Sewage filtering treatment device and using method thereof

Abstract

The invention discloses a sewage filtering treatment device and a using method thereof, and relates to a filtering device. An upper section of a first filter cartridge is arranged inclinedly, the lower section of the first filter cartridge is arranged vertically, and a part, close to the top of the first filter cartridge is provided with a water inlet; a spiral blade shaft is arranged in the uppersection of the first filter cartridge and is driven by a first driving motor, a blade is provided with a water passing hole, a second filter cartridge is arranged below the first filter cartridge, arotary drum is rotatably and hermetically arranged between the first filter cartridge and the second filter cartridge, and the rotary drum is driven by a second driving motor; an annular groove is formed in the bottom end of a conical filter screen and is fixedly connected with the inner wall of the second filter cartridge, a slope block is fixed on the annular groove, a leakage hole is formed inthe a part, adjacent to the slope top, of the slope block and is communicated with a sand discharging pipe, a mounting frame is fixed on the inner wall of the rotary drum, and the lower end of a telescopic scraper mounted by the mounting frame is elastically supported on the annular groove; a funnel is fixed in the lower section of the first filter cartridge and corresponds to the tip of the conical filter screen, and a water storage tank is fixedly communicated with the bottom end of the second filter cartridge. The device can continuously scrape and discharge impurities, and is simple in structure, not prone to blockage and high in continuous operation capacity.

Description

technical field [0001] The invention relates to a filter device, in particular to a sewage filter treatment device and a use method thereof, which belong to the technical field of sewage treatment. Background technique [0002] With the increase of sewage discharge year by year, the pollution to the environment has become more and more serious, and people have become more aware of the importance of sewage treatment before discharge. [0003] Sewage treatment requires preliminary filtration to filter out the larger debris and some sandstones in the sewage before subsequent chemical / biological treatment can be carried out. However, the currently commonly used sewage filtration treatment devices generally adopt the form of multi-stage filter screens, which have the problem of easy clogging and weak continuous operation ability. It is often necessary to manually dredge the filter screens, which affects the filtration efficiency. Therefore, there is an urgent need for a sewage f...
