Extruded ceramic filter

Application: Grey iron, ductile iron, aluminum alloy and other non-ferrous alloys.

NINGXIN ECF filter can effectively remove inclusions and eliminate turbulence in the metal stream. Mullite-based ceramic material with a dense network of perfectly cells to withstand thermal shock and extreme pouring temperatures.The cellular design also provides an engineered balance between flow rate and strength.Our extruded ceramic filters have excellent properties of good thermal stability, high specific surface area and resistance to acid and alkali. They are applicable to wide and extensive foundry filtration applications and processes.

Product features:

-Decrease the impurity of molten metal

-Deduce the turbulence of molten metal

-Improve the castings mechanical properties

-Decrease machining cost and improve the cutting characteristics

-Improve casting quality and yield

Q: What are the poor filtration effects of vacuum disc filters?: With the increase of the material level of the ceramic filter trough, the suction time of the ceramic filter plate in the vacuum zone increases, the thickness of the slurry increases and the productivity increases. But the drying time is relatively short, the water content of the concentrate will be increased. Select the best material level to ensure the production capacity and concentrate moisture requirements.

Q: How many degrees does the ceramic filter melt?: You should say clearly what ceramic you useHowever, as a melting furnace or filter medium, alumina products are the most versatile, but also silicon carbide, corundum, mullite, spinel and so on. They use very high temperatures.

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: Why does not the iron filter of the ceramic filter work?: The ore condition has changed, such as high concentration of material, fine grain size and increase of mud content.

Q: Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?: In unit time, the more turns of the drum, the greater the centrifugal force, the greater the rate of filtration in unit time, that is to say, the amount of filtrate in unit time is moreRotating drum vacuum filter, the greater the speed, the greater the filtration rate, but the shorter the time each turn, the amount of each filtrate will be reduced

Q: The working principle of ceramic filter: The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.

Q: What is the reason that the ceramic filter does not absorb mineral powder?: There may be a fault filtrate pump, diaphragm pump damage, pump mechanical seal failure, a leak, two is no output or output to the liquid, the pressure is too low, the cleaning effect is not good, the pressure is too large, will cause damage and reduce the concentration of slurry filter plate.

Q: How can I avoid the backwash pressure in the production of ceramic filter?: The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.

Q: What's the acid of the ceramic filter plate?: Ceramic filter automatic control system: control system through the metering pump will be concentrated nitric acid automatic mixing ceramic filter plate into nitrate after proportioning through the pipeline, so that it can be dissolved, dredge the blockage in the most microporous ceramic filter plate. This is the ceramic filter plate pickling, pickling, acid dosage should be sufficient as little pickling effect.

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.
