Three-column separator
Three-column bottom auto-discharge centrifuge, known as three centrifuge, because the bottom of the support legs for the three columns, arranged in a triangle with equal portions named. Centrifuge is a three-column solid-liquid separation equipment, mainly in the solid liquid separation to remove liquids or solids separate.
Tripod is the most versatile centrifuge centrifuge, starting from the first centrifuges, used in all walks of life, has yao still popular worldwide, and its low cost, resistance to shock, simple structure, easy to operate.
As the general three-foot low speed centrifuge, separation accuracy is not high, we usually draw it as a coarse type equipment regulations for the handling of large amount of solid, clear liquid clarity less demand.

way of separator
Two ways to separate :
1.Filtering : There is holes in the rolling drums .Its widely used for some conditions ,such as less viscosity ,solid big granular ( crystalline ) ,mostly used to dewater .
2.Decanter :Closed rolling drums to separate solid and liquid through centrifugal force .Its used widely ,such as big viscosit ,small granular both can be separted .
Working principle
the material from the top to join the drum under the action of the centrifugal force field, the liquid spreads through the wall of the drum filter into the filter body floor chassis, a liquid outlet from the discharge, and solid materials retained in the drum, removable by hand from the top of the centrifuge from the electrical control, two-speed motor. Can automatically complete a work cycle. That is, start a slow start a high-speed running an electric brake. Can also be used with inverter。

feature
It has wide function which widely used in all kinds of industry .It is still used in the world with low cost ,strong antiknock ,simple structure ,easy opeation .
Common stoppage and troubleshoot
1.big noise
Possible reason: bad level destroiedshock mitigation system ;not stable load speed ,rolling drum is eroded for long time ; less lubricant at friction part; jam of inlet
Troubleshoot ：To check if centrifuge is put levelly ;load equally ,the right procedure to to load is to start up machine first to full speed ,then load with small quantity to big evenly ;check solid and liquid mixed well ;check if sticky dry stuff on rolling drum ;add lubricant on rotor bearing ;check if inlet is blocked .
2. high temperature on main bearing
Possible reason: no lubricant on main bearing,;tiny stuff between main bearing ;run high speed
Troubleshoot :open main bearing to add lubricant ,clean main bearing ;use compatible centrifuge .
3.high temperature on dynamo
Possible reason: heavy burdn ;high speed of dynamo ; circuit deisgn default .
Troubleshoot: make sure if the machine run under relevant load and dynamo runs at normal speed .If all is ok ,but temperature is still very high ,please contact supplier to change it .
Centrigue is a high-speed running machinese .Normally the processing materials are corrosive .We need to check to make sure all parts are running well and to change new one if necessary during long time operating .
filter procedure
The working theory is intermittent filter ,contains 5 procedures:
１ load
After stuff is loaded in rolling drum by horizontal loading pipe ,mother solution is thrown off from rolling drum and become filter cake .The best filter cake can be obtained by frequent loading at low -speed condition to ensure the initial filter cake and less loss of load .
２ dry initial dry
Mother solution needs to be thrown off from rolling drum after loading .Operator can control speed of rolling drum revolution (high speed ) ,this is the initial drying .
３ wash
Filter cake needs to be washed by one or many cleaning mixture after mother solution is thrown off filter cake .Cleaning mixture is tranported into rolling drum by loading pipe and scattered by studdle to make even liquid co
4 dry
washing ,then dry filter cake .
5 discharge
At last adjust rolling drum speed to discharge speed ,the flat part of rolling drum is pushed up ,filter cake is discharged automatically . The filter bag is turned over toally ,filter cake is thrown off from it .The solid will slide into next procedure ,such as drier ,load barrel .One cycle is over after discharge ,the flat part of rolling drum will be pushed back rolling drum to start a new circle .

结构及原理
三足式下部卸料离心机以转鼓为主件，将刮刀趋动、机械传动、机壳等功能部件模块化设计，使之可以实现多功能任意组合。
刮刀趋动方式：液压、气动、电动、手动。
启动方式：变频器、离合器。
刹车方式：变频制动单元、手动闸瓦。
外壳：大翻盖、半翻盖，密闭盖。
电动机趋动皮带轮由导静电阻燃窄V带带动主轴系统旋转，使铸不锈钢材质的转鼓同步旋转。物料通过加料管从转鼓侧壁加入。
在离心力场的作用下，料液被抛向转鼓壁。液相滤网、鼓壁孔进入机壳空间，落到机壳底盘上，经出液口排出，固相物留在滤网内侧。料层厚度由专门的料位探测器控制，加料和洗涤均由专门的进料阀控制，脱水完毕后，转鼓降速，刮料器将固相物料刮落下来，经转鼓底上的出料口卸出。
主要用途
广泛应用于固相为颗粒状悬浮液的过滤。
化学工业：石膏、乙二酸。
食品工业：味精、食品添加剂。

技术参数
Decenter upper discharge centrifuge
特点及用途
沉降型离心机适用于固相含量较少且固相颗粒微小的悬浮液的分离。其分离因数略高于过滤型离心机。可用于分离过滤型离心机难以分离的物料。可以应用在管式高速离心机的前道工序，将物料固相物大部份分离出。
工作原理
在离心力的作用下，固相物料与液相物料形成内外两个环形物料层。内层的液相物料随时由撇液管导出，外层为固相物，沉积于转鼓壁，停机后人工卸出，达到固液分离的目的。
