Description

Technical Field

[0001] The utility model relates to the field of battery recycling and processing devices, in particular to a transmission mechanism, a stirrer and a normal pressure leaching reactor. Background Art

[0002] After disassembly, crushing, sorting and other pre-processing steps, waste lithium batteries are obtained into battery black powder. In order to extract valuable metals such as nickel, cobalt, manganese, and lithium from the battery black powder, the wet leaching process is currently mainly used. This process reacts the battery black powder with acid and a reducing agent (such as hydrogen peroxide) to allow the valuable metals in the battery powder to enter the solution.

[0003] During the acid leaching of battery black powder, sulfuric acid and hydrogen peroxide react with positive electrode materials such as Al and Cu to produce H2 and O2. The hydrogen and oxygen produced after leaching mix with organic substances such as battery binders, forming difficult-to-burst bubbles. These bubbles are organically encapsulated and accumulate on the surface of the leachate. As the reaction time increases, the number of bubbles increases, easily overflowing the reaction tank, affecting overall production efficiency and posing a significant production safety risk. Furthermore, the exothermic nature of the acid mixing process causes the temperature of the acid leaching reaction tank to reach approximately 90°C. Under these high temperatures, hydrogen peroxide rapidly decomposes to produce a large number of bubbles. Due to the generation of these bubbles, the powder adsorbed on the bubble surface cannot effectively come into contact with the acid, seriously affecting the leaching of precious metals in the battery black powder.

[0004] In view of this, the present utility model is proposed. Utility Model Content

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0068] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use.

[0098] The first swivel 194, the second swivel 195, and the third swivel 196 are sequentially arranged in the mounting box 199. The end of the second rotating shaft 150 is inserted into the mounting box 199 and passes through the third swivel 196, the second swivel 195, and the first swivel 194. The sleeve 198 is connected to the end of the second rotating shaft 150 by screw threads, and the first swivel 194 is sleeved on the outside of the sleeve 198.

[0099] A first roller groove 194a is defined on a side of the first rotating ring 194 facing the second rotating ring 195, and a second roller groove 195a is defined on a side of the second rotating ring 195 facing the first rotating ring 194. A roller assembly 197 is disposed between the first roller groove 194a and the second roller groove 195a.

[0100] A third roller groove 195b is defined on one side of the second rotating ring 195 facing the third rotating ring 196, and a fourth roller groove 196a is defined on one side of the third rotating ring 196 facing the second rotating ring 195. A roller assembly 197 is disposed between the third roller groove 195b and the fourth roller groove 196a.

[0101] The specific arrangement of the three rotating rings, the roller assembly 197 and the mounting box 199 enables the second rotating shaft 150 to rotate within the mounting box 199 .

[0102] The inner diameter of the second rotating ring 195 is smaller than the outer diameter of the sleeve 198 , so that the sleeve 198 is stuck on the second rotating ring 195 after the device is assembled, preventing the second rotating shaft 150 from falling out of the installation box 199 .

[0103] Alternatively, as Figure 1 and Figure 2 As shown, a third mounting opening 114a is opened on the third fixing member 114, and a third bearing 181 is arranged in the third mounting opening 114a. The inner wall of the third mounting opening 114a is in contact with the outer wall of the third bearing 181. The first rotating shaft 120 passes through the third bearing 181, and the side wall of the first rotating shaft 120 is in contact with the inner wall of the third bearing 181.

[0104] Furthermore, in order to avoid relative rotation between the first rotating shaft 120 and the third gear 141, a groove can be opened between the two, and an anti-rotation pin can be set therein. Its structure and principle are similar to the aforementioned first anti-rotation pin 122 and the second anti-rotation pin 172b, so they will not be elaborated here.

[0105] Alternatively, as Figure 1 and Figure 2 As shown, the fourth gear 142 is connected to the second rotating shaft 150 through the connecting sleeve 182;

[0106] The second rotating shaft 150 is provided with a spline 151 at the location where the fourth gear 142 is mounted. The inner wall of the connecting sleeve 182 is shaped to match the spline 151. The upper portion of the connecting sleeve 182 is sleeved on the spline 151, and the fourth gear 142 is sleeved on the outer wall of the connecting sleeve 182. The provision of the spline 151 prevents relative rotation between the second rotating shaft 150 and the connecting sleeve 182. The spline 151 is, for example, a square spline 151.

[0107] A truncated cone 183 is provided at the lower portion of the connecting sleeve 182 , the fourth gear 142 is located above the truncated cone 183 , the mounting base 110 has a bottom wall, and a fourth bearing 184 is provided between the bottom wall and the truncated cone 183 .

[0108] The above arrangement enables the fourth gear 142 to rotate while driving the second rotating shaft 150 to rotate.

[0109] like Figures 6 to 9 As shown, an embodiment of the present invention further provides an agitator 10, which includes a driving device 11, a stirring paddle 12 and a transmission mechanism 100 provided by the present invention. The driving device 11 is connected to the first rotating shaft 120 for driving the first rotating shaft 120 to rotate; the stirring paddle 12 is arranged on the second rotating shaft 150.

