Description

Technical Field

[0001] The invention relates to the technical field of dam construction, in particular to tailings distribution dam construction equipment. Background Art

[0002] Tailings damming refers to the process of gradually building and raising the tailings dam by discharging, spreading and compacting the tailings slurry (mainly a mixture of granular tailings sand and water) produced by the mineral processing plant according to a set plan, sequence and location through a set of systematic methods and equipment.

[0003] The entire dam construction process can be summarized as: preparatory work, grading and discharge, sedimentation and drainage, paving and compaction, sub-dam construction and shaping, as well as inspection and maintenance. The grading and discharge process is as follows: first, the initial tailings slurry is introduced into the cyclone, and then the tailings slurry treated by the cyclone (mainly containing coarse-grained tailings sand and water, but some fine-grained tailings sand will still remain after cyclone treatment) is discharged to the top of the dam body through the pipe on the arm. After the tailings slurry falls on the dam body, the coarse particles remain on the dam body, forming a high-strength and permeable dam body, and the fine particles are washed far into the reservoir, forming an impermeable layer and weight in the reservoir, thus forming a natural particle grading, which is conducive to the stability of the dam body.

[0004] The above existing process has the following problems: although the tailings slurry is treated by the cyclone, it still contains some fine-grained tailings. Therefore, the dam body formed has poor permeability due to the large amount of fine-grained tailings inside, which affects the overall strength and stability of the dam body.

[0005] Secondly, in the current discharge process, discharge is usually carried out at a single fixed point. As a result, the tailings slurry continues to impact the same position for a long time, causing deep pits to form on the surface of the dam at the fixed discharge point, which ultimately affects the stability of the internal structure of the dam. In addition, discharge from the same fixed point can easily cause excessive accumulation of tailings sand at a certain location, affecting subsequent deposition, paving and compaction steps. Summary of the Invention

[0016] According to a favorable embodiment, the driving unit includes a transverse seat, and a transverse seat is set between the two supporting rods on the same side for sliding back and forth together. The transverse seat is penetrated by two mounting columns distributed front and back and with axes extending from left to right. The mounting columns are fixedly connected to the integrated frame.

[0017] According to a favorable embodiment, the driving unit also includes a repositioning group arranged on the integrated frame and used to change the left and right positions of the integrated frame. The repositioning group includes a plug-in frame. A plug-in frame located on the right side of the integrated frame is arranged between the front and rear integrated frames. The plug-in frame is provided with multiple receivers arranged front and back, and a transmitter is fixedly provided on the right end face of the right transverse seat.

[0018] According to an advantageous embodiment, the opposite surfaces of the front and rear integrated racks are provided with a plurality of plug-in slots equidistantly arranged from left to right, and plug-in blocks are provided at both the front and rear ends of the plug-in racks.

DETAILED DESCRIPTION

[0033] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0034] As Figure 1 and Figure 7As shown in the figure, a tailings damming device, used in cooperation with a mobile device, a cyclone, a stacked screen and three conveying arms, comprises: two integrated frames 1 symmetrically arranged in front and back on the mobile device, four supporting rods 2 arranged in a rectangular shape and with their axes extending from front to back fixedly arranged between the two integrated frames 1, and an integrated frame 3 slidably arranged on the four supporting rods 2 in front and back, wherein a discharging mechanism 4 is arranged on the integrated frame 3.

[0035] As shown in the figure, Figure 1 and Figure 2 The discharging mechanism 4 comprises a sliding block 40, and three sliding blocks 40 are arranged in the integrated frame 3, with the rightmost sliding block 40 fixedly connected to the integrated frame 3 and the remaining two sliding blocks 40 slidably arranged on the integrated frame 3, a feeding pipe 400 is arranged through the sliding block 40, and the feeding pipe 400 is connected to the stacked screen through a corresponding conveying arm.

[0036] The coarse particle tailings slurry, the medium particle tailings slurry and the fine particle tailings slurry processed by the cyclone and the stacked screen are sequentially conveyed from the rightmost feeding pipe 400, the middle feeding pipe 400 and the leftmost feeding pipe 400.

[0037] The sliding block 40 is provided with a flow dividing unit 41 for reducing the impact force generated when the tailings slurry is discharged, and the flow dividing unit 41 comprises a buffer bin 410 and two front and back arranged flow dividing pipes 411, the tailings slurry in the feeding pipe 400 enters the buffer bin 410 to reduce the impact for the first time, and is discharged through the two flow dividing pipes 411 to reduce the impact of the tailings slurry again.

[0038] The integrated frame 3 is provided with a drive group for adjusting the positions of the middle sliding block 40 and the left sliding block 40.

[0039] The two integrated frames 1 are provided with a drive unit 43, and the integrated frame 3 drives the three feeding pipes 400 to move from front to back through the drive unit 43, and the movement track is a broken line.

