Multipurpose top coal caving support with coal dust removing function

Abstract

The invention discloses a multipurpose top coal caving support with a coal dust removal function. A dust absorption mechanism is arranged at the lower end of a top beam, and external air can be drivenby a draught fan to enter an air inlet pipe, then filtered by a dust absorption bag and conveyed into an exhaust pipe, so that the dust content in the air is reduced, and dust removal and reducing are realized. A dust discharging mechanism is arranged on the face, facing one side of an air inlet pipe of the dust absorption bag, of every layer of dust removal filter screens, the dust discharging mechanisms can automatically discharge dust filtered on the dust removal filter screens, the dust discharging capacity is guaranteed, and the automatic dust discharging function is achieved. In the dust absorption process, the draught fan continuously works, a dust removal draught fan intermittently works so as to intermittently discharge the dust on the dust removal filter screens, the dust removal draught fan and the draught fan are arranged to enable the air speed in a dust discharging pipe to be at least 1.5 times larger than that in the dust absorption bag, and the dust discharge capacitycan be effectively improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a multi-purpose top-coal caving support with the function of removing coal dust. Background technique [0002] The hydraulic support is the main equipment of the comprehensive mechanized working face. It can reliably and effectively support and control the roof of the working face, isolate the goaf, maintain a safe underground working space, and realize the mechanized movement of the mining face and its related equipment. The bracket cooperates with the shearer, the flexible conveyor and the trough transfer machine to form a comprehensive mechanized equipment for the mining face, thus creating conditions for high-yield, high-efficiency and safe production in the underground mining of coal mines. For the top-coal support, the front portion of the top-coal support base is provided with a front slide, that is, a front slide, and the rear portion is provided with a rear sl...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing technology, a multi-purpose caving support with coal dust removal function is proposed, which solves the problem that when the caving support is placed inside the mine, during the mining process of the coal seam inside the coal mine, A lot of dust is often mixed in the air, and ordinary filter equipment is easily blocked by a large amount of dust
