Description

Technical Field

[0001] This utility model belongs to the technical field of casting production equipment, specifically relating to a medium-frequency furnace for quantitative pouring of molten iron. Background Technology

[0002] In the casting production process, medium-frequency furnaces are commonly used equipment for melting molten iron. The quantitative extraction of molten iron is a key link to ensure the quality of castings and production efficiency. Therefore, it is necessary to design a medium-frequency furnace for quantitative extraction of molten iron.

[0003] In traditional medium-frequency furnaces, the amount of molten iron poured out is mainly controlled by the operator's experience in manually adjusting the furnace tilt angle. This method has low precision, is not suitable for beginners, and has a large margin of error. It is also difficult to control the tilting force and speed, which can easily lead to spillage of molten iron, wasting the iron and posing certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a medium-frequency furnace with a simple structure and reasonable design for quantitative pouring of molten iron in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A medium-frequency furnace for quantitative hot metal extraction includes a base plate. A U-shaped fixing frame is fixedly installed on one side of the top of the base plate. A protective component slides through the inner top of the U-shaped fixing frame. A furnace body component is rotatably installed on the bottom of the inner side of the U-shaped fixing frame, positioned below the protective component. A drive component that cooperates with the furnace body component is fixedly installed at the middle position of the side of the U-shaped fixing frame away from the base plate. A material handling component that cooperates with the furnace body component is slidably installed on the other side of the top of the base plate.

[0007] As a further optimization of this utility model, the protective component includes two limiting rods that slide through to the top ends of the U-shaped fixing frame. A protective cover is installed at the bottom of the two limiting rods. A feed port is opened inside the protective cover. A spring that is fixed to the top of the U-shaped fixing frame is fitted at the middle position of the outer side of the two limiting rods.

[0008] As a further optimization of this utility model, the furnace body assembly includes a furnace shell rotatably mounted on the bottom of the inner side of a U-shaped fixing frame, and the furnace shell is placed below and in contact with the protective cover. A crucible connected to the inside and outside of the feed inlet is fixedly installed in the middle position inside the furnace shell, and a heating structure fitted onto the outside of the crucible is fixedly installed inside the furnace shell.

[0009] As a further optimization of this utility model, the driving component includes a U-shaped mounting bracket fixedly installed at the middle position on the side of the U-shaped fixing frame away from the bottom plate. Electric push rods are fixedly installed at both ends of the inner side of the U-shaped mounting bracket. Slide rails are fixedly installed at the middle position of the top of both ends of the furnace shell. Sliding sliders extending to the outside are slidably connected to the top of the inner side of the two slide rails. The ends of the two sliders that are far apart are rotatably connected to the output ends of the two electric push rods.

[0010] As a further optimization of this utility model, the material handling component includes two guide grooves opened at both ends of the top of the bottom plate. Inside the two guide grooves, on the side near the U-shaped mounting bracket, there are guide sliders extending to the outside. The top of the two guide sliders is jointly installed with a placement groove. The bottom of the placement groove is filled with a material handling groove that cooperates with the crucible. The top of both ends of the furnace shell near the guide grooves is rotatably installed with hinge rods. The ends of the two hinge rods away from the furnace shell are rotatably connected to the two ends of the placement groove.

[0011] As a further optimization of this utility model, the crucible and the protective cover are respectively provided with a furnace nozzle and an extension plate on the side near the material receiving trough. The extension plate covers the top of the furnace nozzle and cooperates with the material receiving trough.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the structural design of the drive component, can easily realize the electric tilting function of the furnace body component, which facilitates the stability of subsequent tilting and ensures the quantitative function of subsequent tilting. Compared with the existing manual tilting method, the electric push tilting of this structural design has a better stability effect and a more stable tilting speed, reducing tilting errors and ensuring the safety of subsequent tilting.

