[0025] The following provides specific embodiments of the present invention with reference to the accompanying drawings to further illustrate the structure of the present invention.

[0026] Example 1. Figure 1-3 The novel high-frequency oscillation beneficiation device shown in the figure comprises a rectangular frame 1, a trough body 3, a bracket 5, and a vibrator 6. A corrugated bottom plate 4 is installed at the bottom of the trough body 3, one end of the corrugated bottom plate 4 extends out of the trough body 3, a material cutter 7 is installed in the middle of each corrugation of the corrugated bottom plate 4, and a discharge valve 8 is installed at the lowest point of each corrugation of the corrugated bottom plate 4. A bracket 5 is installed at the upper end of the trough body 3, and a vibrator 6 is installed on the bracket 5. The upper part of the trough body 3 is a feed port, and the end of the corrugated bottom plate 4 extending out of the trough body 3 is a discharge port. The provision of the discharge valve 8 facilitates equipment maintenance and cleaning.

[0027] In order to prevent the rectangular frame 1 from vibrating excessively, mounting brackets 3-1 are installed around the trough body 3, and a spring shock-absorbing device 2 is installed above the rectangular frame 1; the spring shock-absorbing device 2 includes four columns 2-1 installed on the rectangular frame 1, and a shock-absorbing spring 2-2 is installed above each of the columns 2-1, and a bracket 2-3 is installed above the shock-absorbing spring 2-2, and a mounting bracket 3-1 is installed above the bracket 2-3; the spring shock-absorbing device 2 supports the trough body 3;

[0028] In order to keep a certain amount of water in the tank, the corrugated bottom plate 4 is designed to discharge at a climbing angle. The climbing angle of the corrugated bottom plate 4 can be determined according to the size and specific gravity of the ore sand particles, and is generally maintained at 5 to 20 degrees with the horizontal plane. The corrugated bottom plate 4 is composed of a plurality of triangular waveforms composed of a down-inclined plate 4-1 and an up-inclined plate 4-2. The angle between the down-inclined plate 4-1 and the up-inclined plate 4-2 is 50 to 120 degrees. The climbing angle refers to the angle between the up-inclined plate 4-2 and the horizontal plane.

[0029] A fixed adjustment device 9 for adjusting the position of the cutter 7 is installed between the cutter 7 and the corrugated bottom plate 4. The fixed adjustment device includes a support rod 9-1 respectively installed on the lower inclined plate 4-1 and the upper inclined plate 4-2. A nut 9-2 is installed on one side of the support rod 9-1. A screw rod 9-3 is installed on the cutter 7. The screw rod 9-3 cooperates with the nut 9-2 to adjust the upper and lower positions of the cutter 7 on the corrugated bottom plate 4. The size of the cut-off opening can be adjusted according to the proportion of mineral concentrate in the material. Figure 4 As shown;

[0030] In order to adjust the vibration frequency according to the coarseness and specific gravity of the material particles and improve the recovery rate and processing volume, the vibrator 6 is installed with an automatic frequency regulator.

[0031] like Figure 5 A novel high-frequency oscillation beneficiation method is shown, comprising the following steps:

[0032] The ore slurry is injected from the upper end of the trough body 3 and flows to the corrugated bottom plate 4. The high-frequency oscillation wave generated by the vibrator 6 oscillates the ore slurry on the corrugated bottom plate 4. Under the action of the oscillation wave and the buoyancy of water, the ore slurry utilizes the difference in specific gravity between different minerals to sink the heavy minerals to the bottom tip of the corrugated bottom plate 4 and float the light minerals to the top, thereby playing a role in separation. As the ore slurry is continuously injected, the later injected material continuously squeezes the previous material on the corrugated bottom plate 4 toward the discharge port. The heavy minerals sunk at the bottom tip of the corrugated bottom plate 4 are intercepted by the cutter 7 on the way to the discharge port and discharged first as mineral concentrate products. The remaining slurries are further squeezed on the corrugated bottom plate to the discharge port and discharged as tailings.

[0033] The ore slurry is a mixture of water and ore sand, and the mass ratio of water to ore sand is 1-2:1;

[0034] The diameter of the ore sand particles in the ore slurry is 0.1-3 mm. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0035] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
