip plate 10 can close the feed hopper 4. One end of the sliding column 15 is elastically connected to the inner wall of the feed hopper 4 through the spring A17, and one end of the spring A17 is connected to the feed hopper 4. The inner wall of the hopper 4 is fixedly connected, and the other end of the spring A17 is fixedly connected to the outer wall of the sliding column 15. When not affected by external force, the spring A17 provides a leftward force for the sliding column 15, so that the sliding column 15 drives the flip plate 10 to rotate to close the feed hopper 4. The bottom of the L-shaped part 14 is elastically connected to the inner wall of the feed hopper 4 through the spring B21, so that the L-shaped part 14 can be elastically reset after being squeezed downward. A group of L-shaped parts 14 are respectively provided at the upper and lower ends of the feed hopper 4. The L-shaped part 14 is made of elastic rubber material, which can better fit the flip plate 10 to completely close the feed hopper 4. One end of the spring B21 is fixedly connected to the inner wall of the feed hopper 4, so that the feed hopper 4 provides a supporting and fixing effect for the spring B21. Two groups of springs B21 are respectively provided at the upper and lower ends of the feed hopper 4, and the other end of the spring B21 is fixedly connected to the bottom of the L-shaped part 14. The elastic force of the spring B21 drives the L-shaped part 14 to move up and down to better fit the flip plate 10.

[0033] Reference Figure 2-Figure 4The bottom of the drying chamber 1 is fixedly connected with a discharge pipe 11, and the discharge pipe 11 is provided with a valve. After the silicon carbide micropowder is dried, the discharge pipe 11 can be opened to flow out. The bottom of the discharge pipe 11 is fixedly connected to the top of the base 2, so that the silicon carbide micropowder can flow from the drying chamber 1 to the recovery bin 3 inside the base 2 through the discharge pipe 11. The output shaft of the motor 7 is fixedly connected with the stirrer 9, so that the stirrer 9 can be driven to work when the motor 7 is started. The top of the stirrer 9 is fixedly connected with a square rod 12, so that the square rod 12 can be driven when the stirrer 9 rotates. The square rod 12 performs circular motion, and can contact the automatic closing mechanism when it moves. One end of the magnetic block 20 is fixedly connected to the outer wall of the feed hopper 4, so that the feed hopper 4 provides a supporting and fixing effect for the magnetic block 20. One end of the square rod 12 contacts the bottom of the counterweight 18, so that the square rod 12 contacts the counterweight 18 when it moves, and the counterweight 18 rotates to release the restriction on the sliding column 15. The inner wall of the feed hopper 4 penetrates and is slidably connected to the outer wall of the sliding column 15, so that the sliding column 15 can move left and right along a fixed direction to ensure that the position is not offset.

[0034] Working principle: the staff first adds the wet silicon carbide powder from the open feed hopper 4. After the silicon carbide powder enters the drying chamber 1, the output shaft of the motor 7 is started to drive the agitator 9 to start stirring. At the same time, the square rod 12 above the agitator 9 will be driven to rotate, thereby contacting the counterweight 18, so that the counterweight 18 is separated from the attraction of the magnetic block 20 and rotates along one end of the fixed column 19. At this time, the restriction of the counterweight 18 on the sliding column 15 is released, and the sliding column 15 moves to the left through the elastic force of the spring A17, and at the same time drives the block 16 to slide on the inner wall of the flip plate 10, and drives the flip plate 10 to rotate on the outer wall of the cylinder 13 to close the feed hopper 4. When the staff finishes adding the silicon carbide powder and starts the motor 7 to start stirring, the feed hopper 4 can be automatically closed to prevent the silicon carbide powder from emanating outward during the stirring and drying process and being inhaled by the staff to affect their health.

[0035] When the flip plate 10 rotates to the right position, it will contact the L-shaped part 14. The L-shaped part 14 will completely fit the flip plate 10 and the feed hopper 4 through the elastic force of the spring B21. At this time, the feed hopper 4 can be completely closed to further prevent the silicon carbide powder from dispersing.

[0036] After the feed hopper 4 is closed, the heater 8 is turned on to start heating and drying the silicon carbide micropowder. After drying, the silicon carbide micropowder can enter the base 2 by opening the discharge pipe 11, and is filtered and screened by the screen 5 to leave unqualified silicon carbide micropowder, and the rest will pass through the screen 5 into the recovery bin 3 to complete the drying and recovery of the silicon carbide micropowder.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
