High-Performance Scraper type Self-cleaning Filter

The HPS-CF High Performance Scraper Self-Cleaning Filter automatically removes particulate impurities from the surface of the filter element by fully automated mechanical scraping and enables continuous in-line filtration. The scraper filter is divided into an electric scraper filter and a pneumatic scraper filter, which are respectively used in vertical scraping and ring scraping. Different from the recoil type self-cleaning water filter, the scraper filter is not only used for water filtration, but also widely used for self-cleaning and filtering of viscous materials such as solvent, acid and alkali, polymer, paint, etc., with higher efficiency and precision range. 30-500 microns, can handle liquids with a viscosity of up to 800,000 centipoise, used in water treatment, petrochemical, metallurgy, electric power, fine chemicals, coatings, ink, paper, food and beverage, pharmaceutical, metal processing and other industries. High-performance scraper filter, fully automatic operation, high filtration precision, stable and reliable performance, it is the economical alternative to traditional manual filter or disposable filter filter, which can replace traditional filter filter in many fields. , bag filter, basket filter, vibrating screen filter, etc.

Operating Principle
Operating principle
The liquid medium inflow from the inlet, outflow from the inner surface of the filter element , and the drain outlet is on the bottom of filter element, the liquid flow out from the drain outlet ; when the surface of filter element intercepts a certain amount of impurities, the electric actuator by the pressure difference or timer to drive the scraper to rotate and scrape the impurity on the inner surface of the filter element, rotated scraper scrape the impurities and collect them at the sewage cavity , at the same time, the electronic actuator by pressure difference or timer drive the blow-down valve to pen, the liquid slag which has a high-concentration impurities flow out from drain outlet, the liquid slag can be recycled or discharged directly.

Technology Feature:
■Continuous c filtration, fully automatic operation, end of heavy filter replacement cleaning work
■ Simple structure, standard cover auxiliary lifting device, easy to operate, easy to open cleaning and maintenance
■ Straight-line scraping, or scraping around the ring scraping method, directly scraping impurities off the surface of the filter element
■ Fully automatic operation, regular cleaning or differential pressure protection cleaning by PLC control system, so that the filter element is always clean
■ Does not produce disposable filter materials, saving consumables and environmental treatment costs
■ PTFE scraper has excellent scraping effect, which significantly improves the impurity removal ability and effectively improves the filter element life.
■ Filtration pressure loss is very small, flow rate is stable, saving pipeline energy consumption, which is conducive to continuous and stable process
■ Fully sealed filtration to prevent leakage of hazardous materials, which is conducive to safe production
■ Emission waste has high impurity concentration and can be recycled to avoid loss of high-value materials.
■ Multiple module combinations and automation modes are available to meet various filtering application requirements
■ Standard international famous brand geared motor, high reliability, long service life
■ Corrosion-resistant stainless steel 316L wedge mesh filter element, the opening size is uniform and uniform, the surface is smooth and easy to scrape, high strength, long life
■ Emission waste has high impurity concentration and can be recycled to avoid loss of high-value materials.




HPS-CF series scraper filter with wedge filter element (also known as Johnson Net)， it has the following outstanding advantages:
◆ Accuracy range 50-500 microns
◆ Accurate gap width, the tolerance is less than 5 microns
◆ The material of body is 316L, strong corrosion resistance
◆ V-shaped structure, not easy to be blocked by the impurities, maintain a stable flow in long term
◆ The outer surface is smooth, the impurities is easy to scrape, and, the wear of scraper is minimal
◆ Some troublesome impurities can also be filtered, such as: sludge type impurities, soft caking impurities
◆ The surface with a special hardening wear-resistant treatment, to extend the service life
◆ high-strength structure, the mesh screen is not deformed
◆ can wear the high-intensity positive and negative pressure
