Specific embodiment
Referring to the drawings and the present invention is described in detail in embodiment.
Referring to Fig. 1, a kind of external High Pressure Spray for Dust Suppression automatic control device of coalcutter by water supply tank 1, high-pressure hydraulic pump 6, becomes
Frequency controller 7, semi-circular high-pressure sprayer 11, hydraulic pressure detection sensor 12, coal dust detection sensor 14 and high-pressure water pipeline group
At 17 rear of roller of coalcutter 16 is arranged in semi-circular high-pressure sprayer 11, which is provided with the high pressure nozzle of multiple multi-angles
13, multiple high pressure nozzles 13 are mounted on the upper surface of semi-circular high-pressure sprayer 11 by different angle, make the high-pressure water mist sprayed can
Fig. 2 is seen to form the semi-circular high pressure waterwall 15(of ruler thickness around roller 17), semi-circular high pressure waterwall 15 is wrapped in roller
Around 17, reach pressure dust-laying effect.Also, semi-circular high-pressure sprayer 11 is mounted on behind roller 17, has no effect on coal mining
The operation of machine 16 and other equipment.
Automatic water compensating valve 2 is housed on the water inlet pipe of water supply tank 1, mine water enters water supply tank 1 by automatic water compensating valve 2, from
Dynamic water compensating valve 2 protects liquid level in water tank to reach optimum level of water always；Equal hydrophone 3, silt resistance plate washer 4, filtering are equipped in water supply tank 1
Cover 5, equal hydrophone 3 connect water inlet pipe, and equal water pipe 3 makes the water in water supply tank 1 that liquid level be kept not fluctuate steadily, on protection liquid level is steady
It rises or secondary raise occurs in decline, the impurity such as silt when must exempt from into water in mine water.Silt hinders plate washer 4 for three-level setting, mud
Silt in mine water point three is intercepted resistance shelves by sand resistance plate washer 4, it belongs to primary coarse filtration, mainly intercepts big grain silt and its
Its impurity, it is that resistance shelves silt drifts about with the fluctuation of water, it is therefore an objective to provide impure least clean water for high-pressure hydraulic pump 6
The probability of the obstruction of high pressure nozzle 13 is effectively reduced in source.Filter mantle 5 is connected to the water inlet pipe port of high-pressure hydraulic pump 6, and filter mantle 5 is
Afterbody fine filtering, all impurity for crossing silt resistance plate washer 4 are finally all filtered out by filter mantle 5.
High pressure water pipeline includes three sections, is high-pressure hose 8, metal high-pressure pipe 9 respectively, can perturb metal high-pressure pipe 10, gold
Belong to high-voltage tube 9 to be fixed on coalcutter ontology, metal high-pressure pipe 9 is connect by high-pressure hose 8 with high-pressure hydraulic pump 6；Gold can be perturbed
Belong to 10 one end of high-voltage tube and connect metal high-pressure pipe 9, the other end connects semi-circular high-pressure sprayer 11, can perturb metal high-pressure pipe 10
As the swing arm of coalcutter is swung up and down, high-pressure water is provided for semi-circular high-pressure sprayer 11.High-pressure hydraulic pump 6, high-pressure hose
8, metal high-pressure pipe 9, metal high-pressure pipe 10, semi-circular high-pressure sprayer 11 and high pressure nozzle 13 can be perturbed constitute closed height
Pressure pipeline, the high pressure water come out from high-pressure hydraulic pump 6 are transmitted to high pressure nozzle 13 through pipeline, most spray ruler thickness through nozzle sets afterwards
Semi-circular high pressure waterwall 15.
17 rear of roller of coalcutter 16 is equipped with coal dust detection sensor 14, and the water inlet end of semi-circular high-pressure sprayer 11 is set
Have a hydraulic pressure detection sensor 12, coal dust detection sensor 14 and hydraulic pressure detection sensor 12 respectively with the frequency conversion control of high-pressure hydraulic pump 6
Device 7 processed is electrically connected.Coal dust detection sensor 14 is mainly the concentration of the coal dust around detection roller 17 when mining, then will be dense
Degree variation feeds back to frequency-variable controller 7, automatically turns down water supply pressure by frequency-variable controller 7 when detecting that Dust Concentration is low,
When detecting that Dust Concentration is high by 7 automatic adjustment height water supply pressure of frequency-variable controller, so that hydraulic pressure be made to follow coal dust dense automatically
Degree changes and reaches automatic energy saving depositing dust.Pressure on the semi-circular high-pressure sprayer 11 of 12 real-time detection of hydraulic pressure detection sensor
Power, when hydraulic pressure reaches setting value, system issues alarm signal when (upper limit value), and personnel's high pressure nozzle 13 is reminded to have clogging,
It needs to clear up in time.High-pressure hydraulic pump 6 controls revolving speed by frequency-variable controller 7, makes pressure piping protection in certain constant pressure
Under, realize automatic constant pressure control.
A whole set of electric control system realizes automated closed-loop control and automatic alarm to depositing dust by various sensors, is not necessarily to people
Work intervention.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to change with equivalent structure made by description of the invention and accompanying drawing content, it is intended to be included within the scope of the present invention.
