Described lead powder manufacturing equipment and grid Casting Equipment are connected with the second purifier pipeline with the first purifier respectively;
The production equipment of described lead acid accumulator comprises: the pole plate manufacturing installation described lead powder and new grid being prepared into pole plate, pole plate is carried out assemble the apparatus for assembling forming pole plate group, described pole plate is assembled into plastic casing becomes semi-finished product storage battery assembling device through assemble welding, the acid filling device of dilute sulfuric acid is poured in semi-finished product storage battery, and to the formation device that the semi-finished product storage battery pouring into dilute sulfuric acid changes into.
Below enumerate a specific embodiment and the manufacture method of lead acid accumulator of the present invention and manufacturing system are done more detailed explanation, as shown in Figure 2, the manufacture method of lead acid accumulator, comprising:
After refuse battery returns factory, refuse battery is carried out to drop sulfuric acid, removes the process of copper electrode, carry out cracking and sorting again, oversize is plastics and useless grid, screenings is plumbous mud, respectively oversize and screenings are processed again: oversize isolates useless grid by aqueous medium sorting, useless grid through smelting, refining goes forward side by side the adjustment of metallic element proportioning in quadrat liquid, prepares new grid by rolling and casting mode; The plumbous mud of screenings is through smelting and being prepared into pure plumbous liquid after refining, then through Ba Dunfa, namely vapour phase oxidation process prepares lead powder.Prepare pole plate by the lead powder that formed and new grid, then pass through conventional lead-acid storage battery production technique, as assembling, acid filling, change into, the operation such as arrangement prepares new lead acid accumulator.Battery after qualified on inspection dispatches from the factory and is transported to user and locates to use, and when battery arrives useful life or the time of going wrong carries out battery recycling, then transports refuse battery and returns station-service in the raw material of new battery.
In embodiments of the present invention, the process of lead-acid accumulator and the concentration of production of new lead acid accumulator are in a factory, achieve the industrial chain of lead acid accumulator complete alternation, namely realize the circulation industrial chain from " battery production → sale → recovery → process → raw materials for production → new product battery production ".Utilize refuse battery to produce qualified alloy lead liquid and pure plumbous liquid is respectively used to the grid of new battery and the making of lead powder, avoid the energy waste that secondary molten lead causes, improve the production efficiency of battery, reduce production cost.The air line distance that new production line for manufacturing battery and innoxious refuse battery process line are separated by is no more than 50 meters, reduces floor space; Adopt the rate of recycling used batteries of the method to reach more than 98%, the purity of the pure lead obtained is 99.985%; Recycle used batteries site and new battery commercial networks use, erection staff and refuse battery recall troop and use, and load and unload battery carries out simultaneously, therefore, reduce cost recovery, decrease firing rate and mechanical loss, can reduce carbon emission.
Because whole industrial chain is arranged on a closed plant area, environmental improvement means and facility can be considered, adopt advanced facility, effectively pre-acid-mist, lead dust and other flue dust to the pollution of environment, and are conducive to the technology application carrying out complete series harmlessness disposing and cleaner production.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
