Product Description:

Ceramic Foam Filter

 

Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses . With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. 

Size available:

7", 9", 12", 15", 17", 20", and 23", with porosities from PPI 10 to PPI 60(PPI ie pores per inch).

Other special sizes could be produced on request.

 

Product Applications:

Zirconia ceramic foam filters apply to purge and filter solution of carbon steel, steel alloy and stainless steel.

Q:What happens when the pressure on the filter plate is uneven during backwashing?
The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like device, through the pump) scraper discharge, discharge will complete a ceramic filter in the absorption cycle, slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles will cause blockage of filter media lose permeability so that the filtering effect of variation, in order to reduce the possibility of blockage, ceramic filter will enter the backwash (this process is like a water jet device). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.
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?
The faster the speed is, the shorter the time required for each turn, i.e., the shorter the filtration time, the less the filtrate will be
Q:Ceramic filter capacity.
You ask too general, to say processing capacity (ie capacity), at least to provide material conditions, such as: material name, concentration, particle size distribution. In addition, the basic conditions of equipment operation should be taken into account.
Q:The ultrasonic wave of ceramic filter is not good. What's going on?
The earliest filtration was mostly gravity filtration, which was followed by pressure filtration to increase the rate of filtration, followed by vacuum filtration. The drum vacuum filter invented in the early twentieth Century realized the continuous operation of the filter. Since then, various types of continuous filters have appeared. Intermittent operating filters (such as plate and frame press filters) are developed for automatic operation, and the filtration area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.
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: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 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: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:Microporous ceramic filter plate cleaning
In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
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.
