Household reverse osmosis membrane without raw water seal ring and membrane shell assembly

Abstract

The invention discloses a household reverse osmosis membrane without a raw water seal ring and a membrane shell assembly. The reverse osmosis membrane and the membrane shell assembly are included; thereverse osmosis membrane comprises a center tube and a membrane body; the membrane shell assembly comprises a membrane shell cover and a membrane shell barrel; the membrane body outer diameter is slightly smaller than the membrane shell inner diameter, a compression ring is arranged in the membrane shell barrel, and the outer diameter of the compression ring is equal to the inner diameter of themembrane shell barrel; the outer end and the inner end of the compression ring make contact with the inner surface of the membrane shell cover and the head end face of the membrane body respectively,and pressing is conducted; when the compression spring is pressed, the inner end of the compression spring can block a gap between the membrane body of the reverse osmosis membrane and the membrane shell through the compression ring; meanwhile, due to the fact that an existing raw water seal ring and adhesive tape making the raw water seal ring fixed to the membrane body are omitted, the materialsand the labor hour are saved, the effective membrane area is increased, and the water yield of a single membrane is increased.

Description

technical field [0001] The invention belongs to the technical field of reverse osmosis membrane elements, and in particular relates to a household reverse osmosis membrane and a membrane housing assembly without a raw water sealing ring. Background technique [0002] At the end of the production process of the household reverse osmosis membrane, the raw water sealing ring will be placed on the membrane body at the designated position, and then the raw water sealing ring will be fixed on the membrane body with tape. After these tasks are completed, the reverse osmosis membrane can be installed in the membrane shell for further processing Performance test or normal use. refer to figure 1 , 2 , the function of the raw water sealing ring is to prevent the raw water from passing through the gap between the reverse osmosis membrane body and the membrane shell cylinder, so that all the raw water enters the reverse osmosis membrane through the raw water channel of the reverse osmo...

AI Technical Summary

Problems solved by technology

refer to figure 1 , 2 , the function of the raw water sealing ring is to prevent the raw water from passing through the gap between the reverse osmosis membrane body and the membrane shell cylinder, so that all the raw water enters the reverse osmosis membrane through the raw water channel of the reverse osmosis membrane, thereby producing water under the action of pressure, but Due to the existence of the raw water sealing ring, the diameter of the reverse osmosis membrane can only be smaller than the inner diameter of the membrane casing, which will waste a part of the space in the cylinder. At the same time, assembling the raw water sealing ring will consume a part of man-hours. The permeable membrane will show a state of thick at one end and thin at the other end, which is not conducive to storage and turnover
