Description

Technical Field

[0001] The utility model relates to the technical field of oil net dust filters, in particular to an oil net dust filter with good dust filtering effect. Background Art

[0002] The oil-mesh dust filter is a highly efficient dust removal device, which is widely used in the fields of industrial production and environmental protection. It can capture and filter dust particles in the air through a special oil-mesh structure, thereby keeping the air clean and pure. The core component of the oil-mesh dust filter is the oil mesh, which is composed of multiple layers of fine metal mesh or synthetic fiber mesh, and the surface is coated with special lubricating oil. When the air containing dust passes through the oil mesh, the dust particles are adhered to the mesh surface by the lubricating oil, and the clean air flows out through the mesh holes;

[0003] Most of the existing oil mesh filters have a single-layer filter element structure inside to intercept and filter dust particles in the air, such as the Chinese utility model patent disclosed by publication number CN214469161U: a civil air defense oil mesh filter. This application pulls the push rod to move the latch pin out of the arc groove, and uses the compression spring to push the latch pin into the arc groove to fix and release the filter. It is easy to operate and disassemble, but only unilaterally realizes the convenience of disassembly and assembly of the filter. Since it is a single-layer filter element, dust in the air will accumulate in the filter element when filtering the air, so that the filter element needs to be disassembled and cleaned after using it for a period of time, which cannot effectively improve the dust filtering effect of the filter element and extend the cleaning cycle of the filter element.

The dust filter box 1 located in the middle position inside the positioning seat A4 is fixedly installed with a fixing rod 12, and a limiting block 13 is fixedly installed at the lower end of the fixing rod 12. The dust filter box 1 located between the two positioning seats B5 is also fixedly installed with a guide plate 11 on both sides, and the guide plate 11 is inclined at forty-five degrees. The two positioning seats C10 are used to set the air entering the dust filter box 1.

[0023] like Figure 2-Figure 5 As shown, a filter element B19 is inserted between the two positioning seats C10, and the lower end of the filter element B19 is installed at the lower end of the dust filter box 1 by fixing screws. The bottom plate 8 is L-shaped, and a telescopic groove 16 is provided in the connecting column 9. Two mounting grooves 17 are also provided on the outer side of the telescopic groove 16.
