Description
Technical field
The present invention relates to dust removing down-hole of coal mine apparatus field, specifically, the present invention relates to under-well bi-directional linkage sprayer.
Background technology
Mine Dust is one of the five large disasters in colliery, mine dust control is also that the important component part of colliery " one through three prevention " technical system is in underground work process, wet dust collection technology is that mine down-hole applies the most general a kind of mode, wet dust removal room adopts tunneling boring water curtain dust-proof, namely one row's nozzle is set at top, tunnel, nozzle is connected with inlet pipeline and is controlled by valve switch, because valve switch is arranged on the side of dustproof water screen, double-direction control can not be carried out, when pedestrian is by drenching clothes during water curtain, can affect greatly workman's operation and safety in production, and open not in time after closedown water curtain, spray time can be caused inadequate, dust-proof effect is bad.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can the spray dust remover of double-direction control, this device adopts double-direction control, prevents staff by being drenched during dust arrester.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: colliery under-well bi-directional linkage sprayer, comprise water inlet pipe, outlet pipe, preposition threeway, rearmounted threeway, preposition two-way linkage by-pass valve control, rearmounted two-way linkage by-pass valve control, up-hill line, downstream pip and drencher head, described preposition threeway is connected with water inlet pipe, up-hill line and downstream pip respectively, and rearmounted threeway is connected with outlet pipe, up-hill line and downstream pip respectively; Described drencher head is connected with outlet pipe, and drencher head is arranged between preposition threeway and rearmounted threeway; Described preposition two-way linkage by-pass valve control is arranged on the side near preposition threeway and is connected with up-hill line and downstream pip respectively, and rearmounted two-way linkage by-pass valve control is arranged on the side near rearmounted threeway and is connected with up-hill line and downstream pip respectively.
Preferably, described preposition two-way linkage by-pass valve control and rearmounted two-way linkage by-pass valve control are made up of the upper end Water stop valve and lower end Water stop valve being connected to axle two ends, the reverse placement of lower end Water stop valve opposite upper Water stop valve.
The colliery using method of under-well bi-directional linkage sprayer, during use, preposition two-way linkage valve and rearmounted two-way linkage valve are pushed simultaneously to top, up-hill line is connected, water under high pressure flows to drencher head by water inlet pipe through preposition threeway, up-hill line, rearmounted threeway, outlet pipe, is sprayed form water curtain by drencher head;
When personnel need to go to rear side on front side of water curtain, promoted preposition two-way linkage valve side, such rising main and descending water pipe end simultaneously, and personnel pass through water curtain;
After personnel pass through, promoted by rearmounted two-way linkage by-pass valve control to opposite side, descending water pipe is connected, water under high pressure flows to drencher head through preposition threeway, descending water pipe, rearmounted threeway, outlet pipe successively, is sprayed form water curtain by drencher head; When personnel need to go to front side on rear side of water curtain, operation is carried out in the manner described above.
Adopt technical scheme of the present invention, following beneficial effect can be obtained:
Two-way linkage atomization mechanism structure of the present invention is simple, safe and reliable, is easy to operation, can ensures that worker is not drenched clothes by water curtain, ensure that time and the dust-proof effect of spraying.This device overcomes dustproof water screen in the past can not the defect of double-direction control, to use after this device personnel by can free switch before and after water curtain, be conducive to the dust-proof management of mine, it also avoid the situation of pedestrian by clothes being drenched during water curtain, ensure that time and the dust-proof effect of spraying.
