Abstract
The utility model discloses a spiral fan which is used as an exhaust fan, a wind exhaust fan, and a blower. The fan shaft of the spiral fan and spiral blades are made into an integral body. A fan flow guide pipe is arranged outside the spiral fan. A motor is installed on one end of the fan flow guide pipe, and a wind outlet is arranged on one end side. The other end of the fan flow guide pipe is a wind inlet, and a fan bearing seat is arranged in the wind inlet. The fan shaft and the spiral fan rotate at a high speed, thereby, rotary wind force similar to tornado is formed, therefore, wind quantity is large, and wind pressure is high. The wind quantity of the spiral fan is 1-1.5 times larger than the wind quantity of the usual vane type fan under the condition of the same diameter, and the wind pressure of the spiral fan is 1.5-2 times larger than the wind pressure of the usual vane type fan. The problem that the leakage of the vane type fan exists is overcome. The utility model has high efficiency, low energy consumption, novel structure, small noise, and light weight.
Description
The utility model is a kind of Spiral fan as exhausting, air draft, air blast.
The blower fan that uses is gone up in life at present and production, no matter as mechanical, electrical fan of pumping, ventilation or blower, generally be the blade type blower fan, its subject matter is that leakage is serious, so efficient is lower, for obtaining big air quantity, the diameter of blade is corresponding wants big, thereby the moment of torsion of blade is increased, and weight and volume also increases thereupon, and energy consumption strengthens.The general noise of this blower fan is also big, can not satisfy the requirement of people to blower fan.
The purpose of this utility model provides that a kind of air quantity is big, blast is high, the Spiral fan of the novel structure that energy consumption is low, noise is little.
The utility model is achieved in that Spiral fan is by motor, blower fan axle, spiral fan blade, honeycomb duct, bearing fan constitute, blower fan axle that links to each other with motor shaft and spiral fan blade are made an integral body, the spiral fan blade can be provided with one the circle or one the circle more than, the spiral fan blade of a spiral or an above spiral also can be set, its outer blower fan honeycomb duct that is equipped with, honeycomb duct one end is installed motor, the distolateral exhaust outlet that is provided with, end is intake grill in addition, wherein be equipped with bearing fan, make the blower fan axle fix and can rotate freely.
This Spiral fan is with honeycomb duct because blower fan axle and spiral fan blade are made an integral body outside it, constitute the continuous pressurization of blower fan, has overcome the leakage serious problems that general blade type blower fan exists.Because the high speed rotating of blower fan axle, the spiral fan blade is with same high speed operation, thereby form the rotation wind-force of similar tornado, suction is very big, thereby fan delivery is big, and blast height, blast are directly proportional with the number of turns of fan blade, can decide the number of turns according to required blast, under the identical situation of blower fan diameter, the air quantity of Spiral fan is greater than 1～1.5 times of blade type blower fan, and blast is big 1.5～2 times.Under the suitable situation of air quantity, the diameter of Spiral fan is little, and the moment of torsion of fan blade is also little, therefore energy consumption is low, the efficient height, and volume is little, in light weight, novel structure is easy to make, and can be used for the down-hole, mine, smelt, logical, the air draft in the places such as laboratory of universities and colleges and factories and miness also can be used as the air bells exhauster of range hood, are specially adapted to logical, the air draft in the serious place of dust.And can be designed to the blower use, be a kind of product of update.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural drawing of Spiral fan
Fig. 2 is the plan view of bearing fan
With reference to Fig. 1, Spiral fan is made of motor (3), blower fan axle (7), spiral fan blade (8), honeycomb duct (9) and bearing fan (19).Motor (3) is with annular fixed plate (12) location, and by three fixing bolts (4) with nut (1) with after adjusting nut (2) and fixing, be installed in again on the upper cover plate (6) of honeycomb duct (9).The output axle head of motor (3) and blower fan axle head (7) are all made hexagon, and overcoat is connected to each other with the connecting sleeve (5) with hexagonal internal bore.Blower fan axle (7) locates to be with copper sheathing (16) and rubber seal (17) at upper cover plate (6), blower fan axle (7) is made an integral body with spiral fan blade (8), the spiral fan blade can be provided with one the circle or one the circle more than, this example is provided with 3 circles, the spiral fan blade of a spiral or an above spiral also can be set, blast is directly proportional with the number of turns of fan blade, can design the number of turns according to required blast.The angle of spiral fan blade and blower fan axle (7) is 20～60 degree, and fan blade (8) is flat, and its periphery has the crimping of 3m/m * 45 degree slightly.The upper end side of honeycomb duct has exhaust outlet (15), the lower end is an intake grill, wherein be equipped with bearing fan (19), it is by copper sheathing (18), steel ball (11), adjustment screw rod (23), the axle sleeve (13) of hold-doun nut (20) and band muscle constitutes, and adjusts the height that screw rod (23) can be regulated steel ball (11).Axle sleeve (13) has tibet cinnamon bark, and it and honeycomb duct (9) use bolt (22) fastened to each other.This Spiral fan during as the air bells exhauster of range hood, is then fixed one and drawn cover (24) in honeycomb duct (9) lower end, cover (24) top has an outer shroud (10) and back oil ring (21), bearing support (19) with draw cover (24) in and can be made of one.This Spiral fan also can be used as the induced draft fan of vacuum cleaner, and also can directly be designed to the output shaft of motor have the blower fan axle of spiral fan blade this moment, and with simplified structure, this structure of dust collector is simple, and cost is low.
Claims (3)
1, a kind of Spiral fan as exhausting, air draft, air blast, it comprises a motor, it is characterized in that the blower fan axle (7) that links to each other with motor shaft and spiral fan blade (8) make an integral body, spiral fan blade (8) can be provided with one the circle or one the circle more than, the spiral fan blade of a spiral or an above spiral also can be set, its outer blower fan honeycomb duct (9) that is equipped with, honeycomb duct (9) one ends are installed motor, and distolateral other end of exhaust outlet (15) that is provided with is equipped with bearing fan (19).
