Belt filter press

The belt filter press is a widely used solid-liquid separation device, playing a crucial role in various industries.

Structure: It mainly consists of a series of components. The filter belts are the core part, usually made of high-quality synthetic materials with excellent filtration performance and durability. There are also pressing rollers, which apply pressure to the filter belts to squeeze out the liquid in the sludge. Additionally, it includes a feeding device to evenly distribute the sludge onto the filter belts, and a washing device to clean the filter belts and maintain their filtration efficiency.

Working Principle: The sludge is first fed onto the filter belt through the feeding device. As the belt moves forward, the free water in the sludge is gradually drained by gravity. Then, the sludge enters the pressing area where the pressing rollers apply pressure, further squeezing out the remaining liquid. Finally, the dewatered sludge is discharged from the end of the filter belt, while the filtrate is collected separately.

Applications: In the municipal sewage treatment industry, it is used to dewater the excess sludge generated in the treatment process. In the mining industry, it can handle the tailings slurry to separate valuable minerals and water. In the food and beverage industry, it is applied to deal with the wastewater containing solid residues, achieving the recycling of resources and the reduction of pollution.

Advantages: It has a high treatment capacity, capable of processing a large amount of sludge in a short time. The continuous operation mode improves work efficiency. Also, it can achieve relatively high dewatering efficiency, reducing the moisture content of the sludge effectively. And it is relatively easy to operate and maintain, with a simple structure that is convenient for daily inspection and repair.
