Surface type reverse osmosis membrane filter element

Abstract

The invention belongs to the technical field of drinking water purification, and concretely relates to a surface type reverse osmosis membrane filter element. The filter element comprises a central tube and a filtering module; the bottom of the central tube is provided with a purified water outlet; the filtering module is located at the outer ring of the central tube, the filtering module is usedfor filtering water, and the filtering module comprises an inner filter membrane, an outer filter membrane, first rolling pillars, second rolling pillars and a sleeve; the inner filter membrane is located at the outer ring of the central tube, the inner filter membrane and the central tube are connected by a support, and a group of the first rolling pillars is uniformly distributed on the outer ring of the inner filter membrane; the outer filter membrane is located at the outer ring of the inner filter membrane, and a group of the second rolling pillars is connected to the inner ring of the outer filter membrane; and the second rolling pillars and the first rolling pillars are arranged in a staggered manner. The filter element has the advantages of simple structure, convenience in operation, improvement of the quality of purified water through double filtration of the inner filter membrane and the outer filter membrane in the filtering module, and cleaning of impurities accumulated onthe inner wall through squeezing and jittering the filter membranes by the first rolling pillars and the second rolling pillars.

Description

technical field [0001] The invention belongs to the technical field of drinking water purification, in particular to a surface type reverse osmosis membrane filter element. Background technique [0002] China's water purifier industry has a history of more than 30 years. As water resources have been seriously polluted in recent years, diseases and hazards caused by water pollution have occurred frequently. Healthy and safe drinking water has attracted more and more attention. As a result, people's awareness of healthy drinking water has also increased. Water purifiers are now generally recognized by many people. With the improvement of the per capita economic level and the maturity of water purifier technology, water purifiers are being accepted by more and more families and have gradually entered people's daily lives. Therefore, the market demand is very large, and under the huge market prospect, the number of water purification enterprises is growing like mushrooms after ...
