Abstract

[0002] In the hydrometallurgical cobalt chloride solution extraction process, equipment such as mixing and clarifying tanks, centrifugal extractors, and extraction towers are commonly used for large-scale continuous extraction and the mixing and separation of two phases. However, in actual production, the cobalt solution after separation still contains a small amount of organic phase. Since commonly used extractants have a certain degree of hydrophilicity, in addition to large-sized organic phases that are not clarified in time, a certain amount of organic phase will exist in the cobalt chloride solution in a stable emulsion or even dissolved state. If the organic phase entrained in the aqueous phase of the cobalt chloride solution is not removed in time, it will not only increase extractant consumption but also adversely affect downstream processes, thereby reducing the quality of the metallurgical product. Summary of the Invention

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0019] This utility model discloses a cobalt chloride solution activated carbon pre-removal organic phase device. The device mainly includes a solution tank 1, a grid plate 2, a stirring device 3, activated carbon 4, a heating coil 5, a supporting screen 6, and a bag filter 7. The bottom of the solution tank 1 is conical, and the supporting screen 6 for supporting the activated carbon 4 is installed at the bottom of the solution tank 1. The activated carbon 4 is filled at the bottom of the solution tank 1. The activated carbon 4 is 8-50 mesh irregular granular coconut shell granular activated carbon with a moisture content ≤10% and a new standard iodine value ≥900. The grid plate 2 is installed horizontally in the middle of the solution tank 1 to slow down the downward flow rate of the liquid and reduce the upward dispersion rate of the granular activated carbon. The stirring device 3 is horizontally installed on the side wall of the solution tank 1. The stirring device 3 is located between the grid plate 2 and the activated carbon 4 filling layer. The heating coil 5 is installed on the conical curved surface at the bottom of the solution tank 1. The solution tank 1 is provided with an inlet pipe 11 at the top and an outlet pipe 12 at the bottom. The bag filter 7 is installed on the outlet pipe 12 to prevent activated carbon that has passed through the screen from mixing into the solution, thus playing a role in filtering and intercepting.
[0020] A three-way valve 13 is installed on the liquid outlet pipe 12. The three-way valve 13 is connected to the top of the solution tank 1 by a return pipe 14. A drive pump is installed on the return pipe 14.
[0021] The heating coil 5 is equipped with a steam return valve 50 and a steam heating valve 51. A temperature detection device 52 is installed on the side wall of the solution tank 1. The steam return valve 50, the steam heating valve 51 and the temperature detection device 52 are all connected to the controller.
[0022] The stirring device 3 includes a stirring motor 31, a stirring shaft 32, a sealing seat 33, and a stirring paddle 34. The stirring shaft 32 is horizontally mounted on the side wall of the solution tank 1 through the sealing seat 33. The stirring motor 31 is mounted on the sealing seat 33 and is connected to the stirring shaft 32 in a driving connection. The stirring paddle 34 is evenly mounted on the stirring shaft 32.
[0023] The grid bars of the grid plate 2 are arranged along the stirring shaft 32 of the stirring device 3, and the spacing between the grid bars is larger in the middle and smaller on both sides.
[0024] The heating coil 5 is covered with an insulation cover to prevent heat from diffusing outward.
[0025] Work process:
[0026] The cobalt chloride solution to be treated is pumped into this device. Based on experimental data, activated carbon exhibits optimal adsorption capacity for organic phases between 30-40℃. Therefore, considering the initial temperature of the feed solution, a temperature interlock value of 35℃ is recommended. When the temperature is below 30℃, steam heating valve 51 and steam return valve 50 automatically open to heat the liquid in the device. When the temperature is above 40℃, steam heating valve 51 and steam return valve 50 automatically close, resuming normal production.
[0027] As production proceeds, the stirring device 3 is started; the stirring device 3 is kept in operation at all times unless production stops.
[0028] When the organic phase content in the cobalt chloride solution fails to meet the standard as detected by the sampling valve, the substandard solution is returned to the system for further processing via the three-way valve 13.
[0029] If, after a period of use, the organic phase content in the cobalt chloride solution fails to decrease as determined by laboratory tests, it indicates that the activated carbon has become saturated and ineffective. In this case, it is necessary to close the electric inlet valve, disassemble the bottom activated carbon discharge flange, and replace the activated carbon with new one.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
