Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing, and particularly to an ore crushing device for tungsten ore analysis. Background Art

[0002] As an important strategic metal, tungsten has a wide range of applications in modern industries, including aerospace, national defense, electronics, and electrical appliances. To ensure the effective utilization and development of tungsten ore resources, accurate analysis and testing are an essential part. When analyzing tungsten ore in the laboratory, it is usually necessary to process the collected large pieces of tungsten ore through a series of steps to obtain a powdered sample suitable for analysis and detection. This process mainly includes coarse crushing, fine crushing, grinding, etc.

[0003] In the traditional pretreatment process before tungsten ore analysis, a small jaw crusher (jaw crusher) is often used for the initial coarse crushing of large pieces of tungsten ore. However, relying solely on the jaw crusher cannot directly obtain a powder sample that meets the analysis requirements, and other crushing equipment such as a ball mill or a disc mill needs to be further used for fine crushing and grinding operations. During this process, due to the mechanical action between the equipment and the ore, a certain amount of metal debris (such as iron powder) will inevitably be generated. These impurities mixed into the tungsten ore powder will seriously affect the purity of the ore powder. Especially for the analysis of trace components, this kind of pollution will significantly reduce the accuracy of the analysis results.

[0004] To solve the above problems, magnetic separation methods are usually used in the prior art to remove iron powder mixed in tungsten ore powder. Although this method can effectively remove some foreign iron powder, it also has a fatal drawback: that is, it may remove the iron-containing mineral components originally present in the tungsten ore, resulting in distorted analysis data. This is because some types of tungsten ore itself may contain a certain proportion of iron elements, and the magnetic separation process does not distinguish between foreign pollutants and iron elements in the primary minerals, thus making the subsequent tungsten ore analysis data inaccurate and affecting the correct evaluation of the quality and value of tungsten ore. Summary of the Invention

[0005] In view of this, the present invention provides an ore crushing device for tungsten ore analysis, which can overcome the drawback that when the existing crushing equipment processes tungsten ore, metal debris and other impurities will be mixed into the tungsten ore powder, thereby affecting the purity of the ore powder and reducing the accuracy of the analysis results.

The two sliding frames 20 are slidably matched with each other. Semi-circular holes are formed in the middle of the lower parts of the two sliding frames 20 to adapt to the shape of the ore sample 001. And blocking rods 21 are connected to the inner bottoms of the two sliding frames 20. The middle parts of the two blocking rods 21 are semi-circular in shape to adapt to the shape of the ore sample 001. And sealing rings are provided on the sides of the middle parts of the two blocking rods 21 close to each other to fit the surface of the ore sample 001.

[0035] As Figures 6-9 shown in the figure, the collection component includes a collection frame 22, a fixed sleeve 23, a water storage cylinder 24, a discharge valve 25, a limit sleeve 26, a water pump 27, a water suction pipe 28, a water outlet pipe 29, a vertical pipe 30, a return pipe 31 and a sealing mechanism. A collection frame 22 is placed on the right side of the lower part of the support frame 1. A fixed sleeve 23 is connected to the right side of the lower part of the outer shell 2. A water storage cylinder 24 is movably arranged inside the fixed sleeve 23. The water storage cylinder 24 is made of transparent material. The top of the water storage cylinder 24 is of an open design. And the water storage cylinder 24 is located directly above the collection frame 22. A discharge valve 25 is installed at the lower end of the water storage cylinder 24. A limit sleeve 26 is connected to the upper part of the outer wall of the water storage cylinder 24. And the bottom of the limit sleeve 26 is in contact with the top of the fixed sleeve 23 to limit the water storage cylinder 24. A water pump 27 is installed on the upper part of the rear side of the outer wall of the water storage cylinder 24. A water suction pipe 28 is connected between the water inlet of the water pump 27 and the upper part of the rear side of the water storage cylinder 24 and kept in communication. A water outlet pipe 29 is connected to the water outlet of the water pump 27 and kept in communication. The front end of the water outlet pipe 29 is connected to a vertical pipe 30 and kept in communication. A return pipe 31 is connected to the water storage cylinder 24 and kept in communication. And the upper end of the return pipe 31 is connected to the lower part of the rear side of the vertical pipe 30 and kept in communication. A sealing mechanism for sealing the inside of the vertical pipe 30 is provided inside the vertical pipe 30. The sealing mechanism includes a fixed ring 32, a rotating ring 33 and a rubber ring 34. Fixed rings 32 are connected to the upper and lower sides of the inner wall of the vertical pipe 30. Rotating rings 33 are rotatably connected to the inner walls of the two fixed rings 32. Rubber rings 34 are connected to the inner walls of the two rotating rings 33.

