Liquid separation structure used for tubular centrifuging machine

Abstract

The invention belongs to the technical field of solid-liquid separation equipment application and particularly discloses a liquid separation structure used for a tubular centrifuging machine. The liquid separation structure comprises a liquid collecting disc, a supporting sleeve, a liquid inlet, a light liquid outlet and a light liquid backflow cavity. The light liquid outlet and the light liquid backflow cavity are of downwards-oblique structures relative to the liquid collecting disc. The liquid separation structure used for the tubular centrifuging machine has the beneficial effects that the structural design is reasonable, the work state is stable, a conical leaking hole structure is additionally arranged on the light liquid backflow cavity or a heavy liquid backflow cavity, it is ensured that liquid separation is efficient and table, and in addition, cleaning does not need to be conducted frequently, wherein automatic falling is achieved based on gravity, for example, liquid in the light liquid backflow cavity flows into a heavy liquid outlet at the lower portion through a conical leaking hole; and the phenomenon that cleaning is not convenient at present is avoided as well, flushing water forms circulation in the light liquid backflow cavity or the heavy liquid backflow cavity through the conical leaking hole, the yield is increased, quality, precision and efficiency are improved, energy consumption is reduced, raw materials are saved, and the production processes are reduced.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment application, and in particular relates to a liquid separation structure for a tubular centrifuge, which improves the liquid separation structure of the existing tubular centrifuge and improves the light liquid reflux on the liquid separation structure cavity or heavy liquid reflux cavity to ensure efficient and stable liquid separation without frequent cleaning, which also solves the existing inconvenient cleaning phenomenon. Background technique [0002] There are two series of tubular centrifuges, GF and GQ, typical ones are GQ series clarification tubular centrifuges, GF series liquid and liquid separation tubular centrifuges. [0003] GF—separation type: mainly used for separation of various difficult-to-separate emulsions, especially suitable for separation of liquids and liquids with little difference in density between the two phases (the difference in specific gra...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of tubular centrifuges are intermittent operation, small drum volume, frequent shutdowns to remove sediment and low separation efficiency, cumbersome and time-consuming cleaning, so it is necessary to strengthen the tubular centrifuge by strengthening the study of separation theory and centrifugal separation process. machine separation performance
