Description

A kind of hydraulic support Multifunctional automatic spraying device for reducing dust
Technical field
The utility model relates to a kind of multifunctional spray device for reducing dust, specifically a kind of hydraulic support Multifunctional automatic spraying device for reducing dust for colliery down-hole combined mining working chalk dust removing.
Background technology
Dust pollution in coal mine roadway is serious, and especially fully-mechanized mining working equipment is even more serious when broken coal coal breakage, affects underground work environment, does not meet safe mass standardization requirement.
At present, mine fully mechanized coal face face mechanization degree is high, and coal cutting and to put the speed of coal very fast easily produces a large amount of coal dusts, and the staff of fully mechanized coal face is produced to certain harm; Dust Concentration runs into naked light when very high or high temperature easily produces gas explosion, harm operating personnel's safety and the national heavy losses of property.On market, fully mechanized coal face support spraying device for removing dust is by complicated electronic induction equipment and electrical control equipment, to realize fully mechanized coal face fall monitoring in frame process or induction and realize auto spraying mostly, but, the most complexity of installing of these products, difficult in maintenance, and also cost of investment is higher.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic support Multifunctional automatic spraying device for reducing dust, to solve existing hydraulic support spraying system operation inconvenience, difficult in maintenance, the problem that spray effect is poor.
Scheme of the present utility model is as follows: a kind of hydraulic support Multifunctional automatic spraying device for reducing dust, comprises spray valve, water inlet pipe, outlet pipe, falls frame signal pipe, rises frame signal pipe, feed tube and liquid back pipe;
Water inlet pipe, outlet pipe are connected with spray valve respectively, and the other end of water inlet pipe is connected with stop valve, and the other end of outlet pipe connects spray lance, and shower nozzle is set on spray lance;
Fall frame signal pipe, rise frame signal pipe and be connected with spray valve respectively, fall the frame signal pipe other end and be connected with feed tube by threeway, rise the frame signal pipe other end and be connected with liquid back pipe by threeway.
Described spray valve is also provided with one-way interfaces and nozzle.
Described spray valve is provided with more than two.
The nozzle of described spray valve is connected by interlock injection spray pipe with the one-way interfaces of next spray valve.
The utility model is without any need for supporting facility, can directly access the original hydraulic system of hydraulic support, the hydraulic system of support of take is operation power, to realize opening and closing spray valve, realize support and move between frame and frame interlock and window and automatically carry out atomizing de-dusting when putting coal, dust-laying effect is obvious.And, from practical problem, fundamentally solve the problem that mine dust is large, improve underground work environment, reaching quality standards requirement.Both can reduce labor strength, also save water supply volume.
Accompanying drawing explanation
Fig. 1 is the structural representation of the single spray valve of the utility model.
Fig. 2 is the connection diagram of a plurality of spray valves of the utility model.
Fig. 3 is that the utility model is followed the fundamental diagram of coal-winning machine while spraying at random.
The specific embodiment
Below in conjunction with accompanying drawing to new novel being further described of this practicality.
A Multifunctional automatic spraying device for reducing dust, comprises spray valve 6, water inlet pipe 7, outlet pipe 1, falls frame signal pipe 8, rises frame signal pipe 4, feed tube 2 and liquid back pipe 3; Water inlet pipe 7, outlet pipe 1 are connected with spray valve 6 respectively, and the other end of water inlet pipe 7 is connected with stop valve 10, and the other end of outlet pipe 1 connects spray lance 5, on spray lance 5, shower nozzle is set; Fall frame signal pipe 8, rise frame signal pipe 4 and be connected with spray valve 6 respectively, fall frame signal pipe 8 other ends and be connected with feed tube 2 by threeway, rise frame signal pipe 4 other ends and be connected with liquid back pipe 3 by threeway.
Described spray valve 6 is also provided with one-way interfaces G and nozzle A; Described spray valve 6 is provided with more than two; The nozzle A of described spray valve 6 is connected by interlock injection spray pipe 9 with the one-way interfaces G of next spray valve.
The utility model in the specific implementation, interlock injection spray pipe 9 is connected to realize interlock spraying between frame with the one-way joint G of undercarriage spray valve, or linkage tube is connected with the spray valve one-way joint of lower pack support by flow divider and realizes many interlock sprayings, spray lance is fixed on the position that produces dust concentration maximum, the interlock one-way joint of last hydraulic support is blocked with plug, realizes interlock spraying between single frame spraying or frame.
As need, follow coal-winning machine and realize spraying, as shown in Figure 3, operating valve 12 and one-way lock 13 are incorporated in support spraying system, the operating valve 12 that utilizes support falls frame signal pipe 8, rises frame signal pipe 4 access control system in parallel through an one-way lock 13 and spray valve 6, can, by signal pressure active feedback to spray valve 6, realize manual STOCHASTIC CONTROL spraying; If operating valve 15 is changed into autocontrol valve or machine control valve is arranged on the cut route of coal-winning machine, can realize with machine and automatically control spraying.
Although above the specific embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that manual contains yet, all should be within protection domain of the present utility model.
