螺旋輸送機的分類

螺旋輸送機從輸送物料位移方向的角度劃分，螺旋輸送機分為水平式螺旋輸送機和垂直式螺旋輸送機兩大類型。

按輸送鏈采用高強度塑料制作的螺旋輸送機又稱為食品螺旋輸送機，螺旋提升機，主要適用于輸送大件產(chǎn)品。如紙箱，周轉(zhuǎn)箱，桶裝水等。
根據(jù)輸送物料的特性要求和結(jié)構(gòu)的不同，螺旋輸送機有水平螺旋輸送機、垂直螺旋輸送機、可彎曲螺旋輸送機、螺旋管（滾筒輸送機）輸送機。
（1）垂直螺旋輸送機
垂直螺旋輸送機的螺旋體的轉(zhuǎn)速比普通螺旋輸送機的要高，加入的物料在離心力的作用下，與機殼間產(chǎn)生了摩擦力，該摩擦力阻止物料隨螺旋葉片一起旋轉(zhuǎn)并克服了物料下降的重力，從而實現(xiàn)了物料的垂直輸送。該機輸送量小，輸送高度小，轉(zhuǎn)速較高，能耗大。特別適宜輸送流動性好的粉粒狀物料,主要用于提升物料，提升高度一般不大于8米。
（2）水平螺旋輸送機
當物料加入固定的機槽內(nèi)時，由于物料的重力及其與機槽間的摩擦力作用，堆積在機槽下部的物料不隨螺旋體旋轉(zhuǎn)，而只在旋轉(zhuǎn)的螺旋葉片推動下向前移動，如同不旋轉(zhuǎn)的螺母沿著轉(zhuǎn)動的螺桿作平移運動一樣，達到輸送物料的目的。該機便于多點裝料與卸料，輸送過程中可同時完成混合、攪拌或冷卻功能。對超載敏感，易堵塞；對物料有破碎損耗，水平螺旋輸送機的結(jié)構(gòu)簡單，便于安裝和維修以及故障處理。適用于水平或微傾斜（20º以下）連續(xù)均勻輸送松散物料，工作環(huán)境溫度為-20—+40℃，輸送物料溫度為-20—+80℃。其轉(zhuǎn)速相對于垂直輸送機要低，主要用于水平或小傾角輸送物料，輸送距離一般不大于70米。
（3）螺旋管（滾筒輸送機）輸送機
螺旋管輸送機是在圓筒形機殼內(nèi)焊有連續(xù)的螺旋葉片，機殼與螺旋葉片一起轉(zhuǎn)動。加入的物料由于離心力和摩擦力的作用隨機殼一起轉(zhuǎn)動并被提升后，在物料的重力作用下又沿螺旋面下滑，使物料隨螺旋管一起旋轉(zhuǎn)從而實現(xiàn)了物料的向前移動，如同不旋轉(zhuǎn)的螺桿沿著轉(zhuǎn)動的螺母作平移運動一樣，達到輸送物料的目的。
該機能耗低，維修費用低；在端部進料時，能適應不均勻進料要求，可同時完成輸送攪拌混合等各種工藝要求，物料進入過多時也不會產(chǎn)生卡阻現(xiàn)象；便于多點裝料與卸料，可輸送溫度較高的物料。適宜于水平輸送高溫物料；對高溫、供料不均勻、有防破碎要求、防污染要求的物料和需多點加卸料的工藝有較好的適應性。實踐證明，在輸送水泥熟料、干燥的石灰石、磷礦石、鈦鐵礦粉、煤和礦渣等物料時效果良好。
由端部進料口加入的物料，其粒度不能大于1/4的螺旋直徑；自中間進料口加料的物料，其粒度均不得大于30毫米。為保證筒體不產(chǎn)生變形，加料溫度必須控制在300℃以下。該機在輸送磨琢性大的物料時對葉片和料槽的磨損極為嚴重。本次所設計的螺旋輸送機主要用與輸送硅微粉其磨琢性很大所以不適宜采用螺旋管輸送機。
（4）可彎曲螺旋輸送機
該機螺旋體心軸為可撓曲的，因此輸送線路可根據(jù)需要按空間曲線布置。根據(jù)布置線路中水平及垂直（大傾角）段的長度比例不同，其工作原理按普通螺旋輸送機或垂直螺旋輸送機設計。
用于輸送線路需要按空間曲線任意布置，避免物料轉(zhuǎn)載的場合；當機殼內(nèi)進入過多的物料或有硬塊物料時，螺旋體會自由浮起，不會產(chǎn)生卡堵現(xiàn)象；噪音小。主要用于同時完成物料的水平和垂直輸送。垂直輸送時一般要求轉(zhuǎn)速要高不能低于1000r/min。

螺旋輸送機工作原理

當螺旋軸轉(zhuǎn)動時，由于物料的重力及其與槽體壁所產(chǎn)生的摩擦力，使物料只能在葉片的推送下沿著輸送機的槽底向前移動，其情況好像不能旋轉(zhuǎn)的螺母沿著旋轉(zhuǎn)的螺桿作平移運動一樣。物料在中間軸承的運移，則是依靠后面前進著的物料的推力。所以，物料在輸送機中的運送，完全是一種滑移運動。為了使螺旋軸處于較為有利的受拉狀態(tài)，一般都將驅(qū)動裝置和卸料口安放在輸送機的同一端，而把進料口盡量放在另一端的尾部附近。 旋轉(zhuǎn)的螺旋葉片將物料推移而進行輸送，使物料不與螺旋輸送機葉片一起旋轉(zhuǎn)的力是物料自身重量和螺旋輸送機機殼對物料的摩擦阻力。葉片的面型根據(jù)輸送物料的不同有實體面型、帶式面型、葉片面型等型式。螺旋輸送機的螺旋軸在物料運動方向的終端有止推軸承以隨物料給螺旋的軸向反力，在機長較長時，應加中間吊掛軸承。
Working principle
When the screw axis rotation, due to the gravity of the material and the tank wall solutions generated by friction, make the material only under the push of blade groove bottom along the conveyor moving forward, the situation can't seem to rotate the nut along the rotation of the screw for translational motion.Material bearing in the middle of the migration, it is depend on the materials go forward thrust behind.So, the material of the conveyor transport, completely is a kind of sliding motion.In order to make the screw axis in a favourable state of tension, the general will drive and with the end of the discharging mouth on the conveyor, and near to the end of the feeding port on the other side as far as possible.Rotating spiral blade for conveying the material goes on, the material is not spinning force with the blades of screw conveyor is its own weight and screw conveyor casing material friction resistance of the material.Blade surface type according to the conveying material has the entity type, belt type, leaf surface type and model.Screw conveyor screw axis of the terminal at the direction of material movement have thrust bearings to the material to spiral axial reaction force, the captain is longer, should add hanging bearing in the middle.
