螺旋输送机在输送形式上分为有轴螺旋输送机和无轴螺旋输送机两种,在外型上分为U型螺旋输送机和管式螺旋输送机。有轴螺旋输送机适用于无粘性的干粉物料和小颗粒物料.(例如:水泥、粉煤灰、石灰、粮等)而无轴螺旋输送机适合输送机由粘性的和易缠绕的物料。(例如:污泥、生物质、垃圾等)螺旋输送机的工作原理是旋转的螺旋叶片将物料推移而进行螺旋输送机输送,使物料不与螺旋输送机叶片一起旋转的力是物料自身重量和螺旋输送机机壳对物料的摩擦阻力。螺旋输送机旋转轴上焊的螺旋叶片,叶片的面型根据输送物料的不同有实体面型、带式面型、叶片面型等型式。螺旋输送机的螺旋轴在物料运动方向的终端有止推轴承以随物料给螺旋的轴向反力,在机长较长时,应加中间吊挂轴承。
Screw conveyor in the form of delivery is divided into two kinds of shaft screw conveyor and shaftless screw conveyor, in appearance is divided into U type screw conveyor and pipe screw conveyor. The axial screw conveyor is suitable for non - Sticky dry powder materials and small granular materials (e.g. cement, fly ash, lime, grain, etc.) and non - axis screw conveyor is suitable for the conveyor. (for example: garbage sludge, biomass, etc.) the working principle of screw conveyor is a rotating spiral blade passage for the material screw conveyor, the material and the spiral conveyor leaf rotation force is the friction of its own weight and screw conveyor casing material on the material. The screw conveyor rotating shaft welding spiral blade, blade face delivery of materials according to a solid surface with different type, belt type, leaf surface type etc.. The terminal in the direction of material movement of the screw shaft of the screw conveyor have thrust bearings with material to spiral axial force, the captain a long time, should be added the middle suspension bearing.
螺旋输送机从输送物料位移方向的角度划分,螺旋输送机分为水平式螺旋输送机和垂直式螺旋输送机两大类型。 螺旋输送机及其部件按输送链采用高强度塑料制作的螺旋输送机又称为食品螺旋输送机,螺旋提升机,主要适用于输送大件产品。如纸箱,周转箱,桶装水等。根据输送物料的特性要求和结构的不同,螺旋输送机有水平螺旋输送机、垂直螺旋输送机、可弯曲螺旋输送机、螺旋管(滚筒输送机)输送机。
The screw conveyor is divided into two types: horizontal screw conveyor and vertical screw conveyor. Screw conveyor and its parts are made of high strength plastic screw conveyor according to the conveyor chain, also known as food screw conveyor, spiral elevator, mainly for conveying large products. Such as carton box, turnover box, bottled water, etc.. According to the characteristics of the conveying material and the structure of the different requirements, the screw conveyor has a horizontal screw conveyor, vertical screw conveyor, flexible screw conveyor, spiral pipe (roller conveyor) conveyor.
(1)垂直螺旋输送机
(1) vertical screw conveyor
垂直螺旋输送机的螺旋体的转速比普通螺旋输送机的要高,加入的物料在离心力的作用下,与机壳间产生了摩擦力,该摩擦力阻止物料随螺旋叶片一起旋转并克服了物料下降的重力,从而实现了物料的垂直输送。该机输送量小,输送高度小,转速较高,能耗大。特别适宜输送流动性好的粉粒状物料,主要用于提升物料,提升高度一般不大于8米。
The spiral of vertical screw conveyor speed than ordinary screw conveyor must be high, effect of added material under the centrifugal force, the friction force and the casing, the friction material with helical blades rotate together to prevent and overcome the material decline in gravity, so as to realize the vertical transportation of materials. The machine has the advantages of small conveying capacity, small conveying height, high rotating speed and large energy consumption. It is especially suitable for conveying granular materials with good fluidity, which is mainly used for lifting materials, and the lifting height is generally not more than 8 meters.
(2)水平螺旋输送机
(2) horizontal screw conveyor
当物料加入固定的机槽内时,由于物料的重力及其与机槽间的摩擦力作用,堆积在机槽下部的物料不随螺旋体旋转,而只在旋转的螺旋叶片推动下向前移动,如同不旋转的螺母沿着转动的螺杆作平移运动一样,达到输送物料的目的。该机便于多点装料与卸料,输送过程中可同时完成混合、搅拌或冷却功能。对超载敏感,易堵塞;对物料有破碎损耗,水平螺旋输送机的结构简单,便于安装和维修以及故障处理。适用于水平或微倾斜(20o以下)连续均匀输送松散物料,工作环境温度为-20-+40℃,输送物料温度为-20-+80℃。其转速相对于垂直输送机要低,主要用于水平或小倾角输送物料,输送距离一般不大于70米。
When the material adding machine in the fixed groove, the friction material and the gravity trough, accumulation in the lower part of the slot machine material with rotating, but only in the rotating spiral blade driven by moving forward, as the rotation of the nut is not rotating screw for translational motion, and achieve the delivery the purpose of material. This machine is convenient for point loading and unloading, conveying process can be completed at the same time mixing, stirring or cooling function. The utility model has the advantages of high sensitivity, easy blockage, material loss, and simple structure of the horizontal screw conveyor. Suitable for horizontal or slightly inclined (20o below) uniform transmission of loose materials, the working environment temperature is -20-+40 degrees C, the material temperature is -20-+80 C. Its speed relative to the vertical conveyor is low, mainly used for horizontal or small angle transport materials, transport distance is generally not more than 70 meters.
