[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a composite tailings bin system includes a tailings bin 1, in which a flow sedimentation zone 2 and a dosing sedimentation zone 3 are fixed on the left and right sides of the top of the tailings bin 1 in sequence, and a filling slurry zone 4 is provided at the bottom of the flow sedimentation zone 2 and the dosing sedimentation zone 3, and the filling slurry zone 4 is fixed at the bottom of the tailings bin 1, the flow first output end of the flow sedimentation zone 2 is fixedly connected to the dosing sedimentation zone 3, the dosing first output end of the dosing sedimentation zone 3 passes through the tailings bin 1 and is fixedly connected to the collecting tank, the flow second output end and the dosing second output end of the flow sedimentation zone 2 and the dosing sedimentation zone 3 are respectively fixedly connected to the filling slurry zone 4, the flow sedimentation zone 2 can naturally settle the tailings slurry flow, and the dosing sedimentation zone 3 can dosing and precipitate the tailings slurry flowing into the flow sedimentation zone 2, the filling slurry zone 4 is also connected to a cement bin through a connecting pipe, and a diversion component is fixed at the filling output end of the filling slurry zone 4.

[0025] Specifically, the tailings bin 1 is the main part of the entire system, used to accommodate and preliminarily process the tailings slurry. The flow settling area 2 is located on the top left side of the tailings bin 1. Its main function is to perform preliminary flow settling treatment on the incoming tailings slurry. Through the action of gravity, larger particles in the tailings slurry will naturally settle to the bottom, while finer suspended matter will continue to flow with the water flow. Preliminary settling helps reduce the load of subsequent processing steps.

[0026] The dosing sedimentation zone 3 is located immediately after the flow sedimentation zone 2 and is located on the top right side of the tailings bin 1. In the dosing sedimentation zone 3, specific chemical agents (such as flocculants) are added to the tailings slurry that has undergone preliminary sedimentation to promote the rapid sedimentation of suspended matter. These agents can form larger flocs with the suspended matter, thereby accelerating its sedimentation process.

[0027] The filling slurry area 4 is located at the bottom of the tailings bin 1 and is used to receive and mix the tailings slurry after flow sedimentation and dosing sedimentation. Here, the tailings slurry is mixed with cement or other additives from the cement bin to form a filling slurry. This filling slurry can be used for mine backfill, dam construction or other engineering applications;

[0028] The system also includes connecting pipes and diversion components for transporting materials such as tailings slurry and cement from one area to another, while the diversion components are responsible for directing the prepared filling slurry to the required location.

[0029] The flow sedimentation area 2 includes a flow sedimentation tank body 5, a feed assembly is provided on the top of the flow sedimentation tank body 5, and the input end of the feed assembly is externally connected to a beneficiation tailings slurry discharge device. The feed assembly can input tailings slurry with a concentration of 15.81% into the sedimentation tank body. The bottom surface of the sedimentation tank body is inclined in the tailings bin 1. A guide assembly is fixed at the bottom of the flow sedimentation tank body 5. The guide assembly can divert the tailings slurry after precipitation in the flow sedimentation tank body 5. The side end of the top of the flow sedimentation tank body 5 is fixedly connected to the overflow water diversion pipe, and the overflow water diversion pipe passes through The flow sedimentation tank body 5 is fixedly connected to the dosing sedimentation area 3, and a pump body is fixed on the overflow water guide pipe; the feeding assembly includes an L-shaped feeding conduit 6, which is inserted into the feeding hole 7 and can slide in the feeding hole 7. A telescopic hose 8 is fixedly connected to the L-shaped feeding conduit 6, and the telescopic hose 8 is fixedly connected to a connecting pipe. The connecting pipe is fixedly connected to the flow sedimentation tank body 5 through a bracket. An electric push rod 9 is fixedly connected to the side of the L-shaped feeding conduit 6, and the electric push rod 9 is fixed to the top of the flow sedimentation tank body 5;

[0030] Specifically, the main function of the feed assembly is to introduce the tailings slurry (with a concentration of 15.81%) generated during the mineral processing process into the flow settling tank body 5 .

