Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, and in particular to a cobalt acetate solution impurity removal reaction tank. Background Technology

[0002] Cobalt acetate solution is widely used in the preparation of lithium battery cathode materials and catalysts. Its purity directly affects the performance of downstream products, making impurity removal a critical step in the production process. Currently, commonly used cobalt acetate solution impurity removal devices in the industry require a powdered impurity remover addition and mixing process. The powdered impurity remover falls naturally from a simple outlet at the bottom of the silo and directly enters a reaction tank containing the cobalt acetate solution. The impurity remover is then mixed with the solution using a single stirring blade within the reaction tank.

[0003] A Chinese patent (CN216338008U) discloses an electrolytic nickel purification and impurity removal reaction tank. The tank includes a cylindrical tank body, a tank cover, and a flow guiding device. A bottom air duct is located at the lower end of the cylindrical tank body, and an inlet and outlet are located on the side of the tank body. The tank cover seals the upper opening of the cylindrical tank body, and the top of the cover has a vent, a chlorine inlet pipe, a reagent inlet, and a detection port. The chlorine inlet pipe extends to a depth of less than two-thirds of the cylindrical tank body, and a pH / ORP meter is installed at the detection port. The flow guiding device includes a flow guiding cylinder, which is vertically installed within the cylindrical tank body, and its upper end is connected to the outlet. Automatic regulating valves are installed on the bottom air duct, vent, inlet, outlet, chlorine inlet pipe, and reagent inlet. This invention enables efficient impurity removal in high-flow-rate, high-impurity systems, yielding pure electrolytic cathode liquid.

[0004] In the powdered impurity remover feeding process, traditional equipment often uses cylindrical storage tanks with a lack of effective stirring components. This makes the powder prone to accumulating due to its inherent properties, affecting production continuity and potentially causing localized overfeeding and fluctuations in the impurity remover concentration in the solution. Furthermore, current feeding control methods rely heavily on simple valve adjustments, failing to achieve periodic stability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a cobalt acetate solution impurity removal reaction tank, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a cobalt acetate solution impurity removal reaction tank, comprising a cylindrical tank body, a load-bearing support fixedly connected to the upper end of the cylindrical tank body, a batching tank fixedly connected to the upper end of the load-bearing support, a motor fixedly connected to the upper end of the batching tank, a linkage shaft installed at the output end of the motor, a driven shaft fixedly connected to the lower end of the linkage shaft, a powder stirring fan blade fixedly connected to the outer end of the linkage shaft, a liquid stirring fan blade fixedly connected to the outer end of the driven shaft, a discharge cylinder fixedly connected to the lower end of the batching tank, a bottom plate fixedly connected to the lower end of the discharge cylinder, discharge rings symmetrically fixedly connected to the left and right sides of the lower end of the bottom plate, and a shaped linkage shielding plate fixedly connected to the outer end of the driven shaft, the shaped linkage shielding plate being located below the bottom plate and fitting together with the discharge rings.

[0007] As a further technical solution of this utility model, the powder stirring fan blade is located inside the batching storage tank, and the liquid stirring fan blade is located inside the cylindrical tank.

[0008] As a further technical solution of this utility model, the batching tank stores a number of powder ingredients, and the cylindrical tank is filled with a number of solutions.

[0009] As a further technical solution of this utility model, a fixing ring is fixedly connected to the upper side of the inner wall of the cylindrical groove, and multiple springs are fixedly connected to the upper end of the fixing ring.

[0010] As a further technical solution of this utility model, multiple springs are arranged in a ring at equal intervals, and a screen is fixedly connected to the upper end of the multiple springs.

[0011] As a further technical solution of this utility model, the inner wall of the screen is fixedly connected with a plurality of protruding inner blocks, and the upper side of the outer end of the driven rotating shaft is fixedly connected with an extension rod.

[0012] As a further technical solution of this utility model, the end of the extended stop rod away from the driven rotating shaft and the multiple protruding inner blocks are in sequential contact, and the screen is located between the discharge end of the discharge cylinder and the feed end of the cylindrical trough.

