[0033] In pharmaceutical, chemical, food, light industry, electronics, machinery, mining and metallurgy, defense industry, and scientific research institutions, there is a need to mix powdery and granular materials. Mixing devices are equipment used to achieve this mixing. In traditional technology, material mixing is mainly achieved through container equipment equipped with a stirring structure. This type of equipment has obvious mixing blind spots. In some technologies, the materials inside are mixed by driving the container to move. The mixing effect of this equipment is uneven, especially for components with large density differences, resulting in poor mixing effect and low mixing production efficiency.

[0034] The following is for reference only. Figure 1 To be continued Figure 5 The three-dimensional mixing device described in this utility model embodiment is capable of stirring and mixing raw materials in multiple dimensions, resulting in a comprehensive and uniform mixing effect and high mixing efficiency.

[0035] Reference Figures 1 to 5 A three-dimensional mixing device according to an embodiment of the present invention includes:

[0036] The base 100 is equipped with a drive mechanism 110;

[0037] The mixing tank 200 is provided with two mutually perpendicular first rotating shafts 210, and each first rotating shaft 210 is perpendicular to the central axis of the mixing tank 200. Along the extension direction of the central axis of the mixing tank 200, the two first rotating shafts 210 are respectively located on two different radial surfaces of the mixing tank 200. A stirring longitudinal rod 220 is rotatably connected in the mixing tank 200. The stirring longitudinal rod 220 is located in the mixing tank 200 and collinear with the central axis of the mixing tank 200. A plurality of stirring cross rods 230 are rotatably connected to the stirring longitudinal rod 220 and the stirring cross rods 230. Each stirring cross rod 230 is connected to a stirring blade 240. Preferably, the stirring blade 240 is connected to the end of the stirring cross rod 230. Under the action of the gravity of the stirring blade 240, the stirring cross rod 230 can rotate relative to the stirring longitudinal rod 220, and the stirring longitudinal rod 220 can rotate relative to the mixing tank 200.

[0038] The swing assembly 300 has two sets, each connected to two corresponding first rotating shafts 210. Each set of swing assemblies 300 includes a positioning arm 310 and a positioning frame 320. The two ends of the positioning arm 310 are respectively provided with a second rotating shaft 311 and a third rotating shaft 312 that are perpendicular to each other in space. The second rotating shaft 311 is rotatably connected to the base 100, and the third rotating shaft 312 is rotatably connected to the positioning frame 320. The positioning frame 320 is rotatably connected to the corresponding first rotating shaft 210. For the same set of swing assemblies 300 and the corresponding connected first rotating shafts 210, the first rotating shaft 210, the second rotating shaft 311, and the third rotating shaft 312... In three-dimensional space, at least one second rotating shaft 311 is connected to the drive mechanism 110, which is perpendicular to each other. The drive mechanism 110 drives the second rotating shaft 311 to rotate to realize the three-dimensional oscillation of the mixing tank 200. The raw materials in the mixing tank 200 can not only be mixed under the oscillation of the mixing tank 200, but also the always drooping stirring blade 240 moves relative to the three-dimensional oscillating mixing tank 200, which can simultaneously stir the raw materials in the mixing tank 200. This can effectively improve the uniformity and comprehensiveness of the mixing. Moreover, the stirring action of the internal stirring structure is achieved by gravity cooperation, without the need for additional power equipment, which can effectively reduce the cost of the device and reduce operating costs.

[0039] The connection between the base 100 and the mixing tank 200 is achieved through three sets of rotating shafts. The drive mechanism 110 can drive the mixing tank 200 to achieve compound motions in three-dimensional space, including a combination of tumbling, deflection, and oscillation. This allows the raw materials in the mixing tank 200 to achieve three-dimensional mixing, effectively accelerating the flow and diffusion of the raw materials. Furthermore, the mixing tank 200 achieves multi-dimensional compound motions with irregular trajectories. Compared to simple single-dimensional rotation, this three-dimensional mixing device can effectively reduce the segregation and accumulation of raw materials caused by centrifugal force, thereby effectively improving the uniformity and reliability of mixing, resulting in higher mixing quality. In addition, the stirring longitudinal rod 220 and stirring transverse rod 230, which rotate freely around different dimensions, allow the stirring blades 240 to move under gravity. Under the action of adaptive downward movement, and in conjunction with the compound motion of the mixing tank 200, the stirring blade 240 can form a relative motion with the mixing tank 200, thereby stirring and mixing the raw materials in the mixing tank 200. It can effectively disperse the raw materials in the central area of ​​the mixing tank 200, thereby effectively improving the uniformity of the stirring and mixing action, the stirring effect is comprehensive and reliable, it can effectively shorten the stirring and mixing time, and the stirring and mixing efficiency is high. The shear angle between the stirring blade 240 and the mixing tank 200 changes continuously, which can further improve the stirring and mixing effect. Moreover, the stirring action of the stirring blade 240 is mainly driven by gravity, without the need for additional power equipment. Under the premise of the same stirring effect, it can effectively reduce energy consumption, reduce mixing production costs, and the device structure is simple, which can effectively reduce maintenance costs and equipment costs.

