The utility model relates to an electromagnetic stirrer, and belongs to the technical field of stirring devices. The electromagnetic stirrer comprises a motor. The motor is fixed to a motor support and connected with a rotating shaft through a chain, the bottom end of the rotating shaft is arranged on a base, a phase changer is fixed to the rotating shaft, and an electric brush is installed at the corresponding position of the phase changer, fixed to a base support and externally connected with a power source. A rotating shaft assembly matched with the rotating shaft is fixed above the base support, a yoke is arranged above the rotating shaft assembly and fixedly connected with the rotating shaft, a permanent magnet is fixed to the yoke, and coils wind around the permanent magnet and are connected with the phase changer. According to the electromagnetic stirrer, the way that the coils wind around the permanent magnet is adopted, the intensity of a total magnetic field is greatly improved, and stirring is uniform and full when the electromagnetic stirrer is adopted for stirring of large melting furnaces.
Description
Technical field
The utility model relates to a kind of melting furnace agitating device, is specifically related to a kind of furnace bottom electromagnetic mixing apparatus.
Background technology
In recent years, the aluminium industrial development of China is rapid, and the quality of aluminium product constantly promotes, and continuing to bring out of large capacity aluminium smelting furnace, has higher requirement to product quality.Traditional artificial and mechanical agitation solution methods, wastes time and energy, and is difficult to stir, and affects product quality, has been difficult to meet production requirement.Electromagnetic agitating technology has obtained development fast to stir conveniently, fully, not pollute the advantages such as aluminum melt, and the electromagnetic agitation modes that adopt comprise more at present: permanent magnetic stirring, AC excitation stirring etc.Best permanent magnet is neodymium iron boron material at present, general multiplex on small boiler, and its magnetic field intensity is still difficult to meet compared with the application of melting pot.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of magnetic stirrer is provided, increases magnetic field intensity, make it can be applied to larger furnace equipment.
Magnetic stirrer described in the utility model, comprise motor, motor is fixed on electric machine support, motor is by chain connection of rotating axle, turning cylinder bottom is arranged on base, fixing phase changer on turning cylinder, phase changer opposite position is installed brush, and brush is fixed on base support, and brush connects external power supply, the fixing turning cylinder assembly coordinating with turning cylinder in base support top, turning cylinder assembly top arranges yoke, and yoke is fixedly connected with turning cylinder, fixed permanent magnet on yoke, permanent magnet outer felt coiling, coil is connected with commutator.
By brush and phase changer, making the current conversion of external power supply is the constant current in coil, makes coil produce the magnetic field identical with permanent magnet magnetic field direction, greatly strengthens total magnetic intensity.Turning cylinder assembly comprises bearing and bearing block, and turning cylinder is played the role of positioning, and permanent magnet and coil can be many groups, can evenly be fixed on yoke by screw.
The bearing and the bearing block that coordinate with turning cylinder are installed on described base.Base coordinates with turning cylinder assembly, turning cylinder is played a supportive role, and prevent the bad phenomenon such as turning cylinder generation beat.
During the utility model application, the furnace bottom that is arranged on melting furnace, switches on power, and motor rotates by chain-driving turning cylinder, turning cylinder drives permanent magnet and the coil on yoke to pivot, the magnetic field that permanent magnet and coil produce is rotation thereupon also, in melting furnace solution in rotating excitation field, the magnetic line of force of cutting magnetic field, produce induced-current, the Yu Yuan stationary magnetic field, magnetic field that induced-current produces interacts and forms magnetic moment of torsion, and magnetic moment of torsion drives solution rotating, reaches contactless well-beaten object.
The beneficial effect that the utility model compared with prior art had is:
The utility model adopts the mode of permanent magnet outer felt coiling, has greatly strengthened total magnetic intensity, while making stirring that it is applied to larger melting furnace, stirs, fully, and base coordinates with turning cylinder assembly, prevents the bad phenomenon such as turning cylinder generation beat.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation
In figure: 1, electric machine support; 2, motor; 3, seal bootr; 4, coil; 5, permanent magnet; 6, yoke; 7, turning cylinder assembly; 8, base support; 9, brush; 10, turning cylinder; 11, base; 12, phase changer; 13, chain.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the present embodiment comprises motor 2, motor 2 is fixed on electric machine support 1, motor 2 drives turning cylinder 10 to rotate by chain 13, chain 13 is connected on the gear of turning cylinder 10, turning cylinder 10 one end are fixed on base 11, turning cylinder 10 gear tops are phase changer 12 fixedly, phase changer 12 opposite positions are provided with brush 9, brush 9 is fixed on base support 8, brush 9 connects external power supply, base support 8 top fixed bias circuit assemblies 7 coordinate with turning cylinder 10, turning cylinder assembly 7 comprises bearing, the parts such as bearing block, turning cylinder assembly 7 tops are yoke 6 fixedly, on yoke 6, be screwed two groups of permanent magnets 5, permanent magnet 5 outer felt coilings 4, coil 4 is connected with commutator 12.
The bearing and the bearing block that coordinate with turning cylinder 10 are installed on base 11.Base 11 coordinates with turning cylinder assembly 7, turning cylinder 10 is played a supportive role, and prevent that turning cylinder 10 from the bad phenomenon such as beat occurring.
During the present embodiment application, be arranged on the furnace bottom of melting furnace, connect motor 2 power supplys and external power supply, motor 2 drives turning cylinder 10 to rotate by chain 13, turning cylinder 10 drives permanent magnet 5 and coil 4 on yoke 6 to pivot, coil 4 produces the magnetic field consistent with permanent magnet 5 directions by phase changer 12 with brush 9 access electric currents, thereby greatly strengthened the original magnetic field intensity of permanent magnet 5, in melting furnace, solution is in rotating excitation field, the magnetic line of force of cutting magnetic field, produce induced-current, the Yu Yuan stationary magnetic field, magnetic field that induced-current produces interacts and forms magnetic moment of torsion, magnetic moment of torsion drives solution rotating, reach contactless well-beaten object.
The utility model adopts the mode of permanent magnet outer felt coiling, has greatly strengthened total magnetic intensity, while making stirring that it is applied to larger melting furnace, stirs, fully, and base coordinates with turning cylinder assembly, prevents the bad phenomenon such as turning cylinder generation beat.
