Description

Technical Field

[0001] This utility model relates to the technical field of tailings slurry treatment agent co-treatment equipment, specifically a device for co-injection of cyanide-containing tailings slurry treatment agents. Background Technology

[0002] The treatment of cyanide-containing tailings slurry typically involves three stages: oxidation, sedimentation, and flocculation. During the oxidation stage, oxidants and pH adjusters are mainly added. Sufficient reaction time and vigorous mixing are ensured. After oxidation is largely complete, heavy metal precipitants and necessary pH adjusters are added, and good mixing is ensured again for sedimentation. In the flocculation stage, flocculants are added to promote the aggregation and settling of the precipitate.

[0003] Therefore, the treatment of cyanide-containing tailings slurry requires the addition of various agents such as acidifiers, oxidants, and neutralizers in stages. The physical properties of different agents, including viscosity and corrosivity, vary significantly. For example, high-viscosity agents need to be atomized to improve reaction efficiency; agents containing suspended particles need to be added to prevent clogging; and low-viscosity agents need to be uniformly dispersed.

[0004] Different physical properties of reagents require different addition methods, and the addition method needs to be changed according to the properties of the reagents to ensure better addition and reaction. However, traditional reagent addition methods cannot be adapted to the characteristics of various reagents, which can lead to uneven dosing, clogging, or atomization failure, directly affecting the dosing effect. In view of this, we propose a co-dosing device for reagents in the treatment of cyanide-containing tailings slurry. Utility Model Content

[0028] 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.

[0029] Please see Figures 1-8 A device for co-doping reagents in the treatment of cyanide-containing tailings slurry includes a reaction tank 1 for treating the cyanide-containing tailings slurry. A rotating rod 2 is rotatably mounted inside the reaction tank 1, and multiple rotating blades 3 arranged in a circular array are fixedly mounted on the surface of the rotating rod 2 for stirring the cyanide-containing tailings slurry during treatment, thereby enhancing treatment efficiency.

[0030] Multiple inlet pipes 4 are fixedly connected to the top of the reaction vessel 1. These inlet pipes 4 are used for the staged addition of various reagents. A valve 5 is fixedly installed on each inlet pipe 4; this valve 5 is a metering valve, allowing for precise adjustment of the reagent addition amount. An adjusting mechanism 6 is provided between the inlet pipes 4, valves 5, and rotating rod 2. This mechanism 6 can adjust the size of the inlet nozzle 10 during reagent addition according to the type of reagent, creating multiple orifice diameters: a large orifice diameter for anti-clogging (suitable for lime slurry); a small orifice diameter for atomization (suitable for concentrated sulfuric acid); and a medium orifice diameter for uniform dispersion (suitable for hydrogen peroxide).

[0031] Please see Figures 3-8 The adjusting mechanism 6 includes a dispensing pipe 7, which is fixedly installed at the bottom end of the inlet pipe 4 and is in fixed communication with the inlet pipe 4. A rotating pipe 8 is rotatably installed inside the dispensing pipe 7 and is in communication with the dispensing pipe 7. The rotating pipe 8 is fixedly installed at the top end of the rotating rod 2 so that the rotating pipe 8 can rotate synchronously with the rotating rod 2. At the same time, the medicine enters the dispensing pipe 7 through the inlet pipe 4 and then enters the rotating pipe 8 through the dispensing pipe 7. The rotation of the rotating pipe 8 will not affect the dispensing pipe 7.

[0032] Multiple spray rods 9 are fixedly installed on the bottom of the rotating tube 8. The multiple spray rods 9 are arranged in a circular array. Multiple inlet nozzles 10 are fixedly installed at the bottom of the spray rods 9. The multiple inlet nozzles 10 are arranged in an array, which makes the spraying of the agent more uniform.

[0033] An adjusting rod 12 is slidably installed inside the spraying rod 9. Multiple adjusting blocks 11 are fixedly installed at the bottom end of the adjusting rod 12. The adjusting blocks 11 are adapted to the inlet nozzle 10. The adjusting blocks 11 are frustum structures with a larger upper part and a smaller lower part, so that the spacing of the inlet nozzle 10 can be adjusted by adjusting the position of the adjusting blocks 11 inside the inlet nozzle 10, thereby adjusting the orifice diameter of the inlet nozzle 10.

[0034] An adjusting rod 12 is fixedly connected to the top of the adjusting block 11. The adjusting rod 12 passes through the top of the spraying rod 9 and is fixedly connected to the adjusting frame 13. The adjusting frame 13 is slidably connected to the rotating tube 8. The rotation of the rotating tube 8 can drive the spraying rod 9 to rotate. The rotation of the spraying rod 9 drives the adjusting rod 12 to rotate. The rotation of the adjusting rod 12 drives the adjusting frame 13 and the rotating tube 8 to rotate synchronously.

