Description

Technical Field

[0001] This utility model relates to the technical field of metal smelting, specifically to a medium-frequency induction melting furnace that facilitates unloading. Background Technology

[0002] Medium-frequency induction melting furnaces are devices that convert 50Hz AC power into AC power typically ranging from 1000Hz to 10000Hz. They utilize the principle of electromagnetic induction to generate eddy currents in metal materials, causing the metal materials to heat up and thus achieving rapid melting. Compared with traditional oil-fired furnaces and gas-fired furnaces, medium-frequency induction melting furnaces do not produce combustion exhaust gases such as sulfur dioxide and nitrogen oxides during operation, nor do they produce a large amount of dust, resulting in less environmental pollution.

[0003] Currently, existing medium-frequency induction melting furnaces typically have an open top design. This facilitates material feeding and allows workers to easily remove impurities floating on the molten iron using shovels. However, it is inconvenient to seal the furnace top when moving the furnace. During the transfer and unloading of the induction furnace, this open design can easily cause the molten iron inside to spill due to shaking or inertia, resulting in serious accidents and affecting the safety of the operation. Utility Model Content

[0004] The purpose of this utility model is to provide a medium-frequency induction melting furnace that facilitates unloading, in order to solve the problem mentioned in the background art that the existing medium-frequency induction melting furnace is inconvenient to seal the furnace top when transferring the furnace body, and that the molten iron inside the furnace body is prone to spillage due to shaking or inertia during the transfer process when transferring and unloading the induction furnace, which affects the safety of the operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medium-frequency induction melting furnace for easy unloading, comprising a frame,

[0006] A heating chamber is provided at one end of the frame, and an L-shaped mounting bracket is installed at the midpoint of the frame. A fixing column is fixed below the top of the L-shaped mounting bracket, and a fixing plate is fixed at the bottom of the fixing column. L-shaped lifting brackets are provided through both ends of the fixing plate. A melting furnace is provided at the bottom of the L-shaped lifting bracket. An induction coil is provided inside the heating chamber. Lifting components are provided on both sides of the fixing plate. The lifting components are used to drive the L-shaped lifting bracket to move vertically. A cover plate is provided below the fixing plate.

[0007] The L-shaped mounting bracket is equipped with a rotating mechanism, which is used to drive the L-shaped mounting bracket to rotate.

[0008] Preferably, the lifting assembly includes a hydraulic cylinder, which is fixed to both ends of the fixed plate, and a connecting plate is fixed to the output end of the hydraulic cylinder. The connecting plate is fixedly connected to the top of the L-shaped lifting frame.

[0009] In the above technical solution, the hydraulic cylinder drives the connecting plate to rise, which in turn drives the two sets of L-shaped lifting frames to lift.

[0010] Preferably, a shelf is fixed to one end of the frame.

[0011] In the above technical solution, the platform can temporarily store the melting furnace after it has been transferred.

[0012] Preferably, the fixing plate has through holes at both ends, the L-shaped lifting frame is located in the through holes, and the inner wall of the through holes is provided with a number of sets of balls, which are in contact with the L-shaped lifting frame.

[0013] In the above technical solution, the through hole can guide the vertical movement of the L-shaped lifting frame, and the ball can reduce the friction when the L-shaped lifting frame moves vertically in the through hole, thereby reducing wear and increasing service life.

[0014] Preferably, the bottom ends of the fixing plate are fixed with fixing cylinders, and a telescopic rod is provided in the fixing cylinder. A spring is sleeved on the outside of the telescopic rod, and the two ends of the spring are respectively connected to the fixing cylinder and the cover plate.

[0015] In the above technical solution, the setting of the fixed cylinder, telescopic rod and spring allows the cover plate to adaptively expand and contract after the melting furnace abuts against it, so as to better fit the top of the melting furnace and seal it.

[0016] Preferably, the rotating mechanism includes a first gear, which is mounted on the bottom of an L-shaped mounting frame. A motor is provided on the side of the frame, and the output end of the motor is connected to a second gear, which meshes with the first gear.

