Description

Technical Field

[0001] This invention relates to the field of metal manufacturing, and more specifically to a refining furnace for metal manufacturing. Background Technology

[0002] Metal refining furnaces are core equipment in the metallurgical industry. They are used to deeply purify and adjust the composition of crude metals through physical, chemical, or electrochemical means. Their technological development is directly related to the improvement of metal quality and the optimization of energy efficiency in the industry.

[0003] Metal raw materials and flux are loaded into the furnace in proportion. The temperature of the raw materials is increased by preheating, and then the raw materials are melted by electric arc, fuel combustion or induction heating to form liquid metal. After the raw materials become liquid metal, oxidizing gas is added again to oxidize the impurities in the metal to form slag. The slag is then removed by skimming, and a reducing agent is added to reduce the metal oxides back to metal. At the same time, high-alkalinity reducing slag is used to further adsorb impurities such as sulfur and phosphorus. After refining, the molten metal is cast into ingots, slabs or directly continuously cast into shape.

[0004] In existing technologies, impurities in metals are extracted using oxidizing gases and reducing agents. However, these impurities adhere to the furnace walls and are usually removed manually after refining. This method is inefficient, and the high temperature of the furnace makes the workers uncomfortable. As the temperature inside the furnace decreases, the adhered impurities and molten metal solidify, reducing the space inside the furnace and posing other hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a refining furnace for metal manufacturing, solving the following technical problems.

[0006] After the metal is refined in the furnace, impurities will stick to the furnace wall and be removed manually. This removal is very inefficient, and the high temperature of the furnace will make the workers very uncomfortable.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-7 As shown, the present invention is a refining furnace for metal manufacturing, including a moving table 1, a refining furnace 6, pulleys 3, a support arm 2, and a support platform 20; it also includes a cleaning and tapping unit disposed on the support platform 20;

[0042] The refining furnace 6 is located on top of the movable platform 1;

[0043] The pulley 3 is provided in four parts, and each part is rotatably mounted on the bottom of the movable platform 1.

[0044] The support arm 2 is disposed on one side of the mobile platform 1;

[0045] The support platform 20 is fixedly installed at one end of the support arm 2;

[0046] The cleaning and tapping unit is mounted on the support platform 20 and includes a drive assembly, a lifting assembly 30, a scraping assembly 31, and a tapping assembly 32. The drive assembly drives the lifting assembly 30 to move up and down. The drive assembly drives the scraping assembly 31 to rotate. The scraping assembly 31 drives the tapping assembly 32 to move.

[0047] By sliding the pulley 3 at the bottom of the moving platform 1, the metal-refining furnace 6 at the top of the moving platform 1 is sent to the support platform 20 on the support arm 2.

[0048] The drive component on the support platform 20 drives the lifting component 30 to move up and down, sending the scraping component 31 and the striking component 32 set on the lifting component 30 into the refining furnace 6, so that the scraping component 31 and the striking component 32 can clean the impurities adhering to the refining furnace 6.

[0049] While the lifting component 30 is lowered by the drive component, the scraping component 31 is also rotated at the same time. This allows the lifting component 30 to send the scraping component 31 into the refining furnace 6. At the same time, the rotating scraping component 31 will scrape off the impurities adhering to the refining furnace 6, removing impurities, metals and other substances from the furnace wall. This prevents impurities and metals from solidifying and reducing the space inside the refining furnace 6. It also eliminates the need for staff to clean the furnace during operation, thus avoiding discomfort for the staff.

[0050] As the scraping component 31 rotates, the striking component 32 also moves. The moving striking component 32 strikes the inner wall of the refining furnace 6. This is designed to prevent the scraping component 31 from failing to scrape away the impurities in the furnace. The striking component 32 loosens the impurities and metal in the furnace, so that it can work with the scraping component 31 to remove the impurities and metal from the furnace wall.

