Abstract
The utility model relates to a gold mine downhole automatic spray dustfall system. A spray head comprises a sprayer core body (5) and a sprayer cover (6) installed at the front end of the sprayer core body (5), wherein a cylindrical mist area (7) taken as a mist space is reserved between the front end surface of the sprayer core body (5) and the sprayer cover (6), the sprayer core body (5) is provided with a core body water hole (5-1), the rear end of the core body water hole (5-1) is communicated with the front end of a main water pipe (1), the front end of the core body water hole (5-1) is communicated with the mist area (7), the sprayer cover (6) is provided with spray holes (6-1), and the front end of the mist area (7) is communicated with the spray holes (6-1). Dust generated after blasting operation can be effectively intercepted by the gold mine downhole automatic spray dustfall system, so that the downhole working environment is guaranteed to be clean, and the dust concentration is lowered.
Description
Technical field
The utility model relates to a kind of gold mine down-hole auto spraying dust falling system.
Background technology
Gold mine down-hole dust mainly results from links such as roadway digging, supporting, transportation, loading and unloading, lifting, and its borehole blasting dust-producing amount accounts for about 40% of manufacturing process dust-producing amount.According to measuring and calculating, big gun is adopted the dust concentration of the scope of operation after blowing out under the situation of no any dust prevention and is reached 300～500mg/m
3About, explosion moment generation dust quantity is up to thousands of extremely tens thousand of mg/m
3
Existing gold mine down-hole dust processing mode mainly is the ventilation dust discharge, and after opening blower fan, the dust of high concentration will be diffused into other spaces rapidly, enlarges contaminated area and causes secondary pollution.
The utility model content
The utility model technical problem to be solved is, a kind of gold mine down-hole auto spraying dust falling system is provided, and the dust that produces after the bursting work is effectively tackled, and guarantees the cleaning of working environment at coal mines, reduces dust concentration.
For solving above technical problem, the utility model has adopted following technical scheme:
A kind of gold mine down-hole auto spraying dust falling system; Comprise total valve, electromagnetic valve, strainer and the fog-spray nozzle of connecting successively through water main; It is characterized in that: said fog-spray nozzle comprises the shower nozzle core body and is installed in the nozzle cap of shower nozzle core body front end, and leaves between shower nozzle core body front end face and the nozzle cap as the columned fog-zone of making of making the mist space; Wherein the shower nozzle core body has the core body water hole, and the rear end in core body water hole is communicated with the front end of water main, the front end in core body water hole with make the fog-zone and be communicated with; Said nozzle cap has spray holes, and the said front end of making the fog-zone is communicated with described spray holes.
Also comprise the bypass water pipe that has hand by-pass valve, the water inlet end of this bypass water pipe is connected on the water main between total valve and the electromagnetic valve, and the water side is connected on the water main between strainer and the fog-spray nozzle.
The good effect of the utility model is:
The first, under the water pump effect, the current that get into water main filter the back through strainer and get into the sprinkler core body, and spray into through the core body water hole and to make in the fog-zone, High-Pressure Water and the inwall high speed impact formation water smoke of making the fog-zone, and water smoke sprays through spray holes.It is nozzle specially used that to make fog effect better.Find through on-the-spot the use, use the utility model, can effectively tackle the dust that produces after the bursting work preferably, guarantee the cleaning of working environment at coal mines, reduce dust concentration, protection operating personnel's physical and mental health.
Than single ventilation depositing dust mode, behind the use ventilation atomizing de-dusting, airborne dust content has reduced by 60.73%, has reduced the contaminated area of dust, has realized the improvement to the dust source.
In addition, use the utility model can also reduce the work plane temperature, form convection current, reduce toxic and harmfuls such as blasting fume and nitrogen oxide, reach through do not choke people's purpose of the gas of spray.
The second, the utility model is provided with the bypass water pipe as emergent water route, under the situation of electromagnetic valve damage or plugged filter, can continue to accomplish the atomizing de-dusting operation.
Description of drawings
Fig. 1 is the structure and the workflow sketch map of the utility model.
The specific embodiment
Below in conjunction with instance the utility model is further specified.
Like Fig. 1, the utility model comprises total valve 2, electromagnetic valve 3, strainer 4 and the fog-spray nozzle of connecting successively through water main 1.Said fog-spray nozzle comprises shower nozzle core body 5 and is installed in the nozzle cap 6 of shower nozzle core body 5 front ends, and leaves between shower nozzle core body 5 front end faces and the nozzle cap 6 as the columned fog-zone 7 of making of making the mist space.Wherein shower nozzle core body 5 has core body water hole 5-1, and the rear end of core body water hole 5-1 is communicated with the front end of water main 1, the front end of core body water hole 5-1 with make fog-zone 7 and be communicated with.Said nozzle cap 6 has spray holes 6-1, and the said front end of making fog-zone 7 is communicated with described spray holes 6-1.
Under the water pump effect, the current that get into water main 1 filter the back through strainer 4 and get into sprinkler core body 5, and 5-1 sprays into and makes in the fog-zone 7 through the core body water hole, High-Pressure Water and the inwall high speed impact formation water smoke of making fog-zone 7, and water smoke sprays through spray holes 6-1.
The utility model can also comprise the bypass water pipe 8 that has hand by-pass valve 9.The water inlet end of this bypass water pipe 8 is connected on the water main 1 between total valve 2 and the electromagnetic valve 3, and the water side is connected on the water main 1 between strainer 4 and the fog-spray nozzle.Under the situation that electromagnetic valve 3 damages or strainer 4 stops up, said bypass water pipe 8 can be used as emergent water route and uses.
