Q:What is the filtration accuracy of 50nm ceramic membrane?
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 are the causes of the powder moisture in the ceramic filter?
Generally, the ceramic filter is used to filter iron powder, and the water content of the filter cake is about 10%.
Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
The ceramic filter ceramic plate ceramic microporous pumping vacuum adsorption concentrate filtration water, the adsorption parameters according to the angle of rotation, reverse cleaning process, check whether there are loopholes in the exhaust pipe, check the ceramic plate use cycle is too long.
Q:The efficiency of ceramic filter is low. What's wrong with it?
Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency.
Q:What's the acid of the ceramic filter plate?
Ceramic filter automatic control system: control system through the metering pump will be concentrated nitric acid automatic mixing ceramic filter plate into nitrate after proportioning through the pipeline, so that it can be dissolved, dredge the blockage in the most microporous ceramic filter plate. This is the ceramic filter plate pickling, pickling, acid dosage should be sufficient as little pickling effect.
Q:What about the leakage of the ceramic filter static and dynamic sealing points?
The filtrate pump works to drain or recycle the water that has been pumped out. 6 、 cleaning system work, cleaning system includes backwashing (water pump pressure or height difference pressure), acid liquid (metering pump, automatic acid injection), ultrasonic (ultrasonic work), etc.. 7 、 control system and other electrical systems. In addition, the filter cake which is absorbed and dried on the ceramic filter plate is unloaded automatically by the scraper and then falls on the belt conveyor, and is conveyed to the concentrate storage yard by a belt conveyor. Other questions about ceramic filter, welcome to chat with me or look at my head
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?
In unit time, the more turns of the drum, the greater the centrifugal force, the greater the rate of filtration in unit time, that is to say, the amount of filtrate in unit time is moreRotating drum vacuum filter, the greater the speed, the greater the filtration rate, but the shorter the time each turn, the amount of each filtrate will be reduced
Q:Can the ceramic plate filter the hot air?
Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency. I hope the following analysis will help you. First, the reasons for the ceramic filter.
Q:Is the filter plate of the ceramic filter afraid of freezing?
The filter plate of ceramic filter is afraid of frost and should be protected.
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.
