DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0018] like Figures 1 to 11 As shown, a mining and smelting waste slag heap leachate collection tank described in this embodiment includes a collection tank 1, a storage tank 2 and a collection pipe 3 connected between the collection tank 1 and the storage tank 2; a filter screen 4 is provided at the opening position of the collection tank 1; and an anti-blocking filter device 5 is connected in series to the collection pipe 3; The anti-blocking filter device 5 comprises a filter seat 51, a drive seat 52 disposed in the filter seat 51 and an anti-blocking structure 54 disposed in the filter seat 51; a filter screen structure 53 is disposed at one end of the filter seat 51; a filter element 55 is disposed at the other end of the filter seat 51; the inner wall surface of the drive seat 52 is an elliptical wall surface 521; The filter structure 53 includes a plurality of filter frames 532 which are arranged side by side and slidably at intervals; The anti-blocking structure 54 includes a plurality of drive pins 547 which are arranged side by side at intervals and are elastically movable. One end of the drive pin 547 is provided with a conical portion 5471 which is movably embedded between two adjacent filter skeletons 532. The other end of the drive pin 547 is movably abutted against the elliptical wall surface 521 of the drive seat 52. The drive pin 547 can rotate along the trajectory of the elliptical wall surface 521 of the drive seat 52.

[0019] Specifically, when the leachate collection pool for the mining and smelting waste slag pile of this embodiment is actually used, the waste slag pile is placed in the collection tank 1, and the leachate flows into the collection tank 1 after being filtered through the filter net 4, and then flows to the storage tank 2 through the collection pipe 3. When the leachate flows through the collection pipe 3, the leachate passes through the anti-blocking transition device. After the leachate enters the filter seat 51, it is first filtered by the filter structure, and then filtered by the filter element 55 and flows out to the collection pipe 3, and then flows into the storage tank 2 through the collection pipe 3.

[0020] When clearing is required, the collecting pipe 3 is closed, and the driving pin 547 is rotated along the trajectory of the elliptical wall surface 521 of the driving seat 52, so that the driving pin 547 extends toward the filter frame 532. Since the driving pin 547 is provided with a tapered portion 5471, the driving pin 547 squeezes the filter frame 532 during the extension process, so that the distance between adjacent filter frames 532 increases, that is, the sieve hole diameter of the filter structure 53 increases, so that large particles of impurities stuck in the gap of the filter frame 532 fall off; After cleaning, the driving pin 547 is rotated in the opposite direction along the trajectory of the elliptical wall 521 of the driving seat 52, so that the driving pin 547 retracts away from the filter skeleton 532, so that the conical portion 5471 gradually reduces the extrusion of the filter skeleton 532, thereby reducing the distance between adjacent filter skeletons 532 to ensure the filtering effect.

[0021] Similarly, this embodiment can adjust the gap of the filter skeleton 532 according to the actual flow rate of the leachate through the movement of the driving pin 547, so as to obtain a filter structure 53 with different sieve hole diameters. When the leachate flow rate is large, the sieve hole diameter is increased to ensure the smooth passage of the leachate; when the flow rate is small, the sieve hole diameter is reduced to effectively filter impurities, thereby being able to flexibly adjust the degree of filtration.

[0022] In this embodiment, the driving pin 547 is in contact with the elliptical wall 521 of the driving seat 52, so that when the driving pin 547 rotates, the driving pin 547 can be telescopically moved, so that the distance between adjacent filter skeletons 532 can be adjusted through the tapered portion 5471 of the driving pin 547, so that impurities in the gap can fall off, effectively preventing pipe blockage, and realizing automatic cleaning of the filter screen without frequent manual disassembly and cleaning, thereby saving manpower and material resources, and the filtration degree can be flexibly adjusted according to the actual flow rate of the leachate.

[0023] In order to improve the filtering and clearing efficiency, anti-clogging filtering devices 5 may be arranged at equal intervals along the length direction of the collecting pipe 3 .

