Description
Technical field
The present invention relates to a kind of road heading machinery and use fixture, particularly relate to a kind of dust arrester that is used for road heading machinery.
Technical background
At present, the road heading machinery of domestic production does not generally have cleaner.Though the independent deduster of domestic indivedual manufacturer production, the reason such as bigger owing to the deduster inlet scoop is too far away apart from work plane, cleaning coal slime difficulty, institute take up space, the actual ratio that is used in driving face is not high.So that be engaged in the getting working face of work more than 20 years and connect the dirt coal miner and suffer from pneumoconiosis in various degree greatly, particularly use the work plane operating personnel of road heading machinery.
Summary of the invention
To the objective of the invention is in order addressing the above problem, to provide a kind of and the whole supporting dust arrester of road heading machinery.
Road heading machinery of the present invention is by bracing or strutting arrangement, is installed in Telescopic air duct, rigidity air duct on the bracing or strutting arrangement with dust arrester; And be installed in that closed channel on the road heading machinery drag conveyor forms; Said bracing or strutting arrangement is made up of skid, column and air duct supporting plate; The air duct supporting plate is fixed on the top of skid through column, at the front end of skid two multi-stage expansion pull bars is installed, and the other end of multi-stage expansion pull bar is connected on the back axle of road heading machinery; Said rigidity air duct is fixedly mounted on the air duct supporting plate, and its front end is connected with Telescopic air duct on being placed on the air duct supporting plate, and back outlet connects induced draft fan; Said closed channel is formed with the cover plate that covers on sidewall by being installed in drag conveyor chute side walls; Be provided with the wind-coal dividing plate of a level in the closed channel rear end; Closed channel is separated into the fortune coal channel of below and the air draft passage of top, and the outlet of air draft passage connects Telescopic air duct.
Wherein, on the inwall of closed channel and rigidity air duct, a plurality of water spouts are installed, are used for water spray dust in passage.
During dust arrester work; The coal dust that road heading machinery cutting coal body produces all gets into closed channel under the suction function of induced draft fan, after the water smoke of the water spout ejection that is provided with on the way was fully moistening, a part fell under gravity into channel bottom; Transport on the leather belt reshipment machine with coal stream and to transport; A part flows into Telescopic air duct and rigidity air duct with the wind, discharges through induced draft fan, thereby has reached the purpose of dedusting.
In order to guarantee the seal in the closed channel, the present invention also is equipped with air leakage preventing device in the fortune coal channel, and said air leakage preventing device is made up of multilayer moveable hinge carrier bar, is installed in the below of wind-coal dividing plate, and the lower end contacts with drag conveyor.One deck antistatic fold door curtain made of cloth also is installed in the outside of every layer of moveable hinge carrier bar, and this door curtain made of cloth can the double buckle structure connect, and is easy to change.Simultaneously, can also reach and not only realize transporting coal but also realize anti-purpose of leaking out at door curtain made of cloth surface sprinkling water smoke.
For the coal cinder that prevents larger volume can't be through the fortune coal channel; The present invention can also be arranged to the mode that can move up and down with wind-coal dividing plate; When the bulk bastard coal passed through, wind-coal dividing plate rose the bulk bastard coal is passed through smoothly, falls and sets back with after wind-coal dividing plate.
The present invention is connected with noise damper in the rear end of induced draft fan, to reduce the noise that induced draft fan work produces.In the exit of noise damper the gas alarming cutoff instrument is installed, when the gas alarming cutoff instrument detects gas in distinguished and admirable and reaches warning concentration, implements the outage of reporting to the police.
When the coal slime in the dust arrester deposits to a certain degree need clear up the time, can Telescopic air duct be pulled down vertically and hang, clear up the coal slime on its inwall.Rigidity air duct dismounting difficulty can be equipped with the drawer type funnel on the rigidity air duct, when clearing up the coal slime in the rigidity air duct, the drawer of drawer type funnel bottom is pulled out, and is clean with high pressure water washing, its playback got final product again.
Road heading machinery of the present invention can form the passage of exhausting and fortune coal with after existing road heading machinery is connected through linkage with dust arrester.Air draft passage length is long; A large amount of coal slimes only has a small amount of coal slime to get in Telescopic air duct and the rigidity air duct with the outward transport of coal stream, and coal mud clearing work greatly alleviates; It is big to have overcome existing deduster coal mud clearing difficulty, and coal slime is difficult for outward transport and coal slime and problem such as in the tunnel, piles up.
Road heading machinery of the present invention can overcome the drawback that existing deduster moves difficulty with dust arrester easily with the road heading machinery reach through two multi-stage expansion pull bars and Telescopic air duct.
Description of drawings
Fig. 1 is the structural representation of road heading machinery of the present invention with dust arrester.
The specific embodiment
Road heading machinery is as shown in Figure 1 with the structure of dust arrester; By the drag conveyor of installing on the road heading machinery 19, bracing or strutting arrangement, be installed in Telescopic air duct 7, rigidity air duct 8 on the bracing or strutting arrangement, and be installed in several parts of closed channel on the road heading machinery drag conveyor 19 and constitute.
Described closed channel is installed on the road heading machinery drag conveyor 19, by being installed in drag conveyor 19 chute side walls 3, covering fortune coal, air draft passage that cover plate 2 on sidewall 3 seals around forming with the drag conveyor chute.Be provided with the wind-coal dividing plate 4 of a level in the closed channel rear end, closed channel is separated into the fortune coal channel of below and the air draft passage of top, wind-coal dividing plate 4 is arranged to manner, can move up and down, and the coal cinder of being convenient to larger volume passes through.The outlet 6 of air draft passage connects Telescopic air duct 7.
On the sidewall of closed channel 3 and cover plate 2, have rule or irregular a plurality of aperture, water spout 1 is installed in the aperture.In the fortune coal channel, air leakage preventing device 5 is installed, air leakage preventing device 5 is made up of the multilayer moveable hinge carrier bar that is installed in wind-coal dividing plate 4 belows, and the lower end contacts with drag conveyor 19.One deck is installed in the outside of every layer of moveable hinge carrier bar has the easily changeable antistatic fold of the double buckle door curtain made of cloth.
