A steam rotary kiln with supporting structure

Abstract

The embodiment of the present invention discloses a steam rotary kiln with a support structure, which includes a kiln outer cylinder, and the inner side of the kiln outer cylinder is provided with a heat-insulating filling layer surrounding the inner wall of the kiln outer cylinder, and the heat-insulating filling layer Several heating pipes distributed around the heat-insulating filling layer are installed in the inside of the heat-insulating filling layer, and the inner layer of the heat-insulating filling layer is provided with a supporting inner cylinder that is attached to it and resists the several heating pipes. The inner side of the inner cylinder is provided with a supporting turning mechanism that supports the inner wall of the supporting inner cylinder and automatically turns over the material as the kiln outer cylinder is turned over. While the inner cylinder prevents it from sagging, its turning mechanism facing inward will continue to turn up the accumulated materials from the bottom layer with the rotation of the rotary kiln, which plays a role in enhancing the calcination effect of the device; by setting the supporting turning structure as a splicing type The structure reduces the difficulty of device replacement.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of rotary kilns, in particular to a steam rotary kiln with a support structure. Background technique [0002] Rotary kiln refers to a rotary calcining kiln, also known as a rotary kiln. Its shape is similar to a rotary bed and belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. The rotary kilns currently used are generally round. The cylindrical rotatable structure is heated and calcined by arranging a heating pipe arranged around the rotary kiln in the heat insulation layer, and an inner cylinder for transferring calcined materials is arranged inside. [0003] The existing rotary kiln still has the following shortcomings in the use process: [0004] (1) Since the thermal insulation filling layer is generally a solid such as gypsum powder, it is inevitable t...
