Description

Technical Field

[0001] This utility model relates to the field of batching and mixing technology, and in particular to a batching and mixing device for preventing metal powder agglomeration. Background Technology

[0002] Metal powder, as an important industrial raw material, has a wide range of applications in many fields such as powder metallurgy, electronics, chemicals, and aerospace. For example, in the powder metallurgy industry, various high-precision and high-performance parts can be manufactured by pressing and sintering metal powder. In the electronics field, metal powder is used to manufacture conductive pastes and electronic packaging materials.

[0003] To alter the physical properties of metal powder (such as flowability and filling properties), it is necessary to prepare and stir the metal powder before use. However, during stirring, moisture from the environment can be adsorbed onto the surface of the metal powder, thereby increasing the adhesion between metal powder particles and causing the metal powder to agglomerate. This affects the normal use of the metal powder and also reduces the stirring quality of the metal powder after preparation. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a batching and mixing device that prevents metal powder agglomeration.

[0005] This utility model provides a batching and mixing device for preventing metal powder agglomeration, including a mixer body and a drive shaft. The drive shaft is fixedly connected to the inside of the mixer body. Multiple casters are symmetrically fixedly connected to the bottom of the mixer body. A mixing tank body is fixedly connected inside the mixer body and is located below the drive shaft.

[0006] An anti-agglomeration component is provided at the bottom of the drive shaft, and part of the outer surface of the anti-agglomeration component is located inside the mixing tank body.

[0007] Furthermore, the anti-agglomeration component includes a stirring shaft fixedly connected to the bottom end of the drive shaft, the outer surface of the stirring shaft is provided with a drainage port, the outer surface of the stirring shaft is provided with a dehumidification component and a shielding component, and the shielding component is provided at the top of the stirring tank body.

[0008] Furthermore, the stirring shaft has an inlet cavity inside, a stirring plate is fixedly connected to the outer surface of the stirring shaft, a heating cavity is inside the stirring plate, and an inlet is provided on the outer surface of the stirring shaft. The inlet communicates with the inlet cavity and the heating cavity.

[0009] Furthermore, multiple crushing columns are fixedly connected at equal angles to the outer periphery of the stirring shaft. The crushing columns are located below the stirring plate, and multiple crushing blocks are fixedly connected to the outer surface of the crushing columns. The crushing blocks are arranged in an alternating manner on the outer surface of the crushing columns.

[0010] Furthermore, the shielding assembly includes a shielding plate and a mounting plate disposed at the top of the mixing tank body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, when stirring metal powder, prevents metal powder from splashing into the air through the splicing of the baffle plate and the mounting plate, reducing the pollution of the stirring environment by metal powder. Heat is introduced into the guiding ring's drainage chamber through the inlet pipe, and then into the heating chamber within the stirring plate through the drainage hole, drainage port, and inlet chamber within the stirring shaft. This heat heats the outer surface of the stirring plate, allowing the stirring plate to simultaneously dry the metal powder during stirring, thus preventing the metal powder from agglomerating due to humidity. Furthermore, the use of crushing columns and crushing blocks during stirring breaks up the metal powder, enabling more uniform mixing of powders of different components and breaking up metal powder agglomerates. This ensures sufficient contact and dispersion of the ingredients within the metal powder, guaranteeing the uniformity of the metal powder composition after mixing and improving the stirring quality of the metal powder after mixing.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1-6The present invention provides a batching and mixing device for preventing metal powder agglomeration, including a mixer body 1 and a drive shaft 2. The drive shaft 2 is fixedly connected to the inside of the mixer body 1. Multiple casters 4 are symmetrically fixedly connected to the bottom end of the mixer body 1. A mixing tank body 5 is fixedly connected inside the mixer body 1. The mixing tank body 5 is located below the drive shaft 2.

[0030] An anti-agglomeration component 3 is provided at the bottom of the drive shaft 2, and part of the outer surface of the anti-agglomeration component 3 is located inside the mixing tank body 5.

[0031] In this embodiment, the anti-agglomeration component 3 is used to crush and stir the metal powder during stirring, which can make the powders of different components more uniformly mixed. At the same time, it can break up the metal powder agglomerates, so that the ingredients in the batch and the metal powder can fully contact and disperse, thereby ensuring the uniformity of the metal powder components after batching, and thus improving the stirring quality of the metal powder after batching.

[0032] When the user needs to move this utility model, the user can easily change the placement position of this utility model with the help of the casters 4 at the bottom of the mixer body 1, so that the user can reasonably arrange the placement space of this utility model.

