Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing, in particular to ore crushing equipment for tungsten ore analysis. Background Art

[0002] As an important strategic metal, tungsten is widely used in modern industry, including aerospace, national defense, electronics and electrical appliances. In order to ensure the effective utilization and development of tungsten ore resources, accurate analysis and testing is an indispensable part. When conducting tungsten ore analysis in the laboratory, it is usually necessary to collect large pieces of tungsten ore through a series of processing to obtain powdered samples suitable for analysis and testing. This process mainly includes coarse crushing, fine crushing, grinding and other steps.

[0003] In traditional tungsten ore pre-analysis processing, small jaw crushers are often used for the initial coarse crushing of large tungsten ore. However, relying solely on a jaw crusher is insufficient to directly produce a powder sample that meets analytical requirements. Further crushing and grinding operations are required using other pulverizing equipment, such as a ball mill or disc mill. During this process, the mechanical interaction between the equipment and the ore inevitably produces a certain amount of metal debris (such as iron powder). These impurities mix into the tungsten ore powder, seriously affecting its purity. This contamination can significantly reduce the accuracy of analytical results, especially for analyses of trace components.

[0004] In order to solve the above problems, the existing technology usually adopts the magnetic separation method to remove the iron powder mixed in the tungsten ore powder. Although this method can effectively remove some foreign iron powder, it also has a fatal disadvantage: it may remove the iron-containing mineral components originally present in the tungsten ore, resulting in distortion of the analysis data. This is because some types of tungsten ores may contain a certain proportion of iron elements, and the magnetic separation process does not distinguish between foreign contaminants and iron elements in the original minerals, which makes the subsequent tungsten ore analysis data inaccurate, affecting the correct assessment of the quality and value of the tungsten ore. Summary of the Invention

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

[0035] like Figure 6-Figure 9 As shown, the collecting assembly includes a collecting frame 22, a fixing sleeve 23, a water storage cylinder 24, a discharge valve 25, a limiting 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 water storage cylinder 24 is movably provided on the inner side of the fixing sleeve 23. The water storage cylinder 24 is made of transparent material, and the top of the water storage cylinder 24 is an open design. The water storage cylinder 24 is located directly above the collecting frame 22. A discharge valve 25 is installed at the lower end of the water storage cylinder 24. The upper part of the outer wall of the water storage cylinder 24 is connected to the limiting sleeve 26, and the bottom of the limiting sleeve 26 contacts the top of the fixing sleeve 23 for limiting the water storage cylinder 24. The rear side of the outer wall of the water storage cylinder 24 A water pump 27 is installed on the upper part, and a water pumping pipe 28 is connected between the water inlet of the water pump 27 and the upper rear part of the water storage cylinder 24 and maintained in communication.

The upper and lower sides of the inner wall of the vertical pipe 30 are connected with a fixed ring 32, the inner walls of the two fixed rings 32 are rotatably connected to the swivel 33, and the inner walls of the two swivels 33 are connected to the rubber ring 34.

