The utility model provides a convenient to use, safe and reliable's air -operated controller's pulse jetting deashing system. The utility model discloses a with the continuous pneumatic pilot valve of pressure differential signal of air supply, its characterized in that: the pneumatic pilot valve of pressure differential signal links to each other with main gas bag, is provided with two outputs on the main gas bag, and an output links to each other through the little gas bag pulse instrument that moves of the same breath, and another output passes through the air pulsing valve and links to each other with the jetting pipe, pneumatic pulse instrument's output is continuous with the control end of air pulsing valve.
Description
Technical field
The utility model relates to deduster technology, particularly relates in coal mine roadway and the pulse jetting deashing system of the pneumatic control of explosive deathtrap.
Background technology
In coal mine roadway, near pick face, dust humidity is large, and be the operating mode of hazardous explosion prone, after the filter core of dust arrester adsorbs dust, is difficult to clear up dangerous again, especially can the process of respirable dust all be difficult to effectively be solved always.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of easy to use, the pulse jetting deashing system of safe and reliable pneumatic control.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises the pressure difference signal pneumatic pilot-valve that same source of the gas is connected, it is characterized in that: pressure difference signal pneumatic pilot-valve is connected with main gas bag, main gas bag is provided with two outputs, one output is connected with air-pulse gauge by little gas bag, and another output is connected with injection tube by Pneumatic impulse valve; The output of described air-pulse gauge is connected with the control end of Pneumatic impulse valve.
The beneficial effects of the utility model: 1, the utility model produces by air-pulse gauge the keying that the pulse of compressed air signal set controls Pneumatic impulse valve, thus realizes the function of blowing pressurized air, completes jetting deashing action.
2, the utility model is provided with pressure difference signal pneumatic pilot-valve, can control, decrease compressed-air actuated consumption according to the pressure reduction of dust arrester to source of the gas, and avoids the generation of excessive deashing phenomenon.
3, soot cleaning system of the present utility model can whole-process automaticly complete, and also can manually control separately Pneumatic impulse valve, convenient maintenance and malfunction elimination.
4, all control elements of soot cleaning system of the present utility model and executive component are by compressed air as the energy, root reduce the danger producing blast.
5, deashing system of the present utility model can expand according to specification of equipment and complex structure situation, can multiple Pneumatic impulse valve be connected in parallel on the output of pulse signal mouth of an air-pulse gauge, also can multiple stage air-pulse gauge in parallel, also can control by two kinds of method compound uses, the quantity controlling mouth in theory can infinite expanding, and conveniently realize many valves Parallel Control, control reliably not crash.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be air-pulse gauge in accompanying drawing, 2 be injection tube, 3 be Pressure gauge for Pneumatic impulse valve, 4 is main gas bag, 5,6 be pressure-reducing valve, 7 be filter, 8 be pressure difference signal pneumatic pilot-valve, 9 be pressure tap, 10 be discharging valve, 11 be little gas bag, 12 be filtering pressure reducing valve, 13 for stop valve.
Detailed description of the invention
The utility model comprises the pressure difference signal pneumatic pilot-valve 8 that same source of the gas is connected, it is characterized in that: pressure difference signal pneumatic pilot-valve 8 is connected with main gas bag 4, main gas bag 4 is provided with two outputs, one output is connected with air-pulse gauge 1 by little gas bag 11, and another output is connected with injection tube 2 by Pneumatic impulse valve 3; The output of described air-pulse gauge 1 is connected with the control end of Pneumatic impulse valve 3.
Filter 7, pressure-reducing valve 6 and Pressure gauge 5 is provided with between described pressure difference signal pneumatic pilot-valve 8 and main gas bag 4; Filtering pressure reducing valve 12 and stop valve 13 is provided with between described little gas bag 11 and air-pulse gauge 1.
Discharging valve 10 and pressure tap 9 is provided with bottom described main gas bag 4; The sewage produced in main gas bag 4 can be discharged in time, and the utility model whether fault can be detected by pressure tap 9.
When the utility model uses, pressure difference signal pneumatic pilot-valve 8 detects that dust arrester filter core (not shown) place pressure diminishes, when pressure reduction changes, source of the gas is that main gas bag 4 is inflated, an output of main gas bag 4 sends pulse signal by air-pulse gauge 1, pulse signal controls Pneumatic impulse valve 3 opening and closing, the pressure air of main another output of gas bag 4 is sprayed by the injection tube 2 on Pneumatic impulse valve 3, form air pulse, filter core is cleared up, omnidistance action is to be carried out automatically, without the need to personnel's manual operation, easy to use; Further, whole process all uses compressed air as the energy, and security is good, the danger that can not blast.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
