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: The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
Ceramic filter is mainly ceramic filter plate and vacuum system, ceramic filter plate is mainly product size of ceramic plate is a new, different manufacturers of different sizes; the vacuum system can be gradually investigation vacuum components and pipelines.The ore concentration, fineness and the concentration distribution in the slurry tank are different.A ceramic filter is composed of a plurality of system, more prone to such an unknown problem, fortunately: good!
Q: Performance advantages of ceramic filter
A ceramic filter for fine coal mud recovery, there is a base, the lower part of the frame is provided with a fine slime liquid trough, the fine slime liquid material groove is provided with a liquid level controller, the slime liquid material at both ends of the groove is provided with a negative pressure water tank, the water tank is provided with a negative pressure suction connection assembly fixing the other side is provided with a vacuum pump pipeline, the pipeline is communicated with a vacuum pump and vacuum pump;
Q: What are the poor filtration effects of vacuum disc filters?
The concentration can change the properties of the suspension, because the viscosity is no longer constant when the concentration of the suspension reaches a certain value, and belongs to the properties of non Newtonian fluid. For the suspension of fine particles, the filter cake resistance of low concentration slurry is higher than that of high concentration slurry, so the filter performance can be improved by increasing concentration. If the concentrate concentration is high and the general treatment capacity is high, the running overflow can be used to increase the concentrate content. The concentrate concentration is too high to influence the agitation, and the high productivity can be achieved by adjusting the overflow position.
Q: What's the reason for high water content in filtration copper concentrate?
Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.
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: Common troubles of ceramic filter
(1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;
Q: What is the working pressure of the ceramic filter?
The backwash pressure is the size of the backwash of the ceramic filter during recoil stage, and the recoil pressure is generally less than 0.12MPa. The greater the pressure, the better the recoil effect, the better the service life and the suction effect of the ceramic filter plate, and the worse the service life and the suction effect of the ceramic filter board. The backwash pressure of the ceramic filter shall be no less than 0.07MPa.
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: The vacuum of ceramic filter is not enough
The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).
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.
