Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the drawings and specific embodiments, further set forth the utility model.
Fig. 1 is the plan view of air exhauster of the present utility model; Fig. 2 is a left TV structure schematic representation of the present utility model; Fig. 3 is a plan view of the present utility model; Fig. 4 is that A-A among Fig. 3 is to the sectional structure schematic representation; Fig. 5 is an internal structure cut-away diagram of the present utility model; Fig. 6 is the stereogram of air exhauster of the present utility model.
Air exhauster of the present utility model, comprise housing 1, motor 5, electric machine support 11, seal ring 8, seal ring fixed support 9 and blade 7, housing 1 is cylindric, is made up of inwall 3 and outer wall 2, form air channel 4 between inwall 3 and the outer wall 2, described air channel 4 is the three-back-shaped of both ends open up and down.The air duct of both ends open up and down of housing 1 can make air circulate in air channel 4.In the cavity that forms in the middle of the inwall 3, be provided with electric machine support 11, the two ends of electric machine support 11 are fixed on the outside of inwall 3, motor 5 is suspended on the electric machine support 11, and motor shaft reaches in the air channel, upper end 4 of housing 1 by the inwall 3 of electric machine support 11, housing 1, connects blade 7.Contacting point at motor shaft and inwall 3 is equipped with seal ring 8, and seal ring 8 is used for preventing air through air channel 4 from the slit flow exhaust passage 4 between motor shaft and the inwall 3, thereby enters in the external environment condition.In order to prevent that 8 of seal ring from moving or come off, seal ring fixed support 9 is installed on seal ring 8.Seal ring fixed support 9 is fixed on the inwall 3 after seal ring 8 is compressed again, and seal ring 8 just can not be shifted like this.
Install for convenience, electric machine support 11 can adopt two ends to fixedly connected with angle steel 10 by bolt, and two angle steel 10 are welded on the structure on the inboard of inwall 3 respectively, like this when dismounting, only bolt need be unclamped, just motor 5 and electric machine support 11 can be lifted down together, convenient in the extreme.
Simultaneously, the two ends in the cavity that forms in the middle of the inwall 3 can connect airduct respectively, pass to clean cold wind, can force cooling to the motor 5 in the running, guarantee the normal operation of motor 5.
Between electric machine support 11 and inwall 3, a segment distance is arranged, outside motor shaft is exposed to.In order to prevent that dust enters the motor shaft position in the external environment condition; motor shaft is damaged; influence the normal operation of motor 5; can the pertusate flase floor 6 of mounting strap in the both sides of electric machine support 11; space with electric machine support 11, a sealing of inwall 3 formation; prevent that oarse-grained dust from entering, and protected motor shaft injury-free.
Same, in order not influence flowing of air, the air channel 4 between inwall 3 and the outer wall 2 is preferably reduced and is turned round greatly, tip can be arranged in the two ends up and down of inwall 3, the circulation in increase air channel 4.The outside, the middle part of 4 outer wall 2 is provided with maintenance door B13 in the air channel, also is provided with maintenance door A12 on the outer wall of blade 7 present positions.Simultaneously, can also on outer wall 2, be provided with two maintenance door A12 and maintenance door B13 respectively symmetrically.Just two are maintained door A12 symmetries, two maintenance door B13 symmetries.Be provided with after maintenance door A12, the maintenance door B13,, can clear up, need not to take apart air exhauster by opening the maintenance door when in the air channel 4, when dust or other foreign material deposition are arranged on the blade 7, very convenient.
In use, the two ends of air exhauster of the present utility model are connected by airduct in the equipment or environment that will ventilate, motor 5 rotates, and drives blade 7 and rotates, and circulate the realization degassing function in air channel 4 thereby promote air.Because motor 5 is not arranged in the air channel 4, isolate with working environment, even contain a large amount of moisture content or dust in the air, can not pollute motor 5 yet, thereby protect motor 5, also prolonged the working life of motor 5.Simultaneously, because the air that will get rid of and motor 5 isolation, even hot blast can not cause heating to motor 5 yet.Because motor 5 in use itself can produce certain heat, and motor 5 overheated meetings impact the use of motor 5, and heat insulating function has also improved the service time of motor 5, helps the heat radiation of motor 5.Simultaneously,, can on inwall 3, set up thermal-protective coating,, prevent that motor 5 is overheated such as thermal insulating pads such as silicate aluminum boards in order further to strengthen effect of heat insulation.In addition, in air, contain when using in the environment of flammable explosive gas,, also played explosion-proof function well because motor 5 contacts with workpiece, air etc.In addition, blast regulation range of the present utility model can be from 10Pa to 1500Pa, and is applied widely.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technological scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the present utility model.
