[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides a technical solution: As Figures 1-4 shown, in this embodiment, a metallurgical furnace for iron and steel metallurgy includes: a bracket 1;

[0022] Rotating shafts 2, the number of which is two. The two rotating shafts 2 are respectively rotatably installed at both ends of the top of the bracket 1, and a furnace body 3 is fixedly installed between the two rotating shafts 2;

[0023] Adjusting component 4, the adjusting component 4 is installed on the bracket 1 and is used to drive the furnace body 3 to rotate an angle. One end of each of the two rotating shafts 2 is fixedly installed with a rotating plate 5, and lifting plates 6 are slidably sleeved on the tops of the two rotating plates 5; One side of the rotating plate 5 is fixedly installed with a cylinder 11, and the telescopic end of the cylinder 11 is connected to the bottom of the lifting plate 6. A rotating motor 15 for driving the rotating plate 8 to rotate is fixedly installed on the top of the top cover 7. The adjusting component 4 includes a moving screw 41 rotatably installed on the bracket 1, a driving motor 42 is fixedly installed on the bracket 1, the output end of the driving motor 42 is fixedly connected to one end of the moving screw 41, a slide plate 43 is slidably installed on the bracket 1, the bottom end of the slide plate 43 is threadedly connected to the moving screw 41, and the top end of the slide plate 43 contacts the furnace body 3.

[0024] Top cover 7, the top cover 7 is fixedly installed between the two lifting plates 6. A rotating plate 8 is rotatably installed at the bottom of the top cover 7, two scrapers 9 are slidably installed at the bottom of the rotating plate 8, and a moving component 10 for driving the two scrapers 9 to approach or move away from each other is installed at the bottom of the rotating plate 8. The moving component 10 includes a bidirectional threaded rod 101 rotatably installed at the bottom of the rotating plate 8, and the two scrapers 9 are both threadedly connected to the bidirectional threaded rod 101. Handles are fixedly installed at both ends of the bidirectional threaded rod 101, and one side of the scraper 9 is attached to the outer peripheral side of the furnace body 3.

[0025] The furnace body 3 is installed on the bracket 1 through two rotating shafts 2, allowing the furnace body 3 to rotate a certain angle, so as to facilitate pouring out molten iron and cleaning the inside of the furnace body 3.

[0026] The adjusting component 4 consists of a moving screw 41, a driving motor 42 and a sliding plate 43. The driving motor 42 is connected to one end of the moving screw 41 through its output end, and the other end of the moving screw 41 is threadedly connected to the sliding plate 43. Through the control of the driving motor 42, the moving screw 41 can rotate, thereby driving the sliding plate 43 to slide on the bracket 1, so as to push the furnace body 3 to rotate, realizing the adjustment of the rotation angle of the furnace body 3, and gradually making the furnace body 3 rotate to be horizontally placed, facilitating the pouring of the molten iron in the furnace body 3 and cleaning the dust and impurities on the inner wall of the furnace body 3.

[0027] The top cover 7 is fixed between the two lifting plates 6, and a rotating plate 8 is installed at its bottom. The rotating plate 8 can rotate, and two scraping plates 9 are installed at the bottom. The scraping plates 9 are controlled by a moving component 10, and the moving component 10 consists of a bidirectional threaded rod 101. The scraping plates 9 are threadedly connected to the bidirectional threaded rod 101. When the bidirectional threaded rod 101 rotates, it can drive the scraping plates 9 to approach or move away from each other.

[0028] During the working process, use the handle to drive the bidirectional threaded rod 101 to rotate, so that the two scraping plates 9 approach each other. At this time, the scraping plates 9 act as stirring rods. Start the rotating motor 15 to drive the rotating plate 8 to rotate, thereby driving the two scraping plates 9 to rotate, stirring the raw materials in the furnace body 3, ensuring uniform mixing of the materials, and improving the reaction efficiency. At the same time, this stirring also helps to break up the material agglomeration and prevent adhesion to the furnace wall. The lifting plates 6 are connected to the rotating shaft 2 through the rotating plates 5 and are controlled by the air cylinders 11 to lift. This design allows the lifting plates 6 to adjust the height according to needs, so as to drive the top cover 7 to lift, thereby adjusting the length of the scraping plates 9 in the furnace body 3, facilitating the full stirring of the materials in the furnace body 3, improving the stirring efficiency, and the scraping plates 9 can be moved out of the furnace body 3 under the action of the air cylinders 11, facilitating the cleaning of the inside of the furnace body 3 and also facilitating the cleaning of the scraping plates 9.

[0029] When the scraping plates 9 move away from each other and fit against the inner wall of the furnace body 3, they can scrape the dust and impurities on the inner wall, keeping the inside of the furnace body 3 clean. This cleaning process not only helps to maintain the thermal efficiency of the furnace body 3, but also prevents the product quality from being affected due to the accumulation of impurities.

[0030] As Figure 2 shown, electric push rods 12 are fixedly inserted at both ends of the top of the bracket 1, and a limit plate 13 is fixedly installed at the telescopic end of the electric push rod 12.

[0031] Start the electric push rod 12 to drive the limit plate 13 to approach the vertical furnace body 3, so as to clamp and limit the furnace body 3 and prevent it from rotating randomly.

[0032] As Figure 3As shown, two rollers 14 are rotatably installed on the top of the skateboard 43, and the two rollers 14 are symmetrically distributed and rotatably installed at both ends of the top of the skateboard 43.

[0033] When the rollers 14 assist the furnace body 3 to rotate, it avoids the friction between the skateboard 43 and the outer peripheral side of the furnace body, causing wear on the outer surface of the furnace body 3. The rollers 14 are in direct contact with the furnace body 3, and their rotating connection structure facilitates the pushing of the furnace body 3.

[0034] The present utility model provides a metallurgical furnace for iron and steel metallurgy, and the specific working principle is as follows:

[0035] During the working process, pig iron is put into the furnace body 3 for melting. The two-way threaded rod 101 is rotated by using the handle, so that the two scrapers 9 approach each other. At this time, the scrapers 9 act as stirring rods to stir the raw materials in the furnace body 3, ensuring uniform mixing of the materials and improving the reaction efficiency. At the same time, this stirring also helps to break up the material agglomeration and prevent adhesion to the furnace wall. The lifting plate 6 is connected to the rotating shaft 2 through the rotating plate 5 and is controlled by the cylinder 11 to lift. This design allows the lifting plate 6 to adjust the height as needed, so as to drive the top cover 7 to lift, thereby adjusting the length of the scraper 9 in the furnace body 3, facilitating comprehensive stirring of the materials in the furnace body 3, improving the stirring efficiency, and the scraper 9 can be moved out of the furnace body 3 under the action of the cylinder 11, facilitating the cleaning of the inside of the furnace body 3 and at the same time facilitating the cleaning of the scraper 9. When it is necessary to pour out the molten iron, through the control of the drive motor 42, the moving screw 41 can rotate, and then drive the skateboard 43 to slide on the bracket 1, thereby driving the furnace body 3 to rotate, realizing the adjustment of the rotation angle of the furnace body 3, gradually making the furnace body 3 rotate to be horizontally placed, pouring out the molten iron in the furnace body 3, and then when it is necessary to clean the inner wall of the furnace body, rotate the moving screw 41, the two scrapers 9 move away from each other and fit against the inner wall of the furnace body 3, start the drive motor 42 to drive it to rotate, and can scrape the dust and impurities on the inner wall, keeping the inside of the furnace body 3 clean. The horizontally placed furnace body 3 is convenient for cleaning out the dust and impurities falling on the inner wall.
