Strip combined filter plate and filter chamber using same

Abstract

The invention discloses a strip combined filter plate and a filter chamber using the same. The strip combined filter plate comprises a plate body of which the periphery is provided with a circle of enclosure wall; and the upstream face of the plate body is provided with a plurality of protrusion parts of which the side walls are uniformly provided with filter slits. The bottom of the filter chamber is provided with a plurality of stainless steel support columns corresponding to a distance between a mounting hole and a mounting notch of the strip combined filter plate one by one; the tops of the support columns are provided with screw rods of which the diameter is smaller than that of the support columns; and the screw rods pass through the strip combined filter plate correspondingly one by one and are fastened on a support through nuts on the end parts of the screw rods. The filter slits are formed on the side walls of the protrusion parts of the filter plate and filter sand does not directly cover on the filter slits, so when water is distributed in the filter slits, the filter slits are difficult to block, and the normal use of the filter plate cannot be influenced. Besides, the mounting hole and the mounting notch are matched with the stainless steel columnar supports conveniently and firmly. The combined filter plates are in good fit, so the whole filtering surface is neat and joints are difficult to crack.

Description

technical field [0001] The invention relates to a filter plate device for water treatment, in particular to a strip-shaped combined filter plate and a filter tank for its application. Background technique [0002] At present, in a filter tank used for tap water treatment, a filter plate with many filter slits on the plate body is used. When in use, the filter sand is directly covered on the filter plate, and the water permeates through the filter sand and seeps through the filter seams. However, in the filtration process, in order to block the fine filter sand, the filter slit of the filter plate must be made very narrow. Such long-term use will cause the filter sand to block the filter seam, so as to reduce the water treatment efficiency. Secondly, with this kind of filter plate for water distribution, when multiple layers of filter sand are covered on the filter plate, backwashing can easily lead to disordered layers of filter sand, thereby affecting the normal filtratio...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the technical problems of the existing water distribution filter plate, such as large head loss, low water treatment efficiency, easy to cause disordered sand filtering during backwashing, and high production cost.

At the same time, the invention also solves the technical problems in the existing water distribution system, such as heavy filter plate structure, weak installation, large seams between filter plates, poor filtering effect, etc.
