[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0030] As shown in Figures 1-5 the embodiments of the present application disclose a gap adjustment device for a magnetic separator, which comprises a magnetic system 1 of the magnetic separator, an eccentric shaft 2, a jacket 3, a ratchet mechanism 4, a compression assembly 5 and a handle 6. The eccentric shaft 2 comprises a first transmission shaft section 21, an eccentric shaft section 22 and a second transmission shaft section 23 connected in sequence from left to right. The jacket 3 is sleeved on the eccentric shaft section 22 and rotationally connected thereto. The magnetic system 1 is fixed on the jacket 3. The ratchet mechanism 4 comprises a ratchet 41 and a pawl 42. The ratchet 41 is fixedly sleeved on the second transmission shaft section 23. The pawl 42 is installed on the side surface of the jacket 3 through a pin 43 and corresponds to the position of the ratchet 41. The pawl 42 can rotate around the axis of the pin 43. The compression assembly 5 comprises a spring mounting base 51 and a spring 52. The spring mounting base 51 is fixed on the side surface of the jacket 3. The spring 52 is installed in the spring mounting base 51 and its extended end abuts on the pawl 42, so that the pawl 42 is pressed on the ratchet teeth of the ratchet 41, ensuring that the ratchet 41 does not reverse. The handle 6 is fixedly sleeved on the first transmission shaft section 21. The relative rotation of the eccentric shaft section 22 and the jacket 3 can change the distance between the inner wall of the cylinder 7 and the magnetic system 1. The cooperation of the ratchet mechanism 4 and the compression assembly 5 limits each rotation position of the eccentric shaft 2, thereby fixing the position of the magnetic system 1, so that the adjustment of the gap between the inner wall of the cylinder 7 and the bottom plate of the magnetic system 1 can be completed without disassembling the whole magnetic separator, improving the convenience.

[0031] Specifically, a wear-resistant bushing 8 is installed between the eccentric shaft section 22 and the jacket 3, wherein the eccentric shaft section 22 and the wear-resistant bushing 8 are in clearance fit.

[0032] Specifically, the sleeve 3 includes an upper arc-shaped clamping plate 31 and a lower arc-shaped clamping plate 32, which are connected together by bolts and nuts to fasten onto the wear-resistant bushing 8 (in contact); the pawl 42 is mounted on the side of the upper arc-shaped clamping plate 31 by a pin 43; the spring mounting base 51 is fixed on the side of the upper arc-shaped clamping plate 31; and the magnetic system 1 is fixed on the lower arc-shaped clamping plate 32.

[0033] Specifically, the magnetic system 1 includes a central magnetic yoke 11 and a permanent magnet 12. The central magnetic yoke 11 is fixed to the lower arc-shaped clamping plate 32 by a support plate 13, and the permanent magnet 12 is fixed to the central magnetic yoke 11. In this embodiment, the fixing is done by welding.

[0034] Specifically, the ratchet 41 is fixedly connected to the second drive shaft section 23 via the hook wedge 44.

[0035] Of course, in order to fix the position of the handle 6, and thus fix the eccentric shaft 2 and the magnetic system 1, a fixing bolt 9 is also installed at the end of the handle 6. The end of the handle 6 can be fastened to the magnetic separator frame through the fixing bolt 9.

[0036] To further optimize the technical solution of the present invention, a scale 10 is also included. The scale 10 is set on the frame of the magnetic separator and distributed circumferentially along the central magnetic yoke 11, thereby transforming the invisible and unmeasurable gap into a visible scale 10 and improving the gap adjustment accuracy.

[0037] Working principle of the invention:

[0038] Gap adjustment: such as Figure 4 As shown, before the magnetic separator is started, the jacket 3 and the magnetic system 1 are kept vertically downward due to their own weight, and the magnetic separator cylinder 7 remains stationary. At this time, the handle 6 is rotated clockwise to drive the eccentric shaft 2 to rotate. By utilizing the relative rotation between the eccentric shaft section 22 and the jacket 3, the magnetic system 1 moves up and down vertically along the axis of the eccentric shaft 2 to adjust the gap between the inner wall of the cylinder 7 and the bottom of the magnetic system 1.

[0039] Magnetic system fixed: such as Figure 5 As shown, after the gap adjustment is completed, rotate the handle 6 counterclockwise by 90° to reach the required working position. Because the pawl 42 is engaged with the ratchet 41, it drives the sleeve 3 and the magnetic system 1 to rotate counterclockwise as a whole. Then, fix the position of the handle 6 with the fixing bolt 9, thereby fixing the eccentric shaft 2, the sleeve 3 and the magnetic system 1 as a whole, completing the entire gap adjustment process. Finally, start the machine, and the magnetic separator begins the sorting work.
