Abstract

The utility model provides a gold sorting device for mineral separation, and belongs to the technical field of gold sorting. The device comprises a box body, a sorting assembly is arranged in the box body, and the top of the box body is connected with a feeding hopper. The interior of the feeding hopper comprises a material guide groove communicating with an inner cavity of the box body, a material storage groove communicating with the side wall of the material guide groove, a sealing plate arranged in the material guide groove and a driving assembly connected with the sealing plate. The outer side wall of the sealing plate is attached to the inner wall of the guide groove, and the driving assembly is used for driving the sealing plate to move in the axial direction of the guide groove. By means of the mode, in the process that the driving assembly drives the sealing plate to move in the axial direction of the material guide groove, when the sealing plate moves to the bottom of the material storage groove, mineral aggregate in the feeding hopper enters the material storage groove, then the sealing plate is rapidly lifted to the position above the material storage groove, and then the mineral aggregate in the material storage groove can be discharged. Due to the fact that the size of the material storage groove is fixed, the amount of ore materials discharged every time is almost the same, accurate control over the discharging amount of the ore materials is achieved, and the gold separation effect is further improved.

Description

Technical Field

[0001] This application relates to the field of gold sorting technology, specifically to a gold sorting device for mineral processing. Background Technology

[0002] Gold is not only a special currency used for storage and investment, but also an important material in the jewelry industry, electronics industry, modern communications, aerospace industry and other fields. It is one of the rarest, most precious and widely watched metals today.

[0003] In the gold production process, gold sorting is a crucial step. Currently, gold sorting typically involves placing the ore directly into a feed hopper, which then feeds it onto a conveyor belt for transport and sorting. However, because the feed rate from the hopper is uncontrollable, excessive feed can easily lead to mixing of gold ore with ordinary ore. This makes it impossible to use gold panning grass to separate the gold ore from the ordinary ore, thus affecting the overall gold ore sorting efficiency. Summary of the Invention

[0004] In view of the technical problems existing in the background art, this application provides a gold sorting device for mineral processing, which can accurately control the amount of ore fed, thereby improving the sorting effect of gold ore.

[0005] This application provides a gold sorting device for mineral processing, including a housing; a sorting component is disposed inside the housing, and a feed hopper is connected to the top of the housing;

[0006] The interior of the feeding hopper includes a guide trough communicating with the inner cavity of the box, a storage trough communicating with the side wall of the guide trough, a sealing plate disposed in the guide trough, and a drive assembly connected to the sealing plate.

[0007] The outer wall of the sealing plate is in contact with the inner wall of the guide groove, and the driving assembly is used to drive the sealing plate to move axially along the guide groove.

[0008] In the technical solution of this application embodiment, a storage trough communicating with the side wall of the guide trough is set inside the feeding hopper, and a sealing plate with its outer wall abutting it is set inside the guide trough. During the process of the sealing plate moving axially along the guide trough using a drive assembly, when the sealing plate moves to the bottom of the storage trough, the ore in the feeding hopper can enter the storage trough. Then, the sealing plate is quickly lifted to the top of the storage trough, allowing the ore in the storage trough to be discharged into the box. With this setup, as the sealing plate moves back and forth, almost all the ore in the storage trough is discharged each time. Since the size of the storage trough is fixed, this ensures that the amount of ore discharged each time is almost consistent, achieving accurate control of the ore discharge amount, thereby improving the sorting effect of gold ore.

[0009] In some embodiments, the sorting assembly includes a conveyor belt disposed within the inner cavity of the housing; the conveyor belt is an inclined closed-loop structure, and the surface of the conveyor belt is provided with gold panning grass; the upper input end of the top surface of the conveyor belt is located below the outlet of the guide chute, and the lower output end of the top surface of the conveyor belt is located at the opening of the first collection box; a scraper is disposed inside the housing, one side of the scraper abuts against the bottom surface of the conveyor belt, and a second collection box is disposed on the side of the scraper near the first collection box.

[0010] In this embodiment, the ore falling through the guide chute will fall onto the conveyor belt. The gold ore in the ore will adhere to the gold panning grass, while the other ordinary ore will fall into the first collection box along the conveyor belt's conveying direction. The gold ore adhering to the gold panning grass will be scraped off by the scraper and fall into the second collection box, thus achieving the sorting of gold.

[0011] In some embodiments, the sorting assembly further includes a water spraying assembly for spraying water onto the top surface of the conveyor belt.

[0012] In this embodiment, by setting up a water spraying component, it is convenient for ordinary mineral materials with lower density to flow into the first collection box with the water flow.

