[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0020] Example 1, according to Figure 1 , 2As shown, this embodiment proposes a powder feeding device, including a structural component 1 and a nozzle 2. One end of the nozzle 2 is installed inside the structural component 1, and a spray pipe 3 is installed at the output end of the nozzle 2. A feed pipe 4 is installed at the input end of the structural component 1, and a compressed air inlet 5 is provided at the lower end of the structural component 1.
[0021] The nozzle 2 has a guide pipe 6 at its inner end, and the guide pipe 6 is located inside the structural component 1. An annular high-pressure chamber 7 is formed between the outer side of the guide pipe 6 and the inner side of the structural component 1. The compressed air inlet 5 is connected to the annular high-pressure chamber 7. In use, a pneumatic conveying method is used to allow compressed air to flow into the annular high-pressure chamber 7 through the compressed air inlet 5 of the structural component 1 and then flow at high speed through the nozzle 2. This high-speed airflow creates a vacuum at the inlet of the structural component 1, causing the material connected to the feed pipe 4 to be sucked in by the high-speed airflow and transported to the target location through the nozzle 3. The entire process only requires the introduction and adjustment of the compressed air volume to achieve controllable speed material extraction. The structural component has a simple structure, requires no maintenance, and is highly efficient.
[0022] One end of the outer side of the nozzle 2 is provided with an embedded groove, and the inside of the embedded groove is filled with a sealing ring 9. The outer side of the nozzle 2 is sealed to the structural component 1 by the sealing ring 9. In use, the sealing ring 9 seals the outer side of the nozzle 2 and the structural component 1 to improve the sealing performance and prevent air leakage.
[0023] One end of the guide pipe 6 is an inclined guide head 10, and one end of the structure 1 is provided with a guide ring 11. The inclined guide head 10 and the guide ring 11 cooperate to guide the airflow in the annular high-pressure chamber 7 to the nozzle 3. In use, compressed air flows into the annular high-pressure chamber 7 through the compressed air inlet 5 of the structure 1, and then passes through the gap between the inclined guide head 10 and the guide ring 11 of the guide pipe 6. It is guided to flow at high speed to the output end of the nozzle 2. This high-speed airflow creates a vacuum at the inlet of the structure 1, so that the material connected to the feed pipe 4 is sucked in by the high-speed airflow and transported to the target location through the nozzle 3.
[0024] The diameter of the nozzle 2 gradually increases from one end of the guide tube 6 to the output end, while the diameter of the nozzle 3 gradually decreases from one end of the inlet to the output end. This gradual change in diameter allows airflow to pass through at high speed, thereby carrying and conveying materials.
[0025] Example 2, according to Figure 1 , 2 As shown, this embodiment proposes a powder feeding device, including a structural component 1 and a nozzle 2. One end of the nozzle 2 is installed inside the structural component 1, and a spray pipe 3 is installed at the output end of the nozzle 2. A feed pipe 4 is installed at the input end of the structural component 1, and a compressed air inlet 5 is provided at the lower end of the structural component 1.
[0026] The nozzle 2 has a guide pipe 6 at its inner end, and the guide pipe 6 is located inside the structural component 1. An annular high-pressure chamber 7 is formed between the outer side of the guide pipe 6 and the inner side of the structural component 1. The compressed air inlet 5 is connected to the annular high-pressure chamber 7. In use, a pneumatic conveying method is used to allow compressed air to flow into the annular high-pressure chamber 7 through the compressed air inlet 5 of the structural component 1 and then flow at high speed through the nozzle 2. This high-speed airflow creates a vacuum at the inlet of the structural component 1, causing the material connected to the feed pipe 4 to be sucked in by the high-speed airflow and transported to the target location through the nozzle 3. The entire process only requires the introduction and adjustment of the compressed air volume to achieve controllable speed material extraction. The structural component has a simple structure, requires no maintenance, and is highly efficient.
[0027] The nozzle 2 has a thread 8 on its outer side, and is installed to the structural component 1 via the thread 8. The compressed air inlet 5 has an internal thread on its inner side, and a connector 12 is installed to the compressed air inlet 5 via the internal thread. An air pipe 13 is connected to the connector 12. An installation head is connected to the input end of the structural component 1. The feed pipe 4 is sleeved on the installation head, and a clamp 14 is provided on the outer side of the feed pipe 4. The feed pipe 4 and the installation head are fixed together by the clamp 14. In use, the structural component 1 and the nozzle 2 are fixed together by the thread 8, the feed pipe 4 and the installation head of the structural component 1 are fixed together by the clamp 14, and the connector 12 and the compressed air inlet 5 are fixed together by the internal thread, making installation and disassembly convenient.
[0028] The diameter of the nozzle 2 gradually increases from one end of the guide tube 6 to the output end, while the diameter of the nozzle 3 gradually decreases from one end of the inlet to the output end. This gradual change in diameter allows airflow to pass through at high speed, thereby carrying and conveying materials.
[0029] This powder extraction device uses pneumatic conveying. Compressed air flows into the annular high-pressure chamber 7 through the compressed air inlet 5 of structural component 1 and then flows at high speed through the nozzle 2. This high-speed airflow creates a vacuum at the inlet of structural component 1, causing the material connected to the feed pipe 4 to be sucked in by the high-speed airflow and transported to the target location through the nozzle 3. The entire process only requires the introduction and adjustment of the compressed air volume to achieve controllable speed extraction. The structural component is simple, requires no maintenance, and is highly efficient. Furthermore, structural component 1 and nozzle 2 are fixed with threads 8, feed pipe 4 and mounting head of structural component 1 are fixed with clamps 14, and connector 12 and compressed air inlet 5 are fixed with internal threads, making installation and disassembly convenient.
