Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a deep zinc removal treatment device for acidic wastewater from mines. Background Technology

[0002] Acidic wastewater from mines is acidic wastewater containing various heavy metal ions generated during the mining process, among which zinc ions are one of the common pollutants. If this type of wastewater is discharged directly without treatment, it will not only pollute the soil and water bodies, but may also pose a threat to the ecological environment and human health through the food chain.

[0003] Existing mine acidic wastewater treatment equipment uses a neutralization precipitation method. This method involves adding alkaline agents to the wastewater to adjust the pH value, causing zinc ions to form hydroxide precipitates. Solid-liquid separation is then achieved through filtration. This type of equipment generally includes a reaction tank and a filtration device. Its working principle is as follows: wastewater enters the reaction tank through the feeding system, where it reacts fully with the agents under stirring to generate precipitates. Subsequently, the wastewater flows into the filtration device, where the precipitates are intercepted by the filter plates, and the treated wastewater is discharged after meeting the standards.

[0004] However, existing acidic wastewater treatment equipment for mines uses a single shaft drive, which has a limited stirring range and insufficient mixing uniformity, resulting in insufficient zinc ion reaction and difficulty in improving zinc removal efficiency. Therefore, a deep zinc removal treatment equipment for acidic wastewater in mines is proposed to solve the above problems. Utility Model Content

[0044] Working principle: When deep zinc removal treatment is required for acidic mine wastewater, motor 11 starts, and its output drives the drive gear 7 to rotate. The drive gear 7 meshes with two driven gears 8, and the driven gears 8 mesh with the gear ring 9, causing the driven gears 8 to perform planetary motion around the drive gear 7. This, in turn, drives the bottom stirring rod 10 to rotate synchronously. The dosing device 14 adds zinc removal agent to the treatment tank 1. The rotation of the stirring rod 10 achieves efficient mixing and stirring of the wastewater and the agent, promoting a thorough and uniform zinc removal reaction. After the reaction is completed, the transfer pump 4 starts, pumping the wastewater in the treatment tank 1 to the top of the filter tank 2 through the transfer water pipe 5. After entering the filter tank 2, the filter plate 15 filters the wastewater, trapping the zinc precipitate generated in the reaction, thus achieving solid-liquid separation.

[0045] When the filter plate 15 needs to be cleaned or replaced, pull the handle 23. The handle 23 moves the limit block 22 and the pull rod 20 to the right. When the pull rod 20 moves, it compresses the spring 21, causing the locking block 19 to disengage from the slot 16 of the filter plate 15. At this time, the filter plate 15 can be easily removed from the filter box 2 through the handle 17. After cleaning or replacement, put the filter plate 15 into the filter box 2, release the handle 23, and the elastic force of the spring 21 pushes the locking block 19 to the left, re-locking it into the slot 16 of the filter plate 15, thus completing the fixation of the filter plate 15. The whole process does not require the use of tools, which improves maintenance efficiency.
