Description

Technical Field

[0001] This utility model belongs to the field of battery recycling technology, and in particular relates to a stirred leaching tank. Background Technology

[0002] In the power battery recycling process, refining and leaching black powder is a core step. This process involves a three-phase reaction of gas, liquid, and solid, where the degree of mixing and contact time of the three phases directly affect the final leaching effect. For this type of three-phase reaction, gas is usually introduced through gas distribution pipes in a gas distribution device, and these pipes are often located at the bottom of the stirred leaching tank. In traditional gas distribution pipe designs, gas is introduced from the top of the stirred leaching tank. However, because the gas distribution pipes are installed below the agitator, the gas distribution holes are prone to clogging during the black powder leaching process. Whenever clogging occurs, workers have to enter the stirred leaching tank to maintain and clean the gas distribution pipes, which undoubtedly increases the complexity of operation and maintenance and reduces overall work efficiency.

[0003] Therefore, there is an urgent need for a gas-liquid-solid three-phase reaction stirring leaching tank for leaching battery black powder that is easy to disassemble and install, so as to realize external cleaning operations, avoid the cumbersome steps of cleaning inside the tank, improve the cleaning conditions of the gas distribution pipe, and effectively save cleaning time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the deficiencies and defects mentioned in the background art above, and to provide a gas, liquid and solid three-phase reaction stirring leaching tank for leaching battery black powder that is easy to disassemble and install and easy to maintain.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0006] A gas-liquid-solid three-phase reaction stirring leaching tank for leaching battery black powder includes a tank body, a gas distribution pipe in the tank body, a first interface pipe at the bottom of the tank body for the gas distribution pipe to extend into the tank body, an air inlet pipe connected to the gas distribution pipe, and the gas distribution pipe is detachably installed in the tank body through the first interface pipe, and the gas distribution pipe is sealed to the first interface pipe.

[0007] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, a second interface pipe is also provided on the tank body. The first interface pipe and the second interface pipe are arranged opposite to each other. One end of the gas distribution pipe is detachably and sealed to the first interface pipe, and the other end is locked in the second interface pipe. By providing opposite first and second interface pipes on the three-phase reaction stirring leaching tank, and by detachably and sealed one end of the gas distribution pipe to the first interface pipe and locking the other end to the second interface pipe, the gas distribution and tank structure are optimized. This design makes the installation and disassembly of the gas distribution pipe more convenient, and facilitates maintenance and replacement.

[0008] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, a fourth flange is provided at the port of the second interface pipe, and a blind flange is detachably connected to the port of the second interface pipe via the fourth flange. The fourth flange and the blind flange are fixed together by a bolt assembly. Providing a fourth flange at the port of the second interface pipe and fixing the blind flange to the flange using a bolt assembly not only ensures the sealing and safety of the pipeline connection but also facilitates quick disassembly and replacement of the blind flange, improving equipment maintenance efficiency and operational convenience.

[0009] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, a sealing gasket is provided between the fourth flange and the blind plate. The sealing gasket between the fourth flange and the blind plate enhances the sealing performance of the connection, effectively preventing gas or liquid leakage and ensuring the safety and stability of the reaction process.

[0010] In the aforementioned gas-liquid-solid three-phase reaction stirred leaching tank, preferably, a first flange is provided at the end of the gas distribution pipe near the first interface pipe, a second flange is provided at the pipe opening of the first interface pipe, and the gas inlet pipe is fixed to a third flange. The first flange is sandwiched between the second and third flanges, and the three are fixed together by a bolt assembly. The bolt assembly securely connects the first, second, and third flanges, forming a stable integrated structure from the first interface pipe, the gas distribution pipe, and the gas inlet pipe. This connection offers high reliability, not only improving the system's sealing performance and preventing gas leakage, thus ensuring the safety of the three-phase reaction stirred leaching tank, but also allowing for quick disassembly and installation, facilitating daily maintenance and repair.

[0011] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, gaskets are provided between the first and second flanges, and between the first and third flanges. These gaskets effectively prevent gas or liquid leakage, ensuring the sealing of the connections and helping to maintain the stability and safety of the reaction environment within the tank.

[0012] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, the end of the gas distribution pipe furthest from the gas inlet pipe is provided with a plug to prevent gas leakage. The plug, located at the end of the gas distribution pipe, effectively prevents gas leakage from the end of the pipe, ensuring the airtightness and safety of the gas during the reaction process.

[0013] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, multiple rows of gas distribution holes are formed in the middle of the gas distribution pipe, with these multiple rows of gas distribution holes arranged in an alternating pattern. Forming multiple rows of alternating gas distribution holes in the middle of the gas distribution pipe optimizes the gas distribution path within the tank, reduces dead zones in gas flow, and achieves uniform and efficient gas distribution within the tank. This improves the efficiency and uniformity of the three-phase reaction, thereby enhancing the operational performance of the leaching tank and the product quality.

[0014] In the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, preferably, three rows of gas distribution holes are provided in the middle of the gas distribution pipe, with one row of holes facing directly upwards and the other two rows inclined upwards, the included angle between adjacent rows of gas distribution holes being α degrees. This design, with the middle row vertically upwards and the other two rows inclined upwards at an angle of α degrees, optimizes gas distribution, reduces dead zones in gas flow, and enables uniform gas distribution in multiple directions and layers within the tank. This results in more thorough mixing between the gas, liquid, and solid phases, thereby improving the uniformity and efficiency of the three-phase reaction.

[0015] Preferably, in the aforementioned gas-liquid-solid three-phase reaction stirring leaching tank, the tank is equipped with a stirring device for fully mixing the gas, liquid, and solid media, and the stirring device is located directly above the gas distribution hole. Positioning the stirring device directly above the gas distribution hole promotes the mixing efficiency and rate of the gas, liquid, and solid media, not only accelerating the reaction speed but also improving the leaching efficiency, ensuring the uniformity and completeness of the reaction process, thereby improving the overall process performance and the quality of the final product.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The gas-liquid-solid three-phase reaction stirring leaching tank of this utility model has a gas distribution pipe that is detachably installed in the tank body and sealed to the first interface pipe. This not only facilitates the installation and maintenance of the gas distribution pipe and avoids the cumbersome steps of cleaning the tank, but also improves the cleaning conditions of the gas distribution pipe, saves cleaning time, effectively prevents gas leakage, and improves the safety and efficiency of the leaching process.
