Disk vacuum filter is a kind of common solid-liquid separation equipment, the filter disk is composed of a speed regulating motor through a speed reducer and gear transmission to drive, so that the fill slurry tank at certain speed continuous rotation. When the filter disk of a filter fan in the filtration and adsorption area, with the help of the vacuum pump in the filter medium formed on both sides of the pressure difference, the solid material is adsorbed on the filter medium ( cloth ) and form a filter cake and the filtrate after filtrate pipe and discharge distribution head. When a filter fan from the pulp liquid level from and into the dewatering zone, filter cake in a vacuum suction force under the action of water, continuously and filter cake separation, further from the filtrate pipe and a dispensing head discharge, thus drying filter cake. Enter the discharge area, the filter cake in a reverse blowing and blade under the action of the filter disk, from unload and into the discharge chute, set by the mine belt conveyer transports, the entire operation process of continuously
Its main technical characteristics are as follows
In 1, combined with the existing filter fan using some defects, we design a new type of filter fan, the dehydration holes are uniformly distributed, hole rate reasonably, strength ( filter fan material for high strength engineering plastics ), long service life, life of average increased by 1---1.5 times, and long service life of the filter cloth. At the same time filter fan of large effective area, improving the handling capacity of the filter.
In 2, the filtrate pipe structure optimized design, to eliminate the primary flange rubber aging due to the leakage phenomenon.
In 3, a mixing shaft end of the domestic initiative", a permanent magnet, rubber water seal" three combinations of flexible sealing mode, effectively prevent slurry leakage.
4, made of special wear-resistant boron cast iron friction, good sealing effect cliffide flower.
5, filtrate pipe for high strength wear resistant ceramic composite steel pipe, prolonging 5 times above.
6, with 10small arc-shaped pressing block continuous interlocking will filter fan press is positioned in a plane. Make the maintenance personnel to replace the filter fan or cloth when workload reduction, labor intensity is greatly reduced.
7, driving stepless speed change, depending on material concentration and flow regulation ( AC adjustable speed motor or frequency converter ) in order to achieve the desired effect of the work.
8, dry pumps centralized multipoint automatic lubrication, guarantee the normal operation of equipment.
The machine is to iron ore, nonferrous metal ore concentrate dewatering and specially designed model of disc vacuum filter, also suitable for coal washing processing, non-metallic minerals, chemical, environmental protection work of.
