[0024] In this embodiment, an accommodation chamber is formed inside the clamping base 12. A fixed column 19 is fixedly installed on the bottom inner wall of the accommodation chamber. A transmission gear 20 is rotatably sleeved on the fixed column 19. A plurality of sliders 22 are slidably installed on the bottom inner wall of the accommodation chamber. Transmission racks 21 are fixedly installed on one sides of the plurality of sliders 22. The plurality of transmission racks 21 are all engaged with the same transmission gear 20. The transmission gear 20 can be driven to rotate by the transmission rack 21 fixedly installed on the slider 22 provided with a threaded hole among the plurality of transmission racks 21, and the rotation of the transmission gear 20 drives the remaining transmission racks 21 to move.

[0025] In this embodiment, a plurality of limit clamps 17 are slidably installed on the top of the clamping base 12. Helical racks 18 are fixedly installed on the bottoms of the plurality of limit clamps 17. Helical tooth grooves are formed on the tops of the plurality of sliders 22.

[0027] Working principle: When producing ethyl methylpiperonylglycidate, the staff buckles the sealing cover 4. Multiple buckle metal blocks 6 fixedly installed on the outer side of the sealing cover 4 drive the corresponding triangular buckles 7 to slide into the corresponding limit slots. Subsequently, the multiple triangular buckles 7 come into contact with the corresponding two buckle clips 10. The staff presses down the sealing cover 4 forcefully to drive the multiple triangular buckles 7 to press down into the gaps between the corresponding two buckle clips 10. Then, multiple support springs 11 assist the corresponding buckle clips 10 to reset and limit the corresponding triangular buckles 7, completing the buckling of the sealing cover 4. The staff starts the centrifugal servo motor 13 through the control panel 2. The centrifugal servo motor 13 starts to drive the clamping base 12 to rotate. The rotation of the clamping base 12 drives the mesh inner barrel 16 and the filter screen 15 to rotate. The staff pours the raw materials through the feeding head 5. Through the centrifugal force generated by the rotation, the moisture in the raw materials is stripped, and the moisture is discharged through the water outlet head 14. When the production is completed, the staff stops the machine. After it completely stops, the sealing cover 4 is opened. The transmission servo motor 25 is started through the control panel 2. The transmission servo motor 25 starts to drive the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the corresponding slider 22 to move. The movement of the slider 22 drives the transmission rack 21 to move. The movement of the transmission rack 21 drives the transmission gear 20 to rotate and drives the remaining transmission racks 21 to move. The movement of the remaining transmission racks 21 drives the corresponding sliders 22 to move. The tops of the multiple sliders 22 are all provided with helical tooth grooves, and the multiple helical tooth grooves are respectively adapted to the corresponding helical racks 18. The movement of the multiple sliders 22 presses the corresponding helical racks 18 with the helical tooth grooves on them. Since the helical racks 18 are adapted to the corresponding helical tooth grooves, the movement of the sliders 22 with the helical tooth grooves on them can drive the corresponding helical racks 18 to move back and forth. The movement of the multiple helical racks 18 drives the corresponding limit clips 17 to move away from each other, releasing the limit on the mesh inner barrel 16. The staff can take out the mesh inner barrel 16 to collect the finished products and clean the mesh inner barrel 16.

[0028] The technical progress obtained by the present utility model compared with the prior art is that the mesh inner barrel 16 and the filter screen 15 can be disassembled, which is convenient and fast for cleaning, and it is also more convenient to collect the materials therein, reducing waste, increasing the practicability of the device, and the sealing cover 4 can be buckled through a buckle mechanism, eliminating the need for the staff to buckle it multiple times, which is convenient and fast.
