Ceramic Foam Filter has the advantages of high porosity, good thermal shock resistance,high mechanical strength, large specific surface and stable chemical property. In addition, with the excellent function of filtering, residuum collection and absorption, it can remove the impurities of 1-10μm efficiently. The outstanding three dimensional structure can reduce the turbulence and extrude the air in mould filling, provide consistent and rapid metal flow, improve the casting quality prominently.Ceramic Foam Filter can also be applied in gas treatment at high temperature, carrier of catalyzer, solid thermal exchange and special filling for chemical industry.
With more than ten years of research and development, enriches its product scope with different series of foam filters such as Alumina, Silicon Carbide and Zirconia.
Alumina foam filter (JG-1): For molten metal filtering under the temperature of 1200℃;
Silicon Carbide foam filter (JG-201, JG-202): For molten metal filtering under the temperature of 1550℃
Zirconia foam filter (JG-3): For molten metal filtering under temperature of 1700℃.
APPLICATION OF CERAMIC FOAM FILTER
Selection of ceramic foam filter
1) Selection of pore size is based on the weight and material of casting, regularly 10ppi for Stainless Steel; 10ppi for Ductile Iron; 20ppi for Grey Iron; 15ppi, 20ppi and 30ppi for non-ferrous alloy castings:
2) Foam filter size is decided by the sculpt, fusion and the characteristic of the ceramic foam filters.
3)'Ceramic foam filters should be fixed in the runner and ensure its uniform pressure.
4) Strictly control the pouring pressure and reduce the impact of hot molten metal.
5) Ceramic foam filters under ultra-high temperature are prohibited.
6) Strictly avoid using the ceramic foam filters to control the flow speed of molten metals
Attentions for store and application
Ceramic foam filters should be stored in dry environment to avoid moisture. Ceramic foam filters are fragile materials, rough handling in transportation is prohibited. It is recommended to blow the scum with compressed air before using
The advantage of application ofceramic foam filter
1) Reduce the defective rate and improve the casting yield.
2) Reduce the machining allowances and improve machinability of casting.
3) Improve the mechanical property of casting
4) Simplify pouring systems and improve the utilization ratio of mould
TYPICAL INSTALLATION OF CERAMIC FOAM FILTERS
Based on the characteristic of casting and the filters' working condition, ceramic foam filters can be fixed in different parts of the pouring system
1、Installation in the pouring cup: Commonly for precision casting and the casting of iron model covers the granulated substance
2、Horizontal installation in vertical runner: For small part with few pouring molten iron, especially for casting system with a vertical runner located at mould center and multiple branches of horizontal runner
3、Horizontally installation in horizontal runner: It makes molten metal casting stable, avoiding directly impacting the filter. This will increase slag blocking ability and make installation convenient.
4、Vertically installation in horizontal runner: To increase molten metal flow speed and enhance the filling capacity. Since molten metal directly impacts the fillers, the impact resistance of filters should be considered
- Q: What are the poor filtration effects of vacuum disc filters?
- With the increase of the material level of the ceramic filter trough, the suction time of the ceramic filter plate in the vacuum zone increases, the thickness of the slurry increases and the productivity increases. But the drying time is relatively short, the water content of the concentrate will be increased. Select the best material level to ensure the production capacity and concentrate moisture requirements.
- 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: What happens when the pressure on the filter plate is uneven during backwashing?
- Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.
- Q: Why does not the iron filter of the ceramic filter work?
- The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
- Q: The working principle of ceramic filter
- The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.
- Q: Ceramic filter fineness thin mud suction is not what to do more
- Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.
- 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: 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?
- The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
- Q: How should the static and dynamic sealing points of the ceramic filter be leaking?
- The filtrate pump works to drain or recycle the water that has been pumped out. 6 、 cleaning system work, cleaning system includes backwashing (water pump pressure or height difference pressure), acid liquid (metering pump, automatic acid injection), ultrasonic (ultrasonic work), etc.. 7 、 control system and other electrical systems. In addition, the filter cake which is absorbed and dried on the ceramic filter plate is unloaded automatically by the scraper and then falls on the belt conveyor, and is conveyed to the concentrate storage yard by a belt conveyor.
