Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking machine auxiliary equipment technology, specifically a drying mechanism for a papermaking machine. Background Technology
[0002] Paper machine drying equipment is a key post-processing device in the paper production process. The superheated air fan sends hot air into the drying chamber, so that the moisture in the paper is evaporated under the action of hot air, thereby achieving the purpose of drying. The heat energy of steam is used to transfer heat to the paper through heat conduction, causing the moisture in the paper to evaporate. After the steam condenses into water in the drying cylinder, it is discharged through the condensate drainage system to ensure the heat transfer efficiency of the drying cylinder.
[0003] Existing drying mechanisms for paper machines use a dryer in conjunction with a moving roller to dry the pulp. However, this method results in uneven drying, long drying time, and low drying efficiency. Therefore, we propose a new drying mechanism for paper machines. Utility Model Content
