Description

Technical Field

[0001] This utility model relates to the technical field of aluminum powder production equipment, and in particular to a multi-stage dispersion device for aluminum powder production. Background Technology

[0002] Aluminum powder is a common industrial metal powder widely used in military, aerospace, chemical, metallurgical, and building materials industries. Existing aluminum powder preparation processes produce aluminum powder with a wide particle size distribution and significant differences in the size of fine aluminum particles, requiring further dispersion before it can be used as a raw material. Most existing multi-stage dispersion equipment uses vibration to disperse aluminum powder in multiple stages. The high vibration intensity can easily damage the aluminum powder, causing oxidation reactions and affecting the production quality. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage dispersion device for aluminum powder production, which solves the problem in the prior art where the aluminum powder dispersion intensity is too high, easily causing damage to the aluminum powder and thus affecting production quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a multi-stage dispersion device for aluminum powder production, comprising multiple layers of rollers, wherein a first roller, a second roller, and a third roller are arranged sequentially from the inside to the outside. The first and second rollers are provided with sieve holes, the size of which is larger than that of the second roller. A rotating shaft is located at the center of the first roller, and several connecting rods are arranged around the outer periphery of the rotating shaft. The ends of the connecting rods are fixedly connected to the inner wall of the first roller. Several connecting plates are evenly arranged between the first and second rollers, and several connecting rods are evenly arranged between the second and third rollers. The multi-layer roller has a dry connecting plate; support frames are provided at the inlet and outlet ends of the roller, and support seats are fixedly connected to the support frames. The two ends of the rotating shaft are rotatably connected to the two support seats respectively. A mounting frame is provided on one side of the support frame at the inlet end of the multi-layer roller, and a drive motor is provided on the mounting frame. The output end of the drive motor is connected to the rotating shaft for transmission. The outlet end of the multi-layer roller is provided with a first feeding plate, a second feeding plate, a first receiving box, a second receiving box, and a third receiving box in sequence. The first feeding plate matches the first receiving box, the second feeding plate matches the second receiving box, and the third receiving box is located below the third roller.

[0005] Optionally, the inner diameters of the first, second, and third rollers are arranged in a gradually expanding structure from the inlet end to the outlet end.

[0006] Optionally, a fixing frame is also provided on the top of the support frame near the inlet end of the multi-layer roller, and a feeding plate is inclined on the top of the fixing frame, with the bottom of the feeding plate extending into the interior of the first roller.

[0007] Optionally, several support devices are evenly provided at the bottom of the third roller.

[0008] Optionally, the support device includes a support platform that matches the third roller, and a plurality of support rollers are rotatably connected to the support platform, the support rollers being in contact with the outer surface of the third roller.

[0009] The multi-stage dispersion device for aluminum powder production of this invention has the following advantages:

[0010] (1) Aluminum powder is placed in the first drum. Under the drive of the drive motor, the three drums rotate synchronously. The aluminum powder with smaller particle size falls through the screen of the first drum into the second drum, and the aluminum powder with even smaller particle size falls through the screen of the second drum into the third drum, thereby realizing the multi-stage dispersion of aluminum powder. The rotation of the drum is slow and gentle, which will not damage the aluminum powder and ensure the production quality of aluminum powder.

[0011] (2) The gradual change in the inner diameter of the drum facilitates the discharge of aluminum powder.

[0012] (3) The support device can assist the support base in supporting the multi-layer rollers, making the overall operation of the device more stable. Attached Figure Description

[0015] Figure 3 This is a structural diagram of a multi-layered drum and support device. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, in which the following description will use the accompanying drawings as references. Figure 1 With the direction in the middle as the reference, the right end is the inlet end of the multi-layer roller 1, and the left end is the outlet end of the multi-layer roller 1.

[0017] like Figures 1-3 As shown, a multi-stage dispersion device for aluminum powder production includes a multi-layer drum 1. The multi-layer drum 1 is arranged sequentially from the inside to the outside as a first drum 2, a second drum 3, and a third drum 4. The first drum 2 and the second drum 3 are provided with sieve holes. The size of the sieve holes of the first drum 2 is larger than that of the sieve holes of the second drum 3. The inner diameters of the first drum 2, the second drum 3, and the third drum 4 are arranged in a gradually expanding structure from the inlet end to the outlet end to facilitate the discharge of aluminum powder.

[0018] A rotating shaft 5 is centrally located on the first roller 2. Several connecting rods 6 are arranged around the outer periphery of the rotating shaft 5. The ends of the connecting rods 6 are fixedly connected to the inner wall of the first roller 2, providing fixed support. Several connecting plates 7 are evenly arranged between the first roller 2 and the second roller 3, and between the second roller 3 and the third roller 4. The connecting plates 7 provide fixed support for the second roller 3 and the third roller 4. Several supporting devices are evenly arranged at the bottom of the third roller 4, symmetrically positioned on both sides of the third roller 4. Each supporting device includes a supporting platform that matches the third roller 4. Several supporting rollers are rotatably connected to the supporting platform, and the supporting rollers are in contact with the outer surface of the third roller 4, providing support for the multi-layer roller 1.

[0019] The multi-layer roller 1 has support frames 8 at its inlet and outlet ends, with support seats 9 fixedly connected to the support frames 8. The two ends of the rotating shaft 5 are rotatably connected to the two support seats 9, and the support seats 9 cooperate with the support device to ensure the stability of the multi-layer roller 1. A mounting frame 10 is provided on one side of the support frame 8 at the inlet end of the multi-layer roller 1. A drive motor 11 is mounted on the mounting frame 10, and the output end of the drive motor 11 is connected to the rotating shaft 5. The drive motor 11 drives the rotating shaft 5 to rotate, thereby causing the three rollers to rotate synchronously.

[0020] A fixing frame 12 is also provided on the top of the support frame 8 at the right end. A feeding plate 13 is inclinedly provided on the top of the fixing frame 12. The bottom of the feeding plate 13 extends downward into the interior of the first roller 2. Aluminum powder falls onto the feeding plate 13 and then slides into the first roller 2, which facilitates the feeding of aluminum powder. The outlet end of the multi-layer roller 1 is provided with a first receiving box 14, a second receiving box 15, and a third receiving box 16 in sequence. An arc-shaped first discharge plate 17 is provided between the outlet of the first roller 2 and the first receiving box 14. The aluminum powder with the largest particle size falls into the first receiving box 14 through the first discharge plate 17. An arc-shaped second discharge plate 18 is provided between the outlet of the second roller 3 and the second receiving box 15. The aluminum powder with a slightly smaller particle size falls into the second receiving box 15 through the second discharge plate 18. The third receiving box 16 is located below the outlet of the third roller 4. The aluminum powder with the smallest particle size falls directly into the third receiving box 16.

[0021] Driven by the drive motor 11, the three rollers rotate synchronously. Aluminum powder enters the first roller 2 through the feeding plate 13. Smaller aluminum powder particles pass through the screen of the first roller 2 and fall into the second roller 3, while even smaller aluminum powder particles pass through the screen of the second roller 3 and fall into the third roller 4. The three particle sizes of aluminum powder finally fall into the three receiving boxes respectively, thus achieving multi-stage dispersion of aluminum powder. The rotation of the multi-layer roller 1 is slow and gentle, ensuring a stable screening process without damaging the aluminum powder and guaranteeing the production quality of the aluminum powder.
