Surface cleaning device for drying cylinder

Abstract

The invention relates to a surface cleaning device for a drying cylinder. The surface cleaning device comprises a chemical spray device, a scraper, a friction roller, a cleaning roller and an impurity absorption device, wherein mist spray sprayed from the chemical spray device is used for prompting sticker particles on a cylinder body of the drying cylinder to be gathered into flocs, so that the binding force between the flocs and the cylinder body of the drying cylinder is significantly reduced; after the flocs and fine fibers rotate to preliminary cleaning of the scraper, second cleaning of the friction roller, third cleaning of the cleaning roller and fourth cleaning of the impurity absorption device along with the drying cylinder, the effect is obvious, the phenomenon of sticking on the cylinder and an accident of paper breaking are avoided, the dried paper surface is also prevented from generating oil spots, and the surface cleaning device is conducive to improvement of the drying operation efficiency of the drying cylinder and reduction of the consumption of the scraper.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a drying cylinder surface cleaning device. Background technique [0002] The extensive use of recycled fibers and the gradual increase in the amount of papermaking chemicals added are two major trends in the current papermaking industry. Regenerated fibers contain a large amount of stickies and fine fibers. When the paper web leaves the press section, the dryness is relatively low. At this time, the stickies are very viscous and easily stick to the surface of the first few drying cylinders in the drying section. In severe cases, it will cause sticking to the cylinders, resulting in paper breaks. At the same time, it is difficult to clean the surface of the drying cylinder during normal production after it is dirty, the consumption of the scraper is also significantly increased, and the operating efficiency of the paper machine is also relatively reduced. Based on the above b...
