Description
Technical field
The present invention relates to a kind of road heading machinery fixture, particularly relate to a kind of dust arrester for road heading machinery.
Background technology
At present, the road heading machinery of domestic production is generally without cleaner.Although the independent deduster of domestic indivedual manufacturer production, the reason such as larger because the deduster inlet scoop is too far away apart from work plane, cleaning coal slime difficulty, institute take up space, the ratio that is actually 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 greatly in various degree pneumoconiosis, 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.
Dust removing device for tunneling machine of the present invention is by bracing or strutting arrangement, is arranged on Telescopic air duct, rigidity air duct on bracing or strutting arrangement, and be arranged on that closed channel on the road heading machinery drag conveyor forms, described bracing or strutting arrangement is made of skid, column and air duct supporting plate, the air duct supporting plate is fixed on the top of skid by column, front end at skid is equipped with two multi-stage expansion pull bars, and the other end of multi-stage expansion pull bar is connected on the back axle of road heading machinery; Described 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; Described closed channel is comprised of the sidewall that is arranged on drag conveyor chute both sides and the cover plate that covers on sidewall, be provided with the wind of a level-coal dividing plate in the closed channel rear end, closed channel is separated into the coal flowing 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, for water spray dust in passage.
During dust arrester work, the coal dust that road heading machinery cutting coal body produces all enters closed channel under the suction function of induced draft fan, after the water smoke of the water spout ejection that is arranged on the way is fully moistening, a part falls under gravity into channel bottom, transport on leather belt reshipment machine with coal stream and transport, a part flows to the wind into Telescopic air duct and rigidity air duct, discharges through induced draft fan, thereby has reached the purpose of dedusting.
In order to guarantee the seal in closed channel, the present invention also is equipped with air leakage preventing device in coal flowing channel, and described air leakage preventing device is comprised of the multi-layer movable flap, is arranged on 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 be at door curtain made of cloth surface sprinkling water smoke, reach and not only realize the purpose of transporting coal but also realizing Anti-air-leakage.
For the coal cinder that prevents larger volume can't pass through coal flowing channel, the present invention can also be arranged to wind-coal dividing plate the mode that can move up and down, when having the bulk bastard coal to pass through, wind-coal dividing plate rises the bulk bastard coal is passed through smoothly, and wind-coal dividing plate falls and sets back subsequently.
The present invention is connected with noise damper in the rear end of induced draft fan, the noise that produces to reduce induced draft fan work.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 dust arrester deposits to when to a certain degree needing to clear up, Telescopic air duct can be pulled down vertically and be hung, 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, during coal slime in cleaning rigidity air duct, the drawer of drawer type funnel bottom is pulled out, and uses the high pressure water flushing wash clean, then its playback is got final product.
After dust removing device for tunneling machine of the present invention can be connected by linkage with existing road heading machinery, form the passage of exhausting and fortune coal.Air draft passage length is long, a large amount of coal slimes only has a small amount of coal slime to enter in Telescopic air duct and rigidity air duct with the outward transport of coal stream, and coal mud clearing work greatly alleviates, overcome existing deduster coal mud clearing difficulty large, coal slime is difficult for outward transport and coal slime and the problem such as piles up in the tunnel.
Dust removing device for tunneling machine of the present invention can easily with the road heading machinery reach, overcome the drawback that existing deduster moves difficulty by two multi-stage expansion pull bars and Telescopic air duct.
Description of drawings
Fig. 1 is the structural representation of dust removing device for tunneling machine of the present invention.
The specific embodiment
The structure of dust removing device for tunneling machine as shown in Figure 1, by the drag conveyor 19 of installing on road heading machinery, bracing or strutting arrangement, be arranged on Telescopic air duct 7, rigidity air duct 8 on bracing or strutting arrangement, and be arranged on several parts of closed channel on road heading machinery drag conveyor 19 and consist of.
