[0027] Through the above technical solution, when the roaster flue needs to be sealed, the front end of baffle 1 is wrapped and overlapped, so that two jacks 11 coincide, then plug rod 3 is inserted into jack 11, operator 6 holds operating rod 2 with one hand and holds baffle 1 with the other hand, then the wrapped baffle 1 is inserted into probe hole 5 by operating rod 2, then baffle 1 is attached to the sealing area of roaster, based on the negative pressure generated in the roaster, baffle 1 can be adsorbed on the cross wall of the roaster, in this case, operating rod 2 can be taken out of probe hole 5.

[0028] The combination of the high-temperature-resistant baffle 1 and the metal operating rod 2 realizes effective sealing of the flue. The operating rod 2 is designed to be longer than the baffle 1 and is provided with a plug rod 3 and a spacing to facilitate flexible movement and fixation of the baffle 1. The baffle 1 is tightly adsorbed on the cross wall by utilizing the negative pressure in the roasting furnace, ensuring the sealing effect, effectively preventing gas leakage, and ensuring the stability of the roasting process. And it reduces heat loss and improves energy utilization efficiency. At the same time, it can also reduce the production safety risk caused by poor sealing.

[0029] Roasting production often needs to be carried out under specific negative pressure conditions. This sealing method can quickly and effectively seal the flue, ensure the stability of the required negative pressure, establish or maintain the stability and safety of the roasting process of the roasting furnace, help to reduce heat loss and energy waste, thereby saving power consumption and reducing production cost.

[0030] In an embodiment provided in the present disclosure, the spacing between the operating rod 2 and the plug rod 3 is L, and the thickness of the baffle 1 is h, wherein L>2h. Based on this structure design, it is ensured that after the plug rod 3 is inserted into the baffle 1, there is enough space between the operating rod 2 and the baffle 1 for flexible movement, while ensuring the stability of the baffle 1 during overlapping and movement.
