[0025] The present utility model provides an acidic mine wastewater treatment device as shown in Figures 1-3 which includes a base 1. Two support plates 2 are fixedly connected to the upper surface of the base 1. The upper ends of the two support plates 2 are jointly fixedly connected with a treatment box 3. A cover plate 4 is slidably arranged on the upper surface of the treatment box 3. Two first rotating rods 5 are rotatably connected to the lower surface of the cover plate 4. Stirring blades 6 are fixedly sleeved on the rod walls of the lower ends of the two first rotating rods 5. A driving mechanism is arranged on the upper surface of the cover plate 4. The two first rotating rods 5 are rotated through the driving mechanism. A second rotating rod 7 is rotatably connected to the lower surface of the treatment box 3. The upper end of the second rotating rod 7 penetrates through the lower surface of the treatment box 3 and is fixedly connected with a U-shaped scraping plate 8. The U-shaped scraping plate 8 is attached to the inner wall of the treatment box 3. A transmission mechanism is arranged between the second rotating rod 7 and the driving mechanism. The driving mechanism drives the second rotating rod 7 to rotate through the transmission mechanism.

[0026] The rotation of the two first rotating rods 5 can cause the two stirring blades 6 to rotate, so that the acidic mine wastewater can fully react with the alkaline agent, thereby accelerating the reaction process. At the same time, the rotation of the second rotating rod 7 can cause the U-shaped scraper 8 to rotate, so as to scrape off the sediment adhering to the inner wall of the treatment tank 3.

[0027] To rotate the two first rotating rods 5, as Figures 1-3 shown, the driving mechanism includes two mounting plates 9, a third rotating rod 10, two first bevel gears 11, two second bevel gears 12 and a motor 13. Both mounting plates 9 are fixedly connected to the upper surface of the cover plate 4. The third rotating rod 10 is rotatably connected between the two mounting plates 9. Both first rotating rods 5 penetrate the upper surface of the cover plate 4. Two first bevel gears 11 are respectively fixedly sleeved on the rod walls of the corresponding first rotating rods 5. Two second bevel gears 12 are both fixedly sleeved on the rod wall of the third rotating rod 10 and are respectively meshed with the corresponding first bevel gears 11. The motor 13 is fixedly connected to the upper surface of the cover plate 4. One end of the third rotating rod 10 penetrates one side of the corresponding mounting plate 9 and is fixedly connected to the output end of the motor 13.

[0028] Start the motor 13 to rotate the third rotating rod 10, then the two second bevel gears 12 can be rotated, and then the two first bevel gears 11 can be driven to rotate, so that the two first rotating rods can rotate.

[0029] To rotate the second rotating rod 7, as Figures 1-2 shown, the transmission mechanism includes a fourth rotating rod 14, two sprockets 15, a chain 16, a third bevel gear 17 and a fourth bevel gear 18. The fourth rotating rod 14 is rotatably connected to the upper surface of the base 1.

The third bevel gear 17 is fixedly sleeved on the rod wall of the fourth rotating rod 14. The fourth bevel gear 18 is fixedly sleeved on the rod wall of the third rotating rod 10 and is matched with the fourth rotating rod 14. A strip hole is opened on one side of one of the support plates 2, and the strip hole is matched with the chain 16.

[0030] When the third rotating rod 10 rotates, the fourth bevel gear 18 rotates, and then the third bevel gear 17 can be driven to rotate, so that the fourth rotating rod 14 can rotate. Then, through the transmission of the two sprockets 15 and the chain 16, the second rotating rod (7) can be rotated.

[0033] When the cover plate 4 moves downward, the third bevel gear 17 can pass through the through hole and then mesh with the fourth bevel gear 18.
