Description

Technical Field

[0001] The invention relates to the technical field of magnetic separators, in particular to a feeding device for a magnetic separator which is convenient for even distribution of materials. Background Art

[0002] Magnetic separator is a screening equipment used to remove iron powder and other materials from recycled powdery particles. After the slurry flows into the trough through the feed box, the ore particles enter the feeding area of ​​the trough in a loose state under the action of the water flow of the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the cylinder rotates. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic lotus" finally adsorbed on the surface of the cylinder are concentrates. Magnetic separators are widely used in resource recovery, wood industry, mining industry, kiln industry, chemical industry, food industry and other factories.

[0003] Announcement No. CN217349689U discloses a feeding device for a magnetic separator. A transmission assembly is movably installed on the top of the lifting plate. The output end of the forward and reverse motor can be used to drive the threaded rod to rotate. The rotation of the threaded rod drives the moving block to move. The movement of the moving block drives the transmission block to move. The movement of the transmission block drives the movable rod to move. The movement of the movable rod cooperates with the movable shaft to drive the material box to tilt at a certain angle, so that the raw ore in the material box can fall on the belt conveyor through the discharge port. The forward and reverse rotation of the forward and reverse motors can be controlled by a controller, which can drive the material box to repeatedly dump the raw ore in the material box regularly. The purpose of preventing the raw ore from piling up is achieved, which solves the traditional need to convey the crushed raw ore to the top of the magnetic separator by a belt conveyor. However, during the conveying process of the belt conveyor, the crushed raw ore is easily concentrated on the conveyor belt. With the conveying of the belt conveyor, the raw materials accumulated on the conveyor belt fall on the magnetic separation drum, which reduces the screening effect of the magnetic separation drum. However, the following problems still exist in the actual use of this patent: Although the feeding device of the magnetic separator controls the forward and reverse rotation of the forward and reverse motors through a controller, which can drive the material box to repeatedly dump the material box so that the raw ore in the material box can fall regularly on the belt conveyor, thereby achieving the purpose of preventing the raw ore from piling up, but the repeated dumping operation of the material box will cause the ore to be discharged unevenly, so that the ore cannot be evenly dumped on the magnetic separator, thereby affecting the magnetic separation effect of the magnetic separator. At the same time, the concentration of the ore cannot be controlled, which is not conducive to improving the magnetic separation efficiency of the magnetic separator.

[0004] Therefore, a feeding device for a magnetic separator that facilitates uniform material distribution is proposed to solve the problems mentioned above. Summary of the Invention

At the same time, under the pushing action of the ore, the reciprocating movement of the inclined shovel is realized, which is convenient for shoveling the ore, shoveling the large-particle-size ore, and conveying the small-particle-size ore through the through groove. By starting the second rotating motor to drive the second rotating worm to rotate, using the characteristic of the meshing connection between the second rotating worm and the second rotating worm wheel, the second rotating worm wheel drives the grinding block to rotate, so as to realize the grinding function of the ore. The specific content is as follows: 1. By setting up a uniform feeding mechanism, not only can the conveyor motor drive the sprocket drive assembly and the conveyor rollers to rotate, and utilize the transmission connection between the conveyor rollers and the conveyor belt to realize the rotation of the conveyor belt, thereby performing the function of conveying ore materials, but also, by virtue of the feature that the cleaning scraper is attached to the surface of the conveyor belt, the cleaning of the ore materials on the surface of the conveyor belt can be achieved, avoiding the phenomenon of ore material residue waste. The ore materials are dispersed by the dispersion rods inside the dispersion bracket to prevent the phenomenon of ore material agglomeration. At the same time, the vibration motor drives the vibration rotating rod and the vibration cam to rotate. Under the action of the limit bracket, the sliding of the limit sliding rod can be realized, driving the inclined shovel to move. Meanwhile, under the pushing action of the ore materials, the reciprocating motion of the inclined shovel is achieved, facilitating the shoveling of the ore materials. The large-particle-size ore materials are shoveled up, and the small-particle-size ore materials are conveyed through the through slots. The large ore materials move towards the waste discharge port through the inclined surface of the inclined shovel and are finally discharged.

Using the transmission connection between the conveying roller 104 and the conveyor belt 105, the rotation of the conveyor belt 105 is realized, so as to carry out the conveying function of the ore. Using the characteristic that the cleaning scraper 106 is attached to the surface of the conveyor belt 105, the ore on the surface of the conveyor belt 105 can be cleaned to avoid the phenomenon of ore residue waste. The ore is broken up by the breaking rod 108 inside the breaking support 107 to avoid the phenomenon of ore agglomeration. At the same time, the vibration motor 109 is used to drive the vibration rotating rod 110 and the vibration cam 111 to rotate. Under the action of the limit support 112, the sliding of the limit sliding rod 113 can be realized, and the inclined shovel 114 is driven to move. At the same time, under the pushing action of the ore, the reciprocating movement of the inclined shovel 114 is realized, which is convenient for shoveling the ore. The large-particle-size ore is shoveled up, and the small-particle-size ore is conveyed through the through groove 115. The large ore moves to the waste discharge port 116 through the inclined surface of the inclined shovel 114 and is finally discharged. At the same time, when the large-particle-size ore adheres to the small-particle-size ore and moves, the breaking effect is realized through the reciprocating movement of the inclined shovel 114, avoiding the phenomenon that the small-particle-size ore is discharged, thus affecting the ore screening effect.

[0026] Finally, the limiting baffle 119 can be used to limit the ore. According to the sparse and viscous degree of the ore, the conveying roller 104 with a limiting rubber strip can be selected, so as to effectively avoid the phenomenon of ore flowing. The first rotating motor 122 drives the first rotating worm 123 to rotate. By using the meshing connection between the first rotating worm 123 and the first rotating worm wheel 124, the rotation of the adjusting disc 125 can be realized. The adjusting knob 126 drives the adjusting threaded rod 127 to rotate, so that the adjusting threaded sleeve 128 drives the reciprocating slider 129 to move, which can change the rotation radius of the reciprocating slider 129, and thus change the reciprocating amplitude of the reciprocating bracket 130. The reciprocating rotating sleeve 131 drives the reciprocating spray head 132 to reciprocate, so as to realize the uniform feeding of the ore and improve the magnetic separation effect of the magnetic separator.