[0040] It should be noted that the positioning frame 320 is U-shaped. The first rotating shaft 210 includes two rotating shaft segments located on the same axis. Both rotating shaft segments in the same first rotating shaft 210 are connected to the outer peripheral surface of the mixing tank 200. The two ends of the positioning frame 320 are respectively rotatably connected to the two rotating shaft segments in the same first rotating shaft 210. The U-shaped positioning frame 320 can provide sufficient clearance for the movement of the mixing tank 200 and can effectively control the volume of the positioning frame 320, thereby saving the material cost of the positioning frame 320.

[0041] Understandably, the stirring blade 240 is U-shaped, with its two ends connected to the two ends of the stirring crossbar 230, effectively improving the stirring effect. The U-shaped stirring blade 240, with its two ends fixed to the two ends of the stirring crossbar 230 by high-strength bolts or welding, forms a closed loop structure. This structure is stable, reliable, and has a long service life. Furthermore, it can generate a bidirectional vortex field during stirring, effectively enhancing the shearing effect and thus improving the mixing effect.

[0042] It is understandable that the stirring blade 240 is provided with a clearance hole 241, through which raw materials can flow through. This not only improves the mixing uniformity between components of different densities, but also effectively reduces the resistance of blade oscillation, thereby increasing the oscillation amplitude of the blade relative to the raw materials, and thus effectively improving the stirring effect.

[0043] Understandably, a first bearing 221 is connected between the stirring rod 220 and the mixing tank 200. The first bearing 221 can improve the reliability of the relative rotational movement between the stirring rod 220 and the mixing tank 200. A second bearing 231 is connected between the stirring crossbar 230 and the stirring rod 220. The second bearing 231 can improve the reliability of the relative rotational movement between the stirring crossbar 230 and the stirring rod 220. The stirring action of the stirring blade 240 is stable and reliable.

[0044] Preferably, both the first bearing 221 and the second bearing 231 are sealed bearings, and the protection level can be improved by incorporating a built-in fluororubber seal ring.

[0045] It is understood that the mixing tank 200 is provided with a feeding port 250 and a discharge port 260 at opposite ends. The feeding port 250 is provided with a feeding valve 251 connected to the mixing tank 200. The feeding valve 251 is used to open or close the feeding port 250. The discharge port 260 is provided with a discharge valve 261 connected to the mixing tank 200. The discharge valve 261 is used to open or close the discharge port 260.

[0046] It is understood that the feeding valve 251 is a flip-top valve, and the discharging valve 261 is a butterfly valve. The sealing surface of the flip-top valve can be covered with a food-grade silicone gasket, while the butterfly valve can have a polytetrafluoroethylene layer on its sealing surface. Preferably, the feeding valve 251 and the discharging valve 261 can also be configured as other valves capable of achieving a sealing switch.

[0047] Understandably, referring to Figure 4 As shown, the drive mechanism 110 includes a motor 111, a drive wheel 112, a timing belt 113, and a driven wheel 114. The housing of the motor 111 is connected to the base 100, the drive wheel 112 is connected to the output end of the motor 111, and the driven wheel 114 is connected to the second rotating shaft 311. The timing belt 113 is wound around the drive wheel 112 and the driven wheel 114 so that the motor 111 can indirectly drive the second rotating shaft 311 to rotate, thereby driving the mixing tank 200 to swing.

[0048] By setting up a synchronization component to drive the second rotating shaft 311 via the motor 111, the installation layout can be convenient and the expandability is strong. Setting the motor 111 in the bottom area of ​​the base 100 can effectively lower the center of gravity of the overall device, thereby improving the stability of the device.

[0049] Specifically, the diameter of the driving wheel 112 is smaller than the diameter of the driven wheel 114, and the second rotating shaft 311 is connected to the rotating shaft of the driven wheel 114. By setting the diameter of the driving wheel 112 to be larger than the diameter of the driven wheel 114, the torque can be effectively amplified, enabling the motor 111 to drive the second rotating shaft 311 to rotate at a reduced speed. This effectively improves the reliability of the operation and extends the service life of the motor 111.

[0050] Understandably, referring to Figure 5 As shown, the drive mechanism 110 has two sets, and each set of drive mechanism 110 is connected to the corresponding second rotating shaft 311. The dual-motor dual-drive mechanism can effectively increase the frequency of mixing oscillation, thereby accelerating the mixing process and improving mixing production efficiency.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
