ZHN series scraper self-cleaning strainer (ZHN filter) is a self-cleaning filter developed by nine companies, which reaches the world leading level. Remove the particle impurities on the surface of the filter by the motor drive scraper, clean continuously online, without the need of manual cleaning of the filter element, and do not produce filter consumables. 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.

ZHN filter not only used for water filtration, more widely used in solvent, acid, alkali, polymer, coating adhesive materials such as self-cleaning filter, higher efficiency and precision of the range of 30-3000 microns, can handle up to 800000 centipoise liquid viscosity, applied in water treatment, petrochemical, metallurgy, electric power, chemical, paint, printing ink, paper, food and beverage, pharmaceutical, metal processing industries. It is used to remove all kinds of hard particles and ensure the safe and reliable operation of the system. It is a new generation of energy-efficient and environment-friendly products.

ZHN filter solves the defects such as frequent blockage of traditional filters, frequent manual cleaning and serious waste material, and gradually replaces the traditional manual basket filter and bag filter in the industry.

The liquid flows from the filter inlet and flows downward to the outlet of the filter element. When the filter element surface to collect a certain amount of impurities, motor drive device for horizontal rotating cleaning filter yuan, shave their 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 the PLC control of time/pressure difference control, filtration, continuous 24-hour online does not produce filter material, without artificial frequent cleaning, saving the cost of consumables and environmental treatment costs.
• 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.
• It adopts unique v-slot filter element, unique filtering surface structure and excellent scraping effect. Filter open gap uniform, integral molding, strong and durable.
• It USES a unique PTFE scraper to remove impurities, and it is good at filtering viscous liquid.
• The concentration of impurities is high and can be recycled to reduce the loss of high value materials.
• Various control systems can be selected, powerful and efficient operation, which can meet the requirements of customers.
• A variety of modular combinations and powerful automation modes can be selected to meet various filtering requirements.
• Many international famous brand motors, reducer, compact structure, small return clearance, high precision and bearing capacity, long service life.
• The structure is simple, easy to disassemble and easy to clean.

• Unique filtering surface structure, with excellent scraping effect, uniform and uniform filtering aperture clearance, solid and durable, high efficiency and stability.
• It is made of 304/316 materials, with excellent pressure resistance, aging resistance, acid and alkali resistance and corrosion resistance.
• It has a smooth surface inside and outside. It has very little wear and tear on the scraper.
• High mechanical strength, can withstand greater pressure difference.
• It can improve the regeneration ability of anti - washing.
• There is no particle blockage, and the anti-flushing energy can be gathered during backwashing.

• Applicable fields: water treatment engineering, grease engineering, food and beverage, beer, paper water, fine chemical, petrochemical, rolling (emulsion), biological fermentation, pharmacy, etc.
