Description

Technical Field

[0001] The utility model relates to the technical field of oil net dust filter sealing, in particular to a sealing structure for an oil net dust filter. Background Art

[0002] The oil mesh dust filter is a device used to filter dust and impurities in the air and is widely used in various ventilation systems. Its working principle is mainly to capture and filter dust particles in the air through the oil mesh, so as to achieve the purpose of purifying the air. When the oil mesh dust filter is not in use, in order to slow down the oxidation rate of the oil mesh installed inside and reduce the entry of dust, it is often necessary to use a sealing structure to close the vents at both ends. In the existing patent application with application number CN202220714516.2, a sealing structure of an oil mesh dust filter is proposed. When the sealing structure is installed on the oil mesh dust filter, it is necessary to rotate the circular metal cover plate several times so that the first internal threaded annular sleeve is screwed on the first external threaded annular sleeve. However, this process is relatively cumbersome, resulting in low efficiency in installing the sealing structure on the oil mesh dust filter, so it needs to be improved. Utility Model Content
