Membrane processing device

Abstract

The invention relates to a filtering device, in particular relates to a processing device for a filtering film, and aims at overcoming the shortages that the uniformity of coating powder of a coiled film formed by coiling an existing filtering film is poor, the tightness of the coiled film cannot be effectively controlled, and the efficiency is low. The processing device for the filtering film comprises a conveying device for flattening the filtering film and moving the filtering film, and a coating device for coating and brushing the surface of the filtering film, wherein the conveying device comprises at least two coiling barrels, wherein the space between adjacent coiling barrels can be adjusted; the filtering film is tensioned through a first coiling barrel at the most front end and a second coiling barrel at the rearmost end of the conveying device, and the filtering film is arranged between the conveying device and the conveying device; the coating device comprises a coating funnel and a coating and brushing device; at least two layers of sieving hole plate structures are arranged on the bottom surface of the coating funnel. According to the processing device, the coiling barrels capable of tensioning the filtering film are arranged, so that the tightness of the filtering film can be effectively and uniformly controlled.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter membrane processing device. Background technique [0002] At present, the process of sintering metal porous filter membrane is to place the membrane blank on the platform first, and then spread a layer of powder evenly by hand. The powder here can be alumina (to prevent the membrane blank from sticking), and then filter the membrane blank. Rolled into a cylindrical shape, and then put into the furnace for sintering. [0003] At present, the entire process of making filter membrane rolls is completely manual, and the uniformity of powder coating and the tightness of the roll film cannot be effectively controlled, and the efficiency is low. The uniformity of powder application and the tightness of the roll film will affect the quality of the roll film product. When the material powder is applied unevenly, adhesion will occur when the filter membrane is sintered in the furnace. When the...

The uniformity of powder application and the tightness of the roll film will affect the quality of the roll film product

When the material powder is applied unevenly, the filter membrane will stick when it is sintered in the furnace. When the tightness of the rolled membrane cannot be effectively controlled, the surface of the membrane will be uneven. These defects seriously affect the quality of the rolled membrane product.
