Reverse osmosis membrane filter element and water purifier

Abstract

The invention relates to a reverse osmosis membrane filter element and a water purifier. The reverse osmosis membrane filter element comprises a center piece, water inlet pipes and reverse osmosis membrane components, wherein the side walls of the water inlet pipes are provided with a plurality of raw water outlet holes, at least one end of each water inlet pipe is provided with a raw material inlet hole, and the plurality of water inlet pipes are arranged around the center piece so as to form a central pipe group; the plurality of reverse osmosis membrane components are available; the reverseosmosis membranes of the reverse osmosis membrane components are arranged between the center piece and the water inlet pipes in a penetrating way and are rolled up around the central pipe group so asto form water inlet flow channels and a water production flow channel; the reverse osmosis membrane components comprise water inlet grids which are respectively arranged in all the water inlet flow channels; the starting sides of the water inlet grids are connected with the mounting outer walls of the water inlet pipes; the mounting outer walls of the water inlet pipes are the side walls, far away from the center piece, of the water inlet pipes. The reverse osmosis membrane filter element and the water purifier which are provided by the invention can increase the filter element rolling production efficiency and the filter element water yield.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a reverse osmosis membrane filter element and a water purifier. Background technique [0002] The existing reverse osmosis membrane filter element comprises a central tube group and a plurality of reverse osmosis membrane bags wound circumferentially around the central tube group. The central tube group includes pure water pipes and multiple water inlet pipes arranged at intervals around the pure water pipes; the reverse osmosis membrane bag includes multiple reverse osmosis membranes, multiple water inlet grids, and multiple pure water guides; One end of the osmotic membrane bag passes between the pure water pipe and a water inlet pipe and then folded in half, so that the front of each reverse osmosis membrane is surrounded to form an inlet flow channel connected with the water inlet, and the reverse side of the adjacent reverse osmosis membrane is surrounded to form a Product...