[0035] The adjustment frame 13 can move along the rotating tube 8 to drive the adjustment rod 12 to move, and the adjustment rod 12 can drive the adjustment block 11 to move. The adjustment block 11 can adjust the orifice diameter of the drug inlet nozzle 10.

[0036] A sealing tube 14 is slidably installed inside the rotating tube 8. The bottom end of the surface of the sealing tube 14 is fixedly connected to the adjusting rod 12, so that when the adjusting rod 12 moves, it will drive the sealing tube 14 to move synchronously, so that the medicine will not enter the top of the adjusting rod 12.

[0037] It should be noted that the adjusting frame 13 and the spray bar 9 are elastically connected by a spring. The spring force ensures that the adjusting frame 13 is always away from the spray bar 9 without external force, thus keeping the spray nozzle 10 at its maximum opening.

[0038] Please see Figures 6-8 Multiple sliding frames 19 are fixedly installed at the top of the reaction vessel 1. A sliding rod 17 is slidably installed through the sliding frame 19. A support frame 20 is fixedly installed on the surface of the sliding rod 17 near its top. The sliding frame 19 and the support frame 20 are elastically connected. The spring force keeps the support frame 20 away from the sliding frame 19, so that the sliding rod 17 always has an upward tendency to move. This ensures that when not in operation, the sliding rod 17 will not affect the adjusting frame 13.

[0039] A clamping frame 16 is fixedly installed at the bottom end of the sliding rod 17. A clamping wheel 15 is rotatably installed inside the clamping frame 16, and the clamping wheel 15 is in contact with the adjusting frame 13. The position of the adjusting frame 13 can be adjusted by the displacement of the clamping wheel 15, and the clamping wheel 15 can rotate, thereby reducing the friction between the adjusting frame 13 and the clamping wheel 15 when rotating. This improves the service life of the device.

[0040] An arc-shaped block 18 is provided at the top of the sliding rod 17, and the arc-shaped block 18 contacts the valve 5. When the valve 5 is opened, the arc-shaped block 18 can be squeezed, the arc-shaped block 18 drives the sliding rod 17 to move downward, the sliding rod 17 moves downward, thereby driving the clamping frame 16 to move downward, the clamping frame 16 moves downward, driving the clamping roller 15 to move downward, the clamping roller 15 moves downward, squeezing the adjusting frame 13 to move downward, thereby adjusting the orifice diameter of the drug inlet nozzle 10.

[0041] It should be noted that the sliding rods 17 have a consistent length, while the clamping rollers 15 have different diameters. This ensures that when different valves 5 are opened, the sliding rods 17 and clamping rollers 15 move downwards to the same position. Because the diameters of the clamping rollers 15 are inconsistent, the squeezing distance of the clamping rollers 15 on the adjusting frame 13 is different. Therefore, the downward movement distance of the adjusting frame 13 can be varied according to different drug feeding materials, thereby allowing adjustment of the orifice diameter of the drug feeding nozzle 10.

[0042] A co-application device for treating cyanide-containing tailings slurry, the working principle of which is as follows:

[0043] When medication needs to be added, valve 5 is opened. When valve 5 is open, it compresses the arc-shaped block 18. The arc-shaped block 18 causes the sliding rod 17 to move downwards, which in turn causes the clamping frame 16 to move downwards. The clamping frame 16 then causes the clamping wheel 15 to move downwards, which in turn compresses the adjusting frame 13. When the adjusting frame 13 moves downwards, it causes the adjusting rod 12 and the adjusting block 11 to move downwards simultaneously. By adjusting the position of the adjusting block 11 within the medication nozzle 10, the discharge orifice diameter of the medication nozzle 10 can be adjusted. The inconsistent diameters of the clamping wheels 15 result in varying compression distances between the clamping wheels 15 and the adjusting frame 13, leading to different orifice diameters of the medication nozzle 10 when different valves 5 are opened.

[0044] The reagent enters the filling pipe 7 through the inlet pipe 4 and valve 5, and then enters the rotating pipe 8 through the filling pipe 7. Since the rotating pipe 8 is connected to the spray rod 9, the reagent enters the spray rod 9 and is finally sprayed out into the reaction tank 1 through the inlet nozzle 10 to participate in the reaction. At the same time, the rotation of the rotating rod 2 drives the rotating blade 3 and the rotating pipe 8 to rotate synchronously, and the rotation of the rotating blade 3 plays a stirring role. The rotation of the rotating pipe 8 drives the spray rod 9 and the inlet nozzle 10 to rotate synchronously, which achieves uniform drug delivery and makes the drug delivery and reaction faster and more uniform.
