Alumina circle ceramic foam filter
The product, adopted good portiforium foam and high purity ceramic , effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant.
Advantages:
even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering.
It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.
Ceramic foam filters are different from aperture specifications from 10 to 45ppi, with different sizes and shapes.
Besides the general specification ,we can offer the product according to the customers requirements.

- Q: Is the filter plate of the ceramic filter afraid of freezing?
- The filter plate of ceramic filter is afraid of frost and should be protected.
- Q: Working principle, ultrasonic trouble and troubleshooting of ceramic filter
- It is based on the action principle of capillary pore and realizes the solid-liquid separation through the capillary action principle of the micropore. Specifically, is the use of microporous ceramic plate water impermeable properties, extraction of ceramic plate and external cavity vacuum pressure, the suspended material groove under the action of the negative pressure adsorption on the ceramic plate, solid material through the porous ceramic plate can not be trapped in a ceramic plate surface, and the liquid due to the hydrophilic effect of vacuum pressure difference and ceramic plate by entering the gas-liquid distribution device, and then discharged or recycled, so as to achieve the purpose of solid-liquid separation.
- Q: What are the poor filtration effects of vacuum disc filters?
- The concentration can change the properties of the suspension, because the viscosity is no longer constant when the concentration of the suspension reaches a certain value, and belongs to the properties of non Newtonian fluid. For the suspension of fine particles, the filter cake resistance of low concentration slurry is higher than that of high concentration slurry, so the filter performance can be improved by increasing concentration. If the concentrate concentration is high and the general treatment capacity is high, the running overflow can be used to increase the concentrate content. The concentrate concentration is too high to influence the agitation, and the high productivity can be achieved by adjusting the overflow position.
- Q: Influence factors of ceramic filter
- (1) the particle size and the distribution of the material match the microporous of the ceramic filter plate. Although the ceramic filter plate aperture is bigger, easy to suck the pulp, but easy to cause the ceramic filter board to block up.(2) the ceramic filter plate with the same ceramic filter plate with high pore permeability and high water permeability is selected with high water permeability and good slurry absorption performance. The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.
- 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.
- Q: What is the working pressure of the ceramic filter?
- Vacuum pressure or suction is the vacuum of the equipment, the size of the vacuum directly affects the effect of ceramic filter board suction (yield and water content). The vacuum system of ceramic filter consists of vacuum pumps, tanks, distribution device, ceramic filter plate and a connecting pipe is composed of ceramic filter, the vacuum pump is generally 2BV series water circulation pump, the vacuum pump vacuum limit is -0.097MPa, using a vacuum pump for a long time or vacuum system has poor sealing performance may cause a certain degree of vacuum distortion, so the ceramic filter vacuum is generally difficult to achieve in the -0.097MPa, -0.08 ~ 0.097MPa, which indicates that the vacuum degree is good, such as the vacuum degree is not up to -0.07MPa or less, the vacuum system may be an exception.
- Q: Ceramic filter cleaning, sulfuric acid cleaning
- Can be washed with chromic acid lotion. The effect is better
- 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's the acid of the ceramic filter plate?
- Ceramic filter boards tend to clog and acid washing is used to dissolve and dredge blockages in their pores.
- Q: Can the ceramic plate filter the hot air?
- The vacuum degree of the ceramic filter in the vacuum system is about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction will not be available, and the suction effect will be poor, even without suction. 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.
