作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。
Based on the analysis of the structure and working principle of the pneumatic mud shale shaker and its kinetics, the calculation method of the pneumatic shaker and exciter is obtained. It is also pointed out that the screen surface inclination, the excitation frequency and the amplitude of the pneumatic vibrating screen can be adjusted as needed, so as to find a way to design a new type of mud screen. At present, almost all of the screening machines used to purify the slurry are single-axis inertial vibrating screens. The frequency of such a slurry screen can not be changed, and the adjustment range of amplitude and screen face inclination is small. However, a large number of studies have shown that among the many factors that affect the amount of sieve treatment and screening effect, the size of kinematic parameters such as amplitude, frequency and screen face angle occupy an important position. Therefore, the new generation of mud screen not only has the advantages of simple and reliable structure, but also should be easy to adjust the amplitude, frequency and screen angle, in order to meet the different performance, different cuttings content and different displacement mud treatment requirements . Pneumatic shale shaker can easily achieve the above requirements, is a promising mud screen.
