A kind of lead plaster recycling device and method for recycling lead plaster of waste plate

Abstract

The invention discloses a lead plaster recycling device for waste pole plates and a lead plaster recycling method. A waste electrode plate lead plaster recovery device, comprising: a centrifugal device with a feed inlet and a mud outlet, the centrifuge device has a centrifugal bucket inside, and the side wall and bottom surface of the centrifuge bucket have lead mud holes. The feed inlet is located directly above the centrifuge bucket; the spray pipe extending into the centrifuge bucket; the lead slime collecting device connected to the centrifugal device, including a sump, the top of the sump is provided with a filter plate for filtering and collecting lead slime. The waste plate lead paste recovery device of the present invention is specially used to recycle and reuse the lead paste in the poor appearance or ultra-light and overweight plates produced during the process of plate coating. The processing efficiency is high, the recovery is thorough, and it can effectively Control the oxidation and dehydration of the lead paste on the plate during the recycling process to ensure the stability and consistency of the recycled lead paste, and the reuse will not affect the performance of the final battery.

Description

technical field [0001] The invention relates to the technical field of lead storage battery production, in particular to a waste plate lead paste recycling device and a method for recycling lead paste. Background technique [0002] The synthesis of lead paste is a very critical process in the manufacturing process of lead-acid batteries. It is a paste made by mixing (stirring) lead powder, pure water, dilute sulfuric acid solution, and various additives. The important purpose of the paste mixing process is to mix various materials evenly and have a suitable phase composition to ensure that the battery has high capacity and long life. In the production process of lead-acid batteries, there are often some waste lead pastes that need to be recycled and reused. [0003] For example, the Chinese utility model patent with the authorized announcement number CN204720516U discloses a lead paste recovery equipment, which includes a bracket and a recovery kettle mounted on the bracket...

AI Technical Summary

Problems solved by technology

During the recycling process, the lead paste will be oxidized and dehydrated in the air environment, which will change the phase of the lead paste and affect the stability and consistency of the recycled lead paste.

Blind reuse will inevitably have a bad impact on the final performance of the battery

In addition, the efficiency of manual treatment is low, and the recovery is not complete, which will have an adverse impact on the environment and increase the cost of recycling.
