[0002] In order to understand the electrolyte composition, the quality of the original aluminum and the safety status of the electrolytic cell production process, daily sampling and analysis are required. There is a risk of high temperature burns. Hundreds of electrolyte samples and aluminum samples need to be taken out from the cell separately.

[0003] In the actual production process, separate sampling spoons are generally used for sampling, which is inefficient and multiple sampling undoubtedly increases the risk of burns. Utility Model Content

[0004] The utility model provides a 600KA electrolyte aluminum liquid sampling combination device to achieve rapid sampling of electrolyte and aluminum liquid, thereby improving work efficiency and reducing the risk of scalding. In order to achieve the above purpose, the technical solution adopted is as follows:

[0005] A 600KA electrolyte aluminum liquid sampling assembly device, characterized by comprising:

[0006] An operating rod, wherein a surface of the operating rod is provided with slide rails distributed along the length direction;

[0007] The sampling spoon includes a first sampling spoon and a second sampling spoon disposed above and below, wherein the first sampling spoon and the second sampling spoon are respectively fixedly connected to a connecting rod on one side, and a slider is fixedly connected to an end of the connecting rod away from the first sampling spoon or the second sampling spoon, and the slider is slidably connected to the slide rail along the length direction of the operating rod;

[0008] A locking assembly, connected between the slider and the slide rail, for fixing the position of the slider in the length direction of the operating rod;

[0009] The cover plate is arranged on the upper end opening of the second sampling spoon. The cover plate and the operating rod are connected to a rotating component for driving the cover plate to rotate to open or close the upper end opening of the second sampling spoon.

[0010] Furthermore, the locking assembly includes a fastening bolt, and a threaded hole is provided on the sliding block. The fastening bolt passes through the threaded hole and is tightened against the surface of the sliding rail.

[0011] Furthermore, a side surface of the slide rail close to the first sampling spoon and the second sampling spoon is a non-smooth friction surface.

[0012] Furthermore, the operating rod is provided with scale lines distributed along the length direction.

[0013] Furthermore, the rotating assembly includes a bearing, a rotating longitudinal rod and a rotating cross rod.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the viewing direction or position relationship, and are only for the convenience of describing the utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0027] In this embodiment, in order to explain the structure more clearly, Figure 1 The description is based on the viewing direction.

[0028] like Figure 1-Figure 3 The illustrated device is a 600KA electrolyte aluminum liquid sampling assembly, comprising an operating rod 1, a first sampling spoon 6, and a second sampling spoon 7. The length of the operating rod 1 is distributed in the vertical direction. The two sampling spoons are respectively connected to the operating rod 1 by sliding up and down, and the first sampling spoon 6 is located above the second sampling spoon 7. A cover plate 13 is provided on the second sampling spoon 7. A rotating assembly is connected between the cover plate 13 and the operating rod 1. The rotating assembly can drive the cover plate 13 to rotate, thereby opening the upper end surface opening of the second sampling spoon 7.

[0029] Specifically, a slide rail 2 is fixedly connected to the right side of the operating rod 1, and the length of the slide rail 2 is distributed in the vertical direction. The first sampling spoon 6 and the second sampling spoon 7 are connected to the slide rail 2 for sliding up and down through the connecting rod 5 and the slider 3. The right end of the connecting rod 5 is fixedly connected to the sampling spoon, and the left end is fixedly connected to the slider 3. The slider 3 is provided with a slide groove that cooperates with the slide rail 2, and threaded holes distributed left and right are also provided on the slider 3. The threaded holes are threadedly connected with fastening bolts 4. By tightening the fastening bolts 4 against the right side of the slide rail 2, the slider 4 can be fixed to the slide rail 2, thereby fixing the position of the sampling spoon in the height direction.

[0030] In order to further improve the fixing effect of the slider 3 and the slide rail 2, as shown in FIG. Figure 3 As shown, the right side of the slide rail 2 is set as a non-smooth friction surface 9. The fastening bolt 4 is tightened on the friction surface 9 to further increase the friction between the slider 3 and the slide rail 2, thereby improving the fixing effect between the two.

[0031] The rotating assembly is as follows Figure 1 As shown, it includes a bearing 10, a rotating longitudinal rod 11 and a rotating cross rod 12. The upper and lower ends of the rotating longitudinal rod 11 are rotatably connected to the upper and lower ends of the operating rod 1 through a group of bearings 10. Specifically, the rotating longitudinal rod 11 is fixedly connected to the outer ring of the bearing 10, and the operating rod 1 is fixedly connected to the inner ring of the bearing 10. The length of the rotating cross rod 12 is distributed in the horizontal direction, and its two ends in the length direction are fixedly connected to the cover plate 13 and the rotating longitudinal rod 11 respectively. By toggling the rotating longitudinal rod 11, the rotating longitudinal rod 11 can be rotated around the axis of the bearing 10, thereby driving the rotating cross rod 12 and the cover plate 13 to rotate, and then the upper end opening of the second sampling spoon 7 is opened. It should be noted that in this embodiment, as shown in FIG. Figure 1 In the direction of the view shown, the rotating cross bar 12 is located behind the operating rod 11 to avoid interference between the rotating cross bar 12 and the operating rod 1 during rotation. Moreover, when rotating, it is necessary to rotate counterclockwise to open the cover 13.

[0032] When entering the electrolytic cell from top to bottom, the setting of the cover 13 can prevent the upper electrolyte from entering the second sampling spoon 7. When the second sampling spoon 7 reaches the bottom aluminum liquid position, the first sampling spoon 6 reaches the upper electrolyte at the same time, and the electrolyte enters the first sampling spoon 6. The cover 13 can be driven to open by the rotating component, thereby completing the sampling of the bottom aluminum liquid.

[0033] In addition, in this embodiment, scale lines 8 are provided on the operating rod 1 along the length direction to facilitate adjustment of the height of the two sampling spoons and the distance between them. The upper and lower ends of the operating rod 1 are also fixedly connected to blocks 14. The two groups of blocks 14 are respectively located at the two ends of the length direction of the slide rail 2. By providing the blocks 14, the upper and lower limit positions of the two sampling spoons can be limited while preventing them from slipping out.

[0034] The device is also provided with a preheating component, which uses a high-temperature preheating furnace. In order to ensure that the sampling spoon will not be damaged by thermal shock when it comes into contact with high-temperature liquid and to ensure the accuracy of sampling, the two sampling spoons need to be preheated, and the preheating temperature is set to 850°C to 900°C.

[0035] When using this device to sample electrolyte and molten aluminum, first adjust the positions of the first sampling spoon 6 and the second sampling spoon 7 in the height direction of the operating rod 1 according to the molten aluminum height and the electrolyte height in the process conditions, and then place the first sampling spoon 6 and the second sampling spoon 7 in the high-temperature preheating furnace for preheating. After preheating, the electrolyte shell is opened by the aluminum discharge cylinder, and the plate device is placed from top to bottom. It should be noted that at this time it is necessary to ensure that the cover plate 13 covers the upper end surface opening of the second sampling spoon 7. When the first sampling spoon 6 and the second sampling spoon 7 reach the corresponding electrolyte layer and molten aluminum layer, the upper electrolyte enters the first sampling spoon 6. By rotating the longitudinal rod 11, the rotating cross rod 12 and the cover plate are driven to rotate counterclockwise, thereby opening the upper end opening of the second sampling spoon 7, allowing the bottom molten aluminum to enter the second sampling spoon 7, thereby completing the sampling of the molten aluminum and the electrolyte.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
