Sewage treatment filtering device

Abstract

The invention discloses a sewage treatment filtering device, which comprises a box body and a plurality of supporting columns arranged at the lower end of the box body, wherein a water inlet connectoris formed in the upper end of the box body and communicated with a water inlet pipe, a rotary drum is rotatably connected into the box body, and a water outlet pipe communicated with the rotary drumis arranged at the side end of the box body; a partition plate, a through groove, a filtering assembly and a sealing plate are arranged on the rotary drum; and a driving assembly for driving the sealing plate to perform sealing work is arranged on the rotary drum, and a cleaning assembly for cleaning the filtering assembly is arranged on the box body. The rotating drum rotates to enable the contact on the rotating drum to be in periodic contact with the contact block and the empty groove on the box body, so that the energized magnet is periodically energized or not, the energized magnet periodically generates magnetism, the permanent magnet drives the sealing plate to move in the sliding groove, and the through groove can be opened and closed; and then the sewage is filtered through the filter screen on the through groove, and the filtered sewage falls into the rotary drum and then is discharged out of the box body through the water outlet pipe due to the fact that the rotary drum is obliquely arranged in the box body.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a sewage treatment filtering device. Background technique [0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and the sewage will also enter the human body and affect human health. The existing sewage treatment tanks cannot filter the sewage, so that the sewage contains solid pollutants, which leads to the inability to purify the solid pollutants in time, making the sewage discharge not up to standard. In addition, the sewage cannot be recycled and purified, resulting in a low purification effect. [0003] Traditional sewage trea...

AI Technical Summary

Problems solved by technology

The existing sewage treatment tank cannot filter the sewage, so that the sewage contains solid pollutants, which leads to the inability to purify the solid pollutants in time, making the sewage discharge not up to standard. In addition, the sewage cannot be recycled and purified, resulting in a low purification effect

[0003] Traditional sewage treatment and filtration devices often use filter screens to filter out large particles. After a long period of filtering work, a large number of large particles accumulate in the filter holes, which makes the filtering effect of the filter screen worse.
