Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, and more particularly to a high-speed shear mixer for plant powders. Background Technology

[0002] In the food, pharmaceutical, and chemical industries, the mixing and processing of plant powders is a common process. Existing mixers (such as V-type mixers, three-dimensional mixers, and ribbon mixers) often result in plant powders adhering to the inner walls of the mixer during mixing, forming a buildup layer due to electrostatic adsorption or humidity. Traditional mixers lack self-cleaning designs, requiring frequent shutdowns for manual cleaning, which affects production efficiency, and the residual material may deteriorate and contaminate new batches.

[0003] Furthermore, plant powder has a low density and is prone to stratification during mixing. The bottom layer of material has poor flowability and is difficult for the stirring device to fully agitate, resulting in insufficient mixing uniformity (e.g., coefficient of variation CV > 5%), which affects the consistency of product quality. To address this, this solution proposes a high-speed shear mixer for plant powder. Utility Model Content

[0004] The high-speed shear mixer for plant powder proposed in this utility model solves the problems of untimely cleaning of materials adhering to the inner wall of the mixer and uneven mixing of the bottom layer materials in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-speed shear mixer for plant powder includes a mixing tank, a feeding hopper installed on the top of the mixing tank, and a stirring mechanism and a mixing mechanism installed inside the mixing tank;

[0007] The stirring mechanism includes a stirring shaft rotatably connected to the inner wall of the top of the mixing tank along the axial direction and multiple stirring rods fixed to the outer periphery of the stirring shaft;

[0008] The mixing mechanism includes a movable gear ring rotatably connected to the inner ring of the mixing tank, multiple screw conveyors rotatably connected to the bottom of the movable gear ring along the axial direction of the mixing tank, and a transmission assembly installed on the mixing tank for driving the movable gear ring to rotate when the stirring shaft rotates.

[0009] The mixing mechanism also includes a linkage component installed inside the mixing tank for driving the auger to rotate as it follows the moving gear ring in its revolution.

[0010] The above technical solution not only allows the bottom material to be transported to the top layer for further mixing during the mixing process, thereby improving the mixing effect, but also allows the material adhering to the inner wall of the mixing tank to be scraped off during the mixing process.

[0011] As a further improvement to the above solution, the bottom of the mixing tank is provided with a discharge port, and the bottom of the mixing tank is provided with a sealing plate for sealing the discharge port. The outer periphery of the mixing tank is rotatably connected to a fixed shaft that is fixed to the sealing plate. A handle is fixed to the outer periphery of the fixed shaft. When the fixed shaft rotates, it drives the sealing plate to rotate, so as to open or close the discharge port.

[0012] As a further improvement to the above solution, a transmission assembly for driving the stirring shaft to rotate is installed on the top of the mixing tank. The transmission assembly includes a mounting bracket installed on the top of the mixing tank and a drive motor installed on the mounting bracket. The top of the stirring shaft extends to the top of the mixing tank and is fixedly connected to one end of the output shaft of the drive motor.

[0013] As a further improvement to the above solution, the transmission assembly includes a rotating shaft rotatably connected to the inner wall of the top of the mixing tank and a transmission gear fixed at the bottom of the rotating shaft and meshing with the inner ring of the movable gear ring. The top of the rotating shaft extends to the top of the mixing tank and is fixed with a driven wheel. The outer periphery of the stirring shaft is sleeved with a driving wheel located outside the mixing tank, and the driving wheel and the driven wheel are connected by a belt drive.

[0014] As a further improvement to the above solution, the top of the auger extends above the movable gear ring, and the linkage assembly includes a fixed gear ring fixed to the top of the mixing tank and a linkage gear fixed to the top of the auger. The fixed gear ring and the movable gear ring are coaxially arranged, and the linkage gear meshes with the outer ring of the fixed gear ring.

[0015] As a further improvement to the above solution, the outer ring of the auger abuts against the inner ring of the mixing tank, and the end of the stirring rod away from the stirring shaft does not touch the auger during rotation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a stirring mechanism and a mixing mechanism, the stirring mechanism stirs the materials in the mixing tank while driving the auger to rotate on its own axis while revolving around the central axis. This not only scrapes off the materials adhering to the inner wall of the mixing tank, but also transports the raw materials from the bottom of the mixing tank to the top, thereby further mixing the raw materials and ensuring the uniformity of the mixed materials.

