CATHAY belt filter press Continuous pressing and dehydration High sludge volume reduction efficiency

CATHAY belt filter press: continuous pressing, ideal choice for efficient dehydration

1. Three-stage pressing to achieve deep dehydration

CATHAY belt filter press adopts advanced three-stage pressing technology, perfectly combining gravity dehydration, wedge pressing and high-pressure roller pressing to build an efficient dehydration system. When the sludge or slurry is evenly distributed on the filter belt through the feeding device, it first enters the gravity dehydration area. Under the action of gravity, a large amount of free water is quickly discharged through the filter belt, so that the material is initially dehydrated and the moisture content is reduced to 85%-90%. Subsequently, the material enters the wedge pressing area with the filter belt. The two filter belts gradually approach to form a wedge-shaped space, pre-pressing the material and further squeezing out some water to prepare for subsequent high-pressure pressing. At this time, the moisture content can be reduced to 75%-80%. Finally, the material enters the high-pressure roller pressing area. Under the strong squeezing of multiple groups of pressing rollers, the interstitial water in the material is completely squeezed out, and the moisture content is greatly reduced to 60%-70%, forming a filter cake with low moisture content and tight structure, completing the deep dehydration process.

2. Widely adaptable to meet various dehydration needs

Whether it is domestic sludge generated by municipal sewage treatment, or printing and dyeing sludge, papermaking sludge, chemical sludge, food processing sludge, etc. discharged in industrial production, CATHAY belt filter press can efficiently handle them. In the mining industry, the tailings sludge generated in the mineral processing process can be dehydrated to reduce its moisture content to an appropriate level, which is convenient for dry stacking or reuse of tailings, reducing the area occupied by tailings ponds and environmental pollution risks; in the metallurgical industry, the dehydration treatment of smelting sludge can effectively reduce the moisture content of sludge and create conditions for the resource utilization of sludge. In addition, in the dehydration treatment of organic waste in agriculture, environmental protection and other fields, the equipment can also perform excellently and has strong adaptability.

3. Excellent performance, ensuring efficient and stable operation

High dehydration efficiency: With wide filter belt design, the processing capacity of a single device can reach 10-50 tons per hour, and it can run continuously without interruption. The dehydration efficiency is 40%-60% higher than that of traditional filter press equipment, which can quickly respond to large-scale dehydration needs and ensure production rhythm.

Low filter cake moisture content: Through the layer-by-layer effect of the three-stage pressing process, the filter cake moisture content is significantly lower than that of similar equipment. Taking municipal sludge as an example, the moisture content after treatment can be stabilized at 60%-65%, which greatly reduces the volume of sludge, reduces the subsequent transportation and disposal costs, and reduces potential pollution to the environment.

Strong filter belt durability: The filter belt is made of high-strength, wear-resistant and corrosion-resistant polyester material. The surface is specially treated with excellent dehydration and wear resistance. The service life can reach 3000-5000 hours, reducing the frequency and cost of filter belt replacement.

4. Intelligent control to improve the convenience of production management

CATHAY belt filter press is equipped with an advanced PLC intelligent control system, which monitors the equipment operation status in real time through high-precision sensors, such as filter belt tension, pressing pressure, feed volume, filter cake thickness and other parameters. The operator only needs to set the relevant parameters on the touch screen in the central control room, and the system can automatically adjust the filter belt speed, pressing roller pressure, etc. to achieve full automatic operation of the equipment. At the same time, the system has the function of automatic fault diagnosis and alarm. When the equipment has faults such as filter belt deviation and abnormal tension, it can promptly issue an alarm and display the fault location and treatment suggestions, which is convenient for rapid troubleshooting and maintenance, reducing manual intervention, reducing labor intensity, and improving production management efficiency.

5. Structural optimization to ensure the durability of the equipment

The equipment frame is welded with high-strength steel. After anti-corrosion treatment, it has excellent corrosion resistance and deformation resistance. It can adapt to humid and dusty working environments and has a service life of more than 10 years. The pressing roller is made of high-quality alloy material, and the surface is specially hardened. It has high hardness and strong wear resistance, ensuring long-term and stable pressing effect. The filter belt deviation correction device adopts pneumatic control, which is sensitive and can correct the filter belt deviation phenomenon in time, avoid filter belt wear and equipment failure, and ensure the continuous and stable operation of the equipment.

6. Energy saving and consumption reduction, practice the concept of green development

In the design process, CATHAY pays attention to energy saving and consumption reduction. The drive motor adopts an efficient and energy-saving model, and the energy consumption is reduced by 15%-20% compared with traditional equipment; at the same time, the layout and pressure distribution of the pressing roller are reasonably optimized to reduce energy loss while ensuring the dehydration effect. During the operation of the equipment, there is no need to add a large amount of flocculant, which not only reduces the cost of the agent, but also reduces the secondary pollution to the environment, which is in line with the development trend of green environmental protection.
