Abstract
The utility model discloses an automatic water curtain dust removal device of tunnelling working face, concretely relates to dust collector technical field. It has been solved current coal mine tunnel and has removed dust through artifical watering, and there have dust removal effect to be poor, causes the not enough of the serious ponding in tunnel. This automatic water curtain dust removal device of tunnelling working face including the raceway, evenly is provided with water jet equipment, dust concentration monitoring devices and alarm on the raceway, water jet equipment includes multi -orifice sprinkler head, and water jet equipment is more than four, and each water jet equipment is towards diverse. Dust concentration monitoring devices is explosion -proof dust concentration monitoring devices, and the alarm is explosion -proof alarm. One side of raceway is equipped with the automatic valve, and water jet equipment is linked together with the raceway, and dust concentration monitoring devices all sets up under the raceway with the alarm, and dust concentration monitoring devices is connected with the automatic valve is automatically controlled, fixedly connected with couple directly over the raceway. The couple is linked up with to more than three for automatic hasp couple.
Description
Technical field
This utility model relates to dust arrester technical field, is specifically related to a kind of roadway head automatic water curtain dust arrester。
Background technology
In coal mine roadway tunneling process, it usually needs bursting work, but a large amount of dust, not only air pollution after explosion, can be produced, the health of site operation personnel is harmful to, and has great potential safety hazard, as coal dust flies upward, meet naked light and cause explosion accident。Current dust prevention is manually sprinkled water after simply wearing mask and explosion dedusting, but acts on only small。Substantial amounts of watering dedusting both waste water resources also result in the serious hydrops in tunnel, cause that work on the spot environment is extremely severe。
Utility model content
The purpose of this utility model is by dedusting of manually sprinkling water for existing coal mine roadway, there is dust removing effects difference, cause the deficiency of the serious hydrops in tunnel, propose by arranging water-supply-pipe and water injector, control water injector water spray by automatic valve, form omnibearing water curtain and carry out a kind of roadway head automatic water curtain dust arrester of dedusting。
This utility model specifically adopts the following technical scheme that
A kind of roadway head automatic water curtain dust arrester, including water-supply-pipe, described water-supply-pipe is evenly arranged with water injector, dust concentration monitoring device and alarm, the side of described water-supply-pipe is provided with automatic valve, described water injector is connected with water-supply-pipe, described dust concentration monitoring device and alarm may be contained within the underface of water-supply-pipe, and described dust concentration monitoring device electricly connects with automatic valve, and the surface of described water-supply-pipe is fixedly connected with hook。
Preferably, described water injector includes porous nozzle, and described water injector is more than four。
Preferably, described hook is automatic locking hook, and described hook is more than three。
Preferably, described dust concentration monitoring device is explosion-proof dust concentration monitoring device, and described alarm is explosion-proof alarm。
This utility model has the beneficial effect that this roadway head automatic water curtain dust arrester, and structural design is simple and conveniently uses, and the advantage especially with automaticity dedusting reduces artificial watering dust-removing process and avoids site operation personnel's respiratory infections；Dust concentration monitoring device can carry out real time on-line monitoring at work surface, and can pass through this device and control penstock and open and pass water through water-supply-pipe, not only using water wisely and also work surface hydrops is few；Dust concentration can be exceeded standard warning by alarm device, notifies that workman withdraws work surface, and makes skilled addressee adopt an effective measure process, it is ensured that the safety of tunnel work surface workmen；The dust removing effects of tunnel work surface is effectively raised towards many groups water injector of lane space all directions。
Accompanying drawing explanation
Fig. 1 is that this roadway head automatic water curtain dust arrester assembles structural representation in tunnel；
Fig. 2 is this roadway head automatic water curtain dust arrester structural representation；
Fig. 3 is automatic locking hook structure schematic diagram。
Wherein, 1 is tunnel, and 2 is water-supply-pipe, and 3 is water injector, and 4 monitor device for dust concentration, and 5 is alarm, and 6 is automatic valve, and 7 is hook, and 8 is crossbeam。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described further:
As Figure 1-3, a kind of roadway head automatic water curtain dust arrester, including water-supply-pipe 2, water-supply-pipe 2 is evenly arranged with water injector 3, dust concentration monitoring device 4 and alarm 5, water injector 3 includes porous nozzle, water injector 3 is more than four, and each water injector 3 is towards different。Dust concentration monitoring device 4 is explosion-proof dust concentration monitoring device, and alarm 5 is explosion-proof alarm。The side of water-supply-pipe 2 is provided with automatic valve 6, water injector 3 is connected with water-supply-pipe 2, dust concentration monitoring device 4 and alarm 5 may be contained within the underface of water-supply-pipe 2, and dust concentration monitoring device 4 electricly connects with automatic valve 6, and the surface of water-supply-pipe 2 is fixedly connected with hook 7。Hook 7 is linked up with for automatic locking, and hook 7 is more than three。
The specific works principle of this roadway head automatic water curtain dust arrester is: by the crossbeam 8 that automatic locking hook secures the device in tunnel 1, when tunnel 1 dust concentration exceedes code safe level, dust concentration monitoring device 4 controls automatic valve 6 and opens, make current pass through water-supply-pipe 2 to spray through porous nozzle, in tunnel 1, form omnibearing water curtain, carry out automatic dust removing work。
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model。
