Abstract
The utility model discloses an automatic-stirring smelting furnace. The automatic-stirring smelting furnace comprises a furnace body, wherein a feeding inlet and a discharging outlet are arranged on the furnace body; the bottom part of the furnace body is provided with a permanent magnet stirrer; the permanent magnet stirrer is mounted on the bottom part of a smelting furnace; and the stirring operation is performed by the permanent magnet stirring technology. Compared with manual stirring, the automatic-stirring smelting furnace has the following advantages: 1, the operation is carried out without opening a furnace door, the heat consumption is reduced, and 20% of energy consumption can be saved; 2, since components are even and grains are refined, the best smelting effect is achieved; 3, non-direct-contact stirring is adopted so as to avoid artificial secondary pollution, and the generation of aluminum oxide slags is reduced; 4, the smelting speed of the smelting furnace is increased; 5, the temperature difference between the surface layer and the bottom part of a smelting body normally can be controlled within 5 DEG C so as to avoid the smelting body being overheated or being over-burnt locally; and 6, the operation is simple and the labour intensity of workers is reduced greatly.
Description
Technical field
The utility model relates to a kind of smelting furnace, relates in particular to a kind of automatic stirring-type smelting furnace that is used for smelting aluminium alloy.
Background technology
Melting is one of casting production process.Metal material and other auxiliary material are dropped into smelting furnace fusing and modified, make it meet the pouring cast part requirement.The smelting furnace that uses in the market, it does not possess self-poking arrangement, almost all adopts the manual stirring mode, and many drawbacks that manual stirring is brought are badly in need of solving:
1, stirring is inhomogeneous, influences the melting effect, and causes localized burn easily;
2, destroy melt coverture protective layer, increase the aluminium oxide slag;
3, necessary blow-on door operation, a large amount of thermal loss cause specific energy consumption high;
4, manual work, not only labour intensity is big, and is prone to cause secondary pollution.
The utility model content
The purpose of the utility model is to provide a kind of automatic stirring-type smelting furnace, adopts the manual stirring mode to solve traditional smelting furnace, and energy consumption is high, and labour intensity is big, and stirs inhomogeneously, and manual work is prone to cause secondary pollution problem.
The purpose of the utility model is to realize through following technical scheme:
A kind of automatic stirring-type smelting furnace comprises body of heater, and said body of heater is provided with charging aperture and discharging opening, and its bottom is provided with permanent magnetic stirrer.
Further, said permanent magnetic stirrer comprises the permanent magnet inductor, and said permanent magnet inductor cover is fixed on the turning cylinder of motor, and it is for to press circumferencial direction even numbered blocks permanent magnet spaced apart, and the polarity of adjacent permanent magnet is opposite.
Further, said motor is a variable-frequency motor.
Further, the quantity of said permanent magnet is 2,4,6 or 8.
Further, said permanent magnet is a Nd-Fe-B permanent magnet.
The beneficial effect of the utility model does, said automatic stirring-type smelting furnace adopts the permanent magnetism stirring technique to stir through in the smelting furnace bottom permanent magnetic stirrer being installed, and it is compared with manual stirring, has the advantage of following several respects:
1, without the blow-on door operation, reduce thermal losses, can practice thrift 20% energy consumption;
2, uniform ingredients, crystal grain thinning makes the melting effect reach best;
3, non-direct contact type stirs, and avoiding the people is secondary pollution, has reduced the generation of aluminium oxide slag;
4, improved the burn-off rate of smelting furnace;
5, the melt top layer and the bottom temperature difference generally can be controlled in 5 ℃, thereby can avoid the generation of melt hot-spot and burn-off phenomenon;
6, simple to operate, greatly reduce working strength of workers.
Description of drawings
Fig. 1 is the structural representation of the automatic stirring-type smelting furnace of the utility model.
Among the figure:
1, body of heater; 2, permanent magnetic stirrer.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment.
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the automatic stirring-type smelting furnace of the utility model; In present embodiment, a kind of automatic stirring-type smelting furnace comprises body of heater 1; Said body of heater 1 is provided with charging aperture and discharging opening, and is provided with permanent magnetic stirrer 2 bottom it, and said permanent magnetic stirrer 2 comprises the permanent magnet inductor; Said permanent magnet inductor cover is fixed on the turning cylinder of variable-frequency motor; It is for to press circumferencial direction 6 permanent magnets spaced apart, and said permanent magnet is a Nd-Fe-B permanent magnet, and the polarity of adjacent permanent magnet is opposite.
During work, the magnetic line of force in the magnetic field that the permanent magnet inductor produces, from the N utmost point, pass the liquation in the body of heater 1 after; Turn back to the S utmost point, because in the permanent magnet inductor socket rotating shaft, rotating shaft is by the variable-frequency motor driven rotary; Therefore the also synchronous rotation of permanent magnet inductor forms rotating excitation field, and the liquation in this rotating excitation field and the body of heater interacts; Produce induced electromotive force and induced-current, induced-current acts on rotating excitation field again, produces electromagnetic force; Liquation directed flow in this electromagnetic force promotion body of heater 1 makes that the liquation in the body of heater 1 produces rotation and seethes the purpose that realization is stirred.Through to motor variable-frequency speed-regulating, can obtain the rotating excitation field of different frequency, and change the rotation direction of motor; The direction of rotation of body of heater 1 inner melt also changes thereupon, if make the motor positive and inverse alternate run, and can be better to liquation rotation and the mixing effect that seethes; Not only eliminate the stirring dead angle, prevented component segregation, guaranteed the uniformity of alloying component; And effectively reduced the temperature difference of smelting furnace internal upper part and bottom, accelerated the burn-off rate of non-ferrous metal, in addition; Contactless stirring has been avoided because the secondary pollution that manual work causes.
Above embodiment has just set forth the basic principle and the characteristic of the utility model; The utility model is not limited by the foregoing description; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various variations and change, and these variations and change all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
