Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of ball mills, and more specifically, to a small double-power ball mill for gold ore pulverization. Background Art

[0002] A ball mill is an existing technical device for pulverizing and grinding relatively small materials after preliminary crushing or materials with small volumes themselves. A ball mill generally consists of a rotating cylinder, a mounting support, and a transmission device. By adding the materials to be ground and steel balls together into the rotating cylinder, and starting the transmission device to drive the rotating cylinder to rotate on the mounting support, finally, the steel balls and the materials rotate together with the rotating cylinder to make full contact. After the rotating cylinder rotates for a certain period of time, the steel balls perform a full pulverization operation on the materials.

[0003] There are many types of ball mills in the prior art, which are mostly used for pulverizing various ores. However, in real life, the production areas of many ores are generally located in relatively primitive or inaccessible areas. For example, gold ores are generally distributed in some desert mountainous areas at home and abroad. In order to save the transportation cost of ores, the ball mills used for ore treatment are generally installed at the ore mining sites. The driving energy of the ball mills in the prior art can generally be divided into electric energy or the combustion energy after diesel combustion. When the ball mill is installed and used in the ore mining area, only a single energy source is used to drive the ball mill. Due to environmental factors, the supply of electric energy or diesel is problematic, affecting the normal use of the ball mill. Summary of the Invention

[0026] As Figures 1 to 8 shown, the present invention discloses a small double-power ball mill for gold ore grinding, which includes a mounting support 1. Rotating brackets 2 are provided on both sides of the top of the mounting support 1, and a mounting bracket 3 is provided in the middle of the mounting support 1. A rotating cylinder one 4 is rotatably arranged between one of the rotating brackets 2 and the mounting bracket 3, and a rotating cylinder two 5 is rotatably arranged between the other rotating bracket 2 and the mounting bracket 3. By adding gold ore materials and steel balls into the rotating cylinder one 4 and the rotating cylinder two 5, the rotating cylinder one 4 and the rotating cylinder two 5 are rotated, so that the gold ore materials and the steel balls are in full contact in the rotating cylinder one 4 and the rotating cylinder two 5, and the grinding operation of the gold ore is completed.

[0027] It further includes a middle transmission mechanism 100. A middle transmission mechanism 100 is provided between the mounting support 1 and the mounting bracket 3. The middle transmission mechanism 100 uses electric energy as the driving energy. The rotating cylinder one 4 is engaged with the middle transmission mechanism 100.

A rotating ring sleeve 7 is rotatably connected in the mounting ring sleeve 6. A rotating shaft 8 is fixedly connected to the side of the rotating cylinder one 4 close to the rotating ring sleeve 7. The rotating shaft 8 is engaged with the rotating ring sleeve 7. In the actual use process of the present invention, the rotating cylinder one 4 is kept connected after being engaged with the rotating ring sleeve 7 through the rotating shaft 8, so that the rotating ring sleeve 7 drives the rotating shaft 8 and the rotating cylinder one 4 to rotate during rotation; The motor driving device 9 is arranged on the mounting support 1. A first clutch 10 is arranged on the mounting support 1. The output end of the motor driving device 9 is connected to the first clutch 10. An output shaft 11 is arranged on the first clutch 10. A belt transmission structure is arranged between the output shaft 11 and the rotating ring sleeve 7. The belt transmission structure includes belt pulleys 34. Belt pulleys 34 are arranged on both the rotating ring sleeve 7 and the output shaft 11 of the first clutch 10. A plurality of transmission belts 35 are arranged for transmission between the two belt pulleys 34. When it is necessary to drive the rotating ring sleeve 7 to rotate, by operating the first clutch 10, the output end of the motor driving device 9 is kept in transmission connection with the output shaft 11 on the first clutch 10. The motor driving device 9 is started to drive the output shaft 11 of the first clutch 10 to rotate. The rotating ring sleeve 7 is rotated through the belt pulleys 34 and the transmission belts 35. During the rotation of the rotating ring sleeve 7, the components meshing with it will be driven to rotate together.

