Through the setting of the limit rings 14, the support net 11 and the noise reduction shell 2 are in a state of active connection, and the inner wall of one end of the support net 11 is fixed with a gear ring 13, and the end of the noise reduction shell 2 close to the gear ring 13 is fixedly connected with a flushing motor 3, and the output shaft of the flushing motor 3 is located in the inner cavity of the noise reduction shell 2. The end of the output shaft of the flushing motor 3 is fixed with a gear 19 through a reducer, and the gear 19 is meshed with the gear ring 13. By setting the flushing motor 3, the rotation of the flushing motor 3 can drive the gear 19 fixedly connected thereto to rotate, and the gear 19 can drive the support net 11 to rotate through the gear ring 13 meshing therewith.
[0026] The outer surface of the solid interception net 12 is evenly fixedly connected with springs 15 and buffer blocks 16, and two adjacent springs 15 are in a staggered state. The other end of the spring 15 and the other end of the buffer block 16 are fixedly connected to the inner wall of the support net 11. Through the arrangement of the spring 15 and the buffer block 16, the resilience of the spring 15 and the buffer block 16 can buffer the vibration generated by the solid interception net 12, reduce the impact of the solid interception net 12 on the noise reduction housing 2, and thus make the dehydrator stable when in use. The material of the buffer block 16 can be rubber, and through the arrangement of the buffer block 16, it is convenient for the support net 11 to drive the solid interception net 12 to rotate.
[0027] A recoil pipe 5 is provided in the middle of the top of the noise reduction shell 2, and a water inlet pipe 6 is provided at one end of the recoil pipe 5. An electric ball valve 7 is provided at one end of the water inlet pipe 6. When the electric ball valve 7 is in an open state, water for flushing the solid interception net 12 can enter the inner cavity of the recoil pipe 5 through the water inlet pipe 6. The water in the inner cavity of the recoil pipe 5 can be sprayed onto the solid interception net 12 through a nozzle provided at the bottom of the inner cavity, thereby realizing backwashing of the solid interception net 12, avoiding clogging of the solid interception net 12, and facilitating solid-liquid separation of the solid interception net 12.
[0028] It can be seen from the above description that the buffer structure, when in use, can intercept solid materials in the material, thereby improving the solid-liquid separation effect of the dehydrator.
[0029] A rotating rod 21 is movably connected in the inner cavity of the buffer structure, and the outer surface of the rotating rod 21 is wrapped with a buffer ring. The rotating rod 21 is in contact with the solid interception net 12 through the buffer ring. The buffer ring can be made of rubber. The end of the rotating rod 21 passes through the noise reduction shell 2 and extends to the outside of the noise reduction shell 2, and the rotating rod 21 and the noise reduction shell 2 are in a state of active connection. A servo motor 10 is fixedly connected to one end of the noise reduction shell 2, and the end of the output shaft of the servo motor 10 is connected to the end of the rotating rod 21 through a synchronous structure. In some embodiments of the present application, the synchronous structure may include a synchronous wheel 1 fixedly connected to the end of the output shaft of the servo motor 10, a synchronous wheel 2 fixedly connected to one end of the rotating rod 21, and a synchronous belt. The synchronous wheel 1 and the synchronous wheel 2 are connected through a synchronous belt transmission. Through the setting of the servo motor 10, the rotation of the servo motor 10 can drive the rotating rod 21 to rotate.
[0030] The outer ring of the rotating rod 21 is fixedly connected with a spiral push blade 18, and the spiral push blade 18 contacts the inner wall of the solid interception net 12. Through the setting of the spiral push blade 18, the rotation of the rotating rod 21 can drive the spiral push blade 18 to rotate. During the rotation process, the spiral push blade 18 can push the material intercepted by the solid interception net 12 to move.
[0031] A feed chamber is provided at the other end of the rotating rod 21, and a throwing port 20 is provided on the side wall of the feed chamber at one end close to the servo motor 10, and a feed port 4 is provided at the other end of the feed chamber. Through the setting of the feed chamber, the material to be separated into solid and liquid can enter the feed chamber through the feed port 4, and the material in the feed chamber can be directly thrown onto the solid interception net 12 through the throwing port 20. The solid interception net 12 can intercept the solid matter in the material, and the liquid component in the material passes through the solid interception net 12 and enters between the solid interception net 12 and the support net 11. When the sound generated by the material being thrown on the solid interception net 12 is propagated in the liquid material between the support net 11 and the solid interception net 12, the sound is diffused in the liquid material, reducing the vibration intensity of the sound, so that the propagated sound is reduced, thereby achieving the noise reduction function.
[0032] A solid discharge pipe 17 is fixed to one end of the buffer structure near the feed port 4, and a connecting pipe 9 adapted to the solid discharge pipe 17 is provided at one end of the noise reduction shell 2 near the feed port 4. The end of the solid discharge pipe 17 away from the connecting pipe 9 is flush with the inner wall of the solid interception net 12, and the other end of the solid discharge pipe 17 is in contact with the inner wall of the noise reduction shell 2, and the outer surface of the solid discharge pipe 17 is wrapped with a buffer pad. Through the arrangement of the solid discharge pipe 17 and the connecting pipe 9, when the solid discharge pipe 17 and the connecting pipe 9 overlap, the solid matter intercepted by the solid interception net 12 can be discharged through the solid discharge pipe 17 and the connecting pipe 9, and when the buffer structure rotates, the solid discharge pipe 17 can rotate accordingly. When the solid discharge pipe 17 is staggered with the connecting pipe 9, the object matter intercepted in the buffer structure cannot be discharged, which can avoid the separated liquid matter from being contaminated. A liquid discharge pipe 8 is provided at the other end of the noise reduction shell 2, and the separated liquid matter can be discharged through the liquid discharge pipe 8.
[0033] The outer surface of the noise reduction shell 2 is wrapped with sound-absorbing cotton, which can absorb the noise generated when the dehydrator is working, play a noise reduction function, and facilitate the use of the dehydrator.
[0034] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods.

The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.
[0035] To sum up: when the sedimentation centrifugal dehydrator is in use, the servo motor 10 works, and the servo motor 10 drives the rotating rod 21 connected thereto to rotate. During the rotation of the rotating rod 21, the material to be separated into solid and liquid enters the feed chamber through the feed port 4. Under the action of centrifugal force, the material in the feed chamber is thrown onto the solid interception net 12 through the throwing port 20. The solid interception net 12 intercepts the solid matter in the material, and the liquid matter in the material can pass through the solid interception net 12 and be discharged through the liquid discharge pipe 8. During the rotation of the rotating rod 21, the spiral pusher blade 18 is driven to rotate, and the spiral pusher blade 18 pushes the solid material adhered to the inner wall of the solid interception net 12 and the sedimented solid material to move, so that the solid material can be discharged through the solid discharge pipe 17 and the connecting pipe 9. During the use of the dehydrator, the vibration generated by the material being thrown on the solid interception net 12 is reduced by the spring 15 and the buffer block 16, so that the noise reduction shell 2 can remain stable, which is convenient for the use of the sedimentation centrifugal dehydrator, and the liquid material and sound-absorbing cotton outside the solid interception net 12 can reduce the noise generated by the material being thrown on the solid interception net 12, which is convenient for the use of the dehydrator.
