Embodiment Construction

[0033] Combine below figure 2 with image 3 , the present invention is further described:

[0034] Such as figure 2 As shown, a pipeline transportation system includes a stirring tank 1, a clean water tank 5 and a feeding pump 6, the output pipeline of the stirring tank 1, the output pipeline of the clean water tank 5 and the slurry pipeline 11 at the input end of the feeding pump 6 are connected In a three-way structure, the ore delivery valve 2 is set on the output end pipeline of the mixing tank 1, the water delivery valve 3 is set on the output end pipeline of the clear water tank 5, and the feeding pump inlet valve 4 is set on the input end slurry pipeline 11. The slurry pipeline 11 at the input end of the feed pump 6 is also connected with a switching buffer device for pipeline transportation of different pressure media. Connect the switching buffer device on the slurry pipeline 11, the switching buffer device is a pulsation buffer nitrogen tank 7, and the pulsation...

Abstract

The invention relates to a switching buffer device for different pressure media in pipeline transportation and a pipeline transportation system. The switching buffer device is connected onto a slurry pipeline (11) and is a pulsation buffering nitrogen tank (7), and the pulsation buffering nitrogen tank (7) comprises a tank shell (8) and a nitrogen bag (9). When pressure of media in the slurry pipeline (11) increases, the nitrogen bag (9) is compressed, and pressure of nitrogen in the compressed nitrogen bag is increased. When pressure of media in the slurry pipeline (11) decreases, pressure accumulated in the nitrogen bag (9) is released and compensated to the media in the slurry pipeline (11). Energy compensation and buffering are achieved in switching process of the long-distance slurry pipeline by the pulsation buffering nitrogen tank, water hammer effect generated by media of different pressures is restrained and eliminated effectively, violent vibration of a slurry pipeline system is avoided, and devices of the slurry pipeline system and a feed pump and the like are protected.

Description

technical field [0001] The invention relates to a switching buffer device and a pipeline transportation system, in particular to a switching buffer system and a pipeline transportation system used in iron concentrate pipeline transportation. Background technique [0002] Long-distance iron ore concentrate pipeline transportation is an emerging and high-tech industry, and it is also a highlight of low-carbon and green economy. Long-distance slurry pipeline transportation requires slurry to be transported in batches, and some water needs to be interspersed between the upper batch and the lower batch according to the process requirements to prevent pipeline overpressure and blockage. [0003] Such as figure 1 As shown, it is the traditional transportation process diagram of the long-distance slurry pipeline, and the process description: [0004] 1. When the conveying medium of the slurry pipeline is iron ore concentrate, the mixing tank 1 will stir the slurry evenly. By openi...
