[0001] The utility model belongs to the technical field of polyethylene filter discs, and in particular relates to a rotary polyethylene filter membrane disc. Background Art
[0002] The filter membrane disc is the core component of the filter. It is often used in food and drug production. The rotating polyethylene filter membrane disc refers to a filter disc made of polyethylene as raw material. When working, the polyethylene filter membrane disc will be in a rotating working state. The centrifugal force generated by the rotation is used as the driving force to generate a high shear rate on the membrane surface to form a vortex sweep flow. Under the action of the shear force, the filter cake layer on the surface of the filter membrane is very thin or even exposed, avoiding the formation of a blockage layer, thereby not hindering the permeation flow.
[0003] The filtered impurities are trapped on the outer surface of the polyethylene filter disc and can be easily removed by rotating the filter disc to ensure continuous filtration. However, rotation can only remove most of the impurities. If some impurities are adhered to the outer surface of the polyethylene filter disc, it is difficult to remove them by rotating centrifugal force.
