Problems solved by technology

[0002] As we all know, human life is inseparable from water. However, with the rapid development of society, the lag of environmental protection work has caused different degrees of pollution to people's drinking water. Therefore, people have invented water purification products, such as: Chinese patent 02272876.7 "Ultra-polymer composite membrane water purifier", "ceramic membrane water purifier" in 200520065862.9, "a household water purifier using multi-stage filter element" in 200320118259.3, "household hollow fiber ultrafiltration membrane water purifier" in 200520026901.4 etc., especially the invention of hollow fiber ultrafiltration membranes, ceramic membranes and other filter elements has brought the water purification industry to a new level and provided clean drinking water for the society. However, these filters need to be cleaned or replaced regularly during filtration and purification. Use brings trouble, the Chinese patent 95238672.0 "water purifier with energy-storage backwashing mechanism" and the "oxygenation self-cleaning terminal household filter" of 01215527.6 can solve the self-cleaning problem, but the structure is complicated and the operation is inconvenient. Moreover, The cost is also higher, and it is inconvenient to popularize and promote

Embodiment Construction

[0013] With reference to Fig. 1, Fig. 2, Fig. 3 is the first kind of embodiment of a kind of filter self-cleaning device of the present invention: the jet channel adopts the structural representation of U-shaped pipe, and it is made up of water inlet pipe R, shell 1, filter core 2, The jet channel 3, the jet device 4, the drain faucet 5, and the water purification faucet 6 are composed. The outer casing 1 is made of stainless steel and sealed in a cylindrical shape. The top of the cylinder is threaded and connected to the water purification faucet. Two through holes are processed at the bottom of the cylinder. The two ends of the jet water channel 3 are fixed by argon arc welding, and the connection between the cylinder top, the bottom and the cylinder body adopts the method of argon arc welding, but the bottom of the cylinder needs to be welded after the filter element 2 is installed and combined with the jet water channel; Core 2 adopts a conventional plastic hollow fiber wat...

Abstract

The present invention relates to a self-cleaning method for filter and its device. It is characterized by that it utilizes jet flow suction force, and at the same time of using domestic water makes the filter interior produce negative pressure, and utilizes the negative pressure to reverse flush the filtering element, so that the various dirts adsorbed on the outer wall of filtering element can be reversely sucked out and can be discharged out together with domestic water. Its device includes the following several portions: water inlet tube, outer shell, filtering element, jet flow water channel, jet flow device, water discharge tap and clean water tap.

Description

Technical field: [0001] The invention relates to a water purification device, in particular to a filter self-cleaning method and its device, which belong to the technical field of drinking water purification. The method of the invention is most suitable for self-cleaning of microporous filtration membranes such as hollow fiber membranes and ceramic membranes cleaning. Background technique: [0002] As we all know, human life is inseparable from water. However, with the rapid development of society, the lag of environmental protection work has caused different degrees of pollution to people's drinking water. Therefore, people have invented water purification products, such as: Chinese patent 02272876.7 "Ultra-polymer composite membrane water purifier", "ceramic membrane water purifier" in 200520065862.9, "a household water purifier using multi-stage filter element" in 200320118259.3, "household hollow fiber ultrafiltration membrane water purifier" in 200520026901.4 etc., esp...
