Solid-liquid separation device for centrifugal machine

Abstract

The invention provides a solid-liquid separation device for a centrifugal machine. The solid-liquid separation device comprises a shell, cover plates, a filter disc and a centrifugal machine body, wherein the cover plates are buckled at the upper part of the shell, the filter disc is located in the shell and is connected with the bottoms of the cover plates, and the centrifugal machine body is located at the lower end of the shell; a liquid outlet formed in the bottom of the filter disc and a liquid inlet formed in the top of the centrifugal machine body are connected through a pipeline; the centrifugal machine body is further connected with a liquid outlet pipe, and a flow guide groove is formed in the inner wall of the liquid outlet pipe. According to the solid-liquid separation device for the centrifugal machine, by forming the flow guide groove in the inner wall of the liquid outlet pipe, a phenomenon that a liquid draining passage is blocked by separated crystals of crystallized materials is avoided; large-particle impurities such as colloids are filtered by virtue of the filter disc before a mother solution is subjected to solid-liquid separation, so that the purity of separated solids is improved.

Description

technical field [0001] The invention relates to a centrifuge solid-liquid separation device. Background technique [0002] At present, the types and structures of solid-liquid separation devices are diversified, and these solid-liquid separation devices are used in different technical fields according to different product and process requirements. Existing solid-liquid separation devices mostly use a liquid outlet pipe with an integrated structure to output liquid. However, in the actual application process, the liquid outlet pipe is often blocked due to the crystallization of the crystallized material. At this time, it is necessary to stop the machine immediately to clean the liquid outlet pipe, which reduces the production efficiency. However, how to thoroughly clean the outlet pipe of the integrated structure also makes the staff work hard.

However, in the actual application process, the liquid outlet pipe is often blocked due to the crystallization of the crystallized material. At this time, it is necessary to stop the machine immediately to clean the liquid outlet pipe, which reduces the production efficiency.

However, how to thoroughly clean the outlet pipe of the integrated structure also makes the staff work hard

[0003] Furthermore, some mother liquors to be treated often contain large volumes of colloids, particles, and sundries. When the centrifuge is working, some lighter impurities are easily thrown out, resulting in blockage of the outlet pipe, while some heavier Heavy impurities are mixed in the solids that need to be collected, such as copper powder, industrial grade monoammonium phosphate, etc., reducing the purity of solids
