Patent Number: ZL 2016 2 0673925.7

VITHY? VAS-A series Pneumatic Scraper Filter (also called Self-cleaning Ring Scraper Filter) automatically removes particulate impurities on the inner surface of the filter element, in a way of cylinder-driven scraping. The scraper is made of PTFE. The particle impurities are scraped from top to bottom and discharged from the bottom sewage outlet. The filter is suitable for high impurity content and continuous uninterrupted production conditions, for it 1) can realize continuous in-line filtration and 2) particulate impurities recovery, 3) generates no filter consumables, and 4) does not need frequent manual cleaning.

Applicable Industries and Fluids

■ Industry: Petrochemical, fine chemicals, bioengineering, food, pharmaceutical, water treatment, paper, steel, power plant, electronics, automotive, etc.

■ Fluid: Water, fermentation broth, syrup, protein, corn steep liquor, soybean meal, culture medium, crude oil, mixed oil, methyl styrene, concentrated sulfuric acid, methanol, polymer, resin, printing ink, pigment, filler, coating material, citric acid, soap, rubber, sorbitol, wet end chemical additives, adhesive, ethanol, chocolate, high-temperature oil, fruit juice, coolant liquid, diesel, kerosene, etc.

■ Main filtering effect: Remove large particles; fixed value screening; purify fluids; protect key equipment.

■ Filtration type: Scraping filtration; automatic continuous in-line filtering.

Technical Features and Advantages

■ Automatically operating; self-clean by PLC timing or differential pressure setting, so that the filter element is always clean.

■ It does not produce disposable filter consumables, saving consumables and environmental treatment costs.

■ The PTFE wear-resistant material scraper has an excellent scraping effect, significantly improves the ability to remove impurities, and effectively extends the service life of the filter element.

■ The high-strength filter element has precise gaps, an extremely smooth surface (so it easily scrapes away impurities), and long service life.

■ The filtration pressure loss is extremely small; the flow is stable, and the pipeline energy consumption is small, which is conducive to a continuous and stable process.

■ Sealed filtration prevents the leakage of dangerous materials and is conducive to safe production.

■ The discharged waste liquid impurities have a high concentration and can be recycled, avoiding the loss of high-value materials.

■ Various module combinations and automation modes are available to meet various filtration requirements.

■ Equipped with a geared motor of an internationally famous brand or pneumatic components, it has extremely high reliability and long service life.

■ Equipped with an auxiliary lifting device on the upper cover, it is easy to operate.
