Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment, and in particular to a mineral processing equipment for improving the gold recovery rate of gold ore. Background Technology

[0002] A mineral processing unit is a system composed of multiple devices used to separate and purify ores based on differences in their physical and chemical properties. The use of mineral processing units that improve gold recovery rates is essential because gold, as a vital strategic resource, has limited reserves. Improving recovery rates allows for efficient resource utilization, especially in processing low-grade, difficult-to-process gold ores, increasing gold production and economic benefits for enterprises. Simultaneously, it reduces tailings emissions to protect the environment, promotes advancements in mineral processing technology, and adapts to market demands and industry development trends.

[0003] The existing mineral processing equipment for improving gold recovery rate mainly works by first crushing and grinding the gold-bearing ore to liberate the gold minerals, then adding flotation reagents and introducing air to form bubbles, causing the gold minerals to adhere to the bubbles and form a foam layer. At the same time, gravity separation and other methods are used to further improve the recovery rate. Auxiliary means such as classification equipment, intelligent control system and tailings reprocessing are also used to improve the gold recovery rate.

[0004] However, a problem exists in the actual use of mineral processing equipment to improve gold recovery rates: when crushing ores of different sizes, different types of crushers are required due to the diversity of ores. This increases the investment cost of the equipment, as multiple different crushers need to be purchased, and also makes the entire mineral processing process more complex and cumbersome, requiring operators to frequently switch and adjust different crushers. In summary, this problem significantly affects the practicality of mineral processing equipment for improving gold recovery rates. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a mineral processing device for improving gold ore recovery rate, comprising a crushing box 1, a crushing plate 2 slidably connected inside the crushing box 1 for crushing incoming raw materials, an eccentric shaft 3 rotatably connected to the top of the crushing plate 2 for driving the crushing plate 2 to crush, a transmission wheel 4 fixedly connected to one end of the eccentric shaft 3 for transmitting power, a support plate 7 fixedly connected inside the crushing box 1, a dustproof box 8 fixedly connected to the top of the support plate 7 for preventing dust from entering the motor 9 and affecting its operation, and a drive wheel 6 provided on one side of the dustproof box 8 for transmitting power. A belt 5 is provided between the driving wheel 4 and the driving wheel 6 to drive the driving wheel 6 and the transmission wheel 4. A motor 9 is fixedly connected inside the dustproof box 8 to drive the crusher. The output end of the motor 9 is connected to the driving wheel 6. A fixed plate 12 is fixedly connected inside the crushing box 1. A limit component is provided on one side of the support plate 7. Multiple connecting strips 13 are rotatably connected to one side of the fixed plate 12 to limit the movement range of the crushing plate 2. A telescopic component is provided inside the crushing box 1. Multiple sliding grooves 17 are opened on one side of the crushing box 1. A discharge box 18 is fixedly connected to the bottom of the crushing box 1 to discharge the crushed raw materials.

[0033] The telescopic assembly includes a second crushing plate 14, multiple hydraulic rods 15, and multiple sliding columns 16. The second crushing plate 14 is slidably connected to both sides inside the crushing box 1 to limit the crushing range. One end of each hydraulic rod 15 is fixedly connected to the inside of the crushing box 1 to control the movement of the second crushing plate 14. The output end of each hydraulic rod 15 is connected to one side of the second crushing plate 14. One end of each sliding column 16 is fixedly connected to both sides of the second crushing plate 14, and the outer wall of each sliding column 16 is slidably connected to the inside of the sliding groove 17. The limiting assembly includes a telescopic rod 10 and a spring 11. One end of the telescopic rod 10 is rotatably connected to one side of the support plate 7, and the other end of the telescopic rod 10 is fixedly connected to the bottom of the first crushing plate 2 to limit the movement range of the first crushing plate 2. The spring 11 is disposed on the outer wall of the telescopic rod 10 to provide a rebound force. One end of the spring 11 is fixedly connected to one side of the support plate 7, and the other end of the spring 11 is fixedly connected to the outer wall of the telescopic rod 10.

