AI Technical Summary
Traditional insulation methods for reactors result in slow heat diffusion and transfer within the reactor, leading to poor insulation performance, especially when handling viscous lubricants.
Multiple U-shaped tubes are fixed to the outside of the main shaft. Hot water flows through the U-shaped tubes and is driven to rotate by the main shaft. Combined with the drive motor driving the main shaft and U-shaped tubes to rotate, the heat is fully diffused in the vessel. The contact time between the hot water and the vessel wall is extended by the spiral heat conduction plate, which improves the heat transfer rate.
This allows for full heat diffusion within the vessel, improving heat transfer speed and insulation effect, and ensuring uniform heating of the lubricant.
