Problems solved by technology

In the existing papermaking technology, the drying of paper is completed by heating the iron plate. The semi-finished paper is laid on the iron plate, and the iron plate is heated by steam. This kind of steam heating consumes a lot of energy and is easily affected. Influenced by the interface temperature; there are those who use a fan to blow hot air for heating. This heating method cannot know the temperature in the oven, and the temperature cannot be adjusted in time to affect the quality of the paper.

Abstract

The invention discloses a drying device for papermaking. The drying device comprises a drying oven, a conveying belt, an air blower, an air outlet pipeline, an air inlet pipeline, a heating pipe and atemperature sensor, wherein the temperature sensor is arranged on the inner wall of the drying oven, and is connected with the heating pipe through a temperature regulating switch, the air inlet pipeline is connected with exhaust branch pipes arranged in the drying oven, the exhaust branch pipes are arranged below the heating pipe, exhaust outlets are formed in the exhaust branch pipes at equal intervals, the number of the exhaust branch pipes is 2-5, and the included angle between each exhaust outlet and the heating pipe is 60-90 degrees. The drying device of the invention is simple in structure, low in cost, uniform in heating, capable of adjusting the temperature in the drying oven in time, good in drying effect and good in produced paper.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a drying device for papermaking. Background technique [0002] In the papermaking process, the paper coming out of the press section contains a lot of moisture and needs to be dried. In the existing papermaking technology, the drying of paper is completed by heating the iron plate. The semi-finished paper is laid on the iron plate, and the iron plate is heated by steam. This kind of steam heating consumes a lot of energy and is easily affected. Influenced by the interface temperature; there is a fan blowing hot air for heating. This heating method cannot know the temperature in the oven, and the temperature cannot be adjusted in time to affect the quality of the paper. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a papermaking machine with simple struct...
