[0021] like Figure 1-3 As shown, an aluminum powder adding device for aluminum powder smelting includes a guide cover 1, a heat-resistant tube 2, a guide plate 3, and a guide block 4. The guide cover 1 is a hollow structure, one end of the guide cover 1 is connected to the first end of the heat-resistant tube 2, and the other end of the guide cover 1 is open. A guide block 4 is fixedly arranged in the middle of the open opening of the guide cover 1, and the guide block 4 has a through straight outlet hole 5. An even number of guide plates 3 are arranged along the edge of the guide cover 1 and are evenly distributed on both sides of the guide block 4. At the same time, the guide plates 3 on both sides are arranged tilted, and the tilt directions are opposite. The second end of the heat-resistant tube 2 is connected to a powder feeding structure.

[0022] Specifically, the hollow structure of the air guide cover 1 can pass through the air flow and the aluminum powder carried by the air flow. The aluminum powder enters the air guide cover 1 from the heat-resistant tube 2, and is then guided by the guide plate 3 with the opposite tilt direction, and can diffuse at a large angle. At the same time, some aluminum powder can pass through the straight outlet hole 5 and diffuse forward.

[0023] Furthermore, the powder feeding structure includes a conveying pipe 6, a powder conveyor 7 and a ceramic tube 12. The output part of the powder conveyor 7 is connected to the ceramic tube 12 through the conveying pipe 6. The end of the ceramic tube 12 facing away from the conveying pipe 6 is connected to the second end of the heat-resistant tube 2. The heat-resistant tube 2, the conveying pipe 6 and the powder conveyor 7 are connected with a fastening component for fastening the three.

[0024] Specifically, the powder conveyor 7 is an existing technology and is not described in detail. The powder conveyor 7 can deliver aluminum powder into the air guide cover 1 through airflow. At the same time, in order to prevent high temperature from damaging the conveying pipe 6, the heat-resistant pipe 2 and the conveying pipe 6 are connected through the ceramic pipe 12, and the heat-resistant pipe 2, the ceramic pipe 12 and the conveying pipe 6 are fastened by a fastening assembly.

[0025] Furthermore, there are two groups of fastening assemblies, and the two groups of fastening assemblies are arranged opposite to each other. At the same time, the two groups of fastening assemblies are connected by fasteners. The end of the conveying pipe 6 facing away from the powder conveyor 7 is connected to the fastening assembly through the flange 8. The fastening assembly includes a mounting plate 9, a first hoop plate 10, a second hoop plate 11 and an assembly flange 14. The first hoop plate 10 and the second hoop plate 11 are arranged side by side, and the two ends of the mounting plate 9 are fixedly connected to the first hoop plate 10 and the second hoop plate 11 respectively, and one end of the second hoop plate 11 is fixedly connected to the assembly flange 14.

[0026] Specifically, the relatively arranged fastening components are assembled together by fasteners, and can clamp the heat-resistant tube 2 and the ceramic tube 12 through the first hoop plate 10 and the second hoop plate 11, and then the delivery pipe 6 is connected to the assembly flange 14 through the flange plate 8, so that the three are connected, and the ceramic tube 12 reduces the heat transfer.

[0027] Furthermore, a plurality of mounting holes 13 for fasteners to pass through are provided on the surface of the mounting plate 9. Fasteners such as bolts can pass through the mounting holes 13 to fasten the mounting plates 9 together and are detachable.

[0029] Furthermore, the air guide cover 1 is conical and its thickness is equal to the diameter of the heat-resistant tube 2. The cone shape can increase the diffusion angle of the aluminum powder, and the thickness is the same as the diameter of the heat-resistant tube 2, which can ensure that the aluminum powder output from the heat-resistant tube 2 enters the air guide cover 1 evenly and then diffuses.

[0030] In the above structure, the deflector 1 is installed in the boiler, and the heat-resistant tube 2 is passed through the boiler. The powder conveyor 7 is started to convey the aluminum powder. The aluminum powder enters the deflector 1 through the conveying pipe 6, the ceramic tube 12 and the heat-resistant tube 2 in sequence, and then diffuses to the surroundings under the guidance of the guide plate 3, so as to prevent the aluminum powder from entering the boiler unevenly and affecting the smelting effect.
