Abstract
Description
Technical Field
[0001] This invention relates to the field of dam construction technology, specifically to a tailings material placement dam construction device. Background Technology
[0002] Tailings dam construction refers to the process of gradually constructing and elevating a tailings dam by discharging, spreading, and compacting tailings slurry (mainly composed of granular tailings sand and water) generated by a mineral processing plant according to a set plan, sequence, and location using a systematic method and equipment.
[0003] The entire dam construction process can be summarized as follows: preparation work, classification and discharge, sedimentation and drainage, spreading and compaction, construction and shaping of sub-dams, and inspection and maintenance. The classification and discharge process is as follows: First, the initial tailings slurry is introduced into a hydrocyclone. Then, the tailings slurry (mainly containing coarse tailings sand and water, but some fine tailings sand will still remain after hydrocyclone treatment) is discharged to the top of the dam body through the pipe on the boom. After the tailings slurry falls onto the dam body, the coarse particles remain on the dam body, forming a high-strength and permeable dam body, while the fine particles are washed far into the reservoir, forming an impermeable layer and ballast in the reservoir. Thus, natural particle classification is formed, which is conducive to the stability of the dam body.
[0004] The existing process described above has the following problems: Although the tailings slurry is treated by a hydrocyclone, it still contains some fine-grained tailings. As a result, the dam body formed has poor permeability due to the presence of a large amount of fine-grained tailings, which affects the overall strength and stability of the dam body.
[0005] Secondly, the current discharge process usually involves discharge at a single fixed point. As a result, the continuous impact of tailings slurry on the same location over a long period of time causes deep pits to form on the surface of the dam at that fixed discharge point. This ultimately affects the stability of the internal structure of the dam. Furthermore, discharge at the same fixed point can easily lead to excessive accumulation of tailings sand at a certain location, affecting subsequent steps such as sedimentation, spreading, and compaction. Summary of the Invention
[0006] Therefore, it is necessary to provide a tailings damming equipment to solve the problems of the aforementioned existing technology.
[0007] This application provides a tailings dam-building device, which is used in conjunction with a mobile device, a hydrocyclone, a stacked screen, and three conveying booms. The device includes: two integrated frames that are rotatably mounted on the mobile device and symmetrically distributed front and back; four rectangular support rods with their axes extending from front to back are fixedly mounted between the two integrated frames; an integrated frame is slidably mounted on the four support rods; and a feeding mechanism is mounted on the integrated frame.
[0008] The feeding mechanism includes sliders. Three sliders are arranged in the integrated frame, distributed left and right. The rightmost slider is fixedly connected to the integrated frame, and the remaining two sliders are slidably arranged on the integrated frame. A feeding pipe is provided through the slider.
[0009] The slider is equipped with a diversion unit to reduce the impact force generated when the tailings slurry is discharged. The diversion unit includes a buffer chamber and two diversion pipes distributed front and back. The tailings slurry in the conveying pipe enters the buffer chamber to reduce some of the impact for the first time, and the tailings slurry impact is further reduced when it is discharged through the two diversion pipes.
[0010] The integrated frame is equipped with a drive group for adjusting the positions of the middle slider and the left slider.
[0011] A drive unit is provided between the two integrated frames. The drive unit enables the integrated frame to move the three material conveying pipes from front to back in a zigzag pattern.
[0012] According to an advantageous embodiment, two mounting rods are fixedly disposed on the integrated frame, distributed front to back and extending from left to right, and a slider is sleeved on the two mounting rods.
[0013] The lower end face of the slider is fixedly provided with a buffer chamber by a fixing frame. The feed pipe is connected to the corresponding buffer chamber. Both the front and rear sides of the buffer chamber are fixedly provided with a diversion pipe connected to the buffer chamber. The lower opening of the diversion pipe is fixedly provided with a flared sleeve that is smaller at the top and larger at the bottom.
[0014] According to an advantageous embodiment, the flared sleeve is rotatably provided with a plurality of rotating rods distributed from left to right and extending front to back along their axes, and triangular stress relief blocks are fixedly sleeved on the rotating rods.
[0015] According to an advantageous embodiment, the drive assembly includes threaded rods, and two threaded rods distributed front to back and extending from left to right are rotatably disposed on the rightmost slider and the integrated frame. The threaded rods pass through the remaining two sliders, with the rear threaded rod threadedly engaged with the middle slider and the front threaded rod threadedly engaged with the left slider.
