Silicon Carbide Ceramic Foam Filter work at more than 1500 Degree Celsius, filter moten iron and copper in related casting.


Silicon Carbide Ceramic Foam Filter

Ceramic Foam Filter is the third generation filter, compared with traditional filtering materials(ceramic honeycomb filter, extruded filter), our Ceramic Foam Filter have the advantages as below:


1. High thermal stability, stable chemical composition in high temperature,avoid the chemical reaction with the filtered molten metal.


2. High mechanical strength, large specific surface,efficient in purifying the metal flow.


3. Lower the filtering head loss,easy-operating,save energy. Smooth the metal flow,avoid the spray, spatter and backset,improve the exterior quality of the casting product,prevent the pore disfigurement,reduce the inferior rate.


4. Various size, shape and  aperture,suitable for  kinds of casting technique.

The Ceramic Foam Filter are widely used in non-ferrous metal smelt, Foundry Industrial of Copper, Aluminum Alloy, Cast Iron, Cast Steel and high temperature fume separator, special filling. silicon carbide ceramic foam filter been used to filter molten iron and copper liquid in the iron casting industry, improve the casting product quality highly.

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 working pressure of the ceramic filter?
Vacuum pressure or suction is the vacuum of the equipment, the size of the vacuum directly affects the effect of ceramic filter board suction (yield and water content). The vacuum system of ceramic filter consists of vacuum pumps, tanks, distribution device, ceramic filter plate and a connecting pipe is composed of ceramic filter, the vacuum pump is generally 2BV series water circulation pump, the vacuum pump vacuum limit is -0.097MPa, using a vacuum pump for a long time or vacuum system has poor sealing performance may cause a certain degree of vacuum distortion, so the ceramic filter vacuum is generally difficult to achieve in the -0.097MPa, -0.08 ~ 0.097MPa, which indicates that the vacuum degree is good, such as the vacuum degree is not up to -0.07MPa or less, the vacuum system may be an exception.
Q:What's the acid of the ceramic filter plate?
General ceramic filter running for eight hours or so, you need to stop for joint cleaning, general cleaning at an hour or so. When washing together, there is acid washing, usually concentrated nitric acid. The purpose is to dissolve the pores in the ceramic filter plate through nitric acid.
Q:What filter material are placed in the aquarium filter?
Submerged in water. Submersible pumps and filter cotton (often replaced by sponge) installed in one, and some brands will also be installed heaters, which become multi-purpose fish farming equipment. When working, the water is absorbed into the filter in many directions, and the filtered water is returned to the water tank by other means. This filter because of its low price and popular beginners of all ages, but the effects from the use of view, only suitable for small fish density, on the flow and filtration requirements are not high, a small aquarium, "fish" will be built in filter (especially the heating function of the filter for seedling and foster) water tank. The effect is very good. The biggest disadvantage of this device is that when it stops working, a lot of dirt stuck to the filter runs back into the water.
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: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:What is the filtration accuracy of 50nm ceramic membrane?
The filtration accuracy is the maximum particle size that the membrane can pass through.
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 capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
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
