High-efficiency solid-liquid clarification and separation device

Abstract

The invention discloses a high-efficiency solid-liquid clarification and separation device. The device comprises a bottom bracket, a cylinder body, a flow guide device, an inclined plate, a mud scraping mechanism and a speed reducer, wherein the cylinder body is mounted on the bottom bracket, the speed reducer is arranged on the cylinder body, the flow guide device comprises a flow guide barrel and a reflecting plate, the reflecting plate is arranged below the flow guide barrel, the top of a first-stage flow guide barrel is communicated with a sewage / grey water inlet, the top of a second-stageflow guide barrel is connected to the outer side of a lower end opening of a first-stage flow guide barrel, and auxiliary scraping arms are arranged on the upper surface of a first-stage reflecting plate and the upper surface of a second-stage reflecting plate respectively, a slag / sludge concentration hopper is arranged at the bottom of the cylinder body, a scraping arm is arranged on a bottom plate of the cylinder body, and the scraping arm and auxiliary scraping arms jointly form the sludge scraping mechanism. According to the invention, the specific surface area is increased, the treatmentload is increased, the diffusion flow is enhanced by the flow guide reflection device, the water distribution is more uniform, the flow velocity is more stable, the liquid medicine is more fully mixed, and the clarification and separation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of clarification and separation of sewage / gray water with high solid content, in particular to a high-efficiency solid-liquid clarification and separation device. Background technique [0002] At present, my country's industrial project units have large water consumption and large scale, and the shortage of water resources has become a prominent contradiction restricting my country's industrial development. In order to improve the overall efficiency of water resources in the industrial production process, a high-efficiency separation technology with high solid-liquid clarification and separation efficiency, small footprint, low system operating costs, and investment savings is needed to strengthen the industrial / coal chemical process water resource recycling system. [0003] Industrial / coal chemical sewage / gray water has high solid content, fine suspended particles, and high water temperature. Its solid cont...
