APPLICATION:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent
resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas
and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings,
less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

-Reduce scrap related to inclusions.

-Reduce costs related to inclusion defects.

-Increase productivity with higher extrusion or rolling speeds.

-Increase casting flexibility with easy alloy changes.

-No holding metal.

Q: The ultrasonic wave of ceramic filter is not good. What's going on?: In ancient China, filtration technology was applied to produce paper made from plant fibers in 200 bc. The paper method was improved in AD 105. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp stay on the bamboo surface, after drying into paper.

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: The ceramic filter plate is broken. What will happen to the vacuum pump?: At this time, take the filtrate (this is not the first water slurry) will pollute the ceramic filter pipe, friction ring, filtrate pump, may damage the vacuum system, remaining in the pipeline in the pulp will recoil pressure under the action of pollution caused by the other ceramic plates, ceramic plates blocked him. Once the ceramic plate is broken (depending on the severity), it will make the vacuum distortion, resulting in ceramic filter suction effect worse or even no suction!

Q: Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?: The spindle speed is too fast.The speed is too high to absorb the filter cake.There are other possible reasons.

Q: The efficiency of ceramic filter is low. What's wrong with it?: CleanThe cleaning of ceramic filter is divided into two parts: reverse flush cleaning (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board.Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure.Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.).

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 is the reason that the ceramic filter does not absorb mineral powder?: There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.

Q: What is the reason that the whole ceramic filter does not attract ore?: Vacuum system failure, no vacuum or vacuum can not meet the requirements. Should check the vacuum pump and vacuum piping, distribution head, ceramic plate, such as failure or leakage.Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..

Q: What about the leakage of the ceramic filter static and dynamic sealing points?: 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.

Q: How to determine the quality of ceramic fiber filter board simply?: Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
