节能水力碎浆机改进型转子

摘要

The traditional vertical hydraulic crusher has great energy consumption in the process of crushing pulp, the structure form of the rotor is the main aspect that affects energy consumption,and there are many structural drawbacks in the commonly used Vokes rotor.An improved energy-saving hydropulper's rotor was desighed, which optimized the runner,changed the shape of the blade and strengthened the vortex inner circulation in the process of pulp breaking. The effect of hydraulic cyclic disintegration was effectively used to avoid the lost energy, thus reducing the power loss. The pulper equipped with the rotor can save more than 20% of energy without sacrificing the quality of slurry.%传统立式水力碎浆机在碎浆过程中能耗大,其中转子的结构形式是影响能耗的主要方面,比如现常用的伏克斯转子就存在着许多结构弊端.课题组提出一种改进型节能碎浆机转子,通过优化流道,改变叶片的形态,强化了纸浆碎解过程中的涡流内循环,有效利用了水力循环碎解作用,避免了大量无用功的损失,从而降低了能源损耗.配备了该转子的碎浆机在不牺牲打浆质量的前提下,节约能源20%以上.
