Brief Introduction

RX precise vacuum filter combines mechanical and electric machine, ceramic tube with micro-hole and ultra-

sound to separate solid and liquid depending on vacuum suction and capillary function with high efficiency and

energy-saving equipment; they are widely used for mine, metallurgy, chemical industry and environmental protec-

tion industry.

Working Principle

Slurry-sucking district: screen plate which is dipped in the slurry will be formed into one layer of filter cake

under capillary function and vacuum pressure, the liquid will enter into distributing valve and drain tan via screen

plate.

Cleaning district: spray the filter cake after coming out of the hopper.

Drying District: filter cake will be dehydrated under high vacuum function.

Discharging district: the scraper will discharge the materials automatically under non-vacuum state.

Back-cleaning district: Ceramic plates will be cleaned from inner part to outer part by industrial water or

filtrate which is passed through distributing valve.Then the jam left on the micro-hole is cleaned. After one period

of application, ceramic board should be cleaned with ultrasonic and acid with low concentration to let the board

work with high efficiency.

Characteristics

1、High vacuum degree (0.09～0.098MPa), filter cake has low water content.

2、Solid content of liquid <25ppm, repeated application is available, drainage is lessened.

3、It can save 90% energy or above in contrast with traditional filter with low consumption and low cost.

4、Filter cake cleaning process is added to clean proper materials.

5、It combines PLC, computer and automatic valve control with high automatization and labor force has been

lowered.

6、Compact structure, covering less floor area, convenient installation and maintenance.

7、Advanced drainage system fits for any working conditions.

Introduction about RX Series of Ceramic Plates

RX whole ceramic filter plate is developed by our company through cooperating with several ceramic institutes

and absorbing foreign advanced technology, we provide our product to have high efficiency and save energy in an

environmentally friendly way. This production is mainly used for dehydration of concentrate minerals such as Gold,

Silver, Copper, Iron, Tin, Cobalt, Molybdenum, Chrome, Sulfur, Phosphorus, Aluminum, Zinc, Nickel and so on.

Also it fits for treatment of sewage and acid waste. The applicable range of materials is from -200mesh (covers 50%）

to 400mesh (covers 90%), and including micron materials. Our products have successfully won our user's confidence

due to its high separation rate, high separation precision, high operation efficiency and excellent technical economic

index, as well as extensive adaptability.

Ceramic Filter Plate is a kind of large porous ceramic disc which is fired by inorganic membrane making

technology. It has following characteristics: large filter area, high intensity and even aperture. Besides, the aperture

size can be adjusted according to actual demands. The basic material is alumina, it has good resistance to acid and

alkali. After a period of application, the ceramic filter board can be cleaned by cycle reverse cleaning, ultrasonic and

chemical cleaning agent and so on, to let the boards work with high efficiency.

Regarding firing process, traditionally the ceramic plate is consisted of two layers of plates which are glued

together to form inner channels. But after long term running, the glue will block the pores to cause "flower spots" on

the surface of the plates.

Considering this phenomenon, our company independently developed a new technology. Now the ceramic plate

is poured in one mould as a whole（We select a kind of special material, when firing under high temperature, this

material is volatilized to form the inner channels.）Thus, the "flower spots" will be avoided, also the ceramic plates

will have higher strength and not easy to be broken.

Recently, for mine production decreased obviously after several times ore absorption, our company developed a

new type of membrane surface. The porosity of the new membrane can reach 55.60%, the microporous inwalls are

smooth, and the tiny particles can pass smoothly in ore absorption process, so the jams will be reduced better.

Meanwhile, after long-term use and backwash, the regeneration ability is obvious, the service life is longer, so as to

achieve the maximum efficiency of plate surface, and improve the output.

RX 8m2 ceramic filter plate is first developed by our company through combining with foreign advanced

design idea. This plate is a large area ceramic vacuum filter plate of low energy consumption and

environmentally, which is suitable for 144m2, 204m2 and 240m2 ceramic vacuum filters. The 8m2 plate still

follows the new technology of our company, fully meet the use demand of large area ceramic filters, and ensure

the normal operation of equipments. The launch of the 8m2 ceramic filter plate (12m2 each circle) provides the

possibility and guarantee for manufacturing ceramic vacuum filters in China. At present, this 8m2 plate has

been widely used and recognized in Chile, Australia, Canada and other countries and regions. Now our

company is manufacturing 240m2 filtering equipment through cooperating with Longhai company, to meet the

market demand.

Working Principle and Application Diagram

Firstly the ceramic screen plates which are dipped in the slurry will form a thick layer filter cake on the surface

of plates under vacuum pressure. The filtrate will go through the plates and then enter into distributing valve, finally

arrive in the vacuum barrel. In the dry district, the filter cake will be dehydrated under high vacuum function to

make it further dry. After that, the ceramic plates come into discharging district, the filter cake will be discharged by

the scraper and be delivered to the required place through conveyor belt.

Finally ceramic plates enter into back- cleaning district. The filter liquid will go into the ceramic plates through

distributing valve in order to clean the jam left on the micro-holes. Thus a cycle of filter operation is finished. After a

long period of application, it can be combined cleaned by ultrasonic and chemical cleaning agent to keep the ceram-

ic filter working with high efficiency.
