Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing, and specifically to an ore crushing device based on electro-explosion of metal wires. Background Art

[0002] Shock wave ore crushing technology is an efficient physical method for crushing ores using high-energy shock waves. Its core principle is to cause stress concentration inside the ore by the shock wave energy released instantaneously, resulting in the expansion of mineral grain boundaries or internal fissures, thereby achieving selective crushing. This technology can be divided into two categories: mechanical shock waves (such as high-pressure gas-driven pistons) and electromagnetic pulse shock waves (generating plasma expansion through capacitor discharge). It has the advantages of low energy consumption, less dust, and low crushing rate, and is especially suitable for pre-selection and waste rejection of high-hardness minerals or ores containing rare metals.

[0003] During the ore crushing process, it is not necessary to pursue complete crushing in all cases. Instead, the ore needs to be crushed to a specific particle size range according to the requirements of subsequent ore dressing processes. Over-crushing will not only cause energy waste, but also have a series of adverse effects on the ore dressing process. Over-crushing will lead to excessive mixing of valuable minerals and gangue minerals, increasing the difficulty of mineral dissociation and reducing the separation efficiency. In processes such as gravity separation and magnetic separation, overly fine mineral particles are easily lost with the tailings, resulting in a decrease in metal recovery rate. In addition, over-crushing will significantly increase the energy consumption and steel consumption in the grinding process, increasing production costs. Summary of the Invention

[0037] As Figures 1 - 10 shown, the present invention provides a technical solution: a ore crushing device based on electro-explosion of metal wire, including a box body 1 and a frame 2 fixedly connected to the outer surface of the box body 1;

[0038] A shock wave device 4 for crushing the ore in the inner cavity of the box body 1, and a top cover 3 arranged on the lower surface of the shock wave device 4. By setting the shock wave device 4, the opening of the box body 1 can be opened, so as to facilitate placing the ore to be broken in the inner cavity of the box body 1, and then closing the opening of the box body 1. After that, shock waves can be generated in the inner cavity of the box body 1, and then the crushing work of the ore in the inner cavity of the box body 1 can be completed;

[0039] A stirring mechanism 5 for stirring the ore in the inner cavity of the box body 1. By setting the stirring mechanism 5, when the shock wave device 4 emits shock waves into the inner cavity of the box body 1 and causes an explosion in the inner cavity of the box body 1, the force generated by the explosion can be used to stir the ore in the inner cavity of the box body 1, and during the stirring process, the ore crushed to a certain extent can be discharged;

[0043] The shock wave device 4 includes a limit frame 41 which is fixedly connected to the upper surface of the top cover 3. The outer surface of the limit frame 41 is rotatably connected with a rotating frame 42. The end of the rotating frame 42 is fixedly connected with an arc-shaped cover 43. The arc-shaped cover 43 is made of metal and the cross-section of its inner cavity is parabolic. A sealing ring 7 is fixedly connected to the upper surface of the top cover 3. The sealing ring 7 is in extrusion fit with the outer surface of the arc-shaped cover 43. By providing the arc-shaped cover 43, the shock wave generated by the explosion of the metal wire can be guided so that the shock wave can be transmitted to the surface of the ore. By providing the sealing ring 7, it can cooperate with the arc-shaped cover 43 to make there be no gap between the arc-shaped cover 43 and the top cover 3, thereby preventing air from escaping. By providing the limit frame 41, the rotating frame 42 can be limited so that the rotating frame 42 can drive the arc-shaped cover 43 to rotate. The outer surface of the arc-shaped cover 43 is fixedly connected with a first support rod 44. The end of the first support rod 44 is fixedly connected with a first threaded ring 45. A threaded rod 46 is threadedly connected to the inner cavity of the first threaded ring 45. The bottom end of the threaded rod 46 is threadedly connected with a second threaded ring 47.

An insulating tube 493 is fixedly connected to the inner wall of the connecting frame 492. The number of the insulating tubes 493 is two, and the two insulating tubes 493 are symmetrically and fixedly connected to the inner wall of the connecting frame 492.

The first wire 496 and the second wire 497 are respectively fixedly connected to the positive and negative electrodes of an external high-voltage power supply. When the high-voltage power supply works, a high-voltage current is made to form a closed circuit through the first wire 496 and the second wire 497. By arranging the insulating tube 493, it is possible to prevent the current passing through the positive diode 494 and the negative diode 495 from leaking out and causing a short circuit in the circuit. By arranging the first wire 496 and the second wire 497, the positive diode 494 and the negative diode 495 can be respectively connected to the positive and negative electrodes of the high-voltage power supply. Then, when the high-voltage power supply works, the load wire 498 is connected to the circuit. Then, under the action of the continuous high-voltage current, the load wire 498 generates an explosion, and then a shock wave is generated.