[0036] When tungsten ore needs to be analyzed, 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, and then place the two ore samples 001 on the 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, and 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 to the side close to each other so that the two blocking rods 21 are in contact with the surface of the lower ore sample 001, and then move the two sliding frames 20 downward so that the two sliding frames 20 are respectively placed on the two fixed columns. 19, the fixed column 19 is used to limit the sliding frame 20; then the electric push rod 18 drives the sliding seat 17 to move a specified distance to the left along the guide rail 16, and the sliding seat 17 can drive the sliding plate 4 to move a specified distance to the left, and the sliding plate 4 can drive the lower side of the ore sample 001 to move a specified distance to the left through the lower side centering chuck 15, so that the two ore samples 001 are staggered, and then the electric slide 10 drives the upper side of the centering chuck 15 to move downward, which can drive the upper side of the ore sample 001 to move downward into between the two sliding frames 20, and make the surfaces of the two ore samples 001 contact each other, and then the second drive motor 11 drives the rotating shaft 13 to rotate, and 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 process, the flywheel 14 will reduce the speed fluctuation of the rotating shaft 13 by storing and releasing energy, so that the rotating shaft 13 rotates more smoothly. At the same time, the first drive motor 8 drives the lower centering chuck 15 and the lower ore sample 001 to rotate, 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 the two ore samples 001 may be taken out of the tungsten ore by the water drill, the surface of the ore sample 001 may remain with metal debris from the water drill, so the two ore samples 001 are controlled to rotate in opposite directions. Friction can remove impurities on the surface of the ore sample 001, and the impurities will fall into the sliding frame 20. Then, the first drive motor 8 and the second drive motor 11 are turned off, and the upper centering chuck 15 is driven by the electric slide rail 10 to move upward and reset, which can drive the upper ore sample 001 to move upward and reset. Then, the two sliding frames 20 are taken out, and the blocking rod 21 can prevent impurities in the sliding frame 20 from falling out. Then, the sliding seat 17 is driven by the electric push rod 18 to move right and reset. The sliding seat 17 can drive the sliding plate 4 to move right and reset. The sliding plate 4 can drive the lower ore sample 001 to move right 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 limiting sleeve 26 and the vertical pipe 30 to move upward, so that the limiting sleeve 26 is separated from the fixed sleeve 23, and then the water storage cylinder 24 is rotated ninety degrees, the water storage cylinder 24 can drive the vertical pipe 30 to rotate ninety degrees to between the two ore samples 001, and then push the water storage cylinder 24 downward to reset, the water storage cylinder 24 can drive the limiting sleeve 26 and the vertical pipe 30 to move downward to reset, so that the limiting sleeve 26 is in contact with the fixed sleeve 23 again, the limiting sleeve 26 is used to limit the water storage cylinder 24, and at the same time the vertical pipe 30 will be sleeved on the outside of the ore sample 001 on the lower side, and the inner wall of the rubber ring 34 on the lower side will contact and fit with the surface of the ore sample 001 on the lower side, and then an appropriate amount of water can be added to the water storage cylinder 24, and then driven by the electric slide rail 10 The upper ore sample 001 is moved downward at a uniform speed so that the lower end of the upper ore sample 001 can be inserted into the vertical tube 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 contact 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, and 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 tightly fitted, and then the first drive motor 8 and the second drive motor 11 are used to drive the two ore samples 001 to rotate respectively, so that the two ore samples 001 rub against each other to be crushed. At this time, the rotating ring 3 3 and the rubber ring 34 can rotate synchronously with the ore sample 001 to prevent the rubber ring 34 from being worn and ensure a good sealing effect. At the same time, the water pump 27 can be controlled to extract the water in the water storage cylinder 24 through the water pumping pipe 28, and the water is transported to the vertical pipe 30 through the outlet pipe 29, so that 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 reflux pipe 31. At this time, the ore powder in the water storage cylinder 24 will settle at the bottom thereof, and the upper clear water can be pumped away by the water pumping pipe 28 to form a water circulation cooling system; when the two ore samples 001 are basically crushed, the first drive motor 8, the second drive motor 11 and the water pump 27 are turned off, so that the ore powder continues to be crushed in the vertical pipe 30. After sedimentation occurs within the water storage cylinder 24, the remaining portion of the upper ore sample 001 is driven upward and reset by the electric slide 10, disengaging the remaining portions of the two ore samples 001. The connecting spring 7 returns to its original position, driving the first drive motor 8 and the lifting seat 6 upward and reset. The water storage cylinder 24 is then reversed and reset, disengaging the ore sample 001 from the rubber ring 34. The remaining portions of the two ore samples 001 are then removed from the centering chuck 15. The sliding door panel 3 is then slid downward and closed, and the discharge valve 25 is opened, allowing the precipitated ore powder within the water storage cylinder 24 to drain downward into the collection frame 22. The collection frame 22 is then manually removed, and the remaining water within the water storage cylinder 24 is then drained downward. Finally, the discharge valve 25 is closed.

