Embodiment Construction

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

[0034] Figures 1 to 3 show an apparatus 100 for recycling batteries, which is particularly, but not exclusively, used for recycling batteries 10 of the type shown in Figure 11, the apparatus includes: an outer casing 20 made of a low molecular weight plastic material ( That is, polypropylene); a plurality of lead alloy-based plates and electrodes 30, 40; a paste or active material based on lead oxide powder; a plurality of separator plates 50, which are made of high-molecular-weight plastic materials (such as PET and / Or PVC); and an electrolyte containing a sulfuric acid solution (for lead-acid batteries).

[0035] 3, the equipment includes at least a battery crushing device 301 and a plurality of devices 401-701 for separating and recovering different parts of the processed battery. These devices will be described in detail later.

[0036] According to the presen...

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 to this, the present invention relates to a device for recycling so-called lead-acid batteries. Background technique [0003] A lead-acid battery is an electrochemical accumulator type battery in which current generated by successive oxidation-reduction reactions flows through the electrochemical accumulator in one direction and then in the direction opposite to that direction. [0004] The lead-acid battery 10 is shown in FIG. 11. The accumulator includes an anode 30 and a cathode 40, which include an electrode plate made of a lead alloy (for example, a lead-antimony alloy) coated with an oxygen-based paste-like lead powder (or active material) on the surface, and immersed in an electrolyte, through Separating plates 60 made of insulating materials are separated from each other, the electrolyte is a solution containing sulfuric acid, and the insulat...
