Q:The ultrasonic wave of ceramic filter is not good. What's going on?
In ancient China, filtration technology was applied to produce paper made from plant fibers in 200 bc. The paper method was improved in AD 105. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp stay on the bamboo surface, after drying into paper.
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: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:What is the reason that the whole ceramic filter does not attract ore?
Vacuum system failure, no vacuum or vacuum can not meet the requirements. Should check the vacuum pump and vacuum piping, distribution head, ceramic plate, such as failure or leakage.Whether the ore conditions are changed, such as pulp type, mud content, fineness, concentration, etc..
Q:What is the backwashing pressure of the ceramic filter?
It should be said that the ceramic filter backwash, usually with a certain pressure of clean water to backwash.
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: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 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
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:The vacuum of ceramic filter is not enough
The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).
