Description
Technical field
The utility model relates to a kind of mine dedusting automatic sprayer, and for realizing driving face under coal mine, the timing in the tunnels such as coal-face spraying, flutters the harmful dust of catching in working environment by the particle water of high-pressure atomization, purify working environment.
Background technology
Because Working Environment of Underground Mine is comparatively severe, driving face, there is a large amount of dust in coal-face, human body respiration enters lung can cause the occupational diseases such as silicosis, health is caused to great infringement, although the counter-measures such as respirator have all been taked to be with such as staff in each mining area, but can not tackle the problem at its root, the side leakage of respirator and staff's the mode with mouth mask is incorrect etc., and reason makes dust-proof effect unsatisfactory, affect human body natural breathes simultaneously, do not meet the management of hommization, want to reduce the damage of working environment dust to human body, best scheme is the dust concentration reducing in working environment, purify working environment.
Although the measure of dust concentration in more existing reduction working environments at present, but still expect more efficiently mode and dust arrester more practical, that can be suitable for different application occasion.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, provide a kind of and especially can be applicable to non-transformer, only have the mine dedusting automatic sprayer in the workplace at airduct and water source, to for reducing dust concentration in working environment, the requirement that purifies working environment can obtain better effect.
The utility model is that technical solution problem adopts following technical scheme:
The design feature of the utility model mine dedusting automatic sprayer is:
It is the airtight water container consisting of casing and case lid that water tank is set; The inlet pipeline being communicated with external water source is connected with casing by water inlet snap joint, water feeding one-way valve and water inlet gate valve successively, and described water feeding one-way valve is towards water tank one side one-way conduction, and described intake gate valve opening is adjustable; Radiator drain road is connected with external atomization mechanism with outlet one way valve by water outlet snap joint successively; Muffler is set on case lid.
Floater controlled valve is set, and described floater controlled valve is while reaching capping height with ball float, to be unlatching, and is when setting lower limit height and closes with ball float;
Air intake control valve is set, with described floater controlled valve series connection, be arranged between the control port and air line of air intake control valve, with the unlatching of described floater controlled valve, control air intake control valve and will press wind access water tank, and make water tank remain normal pressure with the closing control air intake control valve of described floater controlled valve;
The design feature of the utility model mine dedusting automatic sprayer is also: it is rectangle or the circular cylinder body structure consisting of casing and case lid that water tank is set, and is pressed with " O " shape sealing ring between described casing and case lid.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model, without power supply, is used safety;
2, the utility model is realized timing automatic spraying, and good dedusting effect is stable and reliable for performance;
Noiseless when 3, the utility model is realized work;
4, the utility model is for the concrete condition of dust concentration in working environment, can intake the time interval that the flow adjustment of gate valve regularly sprays by adjusting, and effective guarantee working environment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: 1 water inlet snap joint, 2 water feeding one-way valves, 3 water inlet gate valves, 4 casings, 5 case lids, 6 strainers, 7 pressure ventilation pipe snap joints, 8 pneumatic control valves, 9 is " O " shape sealing ring, 10 ball floats are controlled air valve, 11 ball floats, 12 water outlet snap joints, 13 one way valves, 14 mufflers.
The specific embodiment
Referring to Fig. 1, in the present embodiment, the form of structure of mine dedusting automatic sprayer is:
It is the airtight pressure vessel that is filled with water consisting of casing 4 and case lid 5 that water tank is set; The inlet pipeline being communicated with external water source is connected with water tank by water inlet snap joint 1, water feeding one-way valve 2 and water inlet gate valve 3 successively, and water feeding one-way valve 3 is towards water tank one side one-way conduction, and water inlet gate valve 3 apertures are adjustable; Wherein, water feeding one-way valve 2, for controlling the flow direction of liquid, prevents the refluence of water tank cylindrical shell inner high voltage water, and water inlet gate valve 3 is for controlling fluid flow size.Radiator drain road is connected with external atomization mechanism with outlet one way valve 13 by water outlet snap joint 12 successively.Outlet one way valve 13 is except having back pressure effect spraying, avoid spraying simultaneously liquid water tank cylinder internal pressure with the poor less state of liquid level decline external and internal pressure under, liquid flows backwards in spray pipe, and muffler 14 is set on case lid 5.Water tank is when water inlet state, and muffler 14 outwards discharges floss hole is provided for water loading pressure raises, and plays the function of eliminating pneumatic noise when gas discharging.
Floater controlled valve 10 is set, and floater controlled valve 10 is while reaching capping height with ball float 11, to be unlatching, and is when setting lower limit height and closes with ball float 11; Lifting with ball float replaces mechanically actuated or electric power operation, safety and reliable in action.
Air intake control valve 8 is set, with floater controlled valve 10 series connection, is arranged between the control port and air line of air intake control valve 8, with the unlatching of floater controlled valve 10, control air intake control valve 8 and will press wind access water tank, as spraying power source; And with gas in the closing control air intake control valve 8 of floater controlled valve 10 and water tank with liquid level rising muffler 14 constantly discharge make water tank remain normal pressure, with floater controlled valve 10, control the commutation action of air intake control valve 8, and then the direction of change air intake control valve 8 eluting gas, realize the conversion of water inlet and spraying duty.
In concrete enforcement, it is to be welded by Q345 coiled sheet system that water tank is set, by casing 4 and case lid 5, formed, and be square or circular cylinder body structure, between casing 4 and case lid 5, be pressed with " O " shape sealing ring.
During use, external water source is by water inlet snap joint 1 access water tank, because being in low level, ball float 11 make floater controlled valve 10 for closing, air intake control valve 8 remains on left position and is failure to actuate, by strainer 6, through pressing the gases at high pressure from pressure air pipe of wind snap joint 7 accesses directly to discharge outside water tank through pneumatic control valve 8, in water tank, remain normal pressure and be operated under water state; When in water tank, liquid reaches the liquid level of setting, because the effect floater controlled valve 10 of ball float is opened, pneumatic control valve 8 is subject to air pressure control action to right position, make to enter water tank from the gases at high pressure of pressure air pipe, tank pressure is raise, water in water tank from the ejection of spraying joint, enters atomize under the effect of gases at high pressure; Along with the decline ball float of liquid level falls after rise under the effect of deadweight, pneumatic control valve 8 resets under the effect of spring, and water tank is got back to again into water state and completed a water spray circulation.
