AI Technical Summary
Technical Problem
In a round mesh paper machine, high slurry speed causes the slurry fiber to flocculate, affecting the uniformity of fiber dispersion, and thus affecting the quality of the paper.
Method used
A slurry uniform mechanism of circular mesh paper machine is designed, and the slurry pass-through structure and homogenize rollers are used to form convection and small vortex, combined with paddle agitation, strengthen the fiber dispersion effect and avoid flocculation.
Benefits of technology
Through the design of convection and small vortex, the slurry fibers can be effectively dispersed, the flocculation will be avoided, the fiber dispersion will be improved, and the paper quality will be improved.

Abstract
The utility model relates to the technical field of papermaking equipment, in particular to a pulp leveling mechanism of a rotary screen paper machine, which comprises a pulp flowing box, pulp feeding structures are fixedly connected to two sides in the pulp flowing box, a pulp homogenizing structure is rotatably connected between the two pulp feeding structures and comprises a pulp homogenizing roller, and side plates are fixedly sleeved on the surfaces of the outer sides of two ends of the pulp homogenizing roller. The edges of the side plates are rotationally connected with the inner walls of openings in the two sides of the outer cylinder through second sealing bearings, a slurry outlet is formed in the cylinder wall of the front side of the outer cylinder at a 45-degree elevation angle, and a slurry homogenizing roller is rotationally installed in the outer cylinder. According to the utility model, the slurry is thrown into the outer cylinder from each hole of the homogenizing roller and collides with the inner wall of the outer cylinder, and the slurry outlet is higher, so that the retention time of the slurry in the outer cylinder is prolonged, and when the slurry stays in the outer cylinder, the slurry repeatedly enters the homogenizing roller again from each hole of the homogenizing roller and then is thrown out; and the flocculated fiber agglomerates are scattered and dispersed again.
