FILTER AND AIR-CONDITIONING WATER SYSTEM FLUSHING AND FILTERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/060564
Kind Code:
A1
Abstract:
A filter (8) and an air-conditioning water system flushing and filtering device. The filter (8) comprises: a mounting pipe (81) provided with a water inlet, a back flushing inlet and a back flushing outlet; and a filtering mechanism, comprising a first filtering assembly (807) and a second filtering assembly (808), wherein the first filtering assembly (807) comprises a first positioning ring (8072), a first filter screen (8071) and a first sealing sheet (8073), the second filtering assembly (808) comprises a second positioning ring (8082), a second filter screen (8081) and a second sealing sheet (8083), the first positioning ring (8072) and the second positioning ring (8082) are respectively fixed to an inner pipe wall of the mounting pipe (81), and the first filter screen (8071) and the second filter screen (8081) are respectively movably arranged in the first positioning ring (8072) and the second positioning ring (8082). During back flushing, the first sealing sheet (8073) and the second sealing sheet (8083) deform to generate a thrust on a water body located between the first filter screen (8071) and the second filter screen (8081), so that impurities adsorbed near surfaces of the first filter screen (8071) and the second filter screen (8081) fall off and are dissolved into the water body, and are discharged from the back flushing outlet, thus the filtering capability of the first filter screen (8071) and the second filter screen (8081) can be periodically recovered without disassembly for cleaning. The air-conditioning water system flushing and filtering device comprises: a mounting box (1), wherein the filter (8) is arranged in the mounting box (1); a water inlet pipe (4); a connecting guide pipe (7); a water storage tank (3); a bearing pipe (302) and a back flushing pipeline (6); and a drainage pipe (5).
