Abstract
Description
Technical Field
[0001] The utility model relates to a digester delivery bin pump feed anti-blocking device. Background Art
[0002] The lime dry digestion system adopts a horizontal double-shaft stirring dry digester. Its working principle is: when adding quicklime powder, digestion water is added through a metering water pump, and the lime powder and digestion water are evenly mixed by stirring with paddles. The digested Ca(OH)2 dry powder is fed to the buffer bin through a spiral feeder, and then to the silo pump through a feed valve, and is pneumatically conveyed to the slaked lime silo. However, because the silo pump's ash conveying process goes through feeding, exhausting, discharging, and blowing, the feed valve is not kept in a normally open state, and there is a blockage or poor discharge when feeding again.