[0024] like Figure 5 , Figure 6 and Figure 8 As shown, in the mining and smelting waste slag heap leachate collection pool of this embodiment, in some embodiments, the filter structure 53 also includes a mounting frame 531; the filter skeleton 532 is arranged in the mounting frame 531; and a foldable anti-corrosion film 533 is connected between the two opposite side walls of the mounting frame 531 and the two filter skeletons 532 located on the outermost sides. Specifically, the anti-corrosion film 533 can be one of a thermoplastic polyurethane elastomer rubber (TPU) film, a silicone rubber film, and a polyethylene (PE) film, and the surface is coated with an anti-corrosion layer. In this embodiment, the mounting frame 531 is provided to facilitate the installation of the filter skeleton 532, and the anti-corrosion film 533 is provided to compensate for the gap change caused by the spacing of the filter skeletons 532.

[0025] Specifically, Figure 8 As shown, the mounting frame 531 is in an arc shape, and strip sliding holes are provided at both ends of the mounting frame 531. Sliding pins are protruding at both ends of each filter skeleton 532, and the sliding pins are movably embedded in the corresponding strip sliding holes. The sliding pins cooperate with the strip sliding holes, so that the filter skeleton 532 can slide relative to the mounting frame 531 to adjust the sieve hole diameter of the filter structure 53.

[0026] like Figure 8 As shown, the number of the filter skeletons 532 can be freely set according to the actual design. For example, in the present embodiment, each filter screen structure 53 is provided with five filter skeletons 532 .

[0027] like Figures 4 to 6As shown, in the leachate collection pool for the mining and smelting waste slag heap of this embodiment, in some embodiments, the filter seat 51 includes a filter tube seat 511 and a filter cover 512; the filter tube seat 511 is connected in series to the collection pipe 3; the filter cover 512 is fixedly mounted on the filter tube seat 511 and a filter cavity is surrounded by the outer wall of the filter tube seat 511; the filter tube seat 511 is provided with an installation port and an installation cavity connected to the filter cavity; the installation frame 531 is fixed in the installation port; the filter element 55 is arranged in the installation cavity.

[0028] In this embodiment, a filter tube seat 511 and a filter cover 512 are provided to prevent the installation of the filter device 5 from being blocked; the leachate first enters the filter tube seat 511, is filtered by the filter screen structure 53, enters the filter cavity, then flows from the filter cavity into the installation cavity, is filtered by the filter element 55 in the installation cavity, and then flows out to the collection pipe 3, so that the leachate after filtration is stored in the storage tank 2.

[0029] like Figures 5 to 7 , Fig.10 and Fig.11 As shown, in the mining and smelting waste slag heap leachate collection pool of this embodiment, in some embodiments, the anti-blocking structure 54 also includes a track seat 541 fixedly mounted on the filter tube seat 511; the track seat 541 is provided with a spacing adjustment assembly; the spacing adjustment assembly includes an adjustment seat 542 fixedly mounted on the track seat 541 and two adjustment sliders 543 symmetrically slidably mounted on the track seat 541; the adjustment seat 542 is rotatably connected to the first connecting rod 544; the two adjustment sliders 543 are respectively rotatably connected to the second connecting rod 545; one end of the two second connecting rods 545 is respectively hinged to the two ends of the first connecting rod 544; the two adjustment sliders 543 are both fixed with pin seats 546; a plurality of driving pins 547 are spaced side by side and elastically movably penetrate the pin seats 546. As shown Figure 7 and Fig.11 As shown, in the mining and smelting waste slag heap leachate collection pool of this embodiment, in some embodiments, the adjustment seat 542 extends with a first connecting column; the middle of the first connecting rod 544 is provided with a connecting shaft; one end of the connecting shaft is rotatably connected to the first connecting column; the other end of the connecting shaft is rotatably passed through the filter cover 512 and connected to the motor 548. Figure 7 , Fig.10 and Fig.11 As shown, in the leachate collection pool for the slag heap of the mining and smelting waste in this embodiment, in some embodiments, a plurality of spaced-apart parallel strip holes 5461 are provided on the pin seat 546; the driving pin 547 is movable through the corresponding strip holes 5461; it is arranged so that when the tapered portion 5471 of the driving pin 547 adjusts the spacing between the filter skeletons 532, the driving pin 547 can slide adaptively in the strip hole 5461, thereby avoiding the occurrence of sticking.

