Description

Technical Field

[0003] The invention relates to an adjustment device, in particular to an adjustment device for the inner wall of a magnetic cylinder and the gap between a magnetic system of a permanent magnetic cylinder type magnetic separator, that is, a mechanism is used to adjust the inner wall of the magnetic cylinder and the gap between the magnetic system, thereby adjusting the magnetic field strength of the magnetic separator. Background Art

[0005] Magnetic separator is a kind of mineral processing equipment widely used in magnetic mineral separation. In the actual use of magnetic separator, it is often necessary to adjust the size of its magnetic field; the gap between the inner wall of the magnetic cylinder and the magnetic system of the magnetic separator has a direct impact on the strength of the magnetic field of the magnetic separator. It is difficult to adjust the gap without disassembling the whole machine, which is inconvenient to adjust the gap.

[0006] Therefore, providing a convenient magnetic field strength adjustment device for a magnetic separator is an issue that needs to be urgently addressed by those skilled in the art. Summary of the invention

[0008] In view of this, the present invention provides a permanent magnet drum magnetic separator with adjustable magnetic field strength. Without disassembling the entire magnetic separator, the gap between the inner wall of the drum and the magnetic system bottom plate can be adjusted, thereby adjusting the magnetic field strength of the magnetic separator.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] A permanent magnetic drum type magnetic separator with adjustable magnetic field strength, comprising a magnetic system, a motor, a reducer, a synchronous belt, and also comprising:

[0011] A main shaft, the main shaft comprising, from left to right, a gap adjusting section connected to a left gap adjusting device, a magnetic system fixing section, and a right gap adjusting section connected to a right gap adjusting device;

[0012] The gap adjusting device includes a gap adjusting handle, a screw, a locking nut, a gap adjusting sleeve and a slider mechanism. The gap adjusting handle is connected to the slider mechanism through the screw, the gap adjusting sleeve is matched with the main shaft clearance, the locking nut is used to fix the gap adjusting device, the slider mechanism includes a slider and a guide rail, the slider is connected to the gap adjusting sleeve, and is used to adjust the gap between the main shaft and the sleeve; the gap adjusting device includes two left and right parts, which are distributed on both sides of the main shaft, and the gap is adjusted equidistantly at the same time to ensure the stable rotation of the cylinder.

[0013] The synchronous belt and the reducer are fixed to the frame by bolts. The position of the reducer on the frame can be adjusted to adjust the tightness of the synchronous belt, so that the tightness of the synchronous belt will not be changed before and after the cylinder gap is adjusted.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

[0015] By utilizing the relative movement of the gap adjusting sleeve and the main shaft, the gap between the inner wall of the cylinder and the magnetic system can be changed. By utilizing the spiral pair of the screw and the top support, the gap distance between the gap adjusting sleeve and the main shaft can be controllably adjusted. This enables the adjustment of the gap between the inner wall of the cylinder and the bottom plate of the magnetic system without disassembling the entire magnetic separator, and the adjustment of the magnetic field strength of the magnetic separator, thereby improving convenience.

[0016] Furthermore, the reducer is fixed to the frame by four bolts, and the position of the reducer on the frame can be adjusted by loosening the bolts.

[0017] Furthermore, the gap adjusting device is horizontally fixed on the support by bolts.

[0018] Furthermore, the rotating handle is connected to the screw rod, the screw rod is spirally connected to the top support, the slider is fixed on the screw rod, and the locking nut fixes the movement of the screw rod and the top support, thereby fixing the up and down movement of the slider.

[0019] Furthermore, the magnetic system is fixed in a horizontal working position, and a counterweight in the horizontal direction is used to keep the center of gravity stable.

[0020] Furthermore, the gap adjusting device adjusts the gap between the magnetic system and the cylinder at the left and right sides of the main shaft at the same time.

[0021] Furthermore, the clearance-adjusting sleeve and the main shaft are clearance-matched, and the clearance-adjusting sleeve can only move in the horizontal direction.

[0022] The present invention converts the invisible and unmeasurable gap into a controllable handle rotation, so that the operator can adjust the gap between the inner wall of the cylinder and the magnetic system bottom plate without disassembling the entire magnetic separator, thereby changing the magnetic field strength of the magnetic separator.
