Mining automatic explosion-proof water curtain device with dust lowering function

Abstract

The invention provides a mining automatic explosion-proof water curtain device with a dust lowering function. The device comprises a rotary shaft, a rotatable inner pipe and an outer pipe, wherein therotary shaft, the rotatable inner pipe and the outer pipe are sequentially arranged from inside to outside. The rotary shaft and the inner pipe are connected through soldering lug soldering, and theouter pipe sleeves the inner pipe. Atomizing nozzles and a water curtain opening are formed in the surface of the inner pipe, the atomizing nozzles are arranged on the side wall of the inner pipe, andthe water curtain opening is formed in the upper portion of the inner pipe. The outer pipe comprises a liquid outlet, a waterproof sealing cover and a pressure water supply pipe. The liquid outlet isformed in the side wall of the outer pipe and cooperates with the atomizing nozzles of the inner pipe, the pressure water supply pipe and the waterproof sealing cover are arranged at the two ends ofthe outer pipe correspondingly, the rotary shaft penetrates through the waterproof sealing cover, the end portion of the rotary shaft is horizontally connected with a hit panel, the waterproof sealingcover is provided with a limiting part, and limiting and rotating of the rotary shaft are achieved. By means of the device, the cost of mounting equipment and maintenance equipment can be greatly reduced, potential safety hazards caused by the fact that water is not stored in an explosion-proof water bag in time are reduced, a water curtain is automatically released during explosion, explosion flames are prevented from propagating, the disaster range is controlled, and disaster losses are reduced.

Description

Technical field: [0001] The invention belongs to the field of coal mine safety production, and in particular relates to an automatic explosion-proof water curtain device for mines with the function of reducing dust. Background technique: [0002] In the process of coal mine production, coal dust and gas explosions are potential safety hazards that seriously restrict production and threaten the lives and health of coal miners. Therefore, in each coal mine roadway, equipment such as dust-reducing atomizers and explosion-proof water bags are installed. Form a water curtain to block the spread of explosion flames in the roadway. [0003] Today's dust suppression atomizer and explosion-proof water bag are two separate devices that only have separate functions. Dust-suppressing atomizers have the problem of fewer nozzles and poor dust-suppressing effect; while explosion-proof water bags also need to store water regularly and quantitatively to ensure their normal functions, so it...

AI Technical Summary

Problems solved by technology

Dust-suppressing atomizers have the problem of fewer nozzles and poor dust-suppressing effect; while explosion-proof water bags also need to store water regularly and quantitatively to ensure their normal functions, so it is necessary to check the status of the equipment frequently, which increases the workload of coal miners. workload, and failure to store water in the flameproof water bag as planned can create even greater safety hazards
