[0006] The upper parts of two adjacent tube rings are fixedly connected through a plurality of arc plates, and the arc plates are fixedly connected through a connecting plate.

[0007] The disc body, the tube ring, the arc plate and the connecting plate are integrally formed.

[0008] The thickness of the tube ring and the arc plate is greater than the thickness of the disc body and the connecting plate.

[0009] The carbonization rotary kiln inner tube support flower disc provided by the utility model effectively fixes the tubes in the kiln, is connected with the inner wall of the kiln, reduces the influence of stress deformation, reduces the influence of heat conduction, and reduces heat energy loss.

[0014] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the embodiments in the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] As Figures 1-2 shown, the carbonization rotary kiln inner tube supporting flower disc of the present application comprises a disc body 1, the disc body 1 is a ring-shaped plate structure, a plurality of tube column rings 2 are uniformly fixed on the inner edge of the disc body 1, and a plurality of arc-shaped notches 3 are formed on the outer edge of the disc body 1.

[0016] The tube column ring 2 is a circular ring structure, and the bottom of the tube column ring 2 is embedded in the inner edge of the disc body 1.

[0017] The upper parts of two adjacent tube column rings 2 are fixedly connected through a plurality of arc plates 4, and the plurality of arc plates 4 are fixedly connected through a connecting plate 5.

[0018] The disc body 1, the tube column ring 2, the arc plate 4 and the connecting plate 5 are integrally formed.

[0019] The thicknesses of the tube column ring 2 and the arc plate 4 are greater than the thicknesses of the disc body 1 and the connecting plate 5.

[0020] The carbonization rotary kiln inner tube supporting flower disc provided by the present application can effectively fix the tube column in the kiln, and is connected with the inner wall of the kiln at points. The point connection here refers to a long linear complete connection different from the traditional circular ring. The connecting part has a gap, so that the stress deformation has a margin, thereby reducing the influence of stress deformation. At the same time, due to the reduction of the contact area, the influence of heat conduction can also be reduced, and the energy consumption can be reduced. Figure 1 As shown in the figure, it is only a structure example of the present application, and the size of the arc-shaped notch 3 is determined according to the actual situation in actual use, so as to determine the size of the point connection between the disc body 1 and the inner wall of the rotary kiln.