[0037] like Figure 8 、 Figure 10 、 Figure 11 and Figure 12 As shown, it also includes a first iron ring 35, an annular 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 to the first iron ring 35, and the outer wall of the water storage cylinder 24 is slidably connected to the annular magnet 36, and the annular magnet 36 is adsorbed on the bottom of the first iron ring 35 by magnetic force. The inner wall of the water storage cylinder 24 is slidably connected to the second iron ring 37, and the annular magnet 36 adsorbs the second iron ring 37 by magnetic force. The lower part of the inner wall of the second iron ring 37 is connected to the connecting plate 38, and the connecting plate 38 is symmetrically opened. There is a through hole 3801, and the middle part of the connecting plate 38 is slidably connected to the lifting rod 39, and the upper end of the lifting rod 39 is connected to the baffle 40, and the baffle 40 blocks the top of the through hole 3801; when it is necessary to discharge the ore powder precipitated inside the water storage cylinder 24, the annular magnet 36 is first moved downward to separate the annular magnet 36 from the first iron ring 35, and the annular magnet 36 drives the second iron ring 37, the connecting plate 38, the lifting rod 39 and the baffle 40 to move downward through the magnetic force. At this time, the water under the connecting plate 38 will squeeze the lifting rod 39 and the baffle 40 As the connecting plate 38 moves upward, the baffle 40 no longer blocks the top of the through hole 3801, allowing the water below the connecting plate 38 to flow through the through hole 3801 to the top of the connecting plate 38. When the connecting plate 38 moves to the top of the ore powder, the annular magnet 36 stops moving downward, and the lifting rod 39 and the baffle 40 move downward relative to the connecting plate 38 under the action of gravity, causing the baffle 40 to block 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, and then the discharge valve is opened. 25, the ore powder in the water storage cylinder 24 can be discharged separately, thereby reducing the water content in the ore powder, facilitating subsequent analysis of the ore powder, and finally the annular magnet 36 is moved upward and reset. The annular magnet 36 can drive the second iron ring 37, the connecting plate 38, the lifting rod 39 and the baffle 40 to move upward and reset through magnetic force. The connecting plate 38 and the baffle 40 can squeeze the water in the water storage cylinder 24 upward. When the annular magnet 36 contacts the first iron ring 35, the annular magnet 36 will be re-adsorbed to the bottom of the first iron ring 35 through magnetic force.

[0038] like Figure 13 and Figure 14As shown, it also includes a square magnet 41, a connecting ring 42, a plastic sheet 43 and an arc-shaped iron sheet 44. The square magnets 41 are symmetrically connected to the front and back of the right side of the bottom of the shell 2. The two square magnets 41 are respectively located on the front and back sides of the water storage cylinder 24. The outer wall of the limiting sleeve 26 is connected to the connecting ring 42, and the outer wall of the connecting ring 42 is connected to the plastic sheet 43. The arc-shaped iron sheet 44 is connected to the plastic sheet 43, and the square magnet 41 on the rear side attracts the arc-shaped iron sheet 44 through magnetic force. When the user puts the water storage cylinder When 24 rotates ninety 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 ninety degrees, so that the arc-shaped iron sheet 44 is separated from the square magnet 41 on the rear side. When the arc-shaped iron sheet 44 contacts the square magnet 41 on the front side, the square magnet 41 on the front side can absorb the arc-shaped iron sheet 44 through 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] like Figure 8 As shown, a control valve 45 is also included, and a control valve 45 is installed at the lower end of the return pipe 31; the control valve 45 is initially open to allow the water and ore powder in the vertical pipe 30 to flow to the bottom of the water storage cylinder 24 through the return pipe 31. When it is necessary to discharge the ore powder precipitated in the water storage cylinder 24, the control valve 45 can be closed first to prevent the water remaining in the return pipe 31 from being discharged along with the ore powder, thereby ensuring that the discharged ore powder has a low water content, which is convenient for subsequent analysis of the ore powder.

[0040] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
