Q: The ceramic filter plate is broken. What will happen to the vacuum pump?: At this time, take the filtrate (this is not the first water slurry) will pollute the ceramic filter pipe, friction ring, filtrate pump, may damage the vacuum system, remaining in the pipeline in the pulp will recoil pressure under the action of pollution caused by the other ceramic plates, ceramic plates blocked him. Once the ceramic plate is broken (depending on the severity), it will make the vacuum distortion, resulting in ceramic filter suction effect worse or even no suction!

Q: Influence factors of ceramic filter: Ceramic filter board, also known as ceramic filter membrane, ceramic plate, ceramic plate, filter plate, etc., is made of corundum, silicon carbide and other special process made of new filter media. At present, as the core component of the ceramic filter, ceramic filter plate has been widely used in solid-liquid separation of iron concentrate, zinc concentrate, sulfur concentrate, copper concentrate, nickel concentrate, molybdenum concentrate, lead concentrate, tungsten concentrate, manganese ore, vanadium ore, aluminum ore, gold ore, non-metallic mine Ore Concentrate Dewatering and coal, chemical industry, papermaking, pharmaceutical, chemical, food, environmental protection and other industries.

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: The efficiency of ceramic filter is low. What's wrong with it?: 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 these three aspects:Ceramic filter plateTwo factors of ceramic filter plate most likely, respectively is the rupture and plugging holes: the 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 cleaning (such as shorten the cleaning cycle, prolong the cleaning time, increase the amount of nitrate), such as strengthening the cleaning effect is still not improved, it should consider the life 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, best can complete change).Vacuum system failureThe vacuum degree of ceramic filter is usually about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction can not be provided, and the suction effect will be poor, or even the pulp will not be sucked.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.

Q: The working principle of ceramic filter: Based on the work principle of ceramic filter function of the capillary, by using porous ceramic as filter media, a large number of small capillary action with solid-liquid separation equipment design principle using microporous ceramic disc filter in negative pressure, working conditions, characteristics of the microporous ceramic filter plate with its unique water impermeable, extraction of ceramic filter plate and external vacuum cavity the differential pressure tank suspension material under the action of negative pressure adsorption in the ceramic filter plate, solid material can not through the microporous ceramic filter plate is retained on the surface of the ceramic plate, and the liquid due to the hydrophilic effect of vacuum pressure difference and the ceramic filter plate is passed into the gas-liquid distribution device (vacuum barrel) efflux or recycling so as to achieve the purpose of solid-liquid separation.

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: How much is the accuracy of 50nm ceramic membrane filtration?: The filtration accuracy is the maximum particle size that the membrane can pass through.

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?: Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..

Q: How to determine the quality of ceramic fiber filter board simply?: Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
