埋刮板输送机输送中的问题引文注释

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。设备结构简单、体积小、密封性能好、安装维修比较方便；能多加

点料、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。埋刮板输送机是输送粉尘状、

小颗粒及块状等散状物料的连续输送设备，可以水平、倾斜和垂直输送。散料具

有内摩擦力和侧压力等特性。水平输送时，物料受到刮板链条在运动方向的推力

，当料层间的内摩擦力大于物料与槽壁间的外摩擦力时，物料就随着刮板链条向

前运动。在料层高度与机槽宽度之比值满足一定的条件时，料流是稳定的。含水

率：含水率与物料的料度、粘度有关，一般应以手捏成团撒手后能松散为度。而

被破坏，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。http://www.ayzsb.com
Buried scraper conveyor is mainly composed of a casing closing section

(slot machines), the scraper chain, driving device and the tensioning

device and other components. The equipment has the advantages of

simple structure, small volume, good sealing performance, convenient

installation repair; can add more material, multiple points

discharging, process selection and layout of the more flexible; in

transport flying, high temperature, toxic, flammable and explosive

materials, can improve working conditions, reduce environmental

pollution. Buried scraper conveyor is continuous conveying equipment

for conveying powder dust, small particles and bulk and other bulk

materials, can be horizontal, tilt and vertical transmission. Bulk

material has the friction and side pressure characteristics. The

horizontal transport of materials by the scraper chain, thrust in the

direction of motion, when the internal friction material layer between

the outer friction material and the walls of the groove between the

material, the scraper chain forward movement. In the material ratio of

height and the slot width when certain conditions are met, the

material flow is stable. Moisture: moisture content and concentration,

viscosity materials, should be to hand into the group go to loose

degree. And destroyed, and the formation, so that the material in the

conveying process for chain produces a hysteresis phenomenon,

affecting transmission capacity.
