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:Ceramic filter capacity.: 60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.

Q:Can the plate filter press pass through the filter plate?: There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.

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:The vacuum degree of the ceramic filter is normal and the cake water is large?: The vacuum degree of the ceramic filter is normal at about -0.08MPa. Under normal circumstances, the water content of the filter cake treated with a ceramic filter is about 10%, and the moisture content of the tail filter cake is about 15%. The water content of the filter cake increases with the increase of water content in the ceramic filter.

Q:What's the reason for high water content in filtration copper concentrate?: Can the cleaning of ceramic plate meet the requirement?Such as cleaning of ceramic plate is not up to the requirements, plugging holes will increase the risk of ceramic plate, ceramic plate plug serious suction effect will become worse (filter cake moisture content increased, cake thickness reduction), cleaning of ceramic plate refers to washing and cleaning.Backwash to ensure that the water filter filter water pressure in the 0.1MPa or so, at least not less than 0.07MPa or less, it is necessary to consider before the filter water pressure is low or water filter element needs to be replaced.Joint cleaning to ensure that the ultrasonic can be no trouble, every time cleaning the amount of nitric acid up to standard. If the filtration effect is not ideal, the cleaning cycle can be washed from 45--60 every 8 hours, changed to 6--7 hours and cleaned for more than 1 hours.

Q:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?: The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.

Q:Why should filter core be used in backwash of ceramic filter?: The filter in the water filter of ceramic filter is used for filtering water.

Q:The vacuum degree of the ceramic filter is normal and the cake water is large: There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure

Q:What are the functions of honeycomb ceramic filters?: At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials
