[0026] A gantry 1 is used to be arranged at the tail of a cement rotary kiln; a clamping assembly 2 is installed at the top of the interior of the gantry 1, and the clamping assembly 2 includes: a carrying shell 201, which is installed at the top of the interior of the gantry 1, and the two ends of the interior of the carrying shell 201 are respectively rotatably connected with toothed discs 208, the two toothed discs 208 are meshed, and the bottoms of the two toothed discs 208 are respectively fixed with extension arms 207 extending to the bottom of the carrying shell 201, and one side of the exterior of the carrying shell 201 is installed with a driving motor 202 for driving one of the toothed discs 208 to rotate; the bottoms of the two extension arms 207 are respectively rotatably connected with force-bearing folding arms 205, and the bottoms of the two force-bearing folding arms 205 are jointly installed with a heat conversion component, and the bottom end of the interior of the carrying shell 201 is respectively rotatably connected with a rotating arm 204 matching the two force-bearing folding arms 205; when the driving motor 202 is running, the heat conversion component is attached to the surface of the tail of the cement rotary kiln under the operation of the clamping assembly 2.

[0027] It should be noted that when the device is actually used, the clamping assembly 2 will automatically adjust according to the shape and size of the cement rotary kiln tail to ensure that the heat conversion component fits tightly with the kiln tail surface, thereby improving the waste heat recovery efficiency.

[0028] It should also be added that, in the present application, a control panel 3 for controlling the operation of the drive motor 202 and the heat conversion component is installed on one side of the outer surface of the gantry 1 .

[0029] like Figure 2 and Figure 3It can be seen that in the present application, the heat conversion component includes: a contact jacket 4, which is a semi-arc structure, the inner wall of the contact jacket 4 is provided with an electric contact network for heat conversion, and the outside of the contact jacket 4 is fixed with a wiring harness 5 for electrical connection with the electric contact network. In addition, a carrier frame 203 is fixed on one side of the outside of the carrying shell 201, and the base of the drive motor 202 is installed on the top of the carrier frame 203. It should be noted that one end of the rotating arm 204 is rotatably connected to the bottom end inside the carrying shell 201, and the other end of the rotating arm 204 is rotatably connected to the middle part of the outer surface of the force-bearing folding arm 205.

[0030] Next, this article will introduce the specific implementation of the utility model in detail.

[0031] First, in the embodiment, the gantry 1 is made of high-strength steel, which has good stability and wear resistance. The carrying shell 201 in the clamping assembly 2 is made of high-temperature resistant material, which can maintain stability in a high temperature environment. The toothed disc 208 and the extension arm 207 are made of alloy material, which has high strength and wear resistance.