[0036] When it is necessary to analyze tungsten ore, first use a water drill to take out two ore samples 001 from the tungsten ore. Then slide the sliding door panel 3 upward to open it. Next, place the two ore samples 001 on two centering chucks 15 respectively, and clamp the ends of the ore samples 001 through the centering chucks 15. At this time, the two ore samples 001 are in a vertically aligned state. Then place the two sliding frames 20 on the front and back sides of the lower ore sample 001 respectively, and move the two sliding frames 20 towards each other and close them so that both stop bars 21 are in contact with the surface of the lower ore sample 001. Then move the two sliding frames 20 downward so that the two sliding frames 20 are respectively sleeved on the two fixed columns 19. The fixed columns 19 are used to limit the sliding frames 20. Then drive the sliding seat 17 to move leftward a specified distance along the guide rail 16 through the electric push rod 18. The sliding seat 17 can drive the sliding plate 4 to move leftward a specified distance. The sliding plate 4 can drive the lower ore sample 001 to move leftward a specified distance through the lower centering chuck 15, so that the two ore samples 001 are staggered. Then drive the upper centering chuck 15 to move downward through the electric slide rail 10, which can drive the upper ore sample 001 to move downward and enter between the two sliding frames 20, and make the surfaces of the two ore samples 001 contact each other. Then drive the rotating shaft 13 to rotate through the second driving motor 11. The rotating shaft 13 can drive the flywheel 14, the upper centering chuck 15 and the upper ore sample 001 to rotate. During the rotation of the flywheel 14, it will reduce the rotational speed fluctuation of the rotating shaft 13 by storing and releasing energy, making the rotation of the rotating shaft 13 more stable. At the same time, drive the lower centering chuck 15 and the lower ore sample 001 to rotate through the first driving motor 8, so that the two ore samples 001 rotate in opposite directions, which can make the surfaces of the two ore samples 001 rub against each other. Since there may be metal debris on the water drill remaining on the surface of the ore sample 001 during the process of taking out the two ore samples 001 from the tungsten ore with a water drill, by controlling the two ore samples 001 to rotate in reverse and rub, the impurities on the surface of the ore sample 001 can be removed, and the impurities will fall into the sliding frame 20. Then turn off the first driving motor 8 and the second driving motor 11, and drive the upper centering chuck 15 to move upward and reset through the electric slide rail 10, which can drive the upper ore sample 001 to move upward and reset. Then take out the two sliding frames 20. The stop bars 21 can prevent the impurities in the sliding frames 20 from falling out. Then drive the sliding seat 17 to move rightward and reset through the electric push rod 18. The sliding seat 17 can drive the sliding plate 4 to move rightward and reset. The sliding plate 4 can drive the lower ore sample 001 to move rightward and reset through the lower centering chuck 15, so that the two ore samples 001 are vertically aligned;Then pull the water storage cylinder 24 upward. The water storage cylinder 24 can drive the limit sleeve 26 and the vertical pipe 30 to move upward, so that the limit sleeve 26 is separated from the fixed sleeve 23. Then rotate the water storage cylinder 24 by ninety degrees. The water storage cylinder 24 can drive the vertical pipe 30 to rotate by ninety degrees to between the two ore samples 001. Then push the water storage cylinder 24 downward to reset. The water storage cylinder 24 can drive the limit sleeve 26 and the vertical pipe 30 to move downward and reset, so that the limit sleeve 26 comes into contact with the fixed sleeve 23 again. The limit sleeve 26 is used to limit the water storage cylinder 24. At the same time, the vertical pipe 30 will be sleeved outside the lower ore sample 001, and the inner wall of the lower rubber ring 34 will contact and fit with the surface of the lower ore sample 001. Then an appropriate amount of water can be added into the water storage cylinder 24. Then drive the upper ore sample 001 to move downward at a constant speed through the electric slide rail 10, so that the lower end of the upper ore sample 001 can be inserted into the vertical pipe 30, and the inner wall of the upper rubber ring 34 will contact and fit with the surface of the upper ore sample 001. When the ends of the two ore samples 001 are in contact with each other, the upper ore sample 001 will squeeze the lower ore sample 001 to move downward, and the lower ore sample 001 will squeeze the first drive motor 8 and the lifting seat 6 to move downward. The connecting spring 7 is compressed. Under the elastic force of the connecting spring 7, the ends of the two ore samples 001 can be closely fitted. Then drive the two ore samples 001 to rotate respectively through the first drive motor 8 and the second drive motor 11, so that the two ore samples 001 rub against each other to be crushed. At this time, the rotating ring 33 and the rubber ring 34 can rotate synchronously with the ore sample 001, preventing the rubber ring 34 from being worn and ensuring a good sealing effect. At the same time, the water pump 27 can be controlled to draw the water in the water storage cylinder 24 through the water suction pipe 28 and transport the water to the vertical pipe 30 through the water outlet pipe 29. In this way, the ends of the two ore samples 001 can be cooled, and the crushed ore powder can be mixed into the water and flow to the bottom of the water storage cylinder 24 through the return pipe 31. At this time, the ore powder in the water storage cylinder 24 will precipitate at its bottom, and the upper clear water can be drawn away by the water suction pipe 28, forming a water circulation cooling system; when the two ore samples 001 are basically crushed, turn off the first drive motor 8, the second drive motor 11 and the water pump 27, so that the ore powder continues to precipitate in the water storage cylinder 24. Then the remaining part of the upper ore sample 001 can be driven to move upward and reset through the electric slide rail 10, so that the remaining parts of the two ore samples 001 are separated. The connecting spring 7 will return to its original state, driving the first drive motor 8 and the lifting seat 6 to move upward and reset. Then reverse the water storage cylinder 24 to reset, so that the ore sample 001 is separated from the rubber ring 34. Then take out the remaining parts of the two ore samples 001 from the centering chuck 15. Then slide the sliding door panel 3 downward to close it. Then open the discharge valve 25, so that the ore powder precipitated inside the water storage cylinder 24 can be discharged downward into the collection frame 22. Then the collection frame 22 is taken away by the operator. Subsequently, the remaining water inside the water storage cylinder 24 can also be discharged downward. Finally, close the discharge valve 25.;