[0013] In some embodiments, the first collection box is provided with a filter screen.

[0014] In this embodiment, by setting up a filter screen, it is easy to separate ordinary mineral materials from water as they flow into the first collection box, so that the water can be recycled.

[0015] In some embodiments, the water spray assembly includes a pump, a water supply pipe, and a nozzle; the input end of the pump is connected to the bottom of the first collection tank, the output end of the pump is connected to one end of the water supply pipe, the other end of the water supply pipe is connected to the nozzle, and the nozzle is located above the top surface of the conveyor belt.

[0016] In this embodiment, by connecting the pump to the first collection tank, the water in the first collection tank can be transported to the nozzle through the water supply pipe, sprayed onto the conveyor belt, and then flowed back to the first collection tank, thus realizing the recycling of water.

[0017] In some embodiments, the drive assembly includes a drive motor, a threaded rod connected to the output end of the drive motor, and a threaded cylinder connected to the threaded rod; the axial direction of the threaded rod and the threaded cylinder is aligned with the axial direction of the guide groove, and the bottom of the threaded cylinder is connected to the top of the sealing plate.

[0018] In this embodiment, the threaded rod can rotate under the drive of the drive motor, and the threaded cylinder moves along the axial direction of the threaded rod as the threaded rod rotates, thereby driving the sealing plate to move along the axial direction of the guide groove.

[0019] In some embodiments, the top of the feed hopper is provided with a mounting bracket for fixing the drive motor.

[0020] In this embodiment, a fixing frame is provided to facilitate the fixing of the drive motor, thereby ensuring the stability of the driving process.

[0021] In some embodiments, a guide rod is provided at the bottom of the fixing frame, and the axial direction of the guide rod is consistent with the axial direction of the threaded cylinder; a guide cylinder is sleeved on the outer side of the guide rod and slidably connected to the guide rod, and the side wall of the threaded cylinder is connected to the guide cylinder.

[0022] In this embodiment, by setting a guide rod and a guide cylinder, the threaded cylinder is easily guided to ensure that it moves axially.

[0023] In some embodiments, a cavity is provided on the side of the storage tank away from the guide trough; a telescopic rod is provided in the cavity, and a pusher plate is provided at the telescopic end of the telescopic rod; the telescopic direction of the telescopic rod is perpendicular to the axial direction of the guide trough, and the pusher plate is located in the cavity on the side closer to the storage tank.

[0024] In this embodiment, by setting a telescopic rod and a pusher plate, when the ore in the storage tank cannot fall naturally, the telescopic rod is extended by driving it to push the ore out of the storage tank using the pusher plate, so as to ensure that the ore in the storage tank can be completely discharged, and further ensure the accuracy of the feeding amount.

[0025] In some embodiments, the inner wall of the enclosure is provided with sound insulation cotton.

[0026] In this embodiment, sound-absorbing cotton is used to reduce the noise generated during gold sorting.

[0039] To address the problem of traditional gold sorting devices' inability to effectively control the amount of material discharged from the feed hopper 3, this application provides a gold sorting device for mineral processing. This device features a storage trough 9 connected to the side wall of a guide trough 8 inside the feed hopper 3. A sealing plate 10, with its outer wall abutting the guide trough 8, is installed inside the guide trough 8. As the sealing plate 10 moves axially along the guide trough 8 using a drive assembly, when it reaches the bottom of the storage trough 9, the ore in the feed hopper 3 enters the storage trough 9. Then, the sealing plate 10 is quickly lifted above the storage trough 9, discharging the ore from the storage trough 9 into the housing 1. With this configuration, the ore in the storage trough 9 is almost always discharged with each reciprocating movement of the sealing plate 10. Since the size of the storage trough 9 is fixed, this ensures that the amount of ore discharged each time is almost consistent, achieving accurate control of the ore discharge amount and thus improving the sorting effect of gold ore.

[0040] Please refer to Figure 1 , Figure 3 The gold sorting device for mineral processing provided in this application includes a housing 1; a sorting component 2 is provided inside the housing 1, and a feed hopper 3 is connected to the top of the housing 1;

[0041] The interior of the feed hopper 3 includes a guide trough 8 that communicates with the inner cavity of the housing 1, a storage trough 9 that communicates with the side wall of the guide trough 8, a sealing plate 10 disposed in the guide trough 8, and a drive assembly connected to the sealing plate 10.

[0042] The outer wall of the sealing plate 10 is in contact with the inner wall of the guide groove 8, and the drive assembly is used to drive the sealing plate 10 to move axially along the guide groove 8.

