Description

Technical Field

[0001] This invention relates to the technical field of tailings and slag treatment, specifically to a tailings and slag reuse and concentration treatment device. Background Technology

[0002] In tailings dry stacking processes, thickening is typically required. This process involves adding flocculants to the slurry and stirring, followed by static settling to separate the solids and liquids, thus achieving dewatering. However, traditional thickening processes often encounter problems during dewatering: due to variations in the amount of tailings slurry delivered to the thickening tank and its initial moisture content, the height of the boundary between the sediment layer and the clear water layer after mixing with flocculants also varies. Existing suction port structures and positions are fixed, making it difficult to target and absorb the clear water layer at different depths. This results in some batches of slag having a portion of clear water remaining above the sediment after dewatering, failing to be discharged in time. Ultimately, this leads to some batches of slag having a high moisture content, which is detrimental to subsequent dry stacking of the slag.

[0003] Chinese invention patent CN116282828B discloses a tailings slag reuse and concentration treatment device, including a support frame, a receiving base installed on the upper end of the support frame, a concentration tank slidably disposed inside the receiving base, a lifting cylinder connecting the receiving base and the concentration tank, a stirring component located inside the concentration tank connected to the receiving base via a first fixing frame, water absorption modules evenly arranged around the perimeter of the concentration tank, the water absorption modules being squeezed and fitted with the inner sidewall of the receiving base, and a controllable opening / closing port provided at the lower end of the concentration tank, with a conveying module corresponding to the position of the opening / closing port installed at the lower end of the receiving base. This invention can solve the problems that after mixing and stirring with flocculant, the height of the boundary between the sediment layer and the clear water layer after settling is different, and the existing water intake structure and position are fixed, making it difficult for the existing water intake position to target the absorption of clear water layers of different depths.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: The patent can not only target water absorption for clear water layers of different depths through the water absorption module, but also improve the water removal rate of sediment. However, when the sealing frame in the water absorption module enters the storage base, the sealing frame is not completely in the clear water layer. The lower half of the sealing frame may be embedded in the sediment, and the sediment will seep in from the bottom of the sealing frame. This makes it impossible for the water delivery pipe assembly to use the buoyancy of the clear water layer to absorb water for clear water layers of different depths, thus reducing the water absorption effect of the clear water layer. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8 The present invention will describe the above technical solution in detail through the following embodiments: A tailings slag recycling and concentration treatment device includes a support frame 1 and a concentration tank 2. The concentration tank 2 is equipped with a stirring assembly 8, which has several fixed brackets 81. The top of the support frame 1 is equipped with a receiving base 3, which includes a wide opening 31, an inclined constricted opening 32, and a narrow opening 33 arranged sequentially from top to bottom. A mounting cylinder 331 is located at the bottom center of the narrow opening 33, and a lifting electric push rod 332 is installed inside the mounting cylinder 331. Two equally angled connecting pipes 333 are arranged around the mounting cylinder 331 at the bottom of the narrow opening 33. One end of each connecting pipe 333 penetrates the bottom of the narrow opening 33, and a conveying pump 334 is installed on the connecting pipe 333. A filter press assembly 9 is installed on the other end of the connecting pipe 333. The bottom of the concentration tank 2 is provided with two docking mechanisms 4 that connect with the docking pipe 333. The outer wall of the concentration tank 2 near its top is provided with several water suction mechanisms 5 for absorbing water from the clear water layer and a receiving mechanism 6 that simultaneously puts all the water suction mechanisms 5 into the concentration tank 2. The lower half of the outer wall of the concentration tank 2 is provided with several water pumping mechanisms 7 for absorbing water from the sediment. All the water pumping mechanisms 7 are connected to all the water suction mechanisms 5. The fixing frame 81 is fixedly connected to the top of the wide mouth 31. The concentration tank 2 is slidably mounted on the inner wall of the wide mouth 31. The output end of the lifting electric push rod 332 is fixedly connected to the bottom of the concentration tank 2. The inner walls of the inclined constriction part 32 and the narrow mouth part 33 are squeezed and cooperated with the water pumping mechanism 7.

