Abstract

PURPOSE:To provide a scraper unit which fills a gap between spiral blades and an outer cylindrical screen so as to enable an efficient filtering and dehydrating operation an which does not shift and fall during a delivering motion in a screw press. CONSTITUTION:A series of scrapers 4, whose outer edges come into slidable contact with the inner surface of an outer cylindrical screen 3, is fitted in a series of grooves provided on the outer peripheral surface of the spiral blades 2 in a screw press. On the other hand, grooves which orthogonally cross the grooves with adequate spaces apart are provided on the spiral blades 2; and a clip striding over this groove is fixed on the spiral blade 2 at both leg ends upon piercing through the scraper 4. The scrapers 4 thus attached are fixed both in the direction along the grooves of the spiral blades 2 and in the direction moving vertically in the grooves, and are capable of efficiently scraping and sending cakes generated on the inside surface of the screen.
