The utility model comprises a shell, an electrical motor and a permanent-magnet and is characterized in that: the permanent magnet generating field adopts a pair of positive and the negative magnetic poles, which are equipped in a magnetic conductive hollow shaft of a driven electrical motor rotor; a non-magnetic steel internal sleeve is provided between the positive and the negative magnetic poles and is provided with a certain aperture; the driven electrical motor rotor is provided with a stainless steel shell on the outer side; the connection part of the upper and the lower sealing end covers adopts sealing structure. The utility model has the advantages of cooling water operation of sealing equipment, reliable operation and long service life and is an ideal upgrade product of electromagnetic blender.
Description
Technical field the utility model relates to the permanent magnetic stirrer that uses in a kind of metallurgical continuous casting technology.
The magnetic stirrer that adopts in the at present domestic and international metallurgical continuous casting technology of background technology mainly is an electromagnetic induction type.Because they adopt the higher low-frequency power of cost, and the exciting current of magnetic stirrer is big, the usage factor of energy is extremely low, complex structure, the production cost height is again because magnet exciting coil moves in water, insulaion resistance is subjected to water quality impact, service life is short, increased the workload of maintenance, maintenance, limited the application of induction type magnetic stirrer.
The summary of the invention the purpose of this utility model is to overcome the shortcoming of prior art, and a kind of 3 phase 380V that can directly adopt factory are provided, and the power supply power supply of 50HZ is simple in structure, reliable, in light weight, the permanent-magnet type mixer of being convenient to keep in repair.
The utility model is to realize like this, it is made up of housing, motor, permanent magnet etc., it is characterized in that the described permanent magnet that can produce magnetic field adopts a pair of positive and negative magnetic pole, and it is installed in the hollow shaft of magnetic conduction of drive motors rotor, be set in the nonmagnetic steel between the positive and negative magnetic pole, cover leaves certain aperture in the nonmagnetic steel, is provided with the stainless steel casing in the outside of drive motors stator, adopts hermetically-sealed construction with the junction of upper and lower two end covers.
Appended drawings 1 is a structural representation of the present utility model.
Accompanying drawing 2 be the utility model Fig. 1 generalized section.
The specific embodiment is described further the utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing 1,2, the utility model is made up of housing, motor, permanent magnet etc., it is characterized in that the described permanent magnet that can produce magnetic field adopts a pair of positive and negative magnetic pole 1, and it is installed in the hollow shaft 5 of magnetic conduction of drive motors rotor 2, cover 8 is located between the positive and negative magnetic pole in the nonmagnetic steel, cover 8 leaves certain aperture in the nonmagnetic steel, so that the copper pipe and the water conservancy diversion water jacket of crystallizer are installed.The hollow shaft 5 of a pair of positive and negative magnetic pole 1 and magnetic conduction has been formed closed magnetic field.When the steel flow of liquid state is crossed rotating excitation field, the liquid metal cutting magnetic line of conduction and induced current, this electric current and magnetic field interaction have just produced electromagnetic force, liquid molten steel are rotated, to reach the purpose of stirring.Thereby improved the solidified structure of metal, improved the quality of continuous casting billet.
Because this agitator is to be placed in the cooling water to move, so hermetically-sealed construction is adopted in the junction of the utility model cover 8 in the outside of drive motors stator 3 is provided with stainless steel casing 4 and upper and lower two end covers 7 and nonmagnetic steel.Cover 8 and housing 4 seal permanent-magnet type mixer fully in upper and lower two end covers 7, nonmagnetic steel, motor down-lead also adopts soft seal pipe 6, motor and permanent magnet are isolated with water, can not only guarantee agitator safe and reliable operation in cooling water, and can also prolong its service life.
The utility model has the advantages that does not have magnet exciting coil owing to adopted said structure in the agitator, do not need jumbo low frequency power supply equipment, and motor can adopt special low speed asynchronous machine, also can adopt the motor of other kind such as synchronous motor.Power supply can directly adopt 3 phase 380V of factory, and expensive low-frequency power has been saved in the power supply power supply of 50HZ, has reduced cost effectively; Owing to this equipment is to seal to be installed in the cooling water to move, the insulation of motor is not subjected to the influence of water quality in addition, thus reliable, long service life.It is the desirable renewal product of magnetic stirrer.
The utility model agitator can be directly installed in the housing of crystallizer, utilizes the water quench of crystallizer; If when being placed on two cold-zones or end, cover in the shell of permanent magnetic stirrer and the nonmagnetic steel also must add one deck sealing cooling jacket, independent water flowing cooling, and strand passes through the cooling jacket endoporus.
