Membrane filter pressing device for pigment production waste slurry

Abstract

The invention discloses a membrane filter pressing device for pigment production waste slurry. The membrane filter pressing device comprises a filter pressing box body, wherein fixed mounts are weldedon the outer walls of two sides of the bottom of the filer pressing box body; membrane filter plates which are placed vertically are inserted into the inner walls of the filter pressing box body; theouter walls of the two sides of the filter pressing box body are provided with mounting holes; positioning sleeves are inserted into the inner walls of the mounting holes; the positioning sleeves areinserted into the inner walls of the membrane filter plates; feeding pipes are inserted into the inner walls of the positioning sleeves; air inlet valves are welded on the top and at the bottom of the outer wall of one side of the filter pressing box body; pushing plates are fixedly arranged on the outer walls of one ends close to the air inlet valves of the membrane filter plates. By adopting the membrane filter pressing device, slurry is recycled, a large quantity of pigment resources are saved, and pollution due to direct discharge of waste slurry into rivers is avoided; the membrane filter pressing device has the advantages of novel structure, reasonable design, low manufacturing cost, good filter pressing effect on pigment waste slurry, high automation degree and capability of achieving an effect desired by people.

Description

technical field [0001] The invention relates to the technical field of membrane filter press, in particular to a membrane filter press device for producing waste slurry from pigment production. Background technique [0002] Pigment is a substance that can make an object dyed with color. Pigments are soluble and insoluble, and there are inorganic and organic differences. Inorganic pigments are generally mineral substances. Humans have known for a long time to use inorganic pigments, using colored soil and ores, to paint on rock walls and smear their bodies. Organic pigments are generally obtained from plants and marine animals, such as madder blue, gamboge and purple extracted from shellfish in ancient Rome. In the existing pigment production process, a large amount of waste pulp will be produced. In order to save energy, protect the environment, save energy and reduce emissions If the waste is not treated in time, it will pollute the environment. The mechanical diaphragm f...

Problems solved by technology

Organic pigments are generally obtained from plants and marine animals, such as madder blue, gamboge and purple extracted from shellfish in ancient Rome. In the existing pigment production process, a large amount of waste pulp will be produced. In order to save energy, protect the environment, save energy and reduce emissions If the waste is not treated in time, it will pollute the environment. The mechanical membrane filter press has the problem of incomplete separation of mud and liquid, so it is necessary to filter the waste slurry, so as to pass the production benefits of the factory, but the existing filter press The device cannot handle the waste pulp well, therefore, it is necessary to provide a new technical solution to solve the above problems