(3)螺旋管(滚筒输送机)输送机
(3) spiral pipe (roller conveyor) conveyor
螺旋管输送机是在圆筒形机壳内焊有连续的螺旋叶片,机壳与螺旋叶片一起转动。加入的物料由于离心力和摩擦力的作用随机壳一起转动并被提升后,在物料的重力作用下又沿螺旋面下滑,使物料随螺旋管一起旋转从而实现了物料的向前移动,如同不旋转的螺杆沿着转动的螺母作平移运动一样,达到输送物料的目的。
The spiral pipe conveyor is welded with a continuous spiral blade in the cylindrical shell. Added material due to the centrifugal force and friction force of the random shell with rotation and be promoted, in the material under the gravity and along the spiral of decline, so that the material with the spiral pipe to rotate together to achieve forward movement of materials, like non rotating screw nut to rotate along the translational motion, to transport material the purpose of.
该机能耗低,维修费用低;在端部进料时,能适应不均匀进料要求,可同时完成输送搅拌混合等各种工艺要求,物料进入过多时也不会产生卡阻现象;便于多点装料与卸料,可输送温度较高的物料。适宜于水平输送高温物料;对高温、供料不均匀、有防破碎要求、防污染要求的物料和需多点加卸料的工艺有较好的适应性。实践证明,在输送水泥熟料、干燥的石灰石、磷矿石、钛铁矿粉、煤和矿渣等物料时效果良好。
This machine has low energy consumption, low maintenance cost; at the end of the feed, can adapt to uneven feeding requirements, can be completed at the same time conveying mixing various materials into too much technical requirements, does not produce jamming phenomenon; easy to point loading and unloading, but the material conveying high temperature. Suitable for conveying high temperature material to high level; and feeding is not uniform, anti crushing requirements, anti pollution requirements of material and to add the discharge process has better adaptability. Practice has proved that good effects in the transport of dry cement clinker, limestone, phosphate rock, titanium iron ore, coal and slag materials.
由端部进料口加入的物料,其粒度不能大于1/4的螺旋直径;自中间进料口加料的物料,其粒度均不得大于30毫米。为保证筒体不产生变形,加料温度必须控制在300℃以下。该机在输送磨琢性大的物料时对叶片和料槽的磨损极为严重。本次所设计的螺旋输送机主要用与输送硅微粉其磨琢性很大所以不适宜采用螺旋管输送机。
By the end of the feed inlet of the material, the particle size can not be greater than 1/4 of the diameter of the screw; from the middle of the feed material feeding, the particle size should not be greater than 30 mm. In order to ensure no deformation of the cylinder, the feeding temperature must be controlled below 300. The machine in the transportation of large mill cut material wear on the blade and the trough is extremely serious. The design of the screw conveyor is mainly used for conveying the silica abrasive so great is not suitable for spiral pipe conveyor.
(4)可弯曲螺旋输送机
(4) flexible screw conveyor
该机螺旋体心轴为可挠曲的,因此输送线路可根据需要按空间曲线布置。根据布置线路中水平及垂直(大倾角)段的长度比例不同,其工作原理按普通螺旋输送机或垂直螺旋输送机设计。
The spiral mandrel is flexible, so the transmission line can be arranged according to the space curve. According to the arrangement of the horizontal and vertical (large angle) of the length of the proportion of different, according to the working principle of ordinary screw conveyor or vertical screw conveyor design.
用于输送线路需要按空间曲线任意布置,避免物料转载的场合;当机壳内进入过多的物料或有硬块物料时,螺旋体会自由浮起,不会产生卡堵现象;噪音小。主要用于同时完成物料的水平和垂直输送。垂直输送时一般要求转速要高不能低于1000r/min。
For the transmission lines according to the spatial curve of arbitrary layout, avoid the material transfer occasion; when the casing into too many materials or hard materials, spiral experience to float freely, not blocking; low noise. The utility model is mainly used for the horizontal and vertical conveying of materials at the same time. The general requirements of the vertical transmission speed should not be less than 1000r/min.
