Replaceable membrane filter plates empty chamber multi
The empty chamber multi version of Klinkau's replaceable membrane filter plate is a development of the clip version and was designed for elastomer membranes. It has all the major benefits of the welded version. As for all Klinkau replaceable membrane filter plates, this product can also cope with squeezing into empty chambers.
Using a newly designed ring, the membrane is fixed to the plate by being interlocked at the sealed edges and at the staybosses. No other fixing is required. The design of the ring makes the membrane self-sealing. No other sealing is required. The filtrate, wash water and squeezing medium are then reliably kept apart during the entire filtration cycle.
Advantages of the replaceable membrane filter plate empty chamber multi
- Permits squeezing on empty or partially filled chambers
- No additional sealing required
- Interlocking clip system to prevent squeeze medium leakages even when opening the filter press
- CGR version (sealed
- Bigger pips at the sealed edges to improve filtrate efficiency
- Special pips at the stayboss chamfers areas to protect the filter cloth
- Variable choice of materials for high chemical resistance
|Sizes||1500 mm. Larger and alternative sizes available on request.|
|Feed eye position||Centralised feed. Other feed eye positions can be provided according to individual requirements.|
|Pressure||Standard products are suitable for maximum filtration pressures of 7 bar and maximum squeeze pressures of 16 bar. Plates also available for higher filtration and squeeze pressures.|
|Temperatures||The maximum permissible filtration temperature depends on factors such as filtration pressure, squeeze pressure, the chemical composition of the slurry to be filtered, cycle time and choice of filter material.|
|Materials||Membranes are available in the following materials: Polypropylene, modified polypropylene, PVDF as well as our own specially developed membrane material. A combination of different materials can be used for the membrane and membrane body plate.|
As in welded membrane filter plates, replaceable membrane filter plates also use membrane squeezing during the unproductive phase of pressure filtration. Filtering efficiency is therefore maintained throughout the filtration phase and filtration times are significantly reduced.
Klinkau's multi version of its replaceable membrane filter plates is based on the different functioning of the membrane and the membrane plate. The plate's function is to cope with the mechanical requirements of a chamber filter plate. It is designed to support the membrane during the filtration process. The plate has a pipped profile so the membrane does not lie completely flat to the plate. The membrane in the multi version is interlocked to the plate at the sealed edges and at the staybosses and fixed at inlet area with a steel O-ring. This enables easy and problem-free membrane replacement.
The filtrate drainage outlets are located only in the plate itself. The membrane is therefore suitable for filtration applications with or without cake washing. The specially designed sealed edges and staybosses prevent distortion or damage to the membrane when closing the filter press. The pips and drainage channels are designed to optimize drainage cake-wash efficiency and help to protect the filter cloth.
Klinkau membrane filter plates have two hinged lines that keep flex pressure to a minimum at the hinged areas during filtration and squeezing thereby extending the service life of the membranes. Squeezing into empty chambers is then possible without damaging the membrane.
