AI Technical Summary

Technical Problem

Existing papermaking equipment is prone to wrinkling or bulging of the paper web during the drying process, leading to paper defects.

Method used

Design a papermaking processing equipment that introduces anti-wrinkle wire rollers and vacuum sealing boxes into the drying cylinder system, uses vacuum holes and vacuum pipes to form a uniform vacuum, ensures that the paper web is wrinkle-free during the drying process, and uses steam pipes and siphons for heat transfer and water recovery.

Benefits of technology

This effectively prevents wrinkles or bulging of the paper web during the drying process, ensuring the flatness of the paper web and the drying effect.

Abstract

This invention discloses a papermaking processing equipment and method, including a pressure roller to transfer the paper web to the surface of a drying cylinder system for drying. The drying cylinder system consists of several drying cylinder assemblies arranged in parallel along the direction of paper web movement. Each drying cylinder assembly includes a first drying cylinder and a second drying cylinder, which are spaced apart, and an anti-wrinkle wire roller is provided between the first and second drying cylinders. The drying cylinder system, consisting of several drying cylinder assemblies, is fixed by a steel structure truss. The first and second drying cylinders and the anti-wrinkle wire roller constitute the drying cylinder assembly. A steam pipe is provided at one end of the first and second drying cylinders, extending into the interior of the first and second drying cylinders, and connected to several steam conduits arranged along the inner surface of the first and second drying cylinders.
