The transmission shaft 5 is coaxially arranged with the conveying groove 10. A portion of the drive shaft 5 extends into the conveying trough 10 and the portion of the drive shaft 5 is provided with helical blades 9. The transmission shaft 5 extends into a venturi dryer 13 of the aluminum hydroxide roasting furnace. The discharge end of the screw conveying mechanism, namely one end of the transmission shaft 5 extending to the Venturi dryer 13 of the aluminum hydroxide roasting furnace, is connected with a bulk material stirring wheel 14, and the bulk material stirring wheel 14 is positioned in the Venturi dryer 13 of the aluminum hydroxide roasting furnace. In this embodiment, the bulk material pusher wheel 14 has an umbrella-like structure. Raw materials are uninterruptedly carried to the discharge end under screw conveyor's rotation promotion effort, and at the discharge end, bulk cargo thumb wheel rotates along with the transmission shaft, and the raw materials is dispersed through bulk cargo thumb wheel 14, has avoided the raw materials to pile up vertical dropping. Because the raw materials do not fall vertically, the action time of ascending air flow in the cone section of the Venturi dryer of the roasting furnace system is prolonged, the raw materials can be completely brought into an upper system, the phenomenon that the raw materials cannot be blown away by the ascending air flow after being piled, falling and agglomerating is avoided, the roasting furnace system is blocked after the raw materials fall into the bottom, and the problem of blanking is solved.
Embodiment 2 differs from embodiment 1 in that the bulk material deflector wheel 14 comprises a connecting member and a cone 14-5 arranged at intervals, as shown in fig. 2 and 3, the connecting member being used for connecting the bulk material deflector wheel 14 with the transmission shaft 5 connected with the screw conveyor. The cone 14-5 is arranged on the side of the connection piece remote from the drive shaft 5, and the small end of the cone 14-5 is directed towards the drive shaft 5. The cone 14-5 is connected to the connection piece by a number of long blades 14-3 arranged circumferentially. And the long blades 14-3 are connected to the outside of the cone 14-5.

And the short blades 14-4 are staggered with respect to the long blades 14-3. In this embodiment, 8 long blades 14-3 and 8 short blades 14-4 are provided. The 8 long lobes 14-3 and the 8 short lobes 14-4 are staggered in space, i.e., each short lobe 14-4 is disposed between two adjacent long lobes 14-3.
Embodiment 5 differs from embodiment 4 in that the connection member comprises a connection ring 14-2 coaxially arranged with the cone 14-5, and the connection ring 14-2 is coaxially arranged with the transmission shaft 5, as shown in fig. 2 and 4. One end of the connecting ring 14-2 close to the transmission shaft 5 is provided with a round connecting plate 14-1 for connecting the transmission shaft 5, and the connecting plate 14-1 is connected with the transmission shaft 5 through a connecting bolt 15. A plurality of long blades 14-3 are rotationally symmetrically disposed on the outer circumference of the connection ring 14-2. And the extension line of the long blade 14-3 is deviated from the axis of the connection ring 14-2, i.e. the arrangement of the long blade 14-3 outside the connection ring 14-2 is similar to the structure of a windmill blade. And the arrangement of the short blades 14-4 outside the cone 14-5 is also similar to the structure of a windmill blade.
