The four corners of the mounting plate 23 are all threadedly connected with fixing bolts 32.

[0026] Working principle: the user first puts the crude lead into the melting barrel 3 from the feeding pipe 13, heats the melting barrel 3 through the heating block 4 to melt the crude lead, and then puts additives such as CaO, ZnO or Sb2O3 from the additive placement tube 14, and drives the motor 5 to rotate the rotating rod 7 through the main shaft 6, so that the stirring blades 1 8, 2 9 and 3 10 force the crude lead and the additive to mix. Among them, the structures in the melting barrel 3 are all high temperature resistant and anti-corrosion structures. At the same time, the heat dissipation fan 18 discharges the heat in the melting barrel 3 to the outside of the shell 1 through the connecting pipe 20 and the mounting pipe 19, thereby improving the heat dissipation of the shell 1. Protection allows the molten lead to cool quickly, thereby reducing the oxidation of lead, and finally, it is discharged from the housing 1 from the discharge pipe 12 through the vane pump 11; when disassembling the heat dissipation fan 18, the user first removes the connecting pipe 20 from the mounting flange 22 by opening the movable buckle door 35, and then rotates the fixing bolt 32 off the surface of the mounting plate 23, and then moves the chassis 17 to the outside to make the mounting plate 23 disengage from the mounting groove 15. When the mounting tube 19 moves, the limiting clamping block 27 moves toward the inside of the movable groove 25 in the limiting block 16, and the reset spring 31 contracts, thereby removing the heat dissipation fan 18 from one side of the housing 1.

[0027] In summary: the crude lead pyrometallurgical refining device, by adding stirring blades 1 8, stirring blades 2 9, stirring blades 3 10 and additive placement tubes 14 in the melting barrel, can make the crude lead and additives fully mixed during the melting process, thereby improving the efficiency of removing harmful elements. The realization of this effect is due to the design of the stirring blades, which can force the crude lead and additives (such as CaO, ZnO or Sb2O3, etc.) to mix during the melting process, thereby increasing the contact area between the two, accelerating the reaction speed, and improving the removal efficiency of harmful elements. At the same time, a detachable heat dissipation structure is provided to accelerate the cooling speed and reduce the oxidation of lead. The realization of this effect is due to the heat dissipation structure on the device, which can make the molten lead liquid cool quickly, thereby reducing the oxidation of lead and improving the quality of lead products; in summary, by adding stirring blades and additive placement tubes 14 in the melting barrel, and at the same time providing a detachable heat dissipation structure, the efficiency and quality of crude lead pyrometallurgical refining can be achieved, the quality and purity of lead products can be improved, the cooling speed can be accelerated, and the oxidation of lead can be reduced.
