What are the characteristics of the multi-column self-cleaning filter？
1. Self-cleaning function: This machine uses the clear water filtered by itself to self-clean the filter column. It does not need to remove the filter column for cleaning, and does not need to configure an additional cleaning system.
2. Continuous water supply function: several filter columns are installed in the tank of the machine to work at the same time. When backwashing, each filter column is cleaned one by one, and the other filter columns are still working, so as to realize continuous water supply.
3. Automatic backwashing function: The machine monitors the pressure difference between the clear water area and the muddy water area through the differential pressure controller. When the pressure difference reaches the set value, the differential pressure controller outputs a signal, and the backwashing mechanism is controlled by the electric control box to start And close, to achieve automatic backwash.
4. High-precision and reliable filtration: The filter column of this machine is made of trapezoidal cross-section stainless steel wire wound and welded on a multi-ribbon frame, which has high strength and corrosion resistance. A precise filter gap and a V-shaped area facing the direction of the liquid are formed between every two adjacent steel wires to collect particles larger than the gap to form a filter layer, thereby further improving the filtration accuracy. The V-shaped area also provides an appropriate release angle to facilitate the smooth removal of impurities during backwashing.
5. Large filtering area: the machine is equipped with several filtering columns in the whole space of the tank body, making full use of the filtering space. The effective filtering area is generally 3 to 5 times that of the inlet area, the backwashing frequency is low, the resistance loss is small, and Significantly reduces the size of the filter.
6. The backwash mechanism is reliable: the tank body of the machine is divided into a clear water area and a muddy water chamber. The backwash suction cup and filter column are installed in two chambers. The two chambers are separated by a partition, and the suction cup is close to the smooth partition. On the plate, because it does not contact with impurities, the backwashing mechanism is reliable and durable.
7. Safe operation: The machine is designed with a safety protection clutch to protect the machine from being damaged in time when it encounters overload resistance during backwashing work.
