Description

Technical Field

[0001] This invention relates to the field of ore crushing technology, specifically to an ore crushing device based on the electric explosion of metal wires. Background Technology

[0002] Shockwave crushing technology is a highly efficient physical method that uses high-energy shockwaves to break up ores. Its core principle is to create stress concentration within the ore through the instantaneous release of shockwave energy, causing the expansion of mineral grain boundaries or internal cracks, thereby achieving selective crushing. This technology can be divided into two categories: mechanical shockwaves (such as high-pressure gas-driven pistons) and electromagnetic pulse shockwaves (which generate plasma expansion through capacitor discharge). It has advantages such as low energy consumption, low dust, and low crushing rate, and is particularly suitable for the pre-selection and disposal of high-hardness minerals or ores containing rare metals.

[0003] In the ore crushing process, complete crushing is not always necessary. Instead, the ore needs to be crushed to a specific particle size range according to the requirements of subsequent mineral processing. Over-crushing not only wastes energy but also has a series of adverse effects on the mineral processing flow. Excessive crushing can lead to excessive mixing of useful minerals and gangue minerals, increasing the difficulty of mineral liberation and reducing separation efficiency. In processes such as gravity separation and magnetic separation, excessively fine mineral particles are easily lost with the tailings, resulting in a decrease in metal recovery rate. In addition, over-crushing can significantly increase the energy and steel consumption of the grinding process and increase production costs. Summary of the Invention

[0019] This invention provides a ore crushing device based on the electric explosion of metal wire. It has the following beneficial effects:

[0020] I. The ore crushing device based on metal wire electric explosion can open the box by setting a shock wave device, so as to facilitate the placement of the ore to be crushed into the inner cavity of the box. After the opening of the box is closed, a shock wave can be generated into the inner cavity of the box, thereby completing the crushing of the ore in the inner cavity of the box.

[0021] II. The ore crushing device based on metal wire electric explosion, by setting up a stirring mechanism, can use the force generated by the explosion to stir the ore in the inner cavity of the box when the shock wave device emits a shock wave into the inner cavity of the box and causes an explosion in the inner cavity of the box. During the stirring process, the ore that has been crushed to a certain degree is discharged.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0037] like Figures 1-10 As shown, the present invention provides a technical solution: a crushing device based on metal wire electric explosion, comprising a housing 1 and a frame 2 fixedly connected to the outer surface of the housing 1;

[0038] Shockwave device 4 is used to crush the ore in the inner cavity of the box 1. The top cover 3 is set on the lower surface of the shockwave device 4. By setting the shockwave device 4, the opening of the box 1 can be opened, so that the ore to be crushed can be placed in the inner cavity of the box 1. Then the opening of the box 1 is closed, and then a shock wave can be generated into the inner cavity of the box 1, thereby completing the crushing work of the ore in the inner cavity of the box 1.

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

[0040] Automatic discharge mechanism 6 is used to automatically discharge the crushed ore in the inner cavity of the box 1. By setting the automatic discharge mechanism 6, the stirring mechanism 5 can be stirred in the inner cavity of the box 1 at the same time as the explosion occurs in the inner cavity of the box 1. At the same time, the ore crushed to a certain diameter can be discharged. Afterwards, the inner cavity of the box 1 is restored to a closed state to prevent the shock wave generated by the shock wave device 4 from leaking out and affecting the crushing effect.

[0041] The top cover 3 is fixedly connected to the upper surface of the box 1, the shock wave device 4 is fixedly connected to the upper surface of the box 1 through the top cover 3, the stirring mechanism 5 is set in the inner cavity of the box 1, and the automatic discharge mechanism 6 is set on the outer surface of the box 1.

[0042] The automatic discharge mechanism 6 includes a discharge pipe 612, with a baffle plate 616 rotatably connected to the inner cavity of the discharge pipe 612. A washer 617 is fixedly connected to the outer ring of the baffle plate 616. The washer 617 is squeezed and adapted to the inner wall of the discharge pipe 612. By setting the baffle plate 616 and the washer 617, the inner cavity of the discharge pipe 612 can be sealed to prevent ore leakage. At the same time, the ore can be discharged when the baffle plate 616 and the washer 617 are in a vertical position.

