Alumina Ceramic Foam Filter

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

Alumina Ceramic Foam Filter apply to improve quality of alumina alloy casting and other non-ferrous alloy casting.

l Mend structure of crystalloid

l Improve function of machine

l Commutated function

Q:What are the functions of honeycomb ceramic filters?: At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials

Q:Can the plate filter press pass through the filter plate?: Specific, it is necessary to choose the filter characteristics according to different materials. Plate and frame filter press: plate and frame filter press is an industrial realization of solid, liquid separation, plate and frame filter press is suspension, liquid-solid, liquid two phase, applied to chemical, ceramics, oil

Q:How can I avoid the backwash pressure in the production of ceramic filter?: The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.

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 vacuum degree of the ceramic filter is normal and the cake water is large: There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure

Q:Excuse me, what's the reason that all ceramic filters do 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:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems: Oxalic acid immersion:For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate.

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:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?: The ceramic filter ceramic plate ceramic microporous pumping vacuum adsorption concentrate filtration water, the adsorption parameters according to the angle of rotation, reverse cleaning process, check whether there are loopholes in the exhaust pipe, check the ceramic plate use cycle is too long.

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.