[0045] The stirring mechanism 5 includes a reflection ring 51 and a material screening frame 56. The reflection ring 51 is made of metal. The reflection ring 51 is slidably connected to the inner cavity of the box body 1. A fixing block 52 is fixedly connected to the upper surface of the reflection ring 51. A first spring 53 is fixedly connected to the upper surface of the fixing block 52. The top end of the first spring 53 is fixedly connected to the top surface of the inner cavity of the top cover 3. The material screening frame 56 is fixedly connected to the inner wall of the box body 1. A reflection cone barrel 57 is fixedly connected to the upper surface of the material screening frame 56. The reflection cone barrel 57 is made of metal. By providing the reflection ring 51 and the reflection cone barrel 57, they can cooperate with the arc-shaped cover 43 so that the shock wave generated by the explosion of the load wire 498 can be reflected by the arc-shaped cover 43 to the outer surface of the reflection cone barrel 57, and then reflected to the inner ring of the reflection ring 51, and then reflected by the reflection ring 51 onto the ore on the upper surface of the material screening frame 56, making the shock wave evenly reflected on the ore. By providing the first spring 53, it can support the reflection ring 51. A track groove 8 is provided on the inner wall of the box body 1.

A second spring 66 is fixedly connected to the side of the first piston plate 62 away from the third support rod 64. The end of the second spring 66 is fixedly connected to the inner wall of the first limiting tube 61. By providing the first limiting tube 61, the first piston plate 62 can be limited, so that the first piston plate 62 can move horizontally in the inner cavity of the first limiting tube 61. When the gas in the inner cavity of the box body 1 expands due to the generation of shock waves, the first piston plate 62 is pressured to move, thereby driving the third support rod 64 and the extrusion column 65 to move horizontally, and then enabling the extrusion column 65 to extrude the second support rod 58, ultimately causing the stirring plate 59 to move downward. By providing the second spring 66, the first piston plate 62 can rebound to its original position after moving.

[0047] The outer side of the discharge pipe 612 is penetrated by a third limiting pipe 613. A rotating column 614 is rotatably connected to the inner cavity of the third limiting pipe 613.

By providing the hydraulic motor 622, after the shock wave is generated, the hydraulic motor 622 can be controlled to operate, thereby causing the barrier disc 616 and the rotating column 614 to rotate, and finally enabling the ore to leak down. A corrugated plate 68 is fixedly connected to the upper surface of the barrier disc 616. A limiting column 69 is fixedly connected to the lower surface of the screening frame 56.

A connecting rod 618 is fixedly connected to the lower surface of the sliding frame 610. The bottom end of the connecting rod 618 is fixedly connected to a pressing ball 619. The pressing ball 619 is in pressing fit with the upper surface of the corrugated plate 68. A moving plate 620 is fixedly connected to the upper surface of the sliding frame 610. A material-poking column 621 is fixedly connected to the upper surface of the moving plate 620. The material-poking column 621 is in frictional fit with the holes of the screening frame 56. By providing the limiting column 69, the sliding frame 610 can be limited, enabling the sliding frame 610 to move vertically up and down on the outer surface of the limiting column 69. By providing the third spring 611, after the sliding frame 610 moves upward, it can rebound. By providing the pressing ball 619, when the barrier disc 616 and the corrugated plate 68 rotate, the pressing ball 619 can drive the sliding frame 610 to move upward, thereby enabling the material-poking column 621 to poke out the ore stuck in the holes of the screening frame 56.

[0048] Working principle: When in use, the operator pours the ore to be crushed into the box body 1 through the opening of the top cover 3. Then, rotate the arc-shaped cover 43 to make the rotating frame 42 rotate on the outer surface of the limiting frame 41. After that, rotate the threaded rod 46 into the inner cavities of the first threaded ring 45 and the second threaded ring 47, so that the arc-shaped cover 43 tightly contacts the top cover 3 and the sealing ring 7. Then, the operator passes the load wire 498 through the positive diode 494 and the negative diode 495, and starts the high-voltage power supply to generate a high-voltage current and keep operating. When the load wire 498 is loaded, an explosion will occur, generating a shock wave. The shock wave generated by the explosion will be reflected to the reflection cone barrel 57 under the guidance of the arc-shaped cover 43, and then reflected by the reflection cone barrel 57 to the reflection ring 51. Then, under the action of the reflection ring 51, the shock wave contacts the ore, and the ore is cracked by the shock wave. Under the action of the shock wave, the gas in the inner cavity of the box body 1 expands rapidly, so that the first piston plate 62 moves horizontally in the inner cavity of the first limiting tube 61, and then the extrusion column 65 extrudes the second support rod 58, causing the second support rod 58 and the stirring plate 59 to move downward in the inner cavity of the box body 1, so that the ore in the inner cavity of the box body 1 and on the upper surface of the stirring plate 59 can be moved. Then, the ore crushed to a certain diameter size falls into the inner cavity of the discharge pipe 612 through the screening frame 56. While the first piston plate 62 moves, the gas inside is extruded, and the gas generated by the explosion is discharged through the opening of the first limiting tube 61. After the crushing is completed, the hydraulic motor 622 controls the rotating column 614 to rotate, and finally the blocking disc 616 and the gasket 617 rotate to the vertical state, so that the ore crushed to the specified diameter can be discharged.
