Abstract
The utility model relates to a special purpose combined axial ventilator for a small mine. The draught fan, the electric motor, and the control disc of the ventilator which are integrated are fixed onto a crow plate-shaped machine frame; the v-belt transmission makes an impeller to rotate; the wheel hub ratio is 0.5, and the taper sleeve and the key connection are adopted between the wheel hub and the shaft, and between the belt wheel and the shaft. The utility model which has the advantages of convenient maintenance, small size, easy installation, easy transport, and large adjustable range is suitable for the features of the small-size mine on the aspects of the air pressure and the air quantity. The benefit of the safe production of the small-size mine can be improved, and the matched equipment of the small-size mine can be perfected.
Description
The utility model relates to a kind of special-purpose assembly type propeller fan of small mine that is exclusively used in.
The ventilation of small mine does not have special-purpose ventilator, and most of dependence natural ventilation substitutes ventilator and can not satisfy the characteristics that the small mine blast is little, air quantity is big.
The purpose of this utility model is to provide a kind of assembly type propeller fan that is exclusively used in small mine.This ventilator adapts to the characteristics that the small mine blast is little, air quantity is big.
The special-purpose assembly type propeller fan of the utility model small mine is a kind of horizontal package assembly.The integral body of this ventilator is the horizontal assembly body with the v belt transmission mechanical, electrical, the instrument one, its blower fan, motor, control panel all can be fixed on the skid plate type frame, but motor also riding suit on the main body air duct, the hub ratio of this ventilator is 0.5, the air duct of blower fan, diffuser, wind collecting unit portion, wheel hub are an all-welded structure, and the v belt drive part of ventilator is equipped with an easy-disassembling-assembling aerial belt every cover.Its active part can be extracted out from standing part, connects wheel hub and axle with tapered sleeve and key connecting mode, and with similar mode connecting belt wheel and axle.
The utility model can be realized by following proposal.Blower fan, motor, control panel are that unitary fixed is assembled on the skid plate type frame, particularly with the motor riding suit on the main body air duct, make the impeller rotation by the v belt transmission, rotation speed of fan n＞1000 rev/min, be convenient to fan speed regulation, enlarge Applicable scope, convenient installation, maintenance and replacing standby fan.The ladder type that 12 glass fibre reinforced plastics make is housed on the impeller twists not uniform thickness wing blades, the established angle of blade is adjustable in 15 °-45 °, to adapt to the requirement of the different operating modes of positive and negative wind direction.The all-welded structure of complete machine has guaranteed that complete machine is in light weight, is convenient to transportation, installs.In order to reduce belt every the influence of cover to Flow area, adopt the belt housing of hollow structure, its active part can be extracted out from standing part, so that change belt.Wheel hub and axle adopt tapered sleeve and key connecting between belt pulley and the axle, axially open a groove at the tapered sleeve edge, make it have certain elasticity, and dismounting is very convenient.
Enforcement of the present utility model, having changed small mine does not have the situation of special-purpose ventilator, be small mine, particularly the safety in production in the little colliery below 90,000 tons has brought great benefit, this ventilator structure compactness, in light weight, assembling easily, and is applied widely, energy-conservation economize on electricity, install, convenient transportation, the perfect corollary equipment of small mine.
The drawing of accompanying drawing is described as follows:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model belt housing schematic representation.
Accompanying drawing 3 is the utility model tapered sleeve and key connection diagram.
As shown in Figure 1, blower fan adopts horizontal type structure, axial combined body air duct (3), wind collecting unit portion (1), rear guide vane portion (4) and diffuser (5).The frame (7) that is contained in motor goes up or rides on the main body air duct (3), makes belt pulley (6), axle, impeller (2) rotation by v belt, and skid plate (8) is used for fixing blower fan.
Be the belt housing of hollow structure as shown in Figure 2, (9) active part for twitching, (10) are standing part.
As shown in Figure 3, wheel hub (11) is enclosed within on the tapered sleeve (12), is connected with axle (14) by key (13).
Claims (5)
1, the special-purpose axial fan of a kind of small mine of horizontal package assembly is characterized in that: the integral body of a. ventilator is the horizontal package assembly of the v belt transmission of mechanical, electrical, instrument one.
B. the air duct of complete machine, diffuser, wind collecting unit portion, wheel hub are an all-welded structure.
C. easy-disassembling-assembling aerial belt is every cover.
D. use the wheel hub and axle of tapered sleeve and key connecting.
2, ventilator according to claim 1 is characterized in that blower fan, motor, control panel all can be fixed on the skid plate type frame, but motor also riding suit on the main body air duct.
3, ventilator according to claim 1 is characterized in that hub ratio is 0.5.
4, ventilator according to claim 1 is characterized in that the active part of hollow v belt cover can be extracted out from standing part.
5, ventilator according to claim 1 is characterized in that belt pulley and axle can also wheel hub and spool similar mode tapered sleeve and the key connecting that connect.
