Embodiment Construction

[0033] In the drawings, the same reference numerals are used to designate the same or operationally equivalent parts.

[0034] Figures 1 to 3 Apparatus 100 for recycling batteries is shown, which is specifically but not exclusively for recycling Figure 11 A battery 10 of the type shown in the device comprises: an outer casing 20 made of a low molecular weight plastic material (i.e., polypropylene); a plurality of lead alloy-based plates and electrodes 30, 40; lead oxide powder-based a paste or active material; a plurality of separator plates 50 made of a high molecular weight plastic material (such as PET and / or PVC); and an electrolyte comprising a sulfuric acid solution (for lead-acid batteries).

[0035] Specific reference image 3 , said plant comprises at least a battery crushing device 301 and a plurality of devices 401-701 for separating and recovering different parts of the treated batteries, which will be described in detail later.

Abstract

The present invention relates to a plant (100) for the recovery of spent electric batteries, comprising an apparatus (301;301') for crushing said batteries and one or more apparatuses (401-701;401'-601) for separating and recovering the different components of said batteries (metallic grids and poles, low molecular weight plastic materials, high molecular weight plastic materials, paste, electrolyte), said apparatuses (301,401-701;30r,401'-601) being advantageously carried on a mobile unit, such as a semi-trailer (101;101'); said plant can further comprise an apparatus (801;801') for loading said spent batteries to said crushing apparatus (301;301'), said loading apparatus being carried on a second mobile unit, such as a second semi-trailer (201;201').

Description

technical field [0001] The invention relates to a device for recycling waste batteries. [0002] More specifically, but not limited thereto, the present invention relates to a device for recycling so-called lead-acid batteries. Background technique [0003] A lead-acid battery is a type of electrochemical accumulator through which an electric current flows in one direction and then in the opposite direction by means of successive oxidation-reduction reactions. [0004] Figure 11 A lead-acid battery 10 is shown in FIG. The accumulator includes an anode 30 and a cathode 40, which include a lead alloy (for example, lead-antimony alloy) plate that is coated with an oxygen-based paste lead powder (or active material) on the surface, and is immersed in an electrolytic solution through The separators 60 are separated from each other by insulating materials, the electrolyte being a solution containing sulfuric acid, and the insulating materials being high molecular weight plastic...
