Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis production, and specifically relates to a device for retrieving detached anodes from electrolytic aluminum production. Background Technology

[0002] Currently, in the electrolytic aluminum production process, if the anode falls into the cell, the following specific treatment solutions are typically adopted:

[0003] 1. Manual Cleaning: This method involves manually removing anode debris from the tank using auxiliary tools such as shovels, grippers, and wire ropes. It is suitable for small amounts of debris or smaller tanks. However, it is time-consuming, labor-intensive, inefficient, and carries a high risk.

[0004] 2. Mechanical Cleaning: Using mechanical devices, such as tank removal tools, hooks, and suction cups, the anode debris is removed from the tank. This method is suitable for large quantities of debris or large tanks. However, it is extremely cumbersome and difficult to operate in the strong magnetic field environment of an electrolysis workshop.

[0005] 3. Tank Emptying: Drain the electrolyte from the tank, and then remove the anode debris from the tank by tilting or disassembling it. This method is suitable for situations where other cleaning methods are not feasible. However, this treatment method may cause significant economic losses to the production process and have a serious adverse effect on the lifespan of the electrolytic cell. Utility Model Content

[0006] The purpose of this invention is to provide a device for retrieving detached electrolytic aluminum anodes to solve the above-mentioned problems.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A device for retrieving detached electrolytic aluminum anodes includes a trolley mechanism and a clamping mechanism placed on the trolley mechanism. The clamping mechanism includes two parallel scissor structures. Each scissor structure includes an upper left scissor plate, an upper right scissor plate, a lower left clamping plate, and a lower right clamping plate. One end of the upper left and upper right scissor plates is cross-connected, and the other end of the upper left and upper right scissor plates is cross-connected to one end of the lower left and lower right clamping plates, respectively. The free ends of the lower left and lower right clamping plates are bent downwards, and the middle parts of the lower left and lower right clamping plates are cross-connected. A double-headed connecting rod is provided at each corresponding cross-connection position of the two scissor structures for rotatable connection. A clamping plate I is provided between the two lower left clamping plates, and a clamping plate II is provided between the two lower right clamping plates. Clamping plates I and II are parallel. Hooks are sleeved on the double-headed connecting rods provided on the connecting ends of the upper left and upper right scissor plates.

[0009] To further realize this utility model, both the lower left clamping plate and the lower right clamping plate include a slanted plate, a horizontal plate, and a downwardly bent clamping plate. The slanted plate and the horizontal plate are an integral structure, and the included angle between the slanted plate and the horizontal plate is an obtuse angle. The horizontal plate and the clamping plate are perpendicular to each other. The upper end of the slanted plate is connected to the upper left scissor plate. A cross connection position is provided at the junction of the slanted plate and the horizontal plate for passing through a double-headed connecting rod. Clamping plate I and clamping plate II are respectively provided between the two clamping plates of the lower left clamping plate and the lower right clamping plate. Clamping plate I and clamping plate II are respectively provided on the side wall of the clamping plates of the lower left clamping plate and the lower right clamping plate facing each other.

[0010] To further realize this utility model, a number of locking teeth are evenly arranged on the facing surfaces of clamping plate I and clamping plate II.

[0011] To further realize this utility model, pull plates are respectively provided between the two upper left scissor plates and between the two upper right scissor plates.

[0012] To further realize this utility model, the trolley mechanism includes a trolley plate, wheels, and a handle. Protective plates are provided around the trolley plate, and a support frame is provided in the center of the trolley plate. The support frame has an "H" shaped structure, and the height of the crossbar of the support frame is adapted to the distance from the crossbar to the bottom surface of the clamping plate. A baffle is provided on one side of the vertical rod of the support frame. The protective plates can prevent the clamping mechanism from sliding outwards during transportation; the support frame can support the clamping mechanism during transportation; the crossbar can support the lower left and lower right clamping plates, preventing excessive lowering of the middle section from causing tipping or breakage; the baffle can prevent excessive pushing during placement from causing it to tip over from that side.

[0013] To further realize this utility model, a connecting plate is provided between the handle and the vehicle plate, and a wheel is also provided under the connecting plate.

[0014] To further realize this utility model, the upper left scissor plate, the upper right scissor plate, the lower left clamping plate, and the lower right clamping plate are all made of 30mm thick steel plates.

[0015] To further realize this utility model, the distance between the two scissor structures is 350mm, and the distance between clamping plate I and clamping plate II is 880mm.

[0016] The advantages of this utility model compared to the prior art are as follows:

[0017] 1. Clamping Stability: The clamping mechanism adopts a scissor structure design. When the hook is pulled upward by a large lifting tool, the angle between the scissor structure and the central axis continuously decreases, thereby reducing the gap between clamping plates I and II. This allows for a firm grip on the anode carbon block. The higher the pull, the greater the gravitational force on the scissor structure, and the greater the clamping force of clamping plates I and II, ensuring a tight grip on the anode carbon block and improving clamping stability. This allows for successful retrieval of the carbon block and prevents it from falling out. By incorporating clamping plates I and II and locking teeth, surface friction is increased, enhancing safety and reliability during operation.

