[0024] Example 1: Please refer to Figures 1 to 5The present invention relates to a powder material mixing device 100, comprising a mixing tank 10 and a mixing assembly 20. The mixing tank 10 includes a tank body 11, an inlet pipe 12 and an outlet pipe 13, the inlet pipe 12 and the outlet pipe 13 being connected to the two ends of the tank body 11 respectively. The mixing assembly 20 includes an air pipe 21, a coil 22 and a plurality of air nozzles 23. The air pipe 21 passes through the tank body 11, one end of the air pipe 21 is connected to the coil 22 and the other end is connected to an air pump. The coil 22 is installed inside the tank body 11. The air nozzles 23 are rotatably connected to the coil 22 to adjust the direction of air jet from the air nozzles 23. The air nozzles 23 are connected to the coil 22 and are arranged circumferentially along the coil 22. The powder mixing device 100 of this embodiment feeds various powder materials into the tank 11, blows air through the air pipe 21 toward the coil 22, and then sprays air through multiple air nozzles 23 toward the tank 11. The airflow makes the powder materials in the tank 11 flow fully, thereby fully mixing the powder materials. The direction of the air spray is adjusted by rotating the air nozzles 23 to the coil 22. It has a wide range of applications.

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the mixing tank 10 includes a tank body 11, an inlet pipe 12, and an outlet pipe 13. The inlet pipe 12 and the outlet pipe 13 are respectively connected to both ends of the tank body 11. Optionally, the tank body 11 includes a cover portion 111, a discharge portion 112, an aggregating portion 113, and multiple support portions 114. The cover portion 111 covers one end of the discharge portion 112. The inlet pipe 12 is connected to the cover portion 111. One end of the aggregating portion 113 is connected to the discharge portion 112, and the other end is connected to the outlet pipe 13. Further, the cross-section of the aggregating portion 113 is an isosceles trapezoid. The length of the end of the aggregating portion 113 connected to the discharge portion 112 is greater than the length of the end of the aggregating portion 113 connected to the outlet pipe 13. The support portions 114 are installed on the inner side of the aggregating portion 113, and each support portion 114 is arranged circumferentially along the aggregating portion 113. In one embodiment, multiple support portions 114 are installed axially on the aggregating portion 113. The mixing tank 10 also includes a plurality of legs 14, one end of which is mounted on the outside of the tank body 11, and each leg 14 is arranged along the periphery of the tank body 11.

[0026] like Figures 1 to 5As shown, the mixing assembly 20 includes an air pipe 21, a coil 22, and multiple air nozzles 23. The air pipe 21 passes through the tank body 11, with one end connected to the coil 22 and the other end connected to an air pump. The coil 22 is installed inside the tank body 11. The air nozzles 23 are rotatably connected to the coil 22 to adjust the direction of air jets from the air nozzles 23. The air nozzles 23 are connected to the coil 22, and each air nozzle 23 is arranged circumferentially along the coil 22. Optionally, the coil 22 is circular. Further, the air pipe 21 passes through a gathering part 113, the coil 22 is installed in the gathering part 113, and a support part 114 is used to support the coil 22. The air nozzle 23 is provided with an inclined hole 231. One end of the inclined hole 231 extends outward from the central axis of the air nozzle 23, that is, the air outlet end of the inclined hole 231 is eccentrically set. By adjusting the position of the air nozzle 23, the position of the air outlet end of the inclined hole 231 is adjusted, and the air outlet angle is changed to adapt to different powder materials. Optionally, since the coil 22 is circular, when the inclined hole 231 of each air nozzle 23 is tangent to the coil 22, the airflow will form a vortex, and the powder material will float with the airflow, so that the powder material is fully mixed.

