Description

Technical Field

[0001] This utility model relates to the field of vanadium-nitrogen alloy production technology, and in particular to an airflow conveying device for vanadium-nitrogen alloy production. Background Technology

[0002] The production of vanadium-nitrogen alloys involves multiple processes, including grinding, feeding, proportioning, mixing, pressing, and screening. The feeding process typically combines mechanical and manual methods. For a long time, due to equipment limitations, raw material feeding has relied on manual labor using overhead cranes. The cranes hoist materials to a 10-meter platform, and workers shuttle between the ground and the platform to feed the material at the feeding port. This method is labor-intensive, time-consuming, has low mechanization, and poses significant safety risks. Furthermore, the large amount of dust generated during feeding causes environmental pollution and material waste, seriously affecting the physical and mental health of workers. Traditional feeding methods using scrapers and bucket elevators are prone to leakage, leading to environmental pollution and material waste. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that lead to environmental pollution and waste of raw materials, and to propose an airflow conveying device for the production of vanadium-nitrogen alloys.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design an airflow conveying device for the production of vanadium-nitrogen alloys, including a conveying hopper, a conveying pipe connected to the lower end of the conveying hopper, a feeder on the conveying pipe, a third connecting pipe connected to the conveying pipe, a fan on the third connecting pipe, a second connecting pipe, a fifth connecting pipe and a seventh connecting pipe connected to the third connecting pipe, the second connecting pipe being connected to a first graphite hopper and a vanadium oxide hopper via a first connecting mechanism, the fifth connecting pipe being connected to a second graphite hopper and a fourth graphite hopper via a second connecting mechanism, and the seventh connecting pipe being connected to a grinding machine via a third connecting mechanism.

[0010] The present invention proposes an airflow conveying device for the production of vanadium-nitrogen alloys. The advantages are as follows: by placing different raw materials into the conveying bins and using a fan to convey the raw materials to different bins or grinding mills, the continuous sealed conveying avoids environmental pollution and waste of raw materials caused by material leakage. At the same time, it eliminates hoisting operations, reduces personnel on duty, and reduces the risk of materials falling from heights. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Refer to Figure 1A pneumatic conveying device for the production of vanadium-nitrogen alloys includes a conveying hopper 17. A conveying pipe 15 is connected to the lower end of the conveying hopper 17. A feeder 16 is installed on the conveying pipe 15. A third connecting pipe 6 is connected to the conveying pipe 15. A fan 18 is installed on the third connecting pipe 6. A second connecting pipe 5, a fifth connecting pipe 11, and a seventh connecting pipe 23 are connected to the third connecting pipe 6. The second connecting pipe 5 is connected to a first graphite hopper 2 and a vanadium oxide hopper 12 via a first connecting mechanism. The fifth connecting pipe 11 is connected to a second graphite hopper 13 and a fourth graphite hopper 14 via a second connecting mechanism. The seventh connecting pipe 23 is connected to a grinding machine 20 via a third connecting mechanism. By placing different raw materials into the conveying hopper 17 and using the fan 18 to convey the raw materials, the materials are transported to different hoppers or the grinding machine 20. Because continuous sealed conveying is used, environmental pollution and raw material waste caused by material leakage are avoided. Simultaneously, hoisting operations are eliminated, personnel on duty are reduced, and the risk of materials falling from heights is lowered.

A second valve 4 is provided at the upper end of the second connecting pipe 5, and the lower end of the second connecting pipe 5 is connected to a vanadium oxide silo 12. The lower end of the first pipe 1 is connected to a first graphite silo 2. When it is necessary to transport graphite into the first graphite silo 2, the third valve 8, the sixth valve 24, and the seventh valve 25 are closed, and the first valve 3 and the second valve 4 are opened to transport graphite from the conveying bin 17 into the first graphite silo 2.

[0016] The second connecting mechanism includes a fourth connecting pipe 7, which is connected to a fifth connecting pipe 11. A fifth valve 10 is installed on the fourth connecting pipe 7, and a fourth graphite hopper 14 is connected to the lower end of the fourth connecting pipe 7. A third valve 8 is installed at the upper end of the fifth connecting pipe 11, and a second graphite hopper 13 is connected to the lower end of the fifth connecting pipe 11. A fourth valve 9 is installed in the middle of the fifth connecting pipe 11. By controlling the valves, graphite of different specifications can be fed into different graphite hoppers.

[0017] The third connecting mechanism includes a seventh connecting pipe 23, on which two grinding machines 20 are connected and a seventh valve 25 is installed. The grinding machines are used to grind the conveyed vanadium oxide blocks. All valves are solenoid valves.
