Copper still maintain solid-state, while the density of copper bar is less than metal, can swim on the metal liquid of fusing；According to heating
The retention time of the difference of method, heating can adjust.
2) it detaches：Copper bar and the metal liquid of melting are detached；The metal liquid after melting is swum in due to copper bar, it can be with
Copper bar is taken out from metal liquid.
3) metal liquid recycles：After metal liquid is carried out slag hitting filtering using strainer, the material as anode plate manufacture
It re-uses；Anode plate hangers will produce lead oxide and absorption manganese slag in use, and density is less than metal liquid, swims in
Above metal liquid, dregs are subjected to slag hitting filtering using strainer, leave the system that pure metal liquid is reused for anode plate
Producing material material.
4) copper bar recycles：
A) shaping：Copper bar is shaped as shape workable for anode plate hangers；Anode plate hangers is electrolysed in pyroprocess, meeting
It generates flexural deformation and copper bar is shaped as by shape workable for anode plate hangers by shaping.
B) pickling：Copper bar after shaping is immersed in pickle and carries out pickling；For copper bar in high-temperature heating, surface can be by oxygen
Change, its electric conductivity is reduced, by pickling, by the oxide removal on copper bar surface.
C) tin is scalded：Copper bar after pickling is put into tin liquor and scald tin processing, then anode plate hangers is used as to manufacture material
Material stores for future use.Copper bar after pickling is immediately placed in tin liquor carry out scald tin processing, make copper bar surface adhere to tin, to copper bar into
Row protection, keeps copper bar surface not oxidized, improves the electric conductivity of copper bar.Copper bar after boiling hot tin manufactures standby as anode plate hangers
It is stored with material.
Preferably, heated described in step 1), including：Carbon heating and electromagnetic heating method.Carbon heating, i.e., by waste and old sun
Pole plate hangers is placed in the pot of carbon heating, and preset certain metal liquid in pot adds the waste and old anode plate hangers in pot
Heat.Preset certain metal liquid is conducive to the fusing of metal, improves smelting efficiency.

Body, pot body have heat insulation function, are used for the collection of molten Pb liquid, when being powered to electromagnetic coil, the waste and old hangers in coil
It is heated, the metal liquid of fusing is fallen into pot body.The aperture of electromagnetic coil is set as 20cm or more, can be simultaneously to multiple waste and old
Hangers is heated.When being heated using electromagnetic coil, heating time is shorter, and compared with carbon heating, the efficiency of heating surface is high, and
It economizes on resources, reduces environmental pollution.
Preferably, the aperture of strainer described in step 3) is 1~5mm.
Preferably, the pickle that uses of step 4) pickling for：The hydrochloric acid or sulfuric acid of concentration 5%~20% and hydrogen peroxide
Mixed liquor；Wherein, a concentration of the 5%~20% of sulfuric acid, a concentration of with 27.5%, the mixing ratio of sulfuric acid and hydrogen peroxide of hydrogen peroxide
Example is 9：1；Pickling temperature is 40~60 DEG C, and the immersion time is 1~3min.