[0031] The L-shaped feed conduit 6 is inserted into the flow settling tank body 5 through the feed hole 7 and can slide in the feed hole 7. At the same time, the telescopic property of the telescopic hose 8 is used to activate the electric push rod 9, so that the L-shaped feed conduit 6 can reciprocate in the feed hole 7, so that the tailings slurry can evenly enter the flow settling tank body 5;

[0032] At the same time, after ensuring that the tailings slurry can be evenly and stably injected into the flow settling tank 5, in actual application, an intelligent liquid level sensor can also be introduced to monitor the liquid level in the tank in real time and feed the data back to the central control system. Once the liquid level approaches the preset warning line, the central control system will automatically adjust the operating frequency of the electric push rod 9, thereby adjusting the reciprocating speed of the L-shaped feed conduit 6 to ensure that the feed rate matches the processing capacity of the settling tank.

[0033] The bottom of the flow settling tank 5 is inclined toward the tailings bin, which helps the sediment (such as tailings) formed during the settling process of the tailings slurry to slide down and settle along the bottom. In the flow settling tank 5, the solid particles in the tailings slurry gradually settle to the bottom due to gravity, while the clear water (or water with less solids) gradually rises and gathers at the top of the flow settling tank 5.

[0034] The material guide assembly is located at the bottom of the flow settling tank 5 and is used to guide the tailings slurry after sedimentation;

[0035] The overflow water diversion pipe is fixed to the top side of the flow sedimentation tank body 5, passes through the flow sedimentation tank body 5 and is fixedly connected to the dosing sedimentation area 3. A pump body is also installed on the pipeline to realize the diversion drive function;

[0036] That is, when the clean water in the flow sedimentation tank body 5 accumulates to a certain height, it flows into the dosing sedimentation area through the overflow water diversion pipe for further treatment (such as dosing sedimentation, etc.). The presence of the pump body can ensure that the clean water can be discharged in a timely and effective manner to avoid excessive accumulation in the sedimentation tank body.

[0037] A layered filter assembly is fixed in the flow sedimentation tank body 5, and the layered filter assembly is arranged at the upper end of the bottom surface, and can filter the tailings slurry after precipitation in layers; the layered filter assembly includes two layers of filter screens 10 arranged in the flow sedimentation tank body 5 from top to bottom, and the apertures of the two layers of filter screens 10 are gradually reduced from top to bottom. Both sides of the filter screens 10 pass through the flow sedimentation tank body 5 and are fixedly connected to the limit plates, and a spring is fixed between the limit plates on one side and the side walls of the flow sedimentation tank body 5, and a vibrator 11 is fixed on the limit plate; a discharge assembly is fixed to the upper end of each layer of filter screen 10, and the discharge assembly can discharge the tailings slurry precipitated by the filter screen 10, and a discharge assembly is also fixed to the bottom of the flow sedimentation tank body 5, and the output end of the discharge assembly is inserted into the filling slurry area 4;

[0038] Specifically, a layered filter assembly is fixedly installed above the bottom surface of the flow settling tank 5. The main function of the layered filter assembly is to filter the tailings slurry after sedimentation in layers to separate solid particles of different sizes.

[0039] The layered filtration assembly includes two layers of filter screens 10, which are obliquely arranged in the flow sedimentation tank body 5 and arranged from top to bottom. The mesh apertures of the two layers of filter screens 10 gradually decrease, which means that the aperture of the upper layer of filter screen 10 is larger, which can allow larger particles to pass through, while the aperture of the lower layer of filter screen 10 is smaller, which can further filter out smaller particles.

[0040] To maintain the stability and position of the filter 10, both sides of the filter extend through the flow settling trough 5 and are fixedly connected to limit plates. These limit plates not only secure the filter but are also connected to the side walls of the flow settling trough 5 via springs. This allows the filter to move slightly when subjected to vibration while maintaining its overall position.

[0041] In addition, in order to enhance the filtering effect, a vibrator 11 is fixed to the limit plate on one side. The vibrator 11 can generate vibrations to make the solid particles on the filter 10 fall off more easily, thereby improving the filtering efficiency.

