DE19500001A1 - Unit for destruction of car batteries - Google Patents

Abstract

In an arrangement for destruction of car and engine batteries, the battery is put (1) into a container in which a standard shredder (2) operates acid being collected in a vessel while broken material is conveyed (3) into a washing tank (4) and then to a water column separator (5). The unit can be transported to site for treating batteries.

Description

The invention relates to the creation and the placement of small system modules in conventional containers for mobile or stationary dismantling of car and engine batteries according to the main claim of the claim.

So far, car and engine batteries have had to be stationary be dismantled and processed in lead smelters.

For this purpose, the old batteries usually have to certain collection and delivery points temporarily will. Because the accumulators from the previous owners The batteries are considered old and useless mostly broken and are destroyed with the housing Delivery points are delivered, or are thrown into the Storage container broken. This causes acid to escape and the old batteries must therefore be in acid-proof steel containers are temporarily stored outdoors.

For further transport to the actual metal recycling operations, these storage containers are once again in the heavy V2A transport container poured over.

These transfers and storage conditions arise Risk of injury and polluting emissions in high dimensions. The wholesalers collect the accumulators again until a larger lorry trailer to the Lead huts can be fully loaded.

Since the batteries are transported unassembled, reduce them Acid and housing content, as well as the heavy transport unnecessarily contain the actual recycling share: - The lead in solid and pasty form. -

Therefore the trucks have to be underutilized because of high loads Transport empty weight, more often than necessary the long way take to the lead huts. The resulting increased accident danger and require the unnecessarily traveled distances a rethink in the cutting area.  

This rethinking requires one at the delivery points erectable small system for dismantling the batteries in place. Since the delivery to the Collection points are often only designed in small quantities and a permanently installed small system is therefore not profitable the small mobile system could then work for Use until the stored quantity pays off.

Definitely at the middleman this facility should be installed to load the transport truck in the To be able to raise the lead hut.

The system, stationary or transportable, separates the fixed ones and the liquid battery components in plastic parts, Lead in solid and pasty form with simultaneous Neutralization of the volatile acid components. The main part the acid is collected during the separation process and also recycled.

How the system works

The delivered battery is inserted into the filling opening ( Fig. A1). A conventional shredder or a suitable crushing plant made of acid-proof steel works in container (A2).

The escaping acid is drawn off and in one suitable storage container collected. With the addition of Water and quicklime, that of one Conveyor belt (A3) in the washing tub (A4) conveyed Fraction washed and the still adhering acid from the parts removed and neutralized. Because this sewage Is pH neutral, it can be separated after the solid and pasty lead components and the plastic components without Difficulty in the sewage treatment plant.

The proportions of the batteries are conventional Water column systems (A5) processed and according to the known Floating and sinking processes separately on individual floors (A6) skimmed off. The plastic can because of specific weight can be separated by type.

The paste-like portion of lead is pressed in portions and freed of excess water, collected.

The solid lead components are drained in drip pans and stored. Then under pressure (A7) in transport containers spent and collected for transportation. (A8)  

Since the lead components are now without acid components, these parts, separated into solid and pasty parts, inexpensive and profitable without expensive V2A tubs be transported to the lead huts. There are none Warehouse emissions and in the event of a traffic accident no special protective measures by the auxiliary staff to be required.

The plastics separated in the plant are now still cleaned once and crushed again if necessary. Because the battery case is made of very high quality Plastics are made, arises when this is accepted Leftovers a great demand for reuse.

The captured acid becomes a specific one Cleaning again in the cycle of use come. This saves resources and the Saving effects in the raw material cycle generate quickly a high degree of amortization of the system.

To the downtime of the system in the repair and To be able to keep maintenance down to a minimum is all important Parts of the system created in modular design. A return The defective modules also produce a low one Amount of repair costs and a long use of the individual components.

The wastewater to be discharged into the sewage treatment plants is in collected in a collecting container, again Separation plants and paper filters cleaned and after automated PH adjustment by usual methods released into the sewage system. Here special attention is paid to the high environmental compatibility of the system.

This aspect comes through in conventional lead plants the residue combustion used there is still too short.

Now that all parts of the batteries are largely one are available for further use, one can old conventional battery, until the emergence of gentle alternative developments, without bad Use your conscience.
