Description

Technical Field

[0001] This utility model belongs to the technical field of wet cylindrical permanent magnet separators, specifically relating to a device for adjusting the selection area of ​​a magnetic separator. Background Technology

[0002] Magnetic separators are commonly used in iron ore beneficiation. Our department uses a semi-counter-current magnetic separator. The slurry is fed into the trough from the bottom of the cylinder via a feeder. Magnetic particles are carried to a certain height by the cylinder and fall into the concentrate trough, while non-magnetic particles are carried by the moving slurry in the opposite direction of the cylinder's rotation to the tailings trough. The quality of this separator directly affects the final iron concentrate product. The only adjustable parameters in production are the magnetic separation angle, feed concentration, dispersion water, and discharge water. With economic development and resource depletion, rich ores are becoming increasingly scarce, while lean ores are becoming more abundant. This places higher demands on the equipment's separation capabilities, making it crucial to enhance its operability.

[0003] In view of the above factors, this utility model provides a device for adjusting the selection area of ​​a magnetic separator. By increasing the selection area of ​​the magnetic separation operation, the separation process time is increased, thereby improving the quality of the concentrate. This can extend the selection time of the magnetic separation operation, increase the concentrate yield and quality, and create favorable conditions for subsequent separation operations.

[0006] The positioning mechanism is symmetrically arranged on both sides of the magnetic separator along the length direction of the concentrate end of the magnetic separator, and the positioning mechanism is arranged on both sides of the bottom of the chute at the concentrate end of the magnetic separator.

[0007] The adjustable magnetic separation fixing plate forms a concentrate reserved space with the magnetic separator drum, and the adjustable magnetic separation fixing plate can move along the concentrate end of the magnetic separator toward the magnetic separator drum.

[0008] Furthermore, the adjustable magnetic separation fixing plate is a metal plate structure, and the adjustable magnetic separation fixing plate has symmetrically arranged waist-shaped holes on its wide side to connect with the positioning mechanism.

[0009] Furthermore, the adjustable magnetic separator fixing plate is provided with an inclined end on the side opposite to the magnetic separator.

[0010] Furthermore, the inclined end is an inclined structure formed by folding the adjustable magnetic separation fixing plate along its side length direction into a width of 30mm and an angle of 135°.

[0011] Furthermore, the positioning mechanism includes a positioning plate, on which a positioning bolt sleeve is provided, and a positioning bolt is provided inside the positioning bolt sleeve. The positioning bolt passes through the oblong hole on the adjustable magnetic separation fixing plate and is locked to the end face of the adjustable magnetic separation fixing plate by a nut.

[0012] Furthermore, two sets of positioning bolt sleeves are spaced apart, and the positioning bolt sleeves contact the chute at the concentrate end of the magnetic separator.

[0013] Furthermore, the positioning bolt sleeve is welded onto the chute at the concentrate end of the magnetic separator, and the chute has a channel for the positioning bolt to pass through, the channel cooperating with the slotted hole.

[0014] Furthermore, the positioning bolt is inserted into the positioning bolt sleeve and passes through the chute at the concentrate end of the magnetic separator.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention fixes an adjustable magnetic separation plate to the concentrate discharge end of the magnetic separator. By increasing the fine selection area of ​​the magnetic separation operation, the separation process time is increased, thereby improving the quality of the concentrate.

[0033] The positioning bolt sleeves are symmetrically arranged on the positioning plate and opposite to the waist-shaped hole. The connection between the positioning bolt sleeve 9 and the positioning plate is through. The positioning bolt enters the positioning bolt sleeve 9 at the rear end of the positioning plate. The positioning bolt sleeve 9 is welded to the chute 4 at the concentrate end of the magnetic separator 1. The chute 4 has a channel for the positioning bolt 10 to pass through.
