A paper drying device

Abstract

The invention discloses a papermaking drying apparatus. The papermaking drying apparatus comprises a drying box, wherein four drying apparatuses are arranged inside the drying box, each drying apparatus comprises a heating roll and a heating arc plate, a first cavity is arranged inside each heating roll, a metal pipe is arranged inside each first cavity, magnetic induction loops which are distributed at an equidistance are wounded on each metal pipe, a second cavity is arranged inside each heating arc plate, vent holes which are uniformly distributed are formed in one side surface, close to the corresponding heating roll, of each heating arc plate, the lower surface of the drying box is provided with a heater, the inner wall of the bottom of the drying box is provided with an exhaust transverse pipe, the heater is communicated with the exhaust transverse pipe by virtue of an air transport pipe, a draught fan is arranged inside the air transport pipe, and hot air gaps which are distributed at an equidistance are formed in the exhaust transverse pipe. The papermaking drying apparatus improves the drying effect, improves the drying efficiency, and greatly improves the production efficiency; and the papermaking drying apparatus is simple in structure, small in occupation area and capable of greatly decreasing the production cost of enterprises.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a drying device for papermaking. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. In the paper preparation process, the drying process is the last process of the entire papermaking process. After several processes such as beating, washing and filtering, pulp extraction, stirring, sedimentation, and paper forming, it is dried by a drying device. In a general paper machine, the drying system adopts a steam drying cylinder, which needs to be specially equipped with a boiler and high-pressure pipes, requires a large area of ​​space, and the cost of equipment is high, accounting for almost half of the cost of a complete set of equipment. One, and hi...