[0014] 2. Through the structural design of the furnace body assembly and the material handling assembly, this utility model can easily realize the pouring and material handling operation of molten iron.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3As shown, a medium-frequency furnace for quantitative molten iron pouring includes a base plate 1. The base plate 1 facilitates the fixing and placement of subsequent components. A U-shaped fixing frame 6 is fixedly installed on one side of the top of the base plate 1. A furnace body assembly 5 is hinged to the bottom of the inner side of the U-shaped fixing frame 6. The structural design of the furnace body assembly 5 facilitates the storage and melting of iron materials. The furnace body assembly 5 includes a furnace shell 500 hinged to the bottom of the inner side of the U-shaped fixing frame 6. Rotating rods are fixedly installed at the middle positions of the bottom of both ends of the furnace shell 500, and the ends of the two rotating rods that are far apart are connected to the U-shaped fixing frame 6. The inner side of the frame 6 is rotatably connected, and a crucible 501 is fixedly installed in the middle position inside the furnace shell 500. The crucible 501's own structural design facilitates the placement of iron materials and subsequent heating and melting. A furnace spout extending to the outside of the furnace shell 500 is opened on one side of the crucible 501, which facilitates the pouring and unloading of molten iron. A heating structure 502, which fits onto the outside of the crucible 501, is fixedly installed inside the furnace shell 500. The heating structure 502 includes an induction coil and a magnetic yoke. The induction coil can generate an alternating magnetic field by passing a medium-frequency current, causing eddy currents in the metal. The furnace heats up and melts, while the magnetic yoke, constructed from stacked silicon steel sheets, constrains leakage magnetic flux and improves energy efficiency. A protective component 3, which slides through the inner top of the U-shaped fixing frame 6 and covers the furnace body assembly 5, is conveniently designed to protect the furnace from molten iron splashing during material addition. The protective component 3 includes two limiting rods 303 that slide through to both ends of the inner top of the U-shaped fixing frame 6. A protective cover 300, which covers the top of the crucible 501, is installed at the bottom of both limiting rods 303. The interior of the protective cover 300 has an opening that connects to the crucible 501. The internally connected feed inlet 301 is later covered and protected by the protective cover 300 to cover the top of the crucible 501. The feed inlet 301 allows for easy addition of materials later. An extension plate is fixedly installed on one side of the protective cover 300, and the extension plate covers the furnace nozzle on the top side of the crucible 501. A spring 302, which is fixed to the top of the U-shaped fixing frame 6, is fitted at the middle position of the outer side of the two limiting rods 303. A limiting ring is fixedly installed at the middle position of the outer side of the two limiting rods 303, and the top of the limiting ring is fixedly connected to the bottom of the spring 302.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a drive assembly 4, which cooperates with the furnace body assembly 5, is fixedly installed at the middle position of the U-shaped fixed frame 6 on the side away from the bottom plate 1. Through the structural design of the drive assembly 4, the furnace body assembly 5 can be driven to rotate along the rotating rod, so as to facilitate the automatic tilting and unloading of materials in the later stage and ensure the stability and safety of the tilting and unloading of materials in the later stage. The drive assembly 4 includes a U-shaped mounting frame 400 fixedly installed at the middle position of the U-shaped fixed frame 6 on the side away from the bottom plate 1. Electric push rods 401 are fixedly installed at both ends of the inner side of the U-shaped mounting frame 400. Connecting blocks are fixedly installed at the output ends of the two electric push rods 401. Rotating rods are rotatably installed at the ends of the two connecting blocks that are close to each other. Slide rails 403 are fixedly installed at the middle position of the top of both ends of the furnace shell 500. Sliding sliders 402 extending to the outside are slidably connected to the top of the inner side of the two slide rails 403. The ends of the two sliders 402 that are far apart are connected to the outer side of the slide rails 403. The two electric push rods 401 are rotatably connected at their output ends. The operation of the electric push rods 401 allows the slider 402 to slide inside the slide rail 403, and during this sliding process, it also rotates along the rotating rod. Simultaneously, when the electric push rods 401 drive the slider 402 to slide inside the slide rail 403, they also drive the furnace body assembly 500 to hinge and rotate along the rotating rod, facilitating the subsequent pouring of molten iron. During the pouring process, the hinged rotation of the furnace shell 500 also pushes the protective cover 300, which in turn moves the limiting rod 303 upwards inside the U-shaped fixing frame 6, compressing the spring 302 and facilitating the opening of the protective cover 300. Furthermore, when the furnace shell 500 is reset, the top side cooperates with the bottom side of the protective cover 300 to lift the cover, facilitating its resetting and closing.