[0034] Specifically, during the operation of the mineral processing unit, when encountering raw materials that are too large, these large materials may get stuck between the two crushing plates, causing obstruction to the operation of the equipment. At this time, it is necessary to adjust the distance between the second crushing plate 14 and the first crushing plate 2 by driving the hydraulic rod 15. During this adjustment process, the sliding column 16 can be seen to slide smoothly inside the sliding groove 17 until it slides to the required position and then is fixed. Through this operation, the two crushing plates that were originally tightly stuck with the raw material can slowly loosen the raw material, relieve the jamming state of the equipment, and then the crushing program can be restarted again, so that the raw material can be crushed into the required size more efficiently between the adjusted crushing plates, thereby ensuring the smooth progress of the entire mineral processing process.

[0035] Reference Figure 1 , Figure 3 and Figure 4 A screening box 19 is provided at the bottom of the discharge box 18. A rotating shaft 20 is rotatably connected inside the screening box 19 to drive the filter cylinder to rotate. Multiple support bars 21 are fixedly connected to the outer wall of the rotating shaft 20 to support the filter cylinder. A fixing ring 22 is fixedly connected to one end of the support bar 21 to fix the filter screen 28. A connecting block 23 is slidably connected inside the fixing ring 22 to fix the fixing bar 25 and the fixing bar 27. The fixing bar 25 is fixedly connected inside the fixing ring 22. A connecting ring 26 is slidably connected to one side of the fixing ring 22 to connect the filter screen 28. A spring 24 is provided inside the fixing ring 22 to provide pressure to the connecting block 23. Supporting force: one end of spring 24 is fixedly connected to the inside of the fixed ring 22, and the other end of spring 24 is fixedly connected to the bottom of the connecting block 23. A fixing strip 27 is fixedly connected inside the connecting ring 26. A filter screen 28 is fixedly connected to one side of the connecting ring 26 for filtering the crushed raw materials. A dustproof box 29 is fixedly connected to one side of the screening box 19. A motor 30 is fixedly connected inside the dustproof box 29 for driving the filter cartridge to rotate. The output end of the motor 30 is connected to one end of the rotating shaft 20. The connecting strips 13 are arranged in a parallel array and rotatably connected to one side of the fixed plate 12. The hydraulic rods 15 are arranged in a ring array and fixedly connected inside the crushing box 1.

[0036] Specifically, when the filter 28 needs to be replaced, the operator first presses the filter 28. Under the application of a certain external force, the filter 28 will gradually deform. As the filter 28 deforms, it will drive the connecting ring 26 to move slowly inward, causing the connecting block 23 to move downward in a specific direction. During the downward movement of the connecting block 23, the fixing strip 1 25 and fixing strip 27 will be separated. Through this series of actions, the locking state between the connecting ring 26 and the fixing ring 22 can be released. Then, after the fixing structures in all four directions are successfully unlocked in the same way, the operator can remove the filter 28. Then, simply place the new filter 28 in the original position and follow the reverse steps to relock the connecting ring 26 and the fixing ring 22, and fix the fixing structures in all four directions again, thus completing the replacement of the filter 28.

[0037] Working principle: In the process of using the mineral processing device to improve the gold recovery rate of gold ore, first adjust the distance between the two crushing plates. The distance between crushing plate 14 and crushing plate 2 is adjusted by driving the hydraulic rod 15, thereby allowing the sliding column 16 to slide into the sliding groove 17 and be fixed in the required position. Then, replace the required filter screen 28 on the equipment. First, press one side of the filter screen 28 to cause a certain deformation, thereby causing it to drive the connecting ring 26 inward. This causes the connecting block 23 to move downward, separating the fixing strip 25 and the fixing strip 27, thus connecting the... Unlock the connection between the connecting ring 26 and the fixed ring 22, and then unlock the four fixed structures in sequence to remove the old filter screen 28. Then, install the new filter screen 28 to complete the replacement. Then, start the motor 9 to drive the drive wheel 6 to rotate, which in turn drives the transmission wheel 4 to rotate via the belt 5 wound around it. This drives the eccentric shaft 3 to rotate, causing the crushing plate 2 to vibrate and crush the raw material. At the same time, start the motor 30 to drive the rotating shaft 20 to rotate, which in turn causes the filter screen 28 to rotate, so that the incoming raw material is screened by the action of the filter screen 28.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
