Agitated Nutsche Filters Manufacturer, Exporter
AGITATED NUTSCHE FILTER (ANF)
A Filtration Technique used in applications such as Dye, Paint, Pharmaceutical Production and Waste Water Treatment. Safety requirements and environmental concerns due to Solvent Evaporation led to the development of this type of filter wherein filtration under Vacuum or Pressure can be carried out in Closed Vessels and Solids can be discharged straightaway into a dryer.
FILTER FEATURES
A Typical Unit consists of a Dished Vessel with a Perforated Plate. The entire vessel can be kept at the desired temperature by using a Jacket and Stirrer (Blade and Shaft) through which heat transfer media can flow. The Vessel can be made completely leak-proof for Vacuum or Pressure service
AGITATOR
A Multipurpose Agitator is the unique feature of this system. The Agitator performs a number of operations through movement in axes both parallel and perpendicular to the shaft.
Process steps of agitated nutsche filter with agitator and discharge valve are
Agitator Assembly consists of Motor with VFD, Mechanical Seal is provided. Manual/Motorised System is provided for movement of agitator and discharge Valve. Control Panel with Motor control which will be installed in the safe area.
- Filtration
- Washing of Filter Cake
- Repeat mix or washing of the cake
- Convection drying of the cake
- Smoothing with compression of the cake
- Fully Automatic discharge of the wet or dried cake.
IMPORTANT POINTS
- Slurry contents can be kept liquidized using heat and agitation until most of the liquid is filtered through
- When filtration is complete, the cake develops cracks causing upsets in the vacuum operation. This hinders removal of mother liquor. The agitator can be used to maintain a uniform cake
- The cake can be washed after filtration by re-slurring the cake
- After washing, the mother liquor can be re-filtered. The cake can then be discharged by lowering the agitator and rotating it in such a manner that it brings all the cake towards the discharge port
ADVANTAGES
- Vacuum or Pressure Filtration possible
- Inert Gas Atmosphere can be maintained
- Minimal contamination of the cake
- Very high Solvent Recovery
- Considerable saving in manpower
- Solvents are in closed systems, so no toxic vapors are let off in the atmosphere
- Personal Safety is Maintained & Heat Transfer surfaces can be provided to maintain Filtration Temp
