Description

Technical Field

[0001] The utility model relates to a loading and unloading tool for soluble nickel anodes, belonging to the technical field of nickel electrolysis equipment. Background Art

[0002] Soluble anode nickel electrolysis is the main process and production method for the hydrometallurgical refining of non-ferrous metal nickel. In large-scale electrolytic nickel production, hundreds of electrolytic cells are configured in the electrolysis workshop for electrified production. Considering the characteristics of high-sulfur nickel anodes, to improve the electrolysis production efficiency, usually one anode cycle corresponds to two cathode cycles. After the electrolytic nickel is taken out of the tank in the first cathode cycle, in order to achieve the purpose of reducing the resistance and improving the electrical efficiency in the second half cycle of the soluble high-sulfur anode, the anode needs to be taken out of the tank, hoisted above the adjacent electrolytic cell to the anode slime pool to remove the anode slime and then loaded into the tank for production; after the electrolytic nickel is taken out of the tank in the second cathode cycle, the anode has dissolved and thinned into a stub anode, and the stub anode needs to be taken out of the tank again, hoisted above the adjacent electrolytic cell to the stub anode area for treatment. When the nickel anode (stub anode) is hoisted out of the tank and passes through the adjacent electrified production electrolytic cell using a conventional hanging bracket, the anode liquid and anode slime attached to and carried by the nickel anode (stub anode) will fall into the cathode chamber of the adjacent electrified production electrolytic cell, polluting the cathode liquid in the cathode chamber of the adjacent electrolytic cell, thereby reducing the quality of electrolytic nickel in the adjacent electrolytic cell and seriously affecting the grade rate and economic benefits of electrolytic nickel products. Therefore, in order to solve the problem that the anode liquid and anode slime attached to and carried by the nickel anode (stub anode) fall into the cathode chamber of the adjacent electrified production electrolytic cell when the nickel anode (stub anode) is hoisted out of the tank and passes through the adjacent electrified production electrolytic cell, improve the quality and grade rate of electrolytic nickel production, and improve the economic benefits of nickel electrolysis production, it is necessary to design a loading and unloading tool for soluble nickel anodes. Content of the Utility Model

[0003] Aiming at the problems existing in the above background art, the utility model optimizes and iteratively upgrades the traditional hanging bracket, and provides a loading and unloading tool for soluble nickel anodes with a simple structure and convenient use. This loading and unloading tool solves the problem that the anode liquid and anode slime attached to and carried by the nickel anode (stub anode) fall into the adjacent electrolytic cell to pollute the cathode liquid during the process of hoisting the nickel anode (stub anode) out of the tank and passing through a large number of adjacent electrified production electrolytic cells, improves the quality of electrolytic nickel production, and significantly enhances the economic benefits of nickel electrolysis production.

[0004] To achieve the above object, the technical solution of the utility model is as follows:

[0005] A loading and unloading tool for soluble nickel anodes includes a hanging bracket. A hanging bracket hook is arranged at the top of the hanging bracket, and a hanging chain is fixedly connected to the hanging bracket hook; an anode hook is arranged at the bottom of the hanging bracket, and an anode rod fixed to the nickel anode is hung on the anode hook; a liquid receiving tray hook is arranged on the side of the hanging bracket, a suspension strap is hung on the liquid receiving tray hook, and the other end of the suspension strap is connected to a liquid receiving tray.

[0006] The utility model has the following advantages:

[0007] 1. The ordinary hanger has been optimized and improved, upgraded iteratively, with a simple structure, uniform force, safety and reliability, and easy use. It improves the electrolytic nickel production environment and is an effective tool for the installation of soluble nickel anodes;

[0008] 2. When the nickel anode is unloaded, the overhead crane lifts half of the nickel anode (residual anode) out of the tank each time through the lifting chain and the hanger. The hanger is hung on the liquid receiving tray placed next to it and then lifted vertically. When the nickel anode (residual anode) is hoisted out of the tank and passes through a large number of adjacent energized production electrolytic cells, it receives the anode liquid and anode mud attached to the nickel anode (residual anode), preventing it from falling into the adjacent electrolytic cells and contaminating the cathode liquid, thereby improving the quality of electrolytic nickel production.

