[0036] It should be noted that the present invention is a centrifugal device for preparing molluscicide ethanolamine salt. When the user starts to centrifuge the preparation of molluscicide ethanolamine salt, by conveying materials into the drum 23, the third motor 52 is operated, thereby driving the transmission rod 51 to rotate, and the gear 53 is rotated. The gear 53 and the straight tooth plate 54 are meshed with each other, so that the straight tooth plate 54 moves toward the rear end, thereby driving the transport plate 4 to move toward the rear end, so that one end of the transport plate 4 inside the drum 23 no longer contacts the inner side wall of the drum 23.

The first motor 2 is used to drive the centrifugal shaft 21 to rotate, and the connecting boss 22 is used to rotate, thereby driving the drum 23 to start high-speed rotation. Under the strong centrifugal force generated by the high-speed rotation of the solid-liquid mixture containing molluscicide amine ethanolamine salt in the drum 23, the solid particles will be thrown to the inner wall of the drum 23 due to their large density, forming a The filter cake layer is formed. At the same time, under the strong centrifugal force generated by high-speed rotation, the liquid will pass through the filter port 24 on the side wall of the drum 23 due to the small centrifugal force, enter the cavity of the protective shell 3, and be discharged into the three-way connecting pipe 16 from the leakage port 31, thereby entering the water collection tank 14, collecting the residual solvent, and entering the next device through the drain pipe 15.

Through double protection, the leakage of molluscicide ethanolamine salt is prevented, which may cause harm to the health of the operators and the environment. At the same time, the drum 23 is buffered by three groups of linearly arranged buffer mechanisms arranged on the inner side wall of the protective shell 3. When the drum 23 rotates, multiple groups of rollers 36 move along the outer wall of the drum 23. Rotation, the springs 32 at the top of the two groups of support columns 34 buffer the high-speed rotating drum 23 to prevent uneven material loading or problems with the equipment itself from causing unbalanced operation and causing strong vibration. When the centrifugal process reaches the set time or the required separation effect, the first motor 2 reduces the power to make the drum 23 rotate slowly, and the second motor 47 is operated to drive the rotating rod 46 to rotate, thereby driving the scraper 45 to rotate, so that the top of the scraper 45 no longer contacts the top of the protective plate 44, and at the same time, the top of the scraper 45 is in close contact with the inner wall of the drum 23, and the filter cake layer formed on the inner side of the drum 23 is scraped off to the upper end of the conveyor belt 43 by the scraper 45, and the material filter cake is transmitted to the outside through the conveyor belt 43 to complete a working cycle.
