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。

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 .

結構及原理
三足式下部卸料離心機以轉鼓為主件，將刮刀趨動、機械傳動、機殼等功能部件模塊化設計，使之可以實現多功能任意組合。
刮刀趨動方式：液壓、氣動、電動、手動。
啟動方式：變頻器、離合器。
剎車方式：變頻制動單元、手動閘瓦。
外殼：大翻蓋、半翻蓋，密閉蓋。
電動機趨動皮帶輪由導靜電阻燃窄V帶帶動主軸系統旋轉，使鑄不鏽鋼材質的轉鼓同步旋轉。物料通過加料管從轉鼓側壁加入。
在離心力場的作用下，料液被拋向轉鼓壁。液相濾網、鼓壁孔進入機殼空間，落到機殼底盤上，經出液口排出，固相物留在濾網內側。料層厚度由專門的料位探測器控制，加料和洗滌均由專門的進料閥控制，脫水完畢后，轉鼓降速，刮料器將固相物料刮落下來，經轉鼓底上的出料口卸出。
主要用途
廣氾應用於固相為顆粒狀懸浮液的過濾。
化學工業：石膏、乙二酸。
食品工業：味精、食品添加劑。
製藥：維生素、抗生素。
礦冶：銅、鋅、鋁、礦產物、金屬精製。
環保：淨水污泥、下水污泥。

技術參數
Filtering upper discharge centrifuge
工作原理
電機帶動離合器由三角膠帶將動力傳遞給轉鼓、使轉鼓繞自身軸線高速迴轉，形成離心力場。物料從頂部料管進入轉鼓內的離心力場中，離心力迫使物料均布在轉鼓壁上進行脫液分離，液相透過固相物料和濾網縫隙，經鼓壁孔甩至機殼空間，從機身底盤出液口排出。固相物料截留在轉鼓內，停機后人工上部卸出。
與物料接觸部分可選用耐蝕鋼，標記為：SSX XX-N，普碳鋼、標記為：SSXXX－G，碳鋼搪橡膠，標記為：SSXXX-J，鈦合金，標記為：SSXXX-T。轉鼓可以製成無孔型式的沉降型、為沉降式離心機，標記為：SSCXXX。技術參數與相應的SS 型過濾式基本相同。

技術參數
Punching bag centrifuge
工作原理
主電機由變頻調速器控制，平穩啟動，通過三角帶將動力傳遞給轉鼓，使其繞自身軸線高速旋轉，形成離心力場，物料由上部加料管進入襯有濾袋的轉鼓內，離心力迫使物料均布在轉鼓上，進行離心過濾，液體穿過濾袋縫隙和鼓壁小孔甩至外殼空腔，由排液口排出，固體物料截留在濾袋內，停機后，開啟機蓋，吊出機外到放料地點卸料;配有洗滌管，可以對物料進行洗滌。
主要特點
啟動平穩，分離因素可調，全密閉防爆，勞動強度低，工效高，環境衛生狀況完全符合GMP的標準。
技術參數
Decenter upper discharge centrifuge
特點及用途
沉降型離心機適用於固相含量較少且固相顆粒微小的懸浮液的分離。其分離因數略高于過濾型離心機。可用於分離過濾型離心機難以分離的物料。可以應用在管式高速離心機的前道工序，將物料固相物大部份分離出。
工作原理
在離心力的作用下，固相物料與液相物料形成內外兩個環形物料層。內層的液相物料隨時由撇液管導出，外層為固相物，沉積于轉鼓壁，停機後人工卸出，達到固液分離的目的。
