Full-Automatic Candle Filter
In order to solve the environmental
pollution caused by the open-type filter and increase the
dryness of the filter cake, we developed a completely
The pressure-tight filter is
placed some candle tubes, which is suitable for different
occasions. Because there is no actuator device, and its
structure is simple, so it is suitable for an operating
condition of large filtration area. The filter device is
fully automatic operation, no any leakage.
The filter element adopts a
structure design of double plum blossom tube bank (internal
stainless steel skeleton and external filter cloth). The
middle drainage tube can help to drain the liquid in the
filter tube, and, the remaining liquid can be drained away
by the middle bleeder tube, and, the filter cake is blown
off by back flushing of clean gas, its efficiency is
obviously higher than other filter. The filter is suitable
for the filtration of impurity content of 0.1% to 50%.
◆Multi-hole filter element is dismountable
and easy to replace, clean, and maintain.
◆the moisture content of discharged slag
can be adjusted according to customer requirements, and
filter cake is very easy to be broken, can be directly
discharged into the beating tank, without the conveyor
Full pressure-tight operation, both suitable for the
filtration of general materials, can also be used for
flammable, toxic or highly toxic dangerous products, and a
fresh food which does not allow be polluted, biological
products and pharmaceuticals, etc.
◆the filter with an intelligent control
system, greatly saving labor
When the candle filter is start to its
filtering process, the slurry is fed into the filter by the
pump. The liquid phase in the slurry passes through the
filter medium and enters into the center of multi-hole
filter element, and is discharged from the outlet of the
clear liquid. Before the cake layer is formed, the
relatively clean liquid is sent to the inlet of raw material
slurry again to do a filtration process, until the filter
cake layer is formed (or meet the requirements ), and then,
the control system will give a signal to stopping the
recycle filtration. The clean liquid will be sent to next
process through the control valve and execute the normal
After a normal filtration period,
the system automatically provides a signal to stopping feed
and drain away the remaining liquid when the filter cake
layer on outside surface of multi-hole filter element is
reach to a certain thickness. And then, the control system
provides the signal again to back flushing (compressed air,
nitrogen or Saturated steam), the filter cake is stripping,
the outlet of slag is open to discharge by the control
system. Next filtration process will be executed again.
