Description
Technical field
The utility model relates to the technical field of local ventilation firedamp drainage in the underworkings of colliery, specifically is a kind of distinguished and admirable regulation device that is used for safety, simple firedamp drainage.
Background technology
In recent years, along with coal mining enterprise's high speed development, the coal production cumulative year after year, coal enterprise's technical equipment improves year by year, but this must be guarantee with safety.How effectively control is as the referred more and more higher status of No.1 hidden danger " gas " of Safety of Coal Mine Production.The driving face that the location is the portable blower air feed very easily takes place in fire damp, in case the driving face blowing-out will cause face gas to gather, and stops to produce, and has only face gas is discharged into below the normal concentration and just can produce.The air duct that begins to unsnap for not transfiniting from gas of firedamp drainage method in the past binds air duct, controls method such as blower fan inlet scoop with plank and control air quantity and carry out firedamp drainage by joint discharging or with rope.Wherein, safer by the joint exhaust method, connect but must take air duct again apart, workload is big, and information is difficult for transmitting in the discharge process; Regulate air quantity with rope or plank control air quantity for adding resistance, the ventilation fan working resistance is increased, and wayward.
Summary of the invention
Problems such as the utility model is big for the workload that solves the used drawing-off gas method existence of present down-hole driving face, control is difficult for provide a kind of distinguished and admirable regulation device.
The utility model is to adopt following technical scheme to realize: distinguished and admirable regulation device, comprise hard ventilating tube, and the tube end of hard ventilating tube is provided with and is used to the installed part of realizing that hard ventilating tube and down-hole air duct are connected and fixed; Offer branch air regulator mouth on the barrel of hard ventilating tube, and divide air regulator mouth place to be provided with drawing and pulling type window lid; Hard ventilating tube is provided with and is used to the suspender (being generally suspension ring) of realizing that hard ventilating tube and back install and fix; Hard ventilating tube is provided with the rotating shaft that runs through hard ventilating tube and radially be provided with along hard ventilating tube, and rotating shaft is single-ended to be provided with and to control the handle that rotating shaft is rotated, be fixed with in the rotating shaft place in the hard ventilating tube and with hard ventilating tube in the control aerofoil that is complementary of cross sectional shape radially.
During application, distinguished and admirable regulation device described in the utility model is arranged between booster and the tunnel return air inlet, apart from 1 meter of return air inlet, two ends link to each other with the down-hole air duct by installed part, and control aerofoil place side is in this side of tunnel return air inlet, divides air regulator mouth place side to be in this side of booster, can regulate intake by handle rotation control aerofoil, by the size that drawing and pulling type window lid draws back, the air quantity that can control directly discharge how much.Utilize the operating process of device firedamp drainage described in the utility model as follows: before the firedamp drainage, gas person at first checks the gas density in booster and 10 meters scopes of switch thereof, when gas density less than 0.5% the time, operating personnel divide the window lid of air regulator mouth all to extract out air devider, make control aerofoil sealing hard ventilating tube, the place has hung portable instrument at the tunnel return air inlet, after warning is established in the entrance that leads to this tunnel air return system, opens booster.After blower fan runs well, operating personnel progressively rotate the control aerofoil to the work plane air feed, until opening fully, and then progressively will divide the window lid of air regulator mouth to close, until the normal air feed of work plane, this stage gas person will observe portable instrument always, when portable instrument show value surpasses 1.5%, inform that immediately the electrician reduces face air volume, only be no more than at 1.5% o'clock at portable instrument show value, can slowly increase face air volume, finish until firedamp drainage.Therefore in whole drawing-off gas process, this device can by the size (unnecessary air quantity can be discharged through minute air regulator mouth) that adjusting enters face air volume, carry out safety dumping gas under the situation that does not change windage, avoid cancelling all things together.
Compared with prior art, the utlity model has following beneficial effect: 1. distinguished and admirable control is reliable, can regulate portable blower arbitrarily to work plane wind supply quantity (arriving between the maximum wind supply quantity of portable blower zero); 2. this device is simple to operate, and operating personnel need not possess higher educational level, is fit to the low situation of current underground labour's educational level; 3. need not during firedamp drainage to reduce labour intensity by the joint air duct of unsnaping; 4. the discharge process personnel all to be in big system exhaust ventilation district safer; 5. the information transmission strengthens the safety of firedamp drainage accurately, rapidly.
The utility model is simple and reasonable for structure, and result of use is good, and labour intensity is low, and control is reliable.
