The specific embodiment
By Fig. 1 to 6 as can be known, the utility model is made up of magnetic stirrer 10 and the crucible 9 that is arranged on magnetic stirrer 10 centers, wherein:
Iron core 2 be arranged on uniformly crucible 9 in the housing 1 around, iron core 2 bottoms are provided with yoke 11, iron core 2 upwards is evenly equipped with the teeth groove 13 that forms between core tooth 12 and the core tooth 12, and iron core 2 is fixing by the trim ring 4 that is arranged on top and bottom.
Described coil 3 is arranged on around the crucible 9, and alternate being embedded in iron core 2 teeth groove 13;
Described housing 1 an outside side is provided with water inlet pipe 8, housing 1 an inner side is provided with the tank 5 that communicates with water inlet pipe 8, housing 1 bottom is provided with the circular passage that communicates with tank 5, the circular passage is provided with introduces branch water expanded metals hole 6 in the housing 1 with cooling water, housing 1 top also is provided with the cooling water circular passage, and housing 1 outside opposite side is provided with the outlet pipe 7 that communicates with the upper, annular passage.
Coil 3 described in the utility model comprises winding a, b, c, d, e, f, wherein winding a, d series connection is a phase coil, and winding b, e series connection is a phase coil, and winding c, f series connection is a phase coil, wherein three ends of the same name are linked to be asterism, and three-phase coil leads to the three-phase quadrature current.Described coil 3 adopts three-phase helix tube winding.Described iron core 2 magnetic circuits are set to open circuit.Described housing 1 center is a working face, and housing 1 top is provided with suspension ring.
Operation principle of the present utility model:
The travelling-magnetic-field magnetic stirrer is made of agitator iron core, coil and non-magnetic stainless steel housing.The travelling-magnetic-field magnetic stirrer is the same with linear electric motors, all is the stator differentiation by normal asynchronous.It can be regarded as the stator of an asynchronous motor is radially cut open, with the circumference generate straight line of motor, promptly forms the travelling-magnetic-field magnetic stirrer then.The original like this rotating excitation field along the circumference rotation becomes the travelling-magnetic-field of advancing to a direction.Molten metal then substitutes the secondary of motor, thereby constitutes travelling-magnetic-field magnetic stirrer (being called for short STS).
The difference of travelling-magnetic-field magnetic stirrer and asynchronous motor is as follows:
1, the iron core of travelling-magnetic-field magnetic stirrer disconnects, and magnetic circuit is opened a way; The iron core of asynchronous motor is closed, and magnetic circuit also is closed.
1) because each phase winding of travelling-magnetic-field magnetic stirrer is asymmetric in the position of iron core, even under the situation of applied voltage symmetry, three-phase current is also uneven.For this reason, generally adopt the winding configuration of two-phase, guarantee that the two-phase impedance equates that biphase current is in a basic balance at orthogonal space.Three-phase winding electric magnetic stirrer generally will add auxiliary winding makes current balance type.
2) because the magnetic circuit open circuit except that producing direct wave magnetic field, also is attended by backward-travelling wave magnetic field and impulsive magnetic field.
2, because motlten metal is a continuous conductor, induced-current wherein portion within it is closed voluntarily, and the induced-current of motor can only flow and closure in the short-circuited conducting sleeve at two ends along sliver in the rotor.
As shown in Figure 5, magnetic stirrer is set, when feeding the inductor three-phase alternating current, just produces travelling-magnetic-field at crucible
,, thereby produce induced-current because the effect in this magnetic field produces induced potential in liquation
(following the right-hand rule).This induced-current and local magnetic field interaction produce electromagnetic push in liquation
(following left hand rule).
As shown in Figure 5,, promote liquation and do the convection current campaign, cause the effect of the equalizing temperature of liquation levels because this thrust follows the effect of ripple magnetic direction.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