[0027] In one embodiment, the coil 22 includes a tube body 221 and multiple fixing parts 222 communicating with the tube body 221. Each fixing part 222 is arranged circumferentially along the tube body 221. Each fixing part 222 corresponds to a nozzle 23, and the nozzle 23 is detachably installed on the fixing part 222, communicating with the fixing part 222. Optionally, fixing parts 222 are installed at both the top and bottom of the tube body 221. Further, the two fixing parts 222 are arranged in a straight line. In one embodiment, there are multiple air pipes 21 and coils 22, each corresponding to the other. Each coil 22 is staggered along the axial direction of the tank 11 to ensure that the nozzles 23 spray airflow towards different areas, thus fully mixing the powder material. Optionally, each coil 22 is arranged along the axial direction of the gathering part 113, and the diameter of each coil 22 decreases sequentially. Further, the nozzles 23 on adjacent coils 22 are staggered, allowing the nozzles 23 to spray airflow towards different areas, improving gas utilization.

[0028] like Figure 3 and Figure 5 As shown, the mixing assembly 20 also includes a sealing gasket 24 and a cover plate 25. The sealing gasket 24 is installed on the fixing part 222, and one end of the air nozzle 23 abuts against the sealing gasket 24. The sealing gasket 24 connects the fixing part 222 and the air nozzle 23. The cover plate 25 covers the coil 22 and the air nozzle 23 to fix the air nozzle 23. Optionally, there are multiple sealing gaskets 24 and cover plates 25, and the sealing gaskets 24, cover plates 25 and air nozzles 23 are arranged one-to-one. In use, the angle between the oblique holes 231 of each air nozzle 23 on the coil 22 and the coil 22 is adjusted to be consistent. Then, the cover plate 25 is placed on the fixing part 222 and the air nozzle 23. Finally, the cover plate 25 and the fixing part 222 are fixed with screws to prevent the air nozzle 23 from rotating.

[0029] The powder material mixing device 100 also includes a conveyor 30, a sealing plate (not shown) and a control valve (not shown). The conveyor 30 is installed on the feed pipe 12, and the sealing plate is slidably disposed at one end of the discharge pipe 13. The sealing plate is used to close the discharge pipe 13. The control valve is used to drive the sealing plate to slide. Optionally, the conveyor 30 is prior art, and the sealing plate and control valve are both prior art.

[0030] In use, the discharge pipe 13 is closed, and various powder materials are conveyed into the tank 11 by the conveyor 30 until the preset material level is reached, at which point the conveyor 30 stops working. Next, air is blown from each air pipe 21 into the corresponding coil 22, and then air is sprayed into the tank 11 through each air nozzle 23. The airflow causes the powder materials in the tank 11 to flow fully. Because the coils 22 are staggered along the axial direction of the tank 11, the air nozzles 23 spray airflow into different areas, thereby fully mixing the powder materials, ensuring uniform mixing, and improving gas utilization and mixing efficiency.

[0031] Example 2: Please see Figure 6 This is a second embodiment of the powder material mixing device 100a of the present invention. This embodiment is similar to the powder material mixing device 100 of the first embodiment, except that the coil 22a of this embodiment is provided with a plurality of air holes 221a, each air hole 221a being arranged circumferentially along the coil 22a; optionally, the air holes 221a are located at the top of the coil 22a; further, the bottom of the coil 22a is also provided with a plurality of through holes 222a, each corresponding to one of the air holes 221a; in one embodiment, the through holes 222a and the air holes 221a are arranged at an angle. The through holes 222a of adjacent coils 22a are staggered, and the air holes 221a of adjacent coils 22a are also staggered. In other embodiments, the through holes 222a and the air holes 221a are straight holes, and the through holes 222a and the air holes 221a are located on the same straight line; the air holes 221a of adjacent coils 22a are staggered.

[0032] The powder material mixing device 100 of this utility model introduces various powder materials into a tank 11, blows air through an air pipe 21 toward a coil 22, and then sprays air through multiple air nozzles 23 toward the tank 11. The airflow makes the powder materials in the tank 11 flow fully, thereby fully mixing the powder materials. The direction of the air spray is adjusted by rotating the air nozzles 23 to the coil 22. It has a wide range of applications.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
