Abstract
PURPOSE: To control reduction of filtering capability through prevention of filter membrane clogging by a method wherein a net type holder plate of filter membrane is overlayed on the filtered liquid surface of the filter membrane having numerous cylindrical fine holes, and elastic scraper member is slided on the raw liquid surface of the filter membrane during filtering operation.
CONSTITUTION: At the center of top face of bottom container 4 of a filter device and above a net type holder plate 5, placed is a filter membrane 1 consisting of a smoothly planed membrane or thin plate having numerous cylindrical fine holes in thickness direction. A lid member 10 is provided at its shaft 9 with a scraping member 8 having scraping piece 22. These members and components are assembled so that the scraping member 8 is continuously or intermittently sliding on the surface of the raw liquid side of the filter member 8 thereby to scrape off particles, during filter operation, trapped on the surface of the filter membrane 1. Scraped and collected fine particles are discharged through discharge hole 19, hollow portion of the shaft 9, and discharge outlet 21. Filtered liquid is discharged through filter liquid chamber 28.
