[0028] Its function is: through the angle adjustment mechanism 3, the two tapered pipes 1 can be freely rotated in the cone surface along the axial direction. When it is used in the slurry conveying pipeline, it is convenient to adjust the variable angle of the pipeline during the installation process, so that the pipeline can be compensated at multiple angles during use. At the same time, the two tapered pipes 1 are sealed and connected through the flexible sealing ring 2, so that during the angle adjustment process, the two tapered pipes 1 are always sealed and connected, preventing slurry leakage during the adjustment process, reducing friction at the connection port of the tapered pipe 1, and extending the service life of the tapered pipe 1.

[0029] The utility model is simple to install, easy to disassemble and replace at a later time, and simple and convenient to operate. Ordinary on-duty personnel can complete the adjustment of this device, which is beneficial to improving the daily safety management of tailings transportation, and is more beneficial to ensuring production continuity and avoiding secondary environmental problems. At the same time, due to the simple installation and operation, and the simple use method, the requirements for the installation and use environment are low, so the placement of the structure is almost unrestricted, which is convenient for site selection and construction.

[0030] One end of the tapered pipe 1 disclosed in this embodiment is a small end, and one end of two tapered pipes 1 has the same diameter. The other end of the tapered pipe 1 is coaxially provided with a connecting ring 4, which can be a flange for connecting with the extension pipe. The inlet and outlet flanges fix the tapered pipe 1.

[0031] Specifically, the angle adjustment mechanism 3 includes two support rings 3-1 respectively sleeved on two conical pipes 1 near one end thereof, and at least two adjustment rods 3-2 are connected between the two support rings 3-1;

[0032] Its function is as follows: the two support rings 3-1 are used to limit and support the two tapered pipes 1 respectively, and the angle of the elbow can be adjusted by adjusting the length of the two adjustment rods 3-2.

[0033] The at least two adjustment rods 3 - 2 disclosed in this embodiment are evenly arranged along the circumference of the support ring 3 - 1, so that the connection force between the two support rings 3 - 1 is more stable.

[0035] A spherical pad 3-3 is provided at the connection between the adjusting rod 3-2 and the supporting ring 3-1 disclosed in this embodiment, and is fixed by a fixed shaft 3-4, and the fixed shaft 3-4 is a nut. When adjusting the angle, the spherical pad 3-3 can play a buffering role between the adjusting rod 3-2 and the supporting ring 3-1, reducing the impact and damage to the adjusting rod 3-2 and the supporting ring 3-1 caused by vibration and deformation of the equipment.

[0038] Its function is to facilitate the variable angle adjustment of the pipeline during installation, so that the pipeline can be compensated at multiple angles during use. At the same time, the two tapered pipes 1 are sealed and connected through a flexible sealing ring 2, so that during the angle adjustment process, the two tapered pipes 1 are always sealed and connected to prevent slurry leakage during the adjustment process, reduce friction at the connection port of the tapered pipe 1, and extend the service life of the tapered pipe 1.

[0039] The overall pipeline is simple to install, easy to disassemble and replace later, and simple and convenient to operate. Ordinary on-duty personnel can complete the adjustment of this device, which is conducive to improving the daily safety management of tailings transportation, and is more conducive to ensuring production continuity and avoiding secondary environmental problems.
