[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This conductive slurry processing system with a magnetic adsorption structure offers two technical solutions:

[0024] The first embodiment includes a mixing drum 1, with a feeding port 8 and a discharging port 9 respectively provided at the top and bottom of the mixing drum 1. A controller is fixedly installed on the outside of the mixing drum 1 by a bracket. An adjustable magnetic suction component 4 is connected to the controller by an electrical signal. A mixing component 2 is provided inside the mixing drum 1. A magnetic adsorption mechanism is also provided inside the mixing drum 1. The magnetic adsorption mechanism includes multiple adjustable magnetic suction components 4 and a lifting component 5.

[0025] Multiple grooves 3 are provided circumferentially on the inner surface of the stirring drum 1, and guide grooves 31 are provided on both sides of the grooves 3. Multiple adjustable magnetic suction components 4 are arranged inside the grooves 3. The adjustable magnetic suction components 4 are mounted on the lifting component 5 through the mounting component 6. The adjustable magnetic suction components 4 include a protective box 41. A bracket 42 is fixedly connected between the inner walls of the protective box 41. A permanent magnet 43 is fixedly installed inside the bracket 42. An electromagnetic coil 44 is wound around the outside of the bracket 42. When the electromagnetic coil 44 is energized, the magnetic field generated by it will be superimposed with the magnetic field of the permanent magnet 43, causing the magnetic pole direction of the permanent magnet 43 to change.

[0026] The lifting assembly 5 includes a circular frame 51 and two hydraulic cylinders 52. The equipment is equipped with a hydraulic control system for controlling the operation of the hydraulic cylinders 52. Two symmetrical connecting plates 53 are fixedly connected to the inner side of the circular frame 51. Both hydraulic cylinders 52 are fixedly connected to the bottom of the mixing drum 1, and the telescopic ends of the two hydraulic cylinders 52 are fixedly connected to the bottom of the two connecting plates 53 respectively. A conductive component 55 is provided on the circular frame 51. Hollow slide rods 54 are fixedly connected to the top of the two connecting plates 53, and the hollow slide rods 54 penetrate the mixing drum 1 and extend to the top of the mixing drum 1.

[0027] The conductive component 55 includes an internal wire arranged inside the ring frame 51. Multiple sockets 551 are fixedly connected at equal intervals along the circumference of the outer surface of the ring frame 51, and the multiple sockets 551 are connected to the internal wire. A plug 552 is fixedly connected to the bottom of the adjustable magnetic component 4. The plug 552 is inserted into the socket 551 and is connected to the electromagnetic coil 44. The terminal of the internal wire inside the ring frame 51 is connected to an external wire 553, and the external wire 553 passes through the hollow slide bar 54 and extends to the outside of the hollow slide bar 54.

[0028] The magnetic adsorption mechanism enables efficient mixing of conductive slurry and uniform distribution of magnetic particles. The dynamic magnetic field control of the adjustable magnetic adsorption component 4 solves the shortcomings of existing equipment in terms of magnetic particle orientation control, anti-agglomeration control and internal wall residue cleaning, and significantly improves slurry processing quality and equipment operating efficiency.

[0029] The second embodiment differs from the first embodiment in that the mounting component 6 includes a U-shaped mounting groove 61 formed in the ring frame 51, the adjustable magnetic component 4 is placed in the ring frame 51, and the top of the ring frame 51 is fixedly connected to a pressure block 62 by an internal hex bolt 63, and the pressure block 62 presses on the adjustable magnetic component 4.

[0030] The adjustable magnetic suction component 4 is installed on the lifting component 5 via the mounting component 6. When the adjustable magnetic suction component 4 needs to be inspected or replaced, it can be quickly installed and removed.

[0031] When installing the adjustable magnetic suction component 4, place it into the U-shaped mounting groove 61, with the adjustable magnetic suction component 4 positioned inside the sliding groove 3. During placement, align the plug 552 with the socket 551 and insert the plug 552 into the socket 551. After insertion, place the pressure block 62 on top of the adjustable magnetic suction component 4 and finally fix the pressure block 62 with the hexagonal socket bolt 63. When the conductive slurry is being stirred, the adjustable magnetic suction component 4 begins to work. The permanent magnet 43 and the electromagnetic coil 44 work together, and the current intensity of the electromagnetic coil 44 is adjusted by the external power module to dynamically change the magnetic field distribution. The magnetic particles in the slurry are affected by the magnetic field and are oriented and evenly distributed along the magnetic field direction. Since the adjustable magnetic suction component 4 is connected to the lifting component 5 and its position can be adjusted by the hydraulic cylinder 52, the magnetic pole unit can move along the axial direction of the stirring drum 1, expanding the range of magnetic field action and ensuring the uniform dispersion of magnetic particles in the slurry. This dynamic magnetic field design also effectively prevents the agglomeration of magnetic particles and improves the overall stability of the slurry.
