The blender comprises a motor stator, a driving motor rotor, and a permanent-magnet pole having both axial ends fixed on the driving motor rotor and the rotating yoke iron of bearing bracket respectively. The utility model is of small volume, simple structure, low cost, reliable operation, and easy control. Additionally, without excitation coil, the utility model basically solves the problem existing in the conventional blender that the coil always in the water causes the insulation damage, so as to mostly prolong the service life and greatly reduce power consumption and cooling water consumption. The utility model is an optimal blender in the metal casting technology field and has great economic benefit and social benefit.
Description
Technical field
The utility model relates to a kind of conticaster agitator, and particularly a kind of conticaster permanent magnetic stirrer belongs to the metal casting technical field.
Background technology
At present, the continuous casting technology of field of metal casting technology all is to adopt traditional magnetic stirrer usually both at home and abroad, the operation principle of this traditional magnetic stirrer is similar to induction machine, by being input to the three-phase low-frequency ac of magnetic pole of the stator coil, form the air-gap field of rotation, under the effect of rotating excitation field, in electric rotors (molten metal liquid), produce electromagnetic torque, metal liquid takes place slowly to flow in the electromagnetic torque effect, realizes that the inside of molten metal is stirred.Because traditional magnetic stirrer adopts the higher low-frequency power of cost, require stir current in the scope of 200-500 ampere according to the difference of billet bloom size, just can reach the stirring purpose, therefore power consumption is big.Because the insulation in water of magnet exciting coil bubble often damages, the coil life-span is short, has increased production cost and working strength of workers again.
The utility model content
The utility model puts forward at the problems referred to above, and purpose provides a kind of consumption that can reduce energy loss and cooling water, and simple in structure, regulation and control convenience, reliable, reduces the conticaster permanent magnetic stirrer of use cost greatly.
To achieve these goals, the technical scheme of the utility model technical solution problem: comprise motor stator, rotor, permanent-magnet pole, the rotation yoke that its axial two ends are individually fixed in rotor and bearing bracket is provided with permanent-magnet pole.
Described motor stator is fixed on the shell.
Described bearing bracket is fixed on the bottom end cover by spring bearing.
Radially locating by backing roll of described rotation yoke by inner slide.
The described permanent magnetism that is fixed on the rotation yoke very is symmetrical arranged.
Described permanent-magnet pole is to be made of several little magnetic patch assembly units, and with corrosion resistant plate Feng Micheng integral body.
The polar arc r of described permanent-magnet pole is best, and radian is 90 ° ± 5 °.
The utility model compared with prior art has following advantage and effect:
Because the inner induction conductivity rotor drive magnetic pole of putting of air-gap field rotation is finished.The magnetic level of band magnet exciting coil replaces with permanent-magnet pole, and the speed of stirring changes control by built-in sensitive motor stator input supply frequency.Be permanent-magnet pole by machine driving form driven rotary, it is little, simple for structure, cheap, reliable to have a volume, regulation and control are convenient.In addition,, thereby realized because magnetic stirrer does not have magnet exciting coil,
1, long service life: fundamentally solved traditional electrical magnetic stirrer coil bubble frequent damage problem of insulation in water.
2, power consumption declines to a great extent: the utility model permanent magnetic stirrer drive motors capacity only is about 5% of a traditional electrical magnetic stirrer capacity, and electric current is exactly the electric current of motor own, so energy consumption reduces, energy-saving effect is very remarkable.
3, cooling water flow reduces: cooling water of the present utility model is than traditional minimizing about 80%, so water-saving result is also very remarkable.

The specific embodiment
Embodiment 1:
Schematic diagram of the present utility model shown in Fig. 1,2 and 3 comprises motor stator 3, rotor 4, permanent-magnet pole 12, and its axial two ends are individually fixed on rotor 4 and the bearing bracket 11; Radially the rotation yoke 13 of being located by backing roll 7 by inner slide 6 is provided with permanent-magnet pole 12.Described permanent-magnet pole 12 is made of several little magnetic patch assembly units, and is that two permanent-magnet poles 12 are positioned at cover 14 outsides on 90 ° of rotation yokes 13 with being symmetricly set on the polar arc angle after the corrosion resistant plate Feng Micheng integral body, and interior cover 14 centres are steel billet 15.Interior cover outer felt is around cooling water pipe 2, motor stator 3 is fixed on the shell 8, motor stator 3 and rotor 4 tops are provided with the fairlead of cooling water pipe 2, described bearing bracket 11 is fixed on the bottom end cover 9 of sealing by spring bearing 10, the outside of shell 8 is provided with outlet box 5, and the top of shell 8 is provided with the upper end cover 1 of sealing.
Embodiment 2:
Described permanent-magnet pole 12 is made of several little magnetic patch assembly units, and be symmetricly set on after the corrosion resistant plate Feng Micheng integral body polar arc angle be 95 ° the rotation yokes 13 on, all the other are with embodiment 1.
Embodiment 3:
Described permanent-magnet pole 12 is made of several little magnetic patch assembly units, and be symmetricly set on after the corrosion resistant plate Feng Micheng integral body polar arc angle be 85 ° the rotation yokes 13 on, all the other are with embodiment 1.
During concrete the use, after the utility model energising, 13 rotations of rotor 4 driven rotary yokes also drive permanent-magnet pole 12 rotations simultaneously.When steel billet 15 liquid flow through the rotating excitation field that is produced by permanent-magnet pole 12 rotation, the liquid metal cutting magnetic line of conduction and induced current, this electric current and magnetic field interaction have just produced electromagnetic force, and steel billet liquid is rotated, thereby realize the effect of stirring.
