[0023] Please see Figure 1-4 The present invention provides an embodiment of a centrifuge for preventing residue, comprising a centrifuge base 1, a centrifuge body 2, a sealing cover 7, and a drive box 11. A drive shaft 16 for transmission is installed at the bottom of the centrifuge body 2. A filter cartridge 17 is installed in the centrifuge body 2. A groove 22 adapted to the drive shaft 16 is formed at the bottom of the filter cartridge 17. A sinkhole 21 is formed at the top of the filter cartridge 17. Side scrapers 20 are fixed on both sides of the filter cartridge 17. An inner cylinder 18 is placed in the filter cartridge 17.

A first sealing ring 5 is connected to the top of the lower sealing block 3. An upper sealing block 9 is fixed at the bottom of the sealing cover 7. A second sealing ring 10 is fixed at the bottom of the upper sealing block 9.

[0024] The side scrapers 20 are symmetrically distributed about the central axis of the filter cartridge 17, and the front-to-back distance of the side scrapers 20 closer to the filter cartridge 17 is greater than the front-to-back distance of the side farther away from the filter cartridge 17.

[0025] The hanging rings 19 are symmetrically distributed about the central axis of the inner tube 18, and the top of the inner tube 18 is fixed with an edge plate.

[0026] The recessed trough 21 has a concave design, and the edge plate at the top of the inner cylinder 18 is accommodated in the recessed trough 21.

[0027] The side of the sealing cover 7 is fitted with an adapter shaft 6 for flipping, and the front end face of the sealing cover 7 is fixed with a reinforcing rib 8.