[0023] It is worth noting that the stirring assembly 8 and the filter press assembly 9 in this invention have the same structure as the stirring assembly and filter press assembly in a tailings slag reuse and concentration treatment device in CN116282828B. The stirring assembly 8 includes a sealing cover, a drive motor, a stirring paddle and an inlet. Guide sliders are also evenly installed on the outer wall of the concentration tank 2, and guide rails that slide and cooperate with the guide sliders are also evenly installed on the inner wall of the wide opening 31. All of the above are existing technologies.

[0024] The present invention can release all the water-absorbing mechanisms 5 through the release mechanism 6, so that the water-absorbing mechanisms 5 can gradually contact the top surface of the clear water layer without worrying about the water-absorbing mechanisms 5 getting embedded in the sediment. The water-absorbing mechanisms 5, together with the release mechanism 6, can absorb water from the clear water layer at different depths, improving the water absorption effect of the clear water layer. The entire concentration tank 2 can be driven to move down by the lifting electric push rod 332. During the downward movement, all the water-pumping mechanisms 7 can enter the sediment. The water-absorbing mechanisms 5 and the water-pumping mechanisms 7 can also extract the water from the sediment through their cooperation.

[0025] The water suction mechanism 5 includes a floating water suction head 51 and a water pump 52. The tail end of the floating water suction head 51 is connected to a flexible tube 53. The tail end of the flexible tube 53 is equipped with a connecting head 54. The top and bottom of the connecting head 54 are respectively provided with an upper connecting pipe 541 and a lower connecting pipe 542 connected to the connecting pipe. The side walls of both sides of the connecting head 54 are provided with side sliders 543. The outer wall of the concentration tank 2 near its top is provided with a sealing perforation for the flexible tube 53 to pass through. The outer wall of the concentration tank 2 near its top is provided with two symmetrically arranged suspension tracks 21 that slide in cooperation with the side sliders 543. The sealing perforation is located between the two suspension tracks 21. The floating water suction head 51 is located inside the concentration tank 2. The water pump 52 is installed on the take-up and release mechanism 6. The upper connecting pipe 541 is connected to the water pump 52 through a pipe, and the lower connecting pipe 542 is connected to the water pumping mechanism 7 through a pipe.

[0026] The water pump 52 can absorb the clean water in the clear water layer. The floating suction head 51 can float on the clear water layer. The floating suction head 51 can be released by the retraction mechanism 6. The flexible tube 53 can be a PVC hose or a PU hose. The two suspension slides 21 and the two side slides 543 cooperate to guide the movement direction of the connecting head 54.

[0027] The suction mechanism 5 also includes a mounting plate 55 for supporting the floating suction head 51 and a sealing cover 56 that abuts against the mounting plate 55. The mounting plate 55 is horizontally set on the inner wall of the concentration tank 2, and the sealing cover 56 is set on the stirring assembly 8. The floating suction head 51 is frustoconical. When the lifting electric push rod 332 does not drive the concentration tank 2 to move down, the mounting plate 55 and the sealing cover 56 can protect the floating suction head 51. Since the floating suction head 51 is frustoconical, when the floating suction head 51 is reset, the floating suction head 51 can more easily climb to the top of the mounting plate 55 using its back. When the lifting electric push rod 332 drives the concentration tank 2 to move down, the mounting plate 55 and the sealing cover 56 can be separated.

[0028] The receiving and discharging mechanism 6 includes a rotating platform 61, an annular rotating plate 62, and a drive assembly 63 for driving the annular rotating plate 62 to rotate. There are three rotating platforms 61. The annular rotating plate 62 has several arc-shaped guide grooves 621 for sliding of the upper pipe 541. The upper pipe 541 is provided with a limiting ring 5411. Three suspensions 22 are provided on the outer wall of the concentration tank 2 near its top. The three rotating platforms 61 are detachably fixed on the three suspensions 22. The annular rotating plate 62 is rotatably mounted on the three rotating platforms 61. The drive assembly 63 is mounted on the outer wall of the concentration tank 2 and is connected to the annular rotating plate 62 in a transmission manner. All water pumps 52 are respectively mounted on the three rotating platforms 61.

