A pressure controller 3 is installed on the rear side of the pressure detector 2. When the furnace pressure inside the pressure detector 2 is too high, the pressure controller 3 sends a signal. The support frame 4 is fixed on the left side of the smelting furnace body 1. A pressure control mechanism that is linked with the pressure detector 2 and the pressure controller 3 is set on the inner side of the support frame 4. Pressure is released through the pressure control mechanism. The pressure detector 2, the pressure controller 3 and the pressure control mechanism are all connected to the PLC. As attached Figure 3 and attached Figure 4As shown, the pressure control mechanism includes a first connecting wheel 11, a second connecting wheel 12, a connecting rod 13, a third connecting wheel 14, a second adjusting wheel 15, and a drive motor 16. The drive motor 16 is mounted on the support frame 4. When the drive motor 16 is turned on, the second adjusting wheel 15 is mounted on the output end of the drive motor 16. The drive motor 16 drives the second adjusting wheel 15 to rotate. The outer side of the second adjusting wheel 15 is meshed with the third connecting wheel 14. The second adjusting wheel 15 drives the third connecting wheel 14 to rotate. The connecting rod 13 is fixed below the third connecting wheel 14. The second connecting wheel 12 is mounted below the connecting rod 13. The third connecting wheel 14 drives the second connecting wheel 12 to rotate.
