Description

Technical Field

[0001] The invention relates to the technical field of magnetic separators, in particular to a magnetic separator feeding device 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 powdered 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 in the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically gathered 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 when the cylinder rotates due to the alternating magnetic poles. Non-magnetic minerals such as gangue and other non-magnetic minerals entrained in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic chains" that are finally adsorbed on the surface of the cylinder are the concentrate. Magnetic separator is widely used in resource recovery, wood industry, mining industry, kiln industry, chemical industry, food industry and other factories.

[0003] Announcement No. CN217349689U discloses a magnetic separator feeding device. 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 onto the belt conveyor through the discharge port. The forward and reverse rotation of the forward and reverse motors can be controlled by a controller to drive the material box to repeatedly dump the raw ore, so that the raw ore in the material box can fall regularly on the belt conveyor, thereby achieving the purpose of preventing the accumulation of raw ore. This solves the traditional problem of needing to use a belt conveyor to transport the crushed raw ore to the top of the magnetic separator. However, during the transportation process of the belt conveyor, the crushed raw ore is easily accumulated on the conveyor belt. As the belt conveyor is transported, the raw materials accumulated on the conveyor belt fall onto the magnetic separation drum, reducing the screening effect of the magnetic separation drum. However, this patent still has the following problems during actual use:

[0004] 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 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, 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.

[0005] Therefore, a magnetic separator feeding device that is convenient for even distribution of materials is proposed to solve the above-mentioned problems. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the magnetic separator feeding device that is convenient for uniform material distribution utilizes a vibration motor to drive the vibration rotating rod and the vibration cam to rotate, and under the action of the limit bracket, the limit sliding rod can be slid and the inclined shovel can be driven to move. At the same time, under the pushing action of the mineral material, the inclined shovel can be reciprocated, which is convenient for scooping up the mineral material, scooping up the mineral material with large particle size, and transporting the mineral material with small particle size through the through trough. By starting the second rotating motor to drive the second rotating worm to rotate, the second rotating worm and the second rotating worm wheel are engaged with each other, so that the second rotating worm wheel drives the grinding block to rotate, thereby realizing the grinding function of the mineral material. The specific contents are as follows:

[0022] 1. By setting up a uniform feeding mechanism, not only can the conveying motor be used to drive the sprocket transmission assembly and the conveying roller to rotate, but the transmission connection between the conveying roller and the conveyor belt can be used to realize the rotation of the conveyor belt, thereby performing the function of conveying the ore. The cleaning scraper is connected to the surface of the conveyor belt to clean the ore on the surface of the conveyor belt, thereby avoiding the phenomenon of residual waste of ore. The ore is broken up by the breaking rod inside the breaking bracket to avoid the phenomenon of ore agglomeration. At the same time, the vibration motor is used to drive 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, and the tilting shovel is driven to move. At the same time, under the pushing action of the ore, the reciprocating motion of the tilting shovel is realized, which is convenient for scooping up the ore, scooping up the large-size ore, and conveying the small-size ore through the through chute. The large ore is moved to the waste outlet through the inclined surface of the tilting shovel. The ore is finally discharged. At the same time, when the large-size ore material adheres to the small-size ore material and moves, the reciprocating motion of the inclined shovel is used to break it up, so as to avoid the small-size ore material being discharged, thereby affecting the ore screening effect. The limit baffle can be used to limit the ore material. According to the sparseness and viscosity of the ore material, a conveying roller with a limiting rubber strip can be selected to effectively avoid the flow of the ore material. The first rotating motor drives the first rotating worm to rotate, and the meshing connection between the first rotating worm and the first rotating worm gear is used to realize the rotation of the adjusting disk. The adjusting knob drives the adjusting threaded rod to rotate, so that the adjusting threaded sleeve drives the reciprocating slider to move, which can change the rotation radius of the reciprocating slider, thereby changing the reciprocating amplitude of the reciprocating bracket, and the reciprocating rotating sleeve drives the reciprocating nozzle to move back and forth, so as to achieve uniform feeding of the ore material, which can improve the magnetic separation effect of the magnetic separator;

[0023] 2. By setting up the grinding and mixing mechanism, not only can the electric lifting rod be used to drive the support plate and the grinding block to move up and down, but also the distance between the grinding block and the inner wall of the grinding box can be adjusted to change the particle size of the ground mineral material, thereby adapting to magnetic separators of different specifications. By starting the second rotating motor to drive the second rotating worm to rotate, the second rotating worm and the second rotating worm wheel are engaged, so that the second rotating worm wheel drives the grinding block to rotate, thereby realizing the grinding function of the mineral material. Water can be added to the mixing drum through the water inlet valve to achieve dilution and stirring of the mineral material. The concentration of the ore can be detected by the slurry concentration meter. By controlling the concentration of the ore, the magnetic separation effect of the magnetic separator can be improved. By starting the mixing motor to drive the driving gear to rotate, and utilizing the characteristics of the meshing connection between the driving gear, the driven gear and the meshing gear plate, not only can the driven gear drive the rotating disk and the mixing rod to rotate, but the driving gear also drives the mixing auger and the mixing bracket to rotate, thereby achieving sufficient mixing of the ore. The mixing bracket drives the spiral cleaning blade to rotate, which can clean the inner wall of the mixing barrel and avoid the phenomenon of residual waste of ore.

The mineral material is broken up by the breaking rod 108 inside the breaking bracket 107 to avoid the phenomenon of mineral material agglomeration. At the same time, the vibration motor 109 is used to drive the vibration rotating rod 110 and the vibration cam 1 11 rotates, and under the action of the limiting bracket 112, the limiting sliding rod 113 can slide, and the inclined shovel 114 is driven to move. At the same time, under the pushing action of the mineral material, the reciprocating motion of the inclined shovel 114 is realized, which is convenient for scooping up the mineral material, scooping up the large-particle mineral material, and transporting the small-particle mineral material through the through groove 115. The large mineral material moves to the waste outlet 116 through the inclined surface of the inclined shovel 114, and is finally discharged. At the same time, when the large-particle mineral material adheres to the small-particle mineral material when moving, the reciprocating motion of the inclined shovel 114 is used to achieve the effect of breaking up the small-particle mineral material, avoiding the phenomenon of small-particle mineral material being discharged, thereby affecting the effect of mineral screening.

[0045] Finally, the limiting baffle 119 can be used to limit the mineral material. According to the sparseness and viscosity of the mineral material, the conveying roller 104 with a limiting rubber strip can be selected to effectively avoid the flow of the mineral material. The first rotating motor 122 drives the first rotating worm 123 to rotate. The meshing connection between the first rotating worm 123 and the first rotating worm wheel 124 is used to realize the rotation of the adjusting disk 125. 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, thereby changing the reciprocating amplitude of the reciprocating bracket 130, and the reciprocating rotating sleeve 131 drives the reciprocating nozzle 132 to move back and forth, thereby realizing uniform discharge of the mineral material and improving the magnetic separation effect of the magnetic separator.
