[0004] However, during the actual use of this structure, the staff can only use the dust removal operation inside the silicon carbide smelting furnace at the furnace mouth position, but some silicon carbide smelting dust will be blocked inside and cannot fly out of the furnace mouth, and a comprehensive and thorough cleaning operation cannot be performed. At the same time, the equipment cannot perform rapid stirring and suction operations inside the silicon carbide smelter, and cannot meet the daily efficient dust removal operations of the silicon carbide smelting furnace and cannot meet daily use needs. Therefore, it is urgent to design an efficient dust removal device for the silicon carbide smelting furnace to solve the above problems. Summary of the invention

At the same time, the equipment cannot perform rapid stirring and suction operations inside the silicon carbide smelting furnace, cannot meet the daily high-efficiency dust removal operations of the silicon carbide smelting furnace, and cannot meet the daily use needs.

In actual use, the staff first pours the raw materials to be processed by silicon carbide smelting from the top of the top seat into the interior of the furnace body, and then seals the top seat through the movable shaft and the movable flap. At this time, the interior of the furnace body can be cleaned during the silicon carbide smelting process. The silicon carbide raw material inside the furnace body is sucked and tumbled up and down through the upper flow seat and the lower flow seat. The silicon carbide raw material is evenly and quickly tumbled up and down from the flow side seat and the connecting valve seat through the connecting grooves at the four corners of the sides of the upper flow seat and the lower flow seat in conjunction with the material leveling grid on the inner wall. Then the silicon carbide raw material inside the flow side seat can be quickly sucked and flowed inside the flow suction pipe. At the same time, the first dust removal hole groove on the side of the flow suction pipe can enable each part of the silicon carbide raw material to undergo targeted and efficient dust removal operations for silicon carbide smelting, which reflects the practicality of the equipment design.

[0015] The high-efficiency dust removal device for the silicon carbide smelting furnace further improves the overall use effect of the equipment by arranging the furnace body, dust collector base, top base, pumping trough, collecting frame, rotating base, stirring blades and second dust removal hole grooves. In daily use, when the silicon carbide smelting raw materials are smelted inside the furnace body, the rotating base in the center of the furnace body can be started to drive the stirring blades on the side to rotate synchronously, thereby achieving full stirring of the silicon carbide raw materials inside the furnace body. In the stirring process, the dust raised inside the silicon carbide raw materials can be properly and fully absorbed through the rotating base and the second dust removal hole grooves on the sides of the stirring blades. At the same time, the dust absorbed and removed by the flowing side seat and the furnace body can enter the collecting frame inside the pumping trough through the dust collector base for unified collection and then unified processing, which reflects the comprehensiveness of the equipment design.
