Improved single-side folding screen filter plate

Abstract

The invention provides an improved single-side folding screen filter plate. The improved single-side folding screen filter plate comprises a base plate, a hole plate, a middle support screen and a filter screen, wherein the base plate is a filter plate body; a liquid outlet end is arranged at one end of the base plate; a clean liquid cavity is formed in the other end of the base plate; the clean liquid cavity is a concave cavity; support plates are arranged at the upper periphery of the concave cavity; N support ribs are arranged at the bottom in the concave cavity of the clean liquid cavity; the hole plate is paved to cover the clean liquid cavity and then is connected with the support plates and the support ribs; the middle support screen is folded to pave in a corrugate shape to cover the hole plate and the support plates and then is connected with the hole plate and the support plates; the filter screen is folded in the corrugate shape, is matched with the corrugate shape of the middle support screen and is connected with the support plate to form the filter plate, the middle support screen is paved with the filter screen; the filter plate is made of a stainless steel material; the filter plate is applicable to various industries and fields and simple to manufacture; products are high in filtering precision and long in service life; the filter screen is simple to replace; the base plate can be reused; the replaced filter screen can be recycled and regenerated, and thus the circular economy implemented and a foundation is layed for implementing standardization of 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 single-side folded mesh 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 scientifi...

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. requirements, has not been standardized