[0013] The utility model is further explained below in conjunction with the accompanying drawings.

[0014] like Figures 1-3 As shown, a tool for loading soluble nickel anodes includes a hanger 1, a hanger hook 5 is arranged on the top of the hanger 1, and a hanging chain 4 is fixedly connected to the hanger hook 5; an anode hook 8 is arranged at the bottom of the hanger 1, and an anode rod 9 fixed to the nickel anode 2 is hung on the anode hook 8; a liquid receiving pan hook 6 is arranged on the side of the hanger 1, and a sling 7 is hung on the liquid receiving pan hook 6, and the other end of the sling 7 is connected to the liquid receiving pan 3.

[0015] The length of the hanger 1 is determined in combination with the size of the electrolytic cell, which is usually 3 / 5 of the inner diameter of the electrolytic cell. The number of anode hooks 8 is the number of nickel anodes (residual electrodes) in half a cell. One nickel anode (residual electrode) is hoisted out for half a cell, and two nickel anodes (residual electrodes) are hoisted out for one cell. The width of the hanger 1 is determined in combination with the size of the soluble nickel anode, and the width of the hanger 1 is the width of two nickel anodes 2.

[0016] The liquid receiving tray 3 is made of rubber-lined steel material that is resistant to corrosion by acidic electrolyte, which is economical and practical; its length is 1.1-1.2 times the length of the hanger 1, and its width is 1.4-1.5 times the width of the hanger 1. The edges of the liquid receiving tray 3 are tilted upward, and the height of the tray is 0.24-0.3m. The purpose is to receive the anode liquid and anode mud attached to the nickel anode (residual electrode) to prevent it from falling into the electrolytic cell in power production during the lifting process, and contaminating the cathode liquid in the cathode chamber of the adjacent electrolytic cell.

[0017] The hanger hook 5 and the liquid receiving tray hook 6 are symmetrically distributed at the 3 / 5-4 / 5 position in the length direction of the hanger, so as to ensure that the hanger is evenly stressed and improve the stability of the lifting.

[0018] The working process of the utility model is as follows:

[0019] 1. When the nickel anode (residual anode) is ready to be loaded, the other ends of the four slings bolted on the liquid receiving tray 3 are hung on the hooks 6 of the liquid receiving tray respectively, and the lifting chain 4 is hung on the hanger 1, and then the lifting ring of the lifting chain 4 is hung on the hook head of the overhead crane, and the loading tool of the soluble nickel anode is moved to the side of the anode electrolytic cell to be loaded.

[0020] 2. Remove the strap from the liquid collecting pan hook 6 and put down the liquid collecting pan 3.

[0021] 3. Operate the overhead crane to move the hanger above the nickel anode (residual electrode) to be loaded, lower the hanger 1 to hang the anode hook 8 on the anode rod 9, operate the overhead crane to lift the nickel anode (residual electrode) out of the tank to a certain height through the hanger, and then move it horizontally to the liquid receiving tray 3.

[0022] 4. Hang the sling 7 bolted on the liquid receiving tray 3 on the liquid receiving tray hook 6 to mount the liquid receiving tray 3; operate the overhead crane to vertically lift the soluble nickel anode discharging tool to a certain height, and then move it horizontally to the specified position. During the process of the nickel anode (residual anode) being hoisted out of the tank and passing through a large number of adjacent energized production electrolytic cells, the anode liquid and anode mud attached to the nickel anode (residual anode) are taken over, preventing it from falling into the adjacent electrolytic cells and contaminating the cathode liquid.

[0023] Repeat the above specific steps to repeatedly install the nickel anode (residual electrode).
