Example Embodiment

[0051] Example 1

[0052] A dry recovery process for waste and maintenance-free storage batteries, the process includes the following steps:

[0053] (1) Feeding: collect waste and maintenance-free batteries and place them in storage bins;

[0054] (2) One-time sawing: the waste and maintenance-free batteries in the silo are transported to the one-time sawing device with a conveying capacity of (14-15) t / h for sawing. After the sawing is completed, the battery body and battery cover are obtained;

[0055] (3) Multiple sawing: the battery body (13-15) t / h obtained in step (2) is transported to the secondary sawing device for simultaneous secondary sawing of the battery body, and sawing into three sections of battery body Scrap

[0056] (4) The battery cover obtained in step (2) is crushed in a hammer crusher to obtain mixed scraps of plastic and battery poles;

[0057] Among them, the grate hole of the crusher is 150×50mm; the working power of the crusher is (180~200)kW.

Abstract

The invention discloses a dry recovery process for a waste maintenance-free storage battery. The process comprises the following steps: feeding, sawing a waste battery at one time, sawing a battery main body for multiple times, crushing a battery cover, screening mixed materials, and winnowing the mixed materials to respectively obtain plastic and a lead grid; namely, the waste maintenance-free battery is separated and recovered by the dry recovery method, plastic and the lead grid in the waste maintenance-free storage battery are recycled through a simple and easy-to-control recycling process, no extra resource is added in the recycling process, no waste is generated, secondary pollution to the environment is avoided, the recycled plastic is reused, and the obtained grid is recycled; in the recycling process, the crushing and screening processes are carried out in the device, and thus no pollution is caused to the surrounding environment; the process is simple, efficient, safe, pollution-free, low in cost and low in resource consumption; and the process has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of battery recycling, and in particular relates to a dry-type recycling process for waste and maintenance-free batteries. Background technique [0002] The working principle of the maintenance-free battery is still basically followed by the traditional lead-acid battery. Its positive active material is lead dioxide (PbO2), the negative active material is spongy metal lead (Pb), and the electrolyte is dilute sulfuric acid (H2SO4). . The design principle of the maintenance-free battery is to inject the required amount of electrolyte into the plates and separators. There is no free electrolyte, and the ability to absorb oxygen is improved through the wetness of the negative plate, and the battery is sealed to prevent the electrolyte from decreasing. Compared with traditional batteries, maintenance-free batteries have made important improvements in structure and materials. They have excellent characteristics su...
