Description

Technical Field

[0001] The utility model relates to the technical field of dust filtering, in particular to a dust filtering device. Background Art

[0002] In the production work of factories and workshops, various basic materials (such as metal, wood, chemical raw materials, etc.) are processed, ground, cut, sprayed, etc., so that the solid particles generated are suspended in the air, resulting in a large amount of dust and particles floating in the air. The generation of dust will have a negative impact on the health of workers and production efficiency. Inhaling dust in the air will damage the human respiratory system and lungs, leading to a series of health problems, which will not only affect production, but also reduce environmental quality and employee health. At that time, dust filtering becomes a necessary measure for factories and workshops.

[0003] However, the dust particles in factories and workshops vary in size. When common filters filter dust in the air, they usually use the machine's own settings to filter dust. The design structure of the dust filter may only be suitable for one filtration process, and these filters may only contain a single filter layer or filter medium and cannot perform multiple cycles of filtration. Due to the large difference in dust particle size, if only one filter plate is used for filtration, it may not be possible to completely filter out fine particles, affecting the filtration efficiency and thus failing to achieve the expected filtration effect. In addition, this filtration method can easily lead to blockage of the machine, affecting its service life and reducing filtration efficiency. Utility Model Content
