ZHW series scraper self-cleaning filter

ZHW series scraper self-cleaning strainer (ZHW filter) is an efficient self-cleaning filter developed by nine companies, which reaches the world leading level. The particle impurities on the surface of the filter are removed by the motor driven scraper, which is used to remove all kinds of high viscosity liquids and continuously clean online, without the need of manual cleaning of the filter element, and no filter consumables are produced. Control the time/pressure control by PLC, automatically eliminate the high concentration of impurities in the contaminated cavity, and eliminate the recovery and discharge of residual liquid.

ZHW filter is suitable for solvent, acid, alkali, polymer, coating of high viscosity material self-cleaning filter, higher efficiency and little pressure loss of the filter, flow stability, save energy consumption of pipeline, is advantageous to the process continuous and stable. Apply to oil, paper, petrochemical, fine chemicals, paint, ink, food and beverage, bio-pharmaceutical industry.

The liquid passes through the filter inlet, and the liquid flows through the filter screen from the outside of the filter element to the outer surface of the filter. When the external surface of the filter element to collect a certain amount of impurities, motor drive do horizontal rotating cleaning filter element, in addition to the screen surface impurities, impurity gathered in set with the descending liquid dirt cavity, when accumulated to a certain amount of impurities, dirt cavity, automatic drain valve open set will contain high concentration of impurity liquid discharge, discharge residual liquid can be recycled or emissions.

Fully automatic operation, through PLC control time/pressure difference control, continuous 24 hours of online filtering, no filter consumption, no manual cleaning, cost saving and environmental protection.
• The filter pressure loss is minimal, the flow rate is stable, and the energy consumption is saved, which is beneficial to the continuous stability of the process.
• It is fully enclosed filter to prevent leakage of dangerous material, which is beneficial to safe production.
