Abstract

The invention relates to a papermaking device. The papermaking device comprises a screw pulp squeezer, a material plug screw conveyer with a feed inlet communicated with the material outlet of the screw pulp squeezer, a shredder with a feed inlet communicated with the material outlet of the material plug screw conveyer, a heater with a feed inlet communicated with the material outlet of the shredder, and a disc-type heat disperser with a feed inlet communicated with the material outlet of the heater. The papermaking device is characterized in that a section of a left rotating impeller and a section of a right rotating impeller with opposite rotation directions are circled around a first main shaft, the main shaft between the left rotating impeller and the right rotating impeller is equipped with stirring teeth, Impellers circled around the third main shaft of the shredder and the fourth main shaft of the heater are a complete impeller section and a tooth-shaped impeller section. Compared with the prior art, the papermaking device is advantaged by simple and compact structure, small occupation area, no empty return, convenient maintenance and high efficiency.

Description

technical field [0001] The invention relates to a papermaking equipment, in particular to a screw agitating squeezer which can effectively disperse impurities such as stickies, grease, paraffin, plastic, rubber or ink particles in waste paper slurry. Background technique [0002] Driven by productivity, the modern paper industry has developed rapidly, resulting in the characteristics of large quantities and short service life of modern paper products. The resulting paper waste has caused huge pollution to the environment and seriously affected the quality of human life. Moreover, packaging materials are developing the fastest, and their recycling and reuse can obtain obvious ecological benefits and economic benefits, which have become the focus of development and utilization. At present, wastes such as paper products and paper packaging are usually recycled by repulping. For the treatment of hot-melt materials such as ink particles in waste paper pulp, a roller heat disper...
