Abstract
The utility model discloses an electronic automatic spray dust remover which comprises a control circuit, wherein the control circuit is arranged in an anti-explosion box, and is connected with a spray head through an anti-explosion electromagnetic valve which is connected with a water supply pipe through a check valve; the control circuit is connected with an infrared sensor. The utility model realizes two control modes of semi-automation and automation by switching a micro switch arranged in the anti-explosion box; the spray time and the delay time are optionally adjusted in six gears; the working performance is stable and reliable; the design concept conforms to safety production requirements of coal mines.
Description
Technical field
The utility model relates to a kind of big lane of coal mining underground work, down-hole system of producing coal that is applied to and passes loading point, i.e. the automatic electronic spraying firing dust device of belt feeder, machine lane chain metal plate machine, tippler.
Background technology
The harm of mine dust mainly shows: 1, mine dust pollutes work situation, has reduced the visibility in production place, for example, whenever goes out coal car one time, will fly upward by grit in the big lane, influences efficiency and handling safety; 2, workers with long time operation in mine dust, suck a large amount of mine dusts after, the lighter causes respiratory inflammation, weight person can cause pneumoconiosis, has a strong impact on health and life-span; 3, the coal dust in the mine dust has combustibility, runs into extraneous burning things which may cause a fire disaster and is easy to cause fire, and coal dust can also cause explosion accident, causes tremendous loss.
The improvement of mine dust becomes the emphasis in the coal mining work, for realizing mine synthesis dust prevention, need reach the networking of underground mine water supply system water, the installation codeization of dustproof facilities, and big lane purifies distinguished and admirable automation.
For preventing flying upward of mine dust, generally use the spray for dust suppression method.Present spraying facility all is to lean on gate valve control manually, does not possess science, technical, opens gate valve and nobody shows any interest in, cause hypervolia, the main haulage roadway mire, track skids, make coaler reduce speed, influenced production efficiency and tunnel environmental sanitation.If belt conveyer and tippler injection flow rate are too much, belt feeder is skidded, the heat that rubbed between belt and the carrying roller, temperature sharply rises, and the initiation fire accident will influence safety in production easily, causes unnecessary economic loss.
The utility model content
The utility model technical issues that need to address just are to overcome in the prior art defective of spray for dust suppression manually, and a kind of automatic electronic spraying firing dust device is provided
For addressing the above problem, the utility model adopts following technical scheme:
The utility model automatic electronic spraying firing dust device comprises control circuit, and described control circuit is installed in the armored cassette and is connected with fog-spray nozzle by explosion-proof solenoid valve, and explosion-proof solenoid valve connects feed pipe by a check valve.
Control circuit described in the utility model is connected with infrared sensor.
Explosion-proof solenoid valve described in the utility model is the 127V explosion-proof solenoid valve.
The utility model automatic electronic spraying firing dust device, it realizes semi-automatic, automatic two kinds of control modes by the microswitch that switching is arranged in the armored cassette.Spray time and delay time divide six grades random adjustable.
The utility model semi-automatic work principle is: it is made up of infrared sensor control circuit, 127V explosion-proof solenoid valve, is static at ordinary times, does not spray.During by sensor, sensor sends instruction as personnel and vehicle, and control circuit drives the magnetic valve spraying, and the spraying time-delay stops to wait after a few minutes automatically.
The automatic operation principle of the utility model is: it is made up of control circuit, 127V explosion-proof solenoid valve, and after power on circuitry, control circuit drives magnetic valve spraying, time-delay, spraying, according to the circulation spraying automatically of certain cycle.
The utility model stable and reliable working performance, design concept meet the Safety of Coal Mine Production requirement.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model automatic electronic spraying firing dust device comprises control circuit 1, and described control circuit is installed in the armored cassette 2 and is connected with fog-spray nozzle 4 by 127V explosion-proof solenoid valve 3, and explosion-proof solenoid valve connects feed pipe 6 by a check valve 5.
Control circuit described in the utility model is connected with infrared sensor 7.
Be provided with the microswitch 8 that connects infrared sensor and control circuit in the utility model armored cassette.
Control circuit described in the utility model is general custom circuit, as 8 single chip microcontroller EM78P156E of CMOS type that can adopt instrument grand electronics corporation in Taiwan to produce.The double base infrared sensor LHi968 that infrared sensor can adopt Shenzhen multipole technological development Co., Ltd to produce.
