Embodiment Construction
[0016] Install the device in the middle of the roof of the roadway at a distance of 5-10 meters from the front of the blasting working face of a coal mine, and use the top nut to connect with the roof bolt. The compressed air and water supply hoses are respectively connected to the air and water direct connections corresponding to the spray from the roadway air and water pipe tees. The amount of air and water intake is manually adjusted through the valve, so that after the confluence of wind and water, a mist is formed, which plays the role of sprinkling water and reducing dust in the early stage after firing. For head-on spray use, see figure 2 .
[0017] For further dust removal, tees are installed in the air and water pipes every 100m in the roadway. Connect the Fengshui hose from the tee to connect with the Fengshui linkage device. The device is installed on the side anchor rods on both sides of the roadway, and the full-section spray sees image 3 . Turn on the head...

The invention discloses a spraying dust-suppression device based on air and water pressure linkage, and belongs to homemade designed and manufactured dust and smoke suppression devices applied to blasting driving faces. The spraying dust-suppression device mainly comprises a steel pipe, a steel plate, a deformed bar, two joints and a hose. Specifically, as the body of the device, the steel pipe with the diameter being 108mm and the length being 600mm are plugged from two sides, and the internal space of the steel pipe serves as an air and water mixing area of the device. A plurality of holes with diameter phi being 4mm are drilled in the surface of the steel pipe to achieve spraying; a hole with diameter phi being 20mm is drilled at one plugged end, the steel pipe with diameter phi being 20mm and the length being 150mm is welded to the hole so as to facilitate feeding of air and water. The two joints are welded to the steel pipe and respectively connected with an air pressure pipe anda water supply pipe. In application of the spraying dust-suppression device, an air pressure pipe valve is turned on and then a water supply pipe valve is turned on to form air and water pressure linkage; under the air and water pressure linkage, a spraying effect covering the full cross section of a tunnel is achieved. Spraying range can be adjusted by adjusting air pressure and water supply pressure.
Description
technical field [0001] The patent of the present invention is a device for sprinkling water to reduce dust and eliminate smoke in coal mines. The device overcomes the shortcomings of previous dust reduction equipment. The traditional sprinkler dust suppression device is only powered by water pressure, the spray distance is short, the coverage section is small, and the atomization effect is not good. And long-term use is easy to cause nozzle blockage, affecting the spray effect. The wind-water linkage sprinkling and dust suppression device adopts the combination of wind pressure and water pressure, which can greatly improve the effect of dust reduction and smoke elimination in the well. Background technique [0002] A large amount of coal dust and toxic and harmful gases are likely to be produced after blasting in the blasting working face of underground coal mines, and the coal dust accumulated in the roadway is also likely to cause explosion accidents. Toxic and harmful g...
