When in use, the constriction 2 is first connected to the decomposition furnace, and the connecting port 3 is connected to the rotary kiln. When the material is fed into the kiln, the material is put in from the feed port 4, and then the material falls along the discharge chute 51, which can effectively avoid the accumulation of material at the corner between the smoke chamber shell 1 and the connecting port 3, and avoid the increase of ventilation resistance in the kiln and affecting the calcination capacity of the kiln.
[0028] like Figure 2-3 As shown, the lower end of the discharge chute 51 is connected to a distribution piece 6, and a groove 61 is provided at one end of the distribution piece 6 away from the discharge chute 51. The bottom arc side of the distribution piece 6 is arranged close to the lower inner wall of the connecting port 3. Through the arrangement of the distribution piece 6, the material can be discharged in a scattered manner along the inner wall of the connecting port 3 after passing through the distribution piece 6 from the discharge chute 51, which can reduce the ventilation resistance in the kiln and improve the calcination capacity of the kiln.
[0029] like Figure 3 As shown, a plurality of guide plates 7 are fixedly disposed in the material distributing member 6.

[0033] like Figure 1As shown, the sealing cover 9 is threadedly connected to the crust cleaning port 8, and a handle 92 is symmetrically fixed on the sealing cover 9. The handle 92 is used to facilitate the rotation of the sealing cover 9 to separate the sealing cover 9 from the crust cleaning port 8. In this embodiment, an internal thread is provided on the inner side of the sealing cover 9, and an external thread is provided on the outer side of the crust cleaning port 8, and the internal thread is adapted to the external thread.
[0034] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
