Description
Technical field permanent-magnet type mixer of the present invention relates to a kind of mixing plant of molten metal bath.
The mixing plant that background technology is used for molten metal bath at present has magnetic stirrer, and electromagnetic agitation is that noncontact is stirred, and pollution-free to melt in the whipping process, through electromagnetic agitation, alloying component is even, the melt temperature equilibrium, and iron loss is few, saves the energy.Therefore in melting and casting cycle, magnetic stirrer is used widely.Magnetic stirrer has revolving-field type, travelling-magnetic-field type and helical magnetic field type.Magnetic stirrer electricity consumption miscarriage magnetisation field will consume a large amount of electric energy, for reducing the power consumption of magnetic stirrer, proposes permanent-magnet type mixer.
The purpose of summary of the invention permanent-magnet type mixer of the present invention is to propose a kind of energy-saving agitator that replaces electromagnetic field with the magnetic field of permanent magnet, it is by the magnetic roller, fixed frame and transmission mechanism three parts are formed, the magnetic roller is made up of pipe yoke and strong permanent magnetic body, fixed frame partly comprises the chassis, bearing, carriage, the stainless steel water sleeve, running part comprises motor, gearbox, driving wheel, synchronizing wheel, be with synchronously and axle, it is characterized in that: permanent magnet is arranged on the outer wall of pipe yoke, and arrange along the bus of pipe yoke, just formed travelling-magnetic-field magnetic roller, carriage, motor, gearbox is fixed on the chassis, the stainless steel water jacket is fixed on the carriage, and axle is established at pipe yoke two ends, pipe yoke and the coaxial placement of water jacket, the axle of yoke is arranged on the bearing, synchronizing wheel is set on axle, and synchronizing wheel links to each other with being with synchronously with the driving wheel of gearbox, and motor links to each other with gearbox.Many magnetic rollers are set in parallel on the chassis, and link to each other synchronously with synchronizing wheel by synchronous band, have just formed travelling-magnetic-field type permanent magnetic stirrer.
Motor adopts the variable-frequency power sources power supply.After connecting power supply, motor rotates, and by gearbox, the trend driving wheel rotates, and drives each pipe yoke by synchronous band synchronizing wheel and rotates, and the permanent magnet on the pipe yoke is made circular motion, has formed travelling-magnetic-field in the space.
In like manner, when permanent magnet is arranged on the inwall of pipe yoke, along the arrangement of embarking on journey of pipe yoke bus, the magnetic line of force direction of adjacent two row magnets is opposite, just formed rotating excitation field magnetic roller, when the magnetic roller rotated, then permanent magnet formed rotating excitation field in the inner space of pipe yoke.When permanent magnet is arranged on the outer wall of pipe yoke, and arrange along the lip-deep helix of pipe, just form helical magnetic field magnetic roller, when the magnetic roller rotated, then permanent magnet was at the space outerpace formation helical magnetic field of pipe yoke.

The specific embodiment
Embodiment 1 travelling-magnetic-field type permanent-magnet type mixer
Its structure as depicted in figs. 1 and 2, permanent magnet 13 is arranged on the outer wall of pipe yoke 14, and arranges along the bus of pipe yoke, has then formed travelling-magnetic-field magnetic roller, carriage 11, motor 6, gearbox 7 are fixed on the chassis 1, stainless steel water jacket 12 is fixed on the carriage, and axle 4, pipe yoke and the coaxial placement of water jacket are established in pipe yoke two ends, the axle of yoke is arranged on the bearing 3, synchronizing wheel 9 is set on axle, and synchronizing wheel is with 9 to link to each other with driving wheel 8 usefulness of gearbox synchronously, and motor links to each other with gearbox.Many magnetic rollers are set in parallel on the chassis, and link to each other synchronously with synchronizing wheel by synchronous band, have just formed travelling-magnetic-field type permanent magnetic stirrer.
Motor links to each other with variable-frequency power sources by power line.When power supply is powered, motor rotates, ordering about driving wheel by gearbox rotates, driving the pipe yoke by synchronous band and synchronizing wheel rotates, the permanent magnet that is arranged on pipe yoke outer wall is made circular motion, permanent magnet forms travelling-magnetic-field at the space outerpace of pipe yoke, has recirculated cooling water to flow through in the water jacket, makes permanent magnet be in low temperature environment.
Embodiment 2 revolving-field type permanent-magnet type mixers
Its structure as shown in Figure 3, permanent magnet is fixed on the inwall of pipe yoke, and along the arrangement of embarking on journey of pipe yoke bus, the magnetic line of force direction of adjacent two row magnets is opposite, just formed rotating excitation field magnetic roller, gear ring 17 is fixed on the outer wall of pipe yoke, and coaxial with the pipe yoke, is provided with circular hole on the chassis, the aperture is identical with the water jacket external diameter, water jacket is fixed in the circular hole on chassis, and water jacket is vertical with the chassis.Driving gear and gear ring intermesh, and registration roller and pinion yoke define the pipe yoke position.Motor links to each other with gearbox, and gearbox links to each other with driving gear, and motor is powered by variable-frequency power sources.
