Embodiment Construction
[0010] The technological process of the present invention includes pulp crushing process, pulp refining process, pulp storage process, batching process, sand removal and slag removal process, slurry flow process, wet papermaking process, dehydration and drying process, and the batching process is to add adhesive in the batching tank The pigments and adhesives required for the color of the paper will flocculate the pulp into a suspension, separate the pulp from water, and then enter the flow process after the sand and slag removal process. The pulping process is to use the pulp in the headbox to form wet paper by the paper machine, and the wet paper is dehydrated, dried, and trimmed to obtain finished paper. At the same time, after the suspended pulp in the headbox is sucked clean by the paper machine, the remaining working sewage is directly recycled for use.
[0011] In the above process, the paper machine is located at the lower part of the headbox, and its conveyor belt ado...