[0016] According to an advantageous embodiment, the drive unit includes a transverse sliding seat, on which two support rods on the same side are slidably arranged back and forth. The transverse sliding seat has two mounting columns that are distributed back and forth and whose axes extend from left to right through it. The mounting columns are fixedly connected to the integrated frame.
[0017] According to an advantageous embodiment, the drive unit further includes a repositioning group disposed on the integration frame and used to change the left and right position of the integration frame. The repositioning group includes a plug-in frame, and a plug-in frame located on the right side of the integration frame is disposed between the front and rear integration frames. A plurality of receivers arranged in a front and rear arrangement are disposed on the plug-in frame, and a transmitter is fixedly disposed on the right end face of the right side transverse seat.
[0018] According to an advantageous embodiment, the opposite surfaces of the two integrated frames are provided with a plurality of insertion slots arranged equidistantly from left to right, and insertion blocks are provided at both the front and rear ends of the insertion frame.
[0019] According to an advantageous embodiment, both the upper and lower end faces of the front integrated frame are provided with vertically oriented moving rods via L-shaped frames, and U-shaped baffles are fixedly provided on the opposite faces of the two moving rods. Insertion rods for penetrating adjacent support rods are fixedly provided on the baffles.
[0020] According to an advantageous embodiment, a movable plate is slidably disposed on the plug-in frame, and all receivers are fixedly disposed on the left end face of the movable plate. A reference plate that cooperates with the integrated frame and the baffle is fixedly disposed on the movable plate.
[0021] When the reference plate contacts the rear end face of the integrated frame, the first feeding trajectory is executed. When the reference plate contacts the two baffles after they are closed, the second feeding trajectory is executed.
[0022] In summary, the present invention has at least one of the following beneficial effects: The present invention processes tailings slurry by using a stacked screen and a hydrocyclone in combination to form coarse tailings slurry, medium tailings slurry and fine tailings slurry. The three types of tailings slurry are discharged in sequence so that the coarse particles accumulate close to the dam body to form a stable dam body, while the medium and fine tailings slurries accumulate away from the dam body to form a seepage barrier and ballast. The method of separate material conveying for dam construction helps to improve the stability of the dam body.
[0023] During the process of transporting tailings slurry to the dam surface, the impact force of the tailings slurry is reduced twice by the diversion unit. The drive unit makes the integrated frame move in a zigzag pattern during the back-and-forth movement. Therefore, the discharge trajectory of all conveying pipes and diversion pipes is zigzag, which avoids continuous impact on the same fixed point and prevents the tailings slurry from excessively impacting the dam surface and forming impact pits that affect the stability of the dam. At the same time, it makes the tailings slurry evenly distributed and promotes sedimentation. Attached Figure Description

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0034] like Figure 1 and Figure 7As shown, a tailings dam-building device is used in conjunction with a mobile device, a hydrocyclone, a stacked screen, and three conveying booms. It includes: two integrated frames 1 that are rotatably mounted on the mobile device and symmetrically distributed front and back; four rectangular support rods 2 that are fixedly arranged between the two integrated frames 1 and whose axes extend from front to back; an integrated frame 3 that is slidably mounted on the four support rods 2; and a feeding mechanism 4 that is mounted on the integrated frame 3.
[0035] like Figure 1 and Figure 2 As shown, the feeding mechanism 4 includes sliders 40. Three sliders 40 are arranged in the integrated frame 3, distributed left and right. The rightmost slider 40 is fixedly connected to the integrated frame 3, and the remaining two sliders 40 are slidably arranged on the integrated frame 3. A conveying pipe 400 is provided through the slider 40, and the conveying pipe 400 is connected to the stacked screen through the corresponding conveying arm.
[0036] The coarse tailings slurry, medium tailings slurry, and fine tailings slurry, after being processed by hydrocyclones and stacked screens, are conveyed sequentially from the rightmost conveying pipe 400, the middle conveying pipe 400, and the leftmost conveying pipe 400, respectively.
[0037] The slider 40 is equipped with a diversion unit 41 for reducing the impact force generated when the tailings slurry is discharged. The diversion unit 41 includes a buffer chamber 410 and two diversion pipes 411 distributed front and back. The tailings slurry in the conveying pipe 400 enters the buffer chamber 410 to reduce part of the impact for the first time, and the tailings slurry impact is further reduced when it is discharged through the two diversion pipes 411.
[0038] The integrated frame 3 is provided with a drive group for adjusting the position of the middle slider 40 and the left slider 40.
