Description
Technical Field
The utility model relates to the technical field of papermaking mechanical equipment, in particular to a paper machine drying cylinder with a heat insulation structure.
Background
In the process of making paper, a drying cylinder is an indispensable important device, and after the paper making is finished, drying must be carried out by the drying cylinder. Paper machine cylinders are usually composed of a cylinder tube, a cylinder head and a shaft head. When the drying cylinder works, the heating medium passes through the inner surface of the cylinder barrel, heat is transmitted to paper outside the cylinder barrel through the wall of the cylinder barrel, and moisture in the paper is dried. The traditional drying cylinder of the paper machine is heated mainly by adopting steam generated by a steam boiler, water in the boiler is heated and evaporated into steam, then the steam is sent into the drying cylinder of the paper machine to heat the drying cylinder, and in the heating process, the heat of the steam cannot be fully utilized, for example, the connection position of the cylinder body and the cylinder cover often leaks air, and the cylinder cover is not insulated; in addition, the condensed water generated by the liquefaction of the steam cannot be discharged in time, and the drying efficiency of the drying cylinder is influenced.
