Description
Technical field
The utility model belongs to coal mine gas drainage tailrace technical field, relates generally to a kind of without drift timing automatic draining
Device.
Background technique
Gas drainage is one of link mostly important in coal production, with the extraction of gas, water contained in coal seam
Also it can be pumped in gas pipe, in order to which the water excluded in gas pipeline just needs to use tailrace.Currently, tailrace on the market
There are many kinds of, such as negative pressure tailrace, positive-pressure water draining device.There are many problems for some tailraces that coal mine uses, as structure is multiple
Miscellaneous, the multiple materials such as built-in buoy, spring, magnet are discharged water by complicated mechanical structure using positive pressure or negative pressure；Discharge water effect
Fruit is poor, mechanical structure using will appear for a period of time get rusty, card resistance phenomena such as, can not discharge water；Special messenger is needed to operate, some discharge water
Device needs artificial mechanism to operate in the process of water release, increases labour cost；The process of discharging water can generate gas leakage, some tailraces
It needs to open jettison gear in the process of water release, will appear gas leakage during discharging water, there are certain security risks；It repairs into
This is higher, and complicated tailrace part is more, and the part for the replacement that needs repairing is more, and maintenance cost is caused to increase.
Utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provide that a kind of structure is simple, can be improved and discharges water
Safety, the hollow cylinder timing automatic water drainage device for reducing labor intensity, reducing maintenance cost.
The utility model includes gas collection Water collecting tube and bracket, L shape discharge tube, pneumatic actuator；Gas collection Water collecting tube is hollow
Closed barrel, inside is without any mechanical device；The drainage tube for injecting gas drainage from coal seam is offered above cylinder lateral wall,
Glass reinforced plastic window is offered in the middle part of cylinder lateral wall, for observing water situation in tailrace；It is equipped with below gas collection Water collecting tube side wall
Dewatering outlet；L shape discharges water infratubal port on the dewatering outlet below gas collection Water collecting tube side wall, and rubber pad is equipped at upper port, prevents
Only the gas leakage of gas collection Water collecting tube or there is cinder to fall into；L shape discharge tube makes full use of law of connected vessels, the water surface in gas collection Water collecting tube
Height is higher by discharge tube upper end and pneumatic actuator when closing, and water can flow out automatically, until water surface elevation in gas collection Water collecting tube and
Discharge tube upper end is concordant.Gas collection Water collecting tube bottom end is equipped with slag-drip opening, if impurity blocks dewatering outlet too much in gas collection Water collecting tube
The deslagging lid that bottom end can be unscrewed carries out deslagging processing.Gas collection Water collecting tube bottom is cone shape, in order to deslagging.Gas collection collection
Water drum top is equipped with pneumatic actuator, releasing pipe is equipped with above pneumatic actuator, for connecting main mash gas extraction pipeline, releasing pipe
Pneumatic actuator model GT52 between gas collection Water collecting tube, for controlling the pressure in gas collection Water collecting tube.At cylinder body bottom
Equipped with the bracket convenient for placing.
Device it is set-mounted it is good after, main methane gas extraction pipeline is connected on the releasing pipe at the top of gas collection Water collecting tube, will be put
Hydrophone side wall drainage tube inject coal seam in carry out gas drainage, the impurity such as gas and water, coal, stone in coal seam can together into
Enter in tailrace gas collection Water collecting tube, in whole process, the buffer unit that tailrace catchments as gas collection, by coal seam water and
Impurity etc. is trapped in gas collection Water collecting tube and exhausts through dewatering outlet, slag-drip opening；Pneumatic actuator can be according to the time set
The connection of tailrace and main methane gas extraction pipeline is closed in timing, and after pneumatic actuator is closed, the negative pressure in gas collection Water collecting tube disappears,
As long as the height of water is more than L-type discharge tube upper end inside gas collection Water collecting tube, the pressure of water can open small rubber pad and realize and discharge water,
Extra water can be discharged into tunnel.In gas collection Water collecting tube when anhydrous or water very little, rubber pad can seal, and protect
Negative pressure needed for demonstrate,proving gas drainage.When water reach a certain height, the water in discharge tube plays sealing function, and rubber pad also can
Prevent the dirts such as cinder from entering in tailrace.
The automatic draining time controlled by pneumatic actuator is adjusted according to the size of coal seam water, and water obviously subtracts
The longer efficiency for discharging water and being spaced to guarantee gas drainage can be set when few.
For the utility model compared with other tailraces, structure is simple, without other extra devices such as buoy in tailrace.It is main
Wanting structure is that hollow closed gas collection catchments cylinder, not complicated mechanical structure.It is discharged water using law of connected vessels, when water reaches
Certain altitude meeting automatic draining, situations such as will not generating blocking or can not discharge water, the effect that discharges water is good.Timing automatic draining, can be with
Discharge time interval is set, is operated again without personnel after installation and debugging, labour post is reduced, reduces labor intensity.It can basis
The size of coal seam water and the duration of extraction set discharge time interval length, and gas drainage efficiency is made to reach maximization.
Be not in gas leakage problem during discharging water, security risk is not present.It is discharged water using law of connected vessels, mechanical structure letter
It is single, it is hardly damaged, a little repair, saves a large amount of maintenance costs.With visual window and slag-draining device, it is ensured that tailrace operation
Normally.