[0033] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the shielding assembly 6 includes a shielding plate 61 and a mounting plate 62 disposed at the top of the mixing tank body 5. The top of both the shielding plate 61 and the mounting plate 62 are provided with cylindrical grooves for the stirring shaft 31 to pass through. A plug 63 is fixedly connected to the side of the shielding plate 61 near the mounting plate 62. A slot adapted to the plug 63 is provided on the side of the mounting plate 62 near the shielding plate 61.

[0034] In this embodiment, the user can manually pull the baffle plate 61 or the mounting plate 62 away from the stirring shaft 31 to remove the obstruction of the top of the mixing tank body 5. The user then pours the metal powder and other ingredients into the mixing tank body 5. Afterward, the user reinserts the insert 63 into the slot on the mounting plate 62, restoring the baffle plate 61 and mounting plate 62 to their original positions. Figure 2 As shown, the shielding plate 61 and the mounting plate 62 can block the top of the mixing tank body 5 during subsequent mixing to prevent metal powder and ingredients from splashing into the mixing environment. This helps to reduce the waste of metal powder during the mixing process and also prevents moisture in the air from entering the mixing tank body 5, thereby preventing moisture from interfering with the mixing of metal powder.

[0035] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the anti-agglomeration component 3 includes a stirring shaft 31 fixedly connected to the bottom end of the drive shaft 2. A drain port 32 is provided on the outer surface of the stirring shaft 31. A dehumidification component 7 and a shielding component 6 are provided on the outer surface of the stirring shaft 31. The shielding component 6 is located at the top of the mixing tank body 5. An inlet cavity is provided inside the stirring shaft 31. A stirring plate 33 is fixedly connected to the outer surface of the stirring shaft 31. A heating cavity is provided inside the stirring plate 33. An inlet port is provided on the outer surface of the stirring shaft 31, communicating with both the inlet port and the inlet cavity, and communicating with the heating cavity. The outer periphery of the stirring shaft 31 is fixed at equal angles. Multiple crushing columns 34 are connected and located below the stirring plate 33. Multiple crushing blocks 35 are fixedly connected to the outer surface of the crushing columns 34. The crushing blocks 35 are arranged in an alternating manner on the outer surface of the crushing columns 34. The dehumidification component 7 includes a guide ring 72 rotatably connected to the outer surface of the stirring shaft 31. A drainage cavity is opened inside the guide ring 72. A drainage hole 73 is opened on the inner surface of the guide ring 72. The drainage hole 73 communicates with the drainage cavity and the drainage port 32. An inlet pipe 71 is fixedly connected to the outer surface of the guide ring 72 and communicates with the drainage cavity.

[0036] In this embodiment, as Figure 4 and Figure 6 As shown, before placing the metal powder inside the mixing tank body 5, the user needs to connect an external heat source to the inlet pipe 71 so that the heat from the heat source enters the inlet pipe 71. The heat enters the drainage chamber in the guide ring 72 from inside the inlet pipe 71. The heat enters the inlet chamber in the mixing shaft 31 through the drainage hole 73 and the drainage port 32. The heat enters the heating chamber in the mixing plate 33 through the inlet on the outer surface of the mixing shaft 31 from the inlet in the mixing shaft 31. The heat in the heating chamber heats the outer surface of the mixing plate 33, thereby dehumidifying the metal powder during subsequent mixing to prevent the metal powder from agglomerating due to moisture, thus ensuring the mixing quality of the metal powder after batching.

[0037] Before stirring the metal powder, the user turns on the power to the mixer body 1, causing the mixer body 1 to drive the drive shaft 2 to rotate. When the drive shaft 2 rotates, it drives the stirring shaft 31 to rotate. When the stirring shaft 31 rotates, it drives the stirring plate 33 to rotate. Thus, the heated stirring plate 33 is used to stir the metal powder, reducing the moisture and gas content adsorbed on the surface of the metal powder, reducing the capillary force caused by moisture and the interparticle force caused by gas, thereby reducing the possibility of powder agglomeration. At the same time, the appropriate temperature helps to enhance the thermal motion of the metal powder particles, making the particles easier to disperse evenly under the stirring action, and improving the dispersibility of the powder.

[0038] In the stirring of metal powder, the stirring shaft 31 drives the crushing column 34 to rotate when it rotates, and the crushing column 34 drives the crushing block 35 to rotate when it rotates. The crushing block 35 crushes the metal powder when it rotates, and at the same time breaks up the metal powder agglomerates, so that the ingredients in the batch and the ingredients in the metal powder can fully contact and disperse, thereby ensuring the uniformity of the ingredients in the metal powder after batching, and thus improving the stirring quality of the metal powder after batching, which is beneficial to improving the fluidity and filling properties of the metal powder.
