Vacuum Disc Filter

Vacuum Disc Filter, Vacuum Disk Filter, ceramic disc vacuum filter, Vacuum Ceramic Disc Filter for Mining Slurry Separation, Ceramic Rotary Vacuum Disc Filter for calcium salt dewatering, metal filter disc rotary vacuum filter

The ZPG series vacuum disc filter is designed for solid-liquid separation. The motor speed may be calibrated via gear and reducer adjustments, which in turn rotates the filtration disks at an even and manageable speed through the mineral slurry tank. To suit client’ varied demands, we can supply vacuum disc filters with varied filter diameter options.

Brief Introduction
The ceramic disc filter is a kind of equipment which use the vacuum negative pressure and the capillarity of ceramic plate to realize solid-liquid separation.

Extract air inside of the ceramic plate to make the pressure difference with external, under the negative pressure, the solids in the slurry tank will be absorbed on the ceramic plate surface. And the filtrate will be flow from the outside to inside of ceramic plate with negative pressure difference and the hydrophilicity of ceramic plate, so that to reach the purpose of the solid-liquid separation. vacuum permanent magnetic filter

Operation Principle

The ceramic plate immersed in the slurry tank, and the material cake layer formed on its surface under vacuum negative pressure and adsorbed by the plate capillary. The liquid passes through the inside of the plate and pipes to the vacuum tank and discharge out.

The cake on the plates running by main roller to drying area, and continues to dehydrate under vacuum function. Then running to cake discharging area (without vacuum) to discharge the cake by ceramic scraper.
After discharging, the ceramic plate running to the back washing area, the process water or compressed air will be enters to the ceramic plate inside by the back washing pipes, and washing the ceramic plate holes from inside to outside.

After working for one shift, the ceramic plate should be washed by ultrasonic waves and combined with low concentration acid to ensure its efficiency.

Main Features
Low power consumption, low operation cost (low vacuum loss), low cake moisture, low solids content in filtrate and can be reused. High automation, compact structure, small space occupied, and easy installation and maintenance.
