Description

Technical Field

[0001] The utility model relates to the technical field of high-purity aluminum production, in particular to an auxiliary device for loading and unloading graphite rods. Background Technique

[0002] At present, although the three-layer liquid aluminum electrolytic refining technology for purifying refined aluminum (AL≥99.998%) is only owned by a few countries such as China, Japan, Germany, France, the United States, and Norway in the world, the three-layer liquid aluminum electrolytic refining method generally has disadvantages such as large series investment, high energy consumption, high maintenance cost, and inability to operate continuously.

[0003] Due to the huge energy consumption and low market benefits of the three-layer liquid electrolytic refining method, more and more efforts are being invested in the research and production of the segregation method. The segregation method is also called the solidification purification method. The segregation method is a method of extracting high-purity aluminum by utilizing the compositional segregation phenomenon generated during the solidification of alloys. The solid aluminum part solidified during the cooling and solidification process of the aluminum melt containing trace impurity elements has a lower impurity content than the impurity content in the melt.

[0004] The lower end of the graphite rod of the segregation furnace is threadedly connected to the graphite disk. During the process of purifying aluminum liquid in the segregation furnace, the graphite disk is always in the molten aluminum liquid, and the graphite rod will continuously repeat being lifted out of and inserted into the aluminum liquid according to the technological process.

[0005] In this way, when the graphite rod is severely oxidized while the graphite disk can still be used, the graphite rod needs to be disassembled. However, the graphite rod is large in weight and volume, and it is inconvenient for manual loading and unloading. Content of the Utility Model

[0006] In view of this, the utility model provides an auxiliary device for loading and unloading graphite rods, and the main purpose is to improve the convenience of manual loading and unloading of graphite rods.

[0007] To achieve the above purpose, the utility model mainly provides the following technical solutions:

[0008] The utility model provides an auxiliary device for loading and unloading graphite rods, and the device includes: a lever and a chain;

[0009] One end of the lever is fixedly connected to a sprocket, and the length direction of the lever coincides with the diameter direction of the sprocket;

[0010] One end of the chain is connected to one end side of the lever;

[0011] Wherein, the chain and the sprocket are coplanar.

[0012] The purpose of the utility model and the solution of its technical problems can be further realized by adopting the following technical measures.

[0013] Optionally, the length of the chain is greater than 1.1 times the radial circumference of the graphite rod.

[0014] Optionally, a plurality of notches are axially arranged on the other end side of the lever.

[0015] Optionally, the lever is made of a steel pipe.

[0016] By means of the above technical solutions, the present utility model has at least the following advantages:

[0017] A hydraulic cylinder is installed in the upper space of the workshop building. The piston rod of the hydraulic cylinder is connected to a large nut, and the large nut is connected to the upper end of the graphite rod, so that the hydraulic cylinder can drive the graphite rod to move up and down.

[0018] When assembling or disassembling the graphite rod, the graphite disk is fixed on the ground of the workshop building, and the chain of the auxiliary device is manually wound around the graphite rod, so that the other end of the chain passes through the space between the graphite rod and the sprocket, and the sprocket is close to and meshes with the chain. Then, the other end of the lever is pushed in the opposite direction of the chain winding direction, so that the winding and tensioning degree of the chain on the radial section of the graphite rod becomes tighter and tighter;

[0019] On the basis of the chain being tightened, by continuously pushing the other end of the lever, a large rotational torque can be applied to the graphite rod, so that the graphite rod can rotate relative to the graphite disk, achieving the purpose of assembling or disassembling the graphite rod.

[0020] By using this device, the difficulty of manual loading and unloading of the graphite rod is reduced, and the work efficiency is improved. Description of the Drawings

[0024] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features, and effects according to the present utility model application. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0025] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] As Figure 1 and Figure 2 shown, an auxiliary device for loading and unloading graphite rods provided by an embodiment of the present utility model includes: a lever 1 and a chain 2;

[0027] One end of the lever 1 is fixedly connected to a sprocket 3, and the length direction of the lever 1 coincides with the diameter direction of the sprocket 3;

[0028] One end of the chain 2 is connected to one end side of the lever 1;

[0029] Wherein, the chain 2 and the sprocket 3 are coplanar.

[0030] The working process of an auxiliary device for loading and unloading graphite rods is as follows:

[0031] A hydraulic cylinder is installed in the upper space of the workshop building. The piston rod of the hydraulic cylinder is connected to a large nut, and the large nut is connected to the upper end of the graphite rod 5, so that the hydraulic cylinder can drive the graphite rod 5 to move up and down.

[0032] When assembling or disassembling the graphite rod 5, fix the graphite disk 6 on the ground of the workshop building, manually wind the chain 2 of the present auxiliary device around the graphite rod 5, so that the other end of the chain 2 passes through the space between the graphite rod 5 and the sprocket 3, and make the sprocket 3 approach and engage with the chain 2, and then push the other end of the lever 1 in the opposite direction of the winding direction of the chain 2. The sprocket 3 continues to drive the chain 2 to be tensioned and stretched along its original winding direction. In this way, the winding and tensioning degree of the chain 2 on the radial cross-section of the graphite rod 5 becomes tighter and tighter. Among them, Figure 2 the arrow direction in the figure is the winding direction of the chain 2;

[0033] On the basis of the chain 2 being tensioned, continue to push the other end of the lever 1, and a large rotational torque can be applied to the graphite rod 5, so that the graphite rod 5 can rotate relative to the graphite disk 6, achieving the purpose of assembling or disassembling the graphite rod 5.

[0034] When the graphite rod 5 and the graphite disk 6 are assembled, the hydraulic cylinder hoists the graphite rod 5 and the graphite disk 6, and then installs them in the refined aluminum segregation furnace; when the graphite rod 5 needs to be disassembled, operate in the reverse direction.

[0035] In the technical solution of the present utility model, by using this device, the difficulty of manually loading and unloading the graphite rod 5 is reduced, the work efficiency is improved, and thus the convenience of loading and unloading the graphite rod 5 is improved.

[0036] Specifically, when using this device, it is only necessary to determine in advance the disassembly direction or assembly direction of the graphite rod 5, so that the pushing direction at the other end of the lever 1 is consistent with the rotation (disassembly or assembly) direction of the graphite rod 5 itself, and the purpose of disassembling or assembling the graphite rod 5 can be achieved.

[0037] Specifically, in the structure of the refined aluminum segregation furnace, the lower end of the graphite rod 5 is threadedly connected to the central hole of the graphite disk 6.

[0038] In the specific embodiment, the length of the chain 2 is greater than 1.1 times the radial circumference of the graphite rod 5.

[0039] In this embodiment, specifically, during the process of the chain 2 being tensioned and fitting onto the graphite rod 5, the overlapping part of the chain 2 should not be excessive. Otherwise, the friction between the overlapping parts of the chain 2 is relatively large, which is not conducive to the relative movement of the overlapping part of the chain 2 and is not conducive to the continuous tensioning of the chain 2 along the winding direction.

[0040] In the specific embodiment, a plurality of notches 4 are axially arranged on the other end side of the lever 1.

[0041] In this embodiment, specifically, the notches 4 and the chain 2 are located on the opposite sides of the lever 1. When the operator holds the lever 1, the fingers can be inserted into the plurality of notches 4 to increase the stability of the grip.

[0042] In the specific embodiment, the lever 1 is made of a steel pipe.

[0043] In this embodiment, specifically, the lever 1 is made of a steel pipe, and the steel pipe is hollow, which reduces the overall weight of this device and is convenient for carrying.

[0044] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
