Mining Ore Dewatering Ceramic Vacuum Filter

Main Structure

  Ceramic filter is mainly consisting of roller system, mixing system, ore slurry feed and discharge system, vacuum system, filtrate discharging system, scraping system, back washing system, united washing system (ultrasonic cleaning, automatic matching acid cleaning), full-automatic control system, trough body, rack etc.

Trough body uses corrosion resistant stainless steel, can load ore pulp. Stirring system is stirring mixing materials in trough body to avoid the rapid subsidence of materials. Ceramic filter plate is installed on roller, roller can be rotated by the drive of stepless speed change reduction gears.

Filter medium of ceramic filter is ceramic filter plate, doesn’t need filter cloth, that reduces cost of production. The 1mm gap between scraper and filter plate prolongs the service life while discharging.

Using back washing and united cleaning etc. methods, full-automatic control by PLC, equipped with inverter, liquid level meter etc. device. While starting up, ore pulp valve is monitored by level meter, it controls height of ore pulp level. When to high level, PLC control system rapidly opens filtrate pump outlet valve to drain water quickly. Ceramic can use long-range control or centralized control according to different requirement by customers.

Structure and Effect

Ceramic filter is mainly consisting of roller system, mixing system, ore slurry feed and discharge system, vacuum system, filtrate discharging system, scraping system, back washing system, united washing system (ultrasonic cleaning, automatic matching acid cleaning), full-automatic control system, trough body, rack etc. Every system components and effect as follows:

   Roller system: consisting of main spindle, roller body; one side of main spindle connects driving motor, reduction gears, another side is cooperated with distribution head; on roller body, welding with annular plate, equipped with ceramic filter plate on it; ceramic filter plate is connecting with distribution head by pipeline. Roller system is the core of ceramic filter, it completes solid-liquid separation cooperated with vacuum system.

Mixing system: consisting of driving motor, reduction gears, horizontal axis, connecting rod, crank and rake frame, under the drive of actuating device, transmit power to rake frame by the parts, the rake frame which is immersed in ore pulp reciprocating wiggles, stirring ore pulp prevent it from precipitating.

Ore slurry feed and discharge system: mainly consisting of gas control rubber valve, liquid level meter and relevant pipeline. This system is cooperated with automatic control system, feeding part controls feeding rubber valve switch automatically according to presupposed liquid level, thus controls feeding quantity. Ore discharge part controls discharging rubber valve according to requirement of cleaning technology, realized ore discharging or storing.

Vacuum system: consisting of vacuum pump, filtrate tank and relevant pipeline. While vacuum pump is operating, it is formed vacuum in filtrate tank, one side of relevant pipeline connects with filtrate tank, another side is connecting with ceramic filter plate by distribution head, those make solid matter be adsorbed on filter plate surface and filtrate be absorbed into filtrate tank.

Filtrate discharging system: consisting of filtrate pump and relevant pipeline. While filtrate pump operating, filtrate in tank discharge from pipeline.

Scraping system: consisting of scraper, scraper frame and fixed bolt. To scrape filter cake on filter plate surface is the effect.

Back washing system: consisting of filtrate pump, cleaning pipeline, filter, reducing valve, relief valve and relevant pipeline. There is interval between scraper and filter plate for alleviating its attrition. After striking off filter cake, there is a material lamina remained on filter plate surface, to ensure the filter plate efficiency, a part of filtrate is sent back by filtrate pump, to back wash filter plate through cleaning pipeline and distribution head.

United washing system: consisting of sonicleaning (including supersonic generator and ultrasonic oscillatory plate) and acid washing (including acid storing box, acid pump and washing pipeline). After a certain working time of filter plate, filtering efficiency would be reduced because of blocking and other material adhesion, at this time, regenerate filter plate by united washing.

Full-automatic control system: consisting of PLC, touch panel, liquid level meter, frequency converter, magnetic valve, air-operated valve and other electrical components. Design working, cleaning and all kinds of technical parameter of ceramic filter according to material properties and customers’ requirements, realize full-automatic control, manual control, monomer or centralized control.

Trough body: loading filter material.

Rack: load bearing other components except filtrate pump and acid storing box.
