Description

Technical Field

[0001] This application relates to the technical field of aluminum-based material processing, and particularly relates to a mixing device for nano-reinforced aluminum-based composites. Background Art

[0002] In the production and processing of new aluminum-based materials, it is often necessary to heat solid aluminum-based materials to stir and mix the new aluminum-based materials.

[0003] The patent document with publication number CN112619529A discloses a stirring and mixing device for the production and processing of new aluminum-based materials, including a stirring tank. A heating device is arranged inside the stirring tank to heat the aluminum-based materials; a stirring paddle is arranged in the stirring tank, and the stirring paddle is arranged on a rotating shaft that drives it to rotate. Since the aluminum-based materials have a certain density, the stirring paddle in the document cannot make the aluminum-based materials fully mixed and heated. Especially for the aluminum-based materials at the bottom of the stirring tank, the stirring paddle therein cannot stir the aluminum-based materials in the up and down directions, and the heating device is arranged above the entire aluminum-based materials, resulting in poor heating and mixing effects of the aluminum-based materials.

[0020] Now, the present application will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0021] As Figures 1-5 shown, the mixing device for nano-enhanced aluminum matrix composite material includes a mixing tank 1. A mixing collar 3 is provided at the bottom of the mixing tank 1. The mixing collar 3 is mounted on the bottom of the mixing tank 1. An annular cavity 4 is formed between the outer peripheral wall of the mixing collar 3 and the inner peripheral wall of the mixing tank 1. A rotating shaft 2 is provided inside the mixing collar 3. A stirring rod 5 is connected to the rotating shaft 2. A wave guide groove 31 is provided on the inner peripheral wall of the mixing collar 3. One end of the stirring rod 5 away from the rotating shaft 2 is slidably clamped in the wave guide groove 31. A lifting blade 40 is rotatably provided in the annular cavity 4.

[0022] The stirring sleeve ring 3 is a sleeve-like structure, in the shape of a column, with both ends open and the middle part connected.

[0023] The stirring tank 1 is also a columnar structure, with a cover on the top and a sealed bottom, and the mixing of the aluminum-based materials is completed inside the stirring tank 1.

[0024] A rotating shaft 2 is rotatably arranged in the stirring tank 1, and a bottom section of the rotating shaft 2 is located in the area surrounded by the stirring collar 3. One end of the stirring rod 5 is connected to the rotating shaft 2 and can shake and move up and down with the rotating shaft 2 to a certain extent.

[0025] When the stirring collar 3 is in the unfolded state, the wave guide groove 31 can be regarded as a wave-like structure, which is arranged on the inner wall of the stirring collar 3 and forms a circle. The other end of the stirring rod 5 is slidably engaged in the inside of the wave guide groove 31. When the rotating shaft 2 rotates, the stirring rod 5 rotates, and under the action of the wave guide groove 31, the stirring rod 5 not only performs circular motion, but also performs up and down reciprocating motion under the action of the wave guide groove 31, thereby fully mixing and stirring the aluminum-based material.

[0026] There is a certain interval between the outer wall of the stirring ring 3 and the inner wall of the stirring tank 1, that is, an annular cavity 4 is formed; a lifting blade 40 is provided in the annular cavity 4. When the lifting blade 40 moves, the aluminum-based material located at the bottom of the stirring tank 1 will be lifted upward from the annular cavity 4 to the surface of the entire aluminum-based material under the action of the lifting blade 40, thereby realizing the up and down flipping of the aluminum-based material to ensure the mixing effect.

[0027] Under the action of the lifting blade 40 and the movable stirring rod 5, the aluminum-based material can be mixed in the vertical direction in addition to the circumferential mixing, so that the aluminum-based material is mixed more evenly inside the stirring tank 1 and heated more evenly, further ensuring the processing effect of the aluminum-based material.

[0028] In some further embodiments, the outer peripheral wall of the rotating shaft 2 is provided with an arc-shaped connecting rod 20, and both ends of the arc-shaped connecting rod 20 are connected to the outer wall of the rotating shaft 2; the end of the stirring rod 5 is provided with a connecting ring 50, and the arc-shaped connecting rod 20 passes through the connecting ring 50.

[0029] The connecting ring 50 at one end of the stirring rod 5 is penetrated by the arc-shaped connecting rod 20, so that the stirring rod 5 has a certain amount of shaking relative to the rotating shaft 2, and also enables the stirring rod 5 to move to a certain extent in the up and down directions.

[0030] In some further embodiments, the cross section of the wave guide groove 31 is T-shaped.

[0031] Specifically, the cross section of the wave guide groove 31 is T-shaped, so that the other end of the stirring rod 5 can be well clamped to avoid slipping.

[0032] The wave guiding groove 31 is formed by two side walls 32 and a cover plate 33, and the cover plate 33 is fixed to the side walls 32 by bolts.

[0033] In some further embodiments, the lifting blade 40 is a screw blade, and the top of the screw blade is fixed to the rotating shaft 2.

[0034] Exemplarily, the lifting blade 40 is a screw blade, and the top of the screw blade is interconnected with the rotating shaft 2 through a fixing rod 41, so that the rotation of the screw blade and the rotation of the stirring rod occur simultaneously, thereby fully ensuring the treatment effect on the aluminum-based material.

[0035] In some further embodiments, a support rod 30 is provided at the bottom of the mixing tank 1, and the bottom of the mixing collar 3 is connected to the top of the support rod 30.

[0036] The erection between the mixing collar 3 and the mixing tank 1 is specifically realized through the support rod 30. The bottom of the support rod 30 is fixed to the bottom of the mixing tank 1, and the top of the support rod 30 is arranged at the bottom of the mixing collar 3.

[0037] In some further embodiments, the top of the rotating shaft 2 extends upward out of the mixing tank 1, and the top of the rotating shaft 2 is connected to the driving end of the motor 10.

[0038] The rotating shaft 2 is driven by the motor 10 provided at the top of the mixing tank 1.

[0039] The mixing tank 1 is also provided with a feed inlet 11 and a discharge outlet 12.

[0040] A heating device is further arranged inside the mixing tank 1 for heating the aluminum-based material. Since it is already relatively common in the field of aluminum-based material mixing devices and is prior art, its specific structure and working principle will not be described in detail in this embodiment.

[0041] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of this application.
