Filter-press technical description

Filter-press consists of a set of horizontal filter plates placed between thrust and pressure plates. Hydraulic clamping device with V-fixing that performs rising, sealing and lowering of filtering plates set is mounted on the thrust plate. Filter-press thrust and pressure plate are connected by tie rods. Filter cloth in the form of endless belt is stretched in a zigzag manner between the filter plates. The filter cloth is moved by cloth moving drive with driving and pressure rollers in order to discharge sediment and its regeneration. Driving roller is actuated from electric motor through V-belt transmission and gearbox. Irrigation tubes for cloth spray washing and cloth cleaning knives (scrapers) are installed in the regeneration chamber. Cloth is tensioned by tension device fixed on the cloth moving drive and thrust plate. Chains and cloth tension device fastened on them are driven by hydraulic motor.

Cloth adjustment roller is designed to eliminate any displacement of filter cloth relative to filter plates. Pressure plate, tray, regeneration chamber and cloth moving drive are mounted on a common frame. Water supply collector for diaphragm is set on one of the tie rods.

Filter plate consists of two parts: upper part — casing (of filtrate chamber) and lower part — frames (filter chambers).

The filter — press housing is designed for filtrate collection and discharge and it has a bottom, side walls and drain bottom in the form of separate inserts. The frame works as a filtration chamber where sediment is formed and dried. Between the casing and the frame is a rubber diaphragm, designed for sediment extraction (pressing) Clamping device clamps a set of plates and seals the filter chambers. When compressing filter — press plates a suspension is supplied under pressure to the bottom of each plate — the filter chamber. The liquid phase passes through the cloth and drain base and is taken away through the discharge collector from the filter — press. The solid phase, kept by the filter cloth is pre-pressed and, if provided by technology, is washed. The washing liquid enters the chambers through a feeding collector. Washing filtrate is removed from the filter-press through the discharge collector.

After washing the sediment is again pressed by rubber diaphragms, dried by compressed air and is discharged when opening the filter press. Plates hang up on special eye bars. Cloth moving drive is switched on. The sediment is discharged on the cloth from interplate area and pours into charging-bins by the both sides of filter. The cloth is pulled through the regeneration chamber, washed and the filter — press is clamped again, and the operating cycle is repeated. Duration of process steps and their sequence are determined experimentally or by results of KMP type filter operation by using of similar suspension.

Filter-pressof KMP type have three designs depending on material of the parts contacting with the operating medium: made of carbon steel is for neutral and alkaline suspensions filtering; of corrosion resistant steel is for aggressive suspensions filtering; of titanium alloy VT 1–0 is for aggressive suspensions filtering. Filter-presses of KMP type are supplied with electrical equipment of industrial and explosion proof designs with class no less than V3T3 with control system based on electrical relays or pneumatic elements (for rooms categories BI-a and BII-a), as well as based on microprocessor equipment.

ENCE GmbH (ЭНЦЕ ГмбХ) Company underlines the following principal advantages of filter-presses of KMP type in comparison with their analogues:

  • Filter-press fast readjustment,
  • Filtration process time reducing,
  • Filtering high capacity,
  • Availability of conventional and microprocessor control and monitoring systems,
  • Perfect safety measures,
  • Efficient maintenance

These qualities make these filter-presses indispensables for many industries, including the coal, ore-dressing, metallurgical, chemical, machinery and energy industries.
