[0003] It is not convenient to replace the activated carbon in the existing decolorization device. Generally, the decolorization device uses activated carbon for decolorization.

Generally, the activated carbon is located inside the device. When replacing it, the device needs to be disassembled and opened, and then the activated carbon is taken out of the device with tools, and then new activated carbon is loaded into the device. Since the activated carbon is granular, it is more troublesome to take it out, which increases the workload and reduces the work efficiency.
