[0002] The slag produced during the cadmium production process needs to be treated with a magnetic separator for iron removal. The adjustment angle of the permanent magnet barrel of the existing magnetic separator is limited and cannot meet all working conditions. For example, the Chinese patent application with application number CN201220488132.X discloses a magnetic suction adjustment mechanism for a magnetic separator. When the deflection angle of the magnetic system needs to be adjusted, adjusting the position of the nut 4 on the adjustment rod 2 can drive the magnetic system fixed to the support shaft 6 to adjust within the range of +15° to -15°, ensuring that the magnetic system can be adjusted at any time when the magnetic separator is in working condition. Obviously, the existing adjustment mechanism has the following defects:

[0003] 1. It cannot meet the large-angle adjustment of the permanent magnet tube, and the adjustment range is limited, so it cannot meet the use requirements under different working conditions;

[0026] Embodiment: This embodiment provides a permanent magnetic drum adjustment mechanism for a slag magnetic separator, as shown in the attached Figure 1 As shown, it includes an adjustment shaft 1 rotatably mounted on a frame (not shown in the figure), a permanent magnet cylinder 2 fixedly mounted on the adjustment shaft, and a roller 3 rotatably mounted on the adjustment shaft, and the roller is driven by a drive device using a chain drive or a belt drive. This is a prior art and will not be described in detail here. In order to solve the technical problems existing in the existing permanent magnet cylinder adjustment mechanism, this embodiment adopts the following solution:

[0027] As attached Figure 1 As shown, the axial end of the adjustment shaft 1 is fixedly mounted with a fan-shaped plate 4 which is directly opposite to the permanent magnetic tube 2 and has the same arc as the permanent magnetic tube 2. This design allows the position of the fan-shaped plate to represent the relative position of the permanent magnetic tube, thus realizing the visual adjustment of the permanent magnetic tube. The fan-shaped plate 4 is hinged with a connecting rod 5, and the connecting rod 5 is hingedly connected to the slider 6.3 of the screw adjustment device 6. This design allows the fan-shaped plate, the connecting rod and the slider to form a crank slider mechanism. The fan-shaped plate constitutes a crank. By changing the position of the slider, the fan-shaped plate can be adjusted 360°, thereby realizing the adjustment of the permanent magnetic tube 360°. The position of the slider is controlled by the screw. The angle adjustment of the permanent magnetic tube can be achieved by simply rotating the screw, and the adjustment operation is simple.

[0028] Preferably, as attached Figure 1 As shown, the screw adjustment device 6 of this embodiment includes a base 6.1, a screw 6.2, a slider 6.3 and a handwheel 6.4, wherein the base 6.1 is fixed on a frame, a slide rail 6.1.1 is provided on the base 6.1, the slider 6.3 is slidably mounted on the slide rail 6.1.1, the screw 6.2 is rotatably mounted on the base 6.1, and the screw 6.2 is screwed to the slider 6.3, and the handwheel 6.4 is arranged at the end of the screw 6.2. In this embodiment, the position of the slider can be controlled by rotating the handwheel, and then the position of the fan-shaped plate can be controlled, and the position of the fan-shaped plate represents the relative position of the permanent magnetic cylinder. In other embodiments, the handwheel can be replaced by a stepping motor to realize automatic adjustment.

[0029] Further, as attached Figure 1 and attached Figure 2 As shown, the screw adjustment device 6 of this embodiment also includes a locking assembly, which includes a gear 6.5 arranged on the screw, a mounting plate 6.6 arranged on the base, and a knob plunger pin 6.7 arranged on the mounting plate. The bottom of the pin rod of the knob plunger pin 6.7 is set as a tooth 6.7.1, which is used to insert into the tooth groove of the gear 6.5. The setting of the locking assembly of this embodiment is used to lock the position of the permanent magnet cylinder after adjustment. In specific operation, when the position of the permanent magnet cylinder needs to be adjusted, the knob plunger pin is pulled out and rotated to a certain angle so that the tooth on the pin rod is disengaged from the gear and maintains the position. After adjusting the position, the knob plunger pin is reset, and the tooth on the pin rod is inserted into the tooth groove to ensure the position of the screw.

[0030] Preferably, as attached Figure 1 As shown, the fan-shaped plate 4 of this embodiment is a hollow fan-shaped plate, and the hollow structure design saves materials and reduces costs. Preferably, the hinge hole is set at the center line of the fan-shaped plate 4 near its arc edge.

[0031] Preferably, in this embodiment, sector plates 4 are provided at both ends of the adjusting shaft 4, and the two sector plates 4 are connected to the screw adjusting device 6 through a connecting rod 5. By providing the adjusting mechanism at both ends of the adjusting shaft, the force is more evenly applied, thereby increasing the service life of the adjusting mechanism.