[0030] Specifically, the track seat 541 is annular, and a circular track groove is provided on the track seat 541, and the adjusting slider 543 is slidably installed on the track groove; a plurality of driving pins 547 are arranged in sequence along the length direction of the pin seat 546; when it is necessary to adjust the spacing of the filter skeleton 532 or to clear the blockage, the first connecting rod 544 is driven to rotate by the motor 548, and when the first connecting rod 544 rotates, it synchronously drives the two second connecting rods 545 to rotate, and the two second connecting rods 545 respectively drive the two adjusting sliders 543 to slide, and the adjusting slider 543 drives the corresponding pin seat 546 to move, and the pin seat 546 drives the corresponding driving pin 547 to move. During the movement, the driving pin 547 contacts and cooperates with the elliptical wall surface 521 of the driving seat 52, so that the driving pin 547 moves toward the filter skeleton 532, squeezes the filter skeleton 532, and increases the spacing between adjacent filter skeletons 532, thereby adjusting the sieve aperture of the filter structure 53, so that large particles of impurities stuck in the gap of the filter skeleton 532 fall off, so as to prevent the filter structure 53 from being blocked.

[0031] like Fig.10 As shown, in the mining and smelting waste slag heap leachate collection pool of this embodiment, in some embodiments, the adjusting slider 543 is extended with a second connecting column; one end of the second connecting rod 545 is rotatably connected to the second connecting column; and the other end of the second connecting rod 545 is hinged to one end of the first connecting rod 544. In this embodiment, the second connecting column is provided to facilitate the installation of the adjusting slider 543 and the second connecting rod 545.

[0032] like Figure 7 , Fig.10 and Fig.11 As shown, in the mining and smelting waste slag heap leachate collection pool of this embodiment, in some embodiments, the other end of the driving pin 547 is provided with a round head 5472 for contacting the elliptical wall 521; the outer wall of the driving pin 547 is provided with a spring 549; the two ends of the spring 549 are respectively in contact with the round head 5472 and the pin seat 546. In this embodiment, the round head 5472 is provided to reduce the friction between the driving pin 547 and the elliptical wall 521 of the driving seat 52, so that the driving pin 547 moves more smoothly and reduces wear; the spring 549 is provided to provide a reset elastic force for the driving pin 547, so that after the elliptical wall 521 of the driving seat 52 gradually releases the squeezing of the driving pin 547, the driving pin 547 moves in a direction away from the filter frame 532 under the elastic force of the spring 549, so that the conical portion 5471 gradually releases the squeezing of the filter frame 532, and the filter frame 532 is gradually reset to the initial position under the elastic action of the anti-corrosion film 533.

[0033] In the mining and smelting waste slag heap leachate collection pool of this embodiment, in some implementations, two filter screen structures 53 are provided, and the filter tube seat 511 is symmetrically provided with two installation openings arranged opposite to each other; the two filter screen structures 53 are arranged in the two installation openings in a one-to-one correspondence; two groups of spacing adjustment components are correspondingly provided; and the two groups of spacing adjustment components are symmetrically arranged on the track seat 541. In this embodiment, by providing two filter screen structures 53 and two groups of spacing adjustment components, the filtering efficiency and the collection efficiency can be improved.

[0034] like Figures 2 to 4 As shown, the leachate collection pool for the mining and smelting waste slag heap of this embodiment, in some implementations, also includes an impurity collection box 61 and an impurity conveying pipe 62; one end of the impurity conveying pipe 62 extends into the filter seat 51; the other end of the impurity conveying pipe 62 is connected to the impurity collection box 61; an electric-controlled valve 63 is provided at one end of the impurity conveying pipe 62.

[0035] Specifically, when the filter structure 53 needs to be cleaned, the electric control valve 63 is opened, the impurity conveying pipe 62 is connected to the filter tube seat 511, and the motor 548 is started to rotate the first connecting rod 544 and the second connecting rod 545, so that the conical portion 5471 of the driving pin 547 squeezes the filter skeleton 532, thereby increasing the distance between adjacent filter skeletons 532, so that large particles of impurities stuck in the gaps of the filter skeletons 532 fall off into the impurity conveying pipe 62, and enter the impurity collection box 61 through the impurity conveying pipe 62 for storage, thereby preventing the filtered large particles of impurities from being blocked on the filter structure 53 again.

