Problems solved by technology

[0004] But this sewage sundry filtering device still has weak point when using, and the one, its filter screen and scraping device each need a motor to drive, energy consumption is higher, also easily can't work because of failure; The fixed part of the filter screen is subject to high-intensity water flow impact for a long time, and is prone to damage; the third is that it can only perform single-stage filtration, and cannot achieve multi-stage filtration

Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides an auxiliary device for filtering debris for urban sewage treatment, including a vertical filter box 1, a primary filter mechanism, a secondary filter mechanism and a tertiary filter mechanism. , Level 3 mainly refers to the precision of filtering. The lower the level, the higher the precision of filtering.

[0025] In this embodiment, the top end of the vertical filte...

Abstract

The invention belongs to the technical field of urban sewage treatment, and particularly relates to an auxiliary impurity filtering device and method for urban sewage treatment, the device comprises a vertical filtering box, a first-stage filtering mechanism, a second-stage filtering mechanism and a third-stage filtering mechanism, the vertical filtering box is provided with a sewage inlet and a sewage outlet, and the vertical filtering box is provided with a cleaning pipe and a third-stage scraping plate assembly; the first-stage filtering mechanism is composed of a first-stage filtering cylinder, a first-stage rotary driving assembly, a first-stage rotary supporting assembly and a first-stage scraping plate assembly; the second-stage filtering mechanism is composed of a second-stage filtering cylinder, a second-stage rotating driving assembly, a second-stage rotating supporting assembly and a second-stage scraping plate assembly; the third-stage filtering mechanism is composed of a third-stage filtering cylinder, a third-stage rotation driving assembly and a third-stage rotation supporting assembly. The outer-layer filtering mechanism can intercept large-size impurities, the middle-layer filtering mechanism can intercept small-size impurities, and the small-size impurities are flapped through the scraper assembly, so that the small-size impurities can enter the first-stage filtering cylinder, and the hidden danger of blockage is eliminated.

Description

technical field [0001] The invention belongs to the technical field of urban sewage treatment, and in particular relates to an auxiliary device and method for filtering debris for urban sewage treatment. Background technique [0002] As we all know, with the development of economy and society, the pressure of urban water shortage is increasing, and people are more and more aware that the social cycle of water exceeds the range that the natural cycle of water can carry, which is the root cause of pollution. It is the key to reduce pollution and relieve the pressure of water shortage, improve water utilization efficiency and strengthen sewage recycling. Treatment equipment is a device for purifying sewage efficiency, which has been widely used in the field of sewage treatment. The existing sewage treatment may face a large number of large-volume sundries in the preliminary sewage treatment process, which brings trouble to people's cleaning, and requires manual cleaning, which...
