RO membrane filter element assembly

Abstract

The invention discloses an RO membrane filter element assembly. The RO membrane filter element assembly comprises an RO membrane filter element, a filter bottle and a filter bottle cap, wherein the ROmembrane filter element is installed in the filter bottle, and a pure water port is formed in the center of the filter bottle cap; the RO membrane filter element comprises a central pipe and a membrane wound on the central pipe; the outer side of the membrane is sleeved with a sealing ring sleeve, the sealing ring sleeve abuts against the inner wall of the filter bottle to divide the filter bottle into a raw water cavity and a waste water cavity, and a water inlet and a waste water port are formed in the raw water cavity and the waste water cavity respectively; a pure water port joint and anejector rod are respectively mounted at two ends of the central pipe; one end of the ejector rod is inserted into the central pipe, and the other end of the ejector rod is inserted into and penetratesthrough a through hole in the bottom of the filter bottle; and the pure water port joint communicates with the central pipe and the pure water port on the filter bottle cap. The raw water cavity andthe waste water cavity are isolated through the sealing ring sleeve located outside the membrane, so the positions of the water inlet and the waste water port can be adjusted as required; and the ejector rod can assist in disassembling of the RO membrane filter element, so the replacement difficulty of the RO membrane filter element is reduced, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, in particular to an RO membrane filter element assembly. Background technique [0002] The RO membrane filter assembly generally includes the RO membrane filter, the RO membrane filter is installed in the filter bottle, and the filter bottle and the filter bottle cap are fixed by threaded connection. The existing RO membrane filter element includes a central tube and a diaphragm wound on the central tube. A pure water channel is arranged in the diaphragm, and a waste water channel is formed between adjacent diaphragms; the central tube is provided with a pure water concentration flow channel and A plurality of pure water through holes connecting the pure water channel and the pure water concentrated flow channel, the pure water through holes are distributed along the axial direction of the center pipe at intervals. One end of the RO membrane filter element is provided with a...
