The first fan body is connected with the second fan body. Motors are installed inside the first fan body and the second fan body respectively, and are opposite in rotation direction. Impellers are installed at the top ends of the motors, the inlet air noise elimination nets are symmetrically installed at the side end of the first fan body and the side end of the second fan body, the noise elimination layer is installed at the position where the first fan body is connected with the second fan body, the foot frame is installed at the bottom ends of the first fan body and the second fan body, and the pipe orifices are formed in the top end of the first fan body and the top end of the second fan body respectively. The mine fan is simple in structure, convenient to use and obvious in effect; the first fan body and the second fan body can be well used for ventilation and are high in ventilation efficiency, a protection cover is used for preventing the fan from being damaged, the service life of the fan is prolonged, the inlet air noise elimination nets and the noise elimination layer can eliminate noise, the noise elimination efficiency is improved, and the fan can work more safely and reliably.
Description
Technical field
The utility model is specifically related to a kind of mine fan, belongs to industrial instrument field.
Background technique
Mine fan can be used for ventilation in mining industry work, dustproof and cooling, mine fan is to use under coal mine mostly, because its space is relatively airtight, so noise can not effectively radiate, reflecting background is large, causes miner personnel to bear larger noise pollution.Existing mine fan ventilation effect is bad, and noise control is to increase import silencing apparatus at impeller and front and back substantially, and import silencing apparatus is subject to the restriction of geographical conditions under coal mine, can not be widely used, and manufacture cost is higher, and noise eradicating efficacy is poor.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of low noise, and the good mine fan of ventilation effect.
Mine fan of the present utility model, comprises the first blower fan, the second blower fan, air intake silencing net, silencing plate, foot rest and the mouth of pipe; Described the first blower fan is connected with the second blower fan; Described the first blower fan and the second blower fan inside are provided with motor, and motor steering is contrary; Described motor top is provided with impeller; Described air intake silencing net symmetry is arranged on the first blower fan and the second blower fan side; Described silencing plate is arranged on the first blower fan and the second blower fan joint; Described foot rest is arranged on the first blower fan and the second blower fan bottom; The described mouth of pipe is placed in respectively the first blower fan and the second blower fan top.
Further, in described silencing plate, be filled with the cotton of eliminating the noise.
Further, described impeller is set to arcuate structure.
Further, described the first blower fan and the second blower fan are provided with protecting crust outward.
Further, described air intake silencing net front end is provided with protective net.
The utility model beneficial effect: the utility model is simple in structure, easy to use, successful, the first blower fan and the second blower fan can perform well in ventilating, and drafting efficiency is high, use protecting crust can prevent that blower fan from damaging, improve the working life of blower fan, and air intake silencing net and silencing plate can be convenient to eliminate noise, improve acoustical absorptivity, make ventilator work more safe and reliable.
