Description

Technical Field

[0001] The invention provides an energy-saving melting furnace for metal smelting, and particularly relates to the technical field of melting furnaces. Background Art

[0002] A furnace is a production equipment specially used for metal smelting. The furnace in the prior art is divided into an outer furnace and an inner furnace. The inner furnace is also called a crucible. When in use, the crucible containing the molten material is placed in the outer furnace, and the crucible is heated by the heating coil in the outer furnace, so that the molten material in the crucible is melted into liquid metal to achieve metal smelting. During the smelting process, in order to ensure the smelting effect, inert gas is injected into the inner furnace to promote the uniformity of the distribution of components in the molten metal.

[0003] The utility model with authorization announcement number CN221505624U discloses a metal smelting device, which arranges two groups of rods extending outward on both sides of the furnace, and adjusts and locks the furnace height by means of a support bracket cooperating with a locking rod on the inner side of the support rod, so as to adjust the depth of the furnace extending into the heating furnace according to the amount of material in the furnace, thereby avoiding the damage caused by empty burning due to continuous heating of the upper part of the furnace that is not filled with material, and can adjust the position of the furnace extending into the heating furnace according to the actual amount of material melted, and can gather heat in the furnace cavity of the heating furnace, thereby solving the problem of heat waste and improving the phenomenon of empty burning damage caused by heating the upper part of the furnace, and has strong practicality; However, the above-mentioned smelting equipment still has some shortcomings when used: due to the subsequent process of pouring molten metal from the furnace, some metal residues will adhere to the outer surface of the furnace near the pouring part, and a large amount of dust generated during smelting will also adhere to it. If the metal residues and dust on the outer surface of the furnace are not effectively handled, as the residues on the outer wall of the furnace adhere too much, it will seriously affect the thermal conductivity of the furnace, resulting in uneven heating due to the obstruction of metal residues during metal smelting. Moreover, if the metal residues and dust come into contact with the heating coil, it will also cause local overheating of the heating coil, which will not only greatly reduce the service life of the heating coil, but also reduce the heating efficiency of the heating coil, thereby greatly increasing the energy consumption of the furnace.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Example 1: Figures 1 to 4 As shown, an energy-saving furnace for metal smelting comprises a bottom plate 1, on the upper surface of which energy-saving furnace 11 and energy-saving furnace 2 12 are fixedly arranged, a vaporization furnace 13 is arranged between energy-saving furnace 11 and energy-saving furnace 2 12, a flue gas pipe 16 is arranged on one side of energy-saving furnace 11 and energy-saving furnace 2 12, the middle part of flue gas pipe 16 is connected with the inside of vaporization furnace 13, inner furnace 14 is arranged inside energy-saving furnace 11 and energy-saving furnace 2 12, air supply pipe 17 is arranged on one side of energy-saving furnace 11 and energy-saving furnace 2 12 close to flue gas pipe 16, heating coil 18 is arranged on the inner annular surface of energy-saving furnace 11 and energy-saving furnace 2 12, and the above components are all prior art. A furnace cover 15 is slidably arranged above the energy-saving furnace 1 1 and the energy-saving furnace 2 12, and four slide groove plates are symmetrically fixedly connected to the outer ring surface of the top of the energy-saving furnace 1 1 and the energy-saving furnace 2 12. There are four furnace covers 15 in total, and two of them are located directly above the energy-saving furnace 1 11, and the other two furnace covers 15 are located directly above the energy-saving furnace 2 12, and the four furnace covers 15 slide in the corresponding slide groove plates respectively.

[0021] During use: the staff slides away from each other to open the two furnace covers 15 above the energy-saving melting furnace 1 11 and the energy-saving melting furnace 2 12, and then puts the materials to be smelted into the inner melting furnace 14 respectively, and then closes the two furnace covers 15 to ensure the sealing of the two inner melting furnaces 14 in the energy-saving melting furnace 1 1 and the energy-saving melting furnace 2 12. Then, the staff energizes the heating coil 18 through the external controller, and the heating coil 18 will indirectly heat the two inner melting furnaces 14 after being energized, so as to achieve metal smelting. In the process of heating and smelting, the staff can connect the air supply pipe 17 to the external air supply device, which is a prior art. It can inject inert gas into the inner melting furnace 14 through the air supply pipe 17, and the inert gas can promote the distribution of the composition of the molten metal to be more uniform. Metal smelting can be carried out simultaneously by using two inner melting furnaces 14, and the introduction of inert gas during the smelting process can promote a more uniform distribution of the molten metal components and improve the smelting effect. The two furnace covers 15 are sealed above the energy-saving melting furnace 1 11 and the energy-saving melting furnace 2 12 to reduce the heat loss inside the two, thereby improving the efficiency of metal smelting and reducing smelting energy consumption.

