Abstract
The invention discloses a high-temperature-resistant draught fan. The high-temperature-resistant draught fan is composed of a motor, an impeller device, a transmission shaft and a bearing pedestal which are arranged on a machine base. The transmission shaft is a hollow transmission shaft. The hollow transmission shaft is hollow inside. A shaft body is provided with a plurality of air inlets and a plurality of air outlets. The air outlets are formed in the portion, close to one end of the impeller device, of the wall of the shaft body. The hollow transmission shaft penetrates the bearing pedestal to be connected with the motor and the impeller device. During work, the motor rotates to drive the hollow transmission shaft to rotate, air around the hollow transmission shaft enters the hollow transmission shaft from the air inlets in the rotating process and then flows out of the air outlets, gas flow circulation is formed through the whole hollow inner portion of the hollow transmission shaft in the process, and therefore heat on the transmission shaft is brought away, the cooling effect is achieved, the temperature transmitted to the motor can be low enough, and it can be avoided that the motor is damaged when the temperature exceeds the maximum temperature capable of being borne by the motor.

Embodiment
Embodiment 1:
As shown in Fig. 1-Fig. 7: a kind of resisting blower is by the motor 1 be arranged on support, impeller unit 2, transmission shaft and bearing support 3 are formed, transmission shaft is Hollow Transmission Shafts 4, described Hollow Transmission Shafts 4 inner hollow, axis body has some intake grills 5, exhaust outlet 6, exhaust outlet 6 is opened on the axis body wall of impeller unit 2 one end, Hollow Transmission Shafts 4 connects motor 1 and impeller unit 2 through bearing support 3, described exhaust outlet 6 is air outlet hole 7, specifically distribute with plum blossom-shaped with 6 or 6 to 12 air outlet holes 7, described intake grill 5 is 24 inlet holes 8, every 4 is on the parallel axial plane being distributed in Hollow Transmission Shafts 4 of a vertical setting of types, Hollow Transmission Shafts 4 is provided with 2 or 2 to 4 volume air blades 9 and with the axis of Hollow Transmission Shafts 4 for axisymmetric distributes, volume air blade 9 cross section not with the axis perpendicular of Hollow Transmission Shafts 4, described inlet hole 8 aperture is 3mm, inlet hole 8 is arranged on the axial wall of blower fan one end, layout is plum blossom-shaped, volume air blade 9 has the uneven warping unilateral in blade in the edge of the one end near motor 1, the tangent plane of the unilateral and volume air blade 9 of volume air blade 9 and the point of contact of Hollow Transmission Shafts 4 forms angle of inclination, support is provided with safety guard plate 10, safety guard plate 10 is placed in above the volume air blade 9 of roll coil of strip air blade 9.
It is reasonable that the present invention saves blower fan structure, good cooling effect, keep motor side temperature not too high, motor durable, and work vibrates little portable type blower fan in running.
Embodiment 2:
As Fig. 8, Fig. 9, shown in Figure 10: the intake grill 5 on embodiment 1 hollow core transmission shaft 4 is galleyproof type fluting 11, the outward opening of described galleyproof type fluting 11 is greater than inner opening, described galleyproof type slots 11 quantity for two or more, such as four, the axis being parallel of galleyproof type fluting 11 and Hollow Transmission Shafts 4, galleyproof type 11 positions of slotting are that axisymmetric is offered with axis, therefore in Hollow Transmission Shafts 4, just air blade 9 and safety guard plate 10 is rolled up without the need to installing, increase the incoming air area of intake grill 5, thus overall increasing air output, can effectively improve air intake rate, do not need the assistance of rolling up air blade 9 simultaneously, just can reach the effect of cooling protection motor 1, and, after eliminating volume air blade 9, blower fan is overall normative strong and attractive in appearance, operating noise is little, the effects such as safe and convenient.
A root Hollow Transmission Shafts 2 is had between motor of the present invention and blower fan, 4 apertures can be devised near motor one end on axle, be arranged in a row, and pass straight through to the other end, two pieces of symmetries are devised and the contrary blade in direction above aperture, and in certain angle of inclination, when motor High Rotation Speed, flow of cooled air can be imported the motor side of hollow connecting shaft thus reach the object of cooling.
Band blade Hollow Transmission Shafts central hollow of the present invention, axle is designed with two sides blade, in opposite direction symmetry shape, has 4 apertures at corresponding blade arranged beneath.If power of motor is comparatively large, bearing can be made thicker and increase air draft hole, being designed with 6 air outlet holes, in plum blossom-shaped near blower fan one end.
Fan shaft pin of the present invention removes blade, and symmetry direction gets out rectangular nibs, Buddhism just to sense of rotation, its improvement after axle gauge model, attractive in appearance, noise is little than before a lot, has cooling function equally.
The present invention relates to a kind of resisting blower feature is be there is a Hollow Transmission Shafts between blower fan and motor.Devise 6 rounds at transmission shaft near blower fan one end, layout is plum blossom-shaped (according to the size of the size of power of motor and the suitable control hole of the thickness of axle and how many).8 holes are devised near motor one end, to be arranged in a row and symmetrical, above hole, to devise two pieces of symmetries and the contrary two pieces of volume air blades in direction, and have certain angle of inclination, when motor High Rotation Speed, flow of cooled air can be involved in the motor side of hollow connecting shaft.This resisting blower can extracting high-temperature air-flow, utilizes band blade hollow shaft that the heat of oil smoke can be stoped to reach motor side and is burnt out by motor.Convenient installation, noise is little, of many uses.Be commonly used to auxiliary chimney and derive air-flow.
The present invention saves fan motor and drives fan blade by transmission shaft, reaches the effect extracting oil smoke, has installed a safety guard plate outside transmission shaft, protects transmission shaft upper blade not hurt people when machine run.Whole machine is supported and fixed electrical machinery, transmission shaft and blower fan by a base.
Band blade Hollow Transmission Shafts, axle is designed with two sides blade, in opposite direction symmetry shape, has multiple hole at corresponding blade arranged beneath.6 air outlet holes are designed with, in plum blossom-shaped near blower fan one end.When motor runs at full speed, blower fan is driven by transmission shaft, a large amount of heat energy can be produced when blower fan time long operational time time, multiple aperture and blade is designed with in one end of Hollow Transmission Shafts, cool air is transferred to the other end blower fan place by the aperture below blade through hollow shaft, then discharges, according to blower fan size from 6 plum blossom-shaped holes of blower fan, power of motor adjusts the size of transmission shaft and eyelet, thus reaches the effect of cooling and prevention delivered heat.
