Technical Field

The magnetic field generated by the coil is provided with a secondary induction coil made of copper alloy, i.e., the melting channel. The resistance of the melting channel and the copper material in the furnace is very small. When the magnetic lines of force pass through, an induced electromotive force and a strong current are generated to melt the metal.

[0003] However, in the prior art, during the process of using an industrial frequency induction furnace to melt copper alloy, it is necessary to manually stir the copper in the industrial frequency induction furnace to increase the smelting speed. However, the manual stirring method increases the labor intensity of the workers. Some industrial frequency induction furnaces for melting copper also use motors to drive the industrial frequency induction furnaces to dump the molten copper after smelting. However, the reduction in torque output due to long-term use of the motor will affect the dumping of the molten copper.

[0004] Therefore, a copper melting industrial frequency induction furnace is proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a copper melting industrial frequency induction furnace, comprising: an industrial frequency induction furnace body 1, support plates 101 are fixedly connected to both sides of the top of the industrial frequency induction furnace body 1, bearing holes 102 are opened on the sides of the two support plates 101, stirring components 3 are arranged inside the two bearing holes 102, four support blocks 104 are fixedly connected to one side of the industrial frequency induction furnace body 1, and movable grooves 105 are opened on one side of the four support blocks 104, and two support blocks 2 106 are fixedly connected to the other side of the industrial frequency induction furnace body 1, and rotating shafts 107 are fixedly embedded in the two support blocks 2 106, and the surfaces of the two rotating shafts 107 are arranged with dumping components 2.

[0023] Specifically: the bidirectional motor 302 is started by an external controller, so that the output end of the bidirectional motor 302 drives the stirring vertical rod 303 and the stirring horizontal rod 304 to stir in the inner cavity of the power frequency induction furnace body 1. This design does not require manual stirring of copper, which reduces the labor intensity of workers. When the copper is melted and the molten copper needs to be discharged, the cylinder 202 can be started by an external controller, and the two cylinders 202 extend through the two support columns 203 to lift the power frequency induction furnace body 1, so that the power frequency induction furnace body 1 rotates upward around the two rotating shafts 107, and the molten copper in the power frequency induction furnace body 1 is discharged from one side of the power frequency induction furnace body 1. The copper liquid is poured out of the discharge port. This design uses a cylinder instead of a motor to avoid the reduction of the torque output due to long-term use of the motor, which affects the pouring of the copper liquid. The main frequency induction furnace body 1 is a prior art. The main frequency induction furnace body 1 includes an induction coil. When an alternating power supply is passed through the induction coil, an alternating magnetic flux is generated. This magnetic flux interlinks the metal charge in the crucible, thereby causing an induced electromotive force in the charge. Since the conductor of the charge system is a closed loop, a strong induced current is generated under the action of the electromotive force; and due to the surface effect of the current, the strong current only flows along the surface of the charge, generating a large amount of Joule heat, thereby heating the charge and even melting it.

[0024] In one embodiment, a motor plate 103 is fixedly connected to one side of the main body 1 of the industrial frequency induction furnace, and two auxiliary support columns 108 are fixedly connected to the bottom of the main body 1 of the industrial frequency induction furnace.

[0025] Specifically, the two auxiliary support columns 108 are used to provide auxiliary support to the industrial frequency induction furnace body 1 , thereby reducing the weighing burden of the two support columns 203 .

[0026] In one embodiment, the tipping assembly 2 includes a base plate 201, two cylinders 202 are fixedly connected to one side of the top of the base plate 201, two support columns 203 are fixedly embedded inside one end of the two cylinders 202, and four support plates 204 are fixedly connected to the other side of the top of the base plate 201, and bearing holes 205 are opened on the side surfaces of the tops of the four support plates 204.

