Chamber Filter Press
1. Product Overview
The JINGWO Chamber Filter Press is a widely used pressure filtration system for industrial solid-liquid separation. It uses recessed polypropylene filter plates to form sealed filter chambers, where slurry is pumped in under pressure and solids are retained by the filter cloth while filtrate is discharged through the plate channels.
This product is suitable for wastewater treatment, sludge dewatering, mining tailings, chemical processing, coal washing, papermaking, textile dyeing, food processing, pharmaceutical manufacturing and building material slurry treatment. It is a practical choice when the project requires stable operation, clear filtrate, good cake formation and a lower maintenance cost than many continuous dewatering systems.
Manual, semi-automatic and fully automatic configurations can be selected according to the treatment capacity, labor cost, site layout and budget. JINGWO can also provide the matching filter cloth, filter plates, feed pump, dosing equipment, conveyor and control cabinet as part of a complete filtration solution.
2. Working Principle
A chamber filter press works by closing a series of recessed plates, feeding slurry into the chamber cavities, forming a filter cake and then opening the plate pack for cake discharge. The process is intermittent but highly efficient for batch dewatering applications.
● Plate closing: the plate pack is compressed by manual or hydraulic pressure to create sealed filter chambers.
● Slurry feeding: slurry is pumped into the chambers through the feed port and distributed across each plate cavity.
● Pressure filtration: liquid passes through the filter cloth and plate drainage channels, while solids are retained on the cloth surface.
● Cake formation: solids gradually build up into a compact filter cake as filtration pressure and cycle time increase.
● Optional post-treatment: air blow, cake washing or automatic cloth washing can be configured when required by the process.
● Cake discharge: the press opens, plates are shifted manually or automatically, and filter cakes are discharged for disposal or reuse.
3. Main Structure and Features
Reinforced Anti-Corrosion Frame
The frame is welded from heavy-duty carbon steel for stable load-bearing performance. Surface sandblasting, rust removal and anti-corrosion coating help the equipment withstand humid, dusty and corrosive industrial environments. Stainless-steel cladding or special coatings can be evaluated for food, pharmaceutical or highly corrosive applications.
Polypropylene Recessed Chamber Plates
The recessed PP filter plate is designed to form a sealed filtration chamber with good chemical resistance, aging resistance and stable drainage performance. The chamber structure helps reduce slurry leakage and supports consistent filter cake formation.
Manual, Semi-Automatic and Fully Automatic Operation
Manual models suit small-capacity or intermittent operation. Semi-automatic models use hydraulic closing and opening with manual plate shifting. Fully automatic models can use PLC control, a touch screen, automatic pressure holding, automatic plate shifting and automatic cake discharge to reduce labor input.
Hydraulic Pressing System
Semi-automatic and automatic models use a hydraulic closing system to provide stable plate compression and pressure holding. Safety functions such as pressure control, overload protection and controlled release can be configured according to the project requirement.
Matched Industrial Filter Cloth
Filter cloth can be selected based on the material being filtered, filtration accuracy, cake release requirement and chemical conditions. Common cloth options include polypropylene, polyester, nylon, monofilament and non-woven cloth.
