Description

technical field [0001] The invention relates to a small ultra-high-speed horizontal screw centrifuge, which belongs to the technical field of solid-liquid separation equipment. Background technique [0002] A centrifuge is a separation device that uses the centrifugal force generated by the drum to drive the material to rotate to strengthen the separation process. Centrifugal separation is the process of separating heterogeneous mixtures such as liquid-solid, liquid-liquid-solid, liquid-liquid, etc. by centrifugal force. The process is divided into three forms: centrifugal filtration, centrifugal separation and centrifugal sedimentation, and the corresponding centrifuges are also divided into three categories: filter centrifuge, centrifugal separator and sedimentation centrifuge. The purpose of separation is nothing more than: recovery of valuable solid phase; recovery of valuable liquid phase; recovery of both solid and liquid phases; discharge of both solid and liquid pha...

AI Technical Summary

Problems solved by technology

[0004] At present, the solid-liquid separation devices for fine particle solutions are as follows: (1) disc separator: it can automatically feed and discharge slag, but the slag discharge device is complicated and has not been realized on small machines for the time being, and can only handle solid For materials with an amount of less than 10%, the processed materials contain a lot of liquid and are usually used for concentration

(2) Tubular centrifuge: automatic slag discharge cannot be realized, and materials with a solid content of less than 5% are usually processed for clarification

Due to the limitations of the structure and components such as the differential, it cannot be miniaturized, and the separation factor is also low
