Description

Technical Field

[0001] The utility model belongs to the technical field of material mixing and relates to a three-dimensional motion mixer. Background Art

[0002] The three-dimensional motion mixer is a kind of mixer, which is used for high-uniformity mixing of powdery and granular materials in pharmaceutical, chemical, food, light industry, electronics, machinery, mining and research units.

[0003] The existing three-dimensional motion mixer products have been widely applied. The mixing with multi-directional rotation actions has certain advantages. However, due to the limitations of its own motion structure, the rotation action rate is limited, resulting in limited impact mixing force between the internal contents. Especially when there are large differences in the specific gravity of the mixed contents or when they are prone to agglomeration and caking, the mixing effect is still not ideal. For example, for the three-dimensional motion mixer disclosed in the Chinese utility model patent CN219596417U, although a stirring rod structure is further added inside on the basis of the mixer, since the problem of limited impact mixing force is not solved, it still cannot handle well the situations of large differences in the specific gravity of the contents and easy agglomeration and caking.

[0024] The present utility model provides a three-dimensional motion mixer. Referring to Figure 1 , it includes a frame 1, a mixing tank, and double swing arms. The mixing tank is arranged on one side of the frame 1. The double swing arms include a first swing arm 31 and a second swing arm 32 respectively connected to both ends of the mixing tank. The first swing arm 31 and the second swing arm 32 are both hinged to the mixing tank. A first drive shaft and a second drive shaft are respectively arranged on the frame 1. The first swing arm 31 and the second swing arm 32 are respectively hinged to the first drive shaft and the second drive shaft. A drive motor for driving the first drive shaft and the second drive shaft to rotate is arranged inside the frame 1. When the drive motor drives the first drive shaft and the second drive shaft to rotate, the mixing tank can be driven to perform three-dimensional tumbling actions by linking the actions of the first swing arm 31 and the second swing arm 32. The three-dimensional motion principle of the mixing tank refers to the structural principle of the three-dimensional motion mixer disclosed in the prior art, so no more elaboration will be made here.

[0025] The mixing tank includes a tank body 21, with a feed inlet 22 and a discharge outlet 23 respectively provided at both ends of the tank body 21. The feed inlet 22 and the discharge outlet 23 are both provided with cover plate structures that can be opened and closed to achieve feeding and discharging of the mixing tank. Among them, a feed cover plate 4 is provided at the feed inlet 22. The feed cover plate 4 is cover - set on the feed inlet 22 to close it. An arc - shaped protrusion 25 is provided on the periphery of the feed inlet 22, and an arc groove for accommodating the arc - shaped protrusion 25 is provided on the periphery of the feed cover plate 4. When the feed cover plate 4 is cover - set on the feed inlet 22, the arc groove and the arc - shaped protrusion 25 are in contact and cooperate to limit the offset of the feed cover plate 4 relative to the feed inlet 22. Preferably, the arc - shaped protrusion 25 and the arc groove are provided in two opposite groups to ensure full coincidence when the feed cover plate 4 and the feed inlet 22 are cover - set, guaranteeing stability and tightness.

[0026] A handle 42 for users to grip is provided on the feed cover plate 4.

[0027] A locking structure 24 is provided on the outer periphery of the feed inlet 22. The locking structure 24 includes a locking seat, a locking rod, and a locking cap. The locking seat is fixedly provided at the bottom of the outer periphery of the feed inlet 22. One end of the locking rod is hinged to the locking seat, and the other end is thread - connected to the locking cap. A notch is provided on the feed cover plate 4. The locking rod can enter the notch during rotation along the hinge axis. When the locking rod is in the notch, the relative rotation of the locking cap and the locking rod can make the locking cap move towards the direction of the feed cover plate 4 until the locking cap abuts against the outer surface of the feed cover plate 4, and it is tightly pressed against the feed cover plate 4 with continuous rotation, tightly fitting and fixing the feed cover plate 4 on the feed inlet 22.

[0028] Refer to Figure 2 and Figure 3 , an inner tube 41 is further provided on the inner side of the feed cover plate 4. When the feed cover plate 4 is cover - set on the feed inlet 22, the inner tube 41 extends into the tank body 21 from the feed inlet 22. A hollow cavity is formed in the inner tube 41. One end of the hollow cavity communicates with an opening provided on the outer surface of the feed cover plate 4. A vibration device can be provided in the hollow cavity. Preferably, the vibration device is a high - frequency vibrating rod 6. The high - frequency vibrating rod 6 enters the hollow cavity along the opening. When the mixing tank is in the mixing operation, the start of the high - frequency vibrating rod 6 can cause the vibration of the inner inner tube 41, thereby affecting the mixture to make it mix more fully.

[0029] An installation frame 5 is also inserted into the hollow cavity. The high-frequency vibrating rod 6 is inserted through one end of the installation frame 5 and fixed to the installation frame 5. Specifically, a clamping groove is provided on the installation frame 5, and an opening for the high-frequency vibrating rod 6 to be squeezed and embedded is formed on one side of the clamping groove. The installation frame 5 is inserted into the hollow cavity along the axial direction of the inner pipe 41, and the peripheral wall of the installation frame 5 is attached to the peripheral wall of the hollow cavity. While forming a stable limit support for the high-frequency vibrating rod 6, the vibration generated by it is transmitted to the outside of the inner pipe 41 more smoothly and without loss. The other end of the installation frame 5 can be fixedly connected to the feed cover plate 4, which can be a bolt connection type of fixation.

[0030] Further, a sleeve 27 is also provided in the tank body 21. The sleeve 27 has a hollow columnar structure. The sleeve 27 is fixedly connected to the inner wall of the tank body 21. When the feed cover plate 4 covers the feed port 22 and the inner pipe 41 enters the tank body 21, the inner pipe 41 passes through the hollow part of the sleeve 27, and the outer wall of the inner pipe 41 is attached to the inner wall of the sleeve 27, so that the vibration can be transmitted to the sleeve 27. An outward expansion part 26 extending radially along the sleeve 27 is provided on the outer periphery of the sleeve 27. The outward expansion part 26 can be in a spiral blade-like structure along the axial direction of the sleeve 27, or can be set as a rod-like structure with multiple branches. The branch rod-like structures extend radially along the sleeve 27 at different positions in the circumferential direction of the sleeve 27. The vibration can be transmitted from the sleeve 27 to the outward expansion part 26. Then, when the mixing tank is working, the outward expansion part 26 can fully contact the contents in the tank and transmit the vibration, so that the contents are broken and loosened to ensure full mixing.

[0031] The materials of the installation frame 5, the inner pipe 41, the sleeve 27 and the outward expansion part 26 are preferably metals to conduct vibration with high efficiency.

[0032] In another embodiment, a heating pipe can also be provided on the installation frame 5 for heating the contents in the mixing tank. The heat of the heating pipe is transmitted outward through the installation frame 5, the sleeve 27 and the outward expansion part 26.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
