The pulp in the pulp chest is sent into the high box of the paper machine through the sizing pump to stabilize the sizing pressure. Before the slurry enters the high-level box, it passes through a thick adjustment to stabilize the sizing concentration. After the slurry is stabilized by the high level box, it flows to the inlet of the slurry pump by itself. Before the pulp flows to the inlet of the pulp pump, it passes through a quantitative control to stabilize the sizing flow and control the paper weight.
After the slurry is diluted and mixed by the slurry pump, it enters the inflow pressure screen, reduces the pulse and removes foreign impurities, and then enters the headbox. The headbox is equipped with pressure control, and through interlocking with the pulp pump, the pulp wire speed ratio can be adjusted to meet the speed change requirements.
The pulp is sprayed from the lip of the headbox with a concentration of 0.15~0.25%, and after being centrifugally dehydrated by the forming roller, it leaves the wire section with a dryness of 20~22% and is brought into the vacuum roller through the felt, and is dehydrated by vacuum pressing, and then enter the drying cylinder with a dryness of 38~40% to dry. After the paper sheet is dried, it is wrinkled by a doctor blade, and then leaves the dryer cylinder and enters the reeling section.
