[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This environmentally friendly, low-chlorine-residue bleaching device for corrugated base paper introduces clean water into a hot water tank via an inlet pipe. The heating element heats the water into hot water, which is then pumped into a cleaning tank. The bleached corrugated base paper is placed in the cleaning tank, where the hot water cleans the paper, dissolving any remaining chemicals on its surface.

This environmentally friendly, low-chlorine-residue bleaching device for corrugated base paper uses a first motor to drive a first rotating shaft, which stirs the chemicals inside the bleaching tank, thus initially preventing the chemicals from settling. Then, an air pump delivers filtered air to the hollow plate through an air filter plate, and the filtered air is discharged into the bleaching tank through the air outlet. The air bubbles then agitate the chemicals, further preventing the chemicals from settling. This device can prevent the chemicals from settling and improve the bleaching effect of corrugated base paper. Attached Figure Description

After the corrugated paper is bleached, it is placed in the cleaning tank 300. At this time, clean water is introduced into the hot water tank 340 through the water inlet pipe 341, and the heating element 350 heats the clean water into hot water. Then, the hot water is delivered to the cleaning tank 300 through the water pump 360. At the same time, the ultrasonic generator 330 and the ultrasonic transducer 320 perform ultrasonic cleaning on the corrugated paper. Finally, the solenoid valve 390 is opened, and the drain pipe 380 discharges the wastewater generated during cleaning.
