- Q: What happens when the pressure on the filter plate is uneven during backwashing?
- The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like device, through the pump) scraper discharge, discharge will complete a ceramic filter in the absorption cycle, slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles will cause blockage of filter media lose permeability so that the filtering effect of variation, in order to reduce the possibility of blockage, ceramic filter will enter the backwash (this process is like a water jet device). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
- Q: Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
- The filtrate is not discharged smoothly.The filtrate can not be discharged in a timely and smooth manner, the new filtrate can not be sucked out, and the filtrate can not be continuously sucked out, so that the filter cake can not be adsorbed on the ceramic plate.
- 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: What are the materials that make up the ceramic mold?
- Ceramic membrane, also known as CT film, is one of the solid membrane, the earliest by Japan's large Japanese printing company and Toyo ink company in 1996, the introduction of the market. The ceramic coating is mainly A12O3, Zr02, Ti02 and Si02 of inorganic materials such as porous membrane preparation, the pore size of 250mm. Has good chemical stability, acid resistance, alkali resistance, solvent resistance, high mechanical strength, can reverse flushing: anti microbial ability: high temperature, narrow pore size distribution, higher separation efficiency characteristics, has been widely used in food industry, biological engineering, environmental engineering, chemical industry, petroleum chemical industry, metallurgy industry etc. The market sales, with an annual growth rate of 35% growth. Compared with plastic products of ceramic membrane with similar high cost, but also has many advantages, it is hard to withstand strong, durable, not easy to have chemical resistance village, invasive and high temperature liquid cleaning liquid has a stronger ability to resist, its main drawback is the price expensive. _ complex manufacturing process
- Q: Ceramic filter cleaning, sulfuric acid cleaning
- Can be washed with chromic acid lotion. The effect is better
- Q: Excuse me, what's the reason that all ceramic filters do 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: The vacuum of ceramic filter is not enough
- Maybe the vacuum meter is broken. It doesn't show or show the data is different from the actual data.It could be the source of the vacuum, the vacuum pump failure.Pipeline leakage: vacuum system connecting pipes (metal pipes or rubber pipes) corrosion, aging and water leakage.Distributor head leakage: wear or poor sealing.Leakage of ceramic plate: rupture of ceramic plate.Other reasons.
- Q: What are the functions of honeycomb ceramic filters?
- High quality and high density straight hole mesh, the product has high heat resistance and impact resistance properties of cast high fever temperature, design straight hole to guarantee the balance between strength and flow, effectively remove impurities and slag particles, the mechanical properties of casting, the surface quality and the qualified rate of products is greatly improved.
- Q: Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
- Beneficiation of ceramic filter, the technical parameters are normal, but the water will fill in groove is what reason
- 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.
