Background technology
Dust causes following two kinds of harm at least under the coal mine: the one, influence the healthy of coal miner, and can cause ore deposit tuberculosis when serious; The 2nd, when dust concentration reaches capacity state, can set off an explosion, cause the ore deposit to ruin the people and die.In addition, dust causes severe contamination to the various facilities of coal excavation apparatus and down-hole, and, cause blurred vision (can degree of opinion reduce) because of dust suspends, thereby to cause maloperation, bury potential safety hazard.
The coal-winning machine of operation is the main dust source that causes Mine Dust on the fully-mechanized mining working under coal mine, therefore fully-mechanized mining working is implemented to follow the tracks of atomizing de-dusting and can suppress the dirt source effectively, improves subsurface environment.
Previously, mostly by manually-operated, operator's labour intensity is big for the atomizing de-dusting of fully-mechanized mining working, and atomizing de-dusting weak effect and safety are unreliable to be guaranteed.In recent years, automation has been realized to the spray for dust suppression of fully-mechanized mining working in nearly all colliery, thereby has greatly saved human input and improved dust-laying effect.Can be to this by the utility model patent notice of authorization CN201763370U confirmation that is not limited to, the technical contribution of this patent is that the water route of coal-winning machine auto spraying dust falling system is separated with the water route of coal-winning machine cooling motor, has solved can not pressurize and the problem of water shortage; Spray to producing dirt zone parcel pointedly by the nozzle specially used embodiment that is arranged on the coal-winning machine, or the like.Specifically can be referring to the 0026th section in the manual of this patent.
It is its shortcoming that above-mentioned patent scheme can not be implemented atomizing de-dusting in distinguished and admirable each zone downwards of coal-winning machine, therefore still has improved necessity, below the technical scheme that will introduce under this background, produce
Summary of the invention
Task of the present invention is to provide a kind of and can unites spraying automatically and use the coal-winning machine dirt source tracking atomizing de-dusting mechanism that the desirable water smoke curtain of formation is effectively contained in the dirt source causing in the coal mining process the distinguished and admirable zone enforcement downwards of coal mining ore deposit machine.
Task of the present invention is finished like this, atomizing de-dusting mechanism is followed the tracks of in a kind of coal-winning machine dirt source, comprise dirt source tracking depositing dust master control case, auto spraying depositing dust controller, light-operated receiving sensor, remote controller, electrical ball valve, water main, injection spray pipe and light-operated emission sensor, the atomizing de-dusting controller is followed the tracks of depositing dust master control case by communication cable and dirt source and is connected, light-operated receiving sensor is connected with auto spraying depositing dust controller by signal cable, remote controller is used to control the duty of auto spraying depositing dust controller, electrical ball valve connects on the pipeline of injection spray pipe, and injection spray pipe is connected with water main, and stop valve is installed on injection spray pipe, this stop valve in the position on the injection spray pipe between electrical ball valve and water main, light-operated emission sensor is arranged on the coal-winning machine, wherein: the dirt source is followed the tracks of depositing dust master control case and is connected with feed cable with auto spraying depositing dust controller, and electrical ball valve is connected with auto spraying depositing dust controller by signal control line.
Stop valve of the present invention is spherical stop valve.
Electrical ball valve of the present invention is the electronic ball valve of essential safe type.
Technical scheme provided by the invention is coordinated in the zone of fully-mechanized mining working can unite spraying automatically at the formation spraying point of the zone below the coal-winning machine wind direction, forms the water smoke curtain, and the dust that produces in the coal-winning machine coal mining process is effectively contained.
Description of drawings
Fig. 1 is a first embodiment of the present invention schematic diagram.
Fig. 2 is an application examples schematic diagram of the present invention.
Embodiment:
Ask for an interview Fig. 1, depositing dust master control case 1 is followed the tracks of in the dirt source that provided, one group of quantity is not subjected to illustrating the auto spraying depositing dust controller 2 of restricted number, be connected with feed cable 10 by communication transition cable 22 between the adjacent auto spraying depositing dust controller 2, and one at end is promptly followed the tracks of the adjacent auto spraying depositing dust controller 2 of depositing dust master control case 1 with the dirt source and is connected with dirt source tracking depositing dust master control case 1 by communication cable 21 and power supply transition cable 101.Each auto spraying depositing dust controller 2 sets an electrical ball valve 5 and a light-operated receiving sensor 3, wherein, electrical ball valve 5 is the electronic ball valve of essential safe type, be connected with 2 electrical controls of auto spraying depositing dust controller by signal control line 51, and light-operated receiving sensor 3 is connected with 2 electrical controls of auto spraying depositing dust controller by signal cable 31.Aforesaid electrical ball valve 5 connects on injection spray pipe 7, on injection spray pipe 7, be provided with drencher head 72(and also can claim fog-spray nozzle), injection spray pipe 7 is connected with water main 6, stop valve 71 is set on the pipeline of injection spray pipe 7, stop valve 71 is spherical stop valve, and it is between electrical ball valve 5 and the water main 6 in the position on the injection spray pipe 7.The remote controller of illustrating among the figure 4 is used for 2 remote manual controls of auto spraying depositing dust controller are controlled according to common practise.Light-operated emission sensor 8 is arranged on the coal-winning machine 9.
Application examples:
Provided dirt source and followed the tracks of depositing dust master control case 1, a N auto spraying depositing dust controller 2, a N light-operated receiving sensor 3, a N electrical ball valve 5 and N injection spray pipe 7, the notion of N described here is meant according to actual needs and does not have the specifically quantity of qualification.
At whole fully-mechanized mining working 20 n spraying point is set, begins to be arranged as in order 1#, 2#, x#~n# from air intake.When coal-winning machine 9 work moves to 1# promptly corresponding to the leftmost light-operated receiving sensor 3 of location status shown in Figure 2, give light-operated receiving sensor 3 by the light-operated emission sensor 8 that is provided with on the coal-winning machine 9 to signal, it is a leftmost auto spraying depositing dust controller 2 that signal is sent into 1#, signal is by after handling, by 1# auto spraying depositing dust controller 2 position signalling of coal-winning machine 9 is sent to the dirt source by the serial communication line and follow the tracks of depositing dust master control case 1, depositing dust master control case 1 is followed the tracks of behind the position signalling that receives coal-winning machine 9 in the dirt source, according to the predefined spraying point of uniting, the instruction of will spraying sends to corresponding auto spraying depositing dust controller 2, auto spraying depositing dust controller 2 is opened the electrical ball valve 5 that is connected with its electrical control according to the spraying order that comes from dirt source tracking depositing dust master control case 1, carries out auto spraying.
When coal-winning machine 9 was moved to the neutral gear position of light-operated receiving sensor 3 in working order, auto spraying depositing dust controller 2 received the spraying delay time and sprays, and delay time arrives, and spraying stops automatically.The rest may be inferred, and when coal-winning machine 9 was in the position of x# spraying point shown in Figure 2, system's executive mode was identical.Thereby be reduced in the dust that is produced in the coal mining process effectively
