Description

Technical Field

[0001] The utility model relates to the technical field of conveying pipelines, in particular to a wear-resistant mud conveying pipeline. Background Art

[0002] Mud is not a pure liquid medium, but a medium formed by uniform mixing of a liquid phase and a solid phase. During the conveying process, it will cause a strong impact on the pipeline and cause great wear on the inner wall of the conveying pipeline. The existing wear-resistant pipelines improve the structure of the inner wall of the pipeline to improve the overall wear resistance of the pipeline, thereby increasing the service life of the conveying pipeline. However, when the pipeline is damaged, repair or replacement is very troublesome, which is not conducive to the later maintenance work. Content of the Utility Model

[0003] The purpose of the utility model is to provide a wear-resistant mud conveying pipeline, which is used to solve the problem that it is not convenient to repair or replace the mud conveying pipeline after wear in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A wear-resistant mud conveying pipeline, including a pipeline main body, a bushing is arranged inside the pipeline main body, a wear-resistant layer is arranged inside the bushing, the outer side of the bushing is attached to the inner wall of the pipeline main body, limiting rings are arranged at both ends of the bushing, a limiting groove matching with the bushing is opened on one side of the limiting ring, the end of the bushing is arranged in the limiting groove, and the inner diameter of the limiting ring is the same as the inner diameter of the bushing.

[0005] Optionally, a steel wire layer is arranged on the outer side of the wear-resistant layer.

[0006] Optionally, flanges are arranged on the outer circumference of the limiting ring and the outer circumference of the end of the pipeline main body, and the two flanges are locked and fixed by bolts and nuts.

[0007] Optionally, a first sealing ring is arranged on the inner wall of the limiting groove.

[0008] Optionally, a second sealing ring is arranged between the limiting ring and the pipeline main body.

[0009] Optionally, the first sealing ring and the second sealing ring are of an integral structure.

[0010] The wear-resistant mud conveying pipeline of the utility model has the following advantages:

[0011] (1) The bushing and the pipeline main body are of a split structure. The bushing can play a protective role on the pipeline main body and increase the service life of the conveying pipeline. When the bushing is damaged, the bushing can be directly replaced without affecting the pipeline main body, reducing the maintenance difficulty and cost.

[0012] (2) The steel wire layer can improve the strength of the bushing and avoid the deformation of the bushing, which affects the use.

[0013] (3) The sealing ring can improve the connection tightness of the pipe body, the bushing and the limit ring, and improve the stability of the pipe during use. DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic structural view of the present utility model. DETAILED IMPLEMENTATION MANNER

[0015] The present utility model will be further described below with reference to the accompanying drawings.

[0016] As Figure 1 shown, a wear-resistant mud conveying pipe includes a pipe body 1. A bushing is arranged inside the pipe body 1. The outer side of the bushing is attached to the inner wall of the pipe body 1. The length of the bushing is cut according to the length of the pipe body 1, and the length of the bushing should be slightly greater than the length of the pipe body 1. A wear-resistant layer 2 is arranged inside the bushing. The wear-resistant layer 2 can reduce the damage to the pipe body 1 during mud conveying. A steel wire layer 3 is arranged outside the wear-resistant layer 2. The steel wire layer 3 is used to improve the strength of the bushing and prevent the bushing from deforming and affecting normal use. Limit rings 4 are arranged at both ends of the bushing. The inner diameter of the limit ring 4 is the same as the inner diameter of the bushing. A limit groove matching the bushing is opened on the inner side of the limit ring 4. A first sealing ring 5 is arranged on the inner wall of the limit groove. The end of the bushing is arranged in the limit groove, and the connection tightness is ensured through the first sealing ring 5. Flanges 6 are arranged on the outer periphery of the limit ring 4 and the outer periphery of the end of the pipe body 1. The two flanges 6 are locked and fixed through bolts 7 and nuts 8. The bolts 7 can pull the limit rings 4 at both ends towards the pipe body 1 to improve the connection tightness of the limit ring 4, the bushing and the pipe body 1. And a second sealing ring 9 is arranged in the gap between the limit ring 4 and the pipe body 1 to further improve the connection tightness. The first sealing ring 5 and the second sealing ring 9 can also be made into an integral structure for the convenience of installing the sealing ring.

[0017] The bushing and the pipe body 1 are arranged as a split structure. The bushing can protect the pipe body 1, reduce the damage to the pipe body 1 during mud conveying, and improve the service life of the conveying pipe. When the bushing is damaged, the bushing can be directly replaced without affecting the application of the pipe body 1, reducing the difficulty and cost of maintenance.

[0018] The embodiments described above are only some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