[0022] As an improvement, Figures 1 to 7As shown, a positioning processing mechanism is commonly arranged above the energy-saving melting furnace 11, the energy-saving melting furnace 2, and the vaporization furnace 13. The positioning processing mechanism includes a mounting plate 21 fixedly mounted on the top surface of the vaporization furnace 13, a driving motor 22 is fixedly mounted on the mounting plate 21, two synchronous wheels 23 are fixedly connected to the output shaft below the driving motor 22, two raised columns 24 are rotatably connected to one side of the top surface of the vaporization furnace 13 close to the driving motor 22, and the bottoms of the two raised columns 24 are fixedly connected to synchronous wheels 241, and belts 25 are transmission-connected between the two synchronous wheels 241 and the two synchronous wheels 23. Specifically, the two synchronous wheels 23 are arranged in an upper and lower distribution, one synchronous wheel 241 is transmission-connected to the upper synchronous wheel 23 through a belt 25, and the other synchronous wheel 241 is transmission-connected to the lower synchronous wheel 23 through another belt 25. That is to say, the output shaft of the driving motor 22 rotates, and the two raised columns 24 can be driven to rotate synchronously through the two synchronous wheels 23 and the two belts 25. A perforated plate 26 is fixedly connected to one side of the top surface of the vaporization furnace 13 near the two raised columns 24. A displacement rod 27 is movably inserted on the top of the perforated plate 26. The displacement rod 27 only vertically moves up and down in the limiting hole. Two rectangular strips are symmetrically arranged on the outer ring surface of the displacement rod 27. A limiting hole for the displacement rod 27 to slide up and down is arranged on the top of the perforated plate 26. The lower end of the displacement rod 27 is a hemispherical shape with a smooth surface, and the displacement rod 27 is located on the path of the rotational movement of the raised column 24. The top surface of the raised column 24 is composed of a horizontal surface and an inclined surface. Specifically, the hemispherical part of the lower end of the displacement rod 27 is located on the rotational movement path of the horizontal surface and the inclined surface of the raised column 24. An open plate 28 is fixedly arranged on the top of the displacement rod 27. A spring 1 271 is connected between the outer wall of the displacement rod 27 and the bottom surface of the open plate 28. At the initial stage, the hemispherical part of the lower end of the displacement rod 27 fits with the horizontal surface of the top of the raised column 24, and the spring 1 271 is in a compressed state. The end of the open plate 28 away from the displacement rod 27 is detachably connected to a scraper ring 29, and a circular scraper is provided on the top of the scraper ring 29. The scraper ring 29 and the circular scraper are both made of ceramic material. The circular scraper is used to better scrape off the residue and dust attached to the outer wall of the inner furnace 14. The ceramic material has high hardness, heat resistance and wear resistance, which improves the service life of the scraper ring 29 and the circular scraper. The top surface of the scraper ring 29 is detachably connected to a collecting ring 210.

[0023] Furthermore, if Figure 7As shown, a plug plate 281 is movably inserted inside the open plate 28 near the scraper ring 29, and a spring 282 is connected between the plug plate 281 and the inside of the open plate 28. A matching plate 283 is provided at the position of the scraper ring 29 corresponding to the plug plate 281, and the end of the plug plate 281 away from the open plate 28 is tightly inserted into the matching plate 283. The outer wall of the scraper ring 29 and the collecting ring 210 near each other is fixed with an extension plate, and the two extension plates are fastened by screws and nuts. The scraper ring 29 and the collecting ring 210 are coaxially arranged with the energy-saving furnace 1 11 and the energy-saving furnace 2 12, and the scraper ring 29 can be attached to the outer wall of the energy-saving furnace 1 11 and the energy-saving furnace 2 12.

