Abstract
The utility model reequips collection device for a kind of feeder gas, solve existing feeder dustpan rear end and taper chute connecting portion, easily form a cavity dead angle, cause the accumulation of gas and extraction inconvenience, there are the problem of larger security risk, including gas collecting hood and transition pipe, one end of collecting hood is horn mouth, one end is square tube, horn mouth is fixed in feeder main body, square tube is connected with transition pipe one end, and the transition pipe other end is connected with main air draft road, and main air draft road is connected with exhaust fan.The utility model between feeder and main air draft road by setting gas collection device so that the discharge of gas is safer, and the utility model is simple in structure, and cost performance is high, easy to utilization and extention.
Description
Technical field
Technical field of coal mine equipment is the utility model is related to, is specially a kind of feeder gas repacking collection device.
Technical background
Feeder is as the charging gear that raw coal is discharged under run coal bin, and the gas contained in feeding process, coal is with coal stream
Operation is drifted everywhere, is fixed in feeder dustpan rear end with storehouse cylinder feeding chute junction using air duct fabric, but existing
Cavity can be occur methane accumulation the problem of during to coal.Detection gas index in air duct fabric is stretched into by optics watt inspection instrument
9% or so, and air duct fabric is damaged, and field portable watt inspection instrument test gas index can reach more than 0.7%, and there are great peace
Full hidden danger.
Existing feeder is made into coating base fabric frequently with high-strength jewel fiber, and PVC is modified as skin covering of the surface
Main material of the air duct fabric as ventilating duct, and it is processed into tubular or square tube type directly uses, in feeder dustpan rear end
With taper chute connecting portion, a cavity dead angle is easily formed, causes accumulation and the extraction inconvenience of gas, there are larger safety is hidden
The situation of trouble, detection research finds because the structure of guide duct it is single and caliber is relatively narrow can not be clean by gas exhaust, if single
Pure increasing caliber, but because pressure is too small so that pump drainage effect is undesirable.
The content of the invention
The utility model easily forms a cavity to solve existing feeder dustpan rear end and taper chute connecting portion
Dead angle, causes accumulation and the extraction inconvenience of gas, there are the problem of larger security risk, there is provided a kind of feeder gas repacking
Collection device.
The utility model is achieved by the following technical solution：A kind of feeder gas repacking collection device, including watt
This collecting hood and transition pipe, one end of gas collecting hood is horn mouth, and one end is square tube, and horn mouth is fixed on feeder main body
On, square tube is connected with transition pipe one end, and the transition pipe other end is connected with main air draft road, and main air draft road is connected with exhausting
Machine.
Gas collecting hood is using made of stainless steel iron sheet or air hose cloth.
Gas collecting hood is provided with fluid sealant with feeder main body junction outer surface.
Square tube is both provided with fluid sealant with transition pipe and transition pipe and the junction on main air draft road.
Feeder dustpan rear end increases the gas collection device of the utility model, wherein horn mouth with taper chute connecting portion
It is connected with feeder, increases the contact area of collection device and feeder so that gas is not easy to be gathered in dead angle position, watt
The other end of this collecting hood uses rhs-structure, and the area of square tube is less than horn mouth area, and transition pipe is connecting square pipes and master
Air draft pipeline, its length can be configured as needed, and wherein transition pipe and square tube and main air draft road can be very
Good mating connection so that the moderate pressure of pump drainage, by fixed exhausting, can naturally drain gas, further watt
This collecting hood and feeder main body junction, square tube and the junction of transition pipe and transition pipe and the company on main air draft road
The equal injection fluid sealant in place is connect, ensures that gas is not revealed during pump drainage.
Wherein, wind turbine and feeder are latching relation, i.e.,：Only feeder could be started after wind turbine unlatching, further
Strengthen the security performance of its discharge.
The utility model has the advantage that：By setting gas collection device between feeder and main air draft road, make
It is safer to obtain the discharge of gas, and the utility model is simple in structure, cost performance is high, easy to utilization and extention.
Brief description of the drawings
Fig. 1 is the schematic view of the mounting position of the utility model；
Fig. 2 is the structure diagram of the utility model.
In figure：1- gas collecting hoods, 2- transition pipes, 3- main air drafts road, 4- feeder main bodys.
Embodiment
The utility model is described further with reference to Fig. 1 and Fig. 2, a kind of feeder gas reequips collection device, including
Gas collecting hood 1 and transition pipe 2, one end of gas collecting hood 1 is horn mouth, and one end is square tube, and horn mouth is fixed on to coal
On owner's body 4, square tube is connected with 2 one end of transition pipe, and 2 other end of transition pipe is connected with main air draft road 3, main air draft road
3 are connected with exhaust fan.
Gas collecting hood 1 is using made of stainless steel iron sheet or air hose cloth.Gas collecting hood 1 and feeder main body 4
Junction outer surface is provided with fluid sealant.Square tube and transition pipe 2 and transition pipe 2 and the junction on main air draft road 3 are equal
It is provided with fluid sealant.
Wherein, 1 one end of gas collecting hood is horn mouth, and one end is square tube, and square tube can be substituted for the other pipelines such as pipe,
If replaced, transition pipe 2 and main air draft road 3 can accordingly convert.The conversion occurred in such cases is accordingly to be regarded as at this
Within the protection domain of utility model.
