A solid-liquid separation centrifuge

Abstract

The invention discloses a high-efficiency solid-liquid separation centrifuge. The material to be separated is sprayed into the rotating drum along the spiral path of the flow guide mechanism, and the direction of entering the rotating drum is consistent with the turning direction of the rotating drum, so that the material to be separated enters the rotating drum. It will not disturb the flow direction of the fluid in the drum and improve the centrifugal separation efficiency of the drum. The high-speed rotating drum will throw out the liquid in the material, accumulate it through the casing and discharge it from the liquid discharge port, and at the same time trap the solid phase in the material in the On the side wall of the drum, when the centrifuge slows down, the scraper rod moves vertically, so that the scraper blades extend into the drum, and at the same time, the liquid inlet pipe stops entering the liquid, and the gas ejected by the air injection mechanism enters the rotor along the spiral path of the flow guide mechanism. In the drum, air is sprayed on the inner wall of the drum to help the scraper blade scrape the inner wall of the drum efficiently, and the scraped solid-phase materials are discharged through the discharge drum. The high-efficiency solid-liquid separation centrifuge proposed by the invention has reasonable structure and arrangement, improves centrifugal separation efficiency, and is convenient for scraping off solid materials.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to a solid-liquid separation centrifuge. Background technique [0002] The centrifuge is a machine that uses the inertial centrifugal force generated by the rotation of the drum to separate or concentrate suspensions, emulsions and other heterogeneous materials. The working principle is: when the suspension to be separated enters the drum of the centrifuge, it is The rotating drum produces strong centrifugal force to deposit the solid phase particles on the inner wall of the drum, and is trapped in the drum by the filter screen, and the liquid phase is filtered out through the filter screen. During the centrifugation process, the liquid to be separated enters directly through the liquid inlet. In the drum, it will disturb the flow direction of the liquid in the drum and affect the separation effect. At the same time, solids with high humidity after centrifugation are not easy t...

[0002] The centrifuge is a machine that uses the inertial centrifugal force generated by the rotation of the drum to separate or concentrate suspensions, emulsions and other heterogeneous materials. The working principle is: when the suspension to be separated enters the drum of the centrifuge, it is The rotating drum produces strong centrifugal force to deposit the solid phase particles on the inner wall of the drum, and is trapped in the drum by the filter screen, and the liquid phase is filtered out through the filter screen. During the centrifugation process, the liquid to be separated enters directly through the liquid inlet. In the drum, it will disturb the flow direction of the liquid in the drum and affect the separation effect

At the same time, solids with high humidity after centrifugation are not easy to scrape off when the scraper scrapes the material, reducing the amount of solid output and affecting the subsequent centrifugation effect
