Product Description:

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.

FEATURES:
*Superior dimensional tolerances
*Stable chemical composition
*Highest filtration efficiency
*Excellent strength
*Resistant to corrosion attack by molten aluminum and alloys
*Beveled edges and compressible gasket

Q:What is the backwashing pressure of the ceramic filter?
It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
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?
Ceramic filter boards tend to clog and acid washing is used to dissolve and dredge blockages in their pores.
Q:Microporous ceramic filter plate cleaning
Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.
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: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.
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
Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
Generally, the vacuum degree of ceramic filter is about -0.08MPa. Sufficient vacuum pressure is only a prerequisite for a good ceramic suction effect. Besides vacuum, the other factors may affect the suction effect:Vacuum display table fault, the difference between the display value and the actual data is great.
Q:Common troubles of ceramic filter
The metering pump is not working properly and backwash water into the bucket of acid. The main reason is that the metering pump is not switched on, the diaphragm is worn out, the frequency is too low, and the check valve of the acid pipe and backwash pipe is worn out.
