Problems solved by technology

In addition, the traditional filter cartridge installed in the dust collector is short so that the exhaust fan can effectively blow back the filter cartridge; and the filter cloth on the filter cartridge is PS (polystyrene) polymer coating, fiber filter material Folded into a large number of pleats and glued on the circular iron net, when the material is isolated on the surface of the filter material and falls on the pleats, most of the material on the upper part of the filter cartridge remains in the original place after being blown back by compressed air, unable to fall to the bottom of the box
When the use environment is soda ash and other materials that are easy to agglomerate, they will accumulate in the folds for a long time, and without manual cleaning, a large area of ​​hard lumps will form. Under the action of compressed air blowback vibration, the filter material is easily crushed Tearing causes damage to the filter barrel

Abstract

The invention discloses a pulsed cartridge filter, which comprises a filter body, an air compressor, a plurality of filter cartridges arranged in the filter body, a plurality of pulse blowing pipes, a pulse signal generator and a reducing valve, wherein each pulse blowing pipe is provided with a pulse solenoid valve; the pulse blowing pipes are communicated with the filter cartridges in a one-to-one correspondence manner and communicated with the reducing valve by the air compressor; and the pulse signal generator sends signals to the pulse solenoid valves successively to control the pulse blowing pipes where the pulse solenoid valves are located for blowback. With the adoption of the technical scheme, the pulsed cartridge filter has the benefits that the successive time of the pulse signal generator is prolonged and controls the pulse blowing pipes for the blowback, so as to allow dust in the filter to drop into a dust hopper at the bottom of the filter body by the action of appropriate air force. The fact that the dust cannot be gathered in the filter body and still floats onto the filter cartridges as the air compressor conducts the blowback on the filter cartridges simultaneously to result in a too small blowback force is avoided.

Description

technical field [0001] The invention relates to a dust collector, in particular to a pulse filter cartridge dust collector. Background technique [0002] In the field of dust removal applications in space environments, the use of dust collectors has become very common. However, during the use of the traditional dust collector, the exhaust fan connected to the dust collector blows back the inside of the dust collector to achieve the effect of blowing off the dust. In the back blowing process, the exhaust fan is required to continuously blow the air inside the dust collector, which is not conducive to cost saving. In addition, the traditional filter cartridge installed in the dust collector is short so that the exhaust fan can effectively blow back the filter cartridge; and the filter cloth on the filter cartridge is PS (polystyrene) polymer coating, fiber filter material Folded into a large number of pleats and glued on the circular iron net, when the material is isolated o...
