Description

TECHNICAL FIELD

[0001] The utility model relates to induction furnace technical field, concretely is a kind of energy-saving intelligent induction furnace. BACKGROUND

[0002] Induction furnace, also known as induction heating furnace, is a kind of equipment using electromagnetic induction principle to heat and smelt metal materials, and its working principle is based on Faraday's law of electromagnetic induction. When the changing magnetic field passes through the conductor, eddy current is induced in the conductor. Because the resistance of metal materials resists the flow of current, these eddy currents generate heat inside the metal materials, achieving the heating and smelting of metal materials. The existing induction heating furnace is mainly composed of furnace body and heating coil. The furnace body is rotatably connected to the inside of the frame, and the rear end of the furnace body is connected to a steel cable. During use, the metal material is put into the furnace body, and then the heating coil is energized to act on the metal material. The resistance of the metal material in the furnace resists the flow of current, generating a large amount of heat, which smelts the block-shaped metal material into liquid state. Then the winch works, the steel cable tightens upwards, driving the lower end of the furnace body to deflect upwards, and the high-temperature liquid metal flows out from the pouring gate, facilitating subsequent pouring work. During the process of traditional induction heating furnace, a large amount of heat is generated when the block-shaped metal changes into liquid metal. These heat directly escapes into the air through the open furnace mouth above, causing waste of heat. The flexible steel cable cannot accurately control the precision of the furnace body tilting, which is not convenient for subsequent pouring work. Therefore, an energy-saving intelligent induction furnace is proposed. SUMMARY

[0027] The working principle of the energy-saving intelligent induction furnace provided by this utility model is as follows: When using the energy-saving intelligent induction furnace to heat and melt metal, the feeding process is carried out first. At this time, the deflector frame 41 is in an upward deflection state, the furnace opening of the furnace body 2 is open, and the block metal is put into the furnace body 2. The microcontroller 9 controls the second motor 454 to run. The output shaft of the second motor 454 drives the worm gear 455 to rotate, and the worm wheel 456 also rotates accordingly, driving the deflector frame 41 to deflect downward until the outer edge of the coil 44 enters the recess 6. At this time, the coil 44 blocks the furnace opening of the furnace body 2, and then the heating and melting process begins. The microcontroller 9 controls the induction coil 7 and temperature sensor 8 to work. When the induction coil 7 is energized, it acts on the metal block. The resistance of the metal block inside the furnace body 2 resists the flow of current, generating a large amount of heat. The high temperature melts the metal block into a liquid state. Simultaneously, the microcontroller 9 controls the operation of motor 453. The output shaft of motor 453 drives gear 452 to rotate, and gear 451 also rotates accordingly. Because a frame 43 is provided between the opposing inner surfaces of the two rotary joints 42, the rotating ends of the two rotary joints 42 provide a foundation for the rotation of the frame 43 and the coil 44. Furthermore, because... Gear 451 meshes with gear 452, so when gear 451 rotates, gear 452 also rotates, driving frame 43 and coil 44 to rotate. The rotating coil 44 continuously passes over the furnace opening of furnace body 2, absorbing the heat emitted from the furnace opening and heating the water flow inside the coil 44. Temperature sensor 8 monitors the internal temperature of furnace body 2 in real time and sends an electrical signal to microcontroller 9. When the internal temperature of furnace body 2 is low, microcontroller 9 controls motor 453 to rotate slowly; when the internal temperature of furnace body 2 is high, microcontroller 9 controls motor 453 to rotate quickly, allowing for flexible heating of the heating plate. The water flow inside pipe 44 wastes surface heat. When the liquid metal inside furnace body 2 reaches a suitable temperature, it needs to be tilted. Motor 2 454 rotates and drives the deflector frame 41 to deflect upward to provide clearance for furnace body 2. Microcontroller 9 controls motor 3 53 to operate. The output shaft of motor 3 53 drives connecting rod 2 52 to deflect upward. At this time, since the length of connecting rod 1 51 is fixed, as connecting rod 2 52 rotates, connecting rod 1 51 moves to the left and deflects upward at the same time, causing the lower end of furnace body 2 to deflect to the upper left. Furnace body 2 tilts, and liquid metal can flow out from the gate 3.

[0028] It is worth noting that the microcontroller 9 disclosed in the above embodiments is an ATMEGA2560-16AU microcontroller, motor 1 453 is a VGF42 motor, motor 2 454 is an EY410 motor, motor 3 53 is a YE4 motor, and temperature sensor 8 is a WZPK2233 temperature sensor. The microcontroller 9 controls the operation of motor 1 453, motor 2 454, motor 3 53 and temperature sensor 8 using methods commonly used in the prior art.
