Improved filtering plate

Abstract

The invention provides an improved filtering plate. The improved filtering plate comprises a bottom plate, a middle supporting net and a filtering net, wherein the bottom plate is a filtering plate body; one end of the bottom plate is provided with a liquid discharging end, and the other end of the bottom plate is provided with a liquid purifying cavity body; the liquid purifying cavity body is a concave cavity; supporting plates are arranged at the periphery of the concave cavity; N supporting ribs are arranged at the bottom in the concave cavity of the liquid purifying cavity body; the middle supporting net is flatly laid to cover the upper part of the liquid purifying cavity body and is connected with the supporting plates and the supporting ribs; the filtering net is flatly laid on the middle supporting net and is connected with the supporting plates. The improved filtering plate provided by the invention is made of stainless-steel materials, is applicable to a relatively large quantity of industries and fields, and has advantages that the manufacture is simple, the filtering accuracy of products is high, the service life is long, the replacement of the filtering net is simple, the bottom plate can be repeatedly used, and the replaced filtering net can be recycled, so that the cyclic economy is implemented, and the foundation is laid for realizing the standardization in the field.

Description

technical field [0001] The invention relates to a metal filter plate in the field of liquid filtration in industries such as medicine, chemical industry, sewage, light industry and beverage, and in particular to an improved filter plate made of stainless steel. Background technique [0002] At present, in the liquid filtration of medicine, chemical industry, sewage, light industry, beverage and other industries, there are many kinds of liquid filter discs on the market. The patent number 2011101748533 I applied for, patent name: a method for making an improved disc filter disc , Authorized announcement number: CN102294139B, the manufacturing method of this patent is more scientific, but the loading and unloading hole is in the center, if a single filter needs to be maintained, it cannot be directly disassembled arbitrarily; there are many kinds of filters on the market that can be disassembled separately, but the process The principle is not scientific enough, especially for...

Problems solved by technology

[0002] At present, in the liquid filtration of medicine, chemical industry, sewage, light industry, beverage and other industries, there are many kinds of liquid filter discs on the market. The patent number 2011101748533 I applied for, patent name: a method for making an improved disc filter disc , Authorized announcement number: CN102294139B, the manufacturing method of this patent is more scientific, but the loading and unloading hole is in the center, if a single filter needs to be maintained, it cannot be directly disassembled arbitrarily; there are many kinds of filters on the market that can be disassembled separately, but the process The principle is not scientific enough, especially for filtering high-precision liquids, the required filter plate has higher filtration accuracy, so the manufacturing process requirements are more scientific to meet the filtration requirements; The filter plate produced by the process cannot meet the requirements of high-precision liquid filtration; patent number 2007100548270, patent name: a fan-shaped plate for a disc filter with a unique flow channel, and its filtration accuracy requires additional filter cloth, and the fan-shaped plate is only The role of frame support is difficult to meet the needs of high-precision liquid filtration

[0003] To sum up, the filter plates on the market have their own advantages, but there are few filter plates that require high filtration accuracy and meet scientific and practical requirements, especially metal filter plates made of stainless steel, and the current filter plate technology cannot satisfy market development. needs
