DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings of the specification.

[0018] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0019] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0020] Embodiment 1

[0021] Referring to Figure 1 - Figure 2 , which is the first embodiment of the present utility model. This embodiment provides a slag removal mechanism for copper liquid in an oxygen-free copper rod continuous casting machine set. The slag removal mechanism includes a clamping assembly. The clamping assembly includes a support plate 1. The support plate 1 is circular. At least two groups of clamping plate assemblies rotatably installed on the support plate 1 and a power mechanism for driving these clamping plate assemblies to open and close. In this embodiment, the clamping plate assemblies are set to five groups, and the five groups of clamping plate assemblies are arranged in a circumferential array with the axis of the support plate 1 as the axis. When the clamping plate assemblies approach each other, they perform the clamping action on the impurities. When the clamping plate assemblies move away from each other, they perform the action of releasing the impurities.

[0022] During use, first move the clamping assembly directly above the liquid storage tank 18, then place the clamping assembly into the opening of the liquid storage tank 18, and immerse the lower half area of the clamping plate assemblies into the copper liquid. The impurities in the copper liquid are concentrated at the opening of the liquid storage tank 18 after adding a slag coagulant, and the impurities coagulate. Then, through the power mechanism, each clamping plate assembly is closed. During the closing process of each clamping plate assembly, the bottom end of the clamping plate assembly approaches the middle of the opening, and the distance between the bottom ends of each clamping plate assembly decreases, thereby binding the coagulated impurities. Then, by removing the clamping assembly, the impurities can be fished out.

[0023] Embodiment 2

[0024] Referring to Figure 1 - Figure 2 , which is the second embodiment of the present utility model. This embodiment is based on Embodiment 1. This embodiment provides a slag removal mechanism for copper liquid in an oxygen-free copper rod continuous casting machine set. The power mechanism includes a power unit 1 2 fixedly connected to the support plate 1. The power unit 1 2 can adopt a cylinder, an oil cylinder, or an electric telescopic rod. The output end of the power unit 1 2 is a driving plate 3. The driving plate 3 is circular. In order to improve stability, the driving plate 3 is coaxially arranged with the support plate 1. At the same time, in order to improve the stability of the driving plate 3 during lifting, the power unit 1 2 is also coaxially arranged with the driving plate 3. The lifting of the driving plate 3 provides power for the opening and closing of the clamping plate assemblies.

[0025] The splint assembly includes a transition rod 4 rotatably connected to the support plate 1 and a receiving plate 5 provided on the transition rod 4. A number of notches are formed on the support plate 1, and a fixed shaft 6 is fixed at each notch. The transition rod 4 is rotatably connected to the fixed shaft 6, and the receiving plate 5 is fixedly connected to the transition rod 4. When the transition rod 4 rotates around the fixed shaft 6, the receiving plate 5 can rotate along with the transition rod 4;

[0026] The power mechanism further includes a driving rod 7 rotatably connected to the transition rod 4. The driving rod 7 is rotatably connected to the driving plate 3. One end of the driving rod 7 is rotatably connected to the middle of the transition rod 4, and the rotation connection point has a certain distance from the fixed shaft 6. At the same time, the outer diameter of the driving plate 3 is smaller than the outer diameter of the support plate 1, and the driving rod 7 is inclined. When the driving plate 3 moves up and down, under the pulling of the driving rod 7, the splint assembly rotates around the fixed shaft 6;

[0027] As a preferred solution of the present utility model, the receiving plate 5 is in a hollow shape, and the impurity receiving surface of the receiving plate 5 is larger than that of the transition rod 4. The purpose of such a setting is to increase the contact area between the receiving plate 5 and the condensed impurities to prevent the condensed impurities from falling during the movement. At the same time, the receiving plate 5 is set in a hollow shape, and the purpose of such a setting is to help the copper liquid flow out and reduce the accumulation of copper liquid between the condensed impurities and the receiving plate 5;

[0028] During use, the receiving plate 5 is in a vertical state and enters the copper liquid. The purpose of such a setting is to reduce the number of impurities entering the copper liquid due to the descent of the receiving plate 5. Then, operate the power unit 1 2 to move the driving plate 3 upward. Under the pulling of the driving rod 7, the receiving plate 5 and the transition rod 4 rotate around the fixed shaft 6, and the distance between the bottoms of the receiving plates 5 decreases, so that each receiving plate 5 can clamp the condensed impurities;

[0029] In order to further increase the condensed impurities that the receiving plate 5 can fish out, in the initial design, according to the size of the opening of the liquid storage tank 18, the receiving plate 5 is at the opening end, and the receiving plates 5 are arranged in a circumferential array.

[0030] Embodiment 3

The power unit 2 8 uses a cylinder, an oil cylinder or an electric telescopic rod, such as Figure 1 and Figure 2As shown, a substrate 9 is fixed to the output end of the power unit two 8. The substrate 9 is connected to the support plate 1 through a bracket 10. By controlling the expansion and contraction of the output end of the power unit two 8, the height of the clamping assembly can be controlled, so that the height of the clamping assembly can be automatically controlled without manual operation;

[0032] The slag removal mechanism further includes a moving mechanism for moving the lifting mechanism. Through the moving mechanism, the horizontal position of the lifting mechanism and the clamping assembly can be controlled. After the coagulated impurities are fished up, it is convenient to move the impurities to other positions to release the impurities;

[0033] The moving mechanism includes a fixed frame 11. The fixed frame 11 needs to be fixed, and the fixing method will not be elaborated here. The power unit two 8 is slidably arranged on the fixed frame 11. The power unit two 8 is fixedly connected with a sliding plate 12. The sliding plate 12 is slidably connected to the fixed frame 11 through an optical axis 13. The moving unit further includes a rotating shaft 14 rotatably connected to the fixed frame 11. The rotating shaft 14 is fixedly connected with a swing arm one 15. The swing arm one 15 is rotatably connected with a swing arm two 16. As Figure 1 and Figure 2 shown, the swing arm one 15 and the swing arm two 16 form a V shape. The swing arm two 16 is rotatably connected to the power unit two 8. One end of the rotating shaft 14 is fixed with a power unit three 17. The power unit three 17 is a servo motor. By driving the power unit three 17, the rotating shaft 14 and the swing arm one 15 can be rotated. With the cooperation of the swing arm two 16, the lifting mechanism and the clamping assembly can be driven to slide relative to the fixed frame 11;

[0034] During use, the horizontal position of the clamping assembly is controlled by controlling the power unit three 17, and the vertical position of the clamping assembly is controlled by controlling the power unit two 8. Through the cooperation of the lifting mechanism, the moving mechanism and the clamping assembly, the coagulated impurities are fished up and placed at a designated position.
