Technical Field

[0001] The utility model relates to the technical field of overburden strata separation grouting, in particular to a cloth bag dust collector which is convenient for quick disassembly and assembly in overburden strata separation grouting. Background Technique

[0002] The overburden strata separation grouting technology is mainly applied to the ground pressure control and environmental protection in the process of coal mine exploitation. When the strata above the goaf of the coal mine are fractured and displaced due to the loss of support, the phenomenon of strata separation will occur between the strata; the grouting technology is to inject slurry (usually cement slurry or other chemical slurry) into these separated strata zones. Through the diffusion, filling and consolidation of the slurry, the separated strata zones are re-cemented, so as to achieve the purpose of strengthening the strata, controlling the ground pressure and preventing ground settlement.

[0003] During the overburden strata separation grouting process, it is necessary to expand the grouting port. A drill is needed during the expansion process, and a large amount of dust will be generated during the work process. Therefore, a cloth bag dust collector is needed to filter the dust in the air. The internal filter cloth bag of the existing cloth bag dust collector is usually fixed by bolts, and the installation and disassembly are relatively inconvenient, reducing the work efficiency, and improvement is needed.
