Principles of the fluid mechanics of flows through orifice are adopted to direct screen plate manufacturing. Fluids flowing through orifices will begin to "shrink". If the thikness of the screen plate is equal to 2-3 times the diameter of the orifice, instantaneous vacuum at orifice walls will be created by the "shrinkage" of fluids, vacuum thus created may reached up to 80% of the effective fluids head. As a result, about 34% increase in flow rate may be effected. It is possible to deduce, then,...

Principles of the fluid mechanics of flows through orifice are adopted to direct screen plate manufacturing. Fluids flowing through orifices will begin to "shrink". If the thikness of the screen plate is equal to 2-3 times the diameter of the orifice, instantaneous vacuum at orifice walls will be created by the "shrinkage" of fluids, vacuum thus created may reached up to 80% of the effective fluids head. As a result, about 34% increase in flow rate may be effected. It is possible to deduce, then, the following formula for optimum thikness of screen plates. (3 = 2.5d. If a conical-shaped orifice of 4°-7°is chosen, maximum flow rate will be achieved with highest possible vacuum in action, with a 13°24′ conical-shaped orifice, a maximum back washing velocity of screened pulp dispersion will be attained, giving a more thorough cleaning of plates in pressure screens. Consequently, orifices should be drilled to give different conical shapes to conform with the requirements of screen designs and their related operating parameters.

本文作者从流体力学的基本原理出发,探讨了造纸工业广泛使用的压力筛和离心筛等筛板合理的厚度及小孔锥度,具有一定的见解,文中内容值得引起国内设计、制造和使用筛浆机的科技工作者注意。诚然,在将流体力学的原理和公式应用于约4%浓度的浆料时,最好能够通过实验予以验证,这还有待于进一步实践和探讨。

The development of screens applied in pulp processing is reviewed briefly in this paper. Also, the unique constructure and the working principle for Centrisorter are discussed in some details.The Centrisorter model pressure screen operates at higher consistencies, up to 2. 5% or more, and higher capacity than conventional screens with the advantages of high shive removal efficiency, low specific power Consumption and low water consumption , etc.Jiamusi Paper Mill introduced two sets of model M400 and one set of M200 pressure screens from Ahlstrom, Finland. As an example, the working conditions and the process parameters for the M200 is introduced in more details. The operational experiences and benefits are discussed. Three figures are also presented in this paper.

旋鼓式压力精选机是一种新型的纸浆筛选设备。它具有筛选效率高、用水量低。工艺流程较简单,纤维损失少等特点。压力精选机的出浆浓度高,通常为1.5%~2.5%,比普通的压力筛高得多;占地面积小,生产能力大。本文介绍旋鼓式压力精选机在硫酸盐制浆系统中的应用实践。

Production of the reconstructed paper machine becomes normal while consumption decreases and paper quality is improved after several new equipments have been installed on the machine, which include large low pulse pressure screen, fan pump, cleaner system, Sym-Fol headbox, crown controlled stainless...

No. 5 PM of Guangzhou Papet Mill with a design capacity of 100t/d, speed of 450m/min and trim width of 3990mm imported from Finland in 1955, has been reconstructed recently after running more than 35 years. Production of the reconstructed paper machine becomes normal while consumption decreases and paper quality is improved after several new equipments have been installed on the machine, which include large low pulse pressure screen, fan pump, cleaner system, Sym-Fol headbox, crown controlled stainless steel press and calender roll ect. Remarkable profit has been realized from this reconstruction.
