Product Description:

Ceramic Foam Filter


Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses . With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. 

Size available:

7", 9", 12", 15", 17", 20", and 23", with porosities from PPI 10 to PPI 60(PPI ie pores per inch).

Other special sizes could be produced on request.


Product Applications:

Zirconia ceramic foam filters apply to purge and filter solution of carbon steel, steel alloy and stainless steel.

Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?
In unit time, the more turns of the drum, the greater the centrifugal force, the greater the rate of filtration in unit time, that is to say, the amount of filtrate in unit time is moreRotating drum vacuum filter, the greater the speed, the greater the filtration rate, but the shorter the time each turn, the amount of each filtrate will be reduced
Q:The vacuum degree of the ceramic filter is normal and the cake water is large?
The vacuum degree of the ceramic filter is normal at about -0.08MPa. Under normal circumstances, the water content of the filter cake treated with a ceramic filter is about 10%, and the moisture content of the tail filter cake is about 15%. The water content of the filter cake increases with the increase of water content in the ceramic filter.
Q:Is the filter plate of the ceramic filter afraid of freezing?
In addition, the temperature is one of the factors affecting the filter suction effect of ceramic filter. The lower the temperature, the worse the suction effect.Therefore, the ceramic filter plate, especially the ceramic filter plate after use, should be protected under low temperature environment.
Q:How can I avoid the backwash pressure in the production of ceramic filter?
Recoil of the ceramic filter is on the clean water under certain pressure, from the inside out flushing blockage blockage in the ceramic filter plate on the internal pore water pressure, the recoil is generally less than 0.12MPa, the pressure is too small or no recoil recoil effect is not good.
Q:How many degrees does the ceramic filter melt?
You should say clearly what ceramic you useHowever, as a melting furnace or filter medium, alumina products are the most versatile, but also silicon carbide, corundum, mullite, spinel and so on. They use very high temperatures.
Q:The efficiency of ceramic filter is low. What's wrong with it?
CleanThe cleaning of ceramic filter is divided into two parts: reverse flush cleaning (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board.Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure.Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.).
Q:What happens when the pressure on the filter plate is uneven during backwashing?
The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like device, through the pump) scraper discharge, discharge will complete a ceramic filter in the absorption cycle, slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles will cause blockage of filter media lose permeability so that the filtering effect of variation, in order to reduce the possibility of blockage, ceramic filter will enter the backwash (this process is like a water jet device). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
Q:Working principle, ultrasonic trouble and troubleshooting of ceramic filter
It is based on the action principle of capillary pore and realizes the solid-liquid separation through the capillary action principle of the micropore. Specifically, is the use of microporous ceramic plate water impermeable properties, extraction of ceramic plate and external cavity vacuum pressure, the suspended material groove under the action of the negative pressure adsorption on the ceramic plate, solid material through the porous ceramic plate can not be trapped in a ceramic plate surface, and the liquid due to the hydrophilic effect of vacuum pressure difference and ceramic plate by entering the gas-liquid distribution device, and then discharged or recycled, so as to achieve the purpose of solid-liquid separation.
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.
Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the 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 is poor, I hope to help you:
