Abstract

The present invention relates to an oil-heating drying device for making paper, belonging to the field of papermaking drying device technology, it includes a cylinder dryer and its two end covers. Said two end covers are equipped with rotating shaft respectively, in the interior of every rotating shaft a hole is cut, in one end hole interior an oil inlet tube is set, and in another end hole interior an oil outlet tube is set, in the cylinder dryer, on the end cover on which the oil inlet tube is mounted a central supporting frame is mounted, said oil inlet tube is placed in the inner hole of said central supporting frame, in the cylinder dryer interior the end portion of said oil inlet tube is connected with an oil distributor, under the oil distributor an oil-pressing plate is mounted along the cylinder rotation direction.

Description

technical field [0001] The invention belongs to the technical field of drying devices for papermaking, in particular to an oil heat drying device for papermaking. technical background [0002] In the prior art, the drying cylinders used in the paper industry are generally heated by steam. Since steam boilers must be used, the investment in equipment is large, the energy consumption is high, the thermal efficiency is low, the amount of smoke exhaust is large, and the environment is seriously polluted. Boilers are pressure boilers, which are not safe and require high operating skills for boiler workers. No. 99247129.X patent provides an oil-heated paper-making drying device after retrieval. A high-temperature circulating oil pump is installed between the "oil-heated energy-saving boiler" and the drying parts on the paper-making machine, and passes through pipelines, oil separators, The rotary joint pumps the heated high-temperature (up to 320°C) heat transfer oil directly int...
