In addition, as shown in fig. 1, the main body 10 is inclined along the axial direction thereof such that the first end of the main body 10 is higher than the second end of the main body 10, thereby enabling the material to be transferred and guided out when the main body 10 is rotated, so as to ensure the continuity of production. However, the inclination angle of the main body 10 is not particularly limited as long as the above technical effects can be achieved.

In the present embodiment, as shown in fig. 1, the feeding portion includes a feed hopper 111 and a feed pipe 112 which are disposed obliquely so that a first end of the feed pipe 112 communicating with the feed hopper 111 is higher than a second end of the feed pipe 112 communicating with the feed port 101; in addition, the discharging part in the present embodiment includes the discharging pipe 120 formed into a cone-like structure, and the discharging pipe 120 is also inclined so that the first end of the discharging pipe 120 communicating with the main body 10 is higher than the second end of the discharging pipe 120, so that rapid guiding-out can be facilitated, thereby facilitating improvement of the demagnetization efficiency.

It should be further noted that, the sealing member 13 is disposed at the position of the feeding port 101 of the main body 10, and the sealing member 13 may be a sealing ring or other member, so long as the sealing effect between the main body 10 and the feeding portion and the discharging portion can be ensured, so as to avoid material overflow. In this embodiment, as shown in fig. 2, the discharging pipe 120 is connected to the main body 10 through the bearing 14 (may be configured as a rolling bearing) and the connecting member 15, specifically, the connecting member 15 is disposed at the discharging port 102 of the main body 10, and a protruding clamping portion is formed at the position of the discharging port 102 of the main body 10, so as to be capable of being clamped with the bearing 14 correspondingly, and the feeding pipe 112 is also connected to the main body 10 in a similar manner, so that the main body 10 can rotate relative to the discharging portion.

In the present embodiment, the extending direction of the magnetic portion 203 coincides with the axial direction of the main body 10, and a certain inclination angle may be formed with the axial direction of the main body 10, as long as the above-described technical effects can be achieved.

Furthermore, it should be further noted that the second connecting portion 202 in the present embodiment is formed as an external thread corresponding to the internal thread of the first connecting portion 103, so as to enable the detachable connection between the magnetic member 20 and the main body, and further facilitate cleaning or maintenance and replacement of the magnetic member.

In addition, the distribution manner of the first connection portions 103 (i.e., the distribution manner of the magnetic members 20) is not fixed, so long as the sufficient and uniform demagnetization of the magnetic members 20 can be ensured, for example, the plurality of first connection portions 103 in the present embodiment are disposed around the outside of the feed port 101 (as shown in fig. 1 and 3), and the first connection portions 103 are as close as possible to the inner wall of the main body 10, so as to improve the contact probability and contact area between the material and the magnetic portion 203 when the material rotates along with the main body 10; the plurality of first connection parts 103 are spaced uniformly to ensure uniformity of demagnetization.
