[0024] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following embodiments of the present invention will be described in conjunction with the accompanying drawings.

[0025] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a self-cleaning permanent magnet cylinder, including a cylinder body and a cleaning kit, wherein the cylinder body includes an inner cylinder 01 and an outer cylinder 02, and a spiral plate 03 is arranged inside the inner cylinder 01 along the central axis; a spiral shaft 04 is provided at the center of the spiral plate 03, and a transmission device is connected above the spiral shaft 04, and a circle of electromagnets 05 is provided around the inner cylinder 01, and the electromagnets 05 are close to the outer wall of the inner cylinder 01, and the electromagnets 05 are connected to the power supply 06, and the motor 18 and the power supply 06 are both located between the inner cylinder 01 and the outer cylinder 02, and the cleaning kit includes a fixed ring 07, a fixed rod 08, a scraper 09 and a rotating shaft 10, and the rotating shaft 10 is sleeved on the spiral shaft 10, one end of the fixed rod 08 is connected to the rotating shaft 10, and the other end is connected to the scraper 09, and the scraper 09 is close to the inner wall of the inner cylinder 01, and the fixed ring 07 is connected to the outside of the fixed rod 08.

[0026] As a preferred structure, Figure 1 As shown, the side wall of the outer cylinder 02 is hinged with an inspection door 11. The design of the inspection door 11 generally takes ergonomics into consideration so that the operator can easily open and close it. The inspection door 11 facilitates the inspection and replacement of the permanent magnet cylinder.

[0027] In a specific embodiment of the present invention, Figure 1 As shown, the upper opening of the cylinder is the feed port 12, and the bottom opening is the discharge port 13. After the feed enters the feed port 12, it enters the spiral plate 03 and is driven by the spiral plate 03 to fully contact the magnetic field in the inner cylinder 01, thereby improving the iron removal effect.

[0028] During specific assembly, the rotating shaft 10 of the cleaning kit is magnetically connected to the spiral rod, and the connection can be manually controlled when necessary. When the machine is working, the scraper 09 does not operate; when cleaning is required, the discharge port 13 is opened to connect the rotating shaft 10 to the spiral rod, and the motor 18 is turned on to drive the scraper 09 to clean the surface of the inner cylinder 01.
