Fig. 1 is the design sketch that melt in the stove melting container washes away container that waves that generally uses at present.
Fig. 2 is the structural representation of the utility model.
Embodiment
The structure of the utility model is as shown in Figure 2.Whole vacuum melting furnace adopts symmetric design, makes the vacuum melting furnace rotating element be in equilibrium state, reduces body of heater 1 impact to drive disk assembly in rotation process, prolongs the work-ing life of stove.Body of heater 1 adopts the wire spiral heating, and the wire spiral outlet line connects brush ring 2, and brush 3 connects the output of heating control instruments.The thermopair outlet line connects brush ring 6, and brush 7 connects the temperature signal input of control instruments.Brush ring 2,6 adopts copper to do, and is fixed on the rotation axis 5, adopts resistant to elevated temperatures teflon insulation between brush ring 2,6 and the rotation axis 5, and brush 3,7 adopts the copper and the graphite sintering brush of self-lubricating.Each brush ring 2,6 is joined 3,7 employings of 3,7, three brushes of three brushes and is connected in parallel, and can effectively prevent the phenomenon of body of heater 1 in the loose contact of rotation process center brush.The electric motor driving assembly adopts alternating current machine, worm reducer and chain drive, and alternating current machine adopts frequency converter timing, can change the rotational frequency of body of heater very on a large scale.Worm reducer is connected with alternating current machine; Slow down the back through 1 rotation of chain drive body of heater; Adopt the benefit of worm reducer to be that worm reducer has latch functions, when alternating current machine did not rotate, body of heater 1 promptly was fixed; The situation that body of heater 1 drives the alternating current machine rotation can not occur, can body of heater 1 be stopped at any angle.Adopt chain drive can overcome the shortcoming that belt transmission is skidded, and have, flexibly advantage more easy for installation than geartransmission.Body of heater 1 leans on stationkeeping one PM of support 4; Support 4 corresponding stationkeeping one Hall elements; Hall element connects velocity gauge, and body of heater 1 whenever circles, and signal of Hall element output is given velocity gauge; Through velocity gauge multiple signal is calculated the rotating speed that the back shows body of heater, like this can be easily, the velocity of rotation that gets information about and regulate body of heater.
2,3 pairs of body of heater hot spotss of brush assembly of electric provide power supply; Brush assembly of electric 6,7 is exported the temperature output signal of temperature thermocouples simultaneously; In order to prevent that the brush loose contact from causing heating power supply and temperature signal fluctuation; Brush adopts the multiple contact brush designs, when turning to any position, always has a brush and brush ring to be in reliable contact condition to reach body of heater.
Body of heater 1 is made up of shell, rotation axis 5, heating unit; Body of heater 1 adopts symmetric design to keep the balance of body of heater in rotation process; Reduce vibrations; The body of heater moving axis 5 that can rotate is done 360 degree rotations, and its rotational frequency and turning direction are controlled by the electric motor driving assembly, and the body of heater heating unit can be multiple type of heating such as resistance heater, intermediate frequency heater.The electric motor driving assembly comprises motor and drive disk assembly, and drive disk assembly can be geartransmission, belt transmission, chain drive.Brush assembly of electric 2,3,6,7 is used for the brush assembly of electric 2,3 of hot spots and is used to export the brush assembly of electric 6,7 of temperature thermocouple temperature output signal.Brush assembly of electric 2,3,6,7 is a donut, and brush assembly of electric 2,3,6,7 is fixed on the body of heater rotation axis 5, brush ring 3,7 and rotation axis 5 insulation and concentric, and in order to prevent the brush loose contact, brush adopts the designs of getting an electric shock more.
