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.

Embodiment 1

[0024] Such as figure 1 As shown, a waste plate lead paste recycling device includes a centrifugal device 1 and a lead slime collecting device 2 connected to the centrifugal device 1 . The centrifugal device 1 has a feed port 12 and a mud outlet 13. The centrifugal device 1 has a centrifugal barrel 11 inside, and the side wall and the bottom surface of the centrifugal barrel 11 have lead mud holes, and the diameter of the lead mud holes is 5-8mm. Centrifugal barrel 11 is driven to rotate by motor 17 .

[0025] The top surface of the centrifugal device 1 is open, and has a loam cake 14 covering the opening. The feed port 12 is located on the loam cake 14 and is positioned directly above the centrifuge bucket 11. Feeding bin 15. The bottom surface of the upper cover 14 is provided with a photoelectric sensor 16 for detecting waste plates. The setting of the upper cover 14 facilitates opening the upper cover 14 after a centrifugation is completed, and the remaining grids in th...

Abstract

The invention discloses a lead paste recycling device of a waste pole plate and a lead paste recycling method. The lead paste recycling device of the waste pole plate comprises a centrifugation device, a spraying pipe and a lead mud collection device, wherein the centrifugation device is provided with a material inlet and a mud outlet, a centrifugation barrel is arranged in the centrifugation device, lead mud holes are formed in a side wall and a bottom surface of the centrifugation barrel, the material inlet is arranged right above the centrifugation barrel, the spraying pipe extends into thecentrifugation barrel, the lead mud collection device is in linkage with the centrifugation device and comprises a liquid collection groove, and a filtering plate is arranged at the top of the liquidcollection groove and is used for filtering and collecting lead mud. The lead paste recycling device of the waste pole plate is special used for recycling lead paste in a pole plate which has unfavorable appearance or is ultra light or ultra heavy, the processing efficiency is high, recycling is thorough, moreover, the lead paste on the pole plate can be effectively prevented from being oxidizedand dehydrated during the recycling process, the stability and the consistency of the recycled lead paste are ensured, and the performance of a final battery is not affected by recycling.

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...
