There are currently two main types of belt vacuum filters in China, namely, the fixed vacuum box and the mobile vacuum box. Vacuum box fixed filter (also known as fixed chamber belt vacuum filter, rubber belt vacuum filter) is a ring-shaped belt that drags the filter cloth to slide on the vacuum box, which can achieve continuous vacuum and avoid the mobile filter of the vacuum box. The vacuum switching link of the machine, so from the feeding, filtering, washing, dewatering, unloading to the cleaning and regeneration of the filter cloth, the whole process realizes continuous operation, so its production capacity is high, the filtering speed is high, the washing effect is good, and the filter cake contains Low moisture content. At the same time, the belt speed, feed volume, slurry concentration, washing water volume, vacuum degree, washing zone and drying zone can all be selected ideal parameters according to production needs. This model has few wearing parts and low failure rate, can realize long-period continuous operation, stable operation, simple operation, low labor intensity and low operating cost.

Rubber belt vacuum filter, suitable for filtering coarse particles, high density, high concentration filter pulp, and filter cakes that need to be washed multiple times. It can be widely used in metallurgy, mining, chemical industry, electric power, food, coal, papermaking and Pharmaceutical, power plant flue gas desulfurization and other industrial sectors.
