[0002] With the improvement of living standards, people have an increasingly strong demand for various electronic devices. Batteries are an indispensable part of electronic products. Depending on the electronic device, the type of battery used is also different. Small portable electronic devices such as mobile phones and tablets use ternary lithium batteries, while larger electronic devices such as electric vehicles use lead-acid batteries. Lead-acid batteries are a very widely used type of battery, but after a certain lifespan, they need to be recycled. During the recycling process, a lot of plastic fragments will be generated. These plastic fragments need to be sorted according to different colors. The equipment used in this process is a color sorter.
[0003] Generally, a vacuum silo is used to transport plastic fragments to the color sorter. However, the plastic fragments of the crushed batteries contain dust, which easily leaves dust in the vacuum silo. After a certain amount of dust accumulates, the vacuum silo needs to be cleaned, which affects production efficiency. Therefore, it is particularly necessary to develop a vacuum silo for plastic sorting that reduces dust from entering the vacuum silo and extends the cleaning cycle. Summary of the Invention
