Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a grain refinement device for aluminum material crystallization, comprising a frame 1;

[0025] A thinning tank 2 is mounted on the frame 1, and a rotating shaft 3 is rotatably arranged in the thinning tank 2;

[0026] The bottom of the frame 1 is equipped with a conveying assembly 9, which includes a collecting seat 91 arranged below the thinning tank 2;

[0027] A base is provided on one side of the frame 1, and a secondary refinement component 10 is provided on the base. A plurality of stirring impellers 101 are rotatably provided in the secondary refinement component 10;

[0028] A plurality of mounting plates 4 are provided at intervals outside the rotating shaft 3 , and a plurality of thinning plates 5 are provided around the outside of the plurality of mounting plates 4 along the center of the circle.

[0029] In the present embodiment, in the actual refinement operation, the rotating shaft 3 is arranged to drive the mounting disk 4 and the refinement plate 5 to rotate, and then the aluminum crystal raw material is preliminarily stirred and refined through the refinement plate 5 and the mounting disk 4; at the same time, through the arrangement of the conveying component 9, after the aluminum crystals are refined in the refinement tank 2 for a period of time, the aluminum crystals that meet the first refinement specifications will fall into the conveying seat 93 through the mesh screen 92, and at the same time be conveyed to the secondary refinement component 10 by the spiral blades 94. At this time, the stirring impeller 101 collides with the rotation of the aluminum crystals, and then the secondary refinement of the aluminum crystals is realized in the secondary refinement component 10. Compared with the traditional single rolling process, the grain size of the aluminum can be further reduced through multiple refinement processes. The smaller grain size can improve the strength, plasticity and toughness of the material, and at the same time improve the wear resistance and corrosion resistance of the material. In addition, multiple refinement processes can promote the uniform distribution of the grains and reduce the size difference between the grains, which helps to improve the uniformity and consistency of the material.

[0030] Specifically, refer to Figure 1-2 A reduction motor 6 is mounted on the frame 1, and a driving wheel 7 is connected to the output end of the reduction motor 6. One end of the rotating shaft 3 passes through the thinning groove 2 and a transmission belt 8 is tensioned between the rotating shaft 3 and the driving wheel 7.

[0031] In this embodiment, when performing the refinement operation, the user connects the power supply to the reduction motor 6. At this time, through the drive of the reduction motor 6, in conjunction with the transmission connection between the driving wheel 7 and the rotating shaft 3, the set rotating shaft 3 can drive the installation disk 4 and the refinement plate 5 to rotate, and then the aluminum crystal raw material is stirred and refined in the refinement tank 2.

[0032] Specifically, refer to Figure 3-4 The collecting seat 91 is a hollow box structure and a mesh screen 92 is embedded on its upper end surface. The mesh screen 92 is provided with a plurality of meshes. The mesh screen 92 is arranged at the bottom of the refinement tank 2 and is connected to the refinement tank 2.

[0033] In this embodiment, after the aluminum crystal raw material is stirred and refined in the refinement tank 2, and after a period of refinement, the mesh on the screen 92 is opened, and the aluminum crystals that meet the first refinement specifications will fall through the mesh of the screen 92 into the conveying seat 93, and then be conveyed to the secondary refinement component 10 through the conveying seat 93 for secondary refinement.

[0034] Specifically, refer to Figure 3-4 A conveying seat 93 is connected to one side of the collecting seat 91, and a spiral blade 94 is rotatably arranged inside the conveying seat 93. One end of the spiral blade 94 passes through the collecting seat 91 and is connected to a matching wheel 941. A belt 95 is tensioned between the matching wheel 941 and the outside of the rotating shaft 3.

[0035] In this embodiment, by setting a belt 95 between the matching wheel 941 and the rotating shaft 3, when the rotating shaft 3 is rotating, the matching wheel 941 can drive the spiral blade 94 to rotate synchronously. At this time, when the spiral blade 94 is rotating, the fine aluminum crystals in the conveying seat 93 can be conveyed to the secondary refining component 10 for secondary refining treatment.

[0036] Specifically, refer to Figure 1-4 A motor is installed on the side of the secondary refinement component 10, and the output end of the motor passes through the secondary refinement component 10 and is connected to the center of the stirring impeller 101.

[0037] In this embodiment, in the actual thinning operation, when the aluminum crystals reaching the first thinning specification fall into the conveying seat 93, the refined crystals can be conveyed to the secondary thinning component 10 through the rotation of the spiral blades 94. At this time, the user connects the power supply to the motor on the secondary thinning component 10 so that the motor drives the stirring impeller 101 to rotate. The stirring impeller 101 continuously rotates and collides with the aluminum crystals, thereby realizing the secondary thinning treatment of the aluminum crystals in the secondary thinning component 10.

[0038] Specifically, refer to Figure 1-4 A discharge port 102 is provided on one side of the secondary refinement component 10 .

[0039] In this embodiment, the user can set a fan at the port of the discharge port 102 for extraction operation. After the secondary refinement treatment of the aluminum grains is completed in the secondary refinement component 10, the extraction of the fan and the continuous rotation of the stirring impeller 101 allow the fine grains to be extracted through the discharge port 102, thereby completing the extraction operation of the aluminum grains.

[0040] The grain refinement device of aluminum material crystallization of the utility model:

[0041] Step 1: When the user is refining the aluminum crystals, the aluminum crystals to be processed are poured from the opening of the refining tank 2 into the refining tank 2, and then the reduction motor 6 is connected to the power supply. At this time, the reduction motor 6 is driven to cooperate with the transmission connection between the driving wheel 7 and the rotating shaft 3, so that the rotating shaft 3 can drive the installation plate 4 and the refining plate 5 to rotate, and then the aluminum crystal raw materials are stirred and refined. After a period of refining, the aluminum crystals that meet the first refining specifications will fall into the conveying seat 93 through the mesh screen 92;

[0042] Step 2: Due to the transmission connection between the spiral blade 94 and the rotating shaft 3, when the rotating shaft 3 is rotating, the set spiral blade 94 will keep rotating in the conveying seat 93 synchronously. At the same time, when the aluminum crystals reaching the first refinement specification fall into the conveying seat 93, the refined crystals can be conveyed to the secondary refinement component 10 through the rotation transmission of the spiral blade 94. Then the user connects the power supply to the motor on the secondary refinement component 10 so that the motor drives the stirring impeller 101 to rotate. The stirring impeller 101 collides with the rotation of the aluminum crystals, thereby realizing the secondary refinement treatment of the aluminum crystals. After the treatment, the aluminum crystal grains can be extracted and taken away through the discharge port 102.
