Pore shaft water supply filter assembly and filter system

Abstract

The invention discloses a pore shaft water supply filter assembly and a filter system. A filter layer of the pore shaft water supply filter assembly is a filter material which surrounds outside an inner cylinder body to be folded into a wave shape, a pore shaft is arranged outside each folding point of the filter material, which is adjacent to the inner cylinder body, the axial line of each pore shaft is parallel to the axial line of the inner cylinder body, each pore shaft is a pipe body, and all hinges of the filter material are tightly wound on a combination body of the inner cylinder body and all pore shafts along the same direction. According to the filter system, a plurality of filter assemblies are adopted. The filter material is supported by the pore shafts to form an arc surface, clear water of concentrated water, which is filtered from the arc surface, enters the inner cylinder body, and the filter material has no bevels in the arc surface without forming dead angles or causing impurity accumulation or blocking a filter layer; and during backwashing after filtering, a cleaning solution enters the pore shafts from the inner cylinder body through the arc surface of the filter material, so that impurities on the filter layer can be easily washed out and can be discharged out together with the cleaning solution.

Description

technical field [0001] The invention relates to a separator assembly, in particular to a hole-shaft water feed filter assembly, and also to a filter system. Background technique [0002] With the continuous revolution of industry and the continuous improvement of living standards, the implementation of sustainable development strategy, the requirements for humanistic and ecological environment are getting higher and higher. Therefore, saving water resources, sanitation water and reducing water pollution are the primary strategic issues of the contemporary era, so it can solve industrial problems. The useful and effective filtration of sewage, domestic water, and industrial production water is an eternal research topic. Currently existing filtration devices mainly include membrane separation devices, vacuum drum filters, belt filters, plate and frame filters, and media filters. [0003] The membrane separation device uses the membrane as the separation medium. When there is ...

[0011] Chinese patent ZL200910258565.9 discloses a cylindrical filter assembly. All concentrated water layers and the inner cylinder are connected end-to-end in sequence from the outside to the inside. The outer cylinder is provided with a concentrated water inlet, and the inner cylinder is provided with a concentrated At the water outlet, the concentrated water flow channel is very long, and the filtration efficiency becomes lower as the concentrated water flows, which affects the overall filtration efficiency

It can only filter in one direction, and the filter can only use ordinary materials for support and turbulence

In particular, the sealing process at both ends of the filter assembly is difficult and easy to leak

[0013] Chinese patent application 201120373509.2 discloses a hinged filter assembly and filter system to achieve positive and negative filtration. Although the filter layer has a long service life, water enters from the outside of the filter layer during positive and negative filtration. There are dead corners that are folded and pasted together. Whether it is positive or reverse filtration, the concentrated liquid must pass through the dead corners of the filter layer. Impurities in the concentrated liquid will deposit in the dead corners, which will affect the filtering effect. Impurities are washed away through dead ends, the backwashing time is too long, the operating system is complicated to set up, the cost is high, the operation is difficult, the number of operations is frequent, the secondary pollution of water cannot be solved, the water consumption is serious, and there is no fundamental solution to this type of filter components cleaning problems, only a palliative solution

The hinged filter assembly is only designed with two water inlets and outlets, and the sewage can only be discharged from one port during backwashing, and the sewage discharge is not smooth. If the filter is placed vertically, the sewage can only be discharged from the upper port. This design is not scientific enough
