Description

Technical Field

[0001] The utility model relates to the technical field of papermaking technology and belongs to a pulp beating and refining device for special paper production. Background Art

[0002] The process of using physical methods to mechanically or fluidly treat the pulp fibers in water, subjecting the fibers to shear forces, changing the fiber morphology, and giving the pulp certain characteristics to ensure that the paper produced meets the expected quality requirements, is called "beating". In the beating process, in addition to being sheared, rubbed, and combed by the machine, the fiber cell walls also undergo displacement, deformation, and rupture, absorbing water and swelling, producing fine fibers, making the pulp soft and plastic, and increasing the chances for the hydroxyl groups in the cellulose molecular chains to combine with hydrogen chains, thereby improving the bonding force between fibers.

[0003] In the current pulp beating process, some pulp will sink to the bottom of some pulping devices, or the pulping mechanism cannot reach the pulp when the water level is low. This can easily lead to a low degree of refinement in the pulp processing by the pulping device, and the pulp uniformity after pulping is still somewhat insufficient, which will have a long-term impact on the quality of subsequent products. Therefore, an efficient pulp beating and refining device that can ensure quality is needed. Utility Model Content