[0040] It should be noted that the cyclone, laminated screen and three conveying arms are all arranged on a mobile device (not shown in the figure), wherein the cyclone divides the preliminary tailings slurry into an overflow with fine particles and an underflow containing coarse particles by the principle of centrifugal sedimentation, i.e., performs preliminary processing operations, after which the slurry in the underflow enters the laminated screen, and the laminated screen performs fine screening based on the principle of high-frequency, low-amplitude vibration, and is processed again by the laminated screen. The cyclone and the laminated screen are used in conjunction to screen out tailings slurries of various particle sizes, and then the tailings slurries are transported to corresponding positions by the pipes in the conveying arms, and the integrated frame 1 is manually fixed after rotation, so that the integrated frame 1 is in an operating state, wherein the pipes in the three conveying arms are respectively connected to the corresponding conveying pipes 400, and during the operation, the corresponding tailings slurries after two treatments are transported to the corresponding conveying pipes 400. The above are all existing technologies and will not be elaborated here.

[0041] During operation, the mobile device drives the cyclone, the laminated screen, the three conveying arms and the integrated frame 1 to move to the set dam-building position, and then the integrated frame 1 is rotated so that the length direction of the integrated frame 1 extends from front to back. The pipes in the three conveying arms are respectively connected to the corresponding conveying pipes 400, and the conveying pipes 400 corresponding to the coarse particles are located at the dam top position of the dam-building position, thus completing the preparation work before dam-building.

[0042] Afterwards, the three types of tailings slurries (coarse-grained tailings slurry, medium-grained tailings slurry and fine-grained tailings slurry) processed by the cyclone and the laminated screen enter the corresponding feed pipe 400 respectively. It should be noted that the left and right positions of the feed pipe 400 corresponding to the middle slider 40 and the feed pipe 400 corresponding to the leftmost slider 40 are adjusted by the drive group, thereby adjusting the discharge position of the medium-grained tailings slurry and the fine-grained tailings slurry to meet the needs of the dam construction process. At the same time, the three types of tailings slurries are discharged in sequence so that the coarse particles accumulate close to the dam body to form a stable dam body, and the medium-grained tailings slurry and the fine-grained tailings slurry accumulate away from the dam body to form an impermeable layer and pressure weight. Separate feeding and dam construction helps to improve the stability of the dam body.

[0043] Secondly, it should be noted that during the unloading process, the tailings slurry in the corresponding feed pipe 400 first enters the buffer bin 410 through the diversion unit 41 and flows out through the corresponding front and rear diversion pipes 411, thereby reducing the impact force generated by the tailings slurry and avoiding excessive impact on the unformed dam body.

[0044] See Figure 6The driving unit 43 works so that the moving trajectory of the integrated frame 3 is in a broken line shape during the back-and-forth reciprocating movement. Therefore, the discharge trajectories of all the conveying pipes 400 and the diversion pipes 411 are all in a broken line shape. Through the above method, excessive impact caused by continuous discharge of materials at the same position is avoided, and at the same time, the tailings slurry is evenly distributed, avoiding excessive accumulation of tailings slurry in a certain area that affects the stability of the dam body and the dam construction process.

[0045] like Figure 1 、 Figure 2 and Figure 3 As shown, two mounting rods 412 are fixedly provided on the integrated frame 3 and are distributed front to back with axes extending from left to right. The slider 40 is sleeved on the two mounting rods 412 .

[0046] A buffer bin 410 is fixedly provided on the lower end surface of the slider 40 through a fixing frame, the feed pipe 400 is connected to the corresponding buffer bin 410, and a diversion pipe 411 connected to the buffer bin 410 is fixedly provided on the front and rear sides of the buffer bin 410, and a flaring sleeve 413 with a smaller upper portion and a larger lower portion is fixedly provided at the lower opening of the diversion pipe 411.

[0047] like Figure 3 As shown, a plurality of rotating rods 414 distributed from left to right and with axes extending forward and backward are rotatably arranged in the flaring sleeve 413 , and a triangular unloading block 415 is fixedly sleeved on the rotating rod 414 .

[0048] During operation, the tailings slurry enters the buffer bin 410 through the feed pipe 400 and fills the buffer bin 410, thereby reducing the impact force of the tailings slurry. The tailings slurry in the buffer bin 410 then flows out through the diversion pipes 411 on the front and rear sides respectively. The method of discharging through two diversion pipes 411 increases the discharge speed and reduces the impact force during discharge compared to the single-pipe discharge method. Secondly, the expansion sleeve 413 reduces the discharge speed of the tailings slurry by increasing the cross-sectional area at the discharge point, thereby reducing the impact of the tailings slurry on the dam body. When the tailings slurry is discharged from the expansion sleeve 413, it contacts the unloading block 415, causing the unloading block 415 to rotate. While the unloading block 415 rotates, it has a certain hindering effect on the discharge of the tailings slurry, thereby reducing the impact of the tailings slurry on the dam body after discharge.

