A coal gangue overburden separation layer grouting equipment for sealing fissures

Abstract

The application relates to the technical field of grouting equipment, in particular to coal gangue overburden separation layer grouting equipment for sealing fissures, which comprises a mounting plate, a grouting mechanism is arranged on the upper end face of the mounting plate, an outer shell is arranged outside the grouting mechanism, the lower end of the outer shell is fixedly installed on the mounting plate, a cover plate is arranged on the upper end of the outer shell, and a fixing assembly is arranged between the upper end of the cover plate and the outer shell. The double-layer heat preservation structure of the outer shell cooperates with an electric heating plate to stably maintain the slurry storage and conveying environment temperature, slurry coagulation caused by low temperature is avoided, the stirring blades in the slurry storage tank continuously stir under the driving of a stirring motor, stratified precipitation of components in the slurry is prevented, the slurry is ensured to be always in a uniform flow state, the filling compactness of small separation layer fissures is improved, the problem that traditional equipment cannot completely seal due to slurry flowability reduction is solved, and the overburden structure stability is enhanced.
