Abstract

The invention discloses a processing method for recycling waste lead storage batteries, which is characterized in that it comprises the following steps: step S1, crushing and screening, step S2, reusing coarse solid materials, step S3, processing lead paste, step S4, lead Preparation of paste particles, step S5, preparation of rough lead. The processing method for recycling waste lead-acid batteries disclosed by the present invention is simple and easy to operate, has high recycling efficiency and good effect, can efficiently, quickly and safely recycle waste and old lead-acid batteries, realize turning waste into treasure, and greatly reduce the cost of lead-acid batteries. The process complexity, pollution, energy consumption and cost level of recycling processing have high economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of battery recycling, in particular to a processing method for recycling waste lead storage batteries. Background technique [0002] In recent years, with the continuous increase of energy demand in human society, batteries, as a portable energy storage device, account for an increasing proportion in society and people's daily life, and at the same time, the amount of waste batteries produced is also increasing , If these discarded batteries are not properly disposed of, they will cause serious harm to people's living environment and human health. [0003] Lead-acid batteries, referred to as lead batteries, are the batteries with the largest production volume and the most widely used ways in the world. At the same time, they are also the batteries with the largest amount of decommissioning. If the waste lead-acid batteries are not disposed of in time, the highly toxic heavy metal lead inside them will direc...