[0049] In summary, the impact reduction through the transition of the buffer bin 410, the discharge method of the two diversion pipes 411, the shape characteristics of the expansion sleeve 413 and the unloading process of the unloading block 415 are combined and coordinated with each other to ultimately reduce the impact force during the discharge of the tailings slurry, avoid the formation of scour pits or caves due to the impact force, separation of coarse particles, and induction of local landslides or collapses, reduce the impact on the stability of the dam body, and at the same time reduce the problem of slurry splashing due to excessive impact.

[0050] like Figure 1 and Figure 2As shown, the drive group includes a threaded rod 420, and two threaded rods 420 distributed front to back and with axes extending from left to right are rotated together on the rightmost slider 40 and the integrated frame 3. The threaded rod 420 passes through the remaining two sliders 40, the rear threaded rod 420 is threadedly engaged with the middle slider 40, and the front threaded rod 420 is threadedly engaged with the left slider 40. The threaded rod 420 is connected to an external motor (not shown in the figure).

[0051] During operation, the external motor drives the threaded rod 420 to rotate. The threaded rod 420 cooperates with the thread of the corresponding slider 40, so that the slider 40 drives the feed pipe 400 thereon to move left and right synchronously, thereby adjusting the left and right positions of the middle slider 40 and the left slider 40, that is, adjusting the discharge position of medium particles and fine particles to meet different tailings slurry discharge requirements.

[0052] Secondly, it should be noted that by discharging the coarse-grained tailings slurry, the medium-grained tailings slurry and the fine-grained tailings slurry separately to the set area, the coarse-grained tailings slurry is discharged close to the dam body, and the medium-grained tailings slurry and the fine-grained tailings slurry are kept away from the dam body according to the corresponding degree of particle size. The coarse particles form a dam body with strong permeability and high shear strength, while the medium and fine particles have poor permeability, forming a natural impermeable layer and providing support and weight for the dam body, thereby forming an impermeable, weighted and environmentally friendly core, improving the stability of the dam body, and by rotating the threaded rod 420, the medium and fine particles are adjusted in the process of dam construction, ensuring that the discharge position meets the dam construction requirements in a more refined manner.

[0053] like Figure 1 and Figure 2 As shown, the driving unit 43 includes a transverse seat 430, and a transverse seat 430 is provided between the two supporting rods 2 on the same side for sliding back and forth. Two mounting columns 431 distributed front and back and with axes extending from left to right are passed through the transverse seat 430 for sliding left and right. The mounting columns 431 are fixedly connected to the integrated frame 3, and a hydraulic push rod (not shown in the figure) is fixedly provided between the transverse seat 430 and the integrated frame 3. An external hydraulic cylinder (not shown in the figure) for driving the transverse seat 430 to move back and forth is provided between the transverse seat 430 and the front integrated frame 1.

[0054] like Figure 1 and Figure 4 As shown, the driving unit 43 also includes a repositioning group arranged on the integrated frame 1 and used to change the left and right positions of the integrated frame 3. The repositioning group includes a plug-in rack 432. A plug-in rack 432 located on the right side of the integrated frame 3 is arranged between the front and rear integrated frames 1. A plurality of receivers 433 arranged front to back are arranged on the plug-in rack 432, and a transmitter 434 is fixedly provided on the right end face of the right transverse displacement seat 430.

[0055] During the forward and backward movement of the transverse seat 430, the transmitter 434 cooperates with the receiver 433 in sequence to control the extension and retraction of the hydraulic push rod, so that the integrated frame 3 moves back and forth, changing the discharge point of the diverter pipe 411 to form a broken line discharge trajectory. Figure 6 .

[0056] During the process of unloading and damming, the transverse seat 430 moves backward from its initial position close to the integrated frame 1. During the backward movement, the transverse seat 430 drives the transmitter 434 thereon to face the first receiver 433. The signal emitted by the transmitter 434 is received by the receiver 433 and transmitted to the control circuit. The control circuit controls the hydraulic push rod to operate, so that the integrated frame 3 moves to the left. The transverse seat 430 continues to move, and the transmitter 434 faces the second receiver 433 from front to back. The above signal receiving process is repeated. The control circuit controls the hydraulic push rod to operate, so that the integrated frame 3 moves to the right. Therefore, in the process of the transverse seat 430 moving back and forth, the moving trajectory of the integrated frame 3 is a broken line. Therefore, the moving trajectories of all the feed pipes 400 and the diversion pipes 411 are all broken lines.

