Multi-medium filter for filtering tap water

Abstract

The invention discloses a multi-medium filter for filtering tap water, and belongs to the technical field of tap water filtering equipment. The multi-medium filter comprises a shell and a cover plate, an upper partition plate assembly, a plurality of middle partition plate assemblies and a lower partition plate assembly are arranged in the shell, a water inlet channel is formed between the upper partition plate assembly and the cover plate, and a water outlet channel is formed between the lower partition plate assembly and the bottom of the shell; a space capable of accommodating a filter material is formed between the upper partition plate assembly and the lower partition plate assembly, and the space is divided into a plurality of small spaces by the plurality of middle partition plate assemblies; the bottom of the upper partition plate assembly, the top and the bottom of the middle partition plate assemblies and the top of the lower partition plate assembly are all provided with cleaning mechanisms capable of performing independent water vapor scrubbing on the filter materials in the corresponding small spaces; a stirring mechanism is arranged in the shell and can be used for independently stirring the filter materials in different small spaces. The invention aims to provide the multi-medium filter for filtering tap water. The function of stirring and cleaning the filter material in the filter is realized.

Description

technical field [0001] The invention relates to the technical field of tap water filtering equipment, in particular to a multi-media filter for tap water filtration. Background technique [0002] Tap water filter is a common equipment in the prior art, mainly used for filtering tap water, and it generally consists of limestone layer, river sand layer, anthracite layer and activated carbon layer arranged in sequence from bottom to top. At present, after the filter is used for a period of time, the upper anthracite layer and activated carbon layer will filter out more impurities, and the impurities will cover the surface of the anthracite layer and activated carbon layer, causing it to harden, which will eventually lead to poor filtering effect and smaller water output. The problem. Contents of the invention [0003] At present, the treatment method for the above phenomenon in the prior art is to backwash the filter material at the bottom layer with water. However, due to t...

Problems solved by technology

[0003] At present, the treatment method for the above phenomenon in the prior art is to backwash the filter material at the bottom layer with water, but due to the hardening problem of each layer, the particles are not easy to loosen, and there is no friction between the particles, resulting in poor cleaning effect

In order to overcome the above deficiencies, the present invention provides a multi-media filter for tap water filtration, which uses high-pressure water and air to scrub each layer of filter material separately, and at the same time, combines a unique stirring mechanism to separately stir each layer of filter material, and finally solves the problem of filter problems caused by filtration. The problem of poor cleaning effect caused by material particle compaction