[0024] When in use: After one smelting is completed, the staff opens the furnace cover 15 above the energy-saving melting furnace 11 and the energy-saving melting furnace 2 12, and can use the existing lifting tools to extract the two inner melting furnaces 14 from the energy-saving melting furnace 11 and the energy-saving melting furnace 2 12, and pour all the molten metal liquid in the two inner melting furnaces 14 into the required container. When the next smelting is required, the two inner melting furnaces 14 are placed in the energy-saving melting furnace 11 and the energy-saving melting furnace 2 12 with the help of the lifting tools. During the placement process, the staff can refer to the positions of the scraper ring 29 and the collecting ring 210, and gradually place the inner furnace 14 downward into the energy-saving furnace 11 and the energy-saving furnace 2 12. During the lowering process, the outer wall of the inner furnace 14 will contact the scraper ring 29, so that the scraper ring 29 can be used as a positioning reference for the inner furnace 14, which is convenient for the inner furnace 14 to be placed into the energy-saving furnace 1 11 and the energy-saving furnace 2 12. At the same time, during the process of lowering the inner furnace 14, the scraper ring 29 can also prevent the inner furnace 14 from tilting and shaking, thereby ensuring the safety of the lowering process of the inner furnace 14.

[0025] At the same time, considering that when the molten metal liquid in the inner melting furnace 14 is poured out, part of the metal liquid will adhere to the outer wall of the inner melting furnace 14 and form metal residues, so in the process of lowering the inner melting furnace 14 to the energy-saving melting furnace 1 11 and the energy-saving melting furnace 2 12, the staff can start the driving motor 22 through the external controller, and drive the two synchronous wheels 1 23 to rotate through the output shaft of the driving motor 22. As the two synchronous wheels 1 23 rotate, the corresponding synchronous wheels 2 241 will be driven to rotate synchronously through the two belts 1 25, thereby driving the corresponding raised column 24 to rotate synchronously. As the raised column 24 rotates, its horizontal surface gradually moves away from the hemispherical part of the lower end of the displacement rod 27. At this time, under the action of the rebound force of the spring 1 271, the displacement rod 27, the open plate 28, the scraper ring 29, and the collecting ring 210 are vertically displaced downward. In the process, the hemispherical part of the lower end of the displacement rod 27 will conflict with the inclined surface of the raised column 24. As the raised column 24 continues to rotate, the hemispherical part at the lower end of the displacement rod 27 will collide with the inclined surface of the raised column 24, and cause the displacement rod 27, the open plate 28, the scraper ring 29, and the collection ring 210 to gradually move upward vertically. During this process, the spring 1 271 will be gradually compressed until the horizontal surface of the raised column 24 again contacts the hemispherical part at the lower end of the displacement rod 27, at which time the spring 1 271 is compressed to the initial state. In this way, as the raised column 24 continues to rotate, the scraper ring 29 and the collection ring 210 can continuously perform vertical reciprocating movements up and down. Therefore, when the inner furnace 14 is placed downwardly into the energy-saving furnace 11 and the energy-saving furnace 2 12, the scraper ring 29 that can reciprocate up and down is used to scrape the outer walls of the energy-saving furnace 11 and the energy-saving furnace 2 12, so that the metal residues attached to the outer walls of the energy-saving furnace 11 and the energy-saving furnace 2 12 are scraped off, and the scraped metal residues will fall into the space between the scraper ring 29 and the collecting ring 210, thereby effectively preventing the metal residues from falling into the energy-saving furnace 11 and the energy-saving furnace 2 12, and reducing the subsequent manual cleaning steps; When heating the energy-saving furnace 11 and the energy-saving furnace 2, the metal residues adhering to the outer wall of the energy-saving furnace 11 and the energy-saving furnace 2, 12 are scraped off to avoid excessive metal residues adhering to the outer wall of the energy-saving furnace 11 and the energy-saving furnace 2, 12, which will affect the heat conduction effect of the two furnaces. This is beneficial for the heating coil 18 to fully heat the energy-saving furnace 11 and the energy-saving furnace 2, 12 to ensure the heating effect, and avoid the heating coil 18 heating the energy-saving furnace 11 and the energy-saving furnace 2, 12, which will be blocked by the metal residues and cause uneven heating. This not only ensures the effect of metal heating and smelting, but also reduces the energy loss during heating by the heating coil 18, thereby improving the energy-saving effect of the furnace.

