Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to a battery powder resource extraction device. Background Art

[0002] In the field of modern industry and environmental protection, the resource treatment and recycling of waste batteries has become an important research topic. Batteries contain a variety of valuable metals and chemicals, such as lithium, cobalt, nickel, manganese, etc. These substances not only have important economic value, but also are related to environmental protection and sustainable use of resources. However, in the process of processing waste batteries, how to extract and separate these valuable components efficiently and environmentally friendly is still a problem that needs to be solved.

[0003] Traditional battery powder processing methods usually include steps such as crushing, screening, leaching, and precipitation. After the precipitation is completed, when the multiphase solution formed by extraction and precipitation separation is discharged, a discharge port is usually set at the bottom of the extraction device, and the multiphase solution is discharged from the bottom. During the discharging process, the multiphase solution flows to the discharge port under the action of gravity. The boundary between the two adjacent solutions is always moving towards the discharge port, resulting in unclear boundaries and inability to ensure that the multiphase solutions are discharged separately in sequence. Utility Model Content

Under the action of the adjustment component, the multiphase solution is sucked out from top to bottom in sequence through the liquid outlet component, so that the boundary height of the multiphase solution changes little, and the multiphase solution is discharged separately simply and accurately.

[0006] Furthermore, the liquid outlet assembly includes a liquid pump and a suction piece, wherein the liquid pump is fixedly arranged outside the extraction kettle, the suction piece is arranged inside the extraction kettle, the output end of the liquid pump is connected to a liquid outlet pipe, and the input end of the liquid pump is connected to the suction piece through a hose. The multiphase solution is extracted by the cooperation of the liquid pump and the suction piece.

[0007] Furthermore, the suction member includes an annular tube connected to the liquid outlet pipe, the annular tube is located outside the stirring mechanism, and the lower surface of the annular tube is evenly provided with liquid suction heads connected to the annular tube. Liquid is pumped from multiple positions on the same horizontal plane by multiple liquid suction heads arranged on the lower surface of the annular tube, thereby improving the liquid pumping efficiency and ensuring that the boundary height change is minimized.

[0008] Furthermore, the adjusting assembly includes an adjusting screw and a connecting piece, one side of the connecting piece is fixedly arranged on the annular tube, and the other side is fixedly connected to the adjusting screw, the adjusting screw passes through the extraction kettle and is connected to a transmission member arranged outside the extraction kettle. The height of the annular tube is adjusted by the adjusting screw, that is, the suction height is adjusted.

[0009] Furthermore, the transmission member includes a second servo motor, a motor gear and a transmission wheel. The second servo motor is fixedly arranged on the extraction kettle through a bracket. The output end of the second servo motor is fixedly connected to the motor gear. The transmission wheel is screwed on the screw. The transmission wheel is provided with a toothed ring meshing with the motor gear on the outside. The longitudinal movement of the screw is achieved through the cooperation of the motor gear and the transmission wheel, and the height of the annular tube is adjusted.

[0010] Furthermore, the adjustment assembly further comprises a guide rod, one end of which is fixedly arranged on the annular tube, and the other end of which passes through the extraction kettle and is slidably connected to the extraction kettle. The guide rod can ensure stable movement of the annular tube.

[0011] Furthermore, the extraction kettle is also provided with a height detector for detecting the height of the multiphase solution. An ultrasonic sensor or an X-ray densitometer can be used to detect the height limits of the multiphase solution in conjunction with suction.

[0012] Furthermore, the stirring mechanism includes a first servo motor, a rotating rod and a stirring blade. The first servo motor is fixedly arranged on the extraction kettle through a bracket. The output end of the first servo motor is fixedly connected to the rotating rod located in the center of the extraction kettle. The rotating rod is provided with a stirring blade, and the annular tube is arranged on the periphery of the stirring blade. The stirring blade is driven by the servo motor to stir and mix the battery powder and the solvent.

[0013] The utility model provides a battery powder resource extraction device, which discharges materials from top to bottom through an annular tube, so that the boundary height of the multiphase solution changes less. In conjunction with a height detector, it is convenient to measure the boundary height of the multiphase solution during the discharge process, and the separate discharge of the multiphase solution is completed simply and accurately, thereby effectively improving the extraction efficiency.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] like Figure 1 As shown, the conventional battery powder resource extraction device includes an extraction kettle 1 for containing a solution and a stirring mechanism disposed in the extraction kettle 1. The extraction kettle 1 is provided with a feeding pipe, which can feed the inside of the extraction kettle 1. The fed battery powder and the solvent are stirred and mixed by the stirring mechanism. When discharging, the solution is usually discharged through a discharge port opened at the bottom of the extraction kettle 1. However, the multiphase solution flows to the discharge port under the action of gravity, and the boundary between the two adjacent solutions is always moving toward the discharge port, resulting in unclear boundaries, and it is impossible to ensure that the multiphase solutions are discharged in sequence, wherein the boundary is the contact position between the two solutions.