[0029] The drive assembly 63 includes a rotating bracket 631, a rotating shaft 632, an arc-shaped rack 633, and a vertical rack 634. There are two rotating brackets 631. A worm gear 635 is mounted on the rotating shaft 632. A synchronizing gear 636 is provided at one end of the rotating shaft 632. The two rotating brackets 631 are symmetrically arranged on the outer wall of the concentration tank 2. The rotating shaft 632 is rotatably mounted on the two rotating brackets 631. The arc-shaped rack 633 is arranged on the outer wall of the annular rotating plate 62 and meshes with the worm gear 635. The vertical rack 634 is arranged on the inner wall of the wide opening 31. The synchronizing gear 636 selectively meshes with the vertical rack 634.

[0030] When the lifting electric push rod 332 drives the concentration tank 2 to move downward, the synchronous gear 636 can gradually abut against the vertical rack 634. After the synchronous gear 636 meshes with the vertical rack 634, it can rotate. The synchronous gear 636 drives the rotating shaft 632 and the worm gear 635 to rotate. The worm gear 635 drives the arc rack 633 to rotate. The arc rack 633 drives the annular rotating plate 62 to rotate. After the annular rotating plate 62 rotates, it can drive all the upper pipes 541 to move in all the arc guide grooves 621 respectively. The limiting ring 5411 can ensure that the upper pipes 541 move in a vertical state. Then, the upper pipes 541 drive the connecting head 54 to move towards the outer wall of the concentration tank 2 on the two suspension slides 21.

[0031] The pumping mechanism 7 includes a pumping tank 71, a pumping pipe 72, and a first spring 73. The top of the pumping tank 71 is provided with an upper connector 711, and the bottom of the tail end of the pumping tank 71 is provided with a lower support plate 712. The outer wall of the bottom end of the lower support plate 712 is provided with a diagonal bracing plate 713 that presses against the inner wall of the inclined constriction portion 32 and the narrow opening portion 33. The end of the diagonal bracing plate 713 is provided with an arc-shaped edge. Two pumping pipes 72 are provided, with the head end of each pumping pipe 72 being a closed end. Several openings are formed on the outer wall of the pumping pipe 72 near its head end. The filter holes 721 are evenly distributed. A filter cloth is installed on the inner wall of the water pumping pipe 72 near its head. Two guide rings 23 are opened on the outer wall of the concentration tank 2 to guide and cooperate with the water pumping pipe 72. The tail ends of the two water pumping pipes 72 are connected to the head end of the water pumping tank 71. The upper connector 711 is connected to the lower connector 542 through a pipe. The two ends of the first spring 73 are fixedly connected to the outer wall of the concentration tank 2 and the lower support plate 712, respectively. A limiting protrusion 722 is also provided on the outer wall of the water pumping pipe 72 near its head.

[0032] When the lifting electric push rod 332 drives the concentration tank 2 to move down, the inclined support plate 713 gradually comes into contact with the inclined constriction part 32. Then the inclined support plate 713 is squeezed by the inclined constriction part 32 and moves towards the concentration tank 2. The inclined support plate 713 drives the lower support plate 712, the water tank 71, and the two water pipes 72 to move synchronously. The two water pipes 72 are gradually inserted into the sediment. The first spring 73 is also compressed. When the water pump 52 is working, it can also extract water from the sediment. The filter hole 721 and the filter cloth can intercept and filter solid particles.

[0033] When the pumping pipe 72 is not inserted into the sediment, the filter holes 721 are completely covered by the guide ring 23, which has a sealing effect on all filter holes 721. The limiting protrusion 722 serves to limit the position of the pumping pipe 72 when it is reset.

[0034] The inner wall of the narrow opening 33 is provided with an annular bar 335 that is pressed and fitted with the inclined support plate 713. The cross-section of the annular bar 335 is semi-circular. When the inclined support plate 713 and the annular bar 335 are about to abut, the lifting electric push rod 332 can drive the concentration tank 2 to move back and forth, moving up and down. The speed of the back and forth movement should not be too fast, so that the inclined support plate 713 and the annular bar 335 abut against each other, thereby allowing the water pumping pipe 72 to extend and retract a short distance. When the water pumping pipe 72 extends, it can push the contacting sediment forward synchronously. When the water pumping pipe 72 retracts, there will be a gap at the head of the water pumping pipe 72. At the same time, the sediment in other positions quickly fills the gap, that is, the sediment flows, which improves the effect of water absorption of the sediment.