[0036] like Figure 1 and Figure 2 As shown, in the mining and smelting waste slag heap leachate collection tank of this embodiment, in some embodiments, a retaining edge 11 is provided at the outer periphery of the collection tank 1. In this embodiment, the retaining edge 11 is provided to block the leachate, so that the leachate flows into the collection tank 1 through the filter screen 4.

[0037] like Figures 1 to 11 As shown, this embodiment also provides a method for collecting leachate from the above-mentioned mining and smelting waste slag heap, which specifically includes the following steps: Step S100, preliminary site and infrastructure construction; specifically, conduct a detailed survey of the terrain around the slag heap, and determine to dig a leachate collection tank 1 at a suitable location below the slag heap and a storage pool 2 for collecting the filtered leachate at a suitable location in combination with the leachate flow direction and geological conditions. During excavation, the size of the pool body must be accurate to meet the expected leachate collection volume, and the pool wall must be reinforced and anti-seepage treated to prevent leachate leakage from causing secondary pollution to the surrounding soil and water.

[0038] According to the position of the collection tank 1 and the storage tank 2, the laying route of the leachate collection pipe 3 is planned. During the laying process, ensure that the collection pipe 3 has a certain slope to facilitate the leachate to flow into the storage tank 2 by gravity, and at the same time fix and seal the collection pipe 3 to prevent displacement and leakage of the collection pipe 3. Install the anti-blocking filter device 5 at a predetermined position in the leachate collection pipe 3, and ensure that the anti-blocking filter device 5 is firmly installed and fits tightly with the inner wall of the collection pipe 3 to prevent the leachate from passing directly without filtration.

[0039] Step S200, equipment installation and commissioning; specifically, connect the motor 548 to the power supply circuit, ensure that the line connection is correct and safe, install overload protection, leakage protection and other devices, and ensure the stable operation of the motor 548. Perform a comprehensive commissioning of the entire leachate collection tank to check whether the motor 548 operates normally, whether the driving pin 547 slides smoothly, whether the spacing adjustment of the filter frame 532 is flexible, and whether the leachate flows smoothly in the collection pipe 3.

[0040] Step S300, real-time flow monitoring and filtration adjustment; specifically, a high-precision flow monitoring device is installed at the entrance or key position of the leachate collection pipeline 3 to monitor the flow change of the leachate in real time, and transmit the flow data to the control system. The control system automatically determines whether it is necessary to adjust the sieve aperture of the filter skeleton 532 according to the preset flow threshold and the actual monitored leachate flow. When the leachate flow is greater than the set larger flow threshold, the control system sends an instruction to start the motor 548, and the motor 548 rotates forward to drive the driving pin 547 to slide, so that the driving pin 547 increases the degree of squeezing the filter skeleton 532. Under the action of the spring 549, the spacing between the filter skeletons 532 increases, thereby increasing the sieve aperture to ensure that the leachate passes quickly; when the leachate flow is less than the set smaller flow threshold, the motor 548 reverses, the driving pin 547 reduces the squeezing of the filter skeleton 532, the spacing of the filter skeleton 532 is reduced, the sieve aperture is reduced, and impurities are effectively filtered.

[0041] Step S400, regular cleaning and maintenance of the filter screen; specifically, set a time period for regular cleaning of the filter screen structure 53, and when the cleaning time is reached, start the motor 548, which drives the drive pin 547 to slide, so that the spacing of the filter frame 532 is increased, and the impurities originally stuck between the gaps of the filter frame 532 fall off and flow into the collection pool together with the leachate. After the cleaning is completed, check the filter screen structure 53 again to ensure that all components are not damaged and the connection is firm. If there is any abnormality, repair or replace it in time.

[0042] Step S500, subsequent treatment of leachate; specifically, after the leachate in the storage tank reaches a certain level, it is transported to a special leachate treatment facility by a lift pump. In the treatment facility, the leachate is purified by physical, chemical or biological treatment methods according to the composition and pollution degree of the leachate, so that it can be discharged or reused after meeting the discharge standards.

[0043] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