[0042] At the upper end of each layer of filter screen 10, a discharge assembly is fixed. The function of these discharge assemblies is to discharge the tailings slurry settled on the filter screen in time to prevent it from accumulating too much and affecting the filtering effect. At the same time, these discharge assemblies can also be transported to the filling slurry area 4 as needed for filling slurry preparation;

[0043] A discharge assembly is also fixed at the bottom of the flow settling tank 5, and its output end is directly inserted into the filling slurry area 4, so as to directly transport the filtered fine particle tailings slurry to a designated area for subsequent processing.

[0044] Two partition plates 12 are fixed in sequence from left to right in the flow sedimentation tank body 5, and the heights of the two partition plates 12 are lowered from left to right, and the cross-section of the partition plates 12 is triangular; the discharge assembly includes a multi-way pipe 13, and a valve is fixed on the output end of the multi-way pipe 13. Each branch of the multi-way pipe 13 is fixedly connected to the area between the partition plate 12 and the filter screen 10, and can discharge the tailings slurry precipitated by the filter screen 10 to the filling slurry area 4.

[0045] Specifically, in the flow sedimentation tank body 5, two partition plates 12 are fixed in sequence from left to right, and the height of the two partition plates 12 gradually decreases from left to right. This design helps the slurry to gradually settle during the flow process. The cross-section of the partition plate 12 is designed to be triangular, which helps the slurry to generate turbulence or eddy current when flowing through, thereby promoting the sedimentation of mineral particles.

[0046] A valve is fixed on the output end of the multi-way pipe 13 to control the flow rate and timing of discharge. Each branch pipe is fixedly connected to the area between the partition plate 12 and the filter screen 10, allowing the tailings slurry to be discharged to the filling slurry area 4 through different branches after the slurry passes through the filter screen 10 and the tailings slurry is precipitated.

[0047] The dosing sedimentation area 3 includes a dosing tank body 14 whose inner bottom surface is inclined toward the tailings bin 1. The dosing tank body 14 is fixed in the tailings bin 1, and an overflow water diversion pipe is fixedly connected to the side of the dosing tank body 14. The output end of the overflow water diversion pipe is connected to the dosing tank body 14 using a multi-way branch pipe. A first stirring assembly and a dosing pipe 15 are fixed on the top of the dosing tank body 14. The dosing pipe 15 is arranged at the side end of the first stirring assembly. A discharge conduit is fixed to the bottom of the dosing tank body 14, and a valve is provided on the discharge conduit. A drainage conduit is fixed to the side end of the top of the dosing tank body 14, and the drainage conduit passes through the dosing tank body 14 and the tailings bin 1. The first stirring assembly includes a fixed plate 16, a sliding frame 17, a sliding assembly, a first stirring member and a driving assembly 27. The sliding frame 17 is fixed on the fixed plate 16, and the sliding frame 17 is slidably connected to the sliding assembly. The first stirring member is fixed on the sliding assembly, and the sliding assembly is fixedly connected to the output end of the driving assembly 27. The driving assembly 27 is fixed on the fixed plate 16. The driving assembly 27 can drive the sliding assembly to slide back and forth on the sliding frame 17 and drive the first stirring member to reciprocate in the dosing tank 14; the sliding assembly includes a positioning frame 1 8. Both ends of the positioning frame 18 are respectively embedded in the slide grooves on the sliding frame 17 and are slidably connected to the sliding frame 17. A positioning block 19 is slidably connected to the positioning frame 18. A first stirring member is fixed on the front side of the positioning block 19, and a positioning groove 20 is fixed on the other side. A spring is provided in the positioning groove 20, and the spring is fixedly connected to the limit block 21. The limit block 21 can be inserted into the positioning groove 20. The limit block 21 fits and is embedded in the slide rail assembly, and the slide rail assembly is fixed to the positioning frame 18; the slide rail assembly includes two vertical slide rails 22 and a cross slide rail 23. The two vertical slide rails 22 are fixedly connected with a cross slide rail 23, and a convex plate 24 is fixed on the lower part of each vertical slide rail 22 at the connection with the cross slide rail 23, and the top of the convex plate 24 is set with an inclined surface, and the distance between the bottom of the convex plate 24 and the bottom of the vertical slide rail 22 is greater than twice the outer diameter of the limit block 21; the first stirring assembly includes a first stirring motor, the first stirring motor is fixed on the positioning block 19, and the output end of the first stirring motor is fixedly connected to a first stirring shaft 25, and the first stirring shaft 25 is fixed with a first stirring shaft 25 from top to bottom. The stirring blade 26, the first stirring blade includes two blade plates that are fitted and fixed, and the blade plates are arranged in a "fish fin shape", with multiple through holes fixed on the blade plates, and the through holes on the two blade plates are staggered; the driving assembly 27 includes a first connecting rod, a second connecting rod and a driving motor, one end of the first connecting rod is rotatably connected to one end of the second connecting rod through a rotating shaft, the other end of the first connecting rod is hinged to the positioning frame 18 through a hinge shaft, and the other end of the second connecting rod is fixedly connected to the output end of the driving motor, and the driving motor is fixed on the fixed plate 16.

