A filter cylinder 7 is provided on the support circular plate 2 through a rotating mechanism. A heating mechanism is provided on one side of the shell 1 above the support circular plate 2. A shielding mechanism is provided next to the heating mechanism. The design of the drain hole 3 allows the liquid thrown out of the filter cylinder 7 to flow to the discharge pipe 19 through the drain hole 3.

[0023] The rotating mechanism includes a support shaft 4. The support shaft 4 is rotatably mounted on the middle of the support circular plate 2 via a bearing. The lower end of the support shaft 4 is located below the support circular plate 2 and is fixedly connected to the output end of the top of the first servo motor 5. The outer wall of the first servo motor 5 is fixed to the bottom of the support circular plate 2 via a mounting plate. The upper end of the support shaft 4 is located above the support circular plate 2 and is fixedly connected to the center of the bottom of the sleeve 6. The top of the inner side of the sleeve 6 is threadedly connected to the top of the outer side of the filter cylinder 7, and the bottom of the inner side of the sleeve 6 is in close contact with the bottom of the outer side of the filter cylinder 7, so that the sleeve 6 and the filter cylinder 7 can be disassembled and installed, allowing the trifluoromethylbenzonitrile inside the filter cylinder 7 to be removed after centrifugation. The top of the outer side of the sleeve 6 is rotatably connected to the top inside the housing 1 via a bearing, which increases the stability of the rotation of the sleeve 6.

[0024] The sleeve 6 has a through groove on its side wall, and the through groove is distributed at an equal angle with respect to the central axis of the sleeve 6, so that the liquid thrown out from inside the filter cylinder 7 can enter the outside of the sleeve 6 through the through groove. The filter cylinder 7 has filter holes evenly arranged below the through groove on its outer side, so that the liquid in trifluoromethylbenzonitrile can be discharged through the filter holes, and the solid trifluoromethylbenzonitrile can remain inside the filter cylinder 7.

[0025] A fixing rod 8 is fixed to the top of the filter cylinder 7, which facilitates access to the interior of the filter cylinder 7.

[0026] The heating mechanism includes an inner hollow pipe 9, which is fixed inside the shell 1. The length of the inner hollow pipe 9 is equal to the length of the through groove, and the highest point of the inner hollow pipe 9 is at the same height as the highest point of the through groove, and the lowest point of the inner hollow pipe 9 is at the same height as the lowest point of the through groove. A jet nozzle 10 is provided on one side of the inner hollow pipe 9 near the sleeve 6, and the jet nozzle 10 is interconnected with the inner hollow pipe 9. The jet nozzles 10 are evenly distributed on the inner hollow pipe 9. The middle of the other side of the inner hollow pipe 9... An air outlet pipe 11 is provided, and the air outlet pipe 11 is connected to the inner hollow pipe 9. The end of the air outlet pipe 11 passes through the side wall of the housing 1 and is connected to the air outlet end of the hot air blower 12. The air inlet end of the hot air blower 12 is provided with an air inlet pipe 13, and the outer wall of the hot air blower 12 is fixed to the outer wall of the housing 1 by a mounting plate. This ensures that when the filter cartridge 7 rotates, the hot air sprayed from the nozzle 10 can dry the side of the filter cartridge 7 over a large area, thereby improving the drying efficiency of the fluoromethylbenzonitrile inside the filter cartridge 7.

[0027] The sleeve 6 is equipped with a dust filter to prevent external dust from entering the equipment.

[0028] The shielding mechanism includes a vertical shaft 14. The vertical shaft 14 is rotatably mounted on the top of the housing 1 via a bearing. A shielding plate 15 is fixed inside the housing 1 on the outer wall of the lower end of the vertical shaft 14. The shielding plate 15 is designed with an arc-shaped structure. The air nozzle 10 is located inside the shielding plate 15. The upper end of the vertical shaft 14 is fixedly connected to the output end of the bottom of the second servo motor 16. The outer wall of the second servo motor 16 is fixed to the top of the housing 1 via a mounting plate. This ensures that the liquid thrown out from inside the filter cartridge 7 will not enter the interior of the air nozzle 10, preventing blockage of the air nozzle 10 and the inner hollow tube 9, and also preventing liquid from entering the interior of the hot air blower 12, which could damage the hot air blower 12.

[0029] The handheld controller is connected to the first servo motor 5, the second servo motor 16, and the hot air blower 12 via radio signals.

[0030] Working principle: When using the trifluoromethylbenzonitrile centrifugal drying equipment, first remove the top cover 18 from the feed pipe 17, then pour trifluoromethylbenzonitrile liquid into the filter cylinder 7, and then reinstall the top cover 18 on the feed pipe 17. Then, start the first servo motor 5 through the handheld controller. The first servo motor 5 drives the sleeve 6 and the filter cylinder 7 to rotate through the support shaft 4. The liquid inside the filter cylinder 7 is thrown out through the filter hole on the filter cylinder 7. The liquid enters the bottom of the shell 1 through the drain hole 3. The liquid is discharged through the discharge pipe 19. The thrown liquid will not enter the inside of the jet nozzle 10 under the protection of the baffle plate 15.

[0031] When it is necessary to dry the trifluoromethylbenzonitrile inside the filter cartridge 7, the second servo motor 16 is started by the handheld controller to drive the vertical shaft 14 and the baffle plate 15 to rotate 180 degrees clockwise, so that the jet nozzle 10 is removed from the baffle. Then, the hot air blower 12 is started by the handheld controller. The hot air generated by the hot air blower 12 is sprayed onto the rotating filter cartridge 7 through several jet nozzles 10, thereby completing the drying of the trifluoromethylbenzonitrile inside the filter cartridge 7. The steam is discharged through the discharge pipe 19, thus combining the centrifugation and drying of trifluoromethylbenzonitrile, improving the processing efficiency of trifluoromethylbenzonitrile.

[0032] Remove the top cover 18 from the feed pipe 17, and rotate the filter cylinder 7 through the fixing rod 8 so that the filter cylinder 7 is removed from the inside of the sleeve 6. Then pour out the dried trifluoromethyl benzonitrile inside the sleeve 6.
