针对筛网旋流器工作过程中常见的断流和堵筛问题,通过对颗粒到达筛面时两者运动情况的分析,得出两者的相对切向速差必须小于颗粒透筛允许的最大速度,才能够取得良好的透筛效率。提出了一种变静止筛网为转动筛网的筛网旋流器,可以很好地解决筛网旋流器的断流和堵筛现象。 Aiming at the common problems of flow interception and plugging in the operation of the sieve cyclone, the relative tangential velocity difference between the two when the particles reach the sieve surface must be less than the maximum allowed by the particle sieve Speed, we can get a good sieving efficiency. A kind of screen swirler with variable static screen as the rotating screen is proposed, which can well solve the phenomenon of blockage and screen blocking of the screen swirler.
