Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0030] Embodiment: Please refer to Figures 1 to 5 A soft magnetic ferrite magnetic core pulping device, comprising a magnetic core pulping cylinder 1, the top of the magnetic core pulping cylinder 1 is connected with an adding pipe in a lead-through manner, which is used for adding water, dispersing agent, thickening agent and the like into the magnetic core pulping cylinder 1; a discharge hopper is integrally formed at the lower end of the magnetic core pulping cylinder 1, the bottom of the discharge hopper is connected with a discharge pipe in a lead-through manner, and a valve is installed on the discharge pipe, which is used for discharging the mixed slurry.

[0031] The embodiment further comprises a hollow stirring shaft 2, a mounting shell 3, a rotary drive assembly 4, a plurality of stirring parts 5, a feeding ring pipe 6, a plurality of feeding holes 7 and a reciprocating lifting mechanism 8.

[0032] The hollow stirring shaft 2 is rotatably connected in the magnetic core pulping cylinder 1 through the cooperation of a bearing and a shaft seat, the upper end of the hollow stirring shaft 2 extends into the mounting shell 3, and the hollow stirring shaft 2 is conveniently transmissionally connected with the rotary drive assembly 4. The axis of the hollow stirring shaft 2 coincides with the axis of the magnetic core pulping cylinder 1. The mounting shell 3 is fixed to the outer top of the magnetic core pulping cylinder 1, and provides mounting space for other components in the device.

[0033] Secondly, the rotary drive assembly 4 is installed in the mounting shell 3 and is transmissionally connected with the hollow stirring shaft 2. Specifically, as shown in the figure, Figure 1As shown, the rotating driving assembly 4 comprises a driving motor 401 fixedly installed in the installation shell 3, a first bevel gear 402 fixedly connected at the output end of the driving motor 401, and a second bevel gear 403 fixed on the hollow stirring shaft 2 and engaged with the first bevel gear 402. When the driving motor 401 works, the hollow stirring shaft 2 can be driven to rotate along the axis of the magnetic core pulping cylinder 1 through the cooperation of the first bevel gear 402 and the second bevel gear 403, so as to mix the slurry through the stirring member 5.

[0034] In addition, a plurality of stirring members 5 are fixedly installed on the hollow stirring shaft 2 in the vertical direction. In the embodiment, as shown in Figure 1 and Figure 4 shown, the stirring member 5 is composed of two stirring blades which are fixed on the hollow stirring shaft 2 in a left-right symmetry. When the hollow stirring shaft 2 rotates, the stirring blades can stir and mix the slurry in the magnetic core pulping cylinder 1.

[0035] In the embodiment, as shown in Figure 1 , the feeding ring pipe 6 is located in the gap between the stirring member 5 and the magnetic core pulping cylinder 1, the center line of the feeding ring pipe 6 coincides with the axis of the hollow stirring shaft 2, and the feeding ring pipe 6 can move up and down along the axis of the hollow stirring shaft 2. A plurality of feeding holes 7 are formed in the bottom of the feeding ring pipe 6 in the circumferential direction of the feeding ring pipe 6 at equal intervals. In the embodiment, as shown in Figure 2 , the feeding holes 7 are inclined towards the hollow stirring shaft 2, so that the powder can be fed into the middle part of the magnetic core pulping cylinder 1 as much as possible, thereby facilitating the mixing with the slurry.

[0036] The reciprocating lifting mechanism 8 will be described below.

[0037] The reciprocating lifting mechanism 8 is located in the magnetic core pulping cylinder 1 and is used for reciprocating lifting the feeding ring pipe 6 along the axis of the hollow stirring shaft 2. Specifically, the reciprocating lifting mechanism 8 comprises a sliding pipe 801 which slides in the hollow stirring shaft 2, and the lower end of the sliding pipe 801 is closed to prevent the powder from leaking out of the lower end of the sliding pipe 801. A plurality of fixed pipes 802 are connected in communication between the sliding pipe 801 and the feeding ring pipe 6, each fixed pipe 802 is inclined, and the sliding pipe 801 and the feeding ring pipe 6 are fixedly connected and in communication with each other through the inclined fixed pipes 802, which also facilitates the powder to enter the feeding ring pipe 6 through the inclined fixed pipes 802. A strip-shaped hole 9 corresponding to each fixed pipe 802 is formed in the hollow stirring shaft 2, each strip-shaped hole 9 is arranged along the axial direction of the hollow stirring shaft 2, and each fixed pipe 802 moves through the corresponding strip-shaped hole 9 in the horizontal direction. When the sliding pipe 801 slides up and down in the hollow stirring shaft 2, the fixed pipes 802 slide up and down in the strip-shaped holes 9, thereby driving the feeding ring pipe 6 to move up and down in the magnetic core pulping cylinder 1, and the powder can be scattered into different depths.

