Solid-liquid separation device for primary sewage treatment

Abstract

The invention discloses a solid-liquid separation device for primary sewage treatment. The device comprises a bottom hollow case and a top hollow case, wherein the bottom of the bottom hollow case isprovided with a plurality of connecting plates through screw bolts; one support rod is arranged in the center of the bottom of each connecting plate. The centrifugal force principle is used to realizethe filtering effect; by using the device, the bottom hollow case and the top hollow case can be freely combined or dismounted, so that inside filtered sundries can be conveniently discharged. In addition, through a centrifugal filtering rotating mechanism arranged in the device, when inside sewage rotates to generate an eddy current phenomenon, the eddy current enables impurities in the sewage to generate the centrifugation phenomenon, so that the impurities can move towards the outer side; liquid in the sewage can enter the inside of a hollow structure for the centrifugal filtering rotatingmechanism through a filter hole for the centrifugal filtering rotating mechanism; under the gravity effect, the liquid in the sewage can be discharged out through a main liquid discharging pipeline;when an electric motor rotates faster, when the generated centrifugal force effect is stronger, the filtering effect is better; the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solid-liquid separation device for primary sewage treatment. Background technique [0002] At present, in terms of sewage treatment, it is divided into three levels of treatment, of which the first level of treatment includes solid-liquid separation. Its main function is to separate the larger solids contained in the liquid, and the general separation method is through filtration. Separate filtration, and then its filtration is only divided into a simple step of filtration, most of which are filtered by the filter screen. Due to the many defects of the filter screen, the filtration range is low, the efficiency is low, and it has great limitations. Contents of the invention [0003] The object of the present invention is to provide a solid-liquid separation device for primary sewage treatment to solve the problems raised in the above-mentioned background technology. ...
