Multi-Disc Filter for Environmental Protection Equipment

BS Series Ceramic FilterI. OverviewCeramic filtration is the world's most advanced solid-liquid separation technology and it has beenincreasingly widely used in various fields of national economy since it is featured by energy saving,environmental protection and the resources recycling. Ceramic filter is a model of the successfulapplication of ceramic filtration technology. Its large-scale promotion in recent years in China has broughtgood economic and social benefits. In the early 1980s, Finland's Outokumpu Company successfullydeveloped ceramic filter board that could be used as filter medium. Ceramic filter plate aperture is usually1-Sum (the most commonly 1.5~2.0um) and such micro-pore can produce strong capillary action. Whenceramic filter operates, under the action of vacuum pump, only the liquid enter through the micro-poreand become filtrate, while both solids and gases are blocked in the filter plate surface and become filtercake. In this way, it realizes solid-liquid separation.industries, extensive application fields.The emergence of new type of filtration medium is of epoch-making significance for the developmentof solid-liquid separation technology. Ceramic filtering plate can produce capillary action and hasexcellent mechanical properties, so it has a lot of advantages relatively to other filters with filter cloth as thefilter medium. Ceramic filter can be widely used in the dehydration processing of non-ferrous metal mine.coal, chemical industry, pesticide, pharmacy.II. Main Features(1) Energy-efficient: great processing capacity and obvious power saving effect. Processing capacityis more than 1100 kg/m2 • h and the electricity consumption is less than 0.5kWh/th. Compared withtraditional disc and external filter, it can more than 80% of save energy consumption.(2) Automatic control: high-performance series machine adopts automatic control program,automatic feeder and automatic cleaning, so it reduces operators'labor intensity and reduce theamount of operating personnel.(3) Perfect automatic protection function: it possesses fault automatic alarm system, fault screendisplay function, and high and low level alarm display, and can automatically exclude or shutdownartificial processing.(4) Firm structure and durable use: it adopts microcomputer optimization design, and has rationalstructure and reliable operation. Its main drive disk assembly adopts maintenance-free design that reducesoutage rate; its mixing system in tub adopts stainless steel structure, ensuring the service life can reach over10 years.(5) Improve product quality and reduce transportation cost: because concentrate water content islow after filtering processing, it can greatly improve product market competition ability, and reduce thetransportation cost and the loss in the process of transportation.(6) Obvious environmental protection effect: filtrate is clear and can be repeatedly used, so it reducesthe discharge and complies with the current trend of environmental protection and clean production.Ill. Structure PrincipleCeramic filter structure mainly includes rotor formed disc with several groups of ceramic filter plates,distributing head with suction and washing effect producing coupling switch phenomenon, mixerpreventing solid precipitation, scraper that is necessary to eliminate filtering plate solid adsorption, cleaningsystem of filter board outside the filtering plate abdominal cavity and ultrasonic oscillation, as well as thecontrol system of the tub and operation procedure keeping certain paste liquid level.During its operation, due to the effect of vacuum filter plate, when the rotation is submerged under theslurry liquid surface of groove, the surface of the filtering plate will form a solid particle accumulation layerand liquid will pass through the filter plate and enter vacuum barrel though distribution switch. When thefilter plate with accumulation layer leaves slurry liquid level, it will form filter cake. As a result of the action ofvacuum, it will continue dehydration and make the filter cake further dry.When the rotor continues to turn to the place of scraper, filter cake will be unloaded and sent to therequired place by the belt drive machine. SpecificationsFiltration area(M2)Disk NumberDisk Dismeter (MM)L*W*H (MM)Weight (T)Operating Power (KW)Volume of Tank(M3)BT6M26315202500*2200*2074261.1BT8M28415202750*2200*2074261.3BT10M210515203000*2200*207438.351.5BT12M212419203100*2650*24863.58.351.5BT15M215519203400*2650*248659.22BT20M220422103500*3000*3025510.74Our Service1.
