Description

Technical Field

[0001] The utility model relates to the field of ore dressing equipment, in particular to an ore discharging structure of a suspended vibration cone ore dressing machine. Background Art

[0002] Tantalum and niobium minerals in most tantalum-niobium deposits in my country are embedded in a relatively fine particle size, requiring fine grinding to separate the individual minerals. Gravity separation is generally used as the primary recovery method for tantalum and niobium minerals, with tantalum and niobium being recovered comprehensively based on their different specific gravities. The suspended vibrating cone concentrator is an important piece of ore gravity separation equipment. When the uniformly stirred slurry enters the primary separation zone of the conical disc from the feeder at the center of the conical disc, the slurry flows in a fan-shaped pattern, gradually thinning the film and decreasing the flow rate. The ore particles are moderately loosened and stratified on the disc due to their own gravity and the shear repulsion generated by the gyratory vibration. The rotation of the conical disc sequentially draws minerals of varying densities into corresponding slots, effectively separating the minerals.

[0003] Cone concentrators offer the following advantages: 1) High processing capacity. Per square meter of floor space, the production capacity can range from hundreds of kilograms to several tons. For example, a 2.5-ton four-stage cone concentrator can process 60-75 tons / hour, making it suitable for processing large quantities of low-grade ore. 2) High feed concentration, resulting in relatively low water consumption. 3) Low operating costs, requiring no power or reagents. 4) Low enrichment ratios for a single concentrator, making it difficult to produce a final concentrate. 5) A wide particle size range, from 3 to 0.1 mm, is available, but recovery of fine particles is poor. Existing cone concentrators rely on the impact force of slow water flow to discharge the concentrate. Without an external driving force, discharge efficiency is very slow. This inability to quickly and efficiently discharge the concentrate complicates the discharge of newly generated concentrate, increasing overall resistance and reducing concentrate production efficiency. Utility Model Content

[0004] In response to the shortcomings of the above-mentioned existing cone-shaped mineral processing machines, such as the lack of external driving force, very slow ore discharge efficiency, and low output efficiency, the applicant provides a rationally structured suspended vibration cone-shaped mineral processing machine discharge structure that can discharge concentrate in a timely manner, accelerate the discharge of concentrate, and improve ore discharge efficiency.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A suspended cone concentrator discharge structure has a sorting disc, with a washing water pipe suspended above the sorting disc, the washing water pipe is arranged in a C-shaped gradient line, a concentrate flushing pipe is correspondingly provided in front of the cut-off end of the washing water pipe, and a discharge mechanism is provided on the concentrate flushing pipe. The main body of the discharge mechanism includes a short rod part, a long rod part, and a connecting part, the connecting part respectively connects one end of the short rod part and one end of the long rod part, the short rod part and the long rod part form an angle with each other, a spring is provided at the top of the connecting part, the upper end of the spring is fixedly installed on the bottom of the outer wall of the concentrate flushing pipe, and a plurality of downwardly drooping curtains are provided on the outer walls of the short rod part and the long rod part.

[0007] As a further improvement of the above technical solution:

[0008] The sorting disc surface is composed of an inner conical surface and an outer conical surface. The inner conical surface is located in the center of the outer conical surface. A hemispherical cover is provided above the center of the inner conical surface. A feeding device is suspended above the top of the hemispherical cover.

[0010] One end of the washing water pipe extends from the outside of the sorting disk to the center of the sorting disk along the diameter direction of the sorting disk, and then bends into a C shape, gradually increasing the distance from the center of the sorting disk during the extension.

[0011] The cut-off end of the washing water pipe is closed, and a plurality of openings facing the sorting disc surface are opened on the pipe of the gradient line part of the washing water pipe.

[0012] The concentrate flushing pipe adopts a Y-shaped pipeline structure, including a first section of pipeline and a second section of pipeline.

[0016] The vertical curtain is formed by a row of multiple independent rubber sheets.

