Technical Field

[0001] The utility model relates to the technical field of oil mist filtering, in particular to a centralized oil mist filtering machine with automatic alarm display. Background Art

[0002] Centralized oil mist filter is a device used to remove oil mist in the working environment. It is usually used in mechanical processing, automobile manufacturing, petrochemical, food processing and other industries. This filter uses a centralized method to treat oil mist, which is highly efficient and environmentally friendly.

[0003] For example, an oil mist filter with publication number CN218687587U, when working, the maintenance door is closed to seal the filter cavity, and the air with oil mist enters the filter cavity from the air inlet, and is discharged from the air outlet after being filtered by the filter material. When the filter material needs to be replaced, the maintenance door is opened, and the filter material of the filter is replaced according to the processing of different products to purify the oil mist and atomized liquid, without the need to replace the entire filter. However, when replacing a single filter material, there are problems such as cumbersome disassembly and installation processes, and long time consumption. In addition, judging whether the filter material needs to be replaced by visually observing the degree of accumulation of particles on the filter material through the observation window is not accurate enough, and there are large subjective differences, which may lead to problems such as waste of filter material or untimely replacement. For this reason, a centralized oil mist filter with automatic alarm display is proposed for improvement. Utility Model Content
