[0021] In this embodiment, the medium frequency furnace body 1 is the main part for smelting metal, and is provided with a heating layer 2 and a heat preservation layer 3. The metal is melted by the high temperature generated by the heating layer 2, while the heat preservation layer 3 ensures the stability of the temperature in the furnace and improves the smelting efficiency.

The adjustment mechanism is arranged on the cover 4, which is used to adjust the size of the movable plate 7 covering the through hole 5. Through the adjustment mechanism, the operator can easily control the movement of the movable plate 7, so as to adjust the opening size of the through hole 5 as needed to meet different smelting needs.

[0022] In a further preferred embodiment of the utility model, the adjusting mechanism includes a rack 8, a fixed cover 9, a mounting groove 10, a fixed gear 11 and a driving mechanism, the rack 8 is fixedly mounted in a groove opened on the movable plate 7, the fixed cover 9 is fixedly mounted on the cover 4, the mounting groove 10 is opened on the cover 4, the fixed gear 11 is rotatably mounted on the fixed cover 9, the fixed gear 11 passes through the mounting groove 10 and engages with the rack 8, and the driving mechanism is arranged in the fixed cover 9 for driving the fixed gear 11 to rotate.

[0023] In this embodiment, the adjustment mechanism allows the operator to accurately control the movement of the movable plate 7 through simple operations, thereby adjusting the opening size of the through-port 5. The rack 8 is fixedly mounted in the groove provided on the movable plate 7. This installation method is both stable and does not affect the sliding of the movable plate 7. The existence of the rack 8 enables the movement of the movable plate 7 to be coordinated with the rotation of the fixed gear 11, thereby achieving precise displacement control. The fixed cover 9 is fixedly mounted on the cover 4, providing a stable installation environment for the fixed gear 11 and the driving mechanism. The mounting groove 10 is provided on the cover 4, so that the fixed gear 11 can pass through the mounting groove 10 to mesh with the rack 8, and the rotation of the fixed gear 11 can directly drive the movement of the rack 8, thereby driving the movable plate 7 to slide in the movable groove 6. The driving mechanism is arranged in the fixed cover 9, and is used to drive the fixed gear 11 to rotate. This driving method is both simple and efficient, and can ensure the stability and accuracy of the rotation of the fixed gear 11.

[0024] In a further preferred embodiment of the utility model, the driving mechanism includes two pulleys 12, a conveyor belt 13, a first bevel gear 14, a drive motor 15 and a second bevel gear 16, the two pulleys 12 are rotatably mounted on the fixed cover 9, any of the pulleys 12 is fixedly connected to the fixed gear 11, the conveyor belt 13 is sleeved on the two pulleys 12, the first bevel gear 14 is fixedly mounted on the pulley 12, the drive motor 15 is fixedly mounted on the fixed cover 9, the second bevel gear 16 is fixedly mounted on the output shaft of the drive motor 15, and the second bevel gear 16 is meshed with the first bevel gear 14.

[0025] In this embodiment, both pulleys 12 are rotatably mounted on the fixed cover 9 to ensure the stability and reliability of the pulleys 12.

When one of the pulleys 12 rotates, the transmission of the conveyor belt 13 can drive the other pulley 12 to rotate synchronously, thereby achieving a smooth transmission of power and reducing energy loss. The first bevel gear 14 is fixedly mounted on one of the pulleys 12, and the drive motor 15 is fixedly mounted on the fixed cover 9 to provide power for the entire drive mechanism. The second bevel gear 16 is fixedly mounted on the output shaft of the drive motor 15 and meshes with the first bevel gear 14. When the drive motor 15 is working, its output shaft drives the second bevel gear 16 to rotate, and then drives the first bevel gear 14 and the pulley 12 connected thereto to rotate through the meshing transmission of the bevel gears. The operator only needs to control the start and stop of the driving motor 15 to realize the rotation of the fixed gear 11 and further control the sliding of the movable plate 7.

[0026] In a further preferred embodiment of the utility model, an exhaust port 17 is opened on the intermediate frequency furnace body 1, a fan 18 is fixedly installed on the intermediate frequency furnace body 1, an exhaust pipe 19 is fixedly installed on the air inlet end of the fan 18, and the exhaust pipe 19 is fixedly installed on the intermediate frequency furnace body 1 and arranged corresponding to the exhaust port 17.

