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 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: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's the reason for high water content in filtration copper concentrate?
- Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.
- Q:What about the leakage of the ceramic filter static and dynamic sealing points?
- When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.
- Q:The vacuum of ceramic filter is not enough
- Maybe the vacuum meter is broken. It doesn't show or show the data is different from the actual data.It could be the source of the vacuum, the vacuum pump failure.Pipeline leakage: vacuum system connecting pipes (metal pipes or rubber pipes) corrosion, aging and water leakage.Distributor head leakage: wear or poor sealing.Leakage of ceramic plate: rupture of ceramic plate.Other reasons.
- Q:Common troubles of ceramic filter
- Ultrasonic cleaning, ceramic filter plate cleaning is not clean. The main reason is that the power box is faulty, the power supply is burned out, the line is aging, the energy head is burned out, the ultrasonic box is broken down, and the water level in the pulp tank is too low;
- 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: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:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
- Ceramic filter is mainly ceramic filter plate and vacuum system, ceramic filter plate is mainly product size of ceramic plate is a new, different manufacturers of different sizes; the vacuum system can be gradually investigation vacuum components and pipelines.The ore concentration, fineness and the concentration distribution in the slurry tank are different.A ceramic filter is composed of a plurality of system, more prone to such an unknown problem, fortunately: good!
- Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
- Replace ceramic filter plate:Different users because of pulp particle size and different characteristics, the service life is long and short of ceramic filtering plate. For the use of a long time and after the method 1 and 2, the effect of slurry suction is still very poor, we should consider replacing the new ceramic filter board.
