Porcelain Industry Waste Water Belt Filter Press for Mining Industry Urban Sewage Treatment
Rubber vacuum belt filter press uses filter cloth as the media. It is a high-efficient separating equipment to separate the liquid from the solid by making full use of gravity and vacuum suction. It is widely applied in many fields, such as metallurgy, chemical industry, papermaking, food industry, pharmacy, coal washing, and environmental protection etc.
How does a vacuum filter press work?
Step1: Feed slurry is distributed continuously on the filter cloth.
Step2: Vacuum sucks the liquid into the vacuum box through the filter cloth, but the solid remains on the filter cloth.
Step3: The vacuum pulls air through the filter cake and continues to remove moisture from the filter cakeas the filter cloth moves forward.
Step4: The filter cake is washed by the washing device to get rid of impurities. Additional drying of the filter cakes follows the washing.
Step5: In the end, the filter cake is discharged from the filter cloth to a conveyor to the next process step.
Step6: The filtrate and air in the vacuum box flow through filtrate pipe and a gas-water separator. The filtrate thus is pumped to the next step in the process.
Vacuum belt filter press is widely applied in many fields, such as tailings,municipal sludge and industrial sludge, metallurgy, chemical industry, coal washing, and environmental protection etc.
1 Vacuum sealing: vacuum belt filter press is equipped a fixed vacuum box, the rubber belt moves on the vacuum box, the water can be functioned as the lubricant as well as coolant, thus creating a good vacuum condition.
2 Long service life of rubber belt: in respect of support, this machine equipped with rollers, thus reducing the friction and extending the belt's service life.
3 Easy to be installed and maintained: the machine adopts modularized structure which can be dismantled easily.
4 High efficiency: the machine achieves continuous filtration, materials are kept in vacuum condition in the whole procession.
Vacuum belt filter press use filter cloth as medium. It takes advantage of gravity and vacuum section to achieve solid-liquid separation. It adopts ring shaped rubber belt as vacuum vessel. The ring shaped belt moves under the power of motor, and the filter cloth which wrapped on the belt also moves along it. The slurry is distributed uniformly on the filter cloth by the distributing device. Vacuum section will be formed on the rubber belt when the vacuum system begins to work. And liquid pass through the filter cloth under the power of subatmospheric pressure and gravity; solid material are stopped and forms cakes on the cloth. The liquid will be collected by the row liquid separator and can be reused. Cake will be discharged when the filter cloth separates from the rubber belt.