[0051] Please see Figure 1 , Figure 2 ,and Figure 3 As shown, the drive assembly includes a support plate 14, a drive motor 15, and a drive rod 19;

[0052] The lifting assembly 30 includes a working plate 28, a lifting gear 17, and a lifting toothed plate 13;

[0053] The support plate 14 is provided in two parts and is symmetrically arranged on the top of the support platform 20; the drive rod 19 is rotatably mounted on the support plate 14; the drive motor 15 is fixedly mounted on the support plate 14 and is connected to the drive rod 19; the lifting gear 17 is fixedly mounted on the drive rod 19; the lifting tooth plate 13 is slidably mounted on the support platform 20 and meshes with the lifting gear 17; the working plate 28 is fixedly mounted on the bottom of the lifting tooth plate 13.

[0054] The drive rod 19 is driven by the drive motor 15 on the support plate 14. The rotation of the drive rod 19 causes the lifting gear 17 to rotate, which in turn causes the lifting toothed plate 13 to move. The moving lifting toothed plate 13 causes the working plate 28 to descend, thus allowing the scraping component 31 and the knocking component 32, which are set on the working plate 28, to enter the refining furnace 6. The lifting toothed plate 13 penetrates through the support platform 20, and the support plate 14 keeps the drive rod 19 rotating stably.

[0055] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the drive assembly also includes a driven gear 10 and a planetary gear 9;

[0056] The scraping assembly 31 includes a limiting block 27, an internal gear 8, and a scraper 7;

[0057] The limiting block 27 is fixedly mounted on the working plate 28; the internal gear 8 is rotatably mounted on the limiting block 27; the planetary gear 9 is rotatably mounted on the working plate 28 and meshes with the internal gear 8; the driven gear 10 is rotatably mounted at the top center of the working plate 28 and meshes with the planetary gear 9; multiple scrapers 7 are provided and are evenly and equidistantly fixed on the outside of the internal gear 8.

[0058] The driven gear 10 rotates, driving the planetary gear 9 to rotate. The rotating planetary gear 9 causes the internal gear 8 to rotate on the limiting block 27 on the working plate 28. The rotating internal gear 8 causes multiple scrapers 7 to scrape the inner wall of the refining furnace 6, removing impurities and metal from the refining furnace 6 and keeping the inner wall of the refining furnace 6 clean. There are three or more planetary gears 9. The purpose of setting multiple planetary gears 9 is to stably provide power to the internal gear 8 and to prevent the internal gear 8 from being too heavy, which would prevent it from rotating.

[0059] Please see Figure 2 , Figure 5 and Figure 6As shown, the striking assembly 32 includes a striking block 26, a push rod 25, a sliding shaft 24, a limiting sleeve 23, and a connecting plate 29;

[0060] The connecting plates 29 are provided in multiple portions and are fixedly arranged at equal intervals at the bottom of the internal gear 8; the limiting sleeve 23 is fixedly arranged on the connecting plates 29; the sliding shaft 24 is slidably arranged at the bottom of the working plate 28; the pushing rod 25 is movably arranged on the sliding shaft 24 and slides inside the limiting sleeve 23; the striking block 26 is fixedly arranged at the end of the pushing rod 25 away from the sliding shaft 24.

[0061] The rotation of the internal gear 8 causes the working plate 28 to rotate along with it. The rotating working plate 28 causes the limiting sleeve 23, the push rod 25, the striking block 26, and the sliding shaft 24 to move. The sliding shaft 24 slides in a special sliding groove at the bottom of the working plate 28. When the sliding shaft 24 moves, it causes the push rod 25 to slide back and forth in the limiting sleeve 23, thereby allowing the push rod 25 to drive the striking block 26 to strike the impurities and metal in the refining furnace 6, loosening them so that the scraper 7 can easily scrape them away.

[0062] Please see Figure 1 , Figure 2 and Figure 4 As shown, the drive assembly also includes a worm gear 16 and a driven worm 11;

[0063] The worm gear 16 is fixedly mounted on the drive rod 19; the driven worm 11 is fixedly mounted on the top of the driven gear 10, and the driven worm 11 meshes with the worm gear 16.

