Agitated Nutsche Filter

Magtech Process Equipments Pvt Ltd highly trained & rich experience professionals engaged in offering Agitated Nutsche Filter. It provides an economic operation where maximum percentage of liquid in a slurry is separated through mechanical means. The remaining little moisture can be removed by evaporation to obtain dry products. It consists of a cylindrical shell with welded dished end at the top and either a flanged and bolted dished end or a welded dished end / flat welded end at the bottom depending on process/customer’s requirements. The vessel is divided into two compartments by means of a perforated plate, provided with suitable filter cloth or porous tiles. An agitator of unique design is provided inside the vessel. This agitator can perform multifarious activities by manipulating its movement of vertical and rotational directions simultaneously, by push buttons switches/PLC. The filter is capable of operating under either pressure or vacuum or a combination of both.

Operation

Slurry is feed into the top compartment from where filtrate passes into the lower chamber en route to receiver. Solids are deposited on the filtering media in the top compartment and take the shape of cake of a uniform thickness. The agitator pushes the solid content in the slurry upwards by keeping it under suspension till maximum possible filtrate passes through the filter bed. This reduces time and increase productivity. It then seals the cracks in the cake, which develop after most of the filtrate has passed through, by smoothening the top surface of the cake. It also squeezes out some of the moisture in the cake by slightly pressing the cake uniformly with the help of specially designed blades. After the initial solvent/mother liquor has been separated, sometimes it is necessary to wash the cake. The Agitator has been designed in such a way that after adding wash liquor on the cake, the entire cake can be re-slurred and agitated, so that all the particles forming the cake can be exposed to wash liquor and be thoroughly washed. This improves the quality of the finished products. After washing and removal of wash liquor, the cake can be discharged through a quick opening side discharge door, by rotating and lowering agitator in the discharge direction. No manual handling is required.
