Abstract

The invention relates to a centrifugal solid-liquid separation device, in particular to a solid-liquid separation device, and provides a device which can treat complicated working conditions, has high efficiency and is easy to control. The solid-liquid separation device comprises an inlet (5), an overflow port (4), a drain outlet (11), a sewage storage chamber (8), and an observation chamber; a bracket (7) arranged in the sewage storage chamber (8) is provided with a self-rotating disk (6); an auxiliary filtration mechanism comprises a first-stage filter sieve (1), a second-stage filter sieve (2) and a third-stage filter sieve (3); and a drain automatic control mechanism comprises a sensor (9), a control unit (12), a control valve (10) and a power supply (13) for supplying power to the control unit (12) and the control valve (10). By the structure, the workload of a cyclone is reduced, the solid-liquid separation device has the capacity of treating complicated working conditions, the change of particle content can be treated by the frequency and duration of opening the drain outlet, the control is simple and the cost is low; and a problem that the particle aggregation velocity in the sewage storage chamber is not predictable is solved and automatic control is realized.

Description

technical field [0001] The invention relates to a centrifugal solid-liquid separation device, in particular to a solid-liquid separation device. Background technique [0002] The cyclone is a device that uses strong centrifugal force to separate liquid-liquid or solid-liquid phases with different densities. It has the advantages of simple structure, small footprint, large processing capacity and simple process. Its application range is wider and wider, such as Nuclear industry, shipbuilding industry, food processing industry, biological engineering, mineral processing, environmental protection, urban wastewater treatment and other fields. In the fields of urban wastewater treatment and drilling waste liquid treatment, waste liquid has the following characteristics: small particle size, large range, and large particle content changes. This is determined by its working conditions, such as the working conditions of drilling waste fluid treatment, different regions, different g...
