Abstract

The invention relates to a papermaking equipment, comprising a screw press machine, a plug screw conveyor whose feed port communicates with the discharge port of the screw press machine, and a shredder whose feed port communicates with the discharge port of the plug screw conveyor , a heater whose feed inlet communicates with the discharge outlet of the shredder, and a disc-type heat disperser whose feed inlet communicates with the heater outlet, and is characterized in that the first spindle of the screw press is provided with a disc There are two left-handed impellers and right-handed impellers with opposite rotation directions. The main shaft between the left-handed impeller and the right-handed impeller is also equipped with stirring teeth; the third main shaft of the shredder and the fourth main shaft of the heater are set on the disk The impeller is divided into a complete impeller segment and a toothed impeller segment. Compared with the existing technology, Simple and compact structure, small footprint, no empty return, easy maintenance ,efficient.

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...