[0027] Specifically: the cylinder 202 is started by an external controller, and the two cylinders 202 are extended to lift the main body 1 of the power frequency induction furnace through the two support columns 203, so that the main body 1 of the power frequency induction furnace rotates upward around the two rotating shafts 107, and the molten copper in the main body 1 of the power frequency induction furnace is poured out from the discharge port on one side of the main body 1 of the power frequency induction furnace. In this design, the cylinder is used instead of the motor to avoid the reduction of the torque output due to the long-term use of the motor, which affects the pouring of the molten copper.

[0028] In one embodiment, the stirring component 3 includes a rotating shaft 301, one end of which is connected to a bidirectional motor 302, the output end of the bidirectional motor 302 is fixedly embedded in one end of the rotating shaft 301, and three stirring vertical rods 303 are fixedly connected to the bottom of the rotating shaft 301, and multiple stirring horizontal rods 304 are fixedly embedded inside the three stirring vertical rods 303.

[0029] Specifically: the bidirectional motor 302 is started by an external controller, and the output end of the bidirectional motor 302 operates in a manner that the rotation direction will change every time the output end rotates one-third of a circle, so that the output end of the bidirectional motor 302 drives the stirring vertical rod 303 and the stirring horizontal rod 304 to stir the inner cavity of the industrial frequency induction furnace body 1. This design does not require manual stirring of copper and reduces the labor intensity of workers.

[0030] In one embodiment, surfaces at both ends of the two rotating shafts 107 are connected to the inside of the four bearing holes 205 through bearings, and surfaces at both ends of the two supporting columns 203 are movably embedded in the inside of the four movable grooves 105 .

[0031] Specifically: the movable groove 105 provides space for the movement of the support column 203. When the industrial frequency induction furnace body 1 is placed horizontally, the initial position of the support column 203 is located on one side of the movable groove 105. When the output end 202 is lifted, the two ends of the support column 203 follow the lifting and move outward inside the movable groove 105, cooperating to drive the support block 104 to lift, meeting the conditions for the industrial frequency induction furnace body 1 to move in an arc around the rotating shaft 107.

[0032] In one embodiment, the surfaces at both ends of the second rotating shaft 301 are connected to the inside of the two first bearing holes 102 through bearings, and the bottom of the bidirectional motor 302 is fixedly connected to the surface of the motor plate 103 .

[0033] Specifically: the motor plate 103 is used to fix the bidirectional motor 302 to prevent the bidirectional motor 302 from shaking during movement and affecting the normal operation of the device.

[0034] Working principle: This copper melting industrial frequency induction furnace is connected to an external power supply device, and the external power supply device supplies power to the industrial frequency induction furnace body 1, cylinder 202 and bidirectional motor 302. The external controller is electrically connected to the industrial frequency induction furnace body 1, cylinder 202 and bidirectional motor 302. The worker controls the power-on of the industrial frequency induction furnace body 1, the rotation of the cylinder 202 and the elongation of the bidirectional motor 302 through the external controller, puts copper into the inner cavity of the copper melting industrial frequency induction furnace, controls the power-on and heating of the industrial frequency induction furnace body 1 through the external controller, and starts the bidirectional motor 302 through the external controller. The output end of the bidirectional motor 302 operates in a manner that the rotation direction changes every time the output end rotates one-third of a circle. The output end of the bidirectional motor 302 drives the stirring vertical rod 303 and the stirring horizontal rod 304 to stir the inner cavity of the power frequency induction furnace body 1. This design does not require manual stirring of copper, which reduces the labor intensity of workers. When the copper is melted and the molten copper needs to be poured out, the cylinder 202 can be started by an external controller. The two cylinders 202 extend through the two support columns 203 to lift the power frequency induction furnace body 1, so that the power frequency induction furnace body 1 rotates upward around the two rotating shafts 107, and the molten copper in the power frequency induction furnace body 1 is poured out from the discharge port on one side of the power frequency induction furnace body 1. This design uses a cylinder instead of a motor to avoid the dumping of the molten copper due to the reduction of torque output caused by long-term use of the motor.
