[0033] Fluoride salts are generally added during the electrolysis of aluminum. Fluoride salts play a role in lowering the melting point, improving conductivity and inhibiting solubility during the electrolysis of aluminum, which helps to achieve efficient aluminum electrolysis production.
[0034] In the related art, the main ways to add fluoride salt to the electrolytic cell are: 1. Manually add it directly to the aluminum electrolytic cell, which requires workers to approach the electrolytic cell to manually open or close the feeding box. 2. Workers use fluoride salt feeding carts to add fluoride salt powder to the aluminum electrolytic cell. This method requires workers to remotely operate the fluoride salt feeding cart to open or close the feeding box. In this way, the above operation methods cannot ensure the alignment of the feed ports of the aluminum electrolytic cell and the feeding box, and it is easy to leak during the fluoride salt feeding process, which leads to the loss of fluoride salt materials flying.
[0035] To solve the above problems, please refer to Figure 1 and Figure 2 The present application provides an electrolytic cell device 1000. The electrolytic cell device 1000 includes an electrolytic cell 200 and a feeding device 100.
[0036] The electrolytic cell 200 may be an electrolytic cell 200 for electrolyzing aluminum, including a cell structure, a feed pipe 201, an electrolyte, a conductive system, an anode and a cathode, and other components or modules capable of realizing the electrolysis process.
[0037] The cell structure can be made of high temperature resistant and corrosion resistant materials, such as carbon materials or ceramic materials. The cell structure contains electrolyte, anode and cathode, etc. The electrolyte is a mixture used to conduct current and dissolve aluminum oxide. The anode is made of carbon material, such as coke or carbon block. The anode is oxidized during the electrolysis process and releases oxygen. The cathode is made of aluminum metal, which is the target product in the electrolysis process. Aluminum metal is precipitated on the cathode and is collected and extracted. The conductive system may include a current introduction device, a current distribution device and a current collection device, etc., which are used to provide current to the electrolytic cell 200 so that the electrolysis reaction occurs. The feed pipe body 201 is connected to the cell structure, and the feed pipe body 201 has a feed end face 2011 and a feed port 2012 opened on the feed end face 2011.
[0038] The feeding device 100 includes an overhead crane 10 , a material storage structure 20 , a feeding pipe body 30 and a pressure valve 40 .
[0039] The overhead crane 10 may be a device for moving and lifting goods in the field of industry, manufacturing or warehousing in the prior art, such as a bridge crane or a gantry crane, so as to achieve the function of crossing the working area, moving and positioning the goods. The overhead crane 10 includes a cross-over structure 11, a lifting structure 12 and a hook structure 13, wherein the cross-over structure 11 is connected to the lifting structure 12, and the lifting structure 12 is connected to the hook structure 13. The cross-over structure 11 is a mechanical structure for crossing the working area, such as a structure that can be moved in the horizontal direction on a track, a bridge or other supporting structure. The lifting structure 12 is a mechanical structure with a lifting function, such as a structure that can be moved in the vertical direction on a track, a bridge or other supporting structure, so that the overhead crane 10 can position and carry goods in the vertical direction. The material storage structure 20 is connected to the hook structure 13 of the overhead crane 10, so that the cross structure 11 and the lifting structure 12 of the overhead crane 10 drive the material storage structure 20 to move to synchronously drive the feeding pipe body 30 to move, so that the discharge port 31 and the feed port 2012 are docked, and the docking can be carried out by preset coordinate alignment or by worker operation.
[0040] The storage structure 20 is used to store fluoride salts, and the storage structure 20 is provided with a feeding port 20A connected to the inside, so that workers can replenish fluoride salts in the storage structure 20 through the feeding port 20A. The feeding tube body 30 is connected to the inside of the storage structure 20, and a discharge port 31 is provided at the bottom of the feeding tube body 30. The feeding tube body 30 and the storage structure 20 can be an integral structure, that is, the feeding tube body 30 and the storage structure 20 can be integrally formed by injection molding or the like, so as to further improve the connection stability between the feeding tube body 30 and the storage structure 20, and reduce the assembly steps for the two; of course, in other structural forms, the feeding tube body 30 and the storage structure 20 can be a split structure, and then connected by screws or buckles, so as to facilitate the replacement of the feeding tube body 30 and the storage structure 20. The embodiment of the present application is not limited to this.
