    摘要: An apparatus for scraping solid materials from a conveyor belt comprising an elongate segmented scraper blade formed from a plurality of individual component blades which are aligned adjacent one another in a blade holder and which are supported to engage the conveyor belt under variable linear pressure, each component blade being adjustably attached by a flexible member to provide an elongate segmented scraping edge, the segments of which can independently and automatically flex to provide an elongate scraping edge which conforms to an irregular conveyor surface.

    摘要: A method for the removal of a spent catalyst from a fixed-bed reactor is disclosed, wherein a suction hose, in which a high pressure hose comprising a high-pressure nozzle is integrated, is introduced into the reactor, the catalyst is then size-reduced by water under high pressure passed through the nozzle, the catalyst/water mixture is removed under suction and is optionally collected in a separator.
