The roller surface of the vacuum roller is provided with suction holes that penetrate the roller surface. A suction element is provided inside the roller. The suction element is provided with a suction port facing the inner wall of the roller. As the roller rotates relative to the suction element, the suction holes on the roller surface periodically pass through the suction port of the suction element. The vacuum roller is one of the main dehydration components on the papermaking machine. It is used in the wire and press sections. It can improve the dehydration efficiency, increase the dryness entering the drying section, and reduce the steam consumption of the drying section.

[0003] After the vacuum roller has been used for a period of time during shutdown and flushing, its holes will gradually become clogged. During production, the clogged holes often cause paper breaks, reduced water absorption capacity, and high humidity in the paper sheets. Especially at the two ends of the vacuum chamber, due to the division of the partition, fine impurities and dust are not easy to be extracted, and the holes of the vacuum roller are more likely to become clogged, affecting production.
