Scrapers for belt conveyors and methods for cleaning high-speed belt conveyors

摘要

Scraper system for the deflecting region of fast-running belt conveyor belts formed by a discharge drum (1), comprising a discharge drum, a belt conveyor, at least one adjustable and spring-mounted system carrier (3) transversely to the running direction of the belt conveyor, on which one or more stripping blocks (2) made of elastic material each stripping block (2) has an upper surface with a protective cap (16) made of metal, which is suitable for non-peeling on the belt conveyor belt and resiliently pressed against the belt conveyor, the system carrier (3) via a support bracket (4) on both sides of the discharge drum (1) is rotatably suspended about a support axis of rotation (5), wherein the support axis of rotation (5) by means of a spring device (6) a predetermined torque is impressed, which counter to the direction of rotation the discharge drum (1) is directed, and the support axis of rotation (5) a e rotation of the system carrier (3) by such a rotation angle that a deflection movement of the system carrier (3) can be carried out together with its Abstreifblöcke (2), wherein the one plane (18) from the central axis (M) of the discharge drum (1) and the pressure line is clamped, the other plane (19) which is applied to the pressure line on the top of the Abstreifblöcke (2), at an acute angle (γ) cuts, and wherein the other plane (19) below the central axis ( M) of the discharge drum (1). Furthermore, the combination of pre-cleaner and a suitable scraper and the associated cleaning process.