[0038] It needs to be explained that the upper end of the sliding pipe 801 is connected with the bellows 10 in a conductive way, the upper end of the bellows 10 is connected with the guide pipe 11 in a conductive way, the guide pipe 11 is fixed to the upper end of the hollow stirring shaft 2, the guide pipe 11 can rotate with the hollow stirring shaft 2, when the sliding pipe 801 slides up and down in the hollow stirring shaft 2, the bellows 10 can be driven to contract, so that the sliding pipe 801 and the guide pipe 11 can keep communicating with each other. The rotary joint 12 is fixedly installed on the inner top of the installation shell 3, the rotating part of the rotary joint 12 is connected with the guide pipe 11 in a conductive way, the stationary part of the rotary joint 12 is connected with the feeding pipe 13 in a conductive way, the feeding pipe 13 is connected with the external material pump through a pipeline in a conductive way, when the material pump works, the powder (such as iron oxide, manganese, zinc and other metal oxides or carbonates) enters into the feeding ring pipe 6 in sequence through the feeding pipe 13, the rotary joint 12, the guide pipe 11, the bellows 10, the sliding pipe 801 and the fixed pipe 802, and then enters into the magnetic core pulping cylinder 1 through the feeding hole 7.

[0039] It needs to be supplemented that the reciprocating lifting mechanism 8 further includes an annular sliding chute 803 fixed in the magnetic core pulping cylinder 1, and the sliding rods 804 sliding in the annular sliding chute 803 are fixed on both sides of the feeding ring pipe 6. When the hollow stirring shaft 2 rotates in the magnetic core pulping cylinder 1, the feeding ring pipe 6 can be driven to rotate synchronously through the cooperation of the sliding pipe 801 and the fixed pipe 802, so as to drive the sliding rods 804 to slide in the annular sliding chute 803.

[0040] In the embodiment, the annular sliding chute 803 includes two high line segments and two low line segments arranged alternately, and the inclined line segments are connected between each high line segment and each low line segment. When the sliding rod 804 slides in the high line segment, the feeding ring pipe 6 is located at the highest position; when the sliding rod 804 slides in the low line segment, the feeding ring pipe 6 is located at the lowest position; when the sliding rod 804 slides in the inclined line segment, the feeding ring pipe 6 moves downward or upward; through the cooperation of the sliding rod 804 and the annular sliding chute 803, the feeding ring pipe 6 can be driven to move up and down reciprocatingly in the magnetic core pulping cylinder 1 during the rotation of the hollow stirring shaft 2, so as to be able to pour the powder into different depths, and then facilitate the uniform mixing of the powder and the slurry.

[0041] The working principle is as follows:

[0042] First, add water, dispersant, thickening agent and other liquids into the magnetic core pulping cylinder 1, then start the driving motor 401, through the cooperation of the first bevel gear 402 and the second bevel gear 403, drive the hollow stirring shaft 2 to rotate, so as to stir and mix the slurry in the magnetic core pulping cylinder 1 through the stirring part 5. During the stirring process, the powder (such as iron oxide, manganese, zinc, and other metal oxides or carbonates) is sequentially transported into the feeding ring pipe 6 through the feeding pipe 13, the rotary joint 12, the conduit 11, the corrugated pipe 10, the sliding pipe 801 and the fixed pipe 802 by the external material pump, and finally fed into the magnetic core pulping cylinder 1 through the feeding hole 7. During the feeding process, the hollow stirring shaft 2 continuously rotates, which can drive the feeding ring pipe 6 to rotate synchronously through the cooperation of the sliding pipe 801 and the fixed pipe 802, so as to drive the sliding rod 804 to slide in the annular sliding groove 803, and then under the action of the annular sliding groove 803, the feeding ring pipe 6 moves up and down in the magnetic core pulping cylinder 1, so as to feed the powder into the slurry at different depths, and then facilitate the uniform mixing of the powder and the slurry.