[0026] Considering that the scraper ring 29 will be worn and damaged after long-term use. When the staff needs to replace the scraper ring 29, they can first separate the screws and nuts between the collection ring 210 and the scraper ring 29, separate the collection ring 210 from the scraper ring 29, and then manually move the plug plate 281 horizontally in the direction away from the matching plate 283, causing the spring 282 to be compressed in the process, until the plug plate 281 is separated from the matching plate 283, and then the scraper ring 29 can be removed for replacement. When installing again, first manually move the plug plate 281 horizontally in the direction close to the spring 282, causing the spring 282 to be compressed, and then match the matching plate 283 with the plug plate 281, and then release the plug plate 281. Under the action of the rebound force of the spring 282, the plug plate 281 is automatically inserted into the matching plate 283 to achieve the reinstallation of the scraper ring 29. Therefore, through the cooperation of the set plug plate 281, the matching plate 283 and other components, after the scraper ring 29 is severely worn or damaged, the staff can easily realize the disassembly and replacement work, thereby improving the convenience of the disassembly and replacement operations. At the same time, by replacing the scraper ring 29, the effectiveness of the scraper ring 29 in scraping off the metal residue attached to the outer wall of the inner furnace 14 is ensured, further preventing the metal residue from falling into the furnace and affecting the smelting effect.

[0027] Embodiment 2: Figure 8 , Fig. 9 As shown, the above-mentioned energy-saving melting furnace for metal smelting also includes a follow-up collection mechanism that is commonly arranged on the vaporization furnace 13 and the protruding column 24 and the collecting ring 210. The follow-up collection mechanism includes a discharge pipe 31 that is connected to one side of the collecting ring 210. The discharge pipe 31 is arranged in an inclined manner. Before use, a collection container can be placed directly below the end of the discharge pipe 31 away from the collecting ring 210. The top surface of the collecting ring 210 is rotatably connected to a gear ring 32, and a push plate 321 is fixedly connected to the inner ring surface of the gear ring 32. The shape of the bottom of the push plate 321 is adapted to the shape between the scraper ring 29 and the collecting ring 210, and the bottom of the push plate 321 is initially in contact with the portion between the scraper ring 29 and the collecting ring 210. A gear column 33 is rotatably connected to the top surface of the vaporizer 13 and one side close to the gear ring 32. The teeth on the gear column 33 mesh with the teeth on the gear ring 32. The teeth on the gear column 33 always mesh with the teeth on the gear ring 32. That is to say, when the collecting ring 210 reciprocates up and down, the teeth on the gear ring 32 also mesh with the teeth on the gear column 33. A synchronous wheel 34 is coaxially fixedly connected to the bottom of the gear column 33, and a synchronous wheel 4 35 is coaxially fixedly connected to the bottom of the protruding column 24. A belt 2 36 is connected between the synchronous wheel 4 35 and the synchronous wheel 3 34.

[0028] During use: At the same time, considering that the inner melting furnace 14 is in use, its outer wall will also be stained with slag ash produced during smelting, and dust from the external environment during the process of pouring molten metal. When the scraper ring 29 in the above embodiment 1 scrapes the outer wall of the inner melting furnace 14, it will also scrape off the dust or particles on the outer wall. The scraped dust or particles will fall into the space between the scraper ring 29 and the collecting ring 210. At the same time, in the process of the output shaft of the driving motor 22 driving the raised column 24 to rotate in the above-mentioned embodiment 1, the raised column 24 will also drive the synchronous wheel four 35 to rotate synchronously, and the synchronous wheel four 35 will drive the synchronous wheel three 34 to rotate synchronously through the belt two 36, thereby prompting the gear column 33 to rotate synchronously, and as the gear column 33 rotates, it will drive the gear ring 32 meshing with it to rotate in the opposite direction, and then drive the push plate 321 to rotate synchronously through the gear ring 32, and the push plate 321 fits the part between the scraper ring 29 and the collection ring 210, so that the push plate 321 will push the dust and particles to move in the space between the scraper ring 29 and the collection ring 210, and when the dust and particles are pushed to the position of the discharge pipe 31, under the action of gravity, the dust and particles will be discharged outward into the collection container.

[0029] Therefore, by setting the cooperation of components such as the gear ring 32 and the push plate 321, when the inner furnace 14 is placed downwardly into the energy-saving furnace 11 and the energy-saving furnace 2 12, the rotation of the push plate 321 can be used to automatically push and discharge the dust and impurities scraped off the outer wall of the inner furnace 14, thereby preventing dust from entering the energy-saving furnace 11 and the energy-saving furnace 2 12 and adhering to the surface of the heating coil 18, thereby avoiding local uneven heating of the heating coil 18, and at the same time ensuring the service life of the heating coil 18 and the stability of the heating coil 18 during the metal smelting process.
