Magnesium Dewatering Vacuum Ceramic Filter Solid Liquid Separation

Summary

A vacuum ceramic filter is designed to separate liquids from solids for dewatering purposes. The device consists of a rotator, slurry tank, ceramic filter plate, distributor, discharge scraper, cleaning device, frame, agitating device, pipe system, vacuum system, automatic acid dosing system, automatic lubricating system, valve and discharge chute. The operation and construction principle of vacuum ceramic filter resemble those of a conventional disc filter, but the filter medium is replaced by a finely porous ceramic disc. The disc material is inert, has a long operational life and is resistant to almost all chemicals. Performance can be optimized by taking into account all those factors which affect the overall efficiency of the separation process. Some of the variables affecting the performance of a vacuum ceramic filter include the solid concentration, speed rotation of the disc, slurry level in the feed basin, temperature of the feed slurry, and the pressure during dewatering stages and filter cake formation.

Working principle

The process is used during a large continuous process of separating free filtering suspensions where washing is not required.[2] Basically the filter works to separates solid-liquid mixtures by removing the water from mineral concentrates and moulding the feed slurries into pellets.[3] This is accomplished by capillary action under low vacuum pressure.[2] The pelletizing of the slurries is done by adding some solid matter to the sewage sludge so that water can be easily removed from the mixture. Eventually, the final cake products contain very little moisture and can be deposited as sewage. This process is commonly followed by bleaching and heating the cake. The end product of this filtration is a dry cake and filtrate containing no solid product.

Features

1. High vacuum(pressure 0.09~0.098Mpa), low moisture of filter cake. Solid content of filtrate<50ppm. Can be repeatedly used, reducing emissions.

2. Compared with traditional filtering euqipment energy savig about 90%above, lowenergy consumption, low operation cost.

3. Added compared with traditional ceramic filtering device filter cake washing, suitable for washing materials.

4. A high degree of automation, reducing labor intensity.

5. Compact structure, small occupation area, convenient installation and maintenance.

 6. Advanced drainage system, suitable for any use of working conditions.
