Domestic sewage environmental filtering drain tank

Abstract

The invention belongs to the technical field of sewage filtration and discloses a domestic sewage environmental filtering drain tank. The domestic sewage environmental filtering drain tank comprises avegetable basin, a link pipe, a filter cake, a sealing cover, an overflow pipeline, a first sewage pipeline, a lift cage and a second sewage pipeline. Through an overflow opening provided with a filter screen, water in the vegetable basin can be prevented from overflowing out of the vegetable basin, and residue in the vegetable basin can be prevented from flowing into the overflow pipeline through the overflow opening so as to avoid the sewer from being clogged. With the filter cake disposed in a circular hole and through rubber sealing, the filter cake can be taken and residue is convenientto clean. Through the arrangement of the lift cage and by putting multiple freely-placed balls in the lift cage, a flexural slit is formed, fine residues can be filtered in the lift cage, and a lift cage hole will not be blocked and discharge of sewage will not be affected. Through the arrangement of a baffle plate, discharge of sewage will not be affected, and pollution caused by sewage backflowalso can be prevented.

Description

technical field [0001] The invention relates to a filtering device, in particular to an environment-friendly filtering drainage tank for domestic sewage, which belongs to the technical field of sewage filtering. Background technique [0002] The drainage tank is an instrument used to collect gas by drainage method or to hold a large amount of water and to wash tableware and food. Its main material is stainless steel. In addition to stainless steel, there are also iron enamel, ceramics, etc. Kitchen gutters are divided into cast iron enamel, ceramics, stainless steel, artificial stone, granite gutters (quartz stone mixed resin), steel plate enamel, acrylic, crystal stone gutters, etc. according to the style; Divided into single basin, double basin, large and small double basin, special-shaped double basin and so on.

Problems solved by technology

[0003] Kitchen drains are now popular in every household, and the utilization rate is very high. When cleaning kitchen supplies, it is inevitable that a lot of residue will be generated. When a large amount of residue falls into the sewer through the drain, it will cause sewer blockage, and at the same time produce bacteria and stench. It is harmful to people's health. Therefore, it is very important to do a good job of filtering kitchen residues. Kitchen sinks on the market usually only have a simple filter screen to filter food residues. Some small residues will still flow into the sewer through the filter holes. Common The drain hole at the lower end of the push-type water seal cover is usually integrated with the drain tank, so it is inconvenient to unblock when the sewer is blocked. In the case of humid weather, the sewer will produce peculiar smell, which is not good for human health. For this reason, we Propose an environmental protection filter drainage tank for domestic sewage