[0022] like Figure 2As shown, specifically, the stirring mechanism includes a first servo motor 2, a rotating rod 3 and a stirring blade 4. The first servo motor 2 is fixedly arranged on the extraction kettle 1 through a bracket. The output end of the first servo motor 2 is fixedly connected to the rotating rod 3 located at the center of the extraction kettle 1. The rotating rod 3 is provided with the stirring blade 4, and the annular tube 8 is arranged on the periphery of the stirring blade 4. By starting the first servo motor 2, the rotating rod 3 and the stirring blade 4 can be driven to rotate, so that the stirring blade 4 stirs and mixes the battery powder and the solvent.

[0023] In order to simply and accurately discharge the multiphase solution separately, a battery powder resource extraction device is designed. Figure 2 As shown, the extraction kettle 1 is also provided with a liquid discharge component for extracting the solution, and the liquid discharge component is arranged in the extraction kettle 1 through an adjustment component and can be moved along the height direction of the extraction kettle 1. The height of the liquid suction head 9 of the liquid discharge component is adjustable. After extraction, precipitation and separation, the height of the liquid suction head 9 is adjusted according to the boundary height of the two-phase liquid, and the solution located at a high place is discharged until the liquid is discharged to the boundary height, and the discharge of the single-phase solution is completed. Repeating the above steps can complete the discharge of the multi-phase solution. In the process of discharging, since the discharge is carried out in a top-down manner, the boundary height of the multi-phase solution changes less. The extraction kettle 1 is also provided with a height detector 17 for detecting the height of the multi-phase solution, which is convenient for measuring the boundary height of the multi-phase solution during the discharging process, and completing the separate discharge of the multi-phase solution simply and accurately.

[0024] like Figure 3 As shown, the liquid outlet assembly includes a liquid pump 5 and a suction piece, the liquid pump 5 is fixedly arranged outside the extraction kettle 1, the suction piece is arranged inside the extraction kettle 1, the output end of the liquid pump 5 is connected to a liquid outlet pipe 6, and the input end of the liquid pump 5 is connected to the suction piece through a hose 7. In order to adjust the height of the liquid outlet assembly, an adjustment assembly connected to the liquid outlet assembly is installed on the extraction kettle 1, and the height of the liquid suction head 9 can be adjusted by adjusting the height of the liquid outlet assembly.

[0025] The suction member includes an annular tube 8 connected to the liquid outlet pipe 6, the annular tube 8 is located outside the stirring mechanism, and the lower surface of the annular tube 8 is evenly provided with liquid suction heads 9 connected to the annular tube 8. Through multiple liquid suction heads 9, liquid can be pumped from multiple positions on the same horizontal plane synchronously, thereby improving the liquid pumping efficiency and minimizing the change range of the limit height.

[0026] The adjustment assembly includes an adjustment screw 11 and a connecting piece 10. One side of the connecting piece 10 is fixedly arranged on the annular tube 8, and the other side is fixedly connected to the adjustment screw 11. The adjustment screw 11 passes through the extraction kettle 1 and is connected to a transmission member arranged outside the extraction kettle 1. By starting the transmission member, the transmission wheel 12 can be driven to rotate. When the transmission wheel 12 rotates, it will drive the adjustment screw 11 to move vertically to adjust the height of the annular tube 8. After the adjustment is completed, the height of the annular tube 8 can be locked. In order to ensure the stable adjustment of the annular tube 8, the adjustment assembly also includes a guide rod 16. One end of the guide rod 16 is fixedly arranged on the annular tube 8, and the other end passes through the extraction kettle 1 and is slidably connected to the extraction kettle 1.

[0027] like Figure 4 As shown, the transmission member includes a second servo motor 14, a motor gear 15 and a transmission wheel 12. The second servo motor 14 is fixedly arranged on the extraction kettle 1 through a bracket. The output end of the second servo motor 14 is fixedly connected to the motor gear 15. The transmission wheel 12 is screwed on the adjusting screw 11. The transmission wheel 12 is provided with a toothed ring 13 meshing with the motor gear 15 on the outside. The motor gear 15 can be driven to rotate by starting the second servo motor 14. When the motor gear 15 rotates, it drives the transmission wheel 12 to rotate through the toothed ring 13, thereby effectively completing the transmission.
