[0028] The air inlet bin 1 is provided with a scattering chamber 14 inside, and the scattering chamber 14 is connected to the air inlet bin 1 . A bottom cone cap 5 is provided on the bottom surface 17 of the scattering chamber, and a fixing flange 51 is provided at the bottom of the bottom cone cap 5, and the bottom cone cap 5 is fixed by the fixing flange 51 .

[0029] The bottom cone cap 5 is provided with a rotating frame 6 at its periphery. Figure 3 , 6 As shown, the rotating frame 6 is tapered and includes a plurality of support rings 61, and the plurality of support rings 61 are spaced apart from each other. In the present embodiment, three support rings 61 are provided, and a plurality of vertical connecting portions 62 are provided between the support rings 61.
