In addition, during the mixing of raw materials, oxidation may occur, resulting in the presence of aluminum and copper impurities in the mixed materials, thereby affecting the purity of the raw material leaching. For this reason, we provide a lithium leaching device for reducing the dissolution of copper and aluminum to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For specific embodiment 1, please refer to Figure 1-4 The utility model is a lithium immersion device for reducing the dissolution of copper and aluminum, comprising a tank body 1, a PLC programming controller 2 is fixedly connected to the outer surface of the tank body 1, a top cover 3 is detachably connected to the upper surface of the tank body 1, a motor 4 is fixedly connected to the upper surface of the top cover 3, a connecting rod 5 is fixedly connected to the output end of the motor 4, a plurality of stirring blades 6 are fixedly connected to the outer surface of the connecting rod 5, an air inlet pipe 7 is fixedly connected to the tank body 1, an air outlet coil 8 is fixedly connected to the air inlet pipe 7, a plurality of air outlets 9 are provided on the air outlet coil 8, a heating coil 10 is fixedly connected to the inner surface of the tank body 1, and an intelligent pH meter 11 and a temperature sensor 12 are respectively fixedly connected to the tank body 1.

[0027] Specifically, a feed pipe 13 is fixedly connected to the upper surface of the tank body 1, and the feed pipe 13 is connected to the tank body 1. A liquid inlet pipe 14 is fixedly connected to the upper surface of the tank body 1, and the liquid inlet pipe 14 is connected to the tank body 1. Through the arrangement of the feed pipe 13 and the liquid inlet pipe 14, raw materials and leachate can be added to the tank body 1.

[0028] For specific embodiment 2, please refer to Figure 1-4 On the basis of the first specific embodiment, a discharge pipe 15 is fixedly connected to the lower surface of the tank body 1, and a discharge valve 16 is arranged on the outer surface of the discharge pipe 15. The discharge pipe 15 is communicated with the tank body 1, and the discharge valve 16 is electrically connected to the PLC programming controller 2.

[0029] Specifically, by setting the discharge valve 16, it is possible to control whether the discharge pipe 15 can perform the discharge operation, thereby preventing the raw materials from flowing directly through the discharge pipe 15 during the mixing process in the tank body 1. At the same time, the PLC programming controller 2 can control the opening and closing of the discharge valve 16, and the bottom of the tank body 1 is conical, so it is convenient to discharge the mixed material through the discharge pipe 15.

[0030] For specific embodiment 3, please refer to Figure 1-4 On the basis of the first and second specific embodiments, the outer surface of the tank body 1 is fixedly connected with support legs 17, the number of the support legs 17 is four and they are distributed in a circular array, the tank body 1 is fixedly connected with an exhaust pipe 18, the PLC programming controller 2 is electrically connected with the motor 4 and the heating coil 10 respectively, the connecting rod 5 passes through the top cover 3, the top cover 3 and the kettle body are separated, which can be easily cleaned, and the outer surfaces of the connecting rod 5 are rotatably connected with the tank body 1 and the top cover 3 respectively.

[0031] Specifically, through the setting of the PLC programming controller 2, the motor 4 and the heating coil 10 can be controlled so as to switch the motor 4 and the heating coil 10. At the same time, under the action of the supporting legs 17, the entire device can be supported, and under the setting of the exhaust pipe 18, the air pressure in the tank body 1 can be discharged to the outside to avoid excessive air pressure in the tank body 1.

[0032] The working principle of the utility model is as follows: leachate is added into the tank body 1 through the liquid inlet pipe 14, and nitrogen is added into the tank body 1 through the air inlet pipe 7, and then the motor 4 and the heating coil 10 are started by the PLC programming controller 2, so that the started heating coil 10 generates heat to heat the leachate in the tank body 1, so that the raw material can have a certain temperature after entering the tank body 1, and at the same time, the started motor 4 will drive the connecting rod 5 and the stirring blade 6 to rotate, and finally the lithium raw material is added into the tank body 1 through the feeding pipe 13. When the raw material enters the tank body 1, the rotating stirring blade 6 will drive the leachate in the tank body 1 to flow, so that the raw material in the tank body 1 can move in the leachate, and at the same time, the nitrogen added through the air inlet pipe 7 will be blown out through the air outlet 9 on the air outlet coil 8. Since the air outlet 9 is located in the leachate, bubbles will be generated when blowing upwards, and the rotating stirring blade 6 is located above the air outlet 9, so bidirectional up and down spiral mechanical stirring can be realized. The stirring of the air bubbles and the stirring of the bubbles can realize centrifugal mixing, accelerate the mixing of the upper and lower layer materials with the leachate, and make the acidity of each interval in the leaching equipment evenly distributed, thereby improving the mixing efficiency. At the same time, under the action of nitrogen, the effect of the oxidation reaction of the raw material is reduced, thereby reducing the generation of impurities such as aluminum and copper on the raw material. At the same time, under the action of the temperature sensor 12, it is easy to observe the temperature of the leachate in the tank body 1. When the temperature is too low or too high, the temperature of the heating coil 10 can be changed through the PLC programming controller 2, so that the raw material can be kept at a stable temperature for mixing. At the same time, under the action of the intelligent pH meter 11, it is easy to observe the pH value of the leachate in the tank body 1, so that the degree of lithium leaching reaction can be understood. And under the action of the exhaust pipe 18, the air pressure in the tank body 1 can be discharged to the outside to avoid excessive air pressure in the tank body 1. When the lithium leaching is completed, the unloading valve 16 is started by the PLC programming controller 2, so that the material in the tank body 1 can be discharged through the discharge pipe 15.
