Abstract

The invention provides a rotary RO (Reverse Osmosis) membrane filtration assembly. The rotary RO membrane filtration assembly comprises a filtering core assembly provided with an RO membrane, wherein the filtering core assembly comprises a cylindrical filtering shell and an RO membrane filtering core arranged in the filtering shell. The rotary RO membrane filtration assembly is characterized by further comprising a filtering base and a filtering cover, wherein the filtering base is provided with a source-water water inlet, a pure-water water outlet and a condensed-water water outlet which are communicated with the filtering core assembly; a plurality of clamping grooves are arranged at the lower part of the filtering base; the filtering cover is fixedly sleeved at the upper end of the filtering shell of the filtering core assembly; the upper end of the filtering cover is provided with convex lugs which are matched with the clamping grooves of the filtering base; the filtering core assembly is used for clamping the convex lugs and the clamping grooves of the filtering base through rotating the filtering cover, so that the rapid connection or separation with the filtering base is realized. According to the rotary RO membrane filtration assembly disclosed by the invention, the whole RO membrane filtration assembly is designed into a rapidly-replaced filtering core and has the characteristics of simple structure, small volume and convenience in detachment; the rotary RO membrane filtration assembly is easy for maintenance and filtering core replacement and has good sealing performance.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a rotary RO membrane filter assembly used in a filtration system of a pure water machine, which is small in size, good in sealing performance and easy to maintain. Background technique [0002] The filtration system of the existing household water purifier generally includes a coarse filtration system and a fine filtration system. The fine filtration system mainly uses RO membrane filtration components. When assembling, the RO membrane is installed in a cylindrical membrane shell. The membrane cover is covered with an O-ring and then threadedly connected to the membrane shell to achieve sealing. The source water inlet is at the membrane cover end, the pure water outlet and the concentrated water outlet are at the other end, and the entire assembly is connected to the body through a single clip. However, this method has disadvantages such as large space occupation, inconve...
