A mining automatic explosion-proof water curtain device with dust suppression function

Abstract

An automatic explosion-proof water curtain device for mines with the function of dust suppression according to the present invention comprises rotating shafts arranged sequentially from the inside to the outside, the inner pipe and the outer pipe can be rotated, the rotating shaft and the inner pipe are welded and connected by welding pieces, and the outer pipe Set on the outside of the inner tube; the surface of the inner tube is provided with an atomizing nozzle and a water curtain opening, the atomizing nozzle is located on the side wall of the inner tube, and the water curtain opening is located on the upper part of the inner tube; the outer tube includes a liquid outlet, a waterproof sealing cover and a pressure The water supply pipe, the liquid outlet is arranged on the side wall of the outer pipe, and is arranged in cooperation with the atomizing nozzle of the inner pipe. The pressure water supply pipe and the waterproof sealing cover are respectively arranged at both ends of the outer pipe, and the rotating shaft is set through the waterproof sealing cover. Hit the panel, and the waterproof sealing cover is provided with a limiting part to realize the limited rotation of the rotating shaft. The device can greatly reduce the cost of installation and maintenance of the two types of equipment, and reduce the potential safety hazards caused by the failure to store water in the explosion-proof water bag in time. When the explosion occurs, the water curtain will be released automatically to isolate the explosion flame, control the scope of the disaster and reduce the disaster loss. .

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
