1.Production of ceramic foam filter

Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.

2. Functions of ceramic foam filter

1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;

2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;

3). Low head loss,easy operation,energy-saving;

4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;

5). Various sizes,shapes,apertures are available for kinds of foundry technique.

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: The working principle of ceramic filter: Based on the work principle of ceramic filter function of the capillary, by using porous ceramic as filter media, a large number of small capillary action with solid-liquid separation equipment design principle using microporous ceramic disc filter in negative pressure, working conditions, characteristics of the microporous ceramic filter plate with its unique water impermeable, extraction of ceramic filter plate and external vacuum cavity the differential pressure tank suspension material under the action of negative pressure adsorption in the ceramic filter plate, solid material can not through the microporous ceramic filter plate is retained on the surface of the ceramic plate, and the liquid due to the hydrophilic effect of vacuum pressure difference and the ceramic filter plate is passed into the gas-liquid distribution device (vacuum barrel) efflux or recycling so as to achieve the purpose of solid-liquid separation.

Q: Ceramic filter fineness thin mud suction is not what to do more: Users such as pulp size is too small, too much mud, after analysis, the following methods of testing, the results have improved, it may wish to try the following methods, perhaps of help:The vacuum degree is about -0.08MPa.Adjust spindle speed and increase drying time.Ceramic filter plate with suitable pore size range.Ceramic filter plate brand on the market range, its quality is good or bad, the feed condition itself is not an ideal situation, such as ceramic filter plate with the aperture to the mine conditions do not match, it will exacerbate the effects of poor, life is short.It can shorten the combined cleaning cycle, strengthen the cleaning effect and prolong the cleaning time.

Q: What is the working pressure of the ceramic filter?: Generally speaking, there are two kinds of working pressure of ceramic filter: vacuum pressure and reverse flushing pressure.

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: 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: Does the ceramic factory use hydrochloric acid?: 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. (do not recommend sulphuric acid)

Q: What is the reason that ceramic filter does not absorb mineral powder?: One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.

Q: Excuse me, what's the reason that all ceramic filters do not attract ore?: Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..

Q: How to determine the quality of ceramic fiber filter board simply?: Ceramic fiber board quality can be judged from the following aspects:1, appearance. The surface is flat and the cutting surface is well arranged, and vice versa.2 density. Press the hands, and the surface is soft and smooth.3, process. Vacuum suction and continuous production process.4, cross section, slag ball content is low.
