Description

Technical Field

[0001] This utility model relates to the field of metal metallurgy technology, specifically to a powder material homogenization device for metal metallurgy. Background Technology

[0002] Powder metallurgy is a processing method that produces metal powder and then uses processes such as forming and sintering to make products from the metal powder or a mixture of metal powder and non-metal powder. It can produce special materials that are difficult to produce using ordinary smelting methods, and can also manufacture various precision mechanical parts. It saves labor and materials. Compared with traditional material processing, powder metallurgy materials and processes can improve material utilization, improve material performance, and reduce costs. The metal powder needs to be homogenized during the powder metallurgy process.

[0003] A search of the China Patent Network revealed a patent document with publication number CN219482490 U, which discloses a powder material homogenizing device for metal metallurgy. This device can improve the mixing effect of materials by accelerating the integration of materials at various levels through back-and-forth shaking, thereby increasing the processing efficiency of the device. At the same time, it facilitates thorough cleaning of the interior, reduces the workload of workers, ensures the cleanliness of the device's interior, and is highly practical.

[0004] However, the stirring rod only generates a unidirectional centrifugal force on the metal powder, which eventually causes the metal powder mixture to rotate synchronously. The two are in a relatively static state, resulting in poor quality of metal powder mixing, which affects subsequent metallurgical work. Since the end of the fixed tube is connected to the shell, some metal powder will enter the fixed tube during the mixing process, which prevents the subsequent drain pipe from delivering cleaning water to the shell. Therefore, a powder material homogenizing device for metal metallurgy is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a powder material homogenizing device for metal metallurgy, so as to solve the technical problems of low homogenization quality of metal powder and easy clogging during cleaning mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a powder material homogenizing device for metal metallurgy, comprising an outer cylinder, wherein a stirring assembly for homogenizing metal powder is assembled inside the outer cylinder, and a drive motor for driving the stirring assembly to rotate is assembled at the bottom of the outer cylinder.

[0007] The stirring assembly includes a drive shaft that rotates longitudinally at the inner axis of the outer cylinder. A partition is fixedly sleeved on the outer wall of the drive shaft near the top. Three sets of inner hollow shafts extending to the top of the partition are provided on the outer side of the drive shaft. Three sets of outer hollow shafts extending to the top of the partition are provided on the outer side of the inner hollow shafts. Multiple sets of stirring strips are provided at equal intervals on the curved outer walls of the inner and outer hollow shafts. A transmission gear is mounted on the outer wall of each set of outer and inner hollow shafts above the partition. An inner toothed ring is fixedly connected to the transmission gear mounted on the outer wall of the inner hollow shaft at the top of the outer cylinder. An outer toothed ring is fixedly connected to the transmission gear mounted on the outer wall of the outer hollow shaft at the top of the outer cylinder.

[0008] As a preferred technical solution, the stirring strips provided on the outer walls of the two adjacent sets of outer and inner hollow shafts are staggered vertically, and the bottoms of the outer and inner hollow shafts are in a non-contact state.

[0009] As a preferred technical solution, the top of the outer cylinder is provided with a connecting pipe extending into the top of the drive shaft, and a transfer groove is reserved at the contact position between the top of the drive shaft and the connecting pipe. The tops of the outer hollow shaft and the inner hollow shaft are provided with connecting pipes that communicate with the transfer groove.

[0010] As a preferred technical solution, each set of stirring bars has multiple sets of liquid outlets on its outer wall. A plug is fitted inside each liquid outlet, and a positioning rod is fixed on the side of the plug near the liquid outlet. A blind hole is provided at the contact position between the liquid outlet and the positioning rod, and a return spring fixed to the end of the positioning rod is provided in the blind hole.

[0011] As a preferred technical solution, a discharge pipe is connected to the outer wall of the outer cylinder near the bottom, and a base frame is welded to the bottom corner of the outer cylinder.

[0012] As a preferred technical solution, a circular channel is reserved at the contact position between the partition and the outer hollow shaft and the inner hollow shaft, and the circular channel is connected to the outer hollow shaft and the inner hollow shaft by bearings.

