Abstract
The utility model discloses a coal dust conveying pipeline. The coal dust conveying pipeline comprises a horizontal pipeline and a vertical pipeline, wherein an inclined angle is formed between the horizontal pipeline and the vertical pipeline; a buffer device is arranged in the connecting position of the horizontal pipeline and the vertical pipeline, and the connecting position is provided with a connecting sleeve; the horizontal pipeline, the vertical pipeline and the buffer device are respectively fixed with the connecting sleeve through bolts; the horizontal pipeline and the vertical pipeline are respectively inserted in the buffer device; the buffer device comprises a barrel body and cover plates arranged on two end surfaces; the horizontal pipeline and the vertical pipeline are respectively connected with the barrel body of the buffer device; the buffer device is spherical and hollow; the horizontal pipeline and the vertical pipeline are mutually perpendicular; the buffer device is thicker than the pipelines, and a wear-resisting material layer is arranged on the inner wall of the buffer device. The coal dust conveying pipeline is simple in structure and practical in function, can greatly prolong service life of the turning pipelines, is convenient and fast to replace and greatly improves working efficiency.
Description
Technical field
The utility model relates to a kind of power transportation pipe.
Background technology
Coal dust conveying at present is mainly that wind send; in the pipeline corner; coal dust can clash into inner-walls of duct; cause the pipeline corner to damage very soon, need in the time of maintenance to shut down, with the whole replacing of the bend pipe of corner; perhaps the damage pipeline with the corner blocks; then connect new pipeline and with old pipeline welding, waste time and energy, inefficiency.
The utility model content
The utility model provides a kind of power transportation pipe, and is simple in structure, is convenient for changing, and increases service life.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of power transportation pipe, include horizontal pipe and vertical pipeline that angle is arranged, at horizontal pipe and vertical pipeline junction, shock absorber is set, and the junction arranges adapter sleeve, horizontal pipe, vertical pipeline, shock absorber are bolted with adapter sleeve respectively, and horizontal pipe, vertical pipeline insert respectively the shock absorber setting.
Shock absorber comprises the cover plate that cylindrical shell and both ends of the surface arrange, and horizontal pipe, vertical pipeline are connected with the cylindrical shell face of shock absorber respectively.
Shock absorber is spherical hollow.
Horizontal pipe is mutually vertical with vertical pipeline.
The thickness of shock absorber is greater than duct thickness, and the shock absorber inwall is provided with wear-resistant material layer.
The utility model is simple in structure, practical function, can greatly increase the service life of corner pipeline, and changes convenient, fastly, greatly increases work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of power transportation pipe, include horizontal pipe 2 and vertical pipeline 3 that angle is arranged, at horizontal pipe 2 and vertical pipeline 3 junctions, shock absorber 1 is set, and the junction arranges adapter sleeve 4, horizontal pipe 2, vertical pipeline 3, shock absorber 1 are fixing by bolt 5 with adapter sleeve 4 respectively, and horizontal pipe 2, VERTICAL TUBE 3 roads insert respectively shock absorber 1 and arrange.Shock absorber 1 comprises the cover plate that cylindrical shell and both ends of the surface arrange, and horizontal pipe 2, vertical pipeline 3 are connected with the cylindrical shell face of shock absorber 1 respectively.Perhaps shock absorber 1 is the spherical hollow structure.Horizontal pipe 2 is mutually vertical with vertical pipeline 3.The thickness of shock absorber 1 is greater than duct thickness, and shock absorber 1 inwall is provided with wear-resistant material layer.
The coal dust that wind send in the pipeline corner in the interior collision of shock absorber 1, turn to, greatly reduced the damage to pipeline, increased the service life of pipeline.
