Abstract

The invention relates to a high-efficiency and environment-friendly drying device, which belongs to the technical field of papermaking machinery and equipment. It is characterized in that: it comprises a rack, a drying box is arranged on the rack, and a cylindrical rotating mesh cage with open ends at both ends is laterally arranged in the drying box, and the rotating mesh cage is connected with the rotating driving device of the mesh cage; The front end of the rotating mesh cage is provided with a mixed air supply system; a paper feed hole is set on the bottom surface of the drying box, a paper feed drive guide roller is set at the paper feed end of the paper feed hole, and a paper output end of the paper feed hole is provided. Set the paper output drive guide roller; set up an air outlet on the upper top plate of the drying box, and install an induced draft fan on the air outlet. The invention can improve the drying rate of the paper, and the quality of the paper web after drying and setting can be significantly improved.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly drying device, which belongs to the technical field of papermaking machinery and equipment. Background technique [0002] In the existing drying equipment of the paper machine, when drying the formed paper, the hot air is generally directly supplied in the oven, so as to take away the moisture of the paper on the roll, and achieve the effect of drying. However, this drying method is extremely inefficient and wastes a lot of energy. In order to accelerate the evaporation rate of paper moisture, three aspects need to be improved: first, the evaporation area needs to be increased; again, the evaporation temperature and surface air velocity need to be increased. The applicant has gone through many research and development tests with a scientific and rigorous attitude, and has designed a rotary mesh cage with a hollow chamber and a hollow surface. Drying the paper on the side not only inc...
