Problems solved by technology

[0002] In the process of smelting lead ore, the lead ore is usually smelted and reduced to obtain crude lead material, and then the crude lead material is electrolyzed in the electrolytic cell to obtain electrolytic lead with high purity and the remaining anode slime with low lead content, anode slime It is a slimy raw material with relatively low lead content. The anode slime smelting furnace is a boiler that purifies the anode slime at high temperature to obtain noble lead with high lead content. The upper part of the traditional anode slime smelting furnace is directly equipped with a feeder , the inlet and outlet of the smelting furnace are a furnace mouth, when feeding, use the crane to hoist the anode slime to the feeding platform, turn the furnace mouth to the feeding position, manually open the feeding handle, and put the anode slime directly into the furnace , the flue gas generated due to the large heat in the furnace is also relatively large during feeding, the feeding time is short, anode slime will accumulate in the furnace in large quantities, and the amount of feeding at one time is small. After 6 hours of reduction smelting, the lower part of the furnace is basically After the melting is completed, the upper material slides down, collapses, and directly enters the melt. The strong airflow forms a large shock wave and impacts outside the furnace, causing environmental pollution. After 10 hours, the precipitation ends and enters the stage of slag and lead discharge. This process has less material input , high cost, polluting the environment and low anode slime smelting, occupying a large amount of inventory

Embodiment 1

[0035] Such as Figure 1~Figure 4 As shown, an anode slime smelting furnace includes a smelting furnace 11 and a belt conveyor 1. The smelting furnace 11 is cylindrical, and a horizontal shaft 10 is installed at the center of the two end faces of the smelting furnace 11. One end of the horizontal shaft 10 is installed at the center of the end face of the smelting furnace 11, the other end of the horizontal shaft 10 is connected to the first bracket 4, and the gap fit between the horizontal shaft 10 and the first bracket 4, the right end face of the smelting furnace 11 The lower part is provided with a burner 12, the side of the smelting furnace 11 is provided with a feed port 2 and a rectangular protrusion 7, the height of the protrusion 7 is equal to the horizontal axis 10, and the top of the protrusion 7 is provided with a long A square discharge port, the discharge port of the protrusion 7 communicates with the inner cavity of the smelting furnace 11, and the distance betwe...

Embodiment 2

[0055] The structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is:

[0056] The angle between belt conveyor 1 and the horizontal plane is 25 o .

[0057] The angle between the side and the bottom surface of the truncated cone at the bottom of the tank body 132 is 35°. o , the ratio of the inner diameter to the height of the discharger 131 is 1:1.2.

[0058] An anode slime smelting furnace, the process steps are:

[0059] h. The first motor 9 and the second motor 5 in front of the smelting furnace 11 drive the smelting furnace 11 to rotate downward for 90 o First emit the scum on the upper layer of the noble lead liquid, then emit the noble lead liquid in the smelting furnace 11, and reserve the noble lead liquid whose volume is 6% of the furnace cavity volume of the smelting furnace 11 in the smelting furnace 11 simultaneously;

[0060] Due to the improvement of the structure and process of t...
