Automatic backwashing multicore water filter equipment
Backwash Cartridge Water Filter has metal filter cartridges inside. When filter elements clogged, a specially designed back-flushing arm will clean the elements one by one. When filtering, the water enters the element from both ends. When self-cleaning, the top end partly opens and the water flushed out of the bottom end.
Backwash Cartridge Water Filter has very large filter area, high flowrate, compact structure and high reliability and works better for high flowrate and dirty water filtration applications. XF auto self clean strainer has tow sub-series: M Series, for the low flowrate or filtration at rating > 300 μm. S Series, for the filtration at rating < 300 μm. Single filter flowrate range is 5~3000 m3/h. The inlet and outlet nozzle range is 2"~24"
Backwash Cartridge Water Filter is capable to remove the solid particles from water and low viscosity liquid (metal working coolant for example). XF Filter makes the fluid meet the cleanness requirement and protects the downstream key equipment from clogging, abrasing and fouling. It increases the key equipment running efficiency and service life. XF series auto self clean strainer automatically works continuously on-line; it reduces the downtime cost, maintenance cost and labor cost. XF Series auto self clean strainer is an ideal solution for water and low viscous liquid self-cleaning filtration.
Working Principle
[ Filtering ] Liquid flows into the filter via the inlet, part of liquid flows directly through filter elements from the lower ends; another part of liquid flows through the distribution pipe and into the upper part of the filter and then flows into the filter elements from the upper and lower ends at the same time,and then flows through the internal surface of filter element and goes out from the outlet. Impurities are intercepted by the elements and the filter cake slowly accumulates, which leads to gradually pressure drop increasing between the inlet and outlet. It indicates that the filter cake reaches certain thickness,and the flux of filter element becomes lower
[ Back-flushing ] When the preset pressure drop or time exceeds, the self-cleaning program is triggered. The gear motor drives the cleaning arm to aim at one element to partly cap the upper end of the element and connect its lower end to the cleaning nozzle. And then the cleaning valve opens and connect the element and discharging pipe. the differential pressure between the element's outside and discharging nozzle will make the filtrate back-flush the filter element, filter cake dislodged and be purged downward into the sewage pipe. After one element cleaned, the cleaning valve closes and the cleaning arm aims at the next one. When all filter elements cleaned, the entire back-flushing sequences are completed.
Chracteristics of SS multi-cartridge automatic backwash filter
a.it is usually used in large flow rate water with high filtration degree ,such as 50-100 micros.
b.there will be 5 to 20 or more pcs SS filter cartridges inside the filter.
c.after one day working,all filter cartridges will be backwashed by setted parameters or pressure control.
the particles which intercepted and accumulated on cartridge will be washed away.
during backwash processing,drain valve will open and particles will be outfall .
for example,backwash time for each cartdiegs will last 10 to 20 seconds.
if there are 10 pcs of SS cartridge ,backwash time will be 220 to 240 seconds.
d. after backwash,the filter will come to next filter period(usually it is 24 hours).
e.you could set the backwash circle as per practical requirement,such as twice or 3 times every 24 hours.
