一.用途及特点(characteristic and usage) 螺旋输送机是一种通用型、短距离运输设备。广泛使用于冶金、
矿山、煤炭、化工、建材、粮食等行业。
Screw conveyer is a kind of general equipment, which is widely applied to metallurgy, mining, coal, chemical, construction and food industries.
螺旋输送机可单机使用亦可多台联机组成一个运输系统。既可满足水平输送亦可成一定倾角提升运输。是一种结构简单性能优良的连续
运输设备;主要用于输送粉状颗粒状和小块物料;它不宜输送易变质的粘性地和易结块的物料。使用的环境温度为-20~50ºC,物料温度小于200ºC,输送机的倾角小于20º。
Screw conveyor can used a single machine, or equipped with other machines to union a conveying system. It’s such kind of machine, simple structure as well as superior performance, could satisfied the horizontal as well as slope material conveying. And mainly used to conveying powder, pellet or small size material, not suitable to cohesive material, or something easy to caking together. Operating environmental temperature is -20~50ºC, the temperature of material should be lower than 200ºC. incline angle less than 20º.

二.主要技术参数:
The Main Technical Parameter
1.螺旋直径(screw diameter): ø300mm
2.螺旋节距(screw distance): 270mm
3.螺旋轴转速(rotary speed of screw shaft): 10-85r/min
4.有效输送距离(effective conveying distance):≤1700mm
5.配用动力(supplement power): XWD5-17-4kw
6.输送能力(conveying capacity): ≤25m³/h
7.转速控制方式(control mode):变频调速frequency speed control

注:由于物料的松散密度及安息角随物料的水分、料度、输送速度等的不同而变化,应以实测为准。(最大输送倾角)本表仅供参考。
若输送倾角超过列表的β值,会因摩擦力不够物料在输送时将产生滑动。降低传送效率。
Note: For the density, inclination angle, moisture of material and conveying speed is different, so should refer to actual measurement If the inclination angle exceed the date in table B, material may slip down, because of friction not enough.

Structure and working principle

1.螺旋输送机由:1电动机2.减速机3.联轴器4.尾部支承5.排料口6.观察口7.上盖板8.合盖螺栓9.输送螺旋10.底架11.进料口12.头部支承
装置等组成。
Screw conveyor is composed of:
1, motor,2 speed reducer, 3,bearing device,4 tail supporting, 5, discharge opening, 6,observation port,7, upper board,8 screw bolt, 9 conveying screw 10, bottom struction,11 input opening, 12 head supporting.
2.有电动机输出动力至螺旋轴,随着螺旋叶片的轴向旋转,被输送
物料沿螺旋线方向作轴向移动,形成了物料的位移。
From power take off to the screw axis, material working with rotating direction of screw blade, so that formed material displacement.

四. 输送机的操作维护和保养
Operation and maintenance
1.输送机的安装和操作(installation and maintenance)
螺旋输送机据有结构简单、横截面积小、密封性能好,可以多点装料和卸料、操作安全等特点。设备安装时根据用户工艺联接要求,可以设置支座将螺旋输送机固定在楼板上或地坪上即可。
Screw conveyor, has a simple structure, small cross-sectional area, good sealing performance, and it can be more loading and unloading, safe operation features and so on. When installing the process according to the user connection requests, you can set bearings and…
