Abstract
The utility model discloses an explosion-proof axial-flow ventilator for the mine. The improvement of the utility model is that a blade wheel is connected with a motor directly. The motor is installed in the shell of the motor. The flange connection is adopted among a current collecting device, a new wind current shell, a motor shell and a diffuser evenly. The new wind current shell is composed of a new wind current barrel body, a plurality of wing type current channels and a current guiding body. An explosion-proof blade is manufactured by cast aluminium outside a steel core. The wind quantity of the explosion-proof blade is high, and the power consumption of the explosion-proof blade is small. The wind quantity of the explosion-proof blade can be adjusted between 20 DEG-32 DEG according to the wind quantity to be required by mine wells. The utility model has the advantages of compact structure, convenient installation, high efficiency and low noise. The utility model can save a large number of expenses for the raw materials and the processing.
Description
The utility model relates to a kind of improvement of explosion-proof mining propeller fan.
As everyone knows, mine ventilation is the delivered downhole fresh air, scavenges, and the condition of regulating the climate, guarantee safety of workers health realize the important measures of safe and efficient production.But existing mining propeller fan all can not adapt to the needs of required air quantity of mine and blast, the volume of ventilator is big, operational efficiency is low, power consumption is many, found a capital construction, installation, maintenance, processing and raw materials consumption of well is very big, and especially middle-size and small-size Township Coal Mine ventilated environment is poor, and it is serious to lack wind, accident constantly takes place, and causes very big loss for people's life and national wealth.
The purpose of this utility model is exactly for overcoming the mining propeller fan of a kind of new type explosion proof that the deficiencies in the prior art part provides.
The explosion-proof mining propeller fan of the utility model still comprises motor, blade, wheel hub, housing etc., and its improvement is that impeller directly is connected on the motor shaft, has dwindled the volume of ventilator, and motor is installed in the electric machine casing.Slip ring, new distinguished and admirable housing, electric machine casing all adopts flange to connect between diffuser.New distinguished and admirable housing is by new distinguished and admirable cylindrical shell, a plurality of aerofoil profile runner, and deflector is formed.One end of aerofoil profile runner and new distinguished and admirable cylindrical shell are welded to connect, and the other end and deflector are welded to connect.The blade handle is fixed on the impeller boss, and its blade angle can be regulated according to mine institute required airflow between 20 °-32 °.Blade is made with the outer cast aluminium of steel core.
The utility model is described in further detail below in conjunction with accompanying drawing:
Figure one is the explosion-proof mining propeller fan structural representation of the utility model.
Figure two is the new distinguished and admirable housing front view of the utility model.
Figure three is the new distinguished and admirable case side view of the utility model.
Label declaration: 1, slip ring 2, new distinguished and admirable housing 3, electric machine casing 4, diffuser 5, motor 6, wheel hub 7, blade 8,12, fresh air intake 9, motor prop up grillage 10, support 11, motor air guide sleeve 13, new distinguished and admirable cylindrical shell 14, aerofoil profile runner 15, deflector
10 is support in the accompanying drawing, support 10 is one with electric machine casing 3 welderings, motor 5 props up grillage 9 with motor and packs in the electric machine casing 3, electric machine casing 3 is connected with new distinguished and admirable housing 2 flanges, make motor 5 running work in the fresh wind space that new distinguished and admirable housing 2 is introduced, flammable filthy wind flings the possibility that motor 5 sets off an explosion in having ended the mine that contains methane, fresh air is from the fresh air intake 8,12 enter, enter deflector 15 through aerofoil profile runner 14, send into motor air guide sleeve 11 by motor ventilating fan, the heat that motor 5 is distributed enters dirty distinguished and admirable, and it is good to make motor 5 have Safety performance, meets the safety regulations in coal mine requirement.Diffuser 4 and electric machine casing 3 are connected by flange.New distinguished and admirable housing 2 is made up of new distinguished and admirable cylindrical shell 13, aerofoil profile runner 14, deflector 15.One end of aerofoil profile runner 14 and new distinguished and admirable cylindrical shell 13 are welded to connect, and the other end and deflector 15 are welded to connect.Blade 7 is made with the outer cast aluminium of steel core, the blade handle is fixed on the impeller boss, blade 7 is connected with impeller boss 6 bolts, the angle of blade 7 can be regulated by the needs according to mine institute's required airflow and blast between 20 °-32 °, make blower fan all the time in the operation of efficient district, thereby saving electric power, well are built investment and maintenance expenses.
The advantage of the utility model explosion-proof axial-flow ventilator for mine is: compact conformation is easy, be convenient to installation, power consumptive province, efficient height, noise is low, easy to maintenance, explosion-proof performance is good, can save a large amount of raw material and processing charges.