[0039] A drive unit 43 is provided between the two integrated frames 1. The drive unit 43 enables the integrated frame 3 to drive the three material conveying pipes 400 to move from front to back, and the movement trajectory is a zigzag shape.
[0040] It should be further explained that the hydrocyclone, stacked screen, and three conveyor booms are all mounted on the mobile equipment (not shown in the figure). The hydrocyclone uses the principle of centrifugal sedimentation to separate the initial tailings slurry into an overflow with fine particles and an underflow containing coarse particles, which is the initial treatment operation. Then, the slurry in the underflow enters the stacked screen, which performs fine screening based on the principle of high frequency and low amplitude vibration. The tailings slurry is processed again by the stacked screen. By using the hydrocyclone and the stacked screen in combination, tailings slurry with different particle sizes is screened out. Then, the tailings slurry is transported to the corresponding positions by the pipes in the conveyor booms. After the integrated frame 1 rotates, it is manually fixed to make the integrated frame 1 in the working state. The pipes in the three conveyor booms are respectively connected to the corresponding conveying pipes 400, and during the operation, the corresponding tailings slurry after two treatments is transported to the corresponding conveying pipes 400. The above are all existing technologies and will not be described in detail here.
[0041] During operation, the mobile device moves the hydrocyclone, stacked screen, three conveying arms and integrated frame 1 to the dam construction setting position. Then, the integrated frame 1 is rotated to face the direction so that the length of the integrated frame 1 extends from front to back. The pipes in the three conveying arms are respectively connected to the corresponding material conveying pipes 400, and the material conveying pipe 400 corresponding to the coarse particles is located at the top of the dam construction position. This completes the preparatory work before dam construction.
[0042] After being processed by hydrocyclones and stacked screens, the three types of tailings slurries (coarse-grained tailings slurry, medium-grained tailings slurry, and fine-grained tailings slurry) enter their respective conveying pipes 400. It should be noted that by adjusting the left and right positions of the conveying pipes 400 corresponding to the middle slider 40 and the leftmost slider 40, the discharge positions of the medium-grained and fine-grained tailings slurries can be adjusted to meet the needs of the dam construction process. At the same time, the sequential discharge of the three types of tailings slurries allows the coarse particles to accumulate close to the dam body to form a stable dam body, while the medium-grained and fine-grained tailings slurries accumulate away from the dam body to form a seepage prevention layer and ballast. Separate conveying and dam construction helps to improve the stability of the dam body.
[0043] Secondly, it should be noted that during the feeding process, the tailings slurry in the corresponding conveying pipe 400 is first fed into the buffer bin 410 by the diversion unit 41 and then flows out through the corresponding diversion pipes 411 before and after, thereby reducing the impact force generated by the tailings slurry and avoiding excessive impact on the unformed dam body.
[0044] See Figure 6The operation of the drive unit 43 causes the integrated frame 3 to move in a zigzag pattern during its reciprocating motion. Therefore, the discharge trajectories of all conveying pipes 400 and diversion pipes 411 are zigzag. This avoids excessive impact caused by continuous discharge at the same location and ensures uniform distribution of tailings slurry, preventing excessive accumulation of tailings slurry in a certain area from affecting the stability of the dam and the dam construction process.
[0045] like Figure 1 , Figure 2 and Figure 3 As shown, two mounting rods 412 are fixedly arranged on the integrated frame 3, which are distributed front to back and whose axes extend from left to right. The slider 40 is sleeved on the two mounting rods 412.
[0046] The lower end face of the slider 40 is fixedly provided with a buffer chamber 410 by a fixing frame. The feed pipe 400 is connected to the corresponding buffer chamber 410. Both the front and rear sides of the buffer chamber 410 are fixedly provided with a diversion pipe 411 connected to the buffer chamber 410. The lower opening of the diversion pipe 411 is fixedly provided with a flared sleeve 413 that is smaller at the top and larger at the bottom.
[0047] like Figure 3 As shown, a plurality of rotating rods 414 are rotatably arranged inside the flared sleeve 413, distributed from left to right and extending front to back along their axes. Triangular stress relief blocks 415 are fixedly sleeved on the rotating rods 414.
