The working principle of the filter centrifuge and the selection points

The working principle of the filter centrifuge and the selection points There are various types of centrifuges, and the filter centrifuge is one of them
.

Maybe a lot of experimenters don't know much about their instruments.
The following editor will introduce you to the filter centrifuge and the working characteristics of the filter centrifuge.
Let's increase our knowledge together
.

A filter centrifuge refers to a centrifugal separator that uses centrifugal filtration to separate components in a suspension
.

There are many holes on the drum wall of the filter centrifuge, and the inner surface of the drum is covered with filter media
.

The suspension added to the drum rotates with the drum to generate a huge centrifugal pressure.
Under the action of the pressure, the liquid in the suspension flows through the filter medium and the holes on the drum wall and is thrown out, and the solid is trapped on the surface of the filter medium.
Separation of solids and liquids
.

The centrifugal force generated by the suspension in the drum is thousands of times that of gravity, which intensifies the filtration process and speeds up the filtration rate
.

The working principle of the filter centrifuge is mainly to centrifugally press the mixture onto the filter screen wall
.

The liquid flows out through many small filter holes on the drum wall.
Due to the large particles, the solids are retained by the filter screen
.

As the centrifugation time increases, more and more solids build up in the drum filter
.

When the requirements are met, stop the machine, take out the solid for observation, and recover the liquid if needed
.

How to choose a filter centrifuge: The choice of a centrifuge must be based on the size and concentration of solid particles in the suspension (or emulsion), the density difference between solid and liquid (or two liquids), the viscosity of the liquid, and the density of the filter residue (or sediment).
The characteristics and separation requirements are comprehensively analyzed to meet the requirements for the moisture content of the filter residue (sediment) and the clarity of the filtrate (separate liquid), and which type of centrifugal separator to use is initially selected
.

Then determine the type and specification of the centrifuge according to the processing capacity and the automation requirements of the operation.
Generally, for the suspension containing particles with a particle size greater than 0.
01 mm, a filter centrifuge can generally be used; for the particles in the suspension are fine or compressible, the The decanter centrifuge should be used; the separator should be used when the suspension contains low solid content, small particles and high requirements for liquid clarity
.

How to separate solid-liquid mixing or solid-liquid-liquid mixing: The main equipment used is centrifugal separator (also called filter centrifuge, centrifugal filter separator).
When the centrifuge is driven, the circular motion of the drum drives the centrifugal acceleration of the raw material slurry.
The molecular weight, density, size and shape of the different components of the mixed components are different from each other, and the sedimentation velocity in the centrifugal force field of the same fixed size is also different, so that they can be separated from each other, so the separation can be achieved.

 The above is the relevant introduction about the working principle of the filter centrifuge.
I believe that everyone has a corresponding understanding of this after reading it.
After understanding the relevant matters, you can choose and use it to achieve the separation of solids and liquids.
I hope it can help everyone