[0035] Both pumping pipes 72 have inclined surfaces 723 at their ends, and the two inclined surfaces 723 are symmetrically arranged, which can improve the flow effect of sediment.

[0036] The docking mechanism 4 includes a telescopic tube 41 and a second spring 42. The top of the telescopic tube 41 is provided with a sealing plate 43. Several feed ports 411 are provided on the outer wall of the telescopic tube 41 near its top, arranged at equal angles around its circumference. The bottom outer wall of the telescopic tube 41 is provided with a connecting protrusion ring 44. The bottom inner wall of the telescopic tube 41 is provided with an inner step 412 that abuts against the docking tube 333. The inner bottom wall of the concentration tank 2 is provided with a sealing port 24 that matches the sealing plate 43. The bottom of the concentration tank 2 is provided with a telescopic groove 25 that slides with the telescopic tube 41 and a support slide 26 that slides with the telescopic tube 41. The sealing port 24, the telescopic groove 25 and the support slide 26 are connected sequentially from top to bottom. The second spring 42 is sleeved on the telescopic tube 41, and the two ends of the second spring 42 are fixedly connected to the bottom of the concentration tank 2 and the connecting protrusion ring 44, respectively.

[0037] After the lifting electric push rod 332 drives the concentration tank 2 to move down into the narrow opening 33, the connecting pipe 333 gradually enters the telescopic pipe 41. After the connecting pipe 333 abuts against the inner step 412, the connecting pipe 333 can move up against the telescopic pipe 41. The telescopic pipe 41 and the sealing plate 43 protrude from the bottom wall of the concentration tank 2. The connecting pipe 333, the telescopic pipe 41 and the concentration tank 2 are connected. The conveying pump 334 can extract and convey the sediment, that is, extract and convey the slag. Compared with the existing technology, the docking method of the connecting pipe 333 and the telescopic pipe 41 has better sealing performance and avoids slag leakage.

[0038] Working principle: First, connect the outlets of all water pumps 52 to external pipes. Then, add tailings slurry and flocculant to the thickening tank 2. Mix the two through the stirring assembly 8. Then, the lifting electric push rod 332 drives the thickening tank 2 to move downwards within the wide opening 31. The stirring paddle in the stirring assembly 8 gradually moves away from the bottom wall of the thickening tank 2 until the stirring paddle is in the upper half of the thickening tank 2. At this point, the lifting electric push rod 332 stops working. After static treatment, the solid particles agglomerate and settle under natural gravity. The upper part becomes clear water. The liquid is separated, and the stirring paddle is located in the clear water layer. Then, the lifting electric push rod 332 continues to drive the concentration tank 2 to move downward. The synchronous gear 636 gradually meshes with the vertical rack 634, and then the synchronous gear 636 rotates. The synchronous gear 636 drives the rotating shaft 632 and the worm gear 635 to rotate. The worm gear 635 drives the arc rack 633 and the annular rotating plate 62 to rotate. After the annular rotating plate 62 rotates, it can drive all the upper pipes 541 to move in all the arc guide grooves 621 respectively. The upper pipes 541 drive the connecting head 54 to move in the two suspension slides 2. 1. Moving upwards towards the outer wall of the concentration tank 2, all floating suction heads 51 float on the clear water layer. After the synchronous gear 636 disengages from the vertical rack 634, the annular rotating plate 62 stops rotating. Then, the inclined support plate 713 gradually abuts against the inclined constriction section 32. Subsequently, the inclined support plate 713 is squeezed by the inclined constriction section 32 and moves towards the concentration tank 2. The inclined support plate 713 drives the lower support plate 712, the water tank 71, and the two water pipes 72 to move synchronously. The two water pipes 72 gradually insert into the sediment. The first spring 73 is also compressed. The water pump 52 operates, which not only removes the clear water from the clear water layer, but also extracts water from the sediment. After the water extraction is completed, the lifting electric push rod 332 continues to drive the concentration tank 2 to move down. The two connecting pipes 333 are gradually inserted into the two telescopic pipes 41. Then, the inner step 412 is used to lift the telescopic pipes 41, and the top of the telescopic pipes 41 can protrude from the inner bottom wall of the concentration tank 2. Then, the conveying pump 334 operates to convey the slag to the filter press assembly 9. Then, the filter press assembly 9 squeezes the water out of the slag.
