Description

Technical Field

[0001] This utility model relates to the field of ore sorting technology, and in particular to an automatic gold ore sorting device. Background Technology

[0002] Gravity differences can be used to separate gold ore from gangue, thereby improving the purity of the final gold ore, shortening the time for subsequent production and processing, and increasing the efficiency of gold ore processing.

[0003] Traditional sorting equipment mostly uses flotation, which requires the gold ore to be thoroughly ground and reagents to be added for flotation. Gravity sorting equipment mostly uses directional water flow to wash the gold ore in an open environment, which has low operating efficiency and poor sorting effect, affecting the final sorting effect of the gold ore. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic gold ore sorting device that can improve gold ore sorting efficiency and increase the purity and grade of the final gold ore.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic gold ore sorting device includes a support frame, inside which a rotating sorting drum is installed. A liquid guiding pipe is horizontally arranged inside the sorting drum, penetrating the axis of the sorting drum. Multiple separating rings are arranged inside the sorting drum, and a sorting area is formed between two adjacent separating rings. A flow-turbulence device is sleeved on the outside of the liquid guiding pipe, and the flow-turbulence device is located in the corresponding sorting area. The flow-turbulence device includes a deflection ring sleeved on the outside of the liquid guiding pipe, and a connecting pipe is fixed to the bottom of the deflection ring. A fan-shaped flow-turbulence component is fixed to the bottom of the connecting pipe. The bottom of the fan-shaped flow-turbulence component has a first nozzle and a second nozzle. The flow-turbulence device is connected to the liquid guiding pipe by a torsional elastic component.

[0007] Preferably, the deflection ring has a sandwiched chamber inside, the sandwiched chamber has a flow-guiding opening on the side near the liquid guiding pipe, and the liquid guiding pipe has a second drain opening on its surface, the second drain opening being located on the deflection path of the flow-guiding opening.

[0008] Preferably, both the flow guiding opening and the second drainage opening are strip-shaped openings and their length directions are the same.

[0009] Preferably, the connecting pipe has an internal chamber, the top of which is connected to the interlayer chamber, and the bottom of which is connected to the first nozzle and the second nozzle.

[0010] Preferably, a support frame is fixed to the outside of the carrier frame, and the liquid guiding pipe is supported and fixed by the support frame.

[0011] Preferably, the torsion elastic component includes a positioning ring fixedly connected to the liquid guiding pipe, and the positioning ring and the deflection ring are connected by a torsion elastic element.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] By incorporating structures such as sorting drums, liquid guiding pipes, and turbulence devices, gravity separation of gold ore and gangue can be achieved using buoyancy. The sorting solution can flow directionally within the sorting drum, carrying away the floating gangue during this directional flow. The turbulence device can spray liquid from the bottom to accelerate the floating of gangue, further improving the sorting effect of gangue, increasing the gold ore sorting efficiency, and ultimately improving the purity and grade of the gold ore.

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0025] See attached document Figure 1 - Appendix Figure 8 The continuous gold ore sorting process is used to separate high-density gold ore from low-density gangue. An automatic gold ore sorting device is used. Before sorting, the gold ore containing gangue is ground into a preset particle size and prepared into a gold slurry. The gold slurry is then fed into the automatic gold ore sorting device for sorting.

[0026] Specifically, the automatic gold ore sorting device includes a support frame 100, on which a support frame 110 is fixed. A sorting drum 200 is rotatably connected inside the support frame 100. Multiple separating rings 210 are fixed at intervals inside the sorting drum 200. A sorting area 2101 is formed between two adjacent separating rings 210 to accommodate the gold ore slurry. A feeding pipe 500 is provided on the first side of the sorting drum 200. The gold ore slurry is fed into the sorting drum 200 for sorting through the feeding pipe 500. The feeding pipe 500 is rotatably and sealed to the axis of the sorting drum 200, ensuring normal feeding of the ore slurry while allowing the sorting drum 200 to rotate in a specific direction or swing back and forth.

[0027] A liquid guiding pipe 300 is also provided at the axis of the sorting drum 200. The sorting solution can be introduced into the sorting drum 200 through the liquid guiding pipe 300, and the direction of the sorting solution can be controlled. The flowing sorting solution can carry gangue out of the sorting drum 200, while the denser gold ore cannot cross the separating ring 210 and remains in the sorting area 2101, thus achieving the separation of gold ore and gangue.

