Description
Technical field
The invention belongs to mineral engineering field, and in particular to segmented coal bunker dust falling system.
Background technology
Currently, the coal newly adopted usually is pre-stored in shaft coal pocket by underground coal mining, ground is transported to when reaching a certain amount of, so
And in the coal bunker of relative closure, since toppling over for coal can produce substantial amounts of dust, up to 50000mg/m sometimes3, such as electricity
Spark or underground electrical leakage, it is likely that explosion occurs and destroys coal bunker, consequence is hardly imaginable, explosion-suppressing method currently on the market
Mainly for the processing after explosion, such hysteresis quality brings very big security risk to underground site operation.
The content of the invention
The purpose of the present invention is：There is provided segmented coal bunker dust falling system, to overcome it is above-mentioned in the prior art the defects of.
The adopted technical solution is that：
Segmented coal bunker dust falling system, it is characterized in that：Including multiple dust density detectors, more main jet water drenchings
Pipe and controller, the multiple dust density detector are arranged at coal bunker inner wall and vertically even portion, the more main jets
Spray pipe is vertically arranged in coal bunker, and multiple high-pressure water nozzles are set on every main jet spray pipe, and the multiple dust concentration is visited
Survey device and multiple high-pressure water nozzles are connected with controller respectively.
Further, the auxiliary spray header for being arranged at coal bunker internal upper part is further included, is set on the auxiliary spray header
Multiple spray apertures.
Further, the auxiliary spray header is in spiral of Archimedes type.
Further, a plurality of straight slot is radially set on the auxiliary spray header, the spray apertures are arranged in straight slot.
Further, multiple flushing bend pipes certainly that Open Side Down are set on the main jet spray pipe, are set from rinsing on bend pipe
Radio magnet valve is put, the radio magnet valve is connected with controller.
Further, the radially even portion of more main jet spray pipes is in same circumference.
Further, the high-pressure water nozzle uses injection type secondary atomized spray head.
The beneficial effects of the invention are as follows：When coal pours into coal bunker, the dust concentration difference of different height is very big in coal bunker,
In the technical program, multiple dust detectors monitor the dust concentration of different height in coal bunkers in real time, trigger the height of corresponding height
Sprinkler head is pressed to form water mist, water utilization rate is high, energy conservation and environmental protection, meanwhile, auxiliary spray header further ensures that spraying effect.
From rinse bend pipe can periodic flushing main jet spray pipe, prevent from blocking.

Embodiment
Below in conjunction with the attached drawing of the present invention, technical scheme is clearly and completely described.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, belongs to the scope of protection of the invention.
As Figure 1-Figure 4, the present embodiment provides a kind of segmented coal bunker dust falling system, including 3 dust concentration detections
Device 1,4 main jet spray pipe 2 and controller, 3 dust density detectors 1 are arranged at 3 inner wall of coal bunker and vertically even portion,
4 main jet spray pipes 2 are vertically arranged in coal bunker 3, and radially even portion is in same circumference.3 are set on every main jet spray pipe 2
A high-pressure water nozzle 4, respectively with 31 same height placements of dust density detector, 3 dust density detectors 1 and 12 high pressures
Sprinkler head 4 is connected with controller respectively.
The auxiliary spray header 5 for being arranged at 3 internal upper part of coal bunker is further included, aids in setting multiple spray apertures on spray header 5
6.It is in spiral of Archimedes type to aid in spray header 5.A plurality of straight slot 7 is radially set on auxiliary spray header 5, spray apertures 6 are set
Put in straight slot 7.Multiple flushing bend pipes 8 certainly that Open Side Down are set on main jet spray pipe 2, are set wirelessly from rinsing on bend pipe 8
Solenoid valve 9, radio magnet valve 9 are connected with controller.High-pressure water nozzle 4 uses injection type secondary atomized spray head.
During work, each dust density detector is formed by controller and level 4 high-pressure water nozzles to be fed back, institute
When the dust concentration of detection is higher than predetermined threshold, start corresponding high-pressure water nozzle, otherwise close, meanwhile, aid in spray header
State is maintained a normally open, controller is periodically opened from the radio magnet valve rinsed on bend pipe and rinses main jet spray pipe.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
