Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multifunctional melting furnaces, in particular to a novel multifunctional melting furnace. Background Art
[0002] Melting furnace, also known as crucible furnace, is the simplest smelting equipment, mainly used to melt non-ferrous metals with low melting points, such as copper, aluminum and their alloys. In this furnace, the alloy is melted in the crucible, and the heat is transferred to the charge through the crucible. The charge and the combustion products are not in direct contact, so the chemical composition of the alloy is almost unaffected by the furnace gas, and the temperature of the alloy liquid is also relatively uniform, which is its main advantage.
[0003] Through patent search, it was found that a new type of multifunctional melting furnace with publication number CN211291024U is provided with a lifting mechanism, and the lifting mechanism can drive the sealing cover and the stirring mechanism to rise and fall, so that raw materials can be added to the inside of the crucible, and the solution inside the crucible can also be poured out by the second servo motor. However, its lifting mechanism is installed on the top of the crucible, which causes the overall center of gravity of the crucible to shift. During operation, the crucible may shake due to the shift of the center of gravity, causing part of the internal high-temperature molten liquid to flow to the gap between the bottom of the sealing cover and the contact between the sealing cover and the crucible. Part of the molten liquid cannot be heated and cooled, and will fill the gap between the sealing cover and the crucible, causing the sealing cover to be stuck and unable to be separated from the crucible body. For this reason, we propose a new type of multifunctional melting furnace to solve or improve the above problems. Utility Model Content

[0010] Furthermore, a high temperature resistant sealing gasket slightly smaller than the inner diameter of the crucible is arranged at the bottom of the sealing cover.
[0011] Compared with the prior art, the utility model has the following beneficial effects: by arranging a support column, a hollow stud, a second motor and a threaded rod, the hollow stud can be driven to rotate by the second motor when the crucible needs to be sealed and stirred, so that the hollow stud drives the threaded rod connected by the thread to move, thereby driving the sealing cover to move and making the bottom of the sealing cover contact with the top of the crucible, thereby sealing the inside of the crucible; because the support column is fixed to the surface of the crucible and when the crucible is sealed, the limit rod and the threaded rod are both inside the support column, and the second motor is located at the bottom of the support column, it will not cause the center of gravity of the crucible to shift, so the crucible will not shake due to the shift of the center of gravity, thereby avoiding the high-temperature molten liquid from flowing into the gap at the bottom of the sealing cover and the contact between the sealing cover and the crucible due to shaking, causing part of the molten liquid to be unable to be heated and then fill the gap between the sealing cover and the crucible after cooling, causing the sealing cover to be stuck and unable to be separated from the crucible body.

The fourth motor 10 can drive the rotating shaft fixed at the top of the output shaft to rotate. When the rotating shaft rotates, it will drive the fixed sealing cover 8 to rotate. A high-temperature resistant sealing gasket slightly smaller than the inner diameter of the crucible 2 is provided at the bottom of the sealing cover 8. The high-temperature resistant sealing gasket can seal the gap between the top of the crucible 2 and the inner wall of the sealing cover 8.

[0020] Working principle: when the melting furnace needs to be used, the second motor 5 drives the hollow stud 14 to rotate, so that the hollow stud 14 drives the threaded rod 6 to move, so that the threaded rod 6 drives the sealing cover 8 to move upward through the fixed block fixed on the top, and the limit rod 7 can assist the threaded rod 6 in pushing the movement of the fixed block, so that the rise and fall of the threaded rod 6 are relatively stable, reducing or avoiding the shaking phenomenon during the movement of the fixed block and the sealing cover 8. When the sealing cover 8 is raised, the metal block to be melted can be placed inside the crucible 2. When the metal block is placed, the second motor 5 is reversed to make the sealing cover 8 The crucible 2 is sealed by the third motor 9, and the crucible 2 can be heated at this time. During the heating process, the stirring column 12 can be driven to rotate by the third motor 9, so that the stirring column 12 drives the stirring rod 13, the second scraper 15 and the first scraper 11 to rotate. When the stirring rod 13 rotates, the melted metal melt or the semi-melted solid-liquid mixed melt in the crucible 2 can be stirred to make the melt heated more evenly. The first scraper 11 can scrape the high-temperature solution on the inner wall of the crucible 2 to fully merge it with the relatively low-temperature solution near the center of the crucible 2. When the second scraper 15 rotates, The solid metal deposited on the bottom of the crucible 2 is scraped and stirred to make it heated more evenly and accelerate its melting speed. At the same time, when the crucible 2 is in a sealed state, because the support column 4 is fixed to the surface of the crucible 2 and when the crucible 2 is sealed, the limit rod 7 and the threaded rod 6 are both inside the support column 4, and the second motor 5 is located at the bottom of the support column 4, the center of gravity of the crucible 2 will not be shifted, so the crucible 2 will not shake due to the shift of the center of gravity, thereby avoiding the high-temperature molten liquid from flowing to the gap between the bottom of the sealing cover 8 and the contact between the sealing cover 8 and the crucible 2 due to shaking, causing part of the molten liquid to be unable to be heated and cooled After that, the gap between the sealing cover 8 and the crucible 2 will be filled, causing the sealing cover 8 to be stuck and unable to be separated from the main body of the crucible 2. When the metal inside the crucible 2 is completely melted into liquid, the second motor 5 drives the hollow stud 14 to rotate, so that the hollow stud 14 drives the threaded rod 6 to move, and the threaded rod 6 drives the sealing cover 8 to move upward through the fixed block fixed on the top, so that the sealing cover 8 is separated from the sealed state with the crucible 2. At this time, the first motor 3 drives the support column 4 to rotate, so that the support column 4 drives the fixed crucible 2 to rotate, so that the molten liquid inside the crucible 2 can be poured out, completing the metal melting process.
