Background Technology

[0002] Flocculation and sedimentation of suspended impurities are the core processes for removing insoluble suspended particles from water in water treatment, especially applicable to fields such as mine wastewater treatment. In existing technologies, the common practice for mine wastewater treatment is to mix the reagent and wastewater at high speed in a mixing tank or pipeline mixer to ensure that the reagent and wastewater come into full contact.

[0003] Regarding stirring devices, for example, Chinese invention patent with publication number CN116874055A discloses a mine wastewater treatment system. Wastewater enters the flocculation sedimentation chamber through the inlet, and is stirred by adding flocculant and stirring mechanism to settle again. The sediment is then discharged through sedimentation discharge mechanism.

[0004] However, in actual use, the device only uses the conventional method to add the agent, which causes the agent to concentrate at one point in the wastewater before the stirring begins, affecting the subsequent dispersion efficiency of the flocculant in the wastewater. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following provides a detailed description of each embodiment. This specific embodiment is merely an explanation of the present invention and is not intended to limit it. Those skilled in the art, after reading this specification, can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0022] A high-efficiency purification device for treating mine wastewater includes a stirring device and a screening device disposed above and connected to the stirring device. The screening device includes: a primary screening component and a secondary screening component, the secondary screening component being located below the primary screening component, and the primary screening component having larger screen openings than the secondary screening component; a feed box 3 for mounting the primary screening component and the secondary screening component, the inner side of the feed box 3 being provided with two opposing slide rails 23; the primary screening component includes a primary screening element slidably mounted between the two slide rails 23; the secondary screening component includes a screening plate 14 with several screen openings rotatably connected at one end to the inner wall of the feed box 3, and a cam 1 abutting against the screening plate 14. 3. An impact rod 11 is located at the off-center of the cam 13, and a rotary motor is fixedly connected to the other end of the impact rod 11 relative to the cam 13. The screening device also includes a synchronization component, which includes a rotating rod 24, pulleys 25 fixedly sleeved on the rotating rod 24 and the impact rod 11 respectively, a synchronization belt 26 between the two pulleys 25, a fourth helical gear 18 on the rotating rod 24, a third helical gear 17 meshing with the fourth helical gear 18, a vertical rod 12 on the third helical gear 17, an impact wheel 19 located at the off-center on the vertical rod 12, a retaining frame 20 sleeved on the outside of the impact wheel 19, and a connecting rod 21 on the retaining frame 20 for connecting the primary screening component.

[0023] This embodiment employs multi-stage screening, including primary vibrating screening, secondary high-frequency impact, and synchronous vibration design, to refine and uniformly disperse the reagent particles, solving the localized concentration problem caused by traditional dosing methods and significantly improving the mixing efficiency of flocculant and wastewater. After the reagent is uniformly dispersed, the stirring device can quickly complete the flocculation reaction, shortening the wastewater treatment cycle and making it suitable for mining wastewater scenarios with high suspended solids content. Furthermore, the synchronous component integrates the power transmission for primary and secondary screening, requiring only a single motor to drive both screening actions, simplifying the structure, reducing energy consumption, and minimizing the risk of mechanical failure.

[0024] The stirring device includes a stirring drum 2, a rotating drum 4 rotatably connected to the inner wall of the stirring drum 2, a fixed rod 5 fixedly connected to the inner wall of the stirring drum 2, a plurality of first helical gears 6 are sleeved on the surface of the fixed rod 5 at intervals, a second helical gear 7 is meshed on the first helical gear 6, a stirring rod 8 is fixedly connected to the axis of the second helical gear 7, a connecting gear 9 is sleeved on the surface of the rotating drum 4, a driving gear 10 is meshed on the surface of the connecting gear 9, a short rod is passed through the axis of the driving gear 10, and a drive motor is fixedly connected to one end of the short rod.

[0025] The rotating drum 4 serves as the core rotating component. Its rotation drives the components fixed to it and all the stirring rods 8 to rotate around the axis of the drum, generating a large-scale radial circulation within the drum 2. This forces the fluid to move outwards, ensuring the initial mixing of the reagents and wastewater on a radial macroscopic scale. The fixed rod 5 is fixedly connected to the inner wall of the drum 2 and remains stationary relative to it. Its core function is to serve as the mounting base for the first helical gear 6. When the second helical gear 7 moves around the axis of the fixed rod 5 along with the revolution of the stirring rods 8, the first helical gear 6, as a fixed gear ring, forces the meshing second helical gear 7 to rotate. This component converts the revolution's kinetic energy into rotational energy, thereby driving the stirring rods 8 to produce localized rotational stirring, improving the stirring effect.

[0026] The screening device also includes a spring rod 15 that abuts against the screening plate 14. The spring rod 15 is fixedly connected to the outer side of the feed box 3 by a long strip plate 16.

[0027] The spring rod 15 provides elastic restoring force to form a vibration guiding structure. When the protruding part of the cam 13 rotates away from the screening plate 14, the energy stored in the compressed spring inside the spring rod 15 is released, forcibly pushing the screening plate 14 to quickly return to the initial position. This ensures that the screening plate 14 can reliably return to its original position after being hit by the cam 13 each time, preparing for the next impact.

[0028] The primary screening component includes two slide bars, which are fixedly connected with several partition bars at intervals. Screen holes are formed between adjacent partition bars, and the slide bars are slidably connected to the inner side of the slide rail 23.

[0029] The separation strips are spaced at specific intervals, forming the sieve holes of the primary screening component. These sieve holes are significantly larger than those of the secondary screening plate. This effectively blocks large clumps of undispersed flocculant or impurities, reducing the processing pressure on the screening plate 14 and minimizing the risk of clogging. Furthermore, the separation strips greatly enhance the rigidity of the entire screening component frame, making it less prone to bending, deformation, or resonance damage under strong vibrations, thus ensuring durability and screening accuracy.

[0033] The implementation principle of the high-efficiency purification device for mine wastewater treatment in this application embodiment is as follows: 1. Start the drive motor to make the drive gear 10 rotate. The rotating drum 4 rotates under the meshing action of the drive gear 10 and the connecting gear 9. The rotation of the rotating drum 4 drives the stirring rod 8 to rotate. 2. During the rotation of the drum 4, the fixed rod 5 remains stationary, and thus the first helical gear 6 also remains stationary. During the rotation of the stirring rod 8, the second helical gear 7 moves together with the stirring rod 8. At the same time, the second helical gear 7 is meshed with the first helical gear 6, causing the second helical gear 7 to rotate. Thus, when the drum 4 rotates, the stirring rod 8 rotates together, which can mix the medicine and wastewater more evenly and improve the uniformity of mixing of the device. 3. Start the rotary motor to rotate the striking rod 11, which in turn causes the cam 13 to continuously strike the bottom of the screening plate 14. With the assistance of the spring rod 15, the screening plate 14 continuously swings up and down, pushing the material in the wastewater into the feed box 3. Figure 2 The left-hand conveyor is shown in the image; 4. While the striking rod 11 rotates, the rotation of the striking rod 11 is transmitted to the rotating rod 24 by the two pulleys and the synchronous belt 26 respectively set on the striking rod 11 and the rotating rod 24, causing the fourth helical gear 18 to rotate through the third helical gear 17, thereby causing the striking wheel 19 to continuously strike the return frame 20. The return frame 20 then moves back and forth through the connecting rod 21, causing the screening component 22 to move evenly, dispersing the material falling into the feed box 3, reducing material accumulation, and ensuring the normal screening effect of the device.