[0110] Since the agitator 10 includes the transmission mechanism 100 provided by the present invention, the agitator 12 can stir in the horizontal direction and the vertical direction when in use. When the agitator 10 is used in an environment where bubbles are easily generated, the up and down movement of the agitator 12 can enhance the turbulence of the liquid. The turbulence of the liquid surface causes the bubbles on the surface to collide with each other to achieve the effect of eliminating bubbles, while making the solid-liquid mixing more uniform.

[0111] Optionally, the number of stirring paddles 12 may be two, and the two stirring paddles 12 are distributed along the length direction of the second rotating shaft 150. It should be noted that in other embodiments of the present invention, the number of stirring paddles 12 may be greater than two.

[0112] Furthermore, each stirring paddle 12 is a downward pressure three-blade paddle.

[0113] Furthermore, when the agitator is used in the atmospheric pressure leaching reactor 1, the diameter of the downward pressure three-blade paddle is 55% of the inner diameter of the leaching tank.

[0114] Specifically, the driving device 11 is composed of a variable frequency reducer motor and a frame. The variable frequency reducer motor can control the up and down reciprocating motion frequency of the reciprocating mechanism and the stirring speed of the stirring paddle 12.

[0115] Furthermore, the agitator also includes a defoaming paddle 13, which is arranged on the second rotating shaft 150 and is located above the stirring paddle 12; the defoaming paddle 13 includes a mounting cross bar 13a, which is arranged on the second rotating shaft 150, and a plurality of bubble-piercing parts 13b are evenly arranged downward on the mounting cross bar 13a.

[0116] When the agitator is used in a scenario where bubbles are easily generated, the defoaming paddle 13 can destroy the bubbles through shearing and impacting effects, thereby further effectively eliminating the bubbles.

[0117] Furthermore, when the agitator is used in the atmospheric pressure leaching reactor 1, the length of the installation cross bar 13a is 70% of the inner diameter of the leaching tank, and the installation height is more than 15% from the liquid surface.

[0118] like Figures 6 to 9 As shown, the present invention further provides a normal pressure leaching reactor 1, which includes a normal pressure leaching tank 20 and an agitator provided by the present invention.

[0119] The top of the atmospheric pressure leaching tank 20 is equipped with a slurry feed pipe, a reducing agent feed pipe, an acid feed pipe, and an exhaust gas discharge pipe. An overflow pipe is arranged on the side. A manhole is opened at the top of the atmospheric pressure leaching tank 20 for easy observation and sampling. A discharge port is set at the bottom of the atmospheric pressure leaching tank 20. The top of the atmospheric pressure leaching tank 20 is equipped with a liquid level gauge that penetrates into the atmospheric pressure leaching tank 20 to detect the reaction liquid level. A thermometer is provided for real-time monitoring of the reaction temperature. A pressure gauge is provided to measure the pressure within the atmospheric pressure leaching tank 20.

[0120] The atmospheric pressure leaching reactor 1 provided by the present invention includes an agitator provided by the present invention. The up-and-down motion of the agitator paddle 12 enhances liquid turbulence. This turbulence on the liquid surface causes bubbles on the surface to collide with each other, eliminating bubbles and achieving more uniform solid-liquid mixing, thereby improving metal leaching efficiency. In a preferred embodiment, the shearing and impacting effects of the defoaming paddle 13 destroy bubbles on the liquid surface, accelerating their escape and effectively controlling the risk of foaming.

[0121] In summary, the present invention has the following features:

[0122] 1. The reasonable setting of the transmission mechanism 100 can enable the shaft to achieve reciprocating motion and rotation;

[0123] 2. The transmission mechanism 100 is applied to a stirrer to enable the stirring paddle 12 to reciprocate up and down and rotate. When the stirrer is used in an environment prone to bubble generation, the up and down movement and rotation of the stirring paddle 12 can enhance the turbulence of the liquid. The turbulence of the liquid surface causes bubbles on the surface to collide with each other, thereby achieving the effect of eliminating bubbles, while also making the solid-liquid mixing more uniform and improving the reaction rate.

[0124] 3. The agitator is applied to the atmospheric pressure leaching reactor 1, which has a better defoaming effect and improves the metal leaching efficiency;

[0125] 4. In a preferred embodiment, the agitator also includes a defoaming paddle 13, which destroys bubbles on the liquid surface through the shearing and impact effects of the defoaming paddle 13, accelerates the escape of bubbles, and effectively controls the risk of tank bubbling in the atmospheric pressure leaching reactor 1; can effectively control the gas content in the leaching tank and increase the volume utilization rate of the leaching tank by more than 10%; enhances the uniformity of solid-liquid mixing, and the leaching efficiency of precious metals in battery black powder of the device is increased by more than 25% compared with the original leaching efficiency.

[0126] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
