Multipath sewage filtering apparatus

Abstract

The invention belongs to a multipath sewage filtering apparatus which mainly comprises a housing and a tubular filter screen. The multipath sewage filtering apparatus is at least provided with a double-screen filter unit. The double-screen filter unit has a structure that the housing is a seal housing; a filtered water chamber is arranged at the middle part of the housing, a unfiltered water chamber is arranged at the upper side of the filtered water chamber; the lower side of the filtered water chamber is divided by a top cover support to form a self-cleaning chamber; the tubular filter screen is a cylindrical filter screen with openings at both ends, and the upper end and the lower end of the filtered water chamber are communicated through the tubular filter screen; and a secondary filter screen is a cylindrical filter screen with openings at both ends. A self-cleaning device comprises a motor, a motor shaft, a shaft seal, a coupling, a brush rod shaft, and brush hair positioned on the brush rod shaft. Because of adopting the double-screen filter unit, the multipath sewage filtering apparatus has the advantages of small volume, simple installation and use, convenient, automatic and mechanical clean of the filter screens, good filtering effect, no occurrence of the phenomenon that pump blockage affects the cyclic utilization of water and obvious water saving effect.

Description

technical field [0001] The invention belongs to a multi-channel sewage filtering device. Background technique [0002] At present, the water shortage in cities is becoming more and more serious. In order to save water, most of the used domestic water can be recycled, such as washing vegetables, washing hands, bathing, laundry and other domestic water. Reusing domestic water is an inevitable trend of urban water conservation. Most of the used domestic water contains impurities and needs to be filtered and lifted to a certain height before it can be reused. However, the current sewage filtration devices are scattered and installed, which is troublesome to install and use. The cleaning of the filter screen is complicated and frequent, especially the filtering effect is not ideal, which often causes the blockage of the pump. Water recycling. Contents of the invention [0003] The purpose of the present invention is to provide a multi-channel sewage filtering device, which ado...