[0037] As shown Figure 8 , Figure 10 , Figure 11 and Figure 12 in the figure, it further includes a first iron ring 35, a ring magnet 36, a second iron ring 37, a connecting plate 38, a lifting rod 39 and a baffle 40. The upper part of the outer wall of the water storage cylinder 24 is connected with the first iron ring 35. The outer wall of the water storage cylinder 24 is slidably connected with the ring magnet 36, and the ring magnet 36 is magnetically adsorbed at the bottom of the first iron ring 35. The inner wall of the water storage cylinder 24 is slidably connected with the second iron ring 37, and the ring magnet 36 magnetically adsorbs the second iron ring 37. The lower part of the inner wall of the second iron ring 37 is connected with the connecting plate 38, and through holes 3801 are symmetrically formed in the connecting plate 38. The middle part of the connecting plate 38 is slidably connected with the lifting rod 39. The upper end of the lifting rod 39 is connected with the baffle 40, and the baffle 40 blocks the upper part of the through hole 3801. When it is necessary to discharge the ore powder precipitated inside the water storage cylinder 24, first move the ring magnet 36 downward to separate the ring magnet 36 from the first iron ring 35. The ring magnet 36 can drive the second iron ring 37, the connecting plate 38, the lifting rod 39 and the baffle 40 to move downward by magnetic force. At this time, the water below the connecting plate 38 will squeeze the lifting rod 39 and the baffle 40 to move upward relative to the connecting plate 38, and the baffle 40 no longer blocks the upper part of the through hole 3801, so that the water below the connecting plate 38 can flow through the through hole 3801 to the upper part of the connecting plate 38. When the connecting plate 38 moves to the top of the ore powder, stop moving the ring magnet 36 downward. The lifting rod 39 and the baffle 40 will move downward relative to the connecting plate 38 under the action of gravity, so that the baffle 40 blocks the through hole 3801 again. At this time, the ore powder and water in the water storage cylinder 24 can be separated by the connecting plate 38 and the baffle 40. Then open the discharge valve 25, and the ore powder in the water storage cylinder 24 can be discharged alone, so as to reduce the water content in the ore powder and facilitate the subsequent analysis of the ore powder. Finally, move the ring magnet 36 upward to reset. The ring magnet 36 can drive the second iron ring 37, the connecting plate 38, the lifting rod 39 and the baffle 40 to move upward to reset. The connecting plate 38 and the baffle 40 can squeeze the water in the water storage cylinder 24 upward. When the ring magnet 36 contacts the first iron ring 35, the ring magnet 36 will be magnetically adsorbed at the bottom of the first iron ring 35 again.

