Silicon Carbide Ceramic Foam Filter

Q: The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?: How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect is poor, I hope to help you:

Q: Performance advantages of ceramic filter: The base is provided with a slime recovery rotor, the rotor consists of a shaft, multistage ceramic filter disc, stripper plate, multi section water connecting pipe, pipe support plate, negative pressure connecting component dynamic disk; the rotor is in the recovery of coal slime liquid tank; the ceramic filter disc by a plurality of ceramic microporous plate cavity, located on the same axis of a ceramic plate cavity communicated through the outlet connection pipe.

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: How many degrees does the ceramic filter melt?: Spinel is basically over 1600-1700. It's not too acid proof.There are other materials such as silicon nitride. Ceramics can be more than 1300 degrees in temperature. So the material you are using now is unlikely to melt and melt, and you can change it into one of the top materials. Baidu, this stuff is all over the street.

Q: What's the reason for high water content in filtration copper concentrate?: Vacuum: about -0.08MPaIf the vacuum required to consider other factors; such as the vacuum degree is not up to even only about -0.05MPa, it should be related to pipeline inspection of vacuum system leakage, vacuum pump damage, distribution valve failure, ceramic plate breakage, ceramic plate connecting pipe leakage may cause the vacuum is not up to, to achieve early detection and early treatment.

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.

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: 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: Can the ceramic plate filter the hot air?: The vacuum degree of the ceramic filter in the vacuum system is about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction will not be available, and the suction effect will be poor, even without suction. If the vacuum is abnormal, should adhere to the vacuum pump, vacuum connection pipe is whether the fault Water Leakage leakage, distribution valve friction sealing, ceramic filter plate is connected with the rubber tube is aging or exfoliation, ceramic filter plate rupture.