[0013] As a preferred technical solution, the connecting pipe is rotatably connected to the top of the outer hollow shaft and the inner hollow shaft using a bearing.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses a stirring assembly to allow materials located on the inner wall and center of the outer cylinder to flow and alternate, thereby improving the quality of uniform mixing of metal powder and plasticizer. The hollow shaft and stirring frame allow external water to enter the outer cylinder and spray out in a ring to rinse the various corners inside, improving the cleaning quality of the outer cylinder and preventing blockage caused by materials entering during stirring.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A powder material homogenizing device for metal metallurgy, such as Figures 1 to 7 As shown, it includes an outer cylinder 100, an inner assembly of a stirring component 200 for homogenizing metal powder, and a drive motor 130 for driving the stirring component 200 to rotate at the bottom of the outer cylinder 100.

[0029] The stirring assembly 200 includes a drive shaft 280 longitudinally rotatably positioned at the inner axis of the outer cylinder 100. A partition 210 is fixedly sleeved on the outer wall of the drive shaft 280 near its top. Three sets of inner hollow shafts 230 extending through to the top of the partition 210 are provided on the outer side of the drive shaft 280. Three sets of outer hollow shafts 220 extending through to the top of the partition 210 are provided on the outer side of the inner hollow shafts 230. The curved outer walls of both the inner hollow shafts 230 and the outer hollow shafts 220 are... Multiple sets of stirring bars 290 are provided at equal intervals and connected. Each set of outer hollow shafts 220 and inner hollow shafts 230 is equipped with a transmission gear 270 on its outer wall and above the partition plate 210. An inner toothed ring 250 is fixed to the top of the inner cylinder 100 and meshes with the transmission gear 270 assembled on the outer wall of the inner hollow shaft 230. An outer toothed ring 240 is fixed to the top of the inner cylinder 100 and meshes with the transmission gear 270 assembled on the outer wall of the outer hollow shaft 220.

[0030] The top of the outer cylinder 100 is provided with a connecting pipe 120 extending into the top of the drive shaft 280. A transfer groove 281 is reserved at the contact position between the top of the drive shaft 280 and the connecting pipe 120. The tops of the outer hollow shaft 220 and the inner hollow shaft 230 are provided with a connecting pipe 260 that connects to the transfer groove 281. Each set of stirring bar frames 290 has multiple sets of liquid outlets 291 on its outer wall. A plug 292 is sleeved inside the liquid outlet 291. A positioning rod 293 is fixed on the side of the plug 292 near the liquid outlet 291. A blind hole is provided at the contact position between the liquid outlet 291 and the positioning rod 293. A return spring 294 fixed to the end of the positioning rod 293 is provided in the blind hole.

[0031] When metal powder and plasticizer (engine oil, rubber or paraffin, etc.) are put into the outer cylinder 100, the output end of the drive motor 130 drives the drive shaft 280 to rotate, and the partition 210 on the outer wall rotates accordingly, causing its transmission gear 270 to roll on the outer wall of the outer gear ring 240 and the inner wall of the inner gear ring 250. At this time, the inner hollow shaft 230 rotates along with the partition 210 and also rotates on its own axis. The outer hollow shaft 220 also rotates with the partition 210, and its rotation direction is opposite to that of the inner hollow shaft 230. This can transport the mixture of metal powder and plasticizer located at the center of the outer cylinder 100 towards the inner wall of the outer cylinder 100. With the revolution of the partition 210, the mixture adhering to the inner wall of the outer cylinder 100 can also be transported towards the center, making the metal powder and plasticizer more evenly mixed.

[0032] After the mixture inside the outer cylinder 100 is discharged, the external water pipe is connected to the connecting pipe 120, allowing the water source to enter the transfer tank 281. Finally, it is transported through the connecting pipe 260 to the interior of each inner hollow shaft 230 and outer hollow shaft 220, and the water enters the stirring frame 290. Due to the water pressure, the plug 292 extends outward, allowing the water to be discharged from the gap between the plug 292 and the outlet 291, causing the water to spray out in a ring. This can rinse the corners of multiple stirring frames 290. The rotation of the inner hollow shaft 230 and outer hollow shaft 220 also completes the rinsing of the interior of the outer cylinder 100, thus facilitating the next use of the device. The return spring 294 restores the extended plug 292 to prevent the mixture from entering the outlet 291 during stirring and causing blockage.

