PFE - Pressure Belt Filter Multiple Fields of Application Industrial painting pre treatment area -                 filtration of degreaser bath                 filtration of iron phosphate bathes                 filtration of zinc phosphate bathes painting area -                 dewatering of paint sludge    Machine tools - filtration of coolant for machining application with and without chip generation, especially for grinding machines - designs for the coolant supply of single machine tools and machine tool groups    Food industry - diatomaceous earth dewatering in sugar refining filtration - recovery of corn out of rinse bathes in corn mills      Beverage industry - production of fruit juice - diatomaceous earth dewatering in breweries           Galvanising industry - filtration of galvanic and chemical electrolytes - filtration of corrosive solutions          Pharmaceutical industry - solid/ liquid separation and dewatering of pre products          chemical industry - filtration of acids, lies and solvents - dewatering of iron oxide          Power plants - gypsum (plaster) dewatering at desulphuriation systems         Foundries - filtration of the wash water used in wet scrubbers       Advantages              attendance-free, fully automatic operation over 24 hours per day      high filtration quality due to adjusted high filtration pressure     high cake dryness due to multi stage drying system   high process-/ and operation safety even by lost of air pressure    - low energy-, operation- and maintenace costs     direct filtration, no tilled plate seperators are required (specially. phosphating bathes)    high specific flow rates due to optimised flow conditions        self adjusting closing mechanism without mechanical attachment      easy installation, start up and system integration      equal cake build up due to horizontal arrangement of filter surface      high availability due to very low unproductive down times      inline design, the media that has to be filtered can be pumped through the filter back to the bath      chamber seals on the perimeter of the chamber seal the filter surface to the atmosphere and to the filtrate side, this guarantees a clean filtration plant and highest filtrate quality     PLC control with integrated trouble diagnostic and connection or signal exchange to an overriding PLC belongs to the standard equipment. The PLC offers the possibility to control other components in the periphery of the filter                       FILTRATION SEQUENCE: The filter chambers (1 and 2) are closed by raising the lower filter chamber (2). Chamber seals (3) on the perimeter of the filter chambers create tight sealing of the filter surface. Solid bearing liquid will be pumped by the filter pump (4) into the upper filter chamber (1). The liquid is forced through the filter media (5), which is supported by a perforated screen in the lower filter chamber. The solids will be collected on the filter media and will be formed to a filter cake. The filtrate flows through the lower filter chamber and will be forced back to the bath.   DRYING SEQUENCE: The drying of the filter cake succeeds after reaching the maximum admissible differential pressure, or the preadjusted time limit. The liquid inlet valve (6) will be closed, the air supply valve (7) will be opened and the cake will be dried now by the incoming pressurised air. After reaching a preadjusted pressure limit and / or a preadjusted time limit, the drying sequence is finished.   REGENERATION SEQUENCE: After the lower filter chamber has moves down, the gear motor (8) will move the filter media with the filter cake. The filter cake separates from the filter media and drops into a container (9). After the filter surface is covered by fresh filter media, a new filtration sequence starts.
