Abstract

The invention provides a sealing device for a rotary furnace outer heating jacket. A sealing device body is in sealed connection with a cushion plate (5). The sealing device comprises multiple first-layer graphite sealing blocks and multiple second-layer graphite sealing blocks which are arranged on the outer circle of the annular cushion plate (5) in a sleeving manner. In the circumferential direction of a rotary furnace body, sealed annular circumferences are formed by the first-layer graphite sealing blocks and the second-layer graphite sealing blocks correspondingly. In the axial direction of the rotary furnace body, the first-layer graphite sealing blocks and the second-layer graphite sealing blocks are arranged side by side in parallel along the axis of the rotary furnace body. The sealing device can ensure that the outer heating jacket is tightly sealed, and heating efficiency is improved.

Description

technical field [0001] The invention relates to the field of petrochemical industry or metallurgy, in particular to a horizontal rotary furnace, in particular to a sealing device for an external heating jacket of the rotary furnace. Background technique [0002] In petrochemical, metallurgical and other industries, horizontal rotary kilns are widely used in drying, reaction, heating and other operations of materials. The drying and reaction of the rotary kiln generally requires heat to be provided by the heat-carrying medium. According to whether the heat-carrying medium can directly contact with the material, it can be divided into two kinds of rotary furnaces: internal heating type and external heating type. The rotary furnace heated by the outer jacket is usually provided with a jacket on the outside of the rotary furnace body, and a high-temperature heat-carrying medium is conveyed in the jacket to provide heat for the reaction or drying process in the furnace. Under w...
