Product Description

Chamber Filter Press is a kind of intermittent operation of the filter equipment, by the material pump will be suspended liquid into the filter chamber in the machine to form pressure filtration, mainly used in coal washing plant, cleaned coal, tail coal recovery, also can be used in petroleum, chemical, dye, pharmaceutical and other industries.


The Chamber filter press is the most common filter press used in chamber filter plates. Filtering occurs in the space formed between two adjacent plates. The volume of the filter depends on the depth of the chambers. Chamber plates are generally made from high-strength polypropylene and have high performance. Chamber filter presses are used in cases if the process requires only mechanical separation of the slurry and does not need the low moisture content of the sludge. An example is the filtering of sewage sludge, electroplatings wastes after neutralization, and ceramic slip.


Membrane filter presses reduce the filtration cycle to produce a highly efficient washing and drying of the residue, without unloading it from the filter, to achieve a low moisture content of the sludge. The process of filtration in the membrane filter press is similar to the chamber. But the fundamental difference is the fact that when filling the chambers with sediment, it is not unloaded immediately. Further, it is pressed under the action of fluid supplied under the membrane. The possibility for squeezing appears due to the membrane plates. The use of membranes for the mechanical squeezing of sediment can significantly reduce the time of one cycle and enhance the daily performance of the filter press.


Chamber Filter Press


In addition to its simple and inexpensive design, the chamber filter press is also robust and reliable.  The type of suspension to be filtered (e.g., mining, chemical or pharmaceutical industry) is irrelevant. To meet the different requirements of industry and municipalities, 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 (headpiece), hydraulic stands with locking cylinder (pressure piece), crossbeam, 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 15-50 mm cut-out 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 core rinsing. Considering different influencing factors, chamber filter presses achieve a solids content in the filter cake from 30 to over 50 percent. For example, the intelligent filtration principle leads to immense cost savings in the wastewater sector. The operation of the chamber filter press is designed for a feed pressure of up to 30 bar to filter even the finest particles successfully.

Filtration Principle

How does a filter press work?

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 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, considering the process characteristics.

Discharge / Emptying

Discharge Of The Filtrate / Emptying Of The Chambers

The filtered and clear liquid (filtrate) is discharged along with a channel system (open filtrate outlet) into the laterally mounted filtrate channel. A closed filtrate outlet is also available as an option. On the other hand, the solid material remains in the plating chamber as a solid filter cake. The increasing feed pressure compresses and dewaters the resulting filter cake in the chamber. The pressure has increased significantly once the throughput has fallen to a predetermined minimum. The individual chambers inside the filter plates are filled with the filter cake, and 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.
