Pressure Agitated Nutsche Filter Dryer Washing And Drying Machine
With Insulation
Process steps
1 . Feeding
Open the feeding valve to feed in the tank, paddle should be in the
upper position when feeding, if necessary, can be lowered stirring
paddle for low speed stirring, so that the material is evenly
distributed. When the material reaches the specified process stop
feeding, close the feed valve
2 . Washing
Washing fluid at 0.2 ~ 0.3MPa pressure by the rotating nozzle cleaning, and stirring paddle has been suspended high.
Slurry washing: When a certain amount of washing liquid after the
accession to stop adding gradually lower stirring paddle and pulp
slurry at an appropriate speed stirring. Stir continuously from top
to bottom.
3 . Filter
After washing, upper the stirrer to related position, stop
stirring, the liquid will be discharged from bottom. Then repeat
the filtering steps until you get perfect material.
If filter finish,make the material is similiar, then make the
stirrer blade upper from material surface about 20mm.
4 . Drying
a . open hot water valve, then balance valve, nextly vacuum valve.
b . Pls open the balance valve in advance if upper vacuum down drying
condition, to ensure pressure balance. to Concentration of chloride
ions in the heating and cooling water should be strictly
controlled, to avoid chloride ions on the jacket and the tank
corrosion. Pls use of chloride-free water.
c . Open the jacket water inlet valve slowly, and open slightly for
water outlet valve. Fully open them when outlet and inlet has
temperature gap less than 20℃ to avoid cavitation vibration.
5 . Material discharge
Sampling analysis before discharge, if ok, then discharge them.
First turn off the heating water valve, slowly open the cooling water valve. Slowly lower the stirring paddle, stirring material accelerated
cooling, then the vacuum pump can be opened to exhaust heat.
Before open the discharge valve, pls fill pure nitrogen for balance protection. when the pressure is atmospheric pressure, the impeller through the
thrust reverser action, the material discharged from the discharge
valve.
Description
In order to meet the confined production process, filtering washing machine, two -in-one filter has been developed. This production system can realize half automatic or complete automatic operation control.
Maily used for crystallization liquid filtration, washing, drying
process. It includes: feeding, beating, filtering, washing, discharging, on-line
inspection (optional), etc key steps to prepare for the cleanroom of next mixing process. Besides this Nutsche Filter Dryer also has CIP, SIP functions.
Application
It could be used in various field such as fine chemical, petroleum,
printing, foodstuff and pharmaceutical industries and so on.
Nutsche filter dryer are widely used for critical high purity
separations of liquids and solids, and now being used in the cbd
oil industry.
It is widely used for final step of cbd oil purity process. With
pur critical operation as final step, the cbd crystalizing
isolation can reach above 98%.
