ROTARY FILTER

Full-Automatic Continuous Pressurised Filter


Overview

In general, continuous operation of the pressurized filter is difficult, the large space requirement is also a problem.
The "KOTOBUKI Rotary Filter" is a unique automatic pressurized continuous filter adopting the principle of dynamic filtration which have made a break-through in materializing the automatic continuous operation.
The Rotary Filter involves two technically important points, that is, the agitating effect and cake discharging valve control method.  The following features have been brought out utilizing these functions.



Benefits
1. It's an automatic continuous operation
Dismantling operations are not necessary thanks to the automatic continuous cake discharge and automatic back flashing.
2. Processing capacity is excellent
Processing quantity per unit area is extremely large compared with other models.
3. Mother liquid replacing rinsing is possible
Rinsing of high replacing rate (diluting rate) is attainable with a limited amount of rinsing liquid.
4. Concentration control is easy
Precision control of the cake concentration adapted to the subsequent processes can be performed easily.
5. Filtrate is clear
Sub-micron particles are completely caught by the selection of filtering media.  After the permanent cake layer is formed on the filter cloth, cake itself functions as a filter resulting in the improvement in the cleanliness.
6. A compact system
The equipment is extremely light and compact compared with its processing capacity, thereby requiring no large-scale foundation when installing.
7. Comfortable Working Environment
Filtration of acid, alkali and other toxic substances can be carried out safely owing to the complete hermetic configuration.  Also free from troublesome noise and vibration.

Applications
 
Dewatering of iron oxide and ferrite
Thickening/dewatering of food additive
Rinsing/dewatering of slurry for electronic materials
Dewatering of nuclear power laundry drainage
Removal of suspended solid from the processing liquid of the aluminum foils for capacitors
Rinsing/dewatering of rare-earth element
