摘要
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。

Design overview
Scraper conveyor is conveying dust, small particles and small pieces of etc of continuous conveying equipment, vertical and horizontal, tilt. MS horizontal conveyor, because that means, scraper conveyor chains are buried in the material, so called MS scraper conveyor, And because the wind was buried trigger 500mm therefore called slot width MS50 type scraper conveyor. Materials to be conveyed with force and the lateral pressure inside brush etc. Vertical conveyor, which mainly rely on materials of arch characteristics. Sealing material in the slot machine by scraper chain in the direction of movement, and is constantly under the thrust of the feeding and prevent slipping on the resistance, transverse resistance, transverse lateral pressure, thus increasing the friction material, when materials within the friction between the inside wall of the room than material and the friction and weight materials, materials with scraper chain in movement, some materials are of vibration, thus will sometimes arch in the process of conveying material to produce a lag phenomenon chain, transmission capacity. Scraper conveyor consists mainly of closed cross-section of the shell (machine), scraper chain, driving device and a device etc. Parts. The equipment is simple in structure, small volume, sealed performance is good, easy installation and maintenance, Can more charging and discharging points, process selection and arrangement more flexible, The dust, poisonous, high temperature, inflammable and explosive materials, can improve the working conditions, and reduce environmental pollution. Scraper conveyor has been widely used in chemical industry, building materials, metallurgy, electric power, food, light industry and transportation. MS type scraper conveyor is smaller or using gradient layout of a level of scraper coveyor, its Angle is commonly 0. More than a more than 15. The single machine conveyance height is not more than 80m.
Keywords: transport within the friction friction material arch lateral pressure
