[0034] In the following, only some exemplary embodiments are briefly described.

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0036] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0037] See also Figure 1 and Figure 2, an aluminum liquid crystal grain refinement mechanism, comprising a flow channel 1, a partition 2, a main shaft 3, a baffle 4, a diverter plate 5, a driving assembly (not shown in the figure) and an ultrasonic generator 6. The flow channel 1 is a long strip structure and is arranged in an inclined shape. The top of the flow channel 1 is open, and one end is connected to the discharge part of the aluminum liquid, such as the output part of the aluminum electrolytic cell, or the pouring outlet of the water bag.

[0038] The partition 2 is arranged in the flow channel 1, and the length direction of the partition 2 is consistent with the extension direction of the flow channel 1. There is a gap between the two sides of the partition 2 and the two side walls in the flow channel 1, and two vibration parts are formed between the two sides of the flow channel 1 and the two sides of the partition 2, and are respectively set as the first vibration part and the second vibration part.

[0039] Two main shafts 3 are respectively arranged above the flow channel 1, and the two main shafts 3 are rotatably connected to the flow channel 1. At the same time, the axes of the two main shafts 3 are collinear, the axes of the main shafts 3 are parallel to the bottom surface of the flow channel 1, and the two main shafts 3 are respectively located above the two vibration parts.

[0040] A baffle plate 4 is respectively arranged on the two main shafts 3 , and the two baffle plates 4 can respectively block the two vibration parts, so that the two vibration parts become a container structure.

[0041] The splitter plate 5 is arranged on one end of the baffle plate 4 , and the splitter plate 5 and the baffle plate 4 are rotatably connected.

[0042] The driving component has three output ends, two of which are respectively connected to one end of the two main shafts 3, and the other is connected to the rotating shaft of the diverter plate 5, so that the rotating axis of the diverter plate 5 is perpendicular to the bottom surface of the flow channel 1.

[0043] There are at least two ultrasonic generators 6, and at least one is disposed in each of the two vibration parts.

[0044] Preferably, the mouth width of the flow channel 1 is greater than its bottom width, and the two sides of the partition 2 are inclined structures so that the width of one end connected to the bottom of the flow channel 1 is greater than the width of the other end. The baffle 4 is a trapezoidal structure. In addition, the baffle 4 and the diverter plate 5 are respectively located at the two ends of the partition 2.

[0045] For the convenience of the following description, the two baffles 4 are respectively the first baffle and the second baffle, the two main shafts 3 are respectively the first main shaft and the second main shaft, and the three output ends of the driving component are respectively the first output end, the second output end and the third output end, wherein the first output end of the driving component is dynamically connected to one end of the first main shaft, the second output end is dynamically connected to one end of the second main shaft, and the third output end is dynamically connected to the rotating shaft of the diverter plate 5. In addition, the first main shaft is connected to the first baffle, the second main shaft is connected to the second baffle, the first baffle is located in the first vibration part, and the second baffle is located in the second vibration part.

[0046] During operation, one end of the flow channel 1 is connected to the output port of an aluminum electrolysis cell or other aluminum liquid container, and aluminum liquid is continuously fed into the flow channel 1 .

[0047] A first main shaft is driven to rotate through the first output end of the driving component, so that the first baffle blocks the first vibrating part, and the diverter plate 5 is driven to rotate through the third output end of the driving component, so that the diverter plate 5 isolates the second vibrating part, so that the aluminum liquid can only enter the first vibrating part and fill the first vibrating part.

[0048] Then, the second output end of the driving component drives the second main shaft to rotate, so that the second baffle blocks the second vibration part. After completion, the third output end of the driving component drives the diverter plate 5 to rotate, isolates the first vibration part, so that the aluminum liquid can only enter the second vibration part, and at the same time, the aluminum liquid in the first vibration part is vibrated by the ultrasonic generator 6.

[0049] The time for the aluminum liquid to fill the vibration part is set to be exactly twice the vibration time of the aluminum liquid in the vibration part.

[0050] When the aluminum liquid in the first vibration part reaches the vibration time, the first output end of the driving component drives the first main shaft to rotate, so that the first baffle opens the first vibration part and releases the aluminum liquid in the first vibration part. When it is completely released, the second vibration part is just filled with aluminum liquid. At the same time, the diverter plate 5 and the first main shaft rotate to guide the aluminum liquid into the first vibration part again.

[0051] In this embodiment, the above-mentioned actions are repeated to efficiently complete the refinement of aluminum liquid crystal particles.

[0052] In a preferred technical solution, one end of the baffle 4 is fixedly connected to the cylindrical surface of the main shaft 3. By connecting the baffle 4 to the cylindrical surface of the main shaft 3, a part of the main shaft 3 can also become a mechanism for blocking the flow of aluminum liquid.

[0053] In a preferred technical solution, the drive assembly includes three servo motors, and the output shafts of the three servo motors are respectively the three output ends of the drive assembly. Therefore, the output shafts of the three servo motors are respectively connected to one end of the two main shafts 3 and one end of the rotating shaft of the diverter plate 5.

[0054] By setting three servo motors, the rotation direction and rotation angle of the two baffles 4 and the diverter plate 5 can be accurately controlled.

[0055] In a preferred technical solution, at least one baffle 4 is located in the vibration part at the same time to cut off the vibration part, but if the first baffle is not located in the first vibration part, the diverter plate 5 covers the end of the first vibration part. This set structure can prevent aluminum liquid from being leaked.

[0056] Preferably, in a technical solution,

[0057] The rotating shaft of the diverter plate 5 is rotatably arranged at the end of the partition plate 2, and a connecting shaft is also horizontally arranged on the flow channel 1. A pair of bevel gears are arranged between the connecting shaft and the rotating shaft. An output end of the driving component is dynamically connected to one end of the connecting shaft. By setting the connecting shaft, a servo motor in the driving component can be installed at a position away from the flow channel 1, thereby reducing the influence of the high temperature of the aluminum liquid on the servo motor.

[0058] In a preferred technical solution, the length of the diverter plate 5 is greater than 1.5 times the width of the vibrating portion, thereby reducing the impact force of the aluminum liquid on the diverter plate 5 after the end of the diverter plate 5 away from the rotating shaft contacts the inner wall of the flow channel 1.

[0059] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
