Description

Shearing device for filtering film

Technical Field

Background

Microfiltration, also called microporous filtration, belongs to the field of precise filtration, and retains particles such as gravel, silt, clay, giardia, cryptosporidium, algae, bacteria, etc. in solution, and a large amount of solvents, small molecules and a small amount of macromolecular solutes can permeate through the separation process of a membrane.

The basic principle is that in the sieving process, the operation pressure is generally 0.7-7kPa, and the raw material liquid is permeated through a filtering material under the action of static pressure difference. The filter material may be classified into various types such as a pleated filter element, a melt-blown filter element, a bag-type dust collector, a microfiltration membrane, and the like. The microporous filter membrane made of cellulose or polymer material is utilized to retain particles, bacteria and the like in water by utilizing the uniform pore diameter of the microporous filter membrane, so that the particles, bacteria and the like cannot pass through the filter membrane to be removed.

When the filter membrane cylinder is placed, the filter membrane cylinder needs to be lifted and placed, so that the filter membrane is easy to damage when the filter membrane cylinder is placed at a required position, and the filter membrane cannot be effectively and nondestructively extracted in the filter membrane conveying process, so that the filter membrane is conveyed to be sheared, the shearing effect is poor, and wrinkles exist on the surface of the filter membrane.
