The connecting lock buckle includes a flexible pipe, and the two ends of the flexible pipe are respectively connected to the air duct I and the air duct II; a clamping mechanism is installed at the horizontal arrangement of the chute pipe and the air duct II.

[0007] Furthermore, the clamping mechanism includes a fixing column and a locking column. Arc grooves compatible with the chute pipe and the air duct are opened on the opposite surfaces of the fixing column and the locking column. Locking bolts are correspondingly provided on the locking column and the fixing column, and a fixing part is provided at the lower end of the fixing column.

[0008] Furthermore, at least two groups of locking bolts are arranged accordingly.

[0009] Furthermore, the locking bolt is arranged as a double-headed stud, with matching locking nuts installed on both sides.

[0010] Furthermore, the fixing portion is a mounting plate welded to the lower end surface of the fixing column, and corresponding mounting holes are opened on the mounting plate.

[0011] Furthermore, quick-release clamps are provided on both sides of the flexible pipe, and are fixed to the air duct I and the air duct II respectively through the quick-release clamps.

[0019] Example 1

[0020] like Figures 1 to 3 As shown, the chute air supply duct anti-detachment device described in the utility model includes a connecting lock for the chute pipe 1 and the air duct. The air duct is arranged in sections. The air duct includes an air duct I9 connected to the chute pipe 1 and an air duct II6 arranged separately. The connecting lock includes a flexible pipe 8. The two ends of the flexible pipe 8 are respectively connected to the air duct I9 and the air duct II6; a clamping mechanism is installed at the horizontal arrangement of the chute pipe 1 and the air duct II6.

[0021] The clamping mechanism includes a fixing column 2 and a locking column 3. Arc grooves compatible with the chute pipe 1 and the air duct are opened on the opposite surfaces of the fixing column 2 and the locking column 3. Locking bolts 4 are correspondingly provided on the locking column 3 and the fixing column 2, and a fixing portion 21 is provided at the lower end of the fixing column 2.

[0022] At least two groups of locking bolts 4 are arranged to prevent rotation during installation.

[0023] The locking bolt 4 is arranged as a double-headed stud, and matching locking nuts 5 are installed on both sides. The double-headed stud can withstand a greater load and the connection is more stable.

[0024] The fixing portion 21 is a mounting plate welded to the lower end surface of the fixing column 2 , and corresponding mounting holes are opened on the mounting plate for installing anchor bolts.

[0025] Quick-release clamps 7 are correspondingly provided on both sides of the flexible pipe 8, which are respectively fixed to the air duct I 9 and the air duct II 6 through the quick-release clamps 7, making installation convenient.

[0026] Working process or working principle:

[0027] By improving the original connection lock between the chute pipe 1 and the air duct, the air duct I9 is ​​welded to the chute pipe 1, and then the air duct II6 is connected through a flexible connection. Finally, the clamping mechanism is installed and fixed by anchor bolts to reduce the vibration of the chute pipe 1, thereby avoiding the air duct from falling off, thereby ensuring the normal and stable material flow and ensuring the raw material supply of the electrolytic cell.

[0028] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
