Disc Vacuum Filter
Widely used in mining, coal, metallurgy, chemical industry, sewage treatment and other non-ferrous metal and non-metal industries.
Capacity:5-1120 t/h
Applicable materials: It is suitable for solid-liquid separation of mineral processing and tailings. The fineness ranges from -200 mesh to -450 mesh and various ultra-fine materials.
Description
The disc vacuum filter is a solid-liquid separation equipment that uses vacuum as the filtration power to separate the slurry from solid-liquid. This machine adopts advanced technologies such as filter disc guide, variable-speed mixing, reverse-blowing air discharge, automatic centralized lubrication, etc. It is a dehydration equipment with excellent performance and reliable use. This machine is a new disc vacuum filter specially designed to dehydrate iron ore and non-ferrous metal concentrates. It is also suitable for coal washing, mineral processing, non-metallic ores, and chemical industry.
A vacuum disc filter can provide highly precise filtration in the smallest pads. Several discs are in-line are connected to a center that turns through the slurry and the evacuation zone. Each circle is comprised of sectors, molded like a cut of pizza. Each sector is furrowed or made of a punch plate to permit fluid to pass through a cloth sack, into the division, and out the center barrel. Each disc filters the slurry at the same time on both sides. Vacuum disc filters are ideal for these cases in which the slurry has highly liquid substances and the cake is easily dischargeable.
Advantages
- The machine adopts program control, which is easy to operate and runs smoothly, reducing personnel operation.
- Increase the use time by more than ten times. The filtrate pipe is made of high-strength ceramic material and steel pipe. The main drive is continuously variable speed.
- The friction plate is made of unique wear-resistant materials, which combines rigidity and softness with a good sealing effect and long service life.
- Significant energy-saving effect, low operating cost, and low consumption of spare parts.
Principle
Slime absorbing zone: The filter plate immersed in the slime while in operation produces a surface absorption of filter cake, with the action of capillarity and integrated with vacuum pressure. Filtrate enters the distributing valve and drainage tank through the filter plate.
Leaching zone: Filter cake coming out from slime hopper receives spray washing.
Drying zone: Continuous dehydration for filter cake is conducted with high vacuum force.
Discharging Zone: Scraper will automaticly discharge materials once entering the vacuum-free condition.
Back flushing: Service water or filtrate enters the ceramic plate through distributing valve and cleaning the blocked minihole entoectad. Cleaning with ultrasonic and low-density acid after the ceramic plate is used for one period is necessary to maintain the efficient service life of the ceramic plate.
