Embodiment
[0019] A physical method of waste paper deinking process, taking several comprehensive waste papers such as various book papers, electrostatic copy papers, and double-sided printed thick ink propaganda newspapers as examples:
[0020] 1) Tearing: Use a shredder to tear up waste paper such as books, and tear it into pieces of different sizes. At this time, the ink on the waste paper has been cracked under the action of force.
[0021] 2) Deflagging: Use the transmission screw to send the shredded waste paper into the deflaking machine. The mechanism of the deflaking machine is to effectively decompose the shredded waste paper into semi-fibers or fibers. The ink on the waste paper is broken into tiny powders under the action of force, and most of them have fallen off from the fibers along with the paper-making filler.
[0022] 3) Refining: The decomposed semi-fiber and fiber raw materials fall into the pulp well, add water to stir, and send them to the refiner with a pulp pump....
