Abstract
The invention discloses a spraying device for mines. The spraying device comprises a spraying cap, a main cavity and a gas inlet pipe. The spraying cap is cylindrical. The gas inlet pipe is fixed on the main cavity and communicated with the interior of the main cavity. The main cavity and the spraying cap are coaxial. The main cavity is inserted into the spraying cap and connected with the spraying cap in a threaded mode. A water passing pipeline is arranged in the main cavity. The front end of the main cavity is of a cone shape and is provided with a water outlet. The water outlet penetrates through an outlet in the end face of the spraying cap and extends out. Two protruding side lugs are arranged on the end face of the spraying cap. Each side lug is provided with a gas spraying pipe. The spraying device can isolate dust and harmful gas, and therefore harm to the human body from the mining environment can be remarkably reduced.
Description
Technical field
The present invention relates to a kind of dust removing down-hole equipment, specifically a kind of mine spray device.
Background technology
As everyone knows, colliery industry is the hotspot of occupational disease, coal-face under mine, during the high speed coal mining of mechanization and conveyer belt transport coal fast, a large amount of coal dusts is had to fly upward and coal gas and vapor permeation, along with tunnel air-flow flows string everywhere, pollute quite serious, underground labour's long-term operation can not be ignored the harm that health produces.On the other hand, the water resource that down-hole has is not enough, and directly can not spray with water, operator can not be with water conservancy project to do, and causes workman's black mud water from head to foot, directly has influence on coal miner life and health.At present, in China's major part underground coal mine working space, effective dust prevention and control facility is still lacked.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of mine spray device, it can intercept fleeing of dust and pernicious gas preferably, reduces the injury to human body.
For solving the problems of the technologies described above, mine spray device of the present invention, it is characterized in that comprising spray cap, main chamber and air inlet pipe, described spray cap is cylindric, described air inlet pipe is fixed on main chamber, described air inlet pipe is communicated with inside, main chamber, described main chamber is coaxial with spray cap, described main chamber is inserted spray cap inside and is connected with spray cap thread, water-filled pipe is provided with in described main chamber, front end, main chamber is taper and is provided with delivery port, this delivery port passes the outlet of spray cap end face and stretches out, described spray cap end face is also provided with picking up the ears of two projections, each pick up the ears on be equipped with air jet pipe, described air jet pipe through pick up the ears with spray cap inside be communicated with.
Described air inlet pipe is threaded with main chamber above.
More than one sealing ring is provided with above between described main chamber and spray cap.
After adopting such scheme, main chamber, spray cap constitute adjustable gas ejecting system, the system that they and delivery port constitute water, gas coordinates, water is after delivery port ejection, the gases at high pressure be ejected smash, and become the vaporific steam of large density, and this steam constitutes a stifled clean wall, by dust and pernicious gas isolation, thus significantly reduce the injury of mining environment to human body.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of atomization mechanism of the present invention.
Detailed description of the invention
As shown in Figure 1, mine spray device of the present invention, it is characterized in that comprising spray cap 1, main chamber 2 and air inlet pipe 3, described spray cap 1 is cylindric, described air inlet pipe 3 is fixed on main chamber 2, described air inlet pipe 3 is communicated with inside, main chamber 2, described main chamber 2 is coaxial with spray cap 1, described main chamber 2 is inserted spray cap 1 inside and is threaded with spray cap 1, water-filled pipe 4 is provided with in described main chamber 2, front end, main chamber 2 is taper and is provided with delivery port 5, this delivery port 5 passes the outlet of spray cap 1 end face and stretches out, what described spray cap 1 end face is also provided with two projections picks up the ears 7, each picking up the ears is equipped with air jet pipe 6 on 7, described air jet pipe 6 through pick up the ears 7 with spray cap 1 inside be communicated with.
Air inlet pipe 3 can adopt conventional multiple known method with the connected mode in main chamber 2, as being threaded, welding etc.More than one sealing ring 8 is provided with between main chamber 2 and spray cap 1.The external tapping of the water-filled pipe 4 of back cavity 2, the external tapping of air inlet pipe 3 all can adopt existing national standard interface.
During use, native system is divided into water route and gas circuit two systems, water is sprayed by delivery port 5 in the water-filled pipe 4 in main chamber 2, spray cap 1 is inner surrounds an inner space with main chamber 2, gas enters inner space then from two passage ejections from air inlet pipe 3, one is the air jet pipe 6 of picking up the ears on 7, another is the gap between delivery port 5 and spray cap 1 end face central outlet, when main chamber 2 is when spraying screw thread precession or back-out on cap 1, the gap that can change, thus have adjusted jet flow, thus regulate the size of water smoke.Water is after delivery port 5 ejection, and the gases at high pressure be ejected smash, and become the vaporific steam of large density, and this steam constitutes a stifled clean wall, by dust and pernicious gas isolation, thus significantly reduces the injury of mining environment to human body.
