Description

Technical Field

[0001] The utility model relates to the field of air filtration, and specifically to a multi-stage air filtration device. Background Art

[0002] Air filters are a type of equipment widely used in industrial, household and commercial places. They can remove dust, bacteria, viruses, pollen, odor and other impurities in the air to improve air quality. Current air filters are difficult to replace and clean. In addition, although some multi-stage filtration devices can achieve multi-stage filtration, the air flow rate will slow down after each stage of filtration, resulting in inefficient filtration speed. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an air multi-stage filtering device.

[0004] The technical solution adopted by this utility model:

[0005] A multi-stage air filtering device comprises a filter box 1, a filter box 2 and a filter box 3, wherein the filter box 1, the filter box 2 and the filter box 3 are arranged equidistantly from left to right, the left and right side walls of the filter box 1, the filter box 2 and the filter box 3 are fixedly connected with connecting pipes, ventilation pipes are inserted between the opposite connecting pipes, the connecting pipe on the left side of the filter box 1 is inserted with an air inlet pipe, and the connecting pipe on the right side of the filter box 3 is inserted with an air outlet pipe, the tops of the filter box 1, the filter box 2 and the filter box 3 are opened, and a movable cover is arranged at the top opening of the filter box 1, the filter box 2 and the filter box 3, and filter cores are movably inserted in the interiors of the filter box 1, the filter box 2 and the filter box 3, and the filter cores are respectively matched with the interiors of the filter box 1, the filter box 2 and the filter box 3, and a handle is fixedly connected to the top of the movable cover, and fans are arranged on the inner walls of the air inlet pipe, the air outlet pipe and the two ventilation pipes.

[0006] Beneficial effects of the utility model:

[0007] The utility model adopts three filter boxes, each of which is equipped with a filter element, realizing multi-stage filtration, which can better remove impurities and odors in the air. The top of the filter element is provided with a movable cover, which is convenient for pulling it out from the filter box for replacement or cleaning. The operation is simple and quick. By arranging fans in the air inlet pipe, the air outlet pipe and the ventilation pipe, the air circulation speed can be accelerated and the filtering efficiency can be improved.

[0013] like Figure 1-4 As shown: filter box 1, filter box 2, and filter box 3 are arranged equidistantly from left to right, the left and right side walls of filter box 1, filter box 2, and filter box 3 are fixedly connected with connecting pipes 4, and ventilation pipes 5 are inserted between the opposite connecting pipes 4, the connecting pipe 4 on the left side of filter box 1 is inserted with an air inlet pipe 6, and the connecting pipe 4 on the right side of filter box 3 is inserted with an air outlet pipe 7, the top of filter box 1, filter box 2, and filter box 3 is open, and a movable cover 11 is set at the top opening of filter box 1, filter box 2, and filter box 3, and a filter core 8 is movably inserted inside the filter box 1, filter box 2, and filter box 3, respectively. The filter core 8 matches the inside of filter box 1, filter box 2, and filter box 3, respectively, and a handle 9 is fixedly connected to the top of the movable cover 11. The air inlet pipe 6, the air outlet pipe 7 and the inner side walls of the two ventilation pipes 5 are all provided with fans 10. Fan 10 is a suction fan.

[0014] The air is discharged from the outlet pipe 7 after passing through the filter box 1, the filter box 2, and the filter box 3, and the fan 10 is used to draw the air from the inlet pipe 6, and the air is discharged from the outlet pipe 7 after being filtered by three filter elements 8 at multiple stages. The air passes through the filter box 1, the filter box 2, and the filter box 3, and the wind speed is increased after passing through the fan 10. The fan 10 is used to speed up the air circulation speed of the two ventilation pipes 5 and the outlet pipe 7, and improve the filtering efficiency. When the filter element 8 needs to be replaced, it can be pulled out from the filter box by the handle 9, and the replacement and cleaning are more convenient. The utility model only protects the mechanical part, and the functions related to it realized by the software control part are not within the protection scope of the utility model.
