Suction Box

Suction box is universally used in paper machine's screen cloth and press section, and functions as extracting, by use of vacuum pump, excess water absorbed on upper wire side of dewatering element or contained in coarse slurry. Suction box may be mounted close to breast roll, or breast roll blade may be mounted in a way capable of backward and forward movement, to adjust the optimum slurry spray impact point and achieve good paper sheet formation and dewatering effects. The texture of a suction box panel includes: a supra polymer polyethylene panel, an aluminum oxide ceramic panel, a zirconia ceramic panel, a glass microcrystal panel, and an embedded ceramic suction box panel. Different ceramics may be selected according to different screen cloth manufacturing processes. The box adopts annealing or movement to eliminate stress, reduce deformation and ensure quality. The surface is subject to sand blasting to achieve elegant appearance. The transition bottom plate adopts the latest material subjected to special treatment and one-time forming, without machining and deformation but having such features as an accurate size, easy pasting, high strength, high hardness, good wear resistance, a low friction coefficient, etc. The panel is entirely machined through a special purpose machine and a special processing technology, to realize high machining precision, a smooth surface, a high degree of finish, and fine and smooth effects. It can avoid the paper defect caused by fiber fines reservation and slurry overflow, and is easy to control waterline to prevent adverse factors for formation of paper sheet in dewatering process. Moreover, it can reduce paper two-sidedness, thereby improving paper uniformity and smoothness greatly. In addition, it can generate water film between net and dewatering
