Solid-liquid separation device for domestic sewage treatment

Abstract

The invention relates to the technical field of domestic sewage, and discloses a solid-liquid separation device for domestic sewage treatment. Through cooperative use of a baffle plate, a second connecting rod and a half gear, during sewage filtration, sewage can be introduced intermittently , a continuous introduction mode is changed, the situation that a filter screen is in an impact state continuously in the process of continuously introducing sewage, and certain time cannot be reserved for buffering is avoided, and the service life is prolonged. Through cooperative use of a sieve plate, a scraper, an upper vibration plate, a first connecting rod and a first rotating disc, in the process of sewage solid-liquid treatment, the sieve plate can be automatically vibrated, and therefore, the filtering efficiency is improved. Meanwhile, scraping is conducted through the scraper, and blocking of the filter screen is avoided. Through cooperative use of a third rotating disc, a first disc, a second disc and a limiting sleeve, the two steps of vibration of the filter screen and automatic intermittent sewage introduction are linked, and therefore the linkage performance of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage, in particular to a solid-liquid separation device for domestic sewage treatment. Background technique [0002] With the increase of urban population and the development of industrial and agricultural production, domestic sewage discharge is also increasing, and water pollution is quite serious. In order to improve water quality, solid-liquid separation for sewage treatment is one of the basic operations. However, the existing solid-liquid separation device is relatively simple to set up. Usually, the sewage is continuously filtered through the filter screen. On the one hand, when the sewage is continuously introduced, the filter screen does not have a certain Time is buffered, thereby shortening the service life of the filter. On the other hand, during the filtering process, the filter screen is in a static state, which makes the filter screen extremely prone to blockage, thereby reducin...

Problems solved by technology

However, the existing solid-liquid separation device is relatively simple to set up. Usually, the sewage is continuously filtered through the filter screen. On the one hand, when the sewage is continuously passed through, the filter screen does not have a certain Time to buffer, thereby shortening the service life of the filter

On the other hand, during the filtering process, the filter screen is in a static state, which causes the filter screen to be easily blocked, thereby reducing the working efficiency of solid-liquid separation

[0003] Aiming at the deficiencies of the prior art, the present invention provides a solid-liquid separation device for dom
