Abstract
The utility model relates to a novel dust reduction spraying device for the extraction of a thin coal bed. The existing dust reduction spraying device for coal mines is mostly required to be additionally provided with equipment such as an additional electrical device or a high pressure air device as power, thereby not only having a complicated structure, but also being inconvenient to control. The novel dust reduction spraying device for the extraction of the thin coal bed comprises a hollow shaft, a shaft sleeve, spraying rods and spraying heads. The novel dust reduction spraying device for the extraction of the thin coal bed is characterized in that the upper end of the hollow shaft stretches into the shaft sleeve, and further is provided with a bearing; a water seal is arranged between the hollow shaft and the shaft sleeve; the lower end of the hollow shaft is provided with multiple ports; one end of each spraying rod is connected into the port; the other end of each spraying rod is connected with the spraying head; the quantity of the spraying rods and the spraying heads is corresponding to that of the ports; the axes of the spraying heads and the axis of the hollow shaft mutually form noncoplanar lines; the top part of the shaft sleeve is fixedly arranged; and a water inlet is formed in the shaft sleeve. The novel dust reduction spraying device for the extraction of the thin coal bed is small in size, low in weight, simple in structure and low in manufacturing cost, thereby being widely applicable for the dust reduction in the environments with high dust concentration, particularly being applicable for the dust reduction during the construction of underground coal mines.
Description
Technical field
The utility model relates to a kind of atomization mechanism, particularly the novel spraying device for removing dust of a kind of thin seam mining.
Background technology
Pit mining is blown out in the digging operation, and coal, rock are pulverized in blasting process and the fine particle that forms forms respectively coal dust and rock dirt.The dust that swims enters the human body respiration organ with people's breathing, and wherein larger grit is delayed at and is easy in the respiratory tract be excreted, and particle diameter can both enter the human lung and cause all kinds of pneumoconiosis less than 5 microns the large section of dust; The coal dust that generates in coal seam, most colliery has explosivity, and these coal dusts are suspended in when reaching finite concentration in the air, and under the high temperature heat source effect, coal dust can be blasted; For gas and high prominent mine, use the electrical control spraying to be subjected to the condition influence such as concussion of blasting, cause easily electric fixtures " to lose quick-fried ".Existing dust falling in coal mining atomization mechanism needs the equipment such as optional equipment electrical installations or pressure-air device as power more, complex structure not only, and be not easy to control.Therefore need the novel spraying device for removing dust of a kind of thin seam mining simple in structure, that be convenient to control.
The utility model content
The technical problems to be solved in the utility model is the defects that how to overcome prior art, provides a kind of thin seam mining novel spraying device for removing dust.
For solving the problems of the technologies described above, the novel spraying device for removing dust of this thin seam mining comprises hollow shaft, axle sleeve, spray lance and fog-spray nozzle, described hollow shaft upper end is stretched in the axle sleeve, and be provided with bearing, and water-stop between hollow shaft and the axle sleeve, the hollow shaft lower end is provided with a plurality of interfaces; Described spray lance one end and access interface, the other end connect fog-spray nozzle, and spray lance, fog-spray nozzle are corresponding one by one with the quantity of interface; The axis of fog-spray nozzle and the axis of hollow shaft be different surface beeline each other; Described axle sleeve top is fixed, and which is provided with water inlet.
So design, this device is fixed in back, current enter axle sleeve by water inlet, the hollow shaft of flowing through and spray lance are by fog-spray nozzle ejection, because fog-spray nozzle axis and hollow shaft axis different surface beeline each other, so the reaction force F one of current decomposites one surely along the tangential component F/ of fog-spray nozzle rotational trajectory, under the effect of this power, overcome the rotational resistance f of hollow shaft, rotating spraying, depositing dust.
As optimization, be provided with the internal expanding spring between bearing and the axle sleeve and the spring that rises outward.So design is fixed in bearing on the axle sleeve, and bearing promotes the rotation of hollow shaft.
As optimization, described spray lance is hollow straight tube.So design is simple in structure, easy to make.
As optimization, described spray lance is hollow bent pipe.So design, resistance to water-flow is little.
The novel spraying device for removing dust volume of this thin seam mining is little, lightweight, simple in structure, cheap, has to be active in one's movements, and output hydraulic pressure is large, covers the characteristics such as full section, and installation, easy and simple to handle, safeguards easily.Be widely used in the depositing dust of high dust concentration environment, be particularly useful for the depositing dust in the underground construction of colliery.
