At this time, the pull ring 34 is on the side of the heating tube 5 close to the cover plate 6, and then the heating tube 5 is closed through the cover plate 6, and the catalyst is added through the connecting tube. Then, the heater inside the workbench 1 is started through the controller 9 to heat the two heating tubes 5, and then the raw materials inside are calcined. After the raw materials are heated and calcined, the cover plate 6 is opened, and then the operator can use a tool to hook the pull ring 34 to clamp and fix the pull ring 34, and then the operator pulls the pull ring 34 to separate the first slide rail 21 from the heating tube 5, and then all the raw materials are taken out together.