[0048] During operation, the tailings slurry enters the buffer chamber 410 through the conveying pipe 400 and fills the buffer chamber 410, thereby reducing the impact force of the tailings slurry. Then, the tailings slurry in the buffer chamber 410 flows out through the front and rear diversion pipes 411. Compared with the single-pipe discharge method, the discharge method through two diversion pipes 411 increases the discharge speed and reduces the impact force during discharge. Secondly, the flared sleeve 413 increases the cross-sectional area of the discharge point to reduce the discharge speed of the tailings slurry and reduce the impact of the tailings slurry on the dam body. When the tailings slurry is discharged from the flared sleeve 413, it comes into contact with the unloading block 415, causing the unloading block 415 to rotate. The rotation of the unloading block 415 has a certain obstruction effect on the discharge of the tailings slurry, reducing the impact of the tailings slurry on the dam body after discharge.
[0049] In summary, by combining the impact reduction of the buffer chamber 410, the discharge method of the two diversion pipes 411, the shape characteristics of the flared sleeve 413, and the unloading process of the unloading block 415, the impact force of tailings slurry discharge is reduced, thus avoiding problems such as scouring pits or caves, coarse particle separation, and inducing local landslides or collapses caused by impact force. This reduces the impact on the stability of the dam and also reduces the problem of slurry splashing caused by excessive impact.
[0050] like Figure 1 and Figure 2As shown, the drive assembly includes threaded rods 420. Two threaded rods 420 are rotatably arranged on the rightmost slider 40 and the integrated frame 3, with their axes extending from left to right. The threaded rods 420 pass 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 rods 420 are 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, through the threaded engagement with its corresponding slider 40, causes the slider 40 to drive the conveying pipe 400 on it to move left and right synchronously. This adjusts the left and right positions of the middle slider 40 and the left slider 40, that is, adjusts the feeding position of medium and fine particles, which is suitable for different tailings slurry discharge requirements.
[0052] Secondly, it should be added that by separately discharging the coarse, medium, and fine tailings slurries to designated areas, the coarse particles are placed close to the dam body, while the medium and fine particles are placed further away from the dam body according to their particle size. The coarse particles form a dam body with high permeability and shear strength, while the medium and fine particles, with their poor permeability, form a natural seepage barrier and provide supporting weight for the dam body. This creates a seepage-proof, weight-bearing, and environmentally friendly core, improving the stability of the dam body. Furthermore, by rotating the threaded rod 420 degrees during the dam construction process, the placement of the medium and fine particles can be adjusted more precisely to ensure that the placement meets the dam construction requirements.
[0053] like Figure 1 and Figure 2 As shown, the drive unit 43 includes a transverse sliding seat 430. The transverse sliding seat 430 is slidably disposed between two support rods 2 on the same side. Two mounting columns 431, which are distributed front to back and extend from left to right, slide through the transverse sliding seat 430. The mounting columns 431 are fixedly connected to the integrated frame 3. A hydraulic push rod (not shown in the figure) is fixedly disposed between the transverse sliding seat 430 and the integrated frame 3. An external hydraulic cylinder (not shown in the figure) is disposed between the transverse sliding seat 430 and the front integrated frame 1 for driving the transverse sliding seat 430 to move back and forth.
[0054] like Figure 1 and Figure 4 As shown, the drive unit 43 also includes a repositioning group disposed on the integrated frame 1 and used to change the left and right position of the integrated frame 3. The repositioning group includes a plug-in frame 432. A plug-in frame 432 located on the right side of the integrated frame 3 is disposed between the front and rear integrated frames 1. A plurality of receivers 433 arranged in the front and rear are disposed on the plug-in frame 432. A transmitter 434 is fixedly disposed on the right end face of the right side transverse seat 430.
[0055] During the forward and backward movement of the transverse shifter 430, the transmitter 434 and receiver 433 work together to control the extension and retraction of the hydraulic push rod, causing the integrated frame 3 to move left and right reciprocally, changing the feeding point of the diversion pipe 411 and forming a zigzag feeding trajectory. (See reference...) Figure 6 .
[0056] During the material feeding and dam construction process, the transverse shift seat 430 moves backward from its initial position close to the integrated frame 1. During this backward movement, the transverse shift seat 430 drives the transmitter 434 on it 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 work, thereby causing the integrated frame 3 to move to the left. The transverse shift 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 work, causing the integrated frame 3 to move to the right. Thus, during the back-and-forth movement of the transverse shift seat 430, the movement trajectory of the integrated frame 3 is a zigzag shape. Therefore, the movement trajectories of all material conveying pipes 400 and diversion pipes 411 are also zigzag shapes.