[0028] The preferred separation solutions are calcium chloride or magnesium chloride solutions, as these solutions have a higher density and will not affect gold separation. The density of the prepared solution should be controlled within the range of 1.2-1.45 g / cm³, which can increase the buoyancy of the gangue and accelerate its flotation efficiency in the separation solution, achieving efficient separation, while avoiding excessive concentration that could affect the normal settling of ore particles. In addition, the same high-density solution should be used in the preparation of the gold slurry to ensure the consistency and stability of the separation.

[0029] The aforementioned liquid guiding pipe 300 also passes through the axis of the sorting drum 200. Its first side is connected and fixed to the support frame 100 through the support frame 110, and its second side passes through the feeding pipe 500 and extends to the outside. The feeding pipe 500 here is a sandwich design, including an outer sleeve 530 located on the outermost side and an inner sleeve 510 located on the inner side. The inner sleeve 510 and the outer sleeve 530 are fixedly connected by multiple spaced connecting components 520. This structure can ensure that the gold slurry can pass through normally, and can also achieve relative isolation and sealing by the inner sleeve 510 being fitted on the outside of the liquid guiding pipe 300, thus ensuring the normal flow of the gold slurry.

[0030] The sorting drum 200 here is open on one side and closed on the other: the side closer to the feed pipe 500 is closed, and the side farther away from the feed pipe 500 is open. The open side allows the sorting solution and gangue to flow out. During the sorting process, the gold ore slurry must first be fed into the closed side of the sorting drum 200 through the feed pipe 500, and then the sorting solution is fed into the corresponding position through the liquid guiding pipe 300. The sorting solution is controlled to flow in a specific direction within the sorting drum 200. During the flow, gangue with lower density will float to the surface and be discharged with the sorting solution.

[0031] A first drain opening 310 is provided on the surface of the liquid guiding pipe 300. The sorting solution can be discharged to the corresponding position inside the sorting drum 200 through the first drain opening 310. At the same time, the first drain opening 310 is located on the side close to the feeding pipe 500. When the gold ore slurry is fed, the sorting solution can be controlled to spray out from the first drain opening 310, forming turbulence on the gold ore slurry and further improving the sorting effect of the gold ore slurry.

[0032] To further improve the sorting effect of gold ore slurry in each sorting zone 2101 within the sorting drum 200, multiple turbulence devices 400 are also installed inside the sorting drum 200. These multiple turbulence devices 400 are opposite to the corresponding sorting zones 2101, which can both disturb the ore at the bottom of the sorting zone 2101, accelerate the floating of gangue to improve sorting efficiency, and reduce the flow rate of the sorting solution to reduce resource loss.

[0033] Specifically, the turbulence device 400 includes a deflection ring 410 sleeved on the outside of the liquid guiding pipe 300. A connecting pipe 440 is fixed to the bottom of the deflection ring 410, and a fan-shaped turbulence component 450 is fixed to the bottom of the connecting pipe 440. The fan-shaped turbulence component 450 has a fan-shaped structure and is set in the sorting area 2101. It can disturb the ore. Especially when the sorting drum 200 rotates in a direction, the fan-shaped turbulence component 450 is located on the path of ore tumbling, which can form local turbulence, improve the sorting effect of ore in the slurry, and accelerate the separation of gangue and gold ore.

[0034] The aforementioned deflection ring 410 and the liquid guiding pipe 300 are preferentially connected through a torsion elastic component. When there is a large amount of gold ore in the sorting area 2101, the fan-shaped turbulence component 450 can deflect synchronously with the ore and automatically reset under the action of the torsion elastic component.

[0035] The aforementioned torsional elastic component includes a positioning ring 430 fixedly connected to the outer wall of the liquid guiding pipe 300, and a torsional elastic element 420 disposed between the positioning ring 430 and the deflection ring 410. With the positioning ring 430 as a reference, the torsional elastic element 420 can drive the deflection ring 410, which has been deflected to the outer position, to return to its original position. In a static state, the deflection ring 410 and the connecting pipe 440 and the fan-shaped turbulence assembly 450 below it will be in a predetermined position and facing the bottom of the sorting area 2101.

