Rubber belt vacuum filter is a circular rubber band as a transmission belt vacuum filter. Rubber belt vacuum filter, filter media is the main cloth, when the rubber belt vacuum filter operation, the cloth was deposited in the annular rubber shop, in the motor driven joint exercise between the completion of the filtration and removal solution. 1, the rubber belt vacuum filter works rubber belt vacuum filter belt loop continuous operation by the motor drive, tape and vacuum slide between the contacts formed by ring friction with the water seal to prevent vacuum damage to the environment. Rubber belt vacuum filter, filter media is the main cloth, slurry uniform cloth from the fabric device on the cloth. Rubber belt vacuum filter vacuum chamber connected to a vacuum system, circular rubber belt to form a vacuum filtration area, in a vacuum, and gravity-driven, the filtrate through the filter cloth by the rubber band into the vacuum chamber, while the solid particles are retained cloth the formation of filter cake. Rubber belt vacuum filter cake ring rubber band will lead to movement through washing area and wash dry areas, and finally the cake removable. 2, rubber belt vacuum filter, the performance characteristics of rubber belt rubber belt vacuum filter process in motion, using the slurry of water, and water seal between the vacuum chamber. Meanwhile, the rubber belt vacuum filter using sealed water lubrication and cooling functions as a lubricant and coolant, reduce ring wear rubber and related components. Rubber belt vacuum filter is simple, and can run continuously. Rubber belt vacuum filter, filtration efficiency is better with a vacuum filter in series in the maximum handling capacity, the highest capacity, and the rubber belt vacuum filter, washing effect, access to better quality of the cake.
