Q:What about the leakage of the ceramic filter static and dynamic sealing points?
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: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:Can the ceramic plate filter the hot air?
Ceramic filter by vacuum suction effect in the ceramic filter plate to cake drying purpose, ceramic filter plate needs cleaning and life, if you discover that the slurry sucking effect is poor or even grout should first consider the three aspects: the two factors of ceramic filtering plate of ceramic filter plate most likely, are fracture and hole plugging: rupture will lead to distortion and poor vacuum cleaning; plugging holes will cause the filter plate suction effect is poor even if grout, ceramic filter plugging hole, can strengthen the appropriate cleaning (such as shortening cleaning cycle, prolong the cleaning time, increase the amount of nitric acid, such as strengthening cleaning etc.) after the effect is still not improved, you should consider the life is approaching should be scrapped and replaced with ceramic filter plate new (replacement plate should not put new or different manufacturers is mounted on the same line, the most OK, complete replacement.).
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:Why should filter core be used in backwash of ceramic filter?
Ceramic filter recoil stage is with certain pressure of clean water from the inside out washing ceramic filter plate, the outer aperture ceramic filter plate from inside is gradually reduced, such as flushing water and unclean inside contain impurities that may block ceramic filter board, other structures in the recoil stage of pollution. Such as recoil, water is not clean, you must go through the water filter cartridge to filter again, the choice of filter core, the higher the accuracy of filtration, the more clean water, but the filter is more likely to plug, scrap. Of course, the water is clean and contains little solids. The filter core is not easy to plug and even water filters can be removed.
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 can I avoid the backwash pressure in the production of ceramic filter?
Recoil of the ceramic filter is on the clean water under certain pressure, from the inside out flushing blockage blockage in the ceramic filter plate on the internal pore water pressure, the recoil is generally less than 0.12MPa, the pressure is too small or no recoil recoil effect is not good.
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:How much is the accuracy of 50nm ceramic membrane filtration?
It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
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.
