气动泥浆振动筛探讨

者通过对气动泥浆振动筛结构和工作原理的分析以及动力学研究,得出气动振动筛和激振器的计算方法。并指出气动振动筛的筛面倾角、激振频率和振幅都能够根据需要调整,从而为设计新型泥浆筛探索出一条路子。 目前,用于净化泥浆的筛分机械几乎都是单轴惯性振动筛,这种泥浆筛的频率不能改变,振幅和筛面倾角的调整范围较小。而大量的研究表明,在影响筛子处理量和筛分效果的众多因素中,振幅、频率、筛面倾角等运动学参数的大小占有重要的地位。因此,新一代的泥浆筛,不但要具备结构简单可靠的优点,而且应当能方便地调节振幅、频率和筛面倾角,才能满足对不同性能、不同岩屑含量和不同排量的泥浆的处理要求。气动泥浆振动筛能够容易地实现上述要求,是一种很有前途的泥浆筛。

A STUDY OF PNEUMATIC SHALE SHAKERS

After analysing the construction and working principles of pneumatic shale shakers and studying the dynamics on pneumatic shale shakers, the calculation formulas of pneumatic shale shakers and vibrators have been obtained by the authors. It is pointed out in the paper that the slope angle of screen surface, excitation frequency and amplitude of pneumatic shale shakers can be regulated according to actual requirements, so that a way is explored for designing a new-type shale shaker.