[0017] The beneficial effects of the utility model are as follows:

[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] The present invention is described more fully below with reference to the accompanying drawings, which illustrate various aspects of the present invention. The present invention may be implemented in various forms and should not be construed as limited to the various aspects of the present invention presented in this implementation section. Unless otherwise defined, all terms used herein (including industry terms) have the same meanings as commonly understood by persons of ordinary skill in the art to which the present invention pertains.

[0025] Various aspects of the present invention will be described below with reference to the accompanying drawings, which are schematic illustrations of idealized configurations of the present invention. As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0026] Reference Figures 1 to 3 As shown, the ore discharging structure of the suspended cone concentrator described in the present invention comprises a sorting disc 1, which is composed of an inner conical surface 2 and an outer conical surface 3 connected together. The inner conical surface 2 is located at the center of the outer conical surface 3, and the outer conical surface 3 is arranged circumferentially around the inner conical surface 2. The inner conical surface 2 and the outer conical surface 3 are smoothly connected to form a whole. A hemispherical cover 4 is provided above the center of the inner conical surface 2, and the hemispherical cover 4 covers the inner conical surface 2. The inner conical surface 2, the outer conical surface 3, and the hemispherical cover 4 are arranged concentrically. A feed device 5 is suspended above the top of the hemispherical cover 4, extending from the outside to the top of the hemispherical cover 4. The external ore slurry flows through the feed device 5 to the top of the hemispherical cover 4, diffuses along the hemispherical cover 4, and flows to the inner conical surface 2 and the outer conical surface 3.

[0027] Below the sorting disc 1 is the sub-table structure of the cone concentrator, which houses a vibration mechanism and a rotary drive mechanism. The vibration mechanism primarily comprises a vibration motor, located on the bottom back of the sorting disc 1, and is used to drive the sorting disc 1 to vibrate. The rotary drive mechanism primarily comprises a rotary drive motor, which is used to support and drive the sorting disc 1 to rotate.

[0028] During the rotation of the sorting disc 1, when the evenly stirred slurry flows from the center of the cone to the inner cone 2 and the outer cone 3, the slurry flow spreads out in a fan shape and flows toward the periphery. During the flow, the flow film gradually becomes thinner and the flow rate gradually decreases, thereby gravity sorting the concentrate, middlings and tailings.

[0029] A sorting trough 6 is arranged around the outer circumference of the sorting disc 1. The sorting trough 6 includes a tailings trough 7, a middling trough 8, and a concentrate trough 9. The tailings trough 7, the middling trough 8, and the concentrate trough 9 together form the sorting trough 6. The tailings trough 7 collects the tailings flowing down from the sorting disc 1, the middling trough 8 collects the middlings flowing down from the sorting disc 1, and the concentrate trough 9 collects the concentrate flowing down from the sorting disc 1.

[0030] A washing water pipe 10 is suspended above the sorting disk 1. The washing water pipe 10 is arranged in a C-shaped gradient line. One end of the washing water pipe 10 extends from the outside of the sorting disk 1 to the center of the sorting disk 1 along the diameter direction of the sorting disk 1, and then bends into a C shape. The distance from the center of the sorting disk 1 gradually increases during the extension, and finally forms a gradient line structure.

[0031] The end of the washing water pipe 10 is sealed. Several openings facing the sorting disc 1 are provided in the gradient portion of the pipe. Washing water is injected into the slurry on the sorting disc 1 through these openings. As water is injected into the gradient portion of the pipe 10, the tailings move to the corresponding position of the tailings trough 7 and are collected there. The middlings move to the corresponding position of the middling trough 8 and are collected there. The washing water pipe 10 is supplied with running water from an external water source and can be secured using a gantry bracket structure.

