[0002] A metal smelting furnace is a piece of equipment designed to refine ore or waste into metal. Different types of smelting furnaces are usually used for different types of metals, such as iron, copper, aluminum, etc. Common types of smelting furnaces include blast furnaces, electric arc furnaces, ladle furnaces, aluminum electrolytic cells, and molten salt smelting furnaces. Depending on the type of metal and specific process requirements, other types of furnaces or specific smelting equipment may also be required. When choosing a smelting furnace, it is necessary to fully consider factors such as raw material characteristics, energy consumption, and environmental impact to ensure that the most suitable smelting equipment is selected.

[0003] The metal smelting furnaces currently on the market still have the following shortcomings: 1. When the existing metal smelting furnace is unloading, part of the slag will adhere to the bottom of the inner cavity of the metallurgical furnace and adhere to it. It is necessary to use a tool to knock it out, which is quite laborious. 2. The existing metal smelting furnace requires manual removal of the furnace cover each time material is added, which is troublesome and poses safety issues.

[0004] 3. Exhaust gas generated by existing metal smelting furnaces is generally discharged directly, but due to the high temperature of waste heat of the exhaust gas, direct discharge causes waste of resources, and the exhaust gas is discharged into the atmosphere, and due to the excessively high temperature of the exhaust gas, it will cause the outdoor temperature to rise.

[0052] Furthermore, in this embodiment, the movable end of the telescopic rod 601 passes through the box body 602 and is fixedly connected to the top of the connecting plate 617, and the connecting plate 617 is driven to move up and down by the telescopic rod 601.

[0053] Specifically, during use, when the flue gas enters the interior of the conveying and collecting box 622 through the air intake pipe 623, the two motors 613 are turned on at the same time to drive the driving rod 612 and the transmission rod 610 to rotate, so that the driving gear 609 drives the driven gear 608 and the rotating column 607 to rotate, so that the transmission belt 605 is transmitted, and the transmission belt 605 drives the toggle plate 606 to move, which can accelerate the flow and mixing of the flue gas, so that the flue gas maintains a relatively uniform temperature in the conveying and collecting box 622, thereby solving the problem of large temperature differences of the flue gas that constantly enters the conveying and collecting box 622, thereby making the subsequent waste heat recovery effect better.

[0054] When the diversion and mixing range between the two sets of concave shells 604 needs to be changed, the telescopic rod 601 is started to drive the two pry bars 614 to rotate upward or downward at the same time. When the two pry bars 614 rotate upward at the same time, the range becomes larger, and when the two pry bars 614 rotate downward at the same time, the range becomes smaller.

[0055] It should be pointed out that the moving directions of the moving plates 606 are all arranged in the same direction of air intake, so as to guide the flow and accelerate the fluidity of the smoke.

[0056] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.

[0057] It should be noted that although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures, equivalent processes or equivalent functional transformations made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
