The 3rd step: all electrolyte through being provided with the dicang bottom surface of constant slope, is pooled in the liquid collecting hole of dicang lowest part, through submerged pump electrolyte is delivered in the filter and filters,
The 4th step: filtrate is delivered to primary lead through the electrolyte delivery pump produce the diluted acid of acid making system and store in the medial launder, add to the industrial sulphuric acid that manufactures a finished product in the acid making system according to the needs of relieving haperacidity.
All and the contacted part of electrolyte all are to be made of anticorrosion acidproof material material.
Described hydraulic grab is the grab buckets of hydraulic pressure six lobes, grab bucket of hydraulic pressure six lobes and charging belt machine liquid dish all are stainless steels, dicang and liquid collecting hole are acidproof granite materials, and described filter is a filter press, and it all is acidproof materials that filter press, various pump, diluted acid store medial launder.
The described dicang bottom surface that is provided with constant slope is the gradient with 0.5% ∽ 5%.
Described filtrate is not for containing the dilution heat of sulfuric acid of solid impurity.
In step 4, earlier filtrate is sent in the diluted acid storage tank, again with filtrate through the electrolyte delivery pump is transported to diluted acid intermediate storage groove in the primary lead factory acid making system by the PO pipeline in, add to the industrial sulphuric acid that manufactures a finished product in the acid making system according to the needs of acid making system in good time; The PO pipeline is the pipeline that connects new-old system, also diluted acid storage medial launder and Sewage Disposal in the old system are coupled together simultaneously, be located on the diluted acid intermediate storage groove in the acid making system temporarily to the Sewage Disposal floss hole, at acid making system fail-open is arranged, diluted acid is discharged into Sewage Disposal handles.
The present invention has following good effect:
1, battery electrolyte solution is made full use of, make industrial sulphuric acid again, the real realization turned waste into wealth;
2, avoided the pollution of electrolyte solution, huge environmental benefit and social benefit have been arranged environment;
3, because waste and old electrolyte has replaced the industrial moisturizing in the sulfate system, saved water resources;
4, successfully the grab bucket of hydraulic pressure six lobes is referred to used and scrapped battery and reclaim in the pretreatment system, the electrolyte solution in the process discharging storage battery of the stirring of utilization grab bucket and batch turning; Reduced the equipment of putting acid specially;
5, the Sewage Disposal to the primary lead system is reserved with floss hole in this device, when as the primary lead acid making system fault being arranged, electrolyte can be discharged into Sewage Disposal temporarily handle, and electrolyte is to the pollution of environment when having avoided accident condition;