[0038] As shown Figure 13 and Figure 14As shown in the figure, it further includes a square magnet 41, a connecting ring 42, a plastic sheet 43 and an arc-shaped iron sheet 44. On the right side of the inner bottom of the outer shell 2, square magnets 41 are symmetrically connected in the front and back. The two square magnets 41 are respectively located on the front and back sides of the water storage cylinder 24. A connecting ring 42 is connected to the outer wall of the limiting sleeve 26. A plastic sheet 43 is connected to the outer wall of the connecting ring 42. An arc-shaped iron sheet 44 is connected to the plastic sheet 43. And the square magnet 41 at the rear adsorbs the arc-shaped iron sheet 44 by magnetic force. When the user rotates the water storage cylinder 24 by 90 degrees, the water storage cylinder 24 can drive the limiting sleeve 26, the vertical pipe 30, the connecting ring 42, the plastic sheet 43 and the arc-shaped iron sheet 44 to rotate by 90 degrees, so that the arc-shaped iron sheet 44 is separated from the square magnet 41 at the rear. When the arc-shaped iron sheet 44 contacts the square magnet 41 at the front, the square magnet 41 at the front can adsorb the arc-shaped iron sheet 44 by magnetic force to position the water storage cylinder 24 and the vertical pipe 30, ensuring that the vertical pipe 30 can be accurately rotated between the two ore samples 001.

[0039] As Figure 8 As shown in the figure, it further includes a control valve 45. A control valve 45 is installed at the lower end of the return pipe 31. The control valve 45 is in an open state initially, so that the water and ore powder in the vertical pipe 30 can flow through the return pipe 31 to the inner bottom of the water storage cylinder 24. When it is necessary to discharge the ore powder precipitated in the water storage cylinder 24, the control valve 45 can be closed first, so that the water remaining in the return pipe 31 will not be discharged together with the ore powder, ensuring that the discharged ore powder has a low water content and is convenient for subsequent analysis of the ore powder.

[0040] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
