Abstract

The invention discloses a reverse osmosis membrane element and a sealing case thereof. The reverse osmosis membrane element comprises a reverse osmosis membrane body, a water passage adapter connectedwith one end of the reverse osmosis membrane body, and the sealing case connected in a sleeve mode to the outer surface of the reverse osmosis membrane body, wherein the sealing case comprises a sealing case body in a hollow cylindrical shape; the outer circumference of the upper portion of the sealing case body is provided with an O-type sealing ring, and the sealing case body and the O-type sealing ring are integrally made of high-molecular food-grade materials. According to the reverse osmosis membrane element, the sealing case saves glue applied onto the back surface and tightly seals upthe surface of the reverse osmosis membrane body through elasticity, thereby effectively ensuring sanitary safety of the reverse osmosis membrane element; besides, with the O-type sealing ring, the sealing case saves auxiliary sealing by white tapes, simplifies assembling processes and meanwhile avoids the risk of internal leakage of a reverse osmosis filter element due to bonding failure betweenthe white tapes and concentrated water sealing rings as well as external tapes.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis filtration, in particular to a reverse osmosis membrane element and a sealing sleeve thereof. Background technique [0002] figure 1 It is a schematic diagram of a reverse osmosis membrane element in an existing snap-in household reverse osmosis membrane filter element. Such as figure 1 As shown, the reverse osmosis membrane element is composed of a waterway converter 101, a white tape 102, and a reverse osmosis membrane body 103. The reverse osmosis membrane body 103 is usually composed of a central tube, a plurality of membrane bags spirally wound on the central tube, and an outer layer of adhesive tape. . The purpose of the outer tape is to wrap and seal the spiral membrane bag to form a spiral water inlet flow channel and a water production flow channel. The purpose of the white tape 102 is to fix the water circuit converter 101 and strictly separate the raw water from the concentra...
