1.Production of ceramic foam filter
Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
2. Functions of ceramic foam filter
1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;
2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;
3). Low head loss,easy operation,energy-saving;
4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;
5). Various sizes,shapes,apertures are available for kinds of foundry technique.

- 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: Why should filter core be used in backwash of ceramic filter?
- The filter in the water filter of ceramic filter is used for filtering water.
- 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?
- The faster the speed is, the shorter the time required for each turn, i.e., the shorter the filtration time, the less the filtrate will be
- 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. I analyze the reasons from two aspects.
- Q: Microporous ceramic filter plate cleaning
- Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
- Q: What is the reason that the ceramic filter does not absorb mineral powder?
- There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.
- Q: The vacuum degree of the ceramic filter is normal and the cake water is large?
- The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
- 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 is the reason that the whole ceramic filter does not attract ore?
- After the joint cleaning, 0~2 hours of suction effect may be good, 2~4 may drop slightly, 4 hours later will become worse and worse, or even suck. This case should first check the backwash water pressure (instantaneous maximum pressure should not be less than 0.08MPa) is to meet the requirements, should also advance down (to ensure normal and ultrasonic cleaning combined with nitric acid dosage sufficient) and prolong the cleaning time.
- Q: Can the ceramic plate filter the hot air?
- The cleaning of the ceramic filter is divided into two parts: reverse flushing (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.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment. We specialize in ceramic filter boards for many years and welcome exchanges.