[0043] In the above manner, as the drive assembly moves the sealing plate 10 axially along the guide trough 8, when the sealing plate 10 moves to the bottom of the storage trough 9, the ore in the feed hopper 3 will enter the storage trough 9. Then, the sealing plate 10 is quickly lifted to the top of the storage trough 9, causing the ore in the storage trough 9 to fall out. This ensures that the amount of material discharged each time is basically consistent with the volume of the storage trough 9, thereby achieving accurate control of the discharge amount. It should be noted that the sealing plate 10 moves at a relatively fast speed during its movement, so that the sealing plate 10 is in the middle of the storage trough 9 for a short time, effectively reducing the amount of material leakage at that position. Therefore, a small amount of leakage will not have a significant impact on the discharge amount, and since the speed of the sealing plate 10 is constant each time, the amount of leakage each time is not significantly different, so the final discharge amount can still remain basically consistent each time. Based on the device in this application, the volume of the storage tank 9 only needs to be designed according to the required amount of material to be fed during sorting, so as to accurately control the amount of material fed each time, thereby avoiding the problem that the gold mining grass is unable to effectively sort gold ore and ordinary ore due to excessive material feeding.

[0044] Furthermore, in the embodiments of this application, such as Figure 1 As shown, the sorting component 2 includes a conveyor belt 21 disposed in the inner cavity of the housing 1; the conveyor belt 21 is an inclined closed-loop structure, and the surface of the conveyor belt 21 is provided with gold panning grass; the upper input end of the top surface of the conveyor belt 21 is located below the outlet of the guide chute 8, and the lower output end of the top surface of the conveyor belt 21 is located at the opening of the first collection box 22; a scraper 24 is disposed inside the housing 1, one side of the scraper 24 abuts against the bottom surface of the conveyor belt 21, and a second collection box 25 is disposed on the side of the scraper 24 near the first collection box 22.

[0045] In this manner, the ore falling through the guide chute 8 will land on the conveyor belt 21. Gold ore will adhere to the gold-digging grass, while other ordinary ore will fall into the first collection box 22 as the conveyor belt 21 moves in the same direction. Simultaneously, when the conveyor belt 21 at the top moves to the bottom, the scraper 24, with its side in contact with the bottom, can scrape off the gold ore adhering to the gold-digging grass. The scraped-off gold ore will fall into the second collection box 25 for collection, thus achieving the sorting of gold.

[0046] Furthermore, in this embodiment, the sorting component 2 also includes a water spraying component for spraying water onto the top surface of the conveyor belt 21, so as to promote the entry of ordinary minerals with lower density into the first collection box 22 along with the water flow.

[0047] Furthermore, in this embodiment, a filter screen 23 is provided in the first collection tank 22. This filter screen 23 separates ordinary mineral materials from the water flowing into the first collection tank 22, allowing for water recycling. In this embodiment, the water spray assembly includes a pump 26, a water pipe 27, and a nozzle. The input end of the pump 26 is connected to the bottom of the first collection tank 22, the output end of the pump 26 is connected to one end of the water pipe 27, and the other end of the water pipe 27 is connected to the nozzle, which is located above the top surface of the conveyor belt 21. With this configuration, the pump 26 can draw water from the first collection tank 22, transport it through the water pipe 27 to the nozzle, spray it onto the conveyor belt 21, and then flow back to the first collection tank 22. After being filtered by the filter screen 23, the water enters the bottom of the first collection tank 22 and can then be drawn out again by the pump 26, thus achieving water recycling.

[0048] Furthermore, please refer to the following: Figure 1 , Figure 2 In this embodiment, the driving assembly includes a drive motor 5, a threaded rod 6 connected to the output end of the drive motor 5, and a threaded cylinder 7 connected to the threaded rod 6. The axial directions of the threaded rod 6 and the threaded cylinder 7 are aligned with the axial direction of the guide groove 8, and the bottom of the threaded cylinder 7 is connected to the top of the sealing plate 10. With this configuration, the threaded rod 6 can rotate under the drive of the drive motor 5, and the threaded cylinder 7 moves along the axial direction of the threaded rod 6 as it rotates, thereby driving the sealing plate 10 to move along the axial direction of the guide groove 8. The drive motor 5 can rotate forward and reverse to drive the sealing plate 10 to move upward and downward, respectively.