[0041] The pressure valve 40 is connected to the feeding tube body 30, and the pressure valve 40 is used to open the discharge port 31 when subjected to an abutting external force. The pressure valve 40 includes a valve flap, which has an open state and a closed state, and blocks the discharge port 31 when in the closed state. When the overhead crane 10 drives the storage structure 20 to drive the feeding tube body 30 to move, so that the discharge port 31 and the feed port 2012 are docked, and the pressure valve 40 is abutted against the feed end face 2011, when the abutting external force reaches or exceeds the valve flap opening force of the pressure valve 40, the valve flap will open and switch to the open state, so that the fluoride salt in the feeding tube body 30 can enter the feed port 2012 after passing through the discharge port 31 and then be injected into the electrolytic cell 200. When the pressure valve 40 is separated from the feed end face 2011, that is, once the abutting external force is reduced to a set range, the valve flap will automatically close again to re-block the discharge port 31 to avoid the occurrence of material overflow.
[0042] Based on the feeding device 100 and the electrolytic cell equipment 1000 of the embodiment of the present application, when it is necessary to add fluoride salt to the electrolytic cell 200, the overhead crane 10 is controlled to drive the storage structure 20 to drive the feeding tube body 30 to move, so that the discharge port 31 and the feed port 2012 are docked, and the pressure valve 40 is abutted against the feed end face 2011, so that the pressure valve 40 automatically opens the discharge port 31 when subjected to the abutting external force, so that the fluoride salt in the storage structure 20 can pass through the discharge port 31 of the feeding tube body 30 and the feed port 2012 of the feed tube body 201 in sequence and then enter the electrolytic cell 200. When the feeding is completed, the overhead crane 10 is used to move the storage structure 20, so that the pressure valve 40 is disengaged from the feed end face 2011, so that the discharge port 31 is closed again, and the fluoride salt stops flowing out of the discharge port 31. In this way, there is no need to manually open or close the discharge port 31 during the fluoride salt feeding process, which has a high degree of automation, reduces the physical effort of workers, and effectively solves the potential safety hazard of being too close to the electrolytic cell 200 during manual feeding. At the same time, when the discharge port 31 is opened, it can be ensured that the discharge port 31 and the feed port 2012 are in a docking state, thereby reducing the leakage of materials during the fluoride salt feeding process in the electrolytic cell 200, reducing the waste caused by the flying fluoride salt and the harm to the workers, and adding fluoride salt raw materials in batches efficiently and safely in the electrolytic cell 200.
[0043] See also Figure 1 and Figure 2 Optionally, the feeding device 100 further includes a first magnetic member (not shown) and a second magnetic member (not shown), the first magnetic member is arranged on the side of the feeding tube body 30 facing the feeding end face 2011, the second magnetic member is arranged on the feeding end face 2011, and the first magnetic member and the second magnetic member are magnetically connected. The magnetic attraction between the first magnetic member and the second magnetic member can improve the accuracy of the docking between the discharge port 31 and the feeding port 2012, and the magnetic connection between the first magnetic member and the second magnetic member can also improve the tighter fit and the stability of the connection between the feeding tube body 30 and the feeding tube body 201, thereby further reducing the situation in which the fluoride salt flies due to the shaking of the feeding tube body 30 and the feeding tube body 201 during the fluoride salt delivery process.
[0044] See also Figure 1 and Figure 2In some structural forms, the storage structure 20 includes a warehouse body 21 and a hanging part 22, the warehouse body 21 is used to store fluoride salt, the feeding pipe body 30 is connected to the warehouse body 21, the hanging part 22 is connected to the outer wall of the warehouse body 21, and the overhead crane 10 is detachably connected to the hanging part 22. Among them, the warehouse body 21 and the hanging part 22 can be an integral structure, so as to ensure the overall structural strength of the storage structure 20. Of course, in other structural forms, the warehouse body 21 and the hanging part 22 can be a split structure, and then fixed by screw connection or clamping, so that the hanging part 22 can be repaired and replaced under long-term use, and the embodiment of the present application is not limited to this. The overhead crane 10 and the hanging part 22 can be connected by clamping, so that when the fluoride salt is added to the warehouse body 21, it can be removed from the hook of the overhead crane 10 through the hanging part 22 to facilitate the replenishment of fluoride salt and improve the operating efficiency.
