1.Production of ceramic foam filter
Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
2. Functions of ceramic foam filter
1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;
2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;
3). Low head loss,easy operation,energy-saving;
4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;
5). Various sizes,shapes,apertures are available for kinds of foundry technique.

- Q:What is the reason that the ceramic filter does not absorb mineral powder?
- The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
- 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:The vacuum degree of the ceramic filter is normal and the cake water is large?
- The concentration, particle size and mud content of the raw materials are not suitable for or due to changes, which are no longer suitable for dehydration using ceramic filters
- 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: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 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:The ceramic filter plate is broken. What will happen to the vacuum pump?
- At this time, take the filtrate (this is not the first water slurry) will pollute the ceramic filter pipe, friction ring, filtrate pump, may damage the vacuum system, remaining in the pipeline in the pulp will recoil pressure under the action of pollution caused by the other ceramic plates, ceramic plates blocked him. Once the ceramic plate is broken (depending on the severity), it will make the vacuum distortion, resulting in ceramic filter suction effect worse or even no suction!
- Q:What is the filtration accuracy of 50nm ceramic membrane?
- It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
- Q:Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?
- The ceramic filter ceramic plate ceramic microporous pumping vacuum adsorption concentrate filtration water, the adsorption parameters according to the angle of rotation, reverse cleaning process, check whether there are loopholes in the exhaust pipe, check the ceramic plate use cycle is too long.
- Q:What is the backwashing pressure of the ceramic filter?
- Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.
