Description
Technical field
It the utility model is related to the dust arrester that a kind of underground coal mine driving face uses.
Background technology
At present, still drilled using open, dry process in underground coal mine driving face, usually bored with EH260
Machine perforating, no dustproof dust-collecting equipment, coal dust is very big on working face, and working environment is poor, the health of badly damaged worker, for a long time at this
Kind environmental work can cause anthraco-silicosis, and the Dust Concentration of working face is high, it is also possible to cause gas and dust explosion, have very big
Potential safety hazard.
The content of the invention
The purpose of the utility model is to overcome the shortcomings of above-mentioned prior art, there is provided it is dense that one kind can reduce working face in the pit coal dust
Spend, prevent the wet type jet dust arrester of gas and dust explosion.
The utility model includes coal powder collection cylinder, water pump, pond and screen pack, high-pressure rubber pipe and jet pump, drilling rod and brill
Rod guiding device；Jet pump includes suction inlet, mixing chamber, anemostat and nozzle；Coal powder collection cylinder is the open cylinder in front end, is bored
Bar passes through coal powder collection tube rear end center, and coal powder collection cylinder is fixed on drill rod-guiding device front end, drilling rod dress by screw
In rig drive device, drill rod-guiding device is by drill-rod clamping；The nozzle water inlet of jet pump passes through high-pressure rubber pipe and water pump
Delivery port is connected, and high-pressure rubber pipe both ends are tightened with clip；Jet pump diffuser is tightened with drainpipe with clip, the drainpipe other end
Access in pond；Water pump is mounted in pond；Jet Pump Suction Nozzle is welding on coal powder collection cylinder by melt process.Among pond
Set one piece of screen pack that pond is separated into two regions, water pump, the access of another region and jet pump are placed in a region
The drainpipe outlet of anemostat connection.
In use, push platform water pump button, starts water pump in pond, water flows through the entrance of jet Unit injector water inlet,
Flowed out through Jet Pump Mixture room from anemostat, negative pressure is formed in coal powder collection cylinder；Start rig to drill；Drill formed coal
Dirt is inhaled into jet Pump Suction Nozzle, is flowed into through jet pump diffuser in pond.Into the coal dust in pond after precipitating, filtering
It can recycle.
The utility model can substantially reduce the Dust Concentration of working face in the pit, be effectively improved the working environment of underground labour,
It can effectively prevent and reduce the anthraco-silicosis for endangering operating personnel's health.Tunnel floating Dust Concentration is reduced, suppressing coal dust can
To prevent gas and dust explosion, drill operating efficiency and security are improved.