[0018] 2. By setting up transmission components and linkage components, the purpose of facilitating the simultaneous revolution and rotation of the auger while the stirring shaft is rotating is achieved. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figure 1 - Figure 3 The high-speed shear mixer for plant powder in this embodiment includes a mixing tank 1, a feeding hopper 2 installed on the top of the mixing tank 1, and a stirring mechanism and a mixing mechanism installed inside the mixing tank 1. The raw materials are fed into the mixing tank 1 through the feeding hopper 2 and then mixed evenly under the action of the stirring mechanism. The mixing mechanism is set to transport the material at the bottom of the mixing tank 1 to the top of the mixing tank 1 while stirring, thereby further improving the uniformity of the raw material mixing, and also scraping off the material adhering to the inner wall of the mixing tank 1.

[0027] The stirring mechanism includes a stirring shaft 12 rotatably connected to the inner wall of the top of the mixing tank 1 along the axial direction and a plurality of stirring rods 13 fixed to the outer periphery of the stirring shaft 12. A transmission assembly for driving the stirring shaft 12 to rotate is installed on the top of the mixing tank 1. The transmission assembly includes a mounting bracket 4 installed on the top of the mixing tank 1 and a transmission motor 3 installed on the mounting bracket 4. The top of the stirring shaft 12 extends to the top of the mixing tank 1 and is fixedly connected to one end of the output shaft of the transmission motor 3. After the transmission motor 3 rotates, it drives the stirring shaft 12. After the stirring shaft 12 rotates, it drives the plurality of stirring rods 13 to rotate inside the mixing tank 1, thereby relying on the high-speed rotation to perform high-speed shearing and mixing of the raw materials in the mixing tank 1.

[0028] The mixing mechanism includes a movable gear ring 9 rotatably connected to the inner ring of the mixing tank 1, multiple augers 10 rotatably connected to the bottom of the movable gear ring 9 along the axial direction of the mixing tank 1, and a transmission assembly mounted on the mixing tank 1 to drive the movable gear ring 9 to rotate when the stirring shaft 12 rotates. The transmission assembly includes a rotating shaft 17 rotatably connected to the inner wall of the top of the mixing tank 1 and a transmission gear 11 fixed to the bottom of the rotating shaft 17 and meshing with the inner ring of the movable gear ring 9. The top of the rotating shaft 17 extends to the top of the mixing tank 1 and is fixed with a driven wheel 5. The outer periphery of the stirring shaft 12 is fitted with a driving wheel located outside the mixing tank 1, and the driving wheel and the driven wheel 5 are connected by a belt drive. When the stirring shaft 12 rotates, it drives the driven wheel 5 to rotate through the belt. After the driven wheel 5 rotates, it drives the rotating shaft 17 to rotate. After the rotating shaft 17 rotates, it drives the transmission gear 11 to rotate. The transmission gear 11 then drives the movable gear ring 9 to rotate, thereby driving the augers 10 to rotate inside the mixing tank 1.

[0029] The mixing mechanism also includes a linkage component installed inside the mixing tank 1 to drive the auger 10 to rotate on its own axis while following the revolving ring 9. The top of the auger 10 extends above the revolving ring 9. The linkage component includes a fixed ring 8 fixed to the top of the mixing tank 1 and a linkage gear 16 fixed to the top of the auger 10. The fixed ring 8 and the revolving ring 9 are coaxially arranged, and the linkage gear 16 meshes with the outer ring of the fixed ring 8. When the revolving ring 9 rotates, it drives the auger 10 to revolve around the stirring shaft 12 as the center of rotation. At the same time, since the fixed ring 8 remains stationary, the linkage gear 16 will rotate on its own axis under the action of the fixed ring 8 while following the rotation of the auger 10, thereby achieving the purpose of driving the auger 10 to rotate on its own axis while the revolving ring 9 rotates.

[0030] In this embodiment, a discharge port 14 is provided at the bottom of the mixing tank 1, and a sealing plate 15 for sealing the discharge port 14 is provided at the bottom of the mixing tank 1. A fixed shaft 6 is rotatably connected to the outer periphery of the mixing tank 1 and fixed to the sealing plate 15. A handle 7 is fixed to the outer periphery of the fixed shaft 6. When the fixed shaft 6 rotates, it drives the sealing plate 15 to rotate, thereby opening or closing the discharge port 14. The discharge port 14 is provided to discharge the material in the mixing tank 1. When the handle 7 is held and the fixed shaft 6 is rotated, the sealing plate 15 will rotate, thereby opening or closing the discharge port 14.

[0031] Example 2:

[0032] Combination Figure 2 Based on Example 1, this embodiment is further improved in that: the outer ring of the auger 10 abuts against the inner ring of the mixing tank 1, the end of the stirring rod 13 away from the stirring shaft 12 does not touch the auger 10 during rotation, and the auger 10 cleans the inner wall of the mixing tank 1 during its rotation and revolution, thereby achieving the purpose of scraping off the material adhering to the inner wall of the mixing tank 1.