[0018] 2. Protecting the electrolytic cell: The clamping mechanism is designed to prevent objects that are difficult to control or grasp, such as hooks, shovels, and wire ropes, from entering the electrolytic cell, thereby reducing damage and corrosion to the electrolytic cell.

[0019] 3. Improved work efficiency: Using a clamping mechanism to hold the anode carbon block allows for faster replacement or maintenance, improving work efficiency. The clamping mechanism is simple and convenient to operate, enabling quick clamping and release of the anode carbon block, reducing the time and effort required for maintenance and replacement.

[0020] 4. Safety: Stable clamping by the clamping mechanism reduces the occurrence of accidents and ensures the safety of operators. The design of the clamping mechanism can also reduce the possibility of misoperation or accidental triggering, further improving safety. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-4 As shown, an electrolytic aluminum anode detachment retrieval device includes a trolley mechanism 30 and a clamping mechanism 40 placed on the trolley mechanism 30. The clamping mechanism 40 includes two parallel scissor structures with a distance of 350mm between them. Each scissor structure includes an upper left scissor plate 1, an upper right scissor plate 2, a lower left clamping plate 3, and a lower right clamping plate 4. One end of the upper left scissor plate 1 and the upper right scissor plate 2 are cross-connected, and the other end of the upper left scissor plate 1 and the upper right scissor plate 2 are cross-connected to one end of the lower left clamping plate 3 and the lower right clamping plate 4, respectively. The free ends of the lower left clamping plate 3 and the lower right clamping plate 4 are bent downwards. The lower clamping plates 4 are cross-connected in the middle. Each corresponding cross-connection position in the two scissor structures is provided with a double-headed connecting rod 5 for rotational connection. A clamping plate I 6 is provided between the two lower left clamping plates 3, and a clamping plate II 7 is provided between the two lower right clamping plates 4. The clamping plates I 6 and II 7 are parallel, and the distance between the clamping plates I 6 and II 7 is 880mm. A hook 8 is sleeved on the double-headed connecting rod 5 provided on the connecting end of the upper left scissor plate 1 and the upper right scissor plate 2. Pull plates 22 are provided between the two upper left scissor plates 1 and the two upper right scissor plates 2 respectively. The upper left scissor plate 1, the upper right scissor plate 2, the lower left clamping plate 3 and the lower right clamping plate 4 are all made of 30mm thick steel plate.

[0028] The lower left clamping plate 3 and the lower right clamping plate 4 each include a diagonal plate 9, a horizontal plate 10, and a downwardly bent clamping plate 11. The diagonal plate 9 and the horizontal plate 10 are an integral structure. The included angle between the diagonal plate 9 and the horizontal plate 10 is an obtuse angle. The horizontal plate 10 and the clamping plate 11 are perpendicular to each other. The upper end of the diagonal plate 9 is connected to the upper left scissor plate 1. A cross connection position is set at the junction of the diagonal plate 9 and the horizontal plate 10 for passing through the double-headed connecting rod 5. Clamping plate I 6 and clamping plate II 7 are respectively set between the two clamping plates 11 of the lower left clamping plate 3 and the lower right clamping plate 4. Clamping plate I 6 and clamping plate II 7 are respectively set on the side wall of the clamping plates 11 of the lower left clamping plate 3 and the lower right clamping plate 4 facing each other. Several clamping teeth 12 are evenly arranged on the facing surfaces of clamping plate I 6 and clamping plate II 7.

[0029] The trolley mechanism 30 includes a trolley plate 13, wheels 14, and a handle 15. The trolley plate 13 is surrounded by guard plates 16, and a support frame 17 is set in the center of the trolley plate 13. The support frame 17 has an "H" shaped structure. The height of the crossbar 18 of the support frame 17 is adapted to the distance from the cross plate 10 to the bottom surface of the clamping plate 11. A baffle 20 is set on one side of the vertical rod 19 of the support frame 17. A connecting plate 21 is set between the handle 15 and the trolley plate 13. Wheels 14 are also set under the connecting plate 21.

[0030] Before commencing operations, the anode detachment retrieval device must first be dried to ensure its surface is dry. Next, the dried anode detachment retrieval device is moved to the work area, a process that can be accomplished using a trolley. Then, a dedicated overhead crane operator connects the hook 8 to the crane hook, lifting the clamping mechanism 40 to the work point.

[0031] After the crane operator positions the clamping mechanism 40, they perform a hook-lowering operation, ensuring that clamping plates I6 and II7 contact both sides of the anode detachment. After confirming reliable contact between clamping plates I6 and II7 and the detached anode sides, the crane operator lifts the detached material onto the transport vehicle. This process ensures the safe and efficient transport of the anode detachment, guaranteeing the continuity and efficiency of the operation. During the operation, the crane operator and electrolysis personnel work closely together, strictly adhering to operating procedures to ensure operational safety and equipment integrity.

[0032] After all the fallen objects have been retrieved, the crane operator will place the clamping mechanism 40 back onto the platform 13 and transport it to its designated location. This step ensures the orderly return of the device to its proper place while maintaining the cleanliness and safety of the work area.
