Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a protective device for the lining of a medium-frequency furnace. Background Technology

[0002] In modern industrial production, medium-frequency furnaces are widely used in the smelting of both non-ferrous and ferrous metals due to their high efficiency and precision. From automotive parts manufacturing to the processing of metal raw materials for high-end electronic products, medium-frequency furnaces play a crucial role.

[0003] The furnace lining of an intermediate frequency furnace is an important structure on the inner wall. However, in the traditional process of using an intermediate frequency furnace, materials need to be poured into the furnace through the furnace opening. However, the poured materials are prone to collision with the furnace lining, which can easily cause damage to the furnace lining. Therefore, this utility model proposes an intermediate frequency furnace lining protection device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective device for the lining of a medium-frequency furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medium-frequency furnace lining protection device includes a base and a furnace body. The inner wall of the furnace body is provided with an inner lining body, and the inner bottom of the furnace body is provided with an arc-shaped furnace bottom. The upper end of the arc-shaped furnace bottom is fixedly connected to a feeding mechanism for feeding materials. The feeding mechanism includes a fixing rod fixedly connected to the upper end of the arc-shaped furnace bottom. A spiral blade is fixedly connected to the outer wall of the fixing rod, and a side plate is fixedly connected to the outer wall of the spiral blade.

[0007] Preferably, the upper end of the base is fixedly connected to two symmetrically arranged vertical plates.

[0008] Preferably, each of the two vertical plates has a rotating rod rotatably connected to one end facing the other, and the two rotating rods have one end fixedly connected to the side wall of the furnace body.

[0009] Preferably, an opening is provided at the top of the furnace body.

[0010] Preferably, a first gear is fixedly sleeved at the end of one of the rotating rods, a motor is fixedly connected to the side wall of the vertical plate, and a second gear that meshes with the first gear is fixedly connected to the end of the output shaft of the motor.

[0011] Preferably, a feeding trough is provided at the upper end of the furnace body.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a feeding mechanism, when materials need to be poured into the furnace, the materials are placed on the spiral blades. Under the action of gravity, the materials slide down along the spiral blades. At the same time, the side plates block the materials, preventing them from sliding out from the side. The materials slide down slowly from the spiral blades, thus buffering the materials and effectively preventing them from directly impacting the furnace lining and causing damage to the furnace lining, thereby improving the protection of the furnace lining.

[0014] 2. By setting up a motor, a first gear, and a second gear, when the molten material needs to be poured out after metallurgy is completed, the output shaft of the motor can be driven to rotate, which in turn drives the first gear to rotate, which in turn drives the second gear meshing with it to rotate, thereby driving the rotating rod to rotate, which in turn drives the furnace body to rotate, causing the furnace body to tilt and pour out the molten material inside through the feeding chute, which facilitates material discharge and improves efficiency.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-5A medium-frequency furnace lining protection device includes a base 1 and a furnace body 8. An inner lining body 6 is provided on the inner wall of the furnace body 8. An arc-shaped furnace bottom 10 is provided at the inner bottom of the furnace body 8. A feeding mechanism for feeding materials is fixedly connected to the upper end of the arc-shaped furnace bottom 10. The feeding mechanism includes a fixing rod 11 fixedly connected to the upper end of the arc-shaped furnace bottom 10. A spiral blade 12 is fixedly connected to the outer wall of the fixing rod 11. A side panel 13 is fixedly connected to the outer wall of the spiral blade 12. An opening is provided at the top of the furnace body 8.

[0023] Specifically, the upper end of the base 1 is fixedly connected to two symmetrically arranged vertical plates 2. The opposite ends of the two vertical plates 2 are rotatably connected to rotating rods 9. The opposite ends of the two rotating rods 9 are fixedly connected to the side wall of the furnace body 8. The end of one of the rotating rods 9 is fixedly sleeved with a first gear 3. The side wall of the vertical plate 2 is fixedly connected to a motor 4. The output shaft of the motor 4 is fixedly connected to a second gear 7 that meshes with the first gear 3.

[0024] Specifically, a feeding trough 5 is provided at the upper end of the furnace body 8. The output shaft of the drive motor 4 rotates, which drives the first gear 3 to rotate, which in turn drives the second gear 7 meshing with it to rotate, thereby driving the rotating rod 9 to rotate, which in turn drives the furnace body 8 to rotate, causing the furnace body 8 to tilt and pour out the molten material inside through the feeding trough 5 for easy discharge.

[0025] When this utility model is in use, when it is necessary to pour materials into the furnace body 8, the materials are placed on the spiral blades 12. Under the action of gravity, the materials slide down along the spiral blades 12. At the same time, under the action of the side plate 13, the materials are blocked, preventing the materials from sliding out from the side. The materials slide slowly down the spiral blades 12, which buffers the materials and effectively prevents the materials from directly impacting the furnace lining and causing damage to the furnace lining, thus improving the protection effect of the furnace lining. When the metallurgy is completed and the molten materials need to be poured out, the output shaft of the drive motor 4 can be rotated, which drives the first gear 3 to rotate, drives the second gear 7 meshing with it to rotate, thereby driving the rotating rod 9 to rotate, driving the furnace body 8 to rotate, so that the furnace body 8 tilts and pours the molten materials inside out through the feeding trough 5 for easy discharge.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
