The base 2 and the mounting frame 4 are provided to support the reaction tank 1, and the first conveyor belt 40 is used to send the material discharged from the discharge port out from under the reaction tank 1.
[0027] As a preferred embodiment of the present invention, the reaction tank 1 is provided with a discharge port below the reaction zone 11, and two flip plates 90 are symmetrically mounted at the discharge port to achieve rapid discharge of the reacted material, avoid accumulation and blockage of the material in the reactor, and improve production efficiency.

[0033] When the continuous fluidized bed reactor for purifying high titanium slag of the utility model is used, first, the raw materials are added layer by layer to the second conveyor belt 5 through a plurality of equally spaced weighing funnels 3 on the top of the reaction tank 1. Each weighing funnel 3 is equipped with a solenoid valve 30, and by controlling the opening and closing timing of the solenoid valve 30, it can be ensured that the raw materials can be laid layer by layer on the second conveyor belt 5. Specifically, the time interval between the opening of two adjacent solenoid valves 30 is equal to the time for the second conveyor belt 5 to transport the material through the two adjacent weighing funnels 3, so that the uniform distribution of the raw materials can be achieved.
[0034] As the second conveyor belt 5 runs, the raw materials are gradually transported to the reaction zone 11. In the reaction zone 11, a stirring component is provided. The stirring motor 81 drives the stirring shaft 8 to rotate, thereby driving the stirring blades 80 to force stirring and mixing the raw materials, thereby improving the reaction efficiency and product quality. After the reaction is completed, the material is discharged through the discharge port at the bottom of the reaction tank 1. When discharge is required, the flip motor 9 drives the flip plate 90 to open, and the material is discharged smoothly. After the discharge is completed, the flip motor 9 drives the flip plate 90 to close to prevent external impurities from entering the interior of the reaction tank 1.
