Mechanical scraper for removing deposits from inside vessels - has associated collecting tray collecting dirt particles from upturned vessel

摘要

The deposits are removed by rotating a scraper iron. This scrapes along the base of the metal vessel which is held in a stand by two tension hoops which grip round opposite sides of the vessel jacket and by a pressure plate which adjoins the base from the outside. A collecting apron is associated with the vessel so that the scraped-off parts can be easily gathered up and removed so as not to contact and contaminate the inside of the vessel.
