Efficient domestic sewage separation device

Abstract

The invention provides an efficient domestic sewage separation device, which comprises a hollow cylindrical sewage treatment tank with a cover plate at the top end, a filter vat, a stirring scraper and a hole cleaning barrel, wherein the filter vat is arranged at the center of the sewage treatment tank, filter holes are uniformly distributed in the side wall of the filter vat, a sundry opening is formed in the bottom of the filter vat and the top end of the filter vat is connected with a first rotating shaft; the first rotating shaft is driven by a first motor; the bottom of the sewage treatment tank is connected with the lower segment of the filter vat through an annular bottom plate which inclines towards the center of the inner side; the stirring scraper is arranged in the filter vat and comprises a second rotating shaft and a spiral plate arranged on the second rotating shaft; the second rotating shaft is driven by a second motor; and the hole cleaning barrel is arranged at one side of the filter vat, the top end is rotationally connected with the cover plate through a third rotating shaft and bumps matched with the filter holes of the filter vat are uniformly distributed on the side wall. The efficient domestic sewage separation device has the advantages that the structure is compact and reasonable, the sewage filter effect is good, insoluble waste sundries can be effectively separated, sundry residues in the filter holes are automatically cleaned and the filtering efficiency of the filter device is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency domestic sewage separation device. Background technique [0002] With the continuous progress of society and the continuous development of industry, the living environment of human beings is inevitably destroyed, and the problem of environmental pollution has attracted great attention and attention from all countries in the world. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it has also increasingly entered the daily life of ordinary people. Urban domestic sewage is mainly produced by human beings in cities. Sewage, garbage, feces, etc. generated in life, among which garbage includes plastic bags, paper and some plastic products in daily life, etc., these garbage enter the sewage treatment plant...

AI Technical Summary

Problems solved by technology

[0003] At present, the stirring zone and the filtering zone of the existing sewage treatment devices on the market are basically set separately, the device occupies a large area, and the filtration efficiency is low. It is easy to block the filter holes of the filter device, which affects the filtration efficiency. In the long run, it is easy to cause equipment damage and high maintenance costs. If the filter device is cleaned manually, the operation is difficult and the labor cost is high.
