Abstract
The utility model discloses a kind of mining noise reduction fans, including shell, inner casing, current collector and motor, noise reduction object is filled between the shell and inner casing, the motor is fixed on by motor fixing shaft in inner casing, the motor front-end and back-end are separately installed with preceding impeller and rear impeller, the inner casing front end is equipped with current collector, and the current collector front end is equipped with filter screen, air inlet is equipped with before the filter screen.It the advantage is that：For the utility model by installing slide plate in wind turbine bottom, manpower has been saved in the carrying during being easy to use in tunnel；By installing bilobed wheel in blower interior, the pressure of wind turbine is increased, improves the air quantity of wind turbine；By, filled with noise reduction object, effectively reducing noise, it is therefore prevented that injury of the noise to human body inside wind turbine inner casing and shell and rectification cap.
Description
Technical field
The utility model belongs to mine ventilator field, and in particular to a kind of mining noise reduction fans.
Background technology
Wind turbine is widely used in the ventilation, dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, ship and building；
The ventilation of boiler and industrial furnace and air inducing；Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance；The baking of cereal
It does and selects and recommends；Inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..The operation principle of wind turbine and turbocompressor are essentially identical, only
It is since gas flow rate is relatively low, pressure change is little, generally the variation without the concern for gas specific volume, i.e., using gas as can not
Compression fluid processing.
Domestic mine fan is substantially to be generated in the relatively closed space use of underground coal mine, normal operation
Noise easily makes tinnitus, dizziness, weakness of limbs and the symptoms such as absent minded occur in the miner of underground work for a long time, to ore deposit
The damage of work body is serious；Simultaneously because in metal mine exploitation at present, drift section is all smaller, and the pipeline of air-supply all cannot
Using larger-diameter air hose, have a very big difficulty to safe air feed, existing quo of local Fan for Mine only have one group of impeller and
Guide vane, wind pressure is small, can not realize the safe air feed in the tunnel lack of standardization in metal mine digging.Therefore, it is necessary to research and develop one kind to make an uproar
The mine ventilator that sound is small, resistance is small, air quantity is larger.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide that a kind of noise is small, resistance is small, air quantity is larger
Mining noise reduction fans.
The technical solution adopted in the utility model is：A kind of mining noise reduction fans, including shell, inner casing, current collector and electricity
Machine, innovative point are：It is fixed on by motor fixing shaft interior filled with noise reduction object, the motor between the shell and inner casing
In shell, the motor front-end and back-end are separately installed with preceding impeller and rear impeller, and the inner casing front end is equipped with current collector, described
Current collector front end is equipped with filter screen, and air inlet is equipped with before the filter screen.
Further, the outer casing bottom is equipped with slide plate.
Further, the current collector outer end is to the horn-like of outer arcuate opening, is fixed with inside the current collector whole
Cap is flowed, the rectification cap is hemispherical configuration of the cambered surface towards current collector, and noise reduction object is filled with inside the rectification cap.
The beneficial effects of the utility model are as follows：
（1）The utility model by installing slide plate in wind turbine bottom, save by the carrying during being easy to use in tunnel
Manpower；
（2）The utility model increases the pressure of wind turbine, improves the wind of wind turbine by installing bilobed wheel in blower interior
Amount；
（3）The utility model inside wind turbine inner casing and shell and rectification cap by being filled with noise reduction object, effectively
Reduce noise, it is therefore prevented that injury of the noise to human body.
Description of the drawings
The utility model is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
As shown in Figure 1, a kind of mining noise reduction fans, including shell 1, inner casing 2, current collector 4 and motor 3, shell 1 and inner casing
It is fixed between 2 filled with noise reduction object 12, motor 3 by motor fixing shaft 10 on inner casing 2,3 front-end and back-end of motor are pacified respectively
Equipped with preceding impeller 5 and rear impeller 6, the pressure of wind turbine is increased, improves the air quantity of wind turbine, 2 front end of inner casing is equipped with current collector
4,4 front end of current collector is equipped with filter screen 7, and air inlet 8 is equipped with before filter screen 7.
1 bottom of shell is equipped with slide plate 11, convenient for the carrying during wind turbine use in tunnel, has saved manpower.
4 outer end of current collector is to the horn-like of outer arcuate opening, rectification cap 9 is fixed with inside current collector 4, rectification cap 9 is
For cambered surface towards the hemispherical configuration of current collector, 9 inside of rectification cap is filled with noise reduction object 10.
The utility model inside wind turbine inner casing 2 and shell 1 and rectification cap 9 by being filled with noise reduction object 10, effectively
Reduce noise, it is therefore prevented that injury of the noise to human body.
The above is the preferred embodiment of the utility model, it is impossible to the right model of the utility model is limited with this
It encloses.It should be pointed out that for those skilled in the art, modify to the technical solution of the utility model or
Person's equivalent substitution, without departure from the scope of protection of the utility model.
