An air purification device with variable flow rate

Abstract

The invention relates to an air purification device with variable flow rate, which comprises an air box main body. The main body of the air box is divided into a filter chamber and a diversion chamber, wherein a filter adjustment mechanism is arranged in the filter chamber, and a diversion adjustment mechanism is arranged in the diversion chamber. , an exhaust pipe is provided on the main body of the air box corresponding to the side wall of the guide cavity; wherein the filter adjustment mechanism includes a filter bag assembly and a closure assembly; the filter bag assembly includes a filter bag assembly, and the closure assembly includes a movable Closed cylinder, adjust the opening of the filter bag by adjusting the position of the closed cylinder to adjust the filter area of ​​the filter bag, and at the same time, the array of movable deflectors is set in the diversion chamber, and the flow rate and exhaust pressure can be realized by changing the distance between the deflectors Adjustment; the present invention uses a set of mechanisms that can change the cross-sectional area of ​​the filter bag, and utilizes the characteristic that the air will flow preferentially in the direction of lower flow resistance, and realizes the change of the air filtration speed without changing the power of the fan, and the response is quick .

Description

technical field [0001] The invention relates to air purification equipment with variable flow rate, belonging to the field of air purification equipment. Background technique [0002] Under different production efficiencies of the factory, the exhaust air volume will also be different, especially at night, when production is reduced, the exhaust air volume will be reduced, and the wind pressure will also be reduced. At this time, it is not necessary to participate in the filtration surface of the entire filter equipment. Filtration, so the cross-sectional area of ​​the filter surface participating in the filter flow path can be reduced at this time, so that the air can be circulated and filtered faster; while the traditional flow rate is simply to reduce the flow rate of the fan or enter the air into the air purification equipment. Although this method can reduce the load of the filter equipment, the low air flow rate not only cannot reduce the load of the filter equipment, ...