[0028] A separable connection mechanism 200 is arranged between the rotating cylinder body two 5 and the middle transmission mechanism 100. The separable connection mechanism 200 includes a fixed sleeve 12 and a moving component. A fixed sleeve 12 is fixedly connected to the side of the rotating cylinder body two 5 close to the rotating ring sleeve 7. An insertion shaft 13 is slidably connected in the fixed sleeve 12. The insertion shaft 13 meshes with the rotating ring sleeve 7. A moving component is arranged between the mounting ring sleeve 6 and the insertion shaft 13. When it is necessary to drive the rotating cylinder body two 5 to rotate by the rotating ring sleeve 7, the insertion shaft 13 is inserted into the insertion chamber 16 of the rotating ring sleeve 7 through the moving component, so that the insertion shaft 13 and the rotating ring sleeve 7 are kept in a meshing relationship. During the rotation of the rotating ring sleeve 7, the rotating ring sleeve 7 drives the insertion shaft 13 and the rotating cylinder body two 5 to rotate, completing the driving operation of the rotating ring sleeve 7 on the rotating cylinder body two 5. An internal tooth section 14 is arranged on the side of the rotating ring sleeve 7 close to the rotating shaft 8. A spline section 15 is arranged on the rotating shaft 8. The spline section 15 meshes with the internal tooth section 14. An insertion chamber 16 is arranged on the side of the rotating ring sleeve 7 close to the insertion shaft 13. The insertion chamber 16 meshes with the insertion shaft 13. The rotating shaft 8 and the rotating ring sleeve 7 are meshed through the spline section 15 and the internal tooth section 14. After the insertion shaft 13 enters the insertion chamber 16, the insertion shaft 13 and the rotating ring sleeve 7 are kept in meshing. The moving component includes an annular sliding seat 17, a mounting plate body 19, a pushing plate body 20 and a meshing transmission structure. The annular sliding seat 17 is fixedly sleeved on the insertion shaft 13. A sliding block 18 is slidably connected to the annular sliding seat 17. The mounting plate body 19 is fixedly connected to the mounting ring sleeve 6. The pushing plate body 20 is fixedly connected to the sliding block 18. A sliding piece 21 is fixedly connected to the middle of the pushing plate body 20. The sliding piece 21 is slidably connected to the bottom of the mounting plate body 19. A meshing transmission structure is arranged between the mounting plate body 19 and the pushing plate body 20. Because during the process of the rotating ring sleeve 7 driving the insertion shaft 13 to rotate, the insertion shaft 13 and the rotating cylinder body II 5 will rotate together, and the sliding block 18 will slide within the annular sliding seat 17, so that the pushing plate body 20 remains stationary at the top of the insertion shaft 13. And during the process of the pushing plate body 20 pushing the sliding block 18 to move, the annular sliding seat 17 and the insertion shaft 13 move horizontally together, and the insertion shaft 13 will move within the fixed sleeve 12, so that the insertion shaft 13 moves towards the inside of the fixed sleeve 12 or moves outwards from the inside and outside of the fixed sleeve 12; The meshing transmission structure includes an internal tooth groove 22 and a driving motor 24. The internal tooth groove 22 is arranged on the pushing plate body 20. A transmission gear 23 is meshed with the internal tooth groove 22. The driving motor 24 is arranged on the mounting plate body 19. The transmission gear 23 is arranged on the output end of the driving motor 24. When it is necessary to make the pushing plate body 20 drive the annular sliding seat 17 and the insertion shaft 13 to move, the driving motor 24 is started to drive the transmission gear 23 to rotate along the output end of the driving motor 24. Through the meshing relationship between the transmission gear 23 and the transmission tooth plate, the pushing plate body 20 slides at the bottom of the mounting plate body 19. A sliding groove body is opened on one side of the bottom of the mounting plate body 19. The top of the sliding piece 21 slides within the sliding groove body, which can not only make the pushing plate body 20 remain stationary at the top of the insertion shaft 13, but also keep the horizontal movement of the pushing plate body 20 stable.