[0013] This invention provides a cobalt acetate solution impurity removal reaction tank, which has the following advantages compared with the prior art: This design presents a cobalt acetate solution impurity removal reaction tank. First, a linkage shaft drives a stirring fan to agitate the powder in the mixing tank, effectively preventing the accumulation of the powder impurity remover. Combined with a specially shaped linkage baffle plate and the periodic opening and closing of the discharge ring, the quantitative drop of powder is precisely controlled. The driven shaft drives an extended push rod that engages with the protruding inner block of the screen, and the spring's rebound action causes the screen to vibrate continuously, further dispersing and sieving the falling powder. Simultaneously, the driven shaft synchronously drives the stirring fan to agitate the liquid within the cylindrical tank, ensuring thorough mixing of the dispersed powder with the cobalt acetate solution and preventing excessively high local concentrations. The entire device relies solely on a single motor power source, eliminating the need for additional vibration and stirring equipment, thus balancing economy and practicality, and stably adapting to continuous impurity removal production needs.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a technical solution for a cobalt acetate solution impurity removal reaction tank: it includes a cylindrical tank 1, a load-bearing bracket 2 fixedly connected to the upper end of the cylindrical tank 1, a batching storage tank 3 fixedly connected to the upper end of the load-bearing bracket 2, a motor 4 fixedly connected to the upper end of the batching storage tank 3, a linkage shaft 5 installed at the output end of the motor 4, a driven shaft 6 fixedly connected to the lower end of the linkage shaft 5, a powder stirring fan blade 7 fixedly connected to the outer end of the linkage shaft 5, a liquid stirring fan blade 8 fixedly connected to the outer end of the driven shaft 6, a discharge cylinder 9 fixedly connected to the lower end of the batching storage tank 3, a bottom plate 15 fixedly connected to the lower end of the discharge cylinder 9, and discharge rings 16 symmetrically fixedly connected to the left and right sides of the lower end of the bottom plate 15. A special-shaped linkage shielding plate 17 is fixedly connected to the outer end of the driven shaft 6, and the special-shaped linkage shielding plate 17 is located below the bottom plate 15 and fits together with the discharge rings 16.

[0018] Please see Figures 2-4 The powder stirring blade 7 is located inside the batching storage tank 3, and the liquid stirring blade 8 is located inside the cylindrical tank 1. The batching storage tank 3 stores a certain amount of powder ingredients, and the cylindrical tank 1 is filled with a certain amount of solution. A fixing ring 13 is fixedly connected to the upper side of the inner wall of the cylindrical tank 1. Multiple springs 14 are fixedly connected to the upper end of the fixing ring 13. The multiple springs 14 are arranged in a ring at equal intervals. A screen 10 is fixedly connected to the upper end of the multiple springs 14. Multiple protruding inner blocks 11 are fixedly connected to the inner wall of the screen 10. An extension rod 12 is fixedly connected to the upper side of the outer end of the driven rotating shaft 6. The end of the extension rod 12 away from the driven rotating shaft 6 contacts the multiple protruding inner blocks 11 in sequence. The screen 10 is located between the discharge end of the discharge cylinder 9 and the feed end of the cylindrical tank 1.

[0019] The working principle of this utility model is as follows: First, after the motor 4 starts, it drives the linkage shaft 5 to rotate. The linkage shaft 5 synchronously drives the driven shaft 6 to rotate. The powder stirring fan blade 7 at the outer end of the linkage shaft 5 rotates with it in the batching storage tank 3, stirring the stored powder impurity remover to avoid powder accumulation and bridging, ensuring smooth material discharge. When the driven shaft 6 rotates, the irregular linkage shielding plate 17 at its outer end rotates synchronously. Because the irregular linkage shielding plate 17 is in contact with the discharge ring 16 below the bottom plate 15, the discharge channel of the discharge ring 16 will periodically open and close during the rotation, realizing the quantitative drop of the powder impurity remover. At the same time, the extended abutment rod 12 on the upper side of the outer end of the driven shaft 6 rotates with the shaft. The end of the extended abutment rod 12 away from the driven shaft 6 will contact multiple protruding inner blocks 11 on the inner wall of the screen 10 in sequence. When the extended abutment rod 12 abuts against the protruding inner blocks 11, the screen 10 is pushed downward. The pressure compresses multiple springs 14 fixed to the fixed ring 13 at their lower ends. When the extended push rod 12 leaves the protruding inner block 11, the springs 14 rebound and drive the screen 10 to return to its original position. This process is repeated to make the screen 10 vibrate continuously. The powder impurity remover falling from the discharge ring 16 falls onto the vibrating screen 10 and is further dispersed and screened to avoid agglomeration. The dispersed powder enters the cylindrical tank 1 through the screen 10. At this time, the stirring fan blade 8 at the outer end of the driven rotating shaft 6 rotates with the shaft in the cylindrical tank 1 to stir the cobalt acetate solution in the cylindrical tank 1, so that the dispersed powder impurity remover is fully mixed with the solution to complete the impurity removal reaction. The entire process is powered by the motor 4 to realize the synchronous rotation of the linkage rotating shaft 5 and the driven rotating shaft 6, which drives the powder stirring, material control, powder screening, and liquid stirring components to work together to ensure that the powder impurity remover is fed evenly and reacts efficiently with the solution.

[0020] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
