A liquid outlet gap 10 is formed between the liquid inlet pipe 7 and the upper part of the centrifugal cavity, and the liquid outlet gap 10 is communicated with the upper cavity 4 and the inner cavity 9 of the centrifugal tank 6. In the centrifugal chamber, the treated liquid and the impurities of the solids are supposed to be separated, wherein the impurities of the solids are blocked by the centrifugal assembly 11 and can be retained in the centrifugal chamber, and the liquid flows back upwards and re-enters the upper chamber 4, and the impurities in the upper chamber 4 can be made less clean through the circulation treatment.
A centrifugal component 11 is arranged in the inner cavity 9 of the centrifugal tank 6, the centrifugal component 11 can drive liquid in the inner cavity 9 to centrifugally rotate, the liquid and filter residues are separated, and the separated liquid upwards enters the upper cavity 4 from the liquid outlet gap 10. Specifically, as shown in fig. 2, the centrifugal assembly 11 includes a lower rotating disc 111, an upper rotating disc 112, and a plurality of discs 114, wherein the lower rotating disc 111 is supported by a rotating shaft 16, so that active rotation can be realized, and the rotating shaft 16 is used for inputting rotation power of the centrifugal assembly 11; the upper rotating disc 112 is fixedly connected to the upper part of the lower rotating disc 111 through a connecting frame 113, and the outer circumference of the upper rotating disc 112 is movably connected to the inner circumferential wall of the centrifugal tank 6, so that the centrifugal assembly 11 also forms a rotating supporting position at the upper end to keep the rotating action of the centrifugal assembly 11 stable.

A gap is formed between the adjacent discs 114 for passing liquid, and during rotation of the discs, the solid-liquid mixture in the centrifugal cavity moves outwards under the action of centrifugal force, and during movement of the solid particles, the solid particles are guided by the discs to have downward inclined stress, so that relatively heavy solid substances in the solid-liquid mixture can be retained in the centrifugal cavity, and separated filtrate is re-output from the liquid outlet gap 10 at the upper end of the centrifugal tank 6 and flows back to the upper chamber 4, thereby realizing separation between solid and liquid.

The rotating shaft 16 can extend downwards out of the tank body 1 and is connected with a rotary driver through a transmission mechanism 17, so that the centrifugal assembly 11 can be driven.

The communication port 12 adopts a structure capable of being opened and closed, specifically, a sealing sleeve 14 is sleeved on the periphery of the centrifugal tank 6, and the position of the sealing sleeve 14 corresponds to the position of the lower chamber 5. The seal cartridge 14 is driven by a first lifter 15, and is slidably adjustable up and down along the outer periphery of the centrifugal tank 6. When the sealing sleeve 14 moves to the periphery of the communication port 12, the sealing sleeve 14 can seal the communication port 12, so that the inner cavity 9 of the centrifugal tank 6 and the lower cavity 5 are mutually disconnected, centrifugal movement of liquid in the centrifugal tank 6 cannot influence the lower cavity 5 outside the centrifugal tank 6, and excessive rotation stirring of the solid-liquid mixture in the lower cavity 5 is avoided.
A sealing disc 13 is installed in the lower chamber 5, and the sealing disc 13 is driven to lift by a first lifting rod 15. The shape position of the sealing disc 13 is mutually matched with the filter screen 3 on the partition board 2, when the lifting rod 15 drives the sealing disc 13 to move upwards, the sealing piece on the upper side of the sealing disc 13 can mutually prop against the lower side face of the partition board 2, the area covered by the filter screen 3 is sealed through the sealing disc 13, the partition board 2 can be in a closed structure up and down, and the upper cavity 4 and the lower cavity 5 are mutually isolated.
Further, the sealing disc 13 and the sealing sleeve 14 can be fixedly connected with each other to form an integrated structure, and the sealing disc and the sealing sleeve can realize synchronous lifting action in the lifting adjustment process. Specifically, the inner periphery of the sealing disc 13 is fixedly connected with the upper part of the outer periphery of the sealing sleeve 14, and the sealing disc 13 and the sealing sleeve 14 are lifted and lowered synchronously. The upper end of the lifting rod I15 is fixedly connected with the lower part of the sealing disc 13, and can drive the sealing disc 13 and the lifting rod I to lift.
When the sealing disk 13 is moved to the upper end position, the sealing disk 13 closes the filter screen 3 at the partition plate 2, and at the same time the sealing sleeve 14 is moved to a relatively high position, and the communication port 12 is opened with the outer periphery of the centrifugal tank 6, at this time the communication port 12 is in an open state. At this time, the inner cavity 9 of the centrifugal tank 6 is communicated with the lower chamber 5, and an integral body can be formed between the centrifugal cavity and the lower chamber 5, so that the separated impurities can enter the lower chamber 5 from the centrifugal cavity.
