[0034] The following describes the implementation of the present invention through specific embodiments. People skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0035] See also Figures 1 to 8. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0037] The gear box body 4 rotates, and the two second bevel gears 7 are engaged with the first bevel gear 3, so that the two second bevel gears 7 rotate, and the two transmission shafts 6 rotate, and then transmit to the third bevel gear 8, each third bevel gear 8 drives the two fourth bevel gears 11 to rotate, and then drives the two circular separation bins 5 to rotate through the two rotating shafts 10. When the circular separation bin 5 rotates in the horizontal direction following the gear box body 4, the circular separation bin 5 also rotates in the vertical direction at the same time. The circular separation bin 5 rotates in the horizontal direction, so that the material in the circular separation bin 5 is centrifugally separated, and the solid particles remain in the circular separation bin 5. The liquid is thrown out of the circular separation bin 5 under the action of centrifugal force and enters the outer shell 2. The circular separation bin 5 rotates in the vertical direction, which can make the material in the circular separation bin 5 constantly flip over, and avoid the material from clogging the annular filter frame 502, making the centrifugation more sufficient.
