Pulse bag type dust collector with cloth bag joint protective sleeve

Abstract

The invention provides a pulse bag type dust collector with a cloth bag joint protective sleeve. The lower end of a shell body is connected with an ash bucket. An ash discharging valve is arranged atthe bottom of the ash bucket. An air inlet is further formed in the ash bucket. The space in the shell body is divided into an upper air purifying chamber and a lower filtering chamber by the patternplate. A filter bag is arranged in the filtering chamber. A communicating hole is formed in the pattern plate. The filter bag is fixed on the pattern plate through a cloth bag joint penetrating through the communicating hole. A purified air outlet is formed in the air purifying chamber. A blowing pipe externally connected with an air source is arranged in the air purifying chamber. A first end ofthe cloth bag joint protective sleeve is located on the inner side of a cloth bag joint and matched with the cloth bag joint in shape, and a second end of the cloth bag joint protective sleeve bypasses an upper end opening of the cloth bag joint and is connected with the pattern plate outside the cloth bag joint. According to the pulse bag type dust collector with the cloth bag joint protective sleeve, reverse blowing airflow can be prevented from being directly blown to the cloth bag joint in the dust cleaning process, and acting force acting on the cloth bag joint protective sleeve cannot act on the cloth bag joint again.

Description

technical field [0001] The invention relates to the technical field of machine dust removal, in particular to a pulse bag dust collector with a bag joint protective cover. Background technique [0002] Since the pulse bag filter came out in the 1950s, it has been widely used at home and abroad, and has been continuously improved. It has made great progress in purifying dusty gases. Large size, small footprint, high purification efficiency, reliable operation, simple structure, and small maintenance. The dust removal efficiency can reach more than 99%. It is a mature and relatively complete high-efficiency dust removal equipment. [0003] The pulse bag filter is mainly composed of shell, filter bag, ash hopper, ash discharge device, bracket and pulse cleaning system. When the pulse bag filter works normally, the dusty gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, some of the coarser dust particles fall into the ash hopper due t...

AI Technical Summary

Problems solved by technology

[0006] In the pulse bag dust collector with the bag joint protective cover of the above structure, a protective cover is embedded in the bag joint, and the protective cover can prevent the blowback air from blowing directly at the bag joint during the dust cleaning process, which greatly reduces the pressure on the bag joint and the dust collector. The mutual friction between the flower plates prolongs the service life of the bag joint, but there is still room for improvement in the structure
