An energy-saving and environment-friendly filter plate

Abstract

The invention provides an energy-saving and environment-friendly filtering plate which comprises a frame body, middle supporting nets and filtering nets, wherein the frame body is a filtering plate body; a liquid outlet end socket is arranged at one end of the frame body, and the other end of the frame body is provided with a purified liquid cavity; the purified liquid cavity is a hollow polygonal column body, and two surfaces of the purified liquid cavity are symmetric filtering surfaces; supporting plates are arranged at the peripheries of the two symmetric filtering surfaces of the hollow polygonal column body; supporting ribs are arranged in the hollow polygonal column body of the purified liquid cavity; the middle supporting nets are respectively paved and cover the upper surface and the lower surface of the purified liquid cavity so as to be connected with the supporting plates and the supporting ribs; the filtering nets are respectively paved on the middle supporting nets and are connected with the supporting plates to form the filtering plate. The filtering plate is made of a stainless steel material, is suitable for multiple industrial fields and is easy to manufacture; the product filtering precision is high, and the service life is long; the filtering nets are easy to replace, and a base plate can be repeatedly used; the replaced filtering nets can be recycled and regenerated, so that cyclic economy is achieved; a foundation is laid for 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 energy-saving and environment-friendly 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.

[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; some filter plates are formed by connecting two filter screens, if one filter screen needs to be replaced, the other also needs to be replaced at the same time, a serious waste of resources

[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, the industry has not achieved standardization
