Abstract

The invention relates to a combined structure of a rotating joint, in particular to a heat conducting pipeline rotating connection moving seal device of a drying cylinder in industries such as paper making, spinning, chemical fiber, and the like, belonging to the technical field of mechanical seal. The heat conducting pipeline rotating connection moving seal device mainly comprises a shell connection supporting structure, a tail cover and viewing mirror combined structure, an external seal-compensation combined structure, a sphere floating seal pair structure, a cantilever spacer air induction pipe and a fixed syphon tube combined structure, wherein the tail cover and viewing mirror combined structure is fastened on the tail end face of a shell; the external seal-compensation combined structure is fastened in a large end face positioning spigot of the shell; and the cantilever spacer air induction pipe and the fixed syphon tube combined structure are supported in the middle of the shell and fastened at the tail end of the shell. The cantilever spacer air induction pipe and the high-strength fixed syphon tube combined structure reduce the heat energy loss, improve the heat efficiency, lower the failure rate of a user transmission mechanism and the manufacture cost, are convenient for assembly, disassembly and maintenance, lighten the weight, improve the strength, and have good stability and prolong the service life.

Description

technical field [0001] The invention relates to a combination structure of a rotary joint, in particular to a dynamic sealing device for the rotary connection of a heat conduction pipeline used for drying cylinders in papermaking, textile, chemical fiber and other industries, and belongs to the technical field of mechanical sealing. Background technique [0002] In the prior art, it is necessary to apply an indispensable drying cylinder with heat exchange function in papermaking, textile, chemical fiber and other industries. Multiple drying cylinders are contacted sequentially through process requirements, so that the coating (or paper) that is close to the surface of the drying cylinders can exchange heat between the drying cylinders. Under normal circumstances, the heat exchange medium (such as steam) is introduced through the rotary joint installed at the journal end of the drying cylinder, and condenses on the inner wall of the drying cylinder after conducting heat, and ...