[0064] The worm gear 16 is rotated by the drive rod 19. The rotating worm gear 16 meshes with the driven worm 11, thereby causing the driven worm 11 and the driven gear 10 to rotate. This allows the internal gear 8 to rotate for cleaning. The worm gear 16 only has half of its teeth. When it rotates to the side without teeth, the driven worm 11 will not rotate.

[0065] Please see Figures 1 to 7 As shown, a limiting plate 12 is fixedly connected to the working plate 28; there are two limiting plates 12, which are symmetrically arranged on the top of the working plate 28.

[0066] When the lifting toothed plate 13 drives the working plate 28 to rise or fall, in order to prevent the working plate 28 from tilting or deviating, a limiting plate 12 is set on the working plate 28. The limiting plate 12 passes through the support platform 20 to restrict the working plate 28, so that the working plate 28 can rise or fall smoothly.

[0067] Please see Figure 1 , Figure 3 and Figure 6 As shown, a spring 18 is sleeved on the lifting tooth plate 13; the two ends of the spring 18 are fixedly connected to the support platform 20 and the working plate 28 respectively.

[0068] When the lifting gear 17 drives the lifting toothed plate 13 to descend, it will stretch the spring 18 sleeved on the lifting toothed plate 13. The lifting gear 17 is set with half teeth. When the lifting gear 17 rotates to the side without teeth, the lifting toothed plate 13 will lose the downward force. At this time, the spring 18 will release the elastic potential energy of the stretch, allowing the working plate 28 and the lifting toothed plate 13 to move upward, allowing the working plate 28 to detach from the refining furnace 6.

[0069] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a fixed screw 21 is rotatably connected to the movable platform 1; a fixed motor 4 is fixedly connected to one end of the movable platform 1; the fixed motor 4 is connected to the fixed screw 21; a movable block 22 is rotatably connected to the fixed screw 21; two movable blocks 22 are provided and symmetrically arranged on the fixed screw 21; a fixed clamp 5 is fixedly connected to the top of the movable block 22.

[0070] The fixed screw 21 is driven by the fixed motor 4 to rotate. The fixed screw 21 is set to be bidirectional thread. When the fixed screw 21 rotates, it will cause the two moving blocks 22 to move inward or outward at the same time, thereby driving the fixed clamp 5 on the top of the moving block 22 to clamp the furnace 6 or release the furnace 6. This allows the moving platform 1 to keep the furnace 6 stable when it moves.

[0071] The working principle of the present invention is as follows: the metal-refining furnace 6 at the top of the moving platform 1 is moved to the support platform 20 on the support arm 2 by sliding the pulley 3 at the bottom of the moving platform 1.

[0072] The drive component on the support platform 20 drives the lifting component 30 to move up and down, sending the scraping component 31 and the striking component 32 set on the lifting component 30 into the refining furnace 6, so that the scraping component 31 and the striking component 32 can clean the impurities adhering to the refining furnace 6.

[0073] While the lifting component 30 is lowered by the drive component, the scraping component 31 is also rotated at the same time. This allows the lifting component 30 to send the scraping component 31 into the refining furnace 6. At the same time, the rotating scraping component 31 will scrape off the impurities adhering to the refining furnace 6, removing impurities, metals and other substances from the furnace wall. This prevents impurities and metals from solidifying and reducing the space inside the refining furnace 6. It also eliminates the need for staff to clean the furnace during operation, thus avoiding discomfort for the staff.

[0074] As the scraping component 31 rotates, the striking component 32 also moves. The moving striking component 32 strikes the inner wall of the refining furnace 6. This is designed to prevent the scraping component 31 from failing to scrape away the impurities in the furnace. The striking component 32 loosens the impurities and metal in the furnace, so that it can work with the scraping component 31 to remove the impurities and metal from the furnace wall.

[0075] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
