Description

Technical Field

[0001] The utility model belongs to the technical field of mining tailings transportation, and in particular relates to an anti-sedimentation device for a long-distance tailings transportation pipeline. Background Art

[0002] In recent years, due to the rise of mining, the number of mines has increased day by day, and tailings are one of the necessary and important products in mineral processing operations. Tailings refer to the part of the product of the sorting operation in mineral processing that has a low content of useful target components and cannot be used for production. The tailings generated in the mineral processing process will cause great harm to the environment, so it is necessary to centrally recover and discharge them into a fixed tailings pond. In general mining enterprises, the distance between the tailings pond and the mineral processing plant is relatively long, and most of the terrain environments are relatively complex, and there is even a large drop between the two. Therefore, in many mining enterprises, the use of multi-stage pumping stations for transportation has become the only solution. However, due to the long-distance tailings pipeline transportation, the tailings sand gradually deposits as the distance increases and the flow rate decreases, which makes the tailings pipeline very easy to be blocked, thus causing environmental problems. Nowadays, most mining enterprises stop production and stop the pipeline for pipeline blockage problems, and flush the blocked pipeline with flushing water of the same diameter and equal flow rate. This method is not only time-consuming and labor-intensive, but also requires reduction and suspension of production. At the same time, there are also large unsafe factors, and there are great risks in the implementation process. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an anti-sedimentation device for long-distance tailings conveying pipelines, which can solve the technical problems of sedimentation blockage and time-consuming and labor-intensive disassembly and cleaning of existing long-distance tailings conveying pipelines.

[0037] The anti-deposition device is installed at an uphill position of a long-distance tailings conveying pipeline.

The rotating conveying pipeline 1 is connected to the adjacent pipeline through a rotating socket bearing 3. The rotating socket bearing 3 can ensure that the rotating conveying pipeline 1 rotates around the central axis of the pipeline relative to the adjacent pipeline. The gear ring 4 is stationary relative to the rotating conveying pipeline 1. The power assembly 2 provides the rotating conveying pipeline 1 with rotational power through the gear ring 4. After the slurry conveyed by the long-distance tailings conveying pipeline enters the device, the slurry is also rotated under the rotation of the rotating conveying pipeline 1. Under the action of the rotational force, the concentration of each layer of the slurry is more uniform, and the flow rate is increased at the same time, thereby preventing the slurry from settling due to the decrease in flow rate and then clogging the pipeline.

[0042] As a preferred scheme of this embodiment, the rotating conveying pipeline 1 in this embodiment includes a pipeline body 11, and connecting pipes 12 with a frustum structure are integrally arranged at both ends of the pipeline body 11.

The end faces of both ends of the pipeline body 11 are top-connected with the end faces of the connector 312, and the connecting pipe 12 is inserted into the bearing inner ring 31. During use and cleaning, the connecting pipe 13 with a frustum structure can quickly realize the installation and disassembly between the rotating socket bearing 3 and the rotating conveying pipeline 1, which can greatly reduce labor costs and time costs.

[0043] Preferably, in this embodiment, the taper of the connecting pipe 12 is greater than the taper of the inner ring body 311, so as to facilitate the adjustment of installation errors.

[0044] As a preferred solution of this embodiment, a pair of flanges 5 are connected to a plurality of equally spaced bolt rods 6 in this embodiment.

[0048] In actual operation of this embodiment:
