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 domestic sewage treatment, which has the advantages of intermittently feeding sewage and avoiding filter blockage, and solves the problem of solid-liquid separation in existing domestic sewage. When the device is set relatively simple, it ensures that the sewage can be automatically and intermittently fed into the device during operation, thereby reducing the impact of the filter, leaving a certain amount of time for buffering, prolonging the use time, and when filtering , the filter automatically vibrates to improve the filtering effect of sewage, thereby improving the working efficiency of the device and further improving the intelligence of the device

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see Figure 1-3 , a solid-liquid separation device for domestic sewage treatment, comprising a casing 1, a water inlet is arranged on the top of the casing 1, and sewage is passed through the water inlet, and the water inlet is set in an open shape to reduce the impact force of the sewage. At the same time, a water outlet is provided under the shell 1 to flow out the sewage that has completed the solid-liquid separation. The inside of the shell 1 is mov...

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...
