Q:What are the materials that make up the ceramic mold?
From the development trend of rice, the development of ceramic membrane preparation technology mainly in the following 2 aspects: one is the porous membrane research, to further improve the already commercialized inorganic ultrafiltration and microfiltration membrane, nanofiltration membrane with molecular sieve, the development function of gas separation membrane and pervaporation membrane: two in dense membrane research solid electrolyte membrane, ultra-thin metal and its alloy film and ion conduction ability is research hotspot. The commercial porous membranes are mainly ultrafiltration and microfiltration membranes, and their preparation methods are mainly particle sintering and sol-gel. The former is mainly used for making microporous filter membranes, and commercial A1203 films are prepared by particle sintering method.
Q:How much is the accuracy of 50nm ceramic membrane filtration?
50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.
Q:What is the reason that the ceramic filter does not absorb mineral powder?
The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
Q:Ceramic filter cleaning, sulfuric acid cleaning
Ceramic filter medium is ceramic, ceramic generally resistant to strong acid, alkali, cleaning, it is best to use nitric acid, hydrochloric acid next, not recommended to use sulfuric acid.
Q:Common troubles of ceramic filter
(1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;
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's the reason for high water content in filtration copper concentrate?
Ceramic filter plate1) the service life of the ceramic filter plate has arrived.2), ceramic filter plate uneven in quality on the market, the production capacity of some ceramic products difference (table mask size is too large or pore size uniformity is poor as a result of suction effect is poor, short life), but the price is low, but some users in order to reduce the operation cost of ceramic machine, tend to choose low price the ceramic plate, sometimes a ceramic machine ceramic filter plate with several may be different, so do not get the expected effect in normal use.In addition, the concentrator slurry, especially metal slurry, is very powerful on the wear of ceramic filter plate, the mechanical strength and wear resistance of ceramic filter plate requirements (corundum has high mechanical strength, good abrasion resistance, especially suitable for metal slurry dehydration).When selecting ceramic filter boards, these two points should be taken as a reference.
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: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:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
Water glass is a kind of adhesive of flotation reagent, after use may cause the pulp viscosity increased, leading to the adsorption resistance of slurry becomes large, when using ceramic filter filtration dewatering, vacuum suction surface of the microporous ceramic filter plate is smaller than the resistance, there may be a suction effect or even not suction. Some flocculant agents can lead to this phenomenon.
