Description

Technical Field

[0001] The utility model relates to the technical field of filter fans, in particular to a plate-type filter fan which is convenient for replacing filter components. Background Art

[0002] The plate filter fan is a commonly used air purification equipment, and its core component is the plate filter. The main function of this filter is to effectively intercept particulate impurities, such as dust and particulate matter, when the fluid passes through, so as to ensure the cleanliness of the output fluid. As the filtering process continues, more and more impurities will accumulate on the plate filter, which will cause the filtering resistance to gradually increase, thus affecting the ventilation volume or fluid flow of the fan. Therefore, regular replacement or cleaning of the filter assembly is an important measure to maintain the efficient operation of the plate filter fan.

[0003] The existing Chinese patent with announcement number CN217233853U discloses a primary and secondary efficiency filter air box, including a filter box, the filter box including an air inlet and an air outlet, the cavity in the filter box is divided into a primary efficiency filter chamber, an air supply chamber and a secondary efficiency filter chamber from the air inlet to the air outlet, a support frame is provided inside the air supply chamber, a blower is installed on the top of the support frame, four groups of extended bolts are provided inside the support frame, the surface of the extended bolts below the support frame is covered with pads, the inside of the air supply chamber below the pads is covered with threaded seats, and the surface of the extended bolts below the pads is covered with support springs.

[0004] Although the above scheme realizes multi-stage and efficient filtration of gas by the primary and medium efficiency filter fan box and improves the gas filtration effect, the filter fan is inconvenient to disassemble and assemble the filter, and the bag-type medium efficiency filter is still a traditional fixing method. At the same time, the gap between the plate filter and the groove frame will affect the actual filtration effect and affect the use. Therefore, it does not meet the existing needs. In this regard, we propose a plate filter fan that is easy to replace the filter component. Utility Model Content