[0048] Specifically, the dosing tank body 14 is fixed in the tailings bin 1, and its inner bottom surface is tilted toward the tailings bin 1, which facilitates the mixing and settling of the reagent and tailings. The overflow water diversion pipe is used to divert excess water flow, and its output end is connected to the dosing tank body 14 through a multi-way branch pipe to ensure smooth water flow. The dosing pipe 15 is used to add reagent to the dosing tank body 14 and is arranged at the side end of the first stirring assembly. The first stirring assembly is used to stir the reagent and tailings in the dosing tank body 14 to ensure that they are fully mixed.

[0049] Specifically, the first stirring assembly is fixed with a sliding frame 17 on the fixed plate 16 to provide support for the stirring assembly, and both ends of the positioning frame 18 are embedded in the sliding grooves of the sliding frame 17 to achieve a sliding connection;

[0050] The slide rail assembly consists of two vertical slide rails 22 and a cross slide rail 23, providing a complex sliding path of up and down - left and right - up and down - left and right to ensure the stirring effect;

[0051] The bottom of the vertical slide rail 22 has an inclined convex plate 24, which cooperates with the force of the limit block 21 and the spring to enable the limit block 21 to slide normally in the slide rail assembly;

[0052] That is, when the limit block 21 slides down from a vertical slide rail 22, the limit block 21 will contact the convex plate 24. Because the top of the convex plate 24 is inclined, it can ensure that the limit block 21 contacts the convex plate 24, producing an effect, causing the spring to compress, and the limit block 21 slides into the positioning groove 20.

[0053] Because each vertical slide rail 22 is fixed with a protruding plate 24 at the connection with the cross slide rail 23, and the top of the protruding plate 24 is set with an inclined surface, and the distance between the bottom of the protruding plate 24 and the bottom of the vertical slide rail 22 is greater than twice the outer diameter of the limit block 21, when the limit block 21 slides away from the protruding plate 24, the spring takes effect and causes the limit block 21 to pop out;

[0054] When the limit block 21 slides to the bottom of the vertical slide rail 22, it will be limited by the convex plate 24 when sliding upward, so that the limit block 21 slides into the cross slide rail 23. Similarly, the other vertical slide rail 22 will also produce the same movement, driving the first stirring element to achieve a complex sliding path of up and down - left and right - up and down - left and right, thereby improving the stirring effect.

[0055] The first stirring motor drives stirring through the first stirring shaft 25 and the first stirring blade 26. The blade plate is set in a "fish fin shape" and has multiple through holes. The through holes on the two blade plates are staggered, which helps to enhance the stirring effect and mixing uniformity.

[0056] The driving assembly 27 includes a first connecting rod, a second connecting rod and a driving motor; the driving motor drives the positioning frame 18 to slide back and forth on the sliding frame 17 through the second connecting rod and the first connecting rod, thereby realizing the reciprocating motion of the stirring element. This reciprocating motion combined with the complex path of the slide rail assembly can further improve the stirring effect and the sedimentation efficiency of the tailings.

[0057] The filling slurry area 4 includes a guide area and a stirring area. The guide area is fixedly arranged on the stirring area. The guide area includes two guide plates 28 that are relatively fixed on the inner wall of the tailings bin 1.
