Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling, in particular to a device for cleaning the shell of a waste lead-acid battery. Background Art

[0002] The recycling management of waste lead-acid batteries has gradually entered the orderly management stage. The public's environmental awareness has gradually increased, and the government has gradually paid attention to it. In combination with the characteristics of each country, relatively complete policies, regulations or standards have been formulated and implemented effectively. A relatively complete system has also been established in the specific waste battery recycling organization, and a virtuous "closed-loop" cycle has gradually formed between users, recyclers, lead recycling plants, and battery plants.

[0003] The amount of waste lead-acid batteries for cars and electric bicycles increases year by year, and the total amount is huge, which has a great impact on the environment. The existing battery shells are mostly made of plastic. In order to reduce the pollution to the environment, it is very necessary to carry out secondary processing and utilization. However, the existing battery processing method is to directly crush the battery and then sort the plastic shell for cleaning. In the recycled battery, due to the large amount of impurities left on the shell, when the battery is crushed, the impurities in the battery shell will also enter the battery crushed material, thus increasing the later screening process and cost. Therefore, it is very necessary to remove the impurities outside the battery shell before crushing the battery.

[0004] The patent document with application number CN202220044743.9 and titled "A device for cleaning the casing of used lead-acid batteries" discloses a device for cleaning battery casing fragments. The patent does not disclose a solution for removing impurities attached to the battery casing before the battery is crushed.

[0005] The document with application number CN201520818262.9 and titled "A Battery Shell Cleaning and Drying Device" discloses a device capable of cleaning the battery shell. The battery is transported by tracks and enters the cleaning box and drying box in turn. At the entrance of the cleaning box, the fixed clamps on both sides fix the battery, and the fixed clamps slide forward through the track to prevent the battery from deviating from its position under the action of the cleaning brush and failing to achieve the intended cleaning effect. In the cleaning box, the high-pressure nozzle supplies water through the water tank and sprays high-pressure water mist to the battery that needs to be cleaned. At the same time, the cleaning brush in the cleaning box rotates at the same time to clean the surface of the battery shell, so that the battery is cleaned during transportation. Afterwards, the battery passes through the partition, and the water-absorbing material on the partition can absorb part of the moisture on the surface of the battery shell, and then the battery enters the drying box for drying. However, this patent cannot rinse the bottom of the battery, and the battery cleaning is not thorough. Utility Model Content
