Abstract
Distance dust emission equipment is composed of a dust-absorbing opening, a hard air duct, a drawout dedusting blower fan and a dust emission opening. The hard air duct is an integral hollow cylindrical structure and is a main body member of the equipment; one end of the hard air duct is the dust-absorbing opening and the other end of the hard air duct is the dust emission opening; and the drawout dedusting blower fan is arranged in the dust emission opening. The basic principle of the equipment is that dust emission is carried out in a manner that the distance between an air outlet of a forced local ventilator and a dust generating point is controlled and a pumping fan is used. Tests have proved that the distance dust emission equipment solves a problem that a driver of a heading machine is influenced by dust; the dust can be directly emitted away from the influencing scope of the working area of the driver in a manner that the distance between an air outlet of a forced local ventilator and a dust generating point is controlled; and a good working environment is provided to the driver of the heading machine, so that the significance in safety production and personal safety is provided. The distance dust emission equipment is simple in structure, convenient in operation and good in stability and reliability, so that work efficiency is increased and safety heading is ensured.
Description
Technical field
The utility model relates to mine dust exhausting equipment, relates in particular to the spacing formula dust exhausting equipment that uses under the coal mine.
Background technology
The down-hole dust discharge is the basic work of Safety of Coal Mine Production, usually all adopt for the dust that is produced during mine laneway or chamber driving and fall after the mist dust arrester carries out depositing dust, with forced booster dust is discharged, the method is for not influenced by operating environment, particularly the little operating location of operating personnel's sight line influence is produced effect, but development machine driver operation place is near apart from producing dirt pits at present, the spray stream that produces during the wet type depositing dust makes the dust motion be tending towards disorderly more, dust at development machine driver operation place does not obviously reduce, not only influence development machine driver's sight line, also can influence its job scheduling and workmanship, especially have a strong impact on field operation personnel's personal safety.Generally wet dust removal can form spray stream, causes the dust motion disorderly, influences development machine driver sight line, simultaneously development machine driver health of human body is produced harm, the easy anthraco-silicosis that gets.According to standard-required, the supply channel hydraulic pressure that need prevent dust during wet dust removal reaches certain pressure, and along with prolongation or other factor affecting of digging laneway distance, hydraulic pressure can't reach requirement sometimes, can't atomize to current.
The utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of spacing formula dust exhausting equipment is provided, and the high efficiency dust discharge of carrying out by distance between control pump drainage formula dedusting fan and the forced booster is applicable in the process of mine large section roadway or chamber driving.
Spacing formula dust exhausting equipment described in the utility model includes suction port, hard ventilating tube, pull-out type dedusting fan and dust-exhausting port and forms.The whole hollow tubular structure of hard ventilating tube is a main component of the present utility model, and an end of hard ventilating tube is a suction port, and the other end of hard ventilating tube is a dust-exhausting port, in said dust-exhausting port, is provided with the pull-out type dedusting fan.Spacing formula dust exhausting equipment described in the utility model, its basic principle are exactly by the forced booster air outlet of control and produce distance between the dirt pits, utilize the pump drainage blower fan suction port that is arranged at the product dirt pits that dust is discharged simultaneously.Through evidence, spacing formula dust exhausting equipment has solved the problem that the development machine driver is influenced by dust, by controlling the distance between forced booster air outlet and the product dirt pits, dust directly can be discharged outside the influence basin of its working region, for the development machine driver provides the good working environment, significant to safety in production and personal safety.Spacing formula dust exhausting equipment described in the utility model is then by forced fan outlet of control and pull-out type dedusting fan pump drainage mouth distance, make it form certain pressure reduction space, directly the dust that produces is discharged outside the influence basin of its working region, improved development machine driver's working environment greatly, especially spacing formula dust exhausting equipment can not be subjected to influence of hydraulic pressure just can directly carry out dust discharge.
Spacing formula dust exhausting equipment described in the utility model, overall structure is simple, and is easy for operation, good stability, the reliability height can be guaranteed the dust removing effects of working site, guarantees normally carrying out and personal safety of work.
Description of drawings
Accompanying drawing 1 is the structural representation of spacing formula dust exhausting equipment described in the utility model.1-suction port, 2-hard ventilating tube, 3-pull-out type dedusting fan, 4-dust-exhausting port.
The specific embodiment
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: spacing formula dust exhausting equipment described in the utility model includes suction port 1, hard ventilating tube 2, pull-out type dedusting fan 3 and dust-exhausting port 4 and forms.Hard ventilating tube 2 whole hollow tubular structures are main components of the present utility model, and an end of hard ventilating tube 2 is suction ports 1, and the other end of hard ventilating tube 2 is dust-exhausting ports 4, in said dust-exhausting port 4, is provided with pull-out type dedusting fan 3.Spacing formula dust exhausting equipment described in the utility model, its basic principle are exactly by the forced booster air outlet of control and produce distance between the dirt pits, utilize the pump drainage blower fan suction port 1 that is arranged at the product dirt pits that dust is discharged simultaneously.Through evidence, spacing formula dust exhausting equipment has solved the problem that the development machine driver is influenced by dust, by controlling the distance between forced booster air outlet and the product dirt pits, dust directly can be discharged outside the influence basin of its working region, for the development machine driver provides the good working environment, significant to safety in production and personal safety.Spacing formula dust exhausting equipment described in the utility model, then by forced fan outlet of control and pull-out type dedusting fan pump drainage mouth distance, make it form certain pressure reduction space, directly the dust that produces is discharged outside the influence basin of its working region, improved development machine driver's working environment greatly, especially spacing formula dust exhausting equipment can not be subjected to influence of hydraulic pressure just can directly carry out dust discharge.Spacing formula dust exhausting equipment described in the utility model, overall structure is simple, and is easy for operation, good stability, the reliability height can be guaranteed the dust removing effects of working site, guarantee normally carrying out and personal safety of work, improved operating efficiency, guaranteed safe driving.
Claims (1)
