Heat dissipation structure of preheating chamber roller bed

Abstract

The invention discloses a heat dissipation structure of a preheating chamber roller bed. The heat dissipation structure comprises a roller bed body located in a preheating chamber, wherein the rollerbed body comprises a roller and two sealing end covers arranged on the left and right sides of the roller, each sealing end cover comprises a rotating shaft and two mounting plates arranged on the corresponding rotating shaft, each pair of mounting plates are arranged side by side on the corresponding rotating shaft, each sealing plate located at the outer side is fixedly welded to the side end face of the roller, the center of one of the rotating shaft is provided with a through hole, one side of the preheating chamber is provided with a condensing device, and a condensing tube of the condensing device is connected to the through hole of the corresponding rotating shaft. The heat dissipation structure of the preheating chamber roller bed has the advantages that the roller can be filled with a condensing gas through a ventilation hole to reduce the temperature of the roller; a connecting sleeve arranged at the through hole can make the condensing tube cooperate with the corresponding rotating shaft well, the rotation of the rotating shaft cannot influence the installation of the condensing tube, the structure is designed simply and skillfully, the roller bed is prevented from beingthermally deformed, and the long-term use of the roller bed in the preheating chamber is ensured.

Description

technical field [0001] The invention relates to a component structure of a steel plate pretreatment line, in particular to a heat dissipation structure of a roller table in a preheating chamber. Background technique [0002] The steel plate needs to be preheated before shot blasting to remove surface water, increase the temperature of the steel, and achieve the initial effect of oxidation and shedding, so that the rust on the surface of the steel plate can be better removed in the subsequent shot blasting, and the pre-treatment During the heating process, the conveying rollers located in the preheating chamber will be subjected to very high temperature, and the roller table will be deformed due to the heat for a long time, which will affect the normal conveying of the steel plate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat dissipation structure for the roller table in the preheating chamber that can p...