[0027] In this embodiment, the exhaust port 17 opened on the medium frequency furnace body 1 is mainly used to discharge the waste gas generated during the smelting process. When smelting metal, a large amount of waste gas and smoke will be generated in the furnace. If these waste gases are not discharged in time, they will not only pollute the working environment, but also pose a threat to the health of the operators. Therefore, the setting of the exhaust port 17 is crucial to ensure the smooth progress of the smelting process and the health and safety of the personnel. In order to discharge the waste gas more effectively, a fan 18 is also fixedly installed on the medium frequency furnace body 1. When the fan 18 is started, it can quickly absorb the waste gas at the exhaust port 17 through the exhaust pipe 19, and discharge the waste gas into the collection and filtration device through the exhaust end of the fan 18. This design not only greatly improves the exhaust gas emission efficiency, but also effectively reduces the accumulation of waste gas in the furnace, further improving the safety of the smelting process. The coordinated use of the fan 18 and the exhaust pipe 19 also makes the exhaust gas emission more concentrated and orderly, reduces the diffusion of waste gas in the working environment, and thus reduces the health impact on the operators. At the same time, this design also helps to maintain a stable temperature in the smelting furnace and improves smelting efficiency.

[0028] In a further preferred embodiment of the utility model, a supporting mechanism is provided on the medium frequency furnace body 1 for pouring the molten metal, and the supporting mechanism includes two support rods 20, a bottom plate 21, a rotating motor 22 and a placement slot 23. The two support rods 20 are rotatably mounted on the medium frequency furnace body 1, the bottom plate 21 is fixedly mounted on the bottom of the two support rods 20, the rotating motor 22 is fixedly mounted on any of the support rods 20, the output shaft of the rotating motor 22 is fixedly connected to the medium frequency furnace body 1, and the placement slot 23 is opened on the bottom plate 21.

[0029] In this embodiment, the two support rods 20 are rotatably mounted on the medium frequency furnace body 1, providing a stable support foundation for the entire support mechanism. The bottom plate 21 is fixedly mounted on the bottom of the two support rods 20, forming a solid platform for carrying and supporting the molten metal. The rotating motor 22 is fixedly mounted on one of the support rods 20, and its output shaft is fixedly connected to the medium frequency furnace body 1. In this way, when the rotating motor 22 is working, it can drive the medium frequency furnace body 1 to rotate, so as to conveniently adjust the pouring angle of the molten metal. This design makes the pouring process more flexible and convenient, and improves the operating efficiency. In addition, a placement groove 23 is also provided on the bottom plate 21, so that the container containing the liquid metal is prevented from being inside, and the next step of operation is carried out, which is conducive to the fixation of the container. The design of the placement groove 23 takes into account the characteristics and pouring requirements of the molten metal, which can ensure that the molten metal will not overflow or spill during the pouring process, further improving the safety of the operation.

[0030] In a further preferred embodiment of the utility model, the intermediate frequency furnace body 1 and the corresponding position of the through opening 5 are set to be triangular spout shape, and the movable plate 7 is in conflict with the top of the intermediate frequency furnace body 1.

[0031] In this embodiment, the position corresponding to the medium frequency furnace body 1 and the through-port 5 is set to a triangular spout shape. This design not only optimizes the outflow pattern of the molten metal solution, but also makes the solution more concentrated and smooth when pouring. The triangular spout-shaped design can reduce the splashing and spilling of the solution during the pouring process, and improve the accuracy and safety of the operation. The design of the movable plate 7 contacting the top of the medium frequency furnace body 1 ensures the stability and reliability of the movable plate 7 during the sliding process. When the movable plate 7 covers the through-port 5, it can fit tightly on the top of the medium frequency furnace body 1, effectively preventing impurities or objects from accidentally falling into the smelting furnace from the through-port 5. This design not only enhances the safety of the smelting process, but also improves the durability and service life of the equipment.

[0032] In a further preferred embodiment of the present invention, a protrusion is arranged in the movable groove 6, and guide grooves corresponding to the protrusion are arranged on both sides of the movable plate 7.

[0033] In this embodiment, the protrusion is cleverly arranged in the movable groove 6 to ensure that it can be closely matched with the guide grooves on both sides of the movable plate 7. When the movable plate 7 slides in the movable groove 6, the protrusion can move along the track of the guide groove to play a guiding and stabilizing role. It effectively prevents the movable plate 7 from deflecting or shaking during the sliding process, making the adjustment process more accurate and smooth. At the same time, the cooperation between the protrusion and the guide groove also enhances the load-bearing capacity of the movable plate 7, so that it can withstand greater pressure without being easily deformed or damaged. The operator can adjust the movable plate 7 more conveniently, which improves work efficiency and convenience of operation.

[0034] In summary, compared with the relevant technologies, the utility model realizes efficient, safe and convenient operation of the smelting medium frequency furnace in the metal smelting process through a series of ingenious designs and optimizations. Specifically, through the design of the adjustment mechanism, the operator can accurately control the size of the opening, so as to conveniently adjust the pouring speed and flow rate of the molten metal. At the same time, the optimization of the driving mechanism makes the adjustment process more stable and reliable, and improves the durability and service life of the entire equipment. In addition, the addition of components such as exhaust ports, fans and exhaust ducts effectively improves the exhaust gas emission efficiency of the smelting process and reduces the impact on the working environment and the health of operators. The addition of the support mechanism makes the pouring process of the molten metal more flexible and convenient, and improves the operating efficiency.
