Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushing and recycling of waste lead-acid batteries, in particular to a device for removing AGM separators from crushed materials of waste lead-acid batteries. Background Art
[0002] Ultrafine glass fiber separator, commonly known as AGM separator. AGM separator is mainly made of glass fiber with different decomposition degrees, and is made of wet papermaking technology in different proportions. As an indispensable material in lead-acid batteries, it brings many benefits to the battery. The main functions of AGM separator for lead-acid batteries are: (1) to prevent the positive / negative plates from contacting each other and causing internal short circuit of the battery; (2) to make the battery tightly assembled and reduce the battery volume; (3) to prevent the deformation, bending of the plates and the shedding of active substances; (4) as a porous separator between the plates, it can store the necessary amount of electrolyte to ensure high conductivity and meet the needs of battery reaction; (5) to prevent some substances harmful to the battery from migrating and diffusing through the separator; (6) to realize oxygen circulation inside the lead-acid battery. Therefore, AGM separator is called the third plate of lead-acid battery.
[0003] However, in the battery recycling stage, after the waste batteries are violently crushed by a crusher, the crushed materials are composed of AGM separators, PE separators, lead paste, lead grids, plastic sheets and other parts. In the existing crushed material sorting, the density of the aqueous solution is adjusted and multi-stage sorting is used to classify the AGM separators, PE separators, lead paste, lead grids and plastic sheets. However, since the AGM separators are cotton separators with a multi-fiber structure, the water liquid cannot effectively penetrate the inside of the separators, causing the AGM separators to float on the water surface along with the plastic sheets during the water sorting process. The existing multi-stage sorting technology cannot effectively separate the two types of substances, AGM separators and plastic sheets, through the density of the aqueous solution, which has a negative impact on the subsequent recycling and re-creation, and the quality of plastic granulation, resulting in a high scrap rate of battery casings produced by downstream factories.