[0043] The shock wave device 4 includes a limiting frame 41, which is fixedly connected to the upper surface of the top cover 3. A rotating frame 42 is rotatably connected to the outer surface of the limiting frame 41. An arc-shaped cover 43 is fixedly connected to the end of the rotating frame 42. The arc-shaped cover 43 is made of metal and has a parabolic cross-section. A sealing ring 7 is fixedly connected to the upper surface of the top cover 3. The sealing ring 7 is press-fitted to the outer surface of the arc-shaped cover 43. By setting the arc-shaped cover 43, the shock wave generated by the metal wire explosion can be guided, allowing the shock wave to be transmitted to the surface of the ore. By setting the sealing ring 7, it can cooperate with the arc-shaped cover 43, ensuring no gap between the arc-shaped cover 43 and the top cover 3, thereby preventing air from escaping. By setting the limiting frame 41, it is possible to... The rotating frame 42 is limited to allow it to drive the arc-shaped cover 43 to rotate. A first support rod 44 is fixedly connected to the outer surface of the arc-shaped cover 43. A first threaded ring 45 is fixedly connected to the end of the first support rod 44. A threaded rod 46 is threadedly connected to the inner cavity of the first threaded ring 45. A second threaded ring 47 is threadedly connected to the bottom end of the threaded rod 46. The second threaded ring 47 is fixedly connected to the upper surface of the top cover 3. By setting the first threaded ring 45, the second threaded ring 47, and the threaded rod 46, after the arc-shaped cover 43 seals the opening of the top cover 3, the threaded rod 46 can be rotated into the inner cavity of the first threaded ring 45 and the second threaded ring 47, thereby preventing the arc-shaped cover 43 from loosening when a shock wave occurs.

[0044] A fixing frame 48 is fixedly connected to the upper surface of the arc-shaped cover 43. A shock wave generating mechanism 49 is provided in the inner cavity of the arc-shaped cover 43. The shock wave generating mechanism 49 includes a connecting frame 492, which is fixedly connected to the inner wall of the arc-shaped cover 43. By setting the shock wave generating mechanism 49, the metal wire can be made to explode during operation, thereby generating an explosion in the inner cavity of the housing 1, and the shock wave can crush the ore. An insulating tube 493 is fixedly connected to the inner wall of the connecting frame 492. There are two insulating tubes 493, and the two insulating tubes 493 are symmetrically fixedly connected to the inner wall of the connecting frame 492. A positive electrode tube 494 and a negative electrode tube 495 are respectively fixedly connected to the inner cavity of the two insulating tubes 493. The inner cavities of the positive electrode tube 494 and the negative electrode tube 495 are slidably connected. The device has a load wire 498. The end of the positive electrode 494 is connected to a first wire 496, and the end of the negative electrode 495 is connected to a second wire 497. The first wire 496 and the second wire 497 are respectively fixedly connected to the positive and negative terminals of an external high-voltage power supply. When the high-voltage power supply is working, the high-voltage current passes through the first wire 496 and the second wire 497 to form a closed circuit. By setting an insulating tube 493, the leakage of current through the positive electrode 494 and the negative electrode 495 is prevented from causing a short circuit. By setting the first wire 496 and the second wire 497, the positive electrode 494 and the negative electrode 495 can be connected to the positive and negative terminals of the high-voltage power supply respectively. When the high-voltage power supply is working, the load wire 498 is connected to the circuit. Under the action of continuous high-voltage current, the load wire 498 explodes, thereby generating a shock wave.

[0045] The mixing mechanism 5 includes a reflective ring 51 and a screening frame 56. The reflective ring 51 is made of metal and is slidably connected to the inner cavity of the housing 1. A fixing block 52 is fixedly connected to the upper surface of the reflective ring 51, and 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 screening frame 56 is fixedly connected to the inner wall of the housing 1, and a reflective cone 5 is fixedly connected to the upper surface of the screening frame 56. 7. The reflective cone 57 is made of metal. By setting a reflective ring 51 and a reflective cone 57, it 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 reflective cone 57, and then reflected to the inner ring of the reflective ring 51, and then reflected by the reflective ring 51 onto the ore on the upper surface of the screen frame 56, so that the shock wave is evenly reflected onto the ore. By setting a first spring 53, the reflective ring 51 can be supported. The box body A track groove 8 is provided on the inner wall of the housing 1. A limiting frame 54 is fixedly connected to the outer surface of the reflective ring 51. A ball bearing 55 is slidably connected to the inner cavity of the limiting frame 54. The ball bearing 55 is slidably connected to the track groove 8. A second support rod 58 is fixedly connected to the lower surface of the reflective ring 51. A slot is provided on the outer surface of the second support rod 58. A stirring plate 59 is fixedly connected to the bottom end of the second support rod 58. By setting the track groove 8, it can cooperate with the ball bearing 55, so that when the reflective ring 51 is subjected to extrusion force and moves up and down, the reflective ring 51 will only move vertically up and down in the inner cavity of the housing 1 and will not rotate. By setting the limiting frame 54, the ball bearing 55 can be limited, so that the ball bearing 55 can generate stable rotation in the inner cavity of the limiting frame 54, so that the reflective ring 51 will not be subjected to too much friction when moving up and down. By setting the second support rod 58 and the stirring plate 59, the ore in the inner cavity of the screen frame 56 can be stirred when the reflective ring 51 moves up and down.

