Definitions

• the invention is directed to a method for arranging internals in material guide tubes of heat treatment devices for powdery to granular, free-flowing, optionally slurried material that can be rotated about an axis and are heatable and coolable from the outside.
• Rotary tubes or tubes of rotary drums with tube bundles with indirect heating for the heat treatment of powdery to lumpy, free-flowing material quite often have such small diameters that it is no longer possible to crawl in to insert and fix them.
• half-pipes were previously used, which were welded together after welding or riveting the internals. This procedure is very complex and often causes difficulties due to the manufacturing tolerances of the half-tubes.
• a particular disadvantage is that the wear of the internals inside the pipe only is difficult to control and that, above all, defective parts cannot be replaced without cutting the pipe. It is also not possible to adapt the equipment for the consecutive heat treatment of different goods with regard to the built-in elements in the material guide tubes to suit the particular goods to be treated.
• the task is to provide a method with which internals can be arranged in Gut Replacementsrohre heat treatment devices such that the assembly is quick and easy, that close tolerances can be maintained to improve the heat transfer and that the internals are easily interchangeable.
• the object is achieved in that the internals for each tube are prefabricated as a unit and, as such, are inserted into the tube and fastened interchangeably.
• the installation unit can be welded, riveted or screwed together from individual parts, if necessary with the aid of devices. It is preferably provided with fastening elements at its ends and can be inserted and fastened into the crop guide tube without difficulty.
• the installation unit is used during prefabrication is larger in diameter than the free pipe cross-section and is machined to the inside diameter of the pipe before being introduced into the pipe.
• the tubes have fins on their outside for better heat exchange, e.g. B. longitudinal ribs or transverse ribs.
