Silicon carbide is a semiconductor that exists in nature in the form of the extremely rare mineral moissanite. Smelting is a refining technology that refers to the use of roasting, smelting, electrolysis and chemical agents to extract metals from ores, reduce impurities in metals or increase certain components in metals, and refine them into the required metal.

[0003] For example, the patent document with the announcement number CN 219301331 U discloses a carburizing structure for a silicon carbide smelting furnace, a carburizing structure for a silicon carbide smelting furnace, comprising a furnace body, the upper end face of the furnace body is open, a furnace cover is slidably connected to the furnace body, and is used to cover the upper end face opening of the furnace body, the furnace body is provided with a driving device for controlling the sliding of the furnace cover, the baffle is provided with a limit assembly that cooperates with the furnace cover to limit the sliding of the shielding assembly, the telescopic end of the electric telescopic rod can be controlled to be extended and retracted by a controller, so as to control the furnace cover to cover or separate the upper end face opening of the furnace body, the baffle is adjusted according to the working environment and the internal smelting conditions, when the baffle completely covers the through slot, the interior of the furnace body is closed, when the baffle partially covers the through slot or the position of the baffle and the through slot are completely misaligned, the gas inside the furnace body is discharged to the outside of the furnace body through the through slot.

[0004] However, when this structure is used for silicon carbide smelting, it is unable to properly remove the tiny detached debris generated by the smelting of raw materials, resulting in a large amount of debris leakage when the silicon carbide finished product is subsequently taken out. At the same time, the equipment is unable to perform efficient and continuous dust removal operations for silicon carbide smelting. Finally, the debris and dust generated by cleaning cannot be properly recycled and cannot meet daily use needs. Therefore, it is urgent to design a silicon carbide smelting furnace with a leakage-proof structure to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a silicon carbide smelting furnace with a leakage-proof structure to solve the problem that the existing structure proposed in the above background technology is unable to properly remove the fine debris generated by the smelting of raw materials when used for silicon carbide smelting, resulting in a large amount of debris leakage when the silicon carbide finished product is subsequently taken out, and the equipment is unable to perform efficient and continuous dust removal operations for silicon carbide smelting, and the debris and dust generated by the final cleaning cannot be properly recycled and cannot meet the daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a silicon carbide smelting furnace with a leakage-proof structure, comprising a furnace body, an air guide cover is arranged inside the furnace body, a sleeve frame is arranged inside the air guide cover, a material loading rack is movably connected inside the sleeve frame, and a top cover is movably connected to the top of the furnace body;

[0011] Preferably, an air suction ring net is arranged at the inner edge of the top cover, and an air suction frame is arranged at the inner center of the top cover.

[0012] Preferably, a partition grid is fixedly connected to the bottom end of the material carrier, and discharge interfaces are arranged on the four sides of the partition grid.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

In actual use, the staff first puts the silicon carbide smelting raw materials into the loading rack, and then stacks the loading racks and installs them inside the socket frame. At this time, the silicon carbide smelting operation is performed inside the socket frame of the furnace body. During the smelting process, the vibration unit inside the connecting base is started, and vibration and knocking operations can be performed from the bottom of all loading racks to vibrate and fall off the fine debris generated by the silicon carbide smelting inside the loading rack. Then, the material enters the material guide pipes on the four sides of the socket frame from the discharge interface of the partition grid frame at the bottom of the loading rack, and is transported along the material guide pipe to the inside of the connecting base and the receiving rack. Finally, the material storage operation is performed in the storage liner to avoid leakage problems, which reflects the practicality of the equipment design.

[0015] The silicon carbide smelting furnace with a leakage-proof structure further improves the overall use effect of the equipment through the top cover, material receiving rack, vibrating unit, dust collecting cloth cover, material storage liner, discharge valve seat, dust exhaust valve seat, material guide pipe, dust exhaust net slot, suction ring net and suction rack. In daily use, the staff can simultaneously start the top cover and the fan assembly inside the material receiving rack to inhale air from the suction ring net on the surface of the top cover and continuously exhaust air from the dust collecting cloth cover on the side of the material receiving rack, thereby forming a rapid vortex airflow from top to bottom inside the furnace body. The airflow inside the furnace body can quickly suck out the debris generated by the silicon carbide smelting inside the loading rack from the dust exhaust net slot of the air guide cover. At the same time, all the airflow and debris can be properly stored inside the material receiving rack and are discharged and collected separately through the discharge valve seat and the dust exhaust valve seat, which reflects the comprehensiveness of the equipment design.
