SISMAT - Chamber Plate Filter Presses
Sismat can supply filterpresses in sizes from 250 x 250 mm up to 1500 x 1500 mm for a range of filtration pressures 3-16 bars and consist of modular components. The torsion resistant basic design of our filterpresses comprising plate, cloth and support frame can be built up into a fully automated unit by utilizing the various system options.
The basic structure of filterpresses consisting of fixed head plate, moving end plate, side bars, hydraulic opening-closing device, set of plates, and set of filter cloths can be extended by the addition of optional accessories for easy and safe operation.
Any of the features mentioned below can be added onto a basic press to modify it to a later model. The design of these individual parts is matched to provide practical and economical use of the whole unit. Thus, for example, very short cake cleaning times can be achieved by using the rapid cycle of the automatic plate shifting system and high speed return of the hydraulic unit.
Plate Opening and Cake Discharge Systems
We can offer several different plate opening methods either for one by one or full pack separation at once. Plate tilting is available for easily falling (non-sticky) cakes.
For a safe operation, all the moving parts are protected by guard panels. Further alternating precaution equipment are light curtains to stop the filterpress operation when something or somebody comes into its operation field, a sliding window used in filterpresses complete with washing device as well to prevent water splashes and safety system with ropes.
Furthermore a mobile overhead control button which accompanies the system so as to be always located at the point of activity contains emergency stop and restart switches.
Compressed Air Distribution System
Compressed air is used for the purposes of inflating the membranes or clearing the feeding hole.
Additionally, the end plate could be equipped with a core blowing system to discharge the sludge out of the feeding hole back through the head plate
It is placed below the filterpress as discharge flaps in two pieces that are hydraulically or motor driven downwards. It is used for the purpose of collecting both washwater and droplets that occur during filtration. Two filtrate trays located on both sides of the filterpress collect the water directed by the drip tray
We offer alternative solutions for cake transportation, e.g. belt or screw or pallet conveyors and big bag frames
Programmable Logic Control (PLC)
PLC is a switch cabinet equipped with an operating panel that sends the required no of outputs on a LCD-display and an integrated operating keyboard. The cabinet is completely wired, ready for connection and mounting onto the filterpress. Auxiliary equipment can be integrated into the PLC-system to run an automated process operation.
Filter Cloth Washing Unit
The unit will be positioned by proximity switches and the spray pipe starts cleaning process from the top between two filter plates. Possible tolerances will be levelled with magnetic sensors installed at the spray pipe. The unit is fully integrated into the PLC and runs automatically
Pre-fabricated Operation Buildings
Sismat offers complete turn-key dewatering plants
Water Splash Protection
Filterpress can be designed as a closed unit covered by sliding windows both for the prevention of wash water splashes and for safety reasons. Windows are controlled by sensors that stop the press when they are opened.