[0046] The automatic feeding mechanism 6 includes a first limiting tube 61, which penetrates the outer surface of the housing 1. A first piston plate 62 is slidably connected to the inner cavity of the first limiting tube 61. A sealing ring 63 is fixedly connected to the outer surface of the first piston plate 62. A third support rod 64 is fixedly connected to the outer surface of the first piston plate 62. A pressing column 65 is fixedly connected to one end of the third support rod 64, which passes through the second support rod 58. The pressing column 65 is adapted to the surface of the second support rod 58. 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 6 is fixedly connected to the inner wall of the first limiting tube 61. By setting the first limiting tube 61, the first piston plate 62 can be limited, so that the first piston plate 62 can move laterally in the inner cavity of the first limiting tube 61. When the shock wave is generated and the gas in the inner cavity of the box 1 expands, the first piston plate 62 is subjected to pressure and moves, thereby driving the third support rod 64 and the extrusion column 65 to move laterally, thereby causing the extrusion column 65 to extrude pressure on the second support rod 58, and finally causing the stirring plate 59 to move downward. By setting the second spring 66, the first piston plate 62 can bounce back to its original position after moving.

[0047] A third limiting tube 613 penetrates the outer side of the discharge pipe 612. A rotating column 614 is rotatably connected to the inner cavity of the third limiting tube 613. A connecting frame 615 is fixedly connected to the end of the rotating column 614. The connecting frame 615 is fixedly connected to the outer surface of the barrier plate 616. A positioning plate 67 is fixedly connected to the outer surface of the discharge pipe 612. A hydraulic motor 622 is fixedly connected to the upper surface of the positioning plate 67. The output end of the hydraulic motor 622 is fixedly connected to the end of the rotating column 614. By setting the third limiting tube... Pipe 613 can limit the rotation of column 614, allowing column 614 to rotate stably within the inner cavity of the third limiting pipe 613. A hydraulic motor 622 is installed, which can be activated after the shock wave is generated, causing the baffle plate 616 and the rotation of column 614 to rotate, ultimately allowing the ore to pass through. A corrugated plate 68 is fixedly connected to the upper surface of the baffle plate 616, and a limiting post 69 is fixedly connected to the lower surface of the screen frame 56. A sliding frame 610 is slidably connected to the outer surface of the limiting post 69. A third spring 611 is sleeved on the outer surface of the limiting post 69. The top end of the third spring 611 is fixedly connected to the top surface of the inner cavity of the sliding frame 610. A connecting rod 618 is fixedly connected to the lower surface of the sliding frame 610. A compression ball 619 is fixedly connected to the bottom end of the connecting rod 618. The compression ball 619 is adapted to 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-push column 621 is fixedly connected to the upper surface of the moving plate 620. The material-push column 621 is connected to the screen frame 56. The hole friction is adapted, and by setting the limiting post 69, the sliding frame 610 can be limited, so that the sliding frame 610 can move vertically up and down on the outer surface of the limiting post 69. By setting the third spring 611, the sliding frame 610 can rebound after moving upward. By setting the extrusion ball 619, when the blocking plate 616 and the wave plate 68 rotate, the extrusion ball 619 can drive the sliding frame 610 to move upward, thereby causing the material-pushing post 621 to push out the ore stuck in the hole of the screen frame 56.

[0048] Working principle: During use, the operator pours the ore to be crushed into the housing 1 through the opening of the top cover 3. Then, the operator rotates the arc-shaped cover 43, causing the rotating frame 42 to rotate on the outer surface of the limiting frame 41. The threaded rod 46 is then rotated into the inner cavity of the first threaded ring 45 and the second threaded ring 47, thus ensuring that the arc-shaped cover 43 is in tight contact with the top cover 3 and the sealing ring 7. The operator then passes the load wire 498 through the positive electrode tube 494 and the negative electrode tube 495, and starts the high-voltage power supply, generating a high-voltage current that continues to operate. When the load wire 498 is loaded, an explosion occurs, generating a shock wave. Guided by the arc-shaped cover 43, the shock wave is reflected to the reflective cone 57, and then reflected by the reflective cone 57 to the reflective ring 51. Under the action of the reflective ring 51, the shock wave contacts the ore, causing it to crack. Under the action of the shock wave, the gas in the inner cavity of the housing 1 expands rapidly, causing the first piston plate 62 to... The first piston plate 61 moves laterally within the inner cavity of the limiting tube 61, thereby causing the extrusion column 65 to extrude force against the second support rod 58. This causes the second support rod 58 and the agitator plate 59 to move downward within the inner cavity of the housing 1, allowing the ore within the housing 1 and on the upper surface of the agitator plate 59 to be moved. This allows the ore, crushed to a certain diameter, to fall through the screen frame 56 into the inner cavity of the discharge pipe 612. Simultaneously, the first piston plate 62 moves, compressing the internal gas. The gas generated by the explosion passes through the first limiting tube 61. After crushing is completed, the hydraulic motor 622 controls the rotating column 614 to rotate, which eventually causes the baffle plate 616 and the washer 617 to rotate to a vertical position, so that the ore crushed to the specified diameter can be discharged. When the baffle plate 616 rotates, it will drive the wave plate 68 to rotate, which will cause the extrusion ball 619 to drive the sliding frame 610 to move upward, so that the shovel column 621 can push out the ore stuck in the hole of the screen frame 56 to prevent ore blockage.