[0045] Furthermore, at least two hooking parts 22 are provided, and the two hooking parts 22 are symmetrically arranged on opposite sides of the warehouse body 21. In this way, the hook of the overhead travelling vehicle 10 can simultaneously hook the hooking parts 22 located on opposite sides of the warehouse body 21, thereby improving the balance of the connection between the overhead travelling vehicle 10 and the material storage structure 20, and avoiding the problem of unbalanced unilateral support.
[0046] Optionally, an insulating layer (not shown) is provided at the connection between the hanging part 22 and the overhead travelling crane 10. It is understandable that the electrolytic cell 200 is provided with a conductive system to carry current. In order to reduce the current in the electrolytic cell 200 from flowing to the overhead travelling crane 10, an insulating layer is provided at the connection of the hanging part 22 to isolate the current from flowing to the overhead travelling crane 10, thereby improving the safety during the feeding process. Specifically, the hanging part 22 can be provided in a rod shape, and the insulating layer can be sleeved on the outer peripheral wall of the hanging part 22 along the length direction of the rod shape, so that the overhead travelling crane 10 can be insulated when in contact with multiple positions of the hanging part 22.
[0047] Furthermore, the insulating layer is made of nylon. Nylon is a thermoplastic polymer that has good electrical insulation properties, which means that it can effectively prevent the passage of current. At the same time, nylon is a wear-resistant material, which makes its use in the insulating layer very useful for protecting the hook portion 22 from external environment, friction or physical damage, so as to improve the wear resistance of the insulating layer.
[0048] See also Figure 1 and Figure 2In some structural forms, the chamber body 21 includes a first chamber body 211 and a second chamber body 212 connected to each other, the feeding tube body 30 is connected to the side of the second chamber body 212 away from the first chamber body 211, and the hanging part 22 is connected to the outer wall of the first chamber body 211. In the direction from the first chamber body 211 to the second chamber body 212, the cross section of the second chamber body 212 gradually decreases. In this way, the fluoride salt can flow to the feeding tube body 30 through the first chamber body 211 and the second chamber body 212 in sequence under the action of gravity. The second bin body 212 can be configured in a cone or funnel shape so that the cross-section of the second bin body 212 gradually decreases in the direction from the first bin body 211 to the second bin body 212, so that when the discharge port 31 and the feed port 2012 are connected and the pressure valve 40 is opened for discharge, the fluoride salt in the second bin body 212 can flow faster to the feeding tube body 30 and then flow out from the discharge port 31, thereby improving the efficiency of adding fluoride salt in the electrolytic cell 200.
[0049] Furthermore, the first storage body 211 is arranged in a rectangular block shape. Compared with the case where the storage structure 20 is in a funnel shape as a whole, the first storage body 211 is arranged in a rectangular block shape, which can carry more fluoride salts and reduce the frequency of replenishing fluoride salts in the storage structure 20 .
[0050] See also Figure 1 In some structural forms, the feeding device 100 further includes an isolating cylinder 50, which is connected to the feeding tube body 30 and is arranged at the outer peripheral side of the feeding tube body 30 in an interval ring. The isolating cylinder 50 can be fixed to the outer wall of the feeding tube body 30 by means of screws or buckles, so as to facilitate the maintenance and replacement of the isolating cylinder 50. The distance between the bottom opening of the isolating cylinder 50 and the material storage structure 20 is greater than the distance between the discharge port 31 of the feeding tube body 30 and the material storage structure 20. In this way, the isolation cylinder 50 surrounds the joint between the feeding tube body 30 and the feeding tube body 201 when the two are connected. Therefore, even if there is a gap between the feeding tube body 30 and the feeding tube body 201 and the fluoride salt leaks from the gap, the isolation cylinder 50 can block the fluoride salt leaking from the joint between the two, so as to further reduce the waste caused by the flying fluoride salt and the harm to the workers. The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if there are terms such as "upper", "lower", "left", "right" and the like indicating the orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, 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. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
