Description

Technical Field

[0001] This utility model relates to the field of mine tailings treatment technology, and in particular to a flocculant dosing device for mine tailings treatment. Background Technology

[0002] In the mining process, tailings treatment is a crucial step. To accelerate the settling of suspended solids in tailings, flocculants are typically added. However, traditional flocculant dosing devices suffer from several problems. For example, the dosage is difficult to control precisely, leading to poor flocculation, wasting flocculants, and affecting subsequent tailings treatment processes. Some devices also exhibit uneven mixing of the flocculant and tailings slurry, resulting in incomplete flocculation. Furthermore, some existing devices are prone to clogging after prolonged operation, making maintenance difficult and severely impacting the efficiency and continuity of mine tailings treatment. Therefore, this paper presents a flocculant dosing device for mine tailings treatment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a flocculant dosing device for mine tailings treatment. The controller module works in conjunction with a metering pump to precisely control the flocculant dosage, adapting to different working conditions and improving the stability of the flocculation effect. Compared to traditional dosing devices, it reduces flocculant waste and improves tailings treatment quality. The designed stirring components ensure uniform initial mixing while preventing floc destruction, allowing for a more complete flocculation reaction and improved treatment efficiency. A second servo motor drives the spiral conveyor to rotate, ensuring stable and continuous material discharge, preventing blockages, and ensuring continuous operation of the device. This provides a strong guarantee for the efficient and stable treatment of mine tailings, overcoming the shortcomings of existing technologies.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A flocculant dosing device for mine tailings treatment includes a support platform 1, a mixing cylinder 6 fixed in the middle of the support platform 1, a top cover 3 at the upper end of the mixing cylinder 6, a storage tank 4 fixed on one side of the upper end of the top cover 3, a metering pump 15 installed on the outer wall of the storage tank 4, a suction pipe 16 connected to the suction end of the metering pump 15 connected at one end to the bottom of the storage tank 4, a discharge pipe 17 connected to the discharge end of the metering pump 15 connected at one end to the top of the mixing cylinder 6 extending from the top cover 3, a stirring assembly installed in the middle of the top cover 3, a controller module 5 installed on the support platform 1, and the metering pump 15 electrically connected to the controller module 5.

[0021] The stirring assembly includes a first servo motor 10 fixed in the middle of the upper surface of the top cover 3. The output end of the first servo motor 10 extends to the bottom of the top cover 3 and is equipped with a rotating rod 11. Stirring rods 12 are fixed at equal intervals on the bottom outer wall of the rotating rod 11. Feeding ports 2 are provided on the top cover 3 on both sides of the first servo motor 10.

[0023] The anti-blocking mechanism includes a feeding pipe 7 fixed at the lower end of the discharge valve 14. A second servo motor 13 is installed on the outer wall of the closed end of the feeding pipe 7. The output end of the second servo motor 13 extends into the interior of the feeding pipe 7 and is equipped with a spiral conveying rod 8.

[0024] First, the staff adds flocculant to the storage tank 4. When the tailings processing begins, the tailings slurry flows from the feed port 2 into the mixing drum 6. The controller module 5 controls the metering pump 15 to accurately output flocculant to the mixing drum 6 based on the relevant parameters of the tailings slurry in the tailings treatment pool. At the same time, the first servo motor 10 can be turned on, driving the rotating rod 11 and the stirring rod 12 to rotate, so that the flocculant and tailings slurry are fully mixed. The mixed material enters the feeding pipe 7 through the discharge valve 14. The second servo motor 13 drives the screw conveyor 8 to rotate, so that the material is discharged stably and continuously, avoiding blockage.
