Product Description:

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: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:What is the reason that ceramic filter does not absorb mineral powder?
One is leakage, two is no liquid output or output weakness, pressure is too low, cleaning effect is not good, the pressure is too large, will cause damage to the filter plate and reduce the slurry concentration. The recoil pressure is regulated by the pump loop valve and the pressure regulating valve.
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: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.
Q:What are the causes of the powder moisture in the ceramic filter?
The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
Q:How much is the accuracy of 50nm ceramic membrane filtration?
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:What's the acid of the ceramic filter plate?
General ceramic filter running for eight hours or so, you need to stop for joint cleaning, general cleaning at an hour or so. When washing together, there is acid washing, usually concentrated nitric acid. The purpose is to dissolve the pores in the ceramic filter plate through nitric acid.
Q:What about the leakage of the ceramic filter static and dynamic sealing points?
When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.
Q:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
As everyone knows, ceramic filter medium is a ceramic filter plate, microporous ceramic filter plate with a lot of distribution from the outside to the inside capillary effect, its mechanism is based on the capillary effect of microporous ceramic filter, filtration, the filtrate (generally refers to water) through these pores under the action of the vacuum suction pump, filter cake is trapped on the surface of the ceramic filter plate.
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.
