Solid-liquid separation device applied to sewage treatment system

Abstract

The invention discloses a solid-liquid separation device applied to the sewage treatment system. The device comprises a box body, water outlets are formed in the two sides of the outer wall of the bottom of the box body, first filter screens are fixedly connected to the inner walls of the two water outlets, a plurality of filter holes are formed in the outer walls of the two sides of the box body,a box cover is fixedly connected to the outer wall of the top of the box body, a water inlet is formed in the outer wall of the top of the box cover, a filter cone is fixedly connected to the inner wall of the water inlet, a fixing block is fixedly connected to the inner wall of the bottom of the box body, telescopic rods are connected to the outer walls of the two sides of the fixing block through hinges, and extrusion plates are connected to the outer walls of one sides of the two telescopic rods through hinges. According to the device, solid waste can be subjected to extrusion treatment, the situation that the device cannot effectively conduct solid-liquid separation on the sewage due to the fact that the impact strength of the sewage is weak can be prevented, the solid waste doped inthe sewage can be retained on the second guide plate, and the situation that the solid waste falls off from the hanging piece due to water flow can be prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solid-liquid separation device applied to a sewage treatment system. Background technique [0002] At present, in terms of sewage treatment, it is divided into three stages of treatment, of which the stage one includes solid-liquid separation, and its main function is to separate the larger solids contained in the liquid. [0003] After retrieval, the Chinese patent authorization number is CN107935108B, which discloses a solid-liquid separation device for primary sewage treatment, including a bottom hollow shell and a top hollow shell. The bottom of the bottom hollow shell is equipped with a plurality of connecting plates through bolts, each A support rod is installed at the center of the bottom of each connecting plate. The present invention utilizes the principle of centrifugal force to realize the filtering effect, and the device can freely assemble and disassemble...

Problems solved by technology

A solid-liquid separation device for primary sewage treatment in the above-mentioned patent has the following disadvantages: when the existing device separates sewage from solid-liquid, part of the sewage will be submerged in the solid waste. Therefore, when separating solid-liquid When the sewage is submerged in the solid waste, it may affect the efficiency of solid-liquid separation of sewage
