Description
Technical Field
[0001] The utility model relates to the technical field of centrifuges, in particular to centrifuges. Background Art
[0002] The axial drum in a traditional centrifuge is an upwardly open cylinder. When the cylinder rotates at high speed, its inner wall contacts the mixture and slowly drives it to rotate. This kinetic energy transfer method is inefficient. The outer wall of the drum is provided with sieve holes for separating and screening the centrifuged mixture. However, the mesh holes are clogged due to the lack of pre-separation. In addition, the drum is fixedly installed and is not convenient to disassemble, making it troublesome to clean.

[0006] Preferably, a screw main shaft is provided in the centrifuge drum for connecting with the pre-screening spiral kit to fix the pre-screening spiral kit.
[0007] Preferably, the screw sleeve is threadedly connected to the screw main shaft, and the tightening direction of the screw sleeve relative to the screw main shaft is opposite to the rotation direction of the centrifuge drum, so that when the centrifuge drum rotates at high speed, the screw sleeve will be tightened with the screw main shaft under the action of inertia.
[0008] Preferably, the mesh diameter of the screen is larger than the mesh diameter of the liquid outlet screen hole, and the screen performs preliminary filtration on the high-speed rotating solid-liquid mixture, diverts large particles, reduces the clogging of the liquid outlet screen hole by large particles, and improves the separation purity of the liquid.
[0009] Preferably, a sealing rubber patch is fixedly provided on the side wall of the pre-screening spiral kit, and the rubber patch abuts against the inner wall of the centrifuge drum.
[0010] Preferably, a cover plate welded to the baffle plate and the upper end of the screen is fixedly provided on the top of the pre-clarification chamber to prevent the material from being directly poured into the pre-clarification chamber when being added.
