Abstract
A magnetic driving fan of an autoclave comprises fan blades, an inner magnet fixed on a rotating shaft of the fan blades, a motor and an outer magnet fixed on a rotating shaft of the motor. The motor is arranged outside a back housing of the autoclave, the fan blades are arranged in the back housing of the autoclave, and the inner magnet and the outer magnet are correspondingly arranged by being separated by the autoclave. The N pole of the inner magnet corresponds to the S pole of the outer magnet, the S pole of the inner magnet corresponds to the N pole of the outer magnet, and magnetic acting force is reserved between the inner magnet and the outer magnet. Both the inner magnet and the outer magnet are of arc strip-shaped structures and are fixed on the rotating shaft through plastic parts wrapped outside the magnets, the arc surface at the back end of the inner magnet is parallel to the inner arc surface of the back housing, and the arc surface at the front end of the outer magnet is parallel to the outer arc surface of the back housing. When the motor drives the outer magnet to rotate, a rotating magnetic field is generated, the inner magnet drives the fan blades to rotate under the magnetic effect of the outer magnet, therefore interior heat convection of the autoclave is improved, and transparency and uniformity of laminated glass are improved.
Description
Technical field
The utility model relates to the autoclave of making laminated glass-use, relates to specifically the magneto drive fan of autoclave.
Background technique
The special-purpose autoclave of existing glass manufacture, all heating pipe to be installed in still inner bottom part, the left and right sides treat processed glass and heat, certainly will exist like this position close to the heating pipe be heated higher, away from the position of the heating pipe not enough phenomenon of being heated, cause the laminated glass heating uneven, heat near the glass of thermal source too high, the film liquefaction between glass sandwich is run off; The glass of stow away from heat is heated not, and the film between glass sandwich does not reach molten state, affects the quality of glass, comprises transparency, bubble, adhesion strength etc.
201020614769.X " a kind of forced convection glass autoclave " patent document discloses in the central technological scheme that induced draft fan is installed of steam pressure kettle seal closure (being equal to rear casing of the present invention), 11(at Figure of description 2 marks does not have reference character, we are interpreted as motor) link together by rotating shaft and blade 12, this scheme can effectively be improved the technical problem that is heated evenly really, but existing the rotation axis seal problem does not solve, it is high-temperature high-pressure state in glass autoclave, temperature is 130 degrees centigrade, pressure is 12 kilograms of left and right, at least got continuous operation 4 – 6 hours, under such operating mode, soft sealing material is easy to lose efficacy, cause frequently changing the trouble of seal arrangement.Require higher manufacturing aeronautical material autoclave for pressure, internal pressure is up to 30 kilograms, and the shaft sealing technology is difficult to because pressure is too high realize more.
If the fan of translator is set in autoclave inside, because motor is not suitable for working under high temperature, high pressure, at present temporarily without this possibility.
In view of this, the inventor furthers investigate, and designs a kind of magneto drive fan of autoclave of novelty, and a kind of Non-connecting power is provided, and this case produces thus.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, the not electromagnetic force drive fan of direct coupled autoclave of a kind of fan and machine shaft is provided, the rear casing of autoclave is complete not perforate, has solved up hill and dale the sealing problem at the high temperature and high pressure condition lower rotary shaft.
The present invention is achieved by following technical proposals:
The magneto drive fan of autoclave comprises: fan blade, be fixed on inner magnet, the motor in the fan blade rotating shaft and be fixed on outer magnet on machine shaft; Rear casing central authorities are provided with an axle with the level in the autoclave enclosure interior, and the rotating shaft of fan blade is connected on Step Shaft by bearing and snap ring;
Described motor is arranged on outside the autoclave rear casing, it is inner that described fan blade is arranged on the autoclave rear casing, described inner magnet and outer magnet are across the corresponding installation of autoclave rear casing, the N of inner magnet extremely corresponding the S utmost point of outer magnet, the S of inner magnet extremely corresponding the N utmost point of outer magnet, inner magnet and the outer magnet active force that is magnetic each other.
Inner magnet and outer magnet are all the list structures of circular arc, the working of plastics of all by the magnet coated outside is fixed in rotating shaft, its arc surface of inner magnet rear end that is fixed in the fan blade rotating shaft is parallel with the rear casing intrados, its arc surface of outer magnet front end that is fixed on machine shaft is parallel with the rear casing outer arced surface, inner magnet and outer magnet are all apart from autoclave rear casing 1-10mm, in the situation that guarantee not swipe, as far as possible close, to obtain maximum magnetic attraction.
When the motor drives outer magnet rotates, produce a rotating magnetic field, inner magnet just drives the fan blade rotation under the magnetic force of outer magnet, improve the convection current of autoclave internal heat, improves transparency and the uniformity of laminated glass, improves the quality of products.
The beneficial effects of the utility model are: owing between fan blade and motor being Non-connecting transmission by the magnet transferring power, the rotating shaft that does not need to arrange by the autoclave rear casing comes direct-drive, there is not the sealing problem of rotating shaft, make and make pressure and become possibility greater than 30 kilograms and autoclave with fan, avoided the trouble of frequent replacing seal arrangement and saved cost, under the prerequisite of effectively improving the quality of products, also improved output; Simple in structure, maintenance easily.

Fig. 2 is the cutaway view Amplified image at autoclave rear casing position.
Description of reference numerals:
1 autoclave housing, 2 rear casings, the 2-1 Step Shaft, 3 fan blade, 4 inner magnets, the 4-1 inner magnet is moulded shell, 5 outer magnets, the 5-1 outer magnet is moulded shell, 6 motors.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
Embodiment 1
The structure of the electromagnetic force drive fan of autoclave comprises as shown in Figure 1: autoclave housing 1, rear casing 2, fan blade 3, inner magnet 4, outer magnet 5, motor 6.
The front end of autoclave housing 1 is door, the rear end is rear casing 2, rear casing 2 central authorities are provided with an axle in autoclave housing 1 inside, be provided with 2 bearings on axle, the rotating shaft of fan blade 3 just is fixed on these 2 bearings, being fixed on the inner magnet 4 in fan blade 3 rotating shafts and the outer magnet 5 that is fixed in motor 6 rotating shafts is all the list structure of circular arc, and the shell of moulding of all by the magnet coated outside is fixed in rotating shaft; Motor 6 is arranged on autoclave rear casing 2 outsides, and fan blade 3 is arranged on autoclave housing 1 inside, and inner magnet 4 and outer magnet 5 are all apart from autoclave rear casing 1-10mm.The rotating shaft that does not have transmitting torque on autoclave rear casing 2 is passed through, inner magnet 4 and outer magnet 5 are across the corresponding installation of autoclave rear casing 2, the N of inner magnet 4 extremely corresponding the S utmost point of outer magnet 5, the S of inner magnet 4 extremely corresponding the N utmost point of outer magnet 5, active force each other is magnetic.
When motor 6 drives outer magnet 5 rotation, produce a rotating magnetic field, inner magnet 4 just drives fan blade 3 rotations under the magnetic force of outer magnet 5, improves the even problem of autoclave internal heat convection current, improve transparency and the uniformity of laminated glass, improve the quality of products.