[0036] To further enhance the turbulence effect on the ore in the sorting area 2101, a first nozzle 451 and a second nozzle 452 are provided at the bottom of the fan-shaped turbulence assembly 450. The tops of the first nozzle 451 and the second nozzle 452 are located in the middle position, and the bottoms radiate outwards. They can spray liquid to create turbulence on the slurry in the sorting area 2101, further accelerating the floating of gangue.

[0037] The aforementioned connecting pipe 440 has an internal chamber 441 inside. The deflection ring 410 is hollow and has an internal interlayer chamber 411 that communicates with the internal chamber 441. A flow guide opening 412 is provided on the side wall of the interlayer chamber 411, and the flow guide opening 412 communicates with the inside of the liquid guiding pipe 300. The sorting solution in the liquid guiding pipe 300 can pass through the flow guide opening 412, the interlayer chamber 411, and the internal chamber 441 in sequence, and finally be discharged from the first nozzle 451 and the second nozzle 452, thereby realizing multi-position turbulence of the sorting solution and improving the gangue sorting effect.

[0038] In order to adaptively adjust the amount of sorting solution sprayed from the first nozzle 451 and the second nozzle 452 according to the size of the solid particles in the slurry in the sorting area 2101, and to achieve targeted sorting turbulence control, a second drain opening 320 is opened at the bottom of the liquid guiding pipe 300. The aforementioned guiding opening 412 is located on the side wall of the interlayer chamber 411. When the connecting pipe 440 is in a vertical state, the second drain opening 320 and the guiding opening 412 only overlap slightly, allowing only a small portion of the sorting solution to pass through and be sprayed out from the first nozzle 451 and the second nozzle 452.

[0039] When the amount of solid impurities in the slurry increases in the sorting zone 2101, during the process of the slurry and ore being directionally deflected by the sorting drum 200, the excess ore will impact the fan-shaped turbulence component 450, causing the fan-shaped turbulence component 450 to deflect. As the deflection angle of the fan-shaped turbulence component 450 increases, the overlapping area of ​​the guide opening 412 and the second drain opening 320 will increase simultaneously, and the passage area of ​​the sorting solution will also increase. At this time, the flow velocity of the sorting solution sprayed from the interlayer chamber 411 and the first nozzle 451 and the second nozzle 452 will increase, forming a stronger turbulence in the sorting zone 2101, further improving the sorting effect of gangue.

[0040] Through the above structural design, the turbulence effect of the turbulence device 400 can be automatically adjusted according to the distribution of the gangue in multiple sorting areas 2101. Moreover, there is no need to design too many sensing elements. Automatic adjustment can be achieved by simply using the impact of the gangue. The structure is simple and the effect is significant, which greatly improves the sorting effect and efficiency of gangue.

[0041] The aforementioned flow guide opening 412 and the second drainage opening 320 both have strip-shaped horizontal projection surfaces, which can form different overlapping areas depending on the deflection angle of the deflection ring 410. In addition, the fixed position of the positioning ring 430 can be deflected and adjusted. By changing the overlapping area of ​​the flow guide opening 412 and the second drainage opening 320 in the initial state, the initial turbulence effect of the fan-shaped turbulence component 450 can be adjusted to meet the sorting requirements of different types of ores.

[0042] The gold ore is continuously sorted according to the following steps:

[0043] Step 1: The gold ore slurry is fed into the sorting drum 200 through the feed pipe 500, and the sorting solution is fed into the sorting drum 200 through the liquid guide pipe 300. Both the gold ore slurry and the sorting solution enter from the closed side of the sorting drum 200, and excess sorting solution flows from the closed side of the sorting drum 200 to the open side.

[0044] Step 2: During the flow of the sorting solution, the sorting drum 200 is controlled to rotate continuously or oscillate back and forth; during this process, the gangue with lower density will float to the surface and eventually flow out from the open side of the sorting drum 200 with the sorting solution.

[0045] Step 3: While the sorting drum 200 continues to rotate or oscillates back and forth, control the bottom of the turbulence device 400 to spray out a portion of the sorting solution; the sprayed sorting solution flows toward the bottom of the sorting drum 200, lifting up the gangue deposited at the bottom and accelerating the upward separation of the gangue.

[0046] Step 4: After continuous sorting for a predetermined time, control the sorting drum 200 to stop rotating or reciprocate, and use a negative pressure device to collect the sorted gold ore slurry remaining in multiple sorting areas 2101 within the sorting drum 200.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
