Bag-type dust collector with prepositioned cyclone separator

Abstract

The invention discloses a bag-type dust collector with a prepositioned cyclone separator. The bag-type dust collector comprises a machine body, wherein a plurality of filter elements are arrayed in the machine body, a dust cleaning control system is arranged in the machine body located above the filter elements, the filter elements arrayed along the vertical direction of the dust cleaning controlsystem form a set of filter assembly, a dust hopper for storing dust is arranged in the machine body located below the filter elements, upper ends of the filter elements are fixedly connected with corrugated pipes separately, the ends, far away from the filter elements, of the corrugated pipes are fixedly connected with the dust cleaning control system separately, auxiliary vibration devices are separately arranged on the filter elements and comprise connecting plates arranged on external walls of the filter elements close to middle-lower parts, the connecting plates are fixedly connected witha set of filter assembly simultaneously, telescopic springs are fixedly arranged at bottoms of the connecting plates, the ends, far away from the connecting plates, of the telescopic springs are fixedly connected with slipping working plates, the slipping working plates are arranged on the external walls of the filter elements in a slipping manner and are located below the connecting plates, anda driving device for controlling the telescoping of the telescopic springs is arranged on the dust hopper.

Description

technical field

[0001] The invention relates to air purification equipment, in particular to a bag dust collector with a pre-cyclone dust collector. Background technique

[0002] The bag filter of the pre-cyclone dust collector is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. It is generally composed of a dust collector host, a filter assembly and a dust removal control system; Composed of multiple filter elements, the gas enters the main body of the dust collector and passes through the filter element. At this time, the dust impurities in the gas adhere to the filter element, and the gas passes through the filter element to become clean gas and then is discharged, thus realizing the filtering of the gas; When a large amount of dust adheres to the filter element, through the dust removal control system, the compressed air is quickly opened and closed through the pulse valve, and the pulse air flow is released to enter the filter elem...