[0057] The above-mentioned discharge method avoids the problem of excessive impact on the same position and the formation of deep pits caused by the fixed-point discharge method, and also avoids the problem of the internal structure of the dam body being damaged by the pit and affecting the stability. Secondly, the tailings slurry after discharge is evenly accumulated, avoiding the problem of excessive accumulation at a certain position caused by the fixed-point discharge method, thereby promoting uniform deposition and optimizing the dam body structure. In summary, the above-mentioned method improves the stability of the dam body. The coordination process between the above-mentioned receiver 433, transmitter 434, control circuit and hydraulic push rod is all existing technology and will not be elaborated on here.

[0058] like Figure 4 As shown, the opposite surfaces of the front and rear integrated racks 1 are provided with a plurality of plug-in slots 435 equidistantly arranged from left to right, and the front and rear ends of the plug-in rack 432 are provided with plug-in blocks 436 .

[0059] By inserting the plug-in blocks 436 on the plug-in frame 432 into different plug-in slots 435, the spacing between the plug-in frame 432 and the adjacent transverse shifting seat 430 is adjusted. The distance between the hydraulic push rods pushing the integrated frame 3 left and right is set to the desired value based on these different spacings. It should be noted that the receiver 433 receives the signal transmitted by the transmitter 434 to determine the spacing between the two. The control circuit controls the displacement of the hydraulic push rods based on the different spacings, thereby controlling the left and right movement distance of the integrated frame 3 and ultimately the lateral movement distance of the feed pipe 400. This expands the area for material transfer and unloading, ensures uniform material distribution, and promotes uniform deposition.

[0060] like Figure 4 and Figure 5As shown, the upper and lower end surfaces of the integrated frame 1 on the front side are provided with moving rods 440 with vertical axes that slide up and down through L-shaped frames, and the opposite surfaces of the two moving rods 440 are fixedly provided with U-shaped baffles 441, and the baffles 441 are fixedly provided with plug-in rods 442 for passing through adjacent supporting rods 2. The moving rods 440 are driven by external cylinders to move up and down.

[0061] The rear end surface of the front integrated frame 1 and the two baffles 441 after closing are used as two track references to form two mutually intersecting broken line feeding tracks, see Figure 6 .

[0062] like Figure 4 and Figure 6 As shown, a movable plate 443 is provided on the plug-in rack 432 for sliding back and forth, and all receivers 433 are fixedly provided on the left end face of the movable plate 443 . A reference plate 444 that cooperates with the integrated rack 1 and the baffle 441 is fixedly provided on the movable plate 443 .

[0063] The reference plate 444 contacts the rear end face of the front integrated frame 1, executing the first unloading trajectory. The reference plate 444 contacts the two closed baffles 441, executing the second unloading trajectory. The movable plate 443 is driven by an external electric push rod (not shown in the figure) to move back and forth.

[0064] Initially, the two baffles 441 are located on the side where the upper and lower supporting rods 2 are away from each other. At this time, the reference plate 444 contacts the rear end face of the integrated frame 1 and the unloading operation begins. At this time, the forward and backward movement trajectory of the integrated frame 3 is the first fold line unloading trajectory. After repeating the above unloading process many times, the external cylinder works to make the moving rod 440 drive the baffle 441 to move, and the two baffles 441 approach each other and make the plug-in rod 442 pass through the supporting rod 2. Finally, the two baffles 441 form the reference of the second unloading trajectory. After that, the moving plate 443 drives the receiver 433 and the reference plate 444 thereon to move backward. When the external electric push rod works to make the moving plate 443 drive the reference plate 444 to move, so that the reference plate 444 contacts the baffle 441, the second unloading process is entered. After repeating the above unloading process, the second fold line unloading trajectory is formed, and the wave peaks of the two fold line unloading trajectories are staggered, which increases the coverage area of ​​the unloading area, improves the distribution uniformity of the tailings slurry after unloading, promotes uniform deposition, and avoids the problem of excessive local accumulation.

[0065] It should be noted that before the operation, the receiver 433 is manually fixed to the movable plate 443, and the distance between two adjacent receivers 433 is adjusted to meet the requirements of the forward and backward movement of the integrated frame 3. The above distances are obtained through multiple experiments by existing technicians and are existing technologies, so there is no need to elaborate on them.

[0066] Compared with the direct discharge mode in the prior art, the broken line moving track of the integrated frame 3 is adopted to avoid continuous discharge at the same position and impact on the dam surface, thereby affecting the stability of the dam, and the impact force on the dam is further reduced by the flow distribution unit 41; compared with the prior art, the discharge mechanism 4 and the flow distribution unit 41 are added, and the cost is increased, but the discharge mechanism 4 and the flow distribution unit 41 are common mechanical components and can be used for multiple times, and the increase of the equipment cost of the structure of the application compared with the prior art can be completely ignored in the long-term economic benefits.
