Silicon Carbide Ceramic Foam Filter

Silicon Carbide Ceramic Foam filter is justdeveloped as a new type molten metal filter to decrease casting flaw in recentyears. With its characteristics of light-weight, high mechanical strength,large specific surface areas, high porosity, excellent thermal shock resistance,erode resistance, high-performance, siliconcarbide ceramic foam filter is designedfor filtering impurities from molten Iron & Alloy, nodular cast ironcastings, grey iron castings and malleable castings, etc.

CNBM silicon carbide ceramic foamfilter ischaracterized by high porosity and mechanochemical stability and excellentresistance to thermal shock and corrosion from moltenmetal. It can effectively remove inclusions, reducetrapped gas and provide laminar flow when iron molten metalfiltrated, ceramic foam filter is machined to tight dimensionaltolerance during production, this combination of physical properties andprecise tolerance make them first choice for iron molten metal filtration.

Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?: Beneficiation of ceramic filter, the technical parameters are normal, but the water will fill in groove is what reason

Q:The ceramic filter plate is broken. What will happen to the vacuum pump?: That's a good question. I hope my answer will help you.Ceramic filter ceramic plate broken, nothing more than ceramic plate plug and ceramic plate rupture, you should be the problem of ceramic plate rupture.

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:Is the filter plate of the ceramic filter afraid of freezing?: The ceramic filter plate by table and the distribution of a large number of porous capillary ceramic filter, when working in the water slurry channel is used so the microporous ceramic filter plate internal residual has a lot of water, such as low temperature, the inside of the frozen water volume will swell, causing damage to the ceramic the inside of the microporous filter plate structure.

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: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: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:Performance advantages of ceramic filter: The base is provided with a slime recovery rotor, the rotor consists of a shaft, multistage ceramic filter disc, stripper plate, multi section water connecting pipe, pipe support plate, negative pressure connecting component dynamic disk; the rotor is in the recovery of coal slime liquid tank; the ceramic filter disc by a plurality of ceramic microporous plate cavity, located on the same axis of a ceramic plate cavity communicated through the outlet connection pipe.

Q:What is the backwashing pressure of the ceramic filter?: 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:How should the static and dynamic sealing points of the ceramic filter be leaking?: When the main shaft is rotated, the filter cake is adsorbed on the surface of the ceramic filter plate and dehydrated by the vacuum generated by the vacuum pump.
