Problems solved by technology

When the paper web exits 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, resulti...

Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] Such as Figure 1~3 As shown, the drying cylinder surface cleaning device is used to clean the drying cylinder 1. The paper 11 to be dried passes through the drying cylinder 1 under the guidance of the guide roller 12 and performs drying operations on the drying cylinder 1. The drying cylinder 1 direction of rotation as figure 1 As shown by the arc-shaped arrow in the middle; the drying cylinder surface cleaning device includes a spraying device, a scraper 3, a friction roller 4, a cleaning roller 5, and a miscellaneous suction device in sequence according to the direction of rotation of th...

Abstract

The invention relates to a drying cylinder surface cleaning device, comprising a spraying device, a scraper, a friction roller, a cleaning roller and a miscellaneous suction device. The spray sprayed by the spraying device promotes the sticky particles on the cylinder body of the dryer to aggregate into flocs, the binding force between the flocs and the cylinder body of the dryer is significantly reduced, and the flocs and fine fibers are After the initial cleaning of the scraper, the second cleaning of the friction roller, the third cleaning of the cleaning roller, and the fourth cleaning of the dust suction device, the effect is obvious, avoiding the phenomenon of sticking to the cylinder and paper breakage accidents, and avoiding the occurrence of drying The surface of the paper will produce oil spots, which will help improve the drying efficiency of the dryer and reduce 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...
