Description
Technical field
The utility model relates to a kind of underground mine use dustproof facilities, relates in particular to the airborne foam dust-removing device of fully-mechanized digging machine.
Background technology
A large amount of coal dust that can produce in colliery digging manufacturing process, be full of whole operation field, when particularly fully-mechanized digging machine is constructed, the Dust Capacity of its output is maximum, and a large amount of coal dusts can make operation place visibility reduce, and affects job safety, because the driver of fully-mechanized digging machine is nearest from producing dirt pits, coal dust not only affects their operation, also can suck a large amount of coal dusts, and have a strong impact on the healthy of driver.
At present, for a large amount of coal dusts, generally adopt water pipe to carry out sprinkle water and spray dedusting or utilize air duct purifying and dedusting, though wherein sprinkle water and spray dedusting is simple, water consumption is large and to the depositing dust efficiency of respirable dust lower (approximately 30%～50%), and in use procedure, shower nozzle easily stops up; And the too little impact of the spraying dirt effect of going out, the too large fully-mechanized digging machine sight line that affects of spraying.And there is the limited problem of air quantity of processing in air duct purifying and dedusting, the dust at driver of roadheader place is removed to weak effect, have a strong impact on driver's health; And due to the mass ratio of dedusting fan large (being generally 2t left and right), mobile difficulty forward, especially runs into tunnel fluctuation ratio when larger.
Utility model content
The utility model is exactly in order to overcome the above problems, and a kind of good dedusting effect is provided and is convenient to the mobile airborne foam dust-removing device of fully-mechanized digging machine.
In order to achieve the above object, the utility model provides fully-mechanized digging machine airborne foam dust-removing device, comprise and be located at the blower fan in air intake lane and the water pump being connected with high-pressure water pipe, the water side of described water pump is connected with the foam maker being fixedly arranged on fully-mechanized digging machine by water pipe, and the top of described foam maker is provided with blowing agent case; In the middle of described water pipe, be provided with three way cock, two arrival ends of described three way cock respectively with the water side of water pump, the port of export of blowing agent case is connected, its port of export is connected with the arrival end of foam maker; The outlet air end of described blower fan is connected with foam maker by airduct; The liquid outlet of described foam maker is connected with at least three shower nozzles by foam dispenser, and described three shower nozzles lay respectively at top, the left and right-hand of fully-mechanized digging machine head.
Further, the port of export of described blowing agent case is provided with valve and batchmeter successively.
Further, described water pipe is provided with water solenoid valve, and airduct is provided with wind-powered electricity generation magnet valve, described water solenoid valve connect with wind-powered electricity generation magnet valve after be located at fully-mechanized digging machine driver's cabin in press button be electrically connected to.
Further, the pipeline between described water pipe, airduct and connection foam maker liquid outlet and shower nozzle is the high-pressure rubber pipe that diameter is 15-20mm.
Dust arrester of the present utility model is that to utilize the existing water under high pressure in down-hole and compressed airflow be power, by add blowing agent in water pipe, form uniform expanding foam solution and enter in foam maker, in foam maker, lead to compress wind simultaneously, expanding foam solution is foamed in foam maker, produce high-performance foam, then by foam dispenser, be assigned to equably and be located at fully-mechanized digging machine head upper, left and right-hand shower nozzle, surrounding at fully-mechanized digging machine sprays, its foam can cover fully-mechanized digging machine surrounding space, dirt source is wrapped up and being landed, thereby reach the object of dedusting, emphasis is to have protected driver of roadheader to avoid coal dust to absorb, protected their health.And dust is attached on coal petrography wall, thereby reach the effect of pre-wetting rib.
This device improves the depositing dust efficiency of mechanized extraction work plane greatly, and its depositing dust efficiency has reached 70%, is 2.5 times of water mist dust fall efficiency.And this device also can be combined use with water mist dust-removing equipment, more can improve efficiency of dust collection.Meanwhile, because the particle diameter of foam is large, parcel dust is many, when improving efficiency of dust collection, has also saved water.
In addition, because the equipment such as foam maker, blowing agent case are all located on fully-mechanized digging machine, use into connecting again water pipe and airduct, thereby having saved manpower carries, enhance productivity.