[0033] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 and Figure 5 The stirring bars 290 provided on the outer walls of the two adjacent sets of outer hollow shafts 220 and inner hollow shafts 230 are staggered vertically, and the bottoms of the outer hollow shafts 220 and inner hollow shafts 230 are in a non-contact state.

[0034] This prevents adjacent mixing bars 290 from colliding, allowing the mixture located at the center of the outer cylinder 100 to gradually flow towards the edge.

[0035] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer wall of the outer cylinder 100 is connected to a discharge pipe near the bottom, and a base frame 110 is welded to the bottom corner of the outer cylinder 100.

[0036] It provides stable support for the outer cylinder 100, preventing the drive motor 130 at the bottom from being subjected to external forces, and allowing the material inside the outer cylinder 100 to flow out through the discharge pipe after being evenly mixed.

[0037] Please refer to this carefully. Figure 2 and Figure 3 The partition 210 has a reserved circular channel at the contact position with the outer hollow shaft 220 and the inner hollow shaft 230, and the circular channel is connected to the outer hollow shaft 220 and the inner hollow shaft 230 by bearings.

[0038] The partition 210 isolates the uniform material, preventing it from contacting the gear ring and affecting the transmission effect between them. At the same time, the bearing reduces the wear between the partition 210 and the outer hollow shaft 220 and inner hollow shaft 230, thus extending its service life.

[0039] Please refer to this carefully. Figure 1The connecting pipe 260 is rotatably connected to the top of the outer hollow shaft 220 and the inner hollow shaft 230 by bearings.

[0040] The arrangement of the connecting pipe 260 ensures that it does not affect the rotation of the outer hollow shaft 220 and the inner hollow shaft 230, thus guaranteeing the stirring quality of the metal powder mixture.

[0041] Please refer to this carefully. Figure 1 The outer wall of the outer cylinder 100 is connected to a feed pipe near the top.

[0042] The metal powder and other materials to be homogenized are fed into the outer cylinder 100 through the feed pipe.

[0043] When metal powder and plasticizer (such as engine oil, rubber, or paraffin wax) are put into the outer cylinder 100, the output end of the drive motor 130 drives the drive shaft 280 to rotate, and the partition 210 on the outer wall rotates accordingly, causing its transmission gear 270 to roll on the outer wall of the outer gear ring 240 and the inner wall of the inner gear ring 250. At this time, the inner hollow shaft 230 rotates along with the partition 210 and also rotates on its own axis. The outer hollow shaft 220 also rotates with the partition 210, but its rotation direction is opposite to that of the inner hollow shaft 230. This can convey the mixture of metal powder and plasticizer located at the center of the outer cylinder 100 towards the inner wall of the outer cylinder 100. With the revolution of the partition 210, the mixture adhering to the inner wall of the outer cylinder 100 can also be conveyed towards the center, making the metal powder and plasticizer more evenly mixed.

[0044] After the mixture inside the outer cylinder 100 is discharged, the external water pipe is connected to the connecting pipe 120, allowing the water source to enter the transfer tank 281. Finally, it is transported through the connecting pipe 260 to the interior of each inner hollow shaft 230 and outer hollow shaft 220, and the water enters the stirring frame 290. Due to the water pressure, the plug column 292 extends outward, allowing the water to be discharged from the gap between the plug column 292 and the outlet 291, causing the water to spray out in a ring. This can rinse the corners of multiple stirring frames 290. The rotation of the inner hollow shaft 230 and outer hollow shaft 220 also completes the rinsing of the interior of the outer cylinder 100, thus facilitating the next use of the device. The return spring 294 restores the extended plug column 292 to prevent the mixture from entering the outlet 291 during stirring and causing blockage. The parts of the device not mentioned are the same as or can be implemented using existing technology.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, but such modifications, substitutions, and variations are protected by patent law as long as they fall within the scope of the claims of the present invention.
