Q:The working principle of ceramic filter
The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.
Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
First, the fineness of the material, resulting in the filter board filter cake moistureTwo, the vacuum can not reach, in the circumstances, whether the vacuum pipe leak
Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems
Selection of new ceramic filter plate:Because of the different size and characteristics of the pulp, different users need ceramic filter plates with different pore sizes (i.e., the average range of their surface pore size). In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
Q:What are the poor filtration effects of vacuum disc filters?
With the increase of the material level of the ceramic filter trough, the suction time of the ceramic filter plate in the vacuum zone increases, the thickness of the slurry increases and the productivity increases. But the drying time is relatively short, the water content of the concentrate will be increased. Select the best material level to ensure the production capacity and concentrate moisture requirements.
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:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
Q:How many degrees does the ceramic filter melt?
Alumina made from tabular corundum can be used over 1800 degrees!SiC if there is atmosphere, protection will be higher, there is no atmosphere protection, because the existence of oxidation, generally not more than 1600.Corundum, mullite, 1750 degrees small meaning.
Q:What is the reason that the whole ceramic filter does 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:What are the reasons for the program alarm of ceramic filter?
The vacuum failure may be the vacuum pump failure, the vacuum pipeline leakage, the ceramic filter plate rupture or the connection water leakage, the backwash system is generally before the filtration water pressure is insufficient, the filter core plug and so on. Vacuum suction deficiency will lead to poor effect or even suction; cleaning standards will accelerate the ceramic filter clogging, ceramic filter clogging even if the vacuum suction is normal, will not even bad effect such as cake, jelly thin with high water content. Ceramic filter plate, hole plugging, discarding. Ceramic filter plate is life, under normal circumstances is about a year, such as pulp mud content, fine particle size or containing ingredients, cleaning is not easy to precipitate standards will reduce its life, when the ceramic filter plate close to the scrap, the suction effect will be worse. I hope my answer can help you.
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.