[0049] Furthermore, in this embodiment, a mounting bracket 4 for fixing the drive motor 5 is provided at the top of the feed hopper 3 to ensure the stability of the driving process; a guide rod 13 is also provided at the bottom of the mounting bracket 4, the axial direction of the guide rod 13 being consistent with the axial direction of the threaded cylinder 7; a guide cylinder 14 slidably connected to the guide rod 13 is sleeved on the outer side of the guide rod 13, and the side wall of the threaded cylinder 7 is connected to the guide cylinder 14. This arrangement facilitates the guidance of the threaded cylinder 7, ensuring that the threaded cylinder 7 moves along the axial direction of the guide rod 13, and since the axial direction of the guide rod 13 is consistent with the axial direction of the threaded cylinder 7 and the guide groove 8, the axial movement of the threaded cylinder 7 can be guaranteed.

[0050] Furthermore, please refer to the following: Figure 3In this embodiment, a cavity is provided on the side of the storage tank 9 away from the guide tank 8; a telescopic rod 11 is provided in the cavity, and a pusher plate 12 is provided at the telescopic end of the telescopic rod 11; the telescopic direction of the telescopic rod 11 is perpendicular to the axial direction of the guide tank 8, and the pusher plate 12 is located on the side of the cavity closer to the storage tank 9. With this configuration, when the ore in the storage tank 9 cannot fall naturally, the ore in the storage tank 9 can be pushed out by the pusher plate 12 by driving the telescopic rod 11 to ensure that the ore in the storage tank 9 can be completely discharged, further ensuring the accuracy of the discharge amount. Preferably, the telescopic rod 11 is an electrically operated telescopic rod for easy control.

[0051] Furthermore, in this embodiment of the application, the inner wall of the box 1 is provided with sound insulation cotton 15 in order to reduce the noise generated during gold sorting.

[0052] Please refer to the following: Figures 1 to 3 According to one or more embodiments of this application, the working process of the gold sorting device for mineral processing provided in this application includes:

[0053] The ore is added to the feed hopper 3, causing the drive motor 5 to rotate forward, which in turn drives the threaded rod 6 to rotate forward. This causes the threaded rod 6 to move the threaded cylinder 7 and the sealing plate 10 connected to the threaded cylinder 7 downward to the bottom of the storage trough 9. At this time, the ore in the feed hopper 3 will enter the storage trough 9. Then, the drive motor 5 is reversed, causing the threaded rod 6 to rotate in the opposite direction. This causes the threaded rod 6 to move the threaded cylinder 7 and the sealing plate 10 upward to the top of the storage trough 9, allowing the ore in the storage trough 9 to fall onto the conveyor belt 21 through the guide trough 8. When the sealing plate 10 moves to the top of the storage trough 9, in order to ensure that the ore in the storage trough 9 falls completely, the telescopic rod 11 can be driven to extend outward, causing the pusher plate 12 to completely push out the ore in the storage trough 9.

[0054] During the sorting process, a certain amount of water can be first filled into the first collection box 22. A pump 26 draws water from the first collection box 22 and sprays it onto the conveyor belt 21 through nozzles 28. During the transport process on the conveyor belt 21, gold ore adheres to the gold-draining grass, while other, less dense ordinary ore flows with the water into the first collection box 22. There, it is filtered through the filter screen 23, leaving the ordinary ore on the filter screen 23, while the water flows through the filter screen 23 to the bottom of the first collection box 22 for reuse. When the gold ore adhering to the gold-draining grass moves along the conveyor belt 21 to the location of the scraper 24, it is scraped off by the scraper 24 and collected in the second collection box 25. This completes the gold sorting process.

[0055] In summary, this application provides a gold sorting device for mineral processing, belonging to the field of gold sorting technology. The device includes a housing 1; a sorting assembly 2 is disposed inside the housing 1, and a feed hopper 3 is connected to the top of the housing 1; the feed hopper 3 includes a guide trough 8 communicating with the inner cavity of the housing 1, a storage trough 9 communicating with the side wall of the guide trough 8, a sealing plate 10 disposed within the guide trough 8, and a drive assembly connected to the sealing plate 10; the outer side wall of the sealing plate 10 is in contact with the inner wall of the guide trough 8, and the drive assembly drives the sealing plate 10 to move axially along the guide trough 8. Through this method, as the drive assembly moves the sealing plate 10 axially along the guide trough 8, when the sealing plate 10 moves to the bottom of the storage trough 9, the ore in the feed hopper 3 enters the storage trough 9, and then the sealing plate 10 is quickly lifted above the storage trough 9, allowing the ore in the storage trough 9 to be discharged. Since the size of the storage tank 9 is fixed, the amount of ore fed each time is almost the same, which achieves accurate control of the amount of ore fed, thereby improving the gold sorting effect.

[0056] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
