[0002] Mine wastewater is a general term encompassing natural dissolved water in mines, mineral processing wastewater, overflow water from mineral processing slag dikes, and leachate from slag heaps.

[0003] Chinese patent application CN202420225158.8 discloses a wastewater treatment device for lithium mines. The key technical feature is a housing with a screen cylinder fixedly installed between the inner walls of its left and right sides. By using the screen cylinder, workers can pour wastewater into it through a feeding pipe. The workers then start a first motor, which drives a first rotating shaft to rotate. This shaft in turn drives a surface conveying auger, which pushes the wastewater and ore fragments. The wastewater flows directly through the first screen holes on the screen cylinder surface, while larger ore fragments cannot pass through and are discharged through the outlet. A screen plate is also included to collect smaller ore fragments, thus achieving the goal of classifying and collecting wastewater and ore fragments using the screen cylinder and screen plate.

[0004] In existing wastewater pretreatment equipment, the amount of wastewater in the tank varies with each batch, and the fixed amount of chemical reagents cannot meet the actual needs, which may lead to insufficient wastewater treatment or waste of chemical reagents, making it inconvenient to use. Therefore, a wastewater treatment equipment for mining is proposed to address the above problems. Utility Model Content

[0008] Preferably, the slider is slidably mounted inside the guide rail, and the partition plate has multiple discharge holes that are evenly distributed on the partition plate.

[0009] Preferably, one side of the blocking plate is in contact with one side of the partition plate, the first rack meshes with the gear, and the gear meshes with the second rack.

[0010] Preferably, a screen cylinder is fixedly connected inside the screening box, and an auger is rotatably connected inside the screen cylinder, with the side surface of the auger fitting against the inner wall of the screen cylinder.

[0011] Preferably, the liquid inlet penetrates the screening box and is fixedly connected to the side surface of the screen cylinder. The screen cylinder has multiple screen holes inside, which are evenly distributed on the screen cylinder. A filter plate is slidably connected between the stirring box and the screening box.

[0012] Preferably, a rotating shaft is fixedly and rotatably connected inside the mixing tank, and stirring blades are fixedly connected to the side surface of the rotating shaft. Multiple stirring blades are provided, and the stirring blades are evenly distributed on the rotating shaft.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a wastewater treatment device for mining operations includes a mixing tank 1, a screening box 2 fixedly installed on the mixing tank 1, a liquid inlet 3 fixedly installed on the screening box 2, a chemical storage tank 4 fixedly installed on the mixing tank 1, and a control mechanism disposed inside the mixing tank 1 for controlling the dosage of chemical each time.

[0026] The control mechanism includes a guide rail 5 fixedly installed inside the mixing tank 1, a float plate 6 disposed inside the guide rail 5, a slider 7 fixedly installed on the float plate 6, a first rack 8 fixedly installed on the float plate 6, a partition plate 13 fixedly installed inside the medicine storage tank 4, a blocking plate 9 slidably installed inside the medicine storage tank 4, a second rack 10 fixedly installed on the blocking plate 9, a fixed rod 11 fixedly installed inside the medicine storage tank 4, and a gear 12 rotatably installed on the fixed rod 11.

[0027] The slider 7 is slidably installed inside the guide rail 5, and the partition plate 13 has multiple discharge holes inside, which are evenly distributed on the partition plate 13.

[0028] One side of the blocking plate 9 is in contact with one side of the partition plate 13, the first rack 8 meshes with the gear 12, and the gear 12 meshes with the second rack 10.

[0029] During operation, the worker first pours wastewater into the screening box 2 through the inlet 3. After screening, the wastewater enters the mixing tank 1. Inside the mixing tank 1, the float 6 rises along the guide rail 5 according to the water level. The rise of the float 6 drives the first rack 8, which is fixedly connected to it, to move synchronously. The movement of the first rack 8 drives the gear 12, which meshes with it, to rotate clockwise. The rotation of the gear 12 drives the second rack 10, which meshes with it, to descend. The descent of the second rack 10 drives the block 9, which is fixedly connected to it, to descend synchronously. As plate 9 descends, partition plate 13 is exposed, and the medicine inside the storage tank 4 flows out through the discharge hole on partition plate 13. When the flow reaches the level with the exposed discharge hole, the medicine stops flowing. Therefore, the flow rate of the medicine can be changed by the water level inside the mixing tank 1. After the wastewater treatment is completed, the wastewater is discharged, and the water level begins to drop. The float plate 6, along with the slider 7, descends along the direction of the guide rail 5, finally resetting all parts and preparing for the next use. At this time, the medicine inside the storage tank 4 is filled with medicine to reduce the probability of insufficient wastewater treatment or waste of chemical agents, making it more convenient to use.

[0030] Example 2

[0031] Please see Figure 4 As shown in the first embodiment, as another implementation of the present invention, a screen cylinder 14 is fixedly connected inside the screening box 2, and an auger 15 is rotatably connected inside the screen cylinder 14. The side surface of the auger 15 is in contact with the inner wall of the screen cylinder 14.

[0032] The liquid inlet 3 penetrates the screening box 2 and is fixedly connected to the side surface of the screen cylinder 14. Multiple screen holes 16 are opened inside the screen cylinder 14 and are evenly distributed on the screen cylinder 14. A filter plate 17 is slidably connected between the mixing box 1 and the screening box 2.

[0033] During operation, the staff pours wastewater into the screening box 2 through the inlet 3, and then into the screen cylinder 14. By starting the external motor, the output shaft of the motor drives the auger 15, which is fixedly connected to it, to rotate synchronously. The rotation of the auger 15 pushes the wastewater and ore fragments. The wastewater flows directly out through the screen holes 16 on the surface of the screen cylinder 14. Larger ore fragments cannot pass through the first screen cylinder 14 and are eventually discharged along the screen cylinder 14. Smaller ore fragments and wastewater fall directly onto the surface of the filter plate 17. The wastewater can pass directly through the filter plate 17 and fall to the bottom of the mixing tank 1, while the smaller ore fragments remain on the surface of the filter plate 17 for easy collection.

[0034] The mixing tank 1 is fixedly rotatably connected to a rotating shaft 18. A stirring blade 19 is fixedly connected to the side surface of the rotating shaft 18. Multiple stirring blades 19 are provided and are evenly distributed on the rotating shaft 18.

[0035] During operation, the wastewater, after being screened by the screen cylinder 14 and the filter plate 17, enters the interior of the mixing tank 1. Then, by starting the external motor, the output shaft of the motor drives the rotating shaft 18, which is fixedly connected to it, to rotate synchronously. The rotation of the rotating shaft 18 drives multiple stirring blades 19, which are fixedly connected to it, to rotate synchronously. At the same time, the agent is added into the interior of the mixing tank 1 through the control mechanism to mix with the wastewater. The rotation of the stirring blades 19 makes the agent and wastewater mix quickly and finally discharged.