[0029] A rotation positioning assembly 300 is provided between the first rotating cylinder 4 and the second rotating cylinder 5 and the two rotating brackets 2 respectively. The rotation positioning assembly 300 includes a mounting base 25, a mounting shaft 26 and an electromagnet 28. A mounting base 25 is fixedly connected to the top of the rotating bracket 2. Mounting shafts 26 are fixedly connected to both the first rotating cylinder 4 and the second rotating cylinder 5. An annular protrusion 27 is provided on the mounting shaft 26. The annular protrusion 27 is rotatably arranged in the mounting base 25. An electromagnet 28 is provided on the top of the mounting base 25. A plurality of ferromagnetic sheets 29 are circumferentially arranged on the outer wall of the annular protrusion 27. The electromagnet 28 is magnetically connected to the ferromagnetic sheet 29. When it is necessary to adjust the states of the first clutch 10 and the second clutch 31, the first clutch 10 and the second clutch 31 are temporarily stopped from locking the first rotating cylinder 4 and the second rotating cylinder 5. In order to prevent the first rotating cylinder 4 and the second rotating cylinder 5 from rotating randomly, the electromagnet 28 is powered on to make the electromagnet 28 magnetically connected to the corresponding ferromagnetic sheet 29. During the rotation of the first rotating cylinder 4 and the second rotating cylinder 5, the annular protrusion 27 on the mounting shaft 26 also rotates in the mounting base 25. After the first rotating cylinder 4 and the second rotating cylinder 5 stop rotating, after the electromagnet 28 is magnetically connected to the corresponding ferromagnetic sheet 29, the first rotating cylinder 4 and the second rotating cylinder 5 are kept fixed. And a start-up power source capable of storing electricity is installed on the electromagnet 28, so that even if the power supply is insufficient, the electromagnet 28 can still be used normally.

[0030] The diesel driving mechanism 400 is in driving cooperation with the second rotating cylinder 5. The diesel driving mechanism 400 includes a diesel driving device 30. The diesel driving device 30 is arranged on the mounting support 1. A second clutch 31 is provided on the output end of the diesel driving device 30. An output shaft 11 is also provided on the second clutch 31. The output shaft 11 is fixedly connected to the mounting shaft 26 on the same side. After the power supply is insufficient, the first clutch 10 is kept in the neutral state. At this time, the output shaft 11 can rotate on the first clutch 10. Because the insertion shaft 13 meshes with the rotating collar 7, and the rotating collar 7 meshes with the rotating shaft 8. After the diesel driving device 30 is started, through the second clutch 31, the mounting shaft 26 is kept in a transmission relationship with the output end of the diesel driving device 30. The first rotating cylinder and the second rotating cylinder are driven to rotate synchronously by the diesel driving device 30, and the grinding operation of the gold ore material is continued. The diesel driving device 30 is a common diesel power device in the prior art and is a technical device well known to those skilled in the art. After generating mechanical energy by burning diesel, the output end of the diesel driving device 30 starts to rotate, and then drives the output shaft 11 and the mounting shaft 26 to rotate under the action of the second clutch 31. And a start-up power source capable of storing electricity is also provided on the diesel driving device 30. When the power supply is stopped, the diesel driving device 30 is started by the start-up power source.