[0032] A concentrate flushing pipe 11 is provided in front of the cut-off end of the washing water pipe 10. The concentrate flushing pipe 11 adopts a Y-shaped pipe structure, including a first section of pipe and a second section of pipe. The first section of pipe is a main pipe, which extends from the outside to a distance on the sorting disk 1. The second section of pipe is inclined on the first section of pipe and is interconnected with the first section of pipe. A flushing nozzle 12 is provided at the end of the second section of pipe. The flowing water in the concentrate flushing pipe 11 is sprayed to the slurry on the sorting disk 1 through the flushing nozzle 12, so that the concentrate moved here is discharged from the sorting disk 1 and reaches the concentrate trough 9.

[0033] A discharge mechanism 13 is provided on the first section of the concentrate flushing pipe 11. The main body of the discharge mechanism 13 includes a short rod portion 14, a long rod portion 15, and a connecting portion 16. The connecting portion 16 connects one end of the short rod portion 14 and one end of the long rod portion 15, respectively. The short rod portion 14 and the long rod portion 15 are located on both sides of the connecting portion 16. The short rod portion 14 and the long rod portion 15 form an angle with each other and are not on the same horizontal line. The length ratio of the short rod portion 14 to the long rod portion 15 is approximately 3:7. A spring 17 is provided on the top of the connecting portion 16. The lower end of the spring 17 is connected to the connecting portion 16, and the upper end is fixedly mounted on the bottom of the outer wall of the first section of the concentrate flushing pipe 11.

[0034] When the ore discharge mechanism 13 shakes, the spring 17 can shake along with the shaking of the short rod 14, the long rod 15, and the connecting portion 16. A plurality of downwardly hanging curtains 18 are provided on the outer walls of the short rod 14 and the long rod 15. The curtains 18 are preferably formed of a row of independent rubber sheets.

[0035] Due to the vibration of the sorting disc 1 itself, the discharge mechanism 13 will vibrate. Due to the flow of water injected from the concentrate flushing pipe 11, a lateral driving force will be generated on the curtain 18 of the discharge mechanism 13, causing the discharge mechanism 13 to shake to a certain extent. Since the length ratio of the short rod 14 and the long rod 15 is approximately 3:7, the imbalance between the short rod 14 and the long rod 15 will increase, causing the shaking of the discharge mechanism 13 to intensify. During the shaking process of the discharge mechanism 13, the concentrate moving here will be swept, so that the concentrate concentrated here will be discharged into the corresponding concentrate trough 9 at an accelerated speed, thereby improving the output effect of the concentrate.

[0036] During the implementation of the present invention, when the machine is turned on, the external slurry flows to the top of the hemispherical cover 4 through the feeding device 5, and diffuses to the surroundings along the hemispherical cover 4 and flows to the inner conical surface 2 and the outer conical surface 3. The vibration mechanism and the rotary drive mechanism below the sorting disc 1 drive the sorting disc 1 to vibrate and rotate. During the rotation of the sorting disc 1, when the evenly stirred slurry flows from the center of the cone to the inner conical surface 2 and the outer conical surface 3, the slurry flow spreads out in a fan shape and flows to the periphery. During the flow process, the flow film gradually becomes thinner from thick, and the flow rate gradually decreases, thereby gravity sorting the concentrate, middlings and tailings.

[0037] A concentrate flushing pipe 11 is provided on the sorting disc 1, and a discharge mechanism 13 is provided on the first section of the concentrate flushing pipe 11. Due to the vibration of the sorting disc 1 itself, the discharge mechanism 13 will vibrate. Due to the flow of water injected from the concentrate flushing pipe 11, a lateral driving force will be generated on the vertical curtain 18 of the discharge mechanism 13, causing the discharge mechanism 13 to shake to a certain extent. Since the length ratio of the short rod 14 and the long rod 15 is approximately 3:7, the imbalance between the short rod 14 and the long rod 15 will increase, resulting in the intensification of the shaking of the discharge mechanism 13. During the shaking process of the discharge mechanism 13, the concentrate moving here will be swept, so that the concentrate concentrated here will be discharged into the corresponding concentrate trough 9 at an accelerated speed, thereby improving the output effect of the concentrate.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
