[0013] See Figures 1-2 A titanium dioxide conveying device, the outlet at the bottom of the storage tank 1 is connected to the gate valve 2 and the star-shaped discharger 3 in sequence, and is characterized in that: the bottom of the star-shaped discharger 3 is connected to the discharge pipe 4, the bottom of the discharge pipe 4 is connected to the upward inclined feed pipe 5 through a bend, and the feed pipe 5 enters the packaging process; the feed pipe 5 is connected to the negative pressure system, and the other side of the bend is also horizontally connected to the bypass pipe 6, and the bypass pipe 6 is tangentially connected to the air inlet pipe 7 in the horizontal direction.

[0014] The air inlet pipe 7 is provided with a control valve 8 , and a filter screen 9 is installed at the head end of the air inlet pipe 7 .

[0015] A spiral sampler 10 is provided in the discharge pipe 4 .

[0016] The end of the bypass pipe 6 is connected to a tapered inspection port 11, and the end face of the tapered inspection port 11 is closed by a flange and a blocking plate.

[0017] The control valve 8 is interlocked with the negative pressure system and controlled by a PLC control system.

[0018] Working principle: Fresh air passes through the filter 9 and enters the control valve 8 to the air inlet pipe 7, guiding the airflow to enter the bypass pipe 6 in a tangential direction, so that the airflow forms a vortex flow in the conveying pipe 5. The kinetic energy principle of airflow is used to flush the side wall of the pipe, so that the material is suspended and does not hang on the wall. The system wind quickly takes away the material, making the material transportation smoother and preventing material accumulation in the pipeline.
