Electric Scraper Self-Cleaning Filter

Product Introduction

The electric scraper self-cleaning filter is an advanced filtration device specifically designed for high-precision and continuous online filtration. It efficiently removes suspended solids, sludge, colloids, and other impurities from high-viscosity liquids. The filtration precision ranges from 25 to 3000 microns, making it suitable for a wide variety of industrial applications. This filter is commonly used in petrochemical processing, metallurgy, food and beverage production, and wastewater treatment.

Working Principle

The electric scraper self-cleaning filter operates by allowing liquid to enter through the inlet and pass through the filter element, where impurities are trapped on the outer surface. A motor-driven scraper continuously moves along the filter element, scraping off particles and sludge. The removed contaminants are collected at the bottom and periodically discharged through the drain valve. This automatic cleaning process occurs without interrupting the filtration operation, maintaining a consistent flow and pressure.

Material Composition

The electric scraper self-cleaning filter is constructed from durable and corrosion-resistant materials to ensure longevity and performance:

• Filter Housing: Stainless Steel (SS304/SS316L) or Carbon Steel with Anti-Corrosion Coating

• Filter Element: Stainless Steel Wedge Wire or Perforated Screen

• Scraper Blades: Stainless Steel with High Wear Resistance

• Motor and Scraper Mechanism: Robust Gear Motor for Consistent Operation

• Seals and Gaskets: NBR, EPDM, or PTFE for secure sealing

• Control Unit: PLC-based automated control system

Applications

The electric scraper self-cleaning filter is widely utilized in various industries requiring precise and efficient filtration of high-viscosity liquids:

• Petrochemical Industry: Filtration of heavy oils and sludge

• Metallurgy: Filtering cooling and lubricating fluids

• Food and Beverage: Removing impurities from syrup, sauce, and thick liquids

• Wastewater Treatment: Sludge dewatering and industrial effluent filtration

• Chemical Processing: Filtering viscous chemical solutions

• Pulp and Paper: Filtration of slurry and process water
