Description of the drawings:
FIG. 1 is a schematic view of a structure of a tin bath according to the present invention;
fig. 2 is a schematic structural diagram of the flue of the present invention.
The specific implementation mode is as follows:
as shown in figures 1 and 2, the heating device for the tin bath by using the waste heat of the kiln flue gas comprises a first main flue 1 communicated with a kiln 8, wherein a first main rotary flashboard 1a correspondingly matched with the first main flue 1 is arranged on the first main flue 1, and a branch flue 5 and a first branch flue 6 are communicated with the end part of the first main flue 1 on one side of the first main rotary flashboard 1 a. And a second rotary flashboard 6a which is correspondingly matched with the first branch flue 6 is arranged on the first branch flue 6.
One end of the branch flue 5 is communicated with the second main flue 2, and a first rotary flashboard 5a which is correspondingly matched with the branch flue 5 is arranged on the branch flue 5. A second main rotary flashboard 2a which is correspondingly matched with the second main flue 2 is arranged on the second main flue 2. A second branch flue 7 is also communicated with the second main flue 2. And a third rotary flashboard 7a which is correspondingly matched with the second branch flue 7 is arranged on the second branch flue 7.
The tin bath 3 is arranged between the first branch flue 6 and the second branch flue 7, molten tin 3a is arranged in the tin bath 3, molten glass 3b floats on the molten tin 3a, a group of silicon-carbon rods 3c for heating are arranged on the wall of the tin bath above the molten glass 3b in a penetrating manner, and a tin bath top cover 3d covers the top end of the wall of the tin bath.
A hollow residual heat flue 4 is arranged in the tin bath top cover 3d, and the residual heat flue 4 is distributed along the length direction of the tin bath.
