一种真空带式过滤机传送带滑台式支撑装置
本技术涉及固液分离装备
,具体是一种真空带式过滤机传送带滑台式支撑装置。
技术介绍
传送带支撑装置是真空带式过滤机的重要组成部分,其主要作用是支撑过滤机主传送带平稳向前运行。常见传送带支撑装置主要有两种形式:辊子支撑式和气垫支撑式。气垫支撑式的主要缺点是需要风机持续送风来支撑过滤带,能耗较高。辊子支撑式如图1、2所示,在机架1上间隔枢设多个辊子2,辊子2旋转支撑回转运动的传送带3,传送带3上抵接随动的过滤带4,这种辊子支撑式的主要缺点是:一是成本较高,每根辊子都需要配备轴承;二是辊子与传送带之间是线性接触、滚动接触且辊子与辊子之间存在的间隙与传送带的长度方向一致,而传送带在长度方向上是可以弯曲的,在重力的作用下,辊子与辊子之间的传送带会下垂,影响过滤带的平整度,导致滤饼5开裂,真空泄露,真空度降低,从而导致过滤效果不佳。
