[0002] The treatment and utilization of tailings has always been a crucial component in the development and utilization of mineral resources. As the residual material left after ore extraction, tailings contain a large number of valuable components and usable resources, but they can also cause certain environmental pollution. Therefore, how to effectively treat and utilize tailings has become a pressing issue in the mining industry.

[0003] Tailings filling technology is a commonly used tailings treatment method. It mixes tailings with an appropriate amount of filler material (such as cement and sand) and then fills it into mine goafs or abandoned mines. This not only solves the problem of tailings storage but also improves mine stability and prevents geological disasters such as ground collapse. However, tailings filling technology faces many challenges in its practical application.

[0004] Secondly, during the filling process, tailings often require the addition of an appropriate amount of flocculant to improve their fluidity and facilitate mixing with the filler material. However, the addition of flocculants can cause problems such as sticking to the inner wall of the mixing barrel and uneven mixing, which not only increases the difficulty of mixing but also may affect the quality of the filler.

[0005] Therefore, in order to solve the shortcomings of the above problems, a stirring device for tailings filling is proposed. Summary of the Invention

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0029] like Figure 2 As shown, a stirring device for tailings filling comprises: a stirring barrel 1, a stirring mechanism 6 arranged in the stirring barrel 1, and a protective shell 2 arranged on one side of the stirring barrel 1;

[0030] like Figure 3As shown, the stirring mechanism 6 includes: two connecting rings 602, a connecting rod 601 arranged between the two connecting rings 602, a plurality of scraping rods 604 arranged between the two connecting rings 602, a plurality of stirring plates 606 arranged on the outer wall of the connecting rod 601, and a motor 608 arranged on one side of the stirring barrel 1;

[0031] Two connecting rings 602 are located in the mixing barrel 1, and a motor 608 is fixedly connected to one side of the mixing barrel 1. A plurality of fixing rods 603 are fixedly connected to the inner circumference of the two connecting rings 602. The other ends of the plurality of fixing rods 603 are fixedly connected to the same fixing block 609. One end of the output shaft of the motor 608 passes through the mixing barrel 1 and is fixedly connected to one side of one of the fixing blocks 609. The connecting rod 601 is fixedly connected between the two fixing blocks 609. A plurality of stirring plates 606 are fixedly connected to the outer circumference of the connecting rod 601. A plurality of through slots 607 are formed on one side of the plurality of stirring plates 606.

[0032] One side of several scraping rods 604 is fixedly connected to a reinforcement rod 605, and the other end of the reinforcement rod 605 is fixedly connected to the circumferential outer wall of the connecting rod 601. The outer walls of several scraping rods 604 are tightly fitted with the circumferential inner wall of the mixing barrel 1, and the circumferential outer walls of the two connecting rings 602 are tightly fitted with the circumferential inner wall of the mixing barrel 1.

[0033] It should be noted that efficient stirring of the tailings and flocculant is achieved through the combination of the connecting rod 601, the stirring plate 606, and the through-slots 607. The through-slots 607 on the stirring plate 606 can increase the fluid dynamics during stirring, allowing the materials to be more fully mixed during the stirring process, thereby improving stirring efficiency and uniformity, thereby helping to ensure the quality of the tailings filling and avoiding poor filling effects caused by uneven stirring.

[0034] Scraper rod 604 is fixedly connected to connecting rod 601 via reinforcing rod 605, and its outer wall closely fits the circumferential inner wall of mixing drum 1. During the mixing process, scraper rod 604 continuously scrapes away material adhering to the inner wall of mixing drum 1, effectively preventing flocculant from sticking. This not only improves mixing efficiency but also ensures that mixing drum 1 remains clean even after long-term use, reducing maintenance costs.

[0035] like Figure 1-Figure 3 As shown, a protective shell 2 is fixedly connected to one side of the mixing barrel 1, the motor 608 is located inside the protective shell 2, a plurality of penetrating heat dissipation holes 7 are provided on the circumferential outer wall of the protective shell 2, a pipe on one side of the mixing barrel 1 is connected to a feed hopper 4, a pipe on the circumferential outer wall of the mixing barrel 1 is connected to a discharge hopper 5, and a plurality of supporting legs 3 are connected to the circumferential outer wall of the mixing barrel 1.

[0036] It should be noted that by placing the motor 608 in the protective shell 2, the motor 608 can be protected from interference and damage from the external environment, thereby improving the safety of the entire stirring device. In addition, the presence of the protective shell 2 effectively prevents the splashing or noise that may be generated by the motor 608 during operation from affecting the operator. At the same time, the protective shell 2 is provided with a number of through-holes 7 for heat dissipation. During the long-term operation of the motor 608, the heat generated can be discharged in time through the heat dissipation holes 7, effectively avoiding the performance degradation or failure caused by overheating of the motor 608. The hopper 4 can be easily poured into the mixing barrel 1, while the discharge hopper 5 ensures that the stirred material can be discharged smoothly, avoiding the problem of material blockage or leakage.

[0037] When using the present invention, tailings and an appropriate amount of flocculant are sequentially added to the mixing barrel 1. During stirring, the motor 608 is started, and the output shaft of the motor 608 drives the stirring mechanism 6 to begin rotating. The connecting rod 601, the stirring plate 606, and the scraper 604 act together on the material in the mixing barrel 1. The through groove 607 on the stirring plate 606 increases the fluid dynamics during stirring, allowing the material to be more fully mixed during the stirring process. The scraper 604 continuously scrapes off the material adhering to the inner wall of the mixing barrel 1 to prevent the flocculant from sticking and maintain the cleanliness of the mixing barrel 1. After stirring is completed, the motor 608 is turned off, and the valve of the discharge hopper 5 is opened to allow the stirred material to be smoothly discharged from the mixing barrel 1.

[0038] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