[0031] Among them, through the meshing between the middle transmission mechanism 100 and the separable connection mechanism 200, it is used to keep the first rotating cylinder 4 and the second rotating cylinder 5 connected. When ensuring good power supply, insert the insertion shaft 13 into the insertion chamber 16 of the rotating ring sleeve 7, so that both the first rotating cylinder 4 and the second rotating cylinder 5 are meshed with the rotating ring sleeve 7. At this time, keep the second clutch 31 in the neutral position. After filling the first rotating cylinder 4 and the second rotating cylinder 5 with gold ore materials and steel balls, start the motor driving device 9 to drive the rotating ring sleeve 7, the first rotating cylinder 4 and the second rotating cylinder 5 to rotate, so that the materials and steel balls are ground in the first rotating cylinder 4 and the second rotating cylinder 5. After the power supply fails, keep the first clutch 10 in the neutral position, and then start the diesel driving device 30 to drive the first rotating cylinder 4 and the second rotating cylinder 5 to rotate, so that the first rotating cylinder 4 and the second rotating cylinder 5 continue to grind the gold ore materials. During the use process, even when any one of the two driving energy sources of electric energy or diesel is insufficient, the other separate driving energy source can independently drive the first rotating cylinder 4 and the second rotating cylinder 5 to ensure the continuity of the gold ore grinding operation.

[0032] Both the first rotating cylinder 4 and the second rotating cylinder 5 are octagonal. The first rotating cylinder 4 and the second rotating cylinder 5 are made of NM450 material steel plates as a whole. The material itself has the characteristics of high hardness, impact resistance and high wear resistance. Therefore, there is no need to install liners inside the first rotating cylinder 4 and the second rotating cylinder 5. The inner walls of the first rotating cylinder 4 and the second rotating cylinder 5 are smooth without seams, and the recovery rate of ore powder discharge is higher. Because there are eight concave corners inside the first rotating cylinder 4 and the second rotating cylinder 5, when the first rotating cylinder 4 and the second rotating cylinder 5 rotate, the gold ore raw materials and steel balls are more likely to be scooped up higher through the concave corners. Therefore, the impact of the steel balls on the ore raw materials is more uniform and sufficient, so the particle size uniformity and production efficiency are higher. Both the first rotating cylinder 4 and the second rotating cylinder 5 are symmetrically provided with inlets and outlets. A closed cover 32 is arranged inside the inlets and outlets. The gold ore materials and steel balls to be ground are filled into the first rotating cylinder 4 and the second rotating cylinder 5 through one of the inlets and outlets. After the grinding operation of the gold ore is completed, the gold ore and steel balls are discharged from the first rotating cylinder 4 and the second rotating cylinder 5 through the lower inlet and outlet. The closed cover 32 can keep the inside of the first rotating cylinder 4 and the second rotating cylinder 5 closed and also prevent the problem of material leakage during the rotation of the first rotating cylinder 4 and the second rotating cylinder 5.

[0033] A blanking chute body 33 is arranged in the middle of the mounting support 1. The mounting bracket 3 is fixedly connected to the middle of the blanking chute body 33. After the ground gold ore is discharged, it falls onto the blanking chute body 33, which is convenient for collecting the gold ore.

[0034] The working principle of this small double-power gold ore grinding ball mill: When ensuring a good power supply, insert the insertion shaft 13 into the insertion chamber 16 of the rotating ring sleeve 7 so that both the first rotating cylinder body 4 and the second rotating cylinder body 5 are engaged with the rotating ring sleeve 7. At this time, keep the second clutch 31 in the neutral position. After filling the first rotating cylinder body 4 and the second rotating cylinder body 5 with gold ore materials and steel balls, start the motor driving device 9 to drive the rotating ring sleeve 7, the first rotating cylinder body 4 and the second rotating cylinder body 5 to rotate, so that the materials and steel balls are ground in the first rotating cylinder body 4 and the second rotating cylinder body 5. After the power supply malfunctions, keep the first clutch 10 in the neutral position, and then start the diesel driving device 30 to drive the first rotating cylinder body 4 and the second rotating cylinder body 5 to rotate, so that the first rotating cylinder body 4 and the second rotating cylinder body 5 continue to grind the gold ore materials. During use, even when there is a shortage of any one of the two driving energy sources, namely electric energy or diesel, the other separate driving energy source can independently drive the first rotating cylinder body 4 and the second rotating cylinder body 5 to ensure the continuity of the gold ore grinding operation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
