Description

Technical Field

[0001] The utility model relates to the field of oil net dust filters, in particular to a combined oil net dust filter. Background Art

[0002] An oil-mesh dust filter is a device used to filter particulate matter in the air. It is usually composed of multiple layers of metal wire mesh, which have different mesh sizes and are treated with oil and placed in a metal frame. When air flows through the metal wire mesh, the dust will be stuck due to the adhesion of the oil and thus be filtered out. During the use of the oil-mesh dust filter, when dust falls on the oil mesh, the adhesion of the oil mesh will be reduced. Therefore, the more dust falls on the oil mesh, the worse the adhesion of the oil mesh will be. Therefore, as time goes by, the dust filtering effect of the oil mesh will also deteriorate. Therefore, a combined oil-mesh dust filter is needed to solve the above problems, thereby reducing the burden of the oil mesh and improving the dust filtering effect of the oil-mesh dust filter.
