Background

The drying room is used for heating workpieces in the drying room, and the workpieces are generally heated by means of convection heat exchange between hot air in the drying room and the workpieces. Meanwhile, the hot air can also heat the oven body of the drying oven, the temperature rise of the inner wall plate is the highest (generally between 50 ℃ and 200 ℃), and the temperature rise of the outer wall plate is less (generally not more than 15 ℃) by arranging the heat insulation layer. The length of the chamber body can be changed due to the expansion and contraction of the wall plate on the drying room, and when the chamber body is longer, the accumulated telescopic size of the chamber body is also larger. In order to prevent the drying room body from deforming or even locally tearing due to the change of length when the drying room body expands with heat and contracts with cold, the drying room body is generally manufactured in sections, and then an expansion joint is arranged every 30 meters or so. The expansion joint compensates for changes in the length of the chamber body. Because the drying room is not only in a high-temperature environment, but also contains organic solvent or lubricating oil volatilized by heating workpieces and a mechanized conveying chain, the expansion joint not only needs to be capable of freely stretching and contracting, but also needs to be capable of being used at a high temperature for a long time and preventing hot air containing the organic solvent or the lubricating oil from leaking. The current engineering practice generally uses rectangular or circular arc expansion joints as shown in figure 1. The rectangular joint has the advantages of simple manufacture and low cost, and has the defects of concentrated welding lines at angular points, poor expansion compensation effect and easy breakage and leakage. The circular arc expansion joint has the advantages of good expansion compensation effect and high reliability, and has the defects of special equipment manufacturing, special customization and outsourcing, and high manufacturing cost.

Therefore, a new drying room thermal expansion compensation structure is provided.
