CF series candle stick filter
Integrated with multiple filter with a kindle multi holes, with maximum filter space. When the dirt cake of the multi-hole kindle reaches a certain thickness, PLC provides signal feedback to control input of material, and remove the remained residue in the filter. Filter components can be used repeatedly. Auxiliary such as diatomite and activated carbon can be directly added to the material mud, to fasten filter speed and make the liquid more clean. This series is applicable in special cases such as high accuracy, high viscosity and high temperature.
roduct introduction
CF series candle stick filter (CF filter) is an efficient, energy-saving and automatic closed filtration precision equipment. Internal integration high-performance tubular filter more yuan, supporting tube position is according to the characteristics of material liquid choose of special filter cloth, when liquid after filtering cloth, outside the filter cloth surface gradually bypass offer solid substances in the liquid, when these solid material reaches a certain thickness is formed the so-called "filter cake layer", thus forming precision filtration.
After filtering to a certain pressure difference, after emptying the liquid, reverse blow off the filter cake, the filter element can be reused. When the filter cake layer over a certain thickness, PLC instruction signal control feeding (stop), then in net filter residual liquid, after row of net PLC signal control counter blowing mouth to blow, and the filter cake, blow after a certain time, open the filter row slag for slag discharge, discharge after close the discharge port, back to the initial state before filtering, ready for the next round of filtering.
CF filter has a wide range of use, large filtration area, no strong ability, easy to reverse filter cake, automatic operation of prominent characteristics. CF filter has direct filtration, the precoat filters, slurry concentration, filter cake, filter cake washing five big functions, can be applied to high content of impurities, viscous liquid, high precision, high temperature and so on a variety of special filter occasions.
The company adopts the international advanced microcomputer control technology, the original technology design, the seiko manufacture, realizes the whole machine system fully automatic operation, safe and reliable. It can be used for many special filtration occasions such as high content, viscous liquid, high precision and high temperature.

Working principle
Open the "feed valve", start the "material pump", the liquid is injected into the filter chamber, and the top "exhaust valve" on the top of the filter will open automatically to discharge the air inside the filter chamber. When the filter cavity is filled with liquid, the exhaust valve automatically shut down, "circulating valve automatically opens, raw material tank liquid through" into the liquid valve "into the filter, from" circulating valve "back into the material tank, loop filter, filter cake layer on the produce and gradually thickening.
When the filter cake layer reaches a certain thickness, the filtrate becomes clear. Filtrate by the automatic testing or sampling inspection to achieve quality requirements, "circulating valve automatically shut down," "clear liquid valve automatically opens, formal filter, filter the liquid to the" tank ". When the flow rate is less than a certain value, the filter needs to be cleaned. First, the "positive inlet valve" is automatically opened, and the "feed valve" is automatically closed, and the fluid is filtered out in the filter chamber. When the liquid in the filter chamber is completely filtered out, the "drain valve" will be opened, so that the residual liquid in the lower part of the filter cavity cannot be filtered through the "drain valve" to be discharged into the raw material tank. (when the technological requirements will not allow fluid backflow to the "raw material tank, don't open the drain valve, but start the residual liquid pump, sending the residual liquid pump to" residual liquid spray mouth "injection filter, from" positive inlet valve "filling the compressed gas will spray residual liquid filter out to" tank ". When the "residual liquid flowmeter" detects no residual fluid in the cavity, the residual liquid filtration system is automatically closed and the drainage work is completed. When all the fluid in the filter chamber is drained, close the drain valve and fill in the compressed gas from the "positive inlet valve" to open the "cleaning valve" or "circulation valve" to discharge the compressed gas. The filter cake is quickly dried through the compressed air of the filter element.
After the filter cake drying, close "is inlet valve", "clear liquid valve" or "circulating valve, open the" blow valve is "filled with compressed air, filter bag, filter cake off, then close" blow valve ", open the "blow air bleeder" exhaust, filter bag retraction. This process is repeated several times, the filter cloth on the filter cartridge repeatedly expands and contracts, so that the filter cake quickly falls off.
When the exhaust valve is opened, the discharge valve is opened and the filter cake residue is removed. When the discharge valve is blocked or the discharge is not smooth, open the "auxiliary discharge valve" to fill the compressed air and promote the slag discharge. After discharge, the "discharge valve" and "auxiliary discharge valve" close, open the "cleaning valve" to inject the cleaning fluid, open the "drain valve", discharge the cleaning fluid. The filter cloth will restore the filtering effect after repeated washing in the cleaning fluid. (choose different cleaning fluid and cleaning method according to the chemical properties of materials)
Note: inlet valve, outlet valve, filter cartridge valve, drain valve, discharge valve, positive inlet valve and backblow valve are basic configuration. Circulation valve, blow-back purge valve, cleaning valve, auxiliary discharge port, residual liquid treatment port, residual spray nozzle for users to choose the configuration.
