Description
Technical field
The utility model belongs to the device that a kind of fully-mechanized mining working is eradicated coal dust producing.
Background technology
Due to raising and the application of coal mining do mechanization operation, coal mine output and driving size significantly promote, and make underworkings work plane produce great coal dust, and its concentration is big very fearful, and the increasing of underground ventilating ability makes coal dust propagate fartherly.Coal dust directly endangers respiratory system, gives that workman is healthy causes serious health hazards, runs into spark strong blast will occur when coal dust gathers some and concentration, brings about great losses to workman's life security and national wealth.
The way of at present dedusting: have water spray, curtain, exhausting, but the effect playing is very low.
Summary of the invention
Technical problem to be solved in the utility model is to provide the device that a kind of fully-mechanized mining working is eradicated coal dust producing, compared with prior art, the utility model is provided with the high-pressure spray gun that directly sprays to coal cutting point, and coal cutting point is sealed, thereby reaches the object of radical cure coal dust.
For achieving the above object, the technical program is as follows:
Fully-mechanized mining working is eradicated a device for coal dust producing, comprises mole, and described mole is provided with at least one towards the giant of development machine head coal cutting point.
Further, described giant is provided with two to three, and along circle ring array centered by coal cutting point respectively, giant injection direction is perpendicular to the axis direction through development machine head.
Further, described mole is provided with the screening arrangement at driving point by the forward end seal of mole; Screening arrangement and four sides, tunnel and development end form enclosure space.
Further, the surrounding that described screening arrangement contacts with tunnel adopts flexible material.
Further, the edge of screening arrangement is fixed with accessory plate, and the marginating compartment of accessory plate is provided with spring, and a side and the spring of spring are tied intrinsic flexible material.
Further, at least one side of described screening arrangement is provided with the side door of enclosure space in the same way.
Further, described screening arrangement middle part is provided with transparent isolation window, and transparent isolation window is provided with rain brush.
Further, described screening arrangement be provided with ventilation opening, in gravity vent, be provided with the outer suction pipe road communicating with enclosure space.
Further, in described enclosure space, be provided with atomization mechanism.
Operating principle of the present utility model and the course of work are as follows:
The utility model arranges high-pressure spray gun on development machine, and this high-pressure spray gun directly sprays to the coal cutting point of mole, on the one hand the current that eject of high-pressure spray gun can and enter into along groove inner rigid that spray gun cannot be sprayed onto by the heading end spin axis of mole and start and break-up point occurs to tunnel, the generation point that has directly stoped peak discharge coal dust, on the other hand, giant directly sprays coal cutting point, can be along with rotating into inside except above-mentioned, also have small part water splash to form water smoke, steam or cascade, further at generation coal dust point, reach the effect of dedusting.
Visible, water spray site is directly in the place that coal dust occurs, coal dust before not flying upward, coal dust is drenched to processing, make in its automatic stirring and absorption, coal dust becomes pulpous state coal slime, than present, treat that coal dust carries out various processing methods to coal dust again after forming and compares, the manner is more directly effective, and has reduced the use amount of water.The quantity of spray site can be selected as required.
On mole, be provided with screening arrangement, coal cutting point can be enclosed in the space in screening arrangement and four sides, tunnel and development end, thereby have effectively stoped the escape that remains coal dust, further strengthen dust removing effects.
With respect to existing water curtain, this screening arrangement is portable structure, and workman is positioned at beyond enclosure space always, and coal dust amount is few.
The form of original cascade, only can stop 30% dust, most of dust all escapes out, and existing eject position, spray site add screening arrangement, greatly reduce coal dust amount, one class of handy at least four mouth mask of workman of original Dust Capacity per tour, and can reach the effect without mouth mask now.
The surrounding of screening arrangement adopts flexible material, and four limits of screening arrangement can better be pasted again with the four sides in tunnel, prevent that space from appearring in screening arrangement and tunnel, the escape that coal dust carries out from gap.
Be provided with side door can better facilitate driving operating personnel enter in the space of sealing, inspection driving face working condition and be convenient to the maintenance to mole front end.
Screening arrangement adopts transparent material, such as implosion guard Steel material, and coordinates rain brush, follows the carrying out of driving exploitation and the work of rain brush, and staff can well observe driving and the working condition in enclosure space outside the space of sealing.
A ventilation opening is set above screening arrangement, on ventilation opening, is provided with the pipeline of outer suction with enclosure space, the air in enclosure space can be inhaled outward, thereby finally reach the effect of the thorough Ex-all of residue coal dust.
