Description

Technical Field

[0001] This utility model relates to the technical field of aluminum powder production equipment, specifically to a dual-nozzle atomizing aluminum powder production device. Background Technology

[0002] To increase production capacity and overcome the limitations of single-nozzle atomized aluminum powder production equipment, dual-nozzle atomized aluminum powder production equipment has emerged.

[0003] For example, CN 115026295 A discloses a dual-nozzle atomizing device for producing aluminum powder for construction. It includes a manufacturing cylinder with a support block fixedly installed at its lower end. Atomizing nozzles are symmetrically installed inside the manufacturing cylinder. A column groove and a feeding groove are formed at the lower end of the manufacturing cylinder, with the column groove located in the middle and the feeding groove on one side. A limit groove is formed in the inner wall of the column groove. A drive motor is fixedly installed at the upper end of a U-shaped plate. A rotating rod is fixedly installed at the output end of the drive motor. A first fan blade is fixedly installed on the side wall of the rotating rod. A slot is formed on the side wall of the first fan blade. A spring is fixedly installed in the inner wall of the slot. A second fan blade is fixedly installed on the side wall of the spring. A rectangular groove is formed on the side wall of the second fan blade. An inner column is rotatably installed in the inner wall of the rectangular groove. This device has the following problems: As is well known, aerosolized materials rise naturally, especially when supported by airflow. Therefore, the first and second fan blades on the rotating rod cause the aerosolized material to rise rapidly, but this is not conducive to the rapid deposition of the powder. Utility Model Content

On the one hand, it reduces the particle size of the powder, and on the other hand, it accelerates the settling speed of the aluminum powder, which is beneficial to the collection of aluminum powder.

[0005] The technical solution of this utility model is:

[0006] A dual-nozzle atomized aluminum powder production device includes an atomizing tank, two atomizing nozzles symmetrically arranged on both sides of the upper part of the atomizing tank, and a motor located at the top of the atomizing tank. The key technical features are: the upper part of the atomizing tank contains an upper conical disc, wider at the top and narrower at the bottom, connected to the output end of the motor. The surface of the upper conical disc has an upper through-hole group and multiple blades. Each blade is evenly arranged around the center line of the upper conical disc, and the length direction of the blades is along the generatrix direction of the upper conical disc.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the dual-nozzle atomized aluminum powder production device includes an atomizing tank 2, two atomizing nozzles 6 symmetrically arranged on both sides of the upper part of the atomizing tank 2, and a motor 1 located at the top of the atomizing tank 2. The top of the atomizing tank 2 is also provided with a material sorting outlet 23.

[0020] The atomizing canister 2 has an upper conical disc 4, wider at the top and narrower at the bottom, connected to the output end of the motor 1. The surface of the upper conical disc 4 has an upper through-hole group 22 and multiple blades 5, all evenly arranged around the center line of the upper conical disc 4, with the length direction of the blades 5 aligning with the generatrix of the upper conical disc 4. In this embodiment, the blades 5 are rectangular and have drag-reducing holes 21. The nozzle 6 faces the side center of the upper conical disc 4. The inner surface of the upper conical disc 4 has multiple connecting posts, the upper ends of which are connected to a common column 3. The upper end of the column 3 is fixedly connected to the output end of the motor 1. An annular air passage gap is formed between the upper edge of the upper conical disc 4 and the inner wall of the atomizing canister 2.

[0021] The lower end of the upper conical disc 4 is provided with a riser 17 communicating with it. The lower part of the riser 17 is provided with multiple connecting ribs 20, the lower ends of which are connected to the lower conical disc 11, which is wider at the top and narrower at the bottom. The bottom of the atomizing tank 2 is provided with a collecting cylinder 15. The upper end of the collecting cylinder 15 is provided with a wear-resistant sleeve 18 that connects to the lower end of the lower conical disc 11. The lower end of the riser 17 is inserted into the upper part of the collecting cylinder 15. Two vibration motors 14 are symmetrically fixed to the lower surface of the lower conical disc 11. In this embodiment, the lower end of the collecting cylinder 15 is provided with a slide valve 16. The lower inner wall of the atomizing tank 2 is provided with an annular support plate 10, and the upper outer wall of the lower conical disc 11 is provided with a support ring 9. A ball bearing support structure 19 is provided between the support ring 9 and the annular support plate 10. The lower end of the atomizing canister 2 is fixed with a detachable base plate 13, which is connected and fixed to the outer wall of the collecting cylinder 15. The lower outer wall of the atomizing canister 2 is connected and fixed to the bracket 12.

[0022] The side wall of the atomizing can 2 is provided with a sandwich layer 8, and a heating component 7 is provided in the sandwich layer 8.

[0023] Working principle:

[0024] During operation, the temperature inside the atomizing tank 2 is increased in advance using the heating component 7 to reach the set drying temperature range.

[0025] Then, the motor 1 is started, driving the upper conical disc 4 and the lower conical disc 11 to rotate synchronously. Then, the two atomizing nozzles 6 simultaneously spray atomized material into the atomizing tank 2. The powder particles are broken down into smaller particles by the rotating impact of each blade 5, reducing the particle size to meet customer requirements. At the same time, with the synergistic effect of the heating component 7, drying is accelerated. The powder particles sink faster under the resistance of the upper conical disc 4, fall onto the lower conical disc 11, and slide into the collection cylinder 15 under vibration. The powder that enters the upper conical disc 4 and then settles into granules is transported to the collection cylinder 15 through the riser 17 under vibration, thus achieving collection.

[0026] To further achieve separation, the lightweight material is conveyed to the grading mechanism through the separation material outlet 23 by the airflow.
