[0036] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] refer to Figure 1At least one embodiment provides a multi-channel gas-liquid conveying rotary joint, comprising: an inner tube 1, which is connected to a feeding pipe for receiving materials to be conveyed; the inner tube 1 includes a central channel 11 and a side channel 12 for conveying different materials, for conveying multiple materials simultaneously; a bearing 2; and an outer tube 3, which includes a mounting groove 31 for mounting the inner tube 1, so that the inner tube 1 is rotatably connected to the side wall of the mounting groove 31 through the bearing 2, thereby reducing the friction between the inner tube 1 and the outer tube 3; the outer tube 3 also includes a central tube 32 and a side tube 33, both connected to the mounting groove 31, such that the central tube 32 is connected to the central channel 11 and the side tube 33 is connected to the side channel 12, for forming different material conveying channels.

[0038] In some embodiments, one end of the inner tube 1 is located inside the mounting groove 31, and the other end is located outside the mounting groove 31, for convenient connection with the feeding pipe; the outer tube 3 is connected to the receiving pipe so that the feeding pipe is connected to the receiving pipe through a rotary joint.

[0039] In some embodiments, the central channel 11 is separated from the side channel 12 to prevent mixing between different materials being transported; the central pipe 32 and the side pipe 33 are separated to transport different materials simultaneously to prevent mixing between different materials being transported.

[0040] In some embodiments, the end wall of the central channel 11 is sealed to the end wall of the central pipe 32 to prevent leakage during material conveying; the side channel 12 includes a separate first channel 13 and a second channel 14; the side pipe 33 includes a separate first pipe 34 and a second pipe 35; the first pipe 34 is connected to the first channel 13 to form a material conveying channel; the second pipe 35 is connected to the second channel 14 to form a material conveying channel.

[0041] In some embodiments, the first tube 34 and the second tube 35 are symmetrical about the central tube 32; the first channel 13 and the second channel 14 are symmetrical about the central channel 11.

[0042] In some embodiments, the cross-sections of the first pipe 34 and the second pipe 35 are circular or polygonal, i.e., circular or square; the cross-sections of the first channel 13 and the second channel 14 are fan-shaped, so that when the rotation angle between the inner pipe 1 and the outer pipe 3 is small, the first channel 13 is connected to the first pipe 34 and the second channel 14 is connected to the second pipe 35. At the same time, when the rotation angle between the inner pipe 1 and the outer pipe 3 is large, the first channel 13 is isolated from the first pipe 34, and the second channel 14 is isolated from the second pipe 35, thereby facilitating the control of material conveying.

[0043] In some embodiments, the first tube 34 and the second tube 35 are on the side of the outer casing; the first channel 13 and the second channel 14 are located in the inner tube 1 away from the central channel 11.

[0044] Working principle: Before using a multi-channel pneumatic-hydraulic conveying rotary joint, connect the inner tube 1 to the feeding pipeline; that is, connect the central channel 11, the first channel 13, and the second channel 14 to different material conveying channels in the feeding pipeline; simultaneously connect the outer tube 3 to the receiving pipeline; that is, connect the central tube 32, the first tube 34, and the second tube 35 of the outer tube 3 to different receiving tubes on the receiving pipeline; when the multi-channel pneumatic-hydraulic conveying rotary joint is used, the material provided by the feeding pipeline passes through the central channel 11, the first channel 13, and the second channel 14 to the central tube 32, the first tube 34, and the second tube 35, respectively, and finally reaches the receiving pipeline. In different receiving pipes; when using a multi-channel gas-liquid conveying rotary joint, if there is partial rotation between the inner pipe 1 and the outer pipe 3, the material can still be conveyed normally; when the rotation angle between the inner pipe 1 and the outer pipe 3 is too large, the material between the central channel 11 and the central pipe 32 can still be conveyed normally; the material between the first channel 13 and the first pipe 34 is blocked and cannot be conveyed normally; the material between the second channel 14 and the second pipe 35 also cannot be conveyed normally; when the outer pipe 3 and the inner pipe 1 rotate again, the first pipe 34 and the first channel 13 are connected again, and the second pipe 35 and the second channel 14 are also connected again; maintain the above process until the work is completed.

[0045] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
