Seal baffle of calcining furnace

The utility model provides a sealing baffle plate of a calcining kiln, which is characterized in that two mobile cannulas are up and down sleeved on a stationary barrier pipe, and a supporting plate on one side freely rotates around the stationary barrier pipe through a connecting plate and two mobile cannulas. An operating lever is connected with the supporting plate on one side through the connecting plate, and the operating lever freely rotates around the stationary barrier pipe through the mobile cannulas which are sleeved on the stationary barrier pipe. The working principle of the utility model is that the operating lever is rotated to drive the supporting plate to move through the connecting plate, and the sealing baffle plate is led to be furled or opened. The utility model has the advantages that the sealing baffle plate greatly simplifies a framework structure, which excellently seals flues, simultaneously has very simple operation, greatly lowers labor intensity of workers, and particularly lowers
