[0023] according to Figure 7 and Figure 8 As shown, the recovery and adjustment component 14 includes a slide groove connecting frame 141, and the interior of the slide groove connecting frame 141 is slidably connected to a connecting support slide 142, and an electric telescopic guide rod 143 is installed on the side end of the connecting support slide 142, and a docking outer tube 147 is installed on the top of the electric telescopic guide rod 143. The side wall surface of the docking outer tube 147 is connected to a telescopic guide tube 146 through an electric iris valve, and the docking outer tube 147 and the docking sealing core hole 21 are plugged together. After the cobalt oxide is treated, the electric telescopic guide rod 143 is started under the control of an external controller, so that the connecting support slide 142 can slide and adjust its position in the slide groove of the slide groove connecting frame 141. In conjunction with the telescopic action of the electric telescopic guide rod 143, the position of the docking outer tube 147 can be adjusted according to actual needs, so that the docking outer tube 147 and the docking sealing core hole 21 are plugged together, and the generated cobalt oxide is guided to the collection and drying air chamber 145 through the telescopic guide tube 146 controlled by the electric iris valve.

The model is selected according to the actual use, so the control method and wiring layout of the brushless motor 4, nanocellulose adsorption roller 86, photoelectric sensor 88, position sensor 9, servo control motor 1491 and temperature control adjustment box will not be explained in detail.

[0030] The method of using the device and the working principle are as follows: first, the PTA residue is placed in the treatment tank 1 through a separate addition hole formed by the addition end 2 set as a double-pass addition hole, and the brushless motor 4 is controlled by the external controller to drive the second transmission gear 5 and the first transmission gear 6 to drive the stirring and crushing structure 19 to stir the PTA residue in the treatment tank 1, and water is added through an external peristaltic pump in cooperation with the density sensor built into the treatment tank 1 according to the stirring property, and then an alkaline solvent or a chelating agent is added through the addition hole on the other side of the addition end 2 set as a double-pass addition hole, and the pH value of the solution is adjusted to 9-10 by the Hengel reaction to neutralize the acidic substances in the PTA residue, and promote the formation of hydroxide precipitation of cobalt and manganese, and then the cobalt and manganese are added through the guide valve pipe 11. Manganese forms hydroxide precipitation and is guided to the small turntable tower 12, so that under the cooperation of the small turntable tower 12 and the built-in separation membrane, when working, cobalt and manganese form hydroxide precipitation liquid (continuous phase) flowing from top to bottom, and the chelating agent (dispersed phase) is sprayed onto the disk surface through the small holes on the turntable and rotates with the disk surface. The two phases are fully in contact and mass transfer on the disk surface, and then other substances are discharged from the tower's chip discharge pipe 17, and the initially formed cobalt oxide is transported from the recovery pipe 13, and the remaining liquid and PTA residue waste are discharged through the waste discharge valve end. After the operation of the small turntable tower 12, under the cooperation of the recovery material pump 15 and the adsorption guide pipe 16, the adsorption ultrafiltration membrane in the adsorption guide pipe 16 performs adsorption operation to further purify or treat the initially formed The cobalt oxide is formed, and then the material to be operated is transported to the temperature control box, and with the cooperation of the temperature control box and the built-in high-precision temperature sensor, the temperature is adjusted in the range to obtain the best operating environment for the recovery of the cobalt oxide. After the initially formed cobalt oxide enters the temperature control box, under the drive of the brushless motor 4, the second transmission gear 5 and the rotating adjustment rod 7 are rotated synchronously and in the same direction, so as to drive the first bevel gear 81 to form an operation, and then according to the rotation of the first bevel gear 81, the second bevel gear 82 is driven to cooperate with the speed regulator 87, so that the central guide shaft 84 drives the connecting rod 85 and the nanocellulose adsorption roller 86 to rotate inside the temperature control box, so that when the generated cobalt oxide and liquid fall into the ultrafiltration membrane layer frame 2 2 surface, the ultrafiltration membrane frame 22 and the cobalt oxide filtered on the surface are monitored by the photoelectric sensor 88. When the preset value is reached, the nanocellulose adsorption roller 86 will contact the cobalt oxide filtered on the surface of the ultrafiltration membrane frame 22, and the fiber structure of the nanocellulose adsorption roller 86 can selectively adsorb the cobalt oxide particles according to its physical and chemical properties. Then, after the cobalt oxide is treated, the electric telescopic guide rod 143 is started under the control of the external controller, so that the connecting support slide 142 can slide and adjust the position in the slide groove of the slide groove connecting frame 141. With the telescopic action of the electric telescopic guide rod 143, the position of the docking outer tube 147 can be adjusted according to actual needs, so that the docking outer tube 147 and the docking sealing core hole 21 can be plugged in.The generated cobalt oxide is guided to the collection and drying air chamber 145 by the telescopic guide tube 146 controlled by the electric iris valve. Under the action of the collection and drying air chamber 145, the generated cobalt oxide is fully dried. When the docking outer tube 147 and the docking sealing core hole 21 are plugged in, the docking outer tube 147 and the nanocellulose adsorption roller 86 are buckled, that is, when the nanocellulose adsorption roller 86 is adjusted to stop at the docking sealing core hole 21, the docking outer tube 147 is inserted and the nanocellulose adsorption roller 86 is wrapped. Then the external controller starts the servo control motor 1491, so that the servo control motor 1491 drives the gear set 1490 to rotate, so that the inner rotating tube 148 rotates when the docking outer tube 147 is connected. When the inner rotating tube 148 rotates, The multiple groups of micro-recovery and cleaning ends 149 on the inner rotating tube 148 can recover and clean the cobalt oxide particles adsorbed on the surface of the nanocellulose adsorption roller 86. At the same time, the nanocellulose adsorption roller 86 after adsorption saturation can be regenerated through a specific desorption process (such as changing the pH value, temperature or using a specific solvent) to release the adsorbed cobalt oxide, so that the multiple groups of micro-recovery and cleaning ends 149 can collect the cobalt oxide more comprehensively. The overall device effectively recovers the cobalt oxide in the PTA residue, improves the recycling rate of resources, reduces resource waste, and reduces the cross infection of cobalt oxide during recovery. Through the multi-stage purification formed, the high purity of the finally recovered cobalt oxide is ensured, avoiding the efficiency and purity of the cobalt oxide recovery being affected.