[0024] like Figure 1As shown, a material handling component 2, which cooperates with the furnace body component 5, is slidably installed on the other side of the top of the base plate 1. The design of the material handling component 2 facilitates the collection and storage of molten iron poured out later, making it convenient for operators to use directly. The material handling component 2 includes two guide grooves 202 located at both ends of the top of the base plate 1. Limit grooves are provided at both ends of the guide grooves 202. Guide sliders 203 extending to the outside are slidably connected to the side of the two guide grooves 202 closest to the U-shaped mounting bracket 400. Both ends of the guide slide 202 are fixedly installed with limit sliders extending into the limit groove, and the limit groove and the limit slider cooperate to improve the stability of the sliding connection between the guide groove 202 and the guide slide 203. The top of the two guide sliders 203 are jointly installed with a placement groove 201. The bottom of the placement groove 201 is filled with a material taking groove 204 that cooperates with the crucible 501. The top of both ends of the material taking groove 204 are fixedly installed with handles, and the outside of the handles is evenly provided with anti-slip texture to facilitate the operation of the operator. The material taking groove 204 is placed in the furnace shell 50. On one side of the furnace shell 500, hinge rods 200 are hingedly installed at the top of both ends near the guide slide 202. The ends of the two hinge rods 200 away from the furnace shell 500 are hingedly connected to both ends of the placement groove 201. Hinges are fixedly installed at the middle positions of both ends of the placement groove 201, and the hingees cooperate with the hinge rods 200. Later, by hinged rotation of the furnace shell 500 and its components, the hinge rods 200 can be driven to hinge and rotate, thereby pushing the placement groove 201 and the material handling groove 204 to drive the guide slider 203. The guide chute 202 slides inside, allowing the material chute 204 to remain aligned with the furnace nozzle during movement. This facilitates the material chute 204 to move away during the tilting of the furnace shell 500 and above, enabling real-time material retrieval during the subsequent tilting process. This eliminates the need for operators to manually change the displacement of the material chute 204 during material retrieval, ensuring convenience and flexibility in subsequent material retrieval. Furthermore, the displacement range of the material chute 204 will never exceed the tilting range of the furnace nozzle, and the specific displacement range can be controlled according to the installation length of the hinge rod 200.

[0025] It should be noted that the initial state of this type of medium-frequency furnace for quantitative molten iron extraction during use is as follows: Figure 1As shown, the operator can then add materials to the crucible 501 through the feed inlet 301. When the power is connected, the heating structure 502 facilitates the heating and melting of the materials inside the crucible 501. Simultaneously, the protective cover 300 allows for easy sealing of the top of the crucible 501, preventing splashing of molten iron during the heating process and ensuring safety during subsequent heating. When the electric push rod 401 drives the slider 402 to slide within the slide rail 403, it also drives the furnace body assembly 500 to rotate along the rotating rod, facilitating the subsequent pouring of molten iron. During pouring, the hinged rotation of the furnace shell 500 pushes the protective cover 300, which in turn moves the limiting rod 303 upwards within the U-shaped fixing frame 6, compressing the spring 302 and facilitating the opening of the protective cover 300. Meanwhile, the furnace shell 500... During reset, the protective cover 300 can be lifted by engaging with the bottom side of the protective cover 300, facilitating its reset and closing. Simultaneously, the hinged rotation of the furnace shell 500 and its components drives the hinge rod 200 to rotate, which in turn pushes the placement slot 201 and the material retrieval slot 204, causing the guide slider 203 to slide within the guide groove 202. This ensures that the material retrieval slot 204 remains aligned with the furnace nozzle during movement, allowing it to move away from the furnace shell 500 and its components during tilting. This facilitates real-time material retrieval during subsequent tilting without requiring manual adjustment of the material retrieval slot 204's displacement, ensuring convenience and flexibility in subsequent material retrieval. Furthermore, the displacement range of the material retrieval slot 204 will never exceed the tilting range of the furnace nozzle, and the specific displacement range can be controlled based on the installation length of the hinge rod 200.

[0026] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
