Description

Technical Field

[0001] This utility model relates to the field of mine waste treatment, and in particular to a mine waste drying and pelletizing machine. Background Technology

[0002] Mining and mineral processing generate large amounts of fine-particle waste residue. This residue typically has a high moisture content and fine particle size. Direct stockpiling not only occupies a significant amount of land but also poses risks of dust and leachate pollution. Currently, the common treatment method for this type of waste residue is to first dry it before granulation or briquetting to facilitate transportation and resource utilization.

[0003] The existing technology can be referenced from Chinese authorized utility model patent CN214233926U, which specifically describes a slag drying and pelletizing machine. It includes an inclined rotating hub driven by an electric motor. One end of the hub has a slurry injection port, and the other end has a discharge port. The slurry injection port includes a spray gun and a gas inlet at one end of the hub. The spray gun injects waste slag into the hub, while high-temperature flue gas enters the hub through the gas inlet, evaporating the moisture from the waste slag to form slag. Several lifting plates are installed on the inner wall of the hub. The slag falls onto the lifting plates, and under the repeated agitation of the plates, it forms large slag particles that are discharged from the discharge port. After the initial drying to form small slag particles, subsequent waste slag is continuously injected, adhering to the surface of the small slag particles. Driven by the lifting plates, the small slag particles are repeatedly lifted, causing their diameter to continuously increase, forming slag balls. The entire process is completed within the rotating hub, making it simple to operate and highly efficient. The aforementioned prior art has the following shortcomings in actual operation: the position of the drying component is not reasonably set in actual use. During the process of evaporating the moisture in the waste residue using the flue gas temperature, the moisture in the waste residue sprayed by the spray gun evaporates quickly, resulting in a low waste residue ball forming rate and relatively loose material. When the waste residue balls are collected or moved, they easily turn into granular material, which is not easy to transport and the waste residue cleaning cost is high. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a mine waste slag drying and pelletizing machine to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a mine waste drying and pelletizing machine, comprising: a right support frame with a right support ring connected to its top; The inner wall of the right support ring is rotatably connected to a forming cylinder, and a heating chamber is opened inside the forming cylinder. An electric heating plate is connected to the outer side of the heating chamber, and a heat-conducting plate is connected to the inner side of the heating chamber.

[0006] Furthermore, a flow guide hole is provided at the center of the inside of the forming cylinder, and a spiral groove is provided on the outside of the flow guide hole.

[0007] Furthermore, a right sealing cover is connected to the right side of the forming cylinder, and a discharge pipe is connected to the right side of the right sealing cover. The discharge pipe is connected to one end of the spiral groove.

[0008] Furthermore, a toothed block is connected to the right side of the surface of the forming cylinder, and a gear is meshed with the front side of the toothed block.

[0009] Furthermore, a rotating shaft is connected to the right side of the gear, a motor is connected to the right side of the rotating shaft, a fixed frame is connected to the right side of the motor, and one side of the fixed frame is connected to the lower right side of the right support frame.

[0010] Furthermore, a connecting plate is connected to the front side of the right support frame, and a controller is connected to the front side of the connecting plate.

[0011] Furthermore, a left support ring is rotatably connected to the left side of the forming cylinder surface, and a left support frame is connected to the bottom of the left support ring.

[0012] Furthermore, a support plate is connected to the left side of the left support frame, and a left sealing cover is connected to one end of the support plate. The inner wall of the left sealing cover is rotatably connected to the left side of the forming cylinder. A sealing ring is provided at the connection between the left sealing cover and the forming cylinder. A discharge cylinder is connected to the left side of the left sealing cover, and the discharge cylinder is connected to the left side of the spiral groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The rotation range of the forming cylinder is limited by the right support ring at the top of the right support frame. The heat generated by the electric heating plate is conducted to the inside of the forming cylinder by the heat conduction plate in the heating chamber. The waste residue evaporates its internal moisture by contacting the inner wall of the forming cylinder after the temperature rises during the rolling process. This ensures that the time for the waste residue ball to be formed and discharged is consistent with the time for the moisture in the waste residue to evaporate to the target value. This reduces the possibility of the waste residue ball loosening, improves the waste residue ball forming rate, and prevents the waste residue ball from becoming granular during movement or transportation, thereby reducing the cleaning cost of the waste residue treatment process.
