1.Product Description of ceramic foam filter
Characterized by high porosity,stability and excellent resistance to thermal attack
Compared with traditional filtering materials,the ceramic foam filter has obvious advantages:
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:Why should filter core be used in backwash of ceramic filter?
- Ceramic filter recoil stage is with certain pressure of clean water from the inside out washing ceramic filter plate, the outer aperture ceramic filter plate from inside is gradually reduced, such as flushing water and unclean inside contain impurities that may block ceramic filter board, other structures in the recoil stage of pollution. Such as recoil, water is not clean, you must go through the water filter cartridge to filter again, the choice of filter core, the higher the accuracy of filtration, the more clean water, but the filter is more likely to plug, scrap. Of course, the water is clean and contains little solids. The filter core is not easy to plug and even water filters can be removed.
- Q:What are the materials that make up the ceramic mold?
- At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.
- Q:How many degrees does the ceramic filter melt?
- Spinel is basically over 1600-1700. It's not too acid proof.There are other materials such as silicon nitride. Ceramics can be more than 1300 degrees in temperature. So the material you are using now is unlikely to melt and melt, and you can change it into one of the top materials. Baidu, this stuff is all over the street.
- 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
- Equipment comes with cleaning:Ceramic filter comes with a combined cleaning system, usually to ensure the normal backwash water pressure, combined cleaning (nitric acid + ultrasonic + backwash) time is sufficient, sufficient amount of nitric acid.
- Q:The ceramic filter plate is broken. What will happen to the vacuum pump?
- If it is found that the ceramic plate is broken, it should stop in time to replace the broken ceramic plate. Ceramic filter is produced by vacuum suction vacuum pump to the pulp in the water through the ceramic plate away, the surface aperture ceramic plate for several microns, so it can intercept the cake on the ceramic plate on the surface, if the ceramic plate is broken, a hole is a few millimeters, when the vacuum suction pump when they go together along with the pulp pump.
- Q:What is the backwashing pressure of the ceramic filter?
- 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 syringe pumping), and then through the scraper discharge, after unloading, ceramic filter machine is complete a cycle in the absorption 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 blockage will make the filter medium permeability and filtering effect of the loss from the poor, in order to reduce the possibility of blockage ceramic filter, will enter the backwash (this process is like a water jet injector). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
- Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
- The incoming mud content, fine particle size, pulp itself is not suitable for the use of ceramic filter dehydration, if the use of ceramic filter dehydration in this case, will accelerate the blockage of ceramic filter plate, blocking the situation after the second reference description.
- 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:What is the reason that ceramic filter does not absorb mineral powder?
- In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
