2results about How to "Stable operating pressure" patented technology

The utility model discloses a filtering device for producing a hand-washing-free disinfectant, and relates to the technical field of filtering devices. The filtering device for producing the hand-washing-free disinfectant comprises a shell, four supporting legs capable of being leveled are fixedly installed at the bottom of the shell, and a filtering bin is fixedly installed in the shell. According to the filtering device for producing the hand-washing-free disinfectant, the detachable filtering membrane structure has the multiple advantages that assembly-level overhaul can be achieved, the whole device does not need to be disassembled, the downtime is shortened, the production continuity is improved, a single membrane is replaced according to needs, the consumable cost is reduced, membrane materials are flexibly replaced, the precision is adjusted, replaced assemblies can be independently treated, and the cost is reduced. The filtering effect is guaranteed, internal deep cleaning and disinfection are facilitated, the high-hygienic-standard production requirements of medicine, food and the like are met, layered filtering and detachable maintenance are combined, the membrane load is relieved, pollutants are removed in time, the stable operation pressure of the system is maintained, and the overall service life of equipment is prolonged.