[0057] The above-described discharge method avoids the problem of excessive impact on the same location and the formation of deep pits caused by fixed-point discharge, and also avoids the problem of pitting damaging the internal structure of the dam and affecting its stability. Secondly, it ensures that the tailings slurry is evenly deposited after discharge, avoiding the problem of excessive accumulation in one location caused by fixed-point discharge, thereby promoting uniform sedimentation and optimizing the dam structure. In summary, the above methods improve the stability of the dam. The cooperation process between the receiver 433, transmitter 434, control circuit, and hydraulic push rod is all existing technology and will not be described in detail here.
[0058] like Figure 4 As shown, the two front and rear integrated frames 1 have multiple insertion slots 435 arranged equidistantly from left to right on their opposite surfaces, and insertion blocks 436 are provided at both the front and rear ends of the insertion frame 432.
[0059] The distance between the plug-in bracket 432 and the adjacent transverse sliding seat 430 is changed by inserting the plug-in blocks 436 on the plug-in bracket 432 into different plug-in slots 435. These different distances set the desired left and right movement distance of the integrated frame 3 driven by the hydraulic push rod. It should be noted that when the receiver 433 receives the signal emitted by the transmitter 434, it determines the distance between the two. The control circuit controls the working displacement of the hydraulic push rod according to the different distances, thereby controlling the left and right movement distance of the integrated frame 3, and ultimately controlling the lateral distance of the conveying pipe 400's zigzag movement. This expands the area for material distribution during the repositioning and feeding, resulting in uniform material distribution and promoting uniform deposition.
[0060] like Figure 4 and Figure 5As shown, both the upper and lower ends of the front integrated frame 1 are equipped with vertically oriented moving rods 440 that slide up and down through an L-shaped frame. U-shaped baffles 441 are fixedly installed on the opposite sides of the two moving rods 440. Insertion rods 442 for penetrating adjacent support rods 2 are fixedly installed on the baffles 441. The moving rods 440 are driven to move up and down by an external cylinder.
[0061] Using the rear end face of the front integrated frame 1 and the two closed baffles 441 as two trajectory references, two intersecting folding cutting trajectories are formed. (See reference...) Figure 6 .
[0062] like Figure 4 and Figure 6 As shown, a movable plate 443 is slidably arranged on the plug-in frame 432, and all receivers 433 are fixedly arranged on the left end face of the movable plate 443. A reference plate 444 that cooperates with the integrated frame 1 and the baffle 441 is fixedly arranged on the movable plate 443.
[0063] The reference plate 444 contacts the rear end face of the front integrated frame 1 and executes the first feeding trajectory. The reference plate 444 contacts the two baffles 441 after they are closed and executes the second feeding trajectory. The moving plate 443 is driven to move back and forth by an external electric push rod (not shown in the figure).
[0064] Initially, the two baffles 441 are located on the side where the upper and lower support rods 2 are far apart. At this time, the reference plate 444 is in contact with the rear end face of the integrated frame 1, and the material feeding operation begins. At this time, the back-and-forth movement trajectory of the integrated frame 3 is the first type of zigzag feeding trajectory. After repeating the above feeding process multiple times, the external cylinder works, causing the moving rod 440 to drive the baffles 441 to move. The two baffles 441 move closer to each other, causing the plug rod 442 to pass through the support rod 2. Finally, the two baffles 441 form the reference for the second type of feeding trajectory. Then, the moving plate 443 drives the receiver 433 and the reference plate 444 on it to move backward. When the external electric push rod works, it causes the moving plate 443 to drive the reference plate 444 to move, so that the reference plate 444 contacts the baffle 441, and the second type of feeding process begins. After repeating the above feeding process, the second type of zigzag feeding trajectory is formed. The peaks of the two types of zigzag feeding trajectories intersect each other, increasing the coverage area of the feeding area, improving the uniformity of the tailings slurry distribution after feeding, promoting uniform deposition, and avoiding the problem of excessive local accumulation.
[0065] It should be added that, before the operation, the receiver 433 is manually fixed to the moving plate 443, and the distance between two adjacent receivers 433 is adjusted to meet the needs of the integrated frame 3 to move back and forth. The above distances have been obtained by existing technicians through multiple experiments and are existing technology, so they will not be described in detail.
[0066] Compared to the existing technology of direct discharge through pipelines, the integrated frame 3 avoids continuous discharge from the same location, which would impact the dam surface and affect the stability of the dam. Furthermore, the diversion unit 41 further reduces the impact on the dam. Although the addition of the feeding mechanism 4 and the diversion unit 41 increases the cost compared to the existing technology, these are all common mechanical components that can be used multiple times. From a long-term economic perspective, the increased equipment cost of this invention compared to the existing technology is negligible.
