A reverse osmosis filter element

Abstract

The invention discloses a reverse osmosis filter element assembly, which comprises a casing and a reverse osmosis filter element. The casing includes an outer end cover and a cylindrical body. The permeation filter element includes a central tube and a membrane element, and a waterway converter is installed at one end of the reverse osmosis filter element. The waterway converter includes a first split part and a second split part assembled in the axial direction, and the second split part includes a central extension tube. There is a central flow channel in the central extension tube, the central extension tube communicates with the central tube, the first flow channel is formed between the inner wall of the first split part and the outer wall of the central extension tube, the second flow channel is formed between the waterway converter and the shell, and the central The flow channel is connected to the central pipe and the pure water outlet, the first flow channel is connected to the reverse osmosis filter element, and one end of the waterway converter is installed and one of the raw water inlet or concentrated water outlet, and the second flow channel is connected to the other end of the reverse osmosis filter element and the raw water inlet. The other of the water outlet or the concentrated water outlet. The invention is mainly used for reverse osmosis water purification.

Description

technical field [0001] The invention relates to a reverse osmosis filter element assembly, which belongs to the technical field of water treatment. Background technique [0002] With the improvement of people's requirements for drinking water quality, water purification systems are gradually entering the drinking water system of every household. At present, water purifiers on the market generally use reverse osmosis filter components, which can filter organic matter, colloids, bacteria, viruses and other impurities in raw water, especially for inorganic salts, heavy metal ions and other impurities. efficiency. Therefore, the reverse osmosis filter element assembly constitutes the core component of the water purifier, and the filtering effect of the water purifier is directly related to the filtering effect of the reverse osmosis filter element assembly. For the convenience of replacement and aesthetic considerations, many water purifiers on the market use disposable revers...

Problems solved by technology

Generally, a waterway conversion device is installed at the installation head of the filter element assembly to isolate and divert the water flow, but the existing waterway conversion device integrates multiple complex waterways into the same part, resulting in difficulty in mold release, low yield rate, and It is easy to block. In addition, during the spin-melting welding process of the shell, the shell will drive the internal waterway conversion device and the reverse osmosis filter element to rotate, and the mutual movement between the three will cause damage to the components or failure of the seal.
