Solid-liquid separation device and system

Abstract

The invention relates to a solid-liquid separation device and system. Belongs to the technical field of solid-liquid separation technology and comprises a box body, the box body is provided with a liquid inlet, a liquid outlet and a solid outlet, a filter screen is arranged between the liquid inlet and the liquid outlet in the box body, a movable scraper is arranged above the filter screen, and two ends of the scraper extend to the outside of the box body to form sliding ends. A driving mechanism for controlling the sliding end to move is arranged on the box body, the filter screen is divided into a horizontal part and an inclined part, the liquid inlet is formed above the horizontal part, the solid outlet is in butt joint with the bottom end of the inclined part, and solids separated by the horizontal plate can be scraped to the inclined part through the movement of the scraping plate, enter the inclined part and are discharged out of the box body through the solid outlet. The device is simple in structure, and filtered impurities can be taken out under the condition that the box body is disassembled.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and in particular relates to a solid-liquid separation device and system. Background technique [0002] Solid-liquid separation equipment is a water treatment process that separates solids in sewage. It is widely used in the sewage treatment industry to remove suspended solids in water, and is generally installed in the pretreatment stage of the sewage treatment system. The current industrial sewage treatment devices generally flow sewage into the sewage tank for impurity precipitation and solid-liquid separation to treat sewage, so that the sewage treatment efficiency is slow and impurities need to be slowly precipitated; or solid-liquid separation equipment is installed on the sewage sewage pipes. Solid-liquid separation of the sewage inside, patent number CN215099659U discloses a solid-liquid separation device, the device includes a filter box, a filter screen is provided in th...
