Recessed Chamber Filter Press

Professional Solid-Liquid Separation Equipment for Enhanced Industrial Production

Automatic washing filter press equipment

In the chemical, environmental, mining, food, and pharmaceutical industries, efficient solid-liquid separation is crucial for ensuring production efficiency, controlling costs, and achieving environmental goals. Loway chamber filter presses feature mature design, stable performance, flexible configuration, and exceptional separation capabilities.

Superior Separation Performance

High-strength filter plates combined with precision filter cloths create sealed filtration chambers under high pressure. Effectively captures fine solid particles, producing high-quality filter cake with moisture content typically 30%-60% (depending on material properties) and crystal-clear filtrate.

Powerful Processing Capacity

Modular design supports flexible expansion of filtration area, easily handling different scales of industrial solid-liquid separation requirements for both large-scale continuous production and batch processing.

Wide Material Adaptability

The core advantage lies in universality. Whether mining tailings dewatering, chemical catalyst filtration and recovery, municipal sewage treatment plant sludge deep dewatering, or fine material filtration in food and pharmaceutical industries, Loway chamber filter presses operate reliably.

Durable and Easy Maintenance

Main frame constructed with high-quality steel, key components like filter plates and hydraulic systems carefully manufactured to ensure long-term stable operation under harsh conditions. Simple daily maintenance operations like filter cloth replacement and plate cleaning effectively reduce equipment lifecycle costs.

High Economic Efficiency

Relatively simple structure with energy consumption mainly concentrated in hydraulic compression and plate pulling discharge processes. Compared to complex models, initial investment and maintenance costs are more advantageous, making it the preferred choice for users seeking cost-effective solid-liquid separation equipment.

Safe and Stable Operation

Equipped with reliable hydraulic locking and electrical protection devices (overpressure protection, travel limits, etc.), ensuring operator safety and smooth equipment operation.

Chamer Filter Press Definition

A chamber filter press is a mechanical equipment for solid-liquid separation by applying pressure. It mainly consists of filter plates, filter cloths, a frame, a hydraulic system, and a control system.

 

Its working principle is as follows: The filter plates are compressed to form sealed filter chambers, where the suspension is filtered. Filter cloths retain solid particles to form filter cakes, while the liquid passes through the cloths and is discharged, realizing solid-liquid separation.

 

This equipment is widely applied in sludge dewatering, sewage purification, material purification, etc. With a processing capacity ranging from 5 to 100 tons per hour, it caters to various needs—from small laboratory use to large-scale industrial production lines.

Technical Analysis of Chamber Filter Press

Filter Plates: Core for Separation Performance

Material Selection & Characteristics

  • Reinforced Polypropylene (PP) Filter Plates: Occupying over 70% market share, density only 1.1g/cm³, resistant to acid-alkali corrosion (pH 2-12), working temperature -20℃~80℃, suitable for sewage treatment, chemical slurry filtration, and other conventional scenarios. Test data shows that in municipal sludge treatment, these material filter plates operate continuously for 5 years with a damage rate below 5%, and maintenance costs are reduced by 60% compared to traditional cast iron filter plates.
  • Stainless Steel (304/316L) Filter Plates: Food-grade certified (FDA standards), high temperature resistant up to 150℃, chloride ion corrosion resistant (316L material suitable for Cl⁻>1000ppm environments), mainly used in food, pharmaceutical, electronic materials, and other clean fields. For example, in syrup filtration, 304 stainless steel filter plates can achievea  processing capacity of 50 tons/hour, filter cake sugar content ≤2%, fully complying with GB 13104 food sugar hygiene standards.
  • Composite Material Filter Plates: Using rubber-covered stainless steel technology, combining elastic compression performance with wear resistance characteristics. In mining tailings and high-viscosity material processing, filter cake moisture content can be reduced by 10%-15%, equipment life extended to over 8 years, suitable for harsh working conditions.

Structural Design Optimization

Frameless integrated design with trapezoidal groove structure on sealing surfaces improves sealing by 30% compared to traditional filter frame types, controlling leakage rate below 0.05%. Filter plate surface flow guide ribs increase filtrate flow rate by 20%, shortening single cycle filtration time by 15%.

Intelligent Hydraulic System

Servo motor driven with pressure control accuracy of ±0.1MPa, 30% more energy efficient than traditional oil pumps, noise ≤75dB. Standard automatic pressure maintenance function, pressure range 0.6-1.2MPa (standard models), automatically adjustable according to material characteristics. For example, in sand washing wastewater treatment, the system dynamically adjusts pressure based on solid content, ensuring clean water reuse rate stable above 90%.

PLC Control System

Supports remote monitoring, fault diagnosis (response time ≤10 seconds), and parameter adaptive adjustment. Built-in algorithms optimize filtration cycles based on material concentration and temperature.
Data visualization interface displays 12 core parameters, including pressure, flow rate, and filter cake thickness in real-time, supports historical data export (CSV format) for production management and process optimization.

Four-Stage Working Process of Chamber Filter Press

Feeding Stage (0-15 minutes)

Suspension liquid is injected into filter chambers through centrifugal/screw pumps with feeding pressure 0.3-0.6MPa. Intelligent system automatically adjusts feeding flow rate based on material solid content (laboratory pre-processing data). For example, when processing municipal sludge with 15% solid content, feeding speed is controlled at 8m³/h, ensuring uniform initial filter cake layer formation with filtrate turbidity ≤50NTU.

Filtration Stage (20-60 minutes)

Solid particles gradually accumulate on filter cloth surface forming filter cake, filtrate passes through filter cloth micropores (pore size 5-10μm) and is discharged, filter chamber pressure gradually rises to working pressure. Filter cloth uses monofilament/multifilament blended technology with fine particle retention rate ≥99.5%. In lithium battery cathode material filtration, 5μm and below particle removal rate reaches 99.8%, ensuring filtrate precision.

Pressing Stage (Optional, 10-30 minutes)

Secondary compression of filter cake through mechanical pressure further reduces moisture content. Test data shows that in mining tailings processing, after pressing, filter cake moisture content can be reduced from 35% to 25%, volume reduced by 40%, significantly lowering transportation costs and subsequent processing load.

Discharge Stage (5-20 minutes)

Hydraulic system automatically loosens filter plates, using cloth washing discharge (filter plate opening angle ≥120°, cake drop rate 95%) or mechanical vibration technology for unloading. Supporting filter cloth cleaning device (water pressure ≥0.8MPa) automatically washes filter cloths, single cycle time shortened by 20% compared to traditional models.

Common Questions

Have More Questions? Our technical team is ready to provide detailed, personalized guidance.

Q1:  How to choose filter cloth material?
Match to material properties:

 

  • Acid-resistant (≤130℃): Polyester; alkali-resistant (≤90℃): Polypropylene.
  • High-precision (<5μm): Monofilament (uniform pores); high-viscosity: Multifilament (anti-clogging).
  • Food/pharmaceutical: FDA-certified cloth.

Possible causes:

  1. Feeding pressure below rated (need 0.6-1.2MPa).
  2. Cloth clogging (weekly chemical cleaning recommended).
  3. Fine particles (add 0.1%-0.3% flocculant).
  4. Inadequate extrusion pressure (check hydraulic seals).

Yes, advanced automated presses include adaptive control systems that detect changes in slurry characteristics and adjust operating parameters accordingly, maintaining optimal performance despite feed variations.
