Description
Technical field
The present invention relates to a kind of method that lead-acid accumulator cast welding lead skim is reclaimed.
Background technology
In present lead-acid storage battery production, pole plate will be through stages such as coated plate, pouring acid solidifications.Pass through brush version and cast panel in pole plate
Stage, it will produce more cast welding scrap lead slag.The lead skim is part bulky grain metal solid, part lead powder dirt.Existing
Lead-acid storage battery production industry, due to can not voluntarily be handled.It will uniformly be collected, be sold to lead returned enterprise, no
Production cost is increase only, and adds environmental pressure.But lead-acid accumulator is in process of production, technology controlling and process is strict,
The characteristics of this has also achieved the stable homogeneous of the cast welding lead skim produced.The bulky grain lead containing major part is closed in cast welding lead skim
Main component is lead oxide, lead sulfate, elementary lead and minimal amount of moisture in gold and powder, powder, also containing minimal amount of lead
Acid accumulator is formulated.Each component content is basically stable within the scope of one, therefore utilizes the stability and collimation of cast welding lead skim
The characteristics of, recycled, be directly appended in lead-acid accumulator.
The existing recovery to cast welding lead skim, substantially using the pyrometallurgical recovery methods of existing scrap lead cream, i.e., passes through cast welding lead skim
High melt is crossed, point solution obtains being electrolysed lead bullion.This method not only needs higher temperature to carry out melting, and is to occur in melting
Substantial amounts of lead dust and lead skim.It is big for environment pollution, produce the discharge of substantial amounts of point solution waste water.This original consumed with existing drop this section
Then want to run counter to.Cast welding lead skim can not be subjected to processing utilization for lead-acid accumulator factory, the outer lead of selling to that can only be packed is smelted
Producer, not only reduces the profit of lead-acid accumulator, and increases pollution of the whole lead-acid accumulator to environment.To cast-on lead
Slag is simply handled, and is recycled, and will be huge opportunity for whole lead-acid accumulator.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of method that lead-acid accumulator cast welding lead skim is reclaimed, bag
Following steps are included, step 1, the cast welding lead skim being collected into is added in vibratory sieve, bulky grain lead skim and lead dust are separated, and respectively
It is placed in clean bag, waits pending；Step 2, graininess lead skim and lead dust are used into certain density dipping by lye one respectively
After the section time, separation of solid and liquid；Step 3, cleaned by the lead skim and lead dust that are obtained in step 2 using pure water；Step 4, in step 3
Lead skim is added to vacuum lead melting furnace, low smelting heat, and double teeming is into cast welding leads, and the lead dust in step 3 is added directly into lead acid storage battery
In the paste mixing machine in pond.
Further, in the step 1, the sieve mesh number that vibratory sieve is used is more than 400 mesh.
Further, in step 2, the percent mass concentration of the alkali lye of addition is 1-10%.
Further, the desulfurization of the lead dust is shearing desulfurization, stirring desulphurization or ball milling desulfurization.
Further, the desulfurization of the graininess lead skim is stirring desulphurization or immersion desulfurization.
Further, the desulfurization time of the alkali lye is 5-20min, and the desulfurization temperature of the alkali lye is 20-40 DEG C.
Further, the lead skim and lead dust in the step 3 are cleaned using pure water, and PH is 7-9.
Further, in step 4, low smelting heat temperature is 300-400 DEG C.
The method that lead-acid accumulator cast welding lead skim of the present invention is reclaimed, reduces the production cost of lead-acid accumulator, reduces
The discharge of lead discarded object, energy-conserving and environment-protective.
