Belt Filter Press for Coal Slurry Drying (DY3000)

Belt filter press for coal slurry drying
The belt filter press is an industrial machine, used for solid/liquid separation processes, particularly thedewatering of sludges in the chemical industry, mining and water treatment. The process offiltration is primarily obtained by passing a pair of filtering cloths and belts through a system of rollers.
Application: Belt filter press
Our belt filter press widely used for sludge (effluent) thickening and dewatering in the following field:
1. Paper & pulp sewage;
2. Printing/dyeing (textile) sewage;
3. Municipal sewage
4. Stone & mining sewage;
5. Food & beverage sewage;
6. Livestock sewage;
7. Slaught house sewage;
8. Brewery processing wastewater.
9. Leather & tannery sewage;

How it works: Belt filter press
The feed sludge to be dewatered is introduced from a hopper between two filter cloths (supported by perforated belts) which pass through a convoluted arrangement of rollers. As the belts are fed through the rollers, water is squeezed out of the sludge. When the belts pass through the final pair of rollers in the process, the filter cloths are separated and the filter cake is scraped off into a suitable container. [1] A belt filter is generally used in phosphatic fertiliser plants to separate the solid from slurry. It comprises washing to different zone to minimise the product losses. Belt filters use a vacuum system to minimise offgas and effluent during operations. It has applications in many other areas of industry.

Most Belt Filter Press operations can be divided into three general stages - initial de-watering, which makes the sludge pulp; Pressing or medium pressure filtration, which conditions the sludge for high pressure filtration quality; And high pressure filtration, which raises the dry solids content in the sludge cake to the optimum.
Pressure is first applied in a low pressure wedge zone (#4), which begins squeezing remaining water out of the sludge. Further de-watering occurs in the medium pressure zone (#5). Where two large perforated drums of decreasing size apply the pressure. Rollers perform the final de-watering in the high pressure zone (#6). The sludge cake (filtered solids) then exits the machine at (#7). (#8) indicates the locations of the belt cleaning spray stations. The belting on a belt filter press must be continuously washed with clear water to keep it from blinding, and this is accomplished by water spray bars placed above returning belt.
