High-Capacity Industrial Dewatering Belt Filter System

Toncin belt filter press is a high-efficiency solid-liquid separation device based on the principles of chemical flocculation contact filtration and mechanical extrusion. It features a simple process flow, high automation, continuous operation, convenient control, and adjustable working parameters. When used in conjunction with a gravity thickener, it can eliminate the need for a material concentration tank, thereby saving construction costs to some extent. As a result, it is gaining increasingly widespread application across various industries.

Currently, the belt filter press is widely used for sludge dewatering in municipal sewage, textile printing and dyeing, electroplating, papermaking, leather, brewing, food processing, coal washing, petrochemicals, chemical industry, metallurgy, pharmaceuticals, ceramics, and other sectors. It is also suitable for solid-liquid separation or leaching processes in industrial production.

Operating Principle:

1. Pre-treatment Stage
The flocculated material is evenly distributed on the filter belt. Under gravity, free water outside the flocs separates, reducing the moisture content of the sludge flocs and weakening their fluidity. The dewatering efficiency at this stage depends on the properties of the filter belt, the characteristics of the material, and the flocculation effect of the sludge. Gravity dewatering removes a significant portion of the water from the sludge.

2. Wedge Pre-pressing Dewatering Stage
After gravity dewatering, the material still retains relatively high fluidity, which does not meet the requirements for the pressing stage. Therefore, a wedge pre-pressing section is incorporated between the gravity dewatering and pressing stages. Through slight extrusion, surface free water is further removed, significantly reducing fluidity and preventing the material from being squeezed out during subsequent pressing. This creates stable conditions for effective pressing dewatering.

3. Pressing Dewatering Stage
After passing through the wedge pre-pressing stage, the material enters the pressing dewatering zone, which consists of a series of rollers arranged in descending order of diameter. As the roller diameter gradually decreases, the pressure on the material progressively increases. Simultaneously, shear forces are applied as the material passes over the rollers, removing most of the saturated water and completing the final dewatering process.

Why Choose Our Belt Filter Press?

The DYZ filter press is suitable for sludge dewatering systems in large water treatment projects and for material dewatering in various industrial and mining plants under harsh conditions.

1. It features an extended gravity drainage zone, followed by wedge and press sections. Operating pressure can reach 12 bar, ensuring high dewatering web performance.

2. The press incorporates high-strength, heavy-duty bearings and reinforced roller combinations, which simplify operation and maintenance.

3. The upper and lower filter webs are separately driven by frequency converters, achieving optimal load distribution.

4. Rollers are coated with high-quality polyethylene or rubber. Water rings installed at the roller ends effectively prevent water ingress and bearing damage.

5. Filter web regeneration is accomplished via stainless steel spray pipes and built-in brushes, greatly enhancing cleaning efficiency.

Our equipment is not just an efficient dewatering machine; it is a solution dedicated to helping you "reduce costs, improve efficiency, and achieve stable, worry-free operation."
