Silicon Carbide Ceramic Foam Filter

Q: The ultrasonic wave of ceramic filter is not good. What's going on?: The earliest filtration was mostly gravity filtration, which was followed by pressure filtration to increase the rate of filtration, followed by vacuum filtration. The drum vacuum filter invented in the early twentieth Century realized the continuous operation of the filter. Since then, various types of continuous filters have appeared. Intermittent operating filters (such as plate and frame press filters) are developed for automatic operation, and the filtration area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.

Q: Is the filter plate of the ceramic filter afraid of freezing?: The ceramic filter plate by table and the distribution of a large number of porous capillary ceramic filter, when working in the water slurry channel is used so the microporous ceramic filter plate internal residual has a lot of water, such as low temperature, the inside of the frozen water volume will swell, causing damage to the ceramic the inside of the microporous filter plate structure.

Q: What are the poor filtration effects of vacuum disc filters?: The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.On the other hand, as the spindle speed slows down, the thickness of the slurry is thickened, and the moisture of the concentrate is also affected. For viscous material, ceramic filter with ceramic plate to work as filter media, when the cake is formed gradually into the porous filter medium filter cake itself, and the cake is not easy to form a viscous material, forming a dry cake appearance does not slow, the spindle speed is easy to reduce the water content of concentrate. Similarly, the spindle speed is accelerated, the cake formation time in the vacuum zone is shortened, and the slurry thickness is reduced, and the material can be improved for the easy molding material. But the spindle speed is too fast to be cleaned after each cycle of the ceramic plate. As for the viscous material, the cake is difficult to form after the spindle speed increases, and it will affect the capacity. Therefore, the use of ceramic filter should focus on the inherent nature of the concentrate to explore the best spindle speed.

Q: What are the causes of the powder moisture in the ceramic filter?: Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.

Q: The efficiency of ceramic filter is low. What's wrong with it?: Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency.

Q: The vacuum degree of the ceramic filter is normal and the cake water is large: There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure

Q: Does the ceramic factory use hydrochloric acid?: Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.

Q: Ceramic filter cleaning, sulfuric acid cleaning: Ceramic filter medium is ceramic, ceramic generally resistant to strong acid, alkali, cleaning, it is best to use nitric acid, hydrochloric acid next, not recommended to use sulfuric acid.

Q: Ceramic filter suddenly do not smoke, a little later on their own good, what reason?: How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect

Q: What are the reasons for the program alarm of ceramic filter?: If you say "lean" is the ceramic filter suction when the ceramic filter plate into a cake of thin, high water content, is the ceramic filter for their own reasons, can from the following aspects: the investigation considering this phenomenon is always so recently or just happened, if you have been so, probably because your selection is not suitable for pulp the ceramic filter (such as mud content, fine grain size, ceramic filter plate selection such as inconsistent or unqualified ceramic filter). If this anomaly has occurred recently, it is possible to change the ore condition, and the operation parameters of ceramic filters or the cleaning are not up to standard. You can check the vacuum system (vacuum generally ranges from -0.09 to -0.075MPa), backwashing system (generally refers to the filtered water recoil 0.07 ~ 0.12MPa), acid (HNO3 system standards), ultrasonic system is normal.
