From Filter Presses
In addition to its simple and inexpensive design, the chamber filter press is also a powerful and reliable filter press. The type of suspension to be filtered (e.g. mining, chemical or pharmaceutical industry) is irrelevant. In order to meet the different requirements of industry and municipalities, MSE chamber filter presses are designed for this in modular design. The solid and heavy-duty steel filter press frame, which consists of the following main components, forms the basis: Feeding stands with filtrate outlet (head piece), hydraulic stands with locking cylinder (pressure piece), cross beam and side rails on which the individual filter plates are arranged accordingly including filter cloths. The plate pack also consists of uniform chamber plates with a cut-out of 15-50 mm for holding the puncture-proof filter cake. Polypropylene (PP) is used as the chamber plate material in the standard version.
High Performance And High Degree Of Configuration For Your Chamber Filter Press
The chamber filter press can be configured as required depending on the series. These include, for example, automatic plate shifting, a vibrating device or core blow-out and/or core rinsing. Taking different influencing factors into account, chamber filter presses achieve a solids content in the filter cake from 30 to over 50 percent. The intelligent filtration principle leads to immense cost savings in the waste water sector, for example. The operation of the chamber filter press is designed for a feed pressure of up to 30 bar in order to successfully filter even the finest particles.
At the beginning of the filtration cycle, the press and the filter plates are closed by a (hydraulic) locking cylinder. The closing cylinder presses the filter plates against each other via the pressure plate and increases the hydraulic pressure accordingly up to the required nominal closing pressure. Due to the design, a chamber is formed between the individual filter plates, which represents the process chamber. The suspension to be filtered is pumped into the chambers with a suitable feed pump through the turbidity inlet at the feed stand and concentrated there. Depending on the respective application, the filter plates are lined with special filter cloths which visibly retain the solids during the flow, taking into account the process characteristics.
Discharge Of The Filtrate / Emptying Of The Chambers
The filtered and clear liquid (filtrate) is discharged along a channel system (open filtrate outlet) into the laterally mounted filtrate channel. A closed filtrate outlet is also available as an option. The solid material, on the other hand, remains in the plate chamber as a solid filter cake. The increasing feed pressure compresses and dewaters the resulting filter cake in the chamber. Once the throughput has fallen to a predetermined minimum, the pressure has increased significantly and the individual chambers inside the filter plates are completely filled with the filter cake, the filtration process is complete. To empty the chambers, the closing pressure of the filter press is released, the filter press is opened and the cake is removed from the filter cloths. The filtration cycle is then repeated.
