Air purification equipment with variable flow speed

Abstract

The invention relates to air purification equipment with the variable flow speed. The equipment comprises an air box main body. The interior of the air box main body is divided into a filtering cavityand a flow guiding cavity. A filtering and adjusting mechanism is arranged in the filtering cavity. A flow guiding and adjusting mechanism is arranged in the flow guiding cavity. An exhausting pipe is arranged on the side wall, corresponding to the flow guiding cavity, of the air box main body. The filtering and adjusting mechanism comprises a filtering bag assembly and a sealing assembly. The filtering bag assembly comprises a filtering bag assy assembly. The sealing assembly comprises a movable sealing cylinder. By adjusting the position of the sealing cylinder, the opening degree of a filtering bag is adjusted, and thus adjusting of the filtering area of the filtering bag is achieved. Meanwhile, flow guide sheets capable of moving are arranged in the flow guiding cavity in an array manner, and by changing the distance among the flow guide sheets, the flow speed and exhausting pressure can be adjusted. According to the equipment, by means of a set of mechanisms capable of changing the sectional area of the filtering bag, the characteristics that air preferably flows in the direction with low flow resistance is utilized, on the premise of not changing power of a fan, change of air filtering speed is achieved, and responding is rapid.

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, ...
