Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the embodiment 1, in order to solve the problems that the air flow has high flowing speed in the pipeline, the inner wall of the pipeline is impacted when the air flow passes through the corner of the pipeline, particularly, the air flow drives granular materials or powder to impact the inner wall of the pipeline, the pipeline is vibrated, the inner wall of the pipeline is severely worn, and the corner of the pipeline is most prone to grinding and leakage; the marine system pipeline with the vibration reduction structure as shown in the figures 1-11 comprises an outer pneumatic flow pipeline 13 and an inner pneumatic flow pipeline, wherein the inner pneumatic flow pipeline is bent, the outer pneumatic flow pipeline 13 is sleeved outside the inner pneumatic flow pipeline as an outer protecting sleeve of the inner pneumatic flow pipeline, the inner pneumatic flow pipeline is communicated between a first pipeline 11 and a second pipeline 12, and air flow drives materials to flow from the first pipeline 11, the inner pneumatic flow pipeline and the second pipeline 12 in sequence; the spring 141 is fixedly welded at the outer ring of the inner pneumatic flow pipeline, one end of the spring 141, which is far away from the outer ring of the inner pneumatic flow pipeline, is movably attached to the inner wall of the outer pneumatic flow pipeline 13, the inner pneumatic flow pipeline comprises an inner pneumatic flow pipeline splice plate 14 and an elastic connection structure, an annular air cavity is formed between the outer ring of the inner pneumatic flow pipeline and the inner ring of the outer pneumatic flow pipeline 13, at least four inner pneumatic flow pipeline splice plates 14 are arranged, a plurality of inner pneumatic flow pipeline splice plates 14 are spliced to form a pipeline shape, the elastic connection structure corresponds to the plurality of inner pneumatic flow pipeline splice plates 14 one by one, the elastic connection structure is connected between the two adjacent inner pneumatic flow pipeline splice plates 14, the elastic connection structure has certain elasticity, when air flow drives materials to enter the inner pneumatic flow pipeline, the air flow drives the materials to push the inner pneumatic flow pipeline splice plates 14 to compress the spring 141, so that the buffering purpose is achieved, the impact force of the air flow and the materials to the inner pneumatic flow pipeline is reduced, the vibration of the whole pipeline is reduced, and the abrasion problem of the inner pneumatic flow pipeline is reduced.
It should be noted that, because the pressure of the air flow driving the material passing through the inner pneumatic flow pipeline is not constant, the impact force of the air flow and the material on the inner pneumatic flow pipeline splice plate 14 is unstable, so that the spring 141 has two states of being compressed and rebounded, and the inner pneumatic flow pipeline splice plate 14 continuously oscillates, and the oscillation of the inner pneumatic flow pipeline splice plate 14 is utilized to counteract the impact force of the air flow and the material, so that the overall oscillation of the pipeline is reduced, and the force of the air flow and the material impacting the inner pneumatic flow pipeline is weakened when the inner pneumatic flow pipeline splice plate 14 itself oscillates.

When the material driven by the air flow is particulate matter, the spring 141 with proper elasticity is used, so that the maximum thrust generated by the air flow with the animal material flow can only push the spring 141 to compress to a certain extent, and the width of a gap formed when two adjacent first rubber strips 143 are mutually far away is smaller than the minimum diameter of the particulate matter, thereby avoiding the particulate matter from entering the gap between the two first rubber strips 143 and leaking between the inner ring of the outer pneumatic flow pipeline 13 and the outer ring of the inner pneumatic flow pipeline; based on intermittent opening and closing between the two first rubber strips 143, impurities or dust doped in the particulate matters can enter between the inner ring of the outer pneumatic flow pipeline 13 and the outer ring of the inner pneumatic flow pipeline through gaps, so that the purpose of dust removal and screening of the particulate matters in the flow process is achieved.
