Technical Field

[0001] The utility model relates to the technical field of microfilter screens, in particular to a microfilter screen module. Background Art

[0002] As a fine filtering equipment, microfilters are widely used in the fields of sewage deep treatment, aquaculture wastewater, algae filtration, etc. It is mainly used to intercept fine substances such as suspended matter, fish feces, feed residues, algae, etc. The filtration accuracy ranges from 30 mesh to 200 mesh, and the commonly used filter screens are stainless steel woven mesh, nylon mesh, etc. The filter screen is made into a drum shape, and the water is filtered inside. The suspended matter intercepted by the filter screen is washed by spraying and discharged from the sewage outlet. It belongs to the normal pressure mechanical filtration type. Since the filter screen of the microfilter is relatively fine, the pores are small, and the wire diameter is also small, the filter screen is relatively thin. How to make a very thin filter screen into a drum becomes a technical difficulty. The common method is to make the drum into a frame form, and then lay a diamond mesh with a certain strength, or a sintered mesh, or a perforated mesh, and then wrap the fine filter screen and fix it on the grid. The manufacturing is relatively complicated and the maintenance and replacement are relatively difficult. At the same time, it also affects the filtration effect and the strength of the filter screen to a certain extent. For this reason, we propose a microfilter filter screen module.
