Abstract
The utility model discloses an automatic dust removal control system for a coal mine, which comprises a power supply circuit, a coal dust density sensor, an electric control valve and a PLC control system; the coal dust density at each point in the air is measured through the coal dust density sensor; the coal dust density signals detected by the coal dust density sensor are analyzed and processed through the PLC control system, and control commands of sprinkling manner and sprinkling amount of the relevant dust removal media are obtained; and the commands are input to the electric control valve and executed, so as to realize full automatic control of the entire process, and reduce labor intensity of working personnel; meanwhile, the medium dose can be reasonably controlled, so as to guarantee dust removal effect, reduce cost, and save energy.
Description
Technical field
The utility model relates to automatic control system, particularly a kind of colliery dedusting automatic control system.
Background technology
Each link of coal mining all can produce a large amount of coal dusts, and the explosion accident of coal dust and gas happens occasionally especially, and dustproof, depositing dust is healthy closely related with mine operation personnel not only, especially An Quanshengchan important leverage.Driving face, transportation and passageway, belt transportation system etc. all are the main dust seedbeds under the coal mine, how can dustproof effectively and dedusting be carried out in these dirt seedbeds, have become the important investigation index of safety in production.The dust pelletizing system of prior art is generally manually controlled by operating personnel, manually opened when needing, manual-lock when not required, also can in the entire job process, spray incessantly or spray in case of necessity, coal dust is skewness in air, and the spray concentration of dedusting medium is difficult to guarantee the dust removing effects of each point, simultaneously, continual spray has caused a large amount of wastes of the energy when improving operating cost.
The utility model content
In view of this, the utility model provides a kind of colliery dedusting automatic control system, can adjust the emitted dose of dedusting medium according to the coal dust CONCENTRATION DISTRIBUTION, improve efficiency of dust collection, realize the robotization control of dust pelletizing system simultaneously, reduce labour intensity and production cost, energy savings.
Dedusting automatic control system in colliery of the present utility model comprises feed circuit, coal dust concentration sensor, motor-operated control valve and PLC control system, described coal dust concentration sensor signal output part is connected with the signal input part of PLC control system, PLC control system instruction output end is connected with motor-operated control valve instruction input end, motor-operated control valve links to each other with the control circuit of dust pelletizing system media outlet, and described feed circuit are electrically connected with coal dust concentration sensor, motor-operated control valve and PLC control system respectively.
Further, described feed circuit comprise power circuit and intrinsically safe circuit, and described power circuit is electrically connected with motor-operated control valve and PLC control system, are electrically connected by intrinsically safe circuit between power circuit and the coal dust concentration sensor.
The beneficial effects of the utility model: dedusting automatic control system in colliery of the present utility model, measure the coal dust concentration of each point in the air by the coal dust concentration sensor, by the PLC control system coal dust concentration signal of the detection of coal dust concentration sensor is analyzed and the steering order of handling and obtain relevant dedusting medium spray mode and spray flux, instruction is input to motor-operated control valve and carries out, whole process realizes full-automatic control, the labour intensity that reduces a staff, simultaneously, the medium consumption obtains rationalizing control, reduces cost and energy savings when ensureing dust removing effects.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure:
The colliery dedusting automatic control system of present embodiment, comprise feed circuit, coal dust concentration sensor 1, motor-operated control valve 2 and PLC control system 3, the signal output part of coal dust concentration sensor 1 is connected with the signal input part of PLC control system 3, the instruction output end of PLC control system 3 is connected with the instruction input end of motor-operated control valve 2, motor-operated control valve 2 links to each other with the control circuit of dust pelletizing system media outlet, and feed circuit 4 are electrically connected with coal dust concentration sensor 1, motor-operated control valve 2 and PLC control system 3 respectively.When the utility model is achieved in that operation, waiting to remove a plurality of nozzles that link to each other with the dust pelletizing system media feed system of dirt pits distribution, the coal dust concentration sensor is fixedly set in the position of the contiguous ejiction opening of nozzle, start the PLC control system, the coal dust concentration sensor is measured the coal dust concentration of nozzle each point, the PLC control system is analyzed and the steering order of handling and obtain relevant dedusting medium spray mode and spray flux the coal dust concentration signal of the detection of coal dust concentration sensor, instruction is input to motor-operated control valve and carries out, thereby realize the full-automation control of whole spray process, wherein, feed circuit, PLC control system and coal dust concentration sensor are prior art; The coal dust concentration sensor can also be infrared light formula sensor, during application, be distributed in tunnel or other main dust source point, when the staff walks about in the tunnel, the infrared ray that infrared light transducer[sensor induction human body sends because of heat also sends the coal dust distribution signal of staff through the place, signal sends jeting instruction through the processing of PLC control system and to the motor-operated control valve that is positioned at this point, realizes directed targetedly dedusting.
As further improvement, in the present embodiment, feed circuit, coal dust concentration sensor, motor-operated control valve and PLC control system are the flameproof and intrinsic safety structure, ensure the safety of dedusting operation.
As further improvement, in the present embodiment, feed circuit comprise power circuit 5 and intrinsically safe circuit 6, power circuit 5 is electrically connected with motor-operated control valve 2 and PLC control system 3, be electrically connected by intrinsically safe circuit 6 between power circuit 5 and the coal dust concentration sensor 1, intrinsically safe circuit can further improve the security performance of system.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
