Vibration device for bag-type dust collector

Abstract

The invention discloses a vibration device for a bag-type dust collector. The vibration device comprises a machine body, wherein a plurality of filter elements are arrayed in the machine body, a dustcleaning control system is arranged in the machine body located above the filter elements, a dust hopper for storing dust is arranged in the machine body located below the filter elements, impact bodies are fixedly arranged at bottoms of the filter elements separately, fixing rods are separately arranged in the machine body located below the filter elements, impact sleeves for encircling the impact bodies are separately arranged at the ends, close to the filter elements, of the fixing rods, a plurality of driving devices for controlling the sloshing of the fixing rods are arranged at internalpositions, close to the fixing rods, of the machine body and comprise a plurality of driving motors fixedly arranged in the machine body, connecting discs are fixedly arranged on output shafts of thedriving motors, connecting levers are hinged to parts, far away from centers of circle, of the connecting discs, and the ends, far away from the connecting discs, of the connecting levers are vertically fixed to the fixing rods separately. According to the bag-type dust collector, through a simple structure, dust of positions, far away from the dust cleaning control system, of the filter elementscan be successfully cleared out.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a vibration device used in a bag filter. Background technique [0002] The bag filter 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; Enter the main body of the dust collector and pass 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; After a large amount of dust, the compressed air is released through the dust removal control system, that is, the pulse valve is quickly opened and closed, and the pulse air flow is released into the filter element. The deformation and vibration of the filter element shake off the dust adhered to the surface of the filter eleme...

Problems solved by technology

[0003] However, in some larger bag filters, the filter element is set longer, and the dust removal control system is generally set on the top of the filter assembly. When the pulse air flow is released to the filter element to deform and vibrate the filter element, it is easy to shake off the dust. During the process, the smaller the pulse air flow that the filter element is exposed to away from the dust removal control system, the smaller the vibration and deformation of the filter element away from the dust removal control system, which is not enough to shake off the dust adhering to the surface of the filter element, thereby reducing the dust loss. The reusability of the filter element affects the next dust removal effect
