Description
Technical field
The present invention relates to mining technical field, particularly relate to a kind of injection apparatus for depositing dust.
Background technology
In shaft production operation, coal-winning machine or development machine can produce a large amount of dust when cutting coal body (or rock mass), and dust concentration is up to 3000 ~ 5000mg/m
3the dust of high concentration, not only affect mine normal production, also be the major hidden danger causing mine dust to explode, more directly endanger the healthy of mine operation personnel, therefore, have employed multiple dedusting and measurements for reduction both at home and abroad at present, prevent and treat the dust of getting working face high concentration, its major measure has:
(1), external spraying in mining machinery: because nozzle is directly installed on cutting head, the easy plug nozzle when cutting coal body, makes its measure of spraying perform practically no function, inoperative.
(2), spray dust-reducing system is followed the tracks of in dirt source: the feature of native system is, by being arranged on transmitter on coal-winning machine or development machine and receiver, when coal-winning machine advances near a pack support, the signal sent by transmitter, make the nozzle spray that this pack support is installed, reach the object producing a large amount of dust when reducing cutting.This system Problems existing is: transmitting or receiver are often because dust blocks, and make its performance very reliable, Operation system setting is complicated in addition, Main Control Tank, electromagnetic valve, water route sebific duct, nozzle spread all over work plane, affect work, because its facility is numerous and diverse, equipment and instrument, pipeline are many, thus cost is also high, set of system can up to 50 ~ 1,000,000 yuan, and in addition, system is very unreliable yet, working service is numerous and diverse, and thus native system does not obtain a large amount of popularizations.
(3), High Pressure Spray for Dust Suppression device: native system is the high-pressure pump of employing >=8MPa, its water under high pressure produced is by pressure duct and be arranged on water smoke that the secondary negative-pressure dust removal machine on coal-winning machine ejects and reduce the dust that coal-winning machine produces, the shortcoming of this system is: high-pressure rubber pipe is expensive, and the Distance geometry spray area that negative-pressure dust removal machine sprays is limited, dust-laying effect is also not bery desirable, in addition high pressure line maintenance workload is large, uses trouble, thus uses and also do not obtain large-scale popularization.
(4), dirt cleaning system taken out by development machine deduster: native system adopts the devices such as dust shield, dust collection pipeline, deduster, and the high concentrate dust produced when being cut by development machine sucks in deduster and concentrates purification, reaches the object reducing work plane dust.Native system is respond well, but moving at random of deduster dust collection pipeline is established, and the diffusion of the unordered dust of shutoff driving face, and a set of dust control device must be adopted, all these, driving face is made to be that a series of equipment that dedusting adopts are numerous, management, safeguard, use very complicated, although thus its result of use is better, because all devices cost is also higher, generally can reach about 200,000 yuan, also not obtain a large amount of promoting the use of.
For the cleaner on mining machinery and dust falling system, there is above drawback and problem, the present invention proposes the machine-carried type spraying machine for mining machinery depositing dust, economy, management maintenance easily dust falling device simple and practical by one, reach the object of purification and dedusting on the spot.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of injection apparatus for depositing dust, for the problem solving existing dedusting and device for reducing dust is economical and practical not and maintenance is complicated.
For achieving the above object and other relevant objects, the invention provides following technical scheme:
A kind of injection apparatus for depositing dust, comprise circular duct, motor, circular reducing airduct and injection equipment, one end that circular reducing dust diameter is larger is connected on one end of circular duct, one end that circular reducing dust diameter is less connects injection equipment, motor is two-axis synchronous machine, and the two ends rotating shaft of two-axis synchronous machine is connected to impeller.
Preferably, along vane edge rotate on the circular duct inwall at place, path, be respectively arranged with copper ring.
Preferably, the other end of circular duct is connected with a blast pipe.
Preferably, injection equipment comprises water inlet pipe, injection spray pipe and nozzle, and water inlet pipe is connected to injection spray pipe for accessing water head site, and injection spray pipe is provided with multiple nozzle be communicated with injection spray pipe.
As mentioned above, the present invention at least has following beneficial effect: by being arranged on coal-winning machine fuselage by machine-carried type depositing dust injection apparatus, move with coal-winning machine and move forward, when coal-winning machine starts, spraying machine also starts simultaneously, high speed water mist directive cutting head, a umbrella shape water smoke cover is formed in cutting head region, the dust that cutting head is produced can not to external diffusion, and high speed water mist and dust collide moistening, cohesion, reach the object of dedusting on the spot, jack on spraying machine can rely on hydraulic pressure or oil pressure cntrol up and down or left and right change injection direction, reach the object of effective depositing dust.