[0017] In the above technical solution, the motor drives the second gear to rotate, which in turn drives the meshing first gear to rotate, thereby driving the L-shaped mounting frame, the fixed column, and the lifted melting furnace to rotate and transfer.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this medium-frequency induction melting furnace facilitates material unloading.

[0019] (1) The two sets of L-shaped lifting frames can lift the two sides of the melting furnace, and the lifting components can drive the two sets of L-shaped lifting frames and the melting furnace to rise. As the L-shaped lifting frames and the melting furnace rise, the cover plate located below the fixed plate will seal the top of the melting furnace. In this way, when the melting furnace is transferred and unloaded, it can effectively prevent the molten iron inside the melting furnace from splashing due to inertia or shaking, thus ensuring the safety of transferring the molten iron inside the furnace.

[0020] (2) By driving the second gear to rotate through the motor, the second gear can drive the meshing first gear to rotate, thereby driving the L-shaped mounting frame, the fixed column and the lifted melting furnace to rotate and transfer. During the rotation and transfer process, the center of gravity of the melting furnace is relatively fixed, and its movement trajectory is to make a circular motion around the center point of the L-shaped mounting frame. Compared with the linear movement through the guide rails, the rotational motion is more conducive to maintaining the balance and stability of the furnace body and reducing the risk of shaking and tilting caused by the shift of the center of gravity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a medium-frequency induction melting furnace that facilitates material unloading, such as... Figure 1 , Figure 2 and Figure 3As shown, a heating chamber is provided at one end of the frame 1, and an L-shaped mounting bracket 3 is installed at the midpoint of the frame 1. A fixing column 4 is fixed below the top of the L-shaped mounting bracket 3, and a fixing plate 5 is fixed at the bottom of the fixing column 4. An L-shaped lifting bracket 6 is provided through both ends of the fixing plate 5. A melting furnace 7 is provided at the bottom of the L-shaped lifting bracket 6. An induction coil 8 is provided inside the heating chamber. Lifting components are provided on both sides of the fixing plate 5. The lifting components are used to drive the L-shaped lifting bracket 6 to move vertically. A cover plate 12 is provided below the fixing plate 5.

[0027] The L-shaped mounting bracket 3 is equipped with a rotating mechanism 16, which is used to drive the L-shaped mounting bracket 3 to rotate.

[0028] like Figure 1 and Figure 2 As shown, the lifting assembly includes a hydraulic cylinder 10, which is fixed to both ends of the fixed plate 5, and a connecting plate 11 is fixed to the output end of the hydraulic cylinder 10. The connecting plate 11 is fixedly connected to the top of the L-shaped lifting frame 6.

[0029] like Figure 1 As shown, a shelf 2 is fixed to one end of the frame 1.

[0030] like Figure 2 and Figure 3 As shown, the fixed plate 5 has through holes at both ends, the L-shaped lifting frame 6 is located in the through holes, and several sets of balls 9 are provided on the inner wall of the through holes, the balls 9 are in contact with the L-shaped lifting frame 6.

[0031] like Figure 2 and Figure 3 As shown, the bottom ends of the fixed plate 5 are fixed with fixed cylinders 13, and the fixed cylinders 13 are provided with telescopic rods 14. The telescopic rods 14 are fitted with springs 15 on the outside, and the two ends of the springs 15 are connected to the fixed cylinders 13 and the cover plate 12 respectively.

The induction coil 8 melts the metal inside the furnace 7. After the metal melts, the hydraulic cylinder 10 is opened, causing the connecting plate 11 to rise. This, in turn, lifts the two sets of L-shaped lifting frames 6 and the melting furnace 7. As the furnace 7 rises, it eventually presses against the cover plate 12 below the fixed plate 5. 2. The top of the melting furnace 7 will be sealed. The setting of the fixed cylinder 13, telescopic rod 14 and spring 15 allows the cover plate 12 to adaptively extend and retract after the melting furnace 7 is against it, so as to better fit the top of the melting furnace 7. Then the motor 1603 can be turned on to drive the gear 1602 to rotate, so that the gear 1602 drives the gear 1601, L-shaped mounting bracket 3, fixed column 4 and the lifted melting furnace 7 to rotate and transfer to the platform 2, so that the molten iron can be unloaded later.
