[0025] The specific operation is as follows: This application installs a high-temperature resistant corrugated pipe 11 on the gasification pipeline 9. When the weight measuring module 3 is displaced in the vertical direction, the corrugated pipe 11 in the gasification pipeline 9 connected to the sublimation furnace 1 and the gasification furnace can ensure that the pipeline has sufficient displacement to prevent leakage in the sealing equipment and facilitate process connection.
[0026] like Figure 3 As shown, a stirring motor 12 is bolted to the middle of the top of the vessel lid 7, and a stirring rod 13 is fixedly connected to the output end of the stirring motor 12.

[0027] The specific operation is as follows: On the one hand, this application adds a stirring rod 13 controlled by a stirring motor 12 to the middle of the kettle cover 7, which can stir at a uniform speed during the gasification of zirconium tetrachloride, effectively promoting the uniform release of gas and helping the gasification process to proceed smoothly.

[0028] Working Principle: When using this production device for precisely controlling the feeding rate of the sponge zirconium reduction reaction, the rate control module 4 is connected to the weight measurement module 3 and the temperature control thermocouple 5 of the sublimation furnace 1. The sublimation furnace 1 is placed on the weight measurement module 3. The sublimation furnace 1 mainly consists of the temperature control thermocouple 5, the heating element 2, the material container 6, the feeding assembly 15, and the gasification pipeline 9. The rate control module 4 can monitor the weight change ΔG of the sublimation furnace 1 in real time. When the weight change ΔG of the sublimation furnace 1 exceeds a certain range of the set value within a fixed time Δt, the rate control module 4 transmits the change signal to the temperature control thermocouple 5 and the heating element 2. The heating element 2 adjusts the heating power in time to change the volatilization rate of solid zirconium tetrachloride and further matches the weight change ΔG of the sublimation furnace 1 within a fixed time Δt, ultimately stabilizing the volatilization rate within a small range of the set value. After the zirconium tetrachloride has volatilized stably, it is introduced into the reduction reactor through the gasification pipeline 9 to undergo a reduction reaction with liquid magnesium. Ultimately, stable control of the feed rate was achieved. This application plays a fundamental role in the overall process innovation by arbitrarily adjusting the feeding speed during the reduction process.
