TGSS-50型水平刮板输送机设计 设计概况 刮板输送机是输送粉尘状、小颗粒及小块等散状物料的连续输送设备，可以水平、倾斜和垂直输送。MS即指水平型输送机，由于输送时，刮板链条全被埋在物料之中，故称为MS埋刮板输送机；又因为埋刮板机槽宽是500mm所以称为MS50型刮板输送机。输送物料具有内擦力和侧压力等特性。垂直输送时，主要依赖物料所具有的起拱特性。封闭机槽内的物料在受到刮板链条在运动方向的推力，且受到下部不断的给料而阻止上物料下滑的阻力时，产生横向阻力时，产生横向侧压力，从而增加物料的内摩擦力，当物料之间的内摩擦力大于物料和侧壁间的外摩擦力及物料自重时，物料就随刮板链条在运动中有振动，有些物料的料拱会时而形成，因而使物料在输送过程中对于链条产生一种滞后现象，影响输送能力。埋刮板输送机主要由封闭断面的壳体（机槽）、刮板链条、驱动装置及张紧装置等部件组成。其设备结构简单、体积小、密封性能好、安装维修比较方便；能多点加料、多点卸料，工艺选型及布置较为灵活；在输送飞扬性、有毒、高温、易燃易爆的物料时，可改善工作条件，减少环境污染。埋刮板输送机目前已被广泛应用于化工、建材、冶金、电力、粮食、轻工和交通领域。MS型埋刮板输送机是采用倾斜度较小或水平布置的一种刮板输送机，其倾角一般为0。≤a≤15。。单台设备的输送高度不大于80m。 关键词：输送料拱内摩擦力外摩擦力侧压力 Desig
