Introduction of Disk Vacuum Filter
Disk Vacuum Filter mainly used for solid-liquid separation with the vaccum as the filtering power. It can be used as the ideal filter for iron concentrate, copper concentrate, sulphur concentrate, Ti concentrate and other non Ferrous Metal concentrate and nonmetal concentrate dewatering and tailing Dewatering.
The split center barrel design with offset flow tubes allows Zhengzhou Hengxing vacuum disc filter systems to increase filtrate removal, reduce wear on each flow tube, and provide a stronger, more efficient snap blow.
Features of Disk Vacuum Filter
1. Highest specific throughput while maintaining a small footprint.
2. Small area taken easy to manufacture and strong adsorption ability, full dehydration.
3. Marked technical and economic effect.
4. Automated operation, high flexibility.
5. Simple maintenance, quick mounting of filter cells and two-part control discs for minimized maintenance effort.
Advantages of Disk Vacuum Filter
1. The capacity of the vacuum filter depends on the filtration speed.
2. If the solids in the suspended liquid are of large and even size, the clearance of filter residue will be less unblocked, and then the filtrate passes faster. Flocculating agent helps gather the fine particles to form lumps, which also increases the filtration speed.
3. For liquid in which solids sediment quickly, the vacuum filter in which add materials from above the filter medium is used to allow the large particles sediment first so as to avoid the block of filter medium and filter residue.
4. If the liquid is hard to filtrate, mix the liquid with large particles such as diatomite or bloating perlite to loose the filter residue; if the liquid is very sticky, heating the liquid helps reduce the stickiness; such doings help increase the filtration speed.
Working principle of Disk Vacuum Filter
The suspension is fed continuously into the trough and flows in the same direction as the rotating filter discs. Each filter disc is divided into filter segments. They rotate at 30-360rph, and approximately 40-52% of the surface area submerges into the suspension. The feed level in the trough is kept constant by weir plate or level regulation.
A vacuum is produced in the segment-shaped filter cells, which are covered with a filter bag. The liquid filters through the filter cloth, while the solid matter forms a filter cake of uniform thickness on the filter cloth and emerges with the disc from the trough.
As the disc filter rotates, the cake is demoistured by removing the liquid and discharged from the cloth at the end of this zone by means of compressed air (blow-back). The cake is discharged into the chute and further processed.
