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:
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 .
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 .
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 .
