Problems solved by technology

During the service period, the pipeline may be slightly deformed due to welding process, thermal deformation, radiation aging and other reasons. If the fuel ball is broken, there may be bridges and jams between the fuel ball and the broken pieces in the deformed pipeline. Dredging may affect the efficiency of the reactor

Embodiment 1

[0064] See Figure 7 , which shows the principle diagram of the pipe dredging system described in this embodiment.

[0065] The pipeline dredging system includes the aforementioned pipeline dredging device 10 , and also includes a medium conveying device 20 , a driving device 50 and a clutch device 60 . The medium interface 11 of the housing 1 communicates with the medium delivery device 20, and an air compressor that provides air as the working medium can be selected to input the gas that can act on the flexible sleeve 2 to provide a good gas-driven working pressure; for example but not limited to Membrane presses to provide cleaner gas or isolation atmospheres.

[0066] Wherein, the power output end of the driving device 50 is connected to the casing winding shaft through transmission to provide the driving force for the flexible casing to be wound on the casing winding shaft; a clutch device 60 is arranged between the two to switch between the disengagement drive and the e...

Embodiment 2

[0075] Compared with Embodiment 1, the difference of the pipeline dredging system described in this solution is that: the third nozzle 73 ′ of the three-way connector 70 ′ extends along the direction forming an obtuse angle with the section of the pipeline 30 to be dredged. See Figure 8 , which shows the principle diagram of the pipe dredging system described in this embodiment. In order to clearly show the difference and connection between the two, the same components or structures are shown with the same symbols in the figures.

[0076] In this solution, the first nozzle 71 ′ and the second nozzle 72 ′ of the tee connector 70 ′ are placed on the pipeline 30 to be dredged, specifically located on the upstream side of the pipeline section to be dredged. As shown in the figure, the third nozzle 73' is formed along the direction extending at an obtuse angle with the pipe section to be dredged 30, that is, the extension direction of the third nozzle 73' is the same as the pipe ...

Abstract

The invention discloses a pipeline dredging device and system. The pipeline dredging device comprises a shell and a flexible sleeve, wherein the shell is provided with a medium port communicating with an inner cavity of the shell and a dredging port used for being connected with a pipeline to be dredged; the flexible sleeve is arranged in the shell, the circumferential edge of a first end of the flexible sleeve is in sealing connection with the dredging port in the circumferential direction, and a pipe opening of the second end of the flexible sleeve is closed and connected with a body of the shell; and the flexible sleeve has a preset length and is configured as follows: when a medium entering the inner cavity of the shell from the medium port acts on the flexible sleeve, the body of the flexible sleeve can extend into the pipeline to be dredged from the dredging port in a sleeved manner. By means of the scheme, the pipeline dredging device and system has better operability on the basis of solving the problem of pipeline blockage.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging, in particular to a pipeline dredging device and system. Background technique [0002] With the development of modern technology and the surge in demand for energy and materials, process industry systems are becoming more and more complex. Taking the fields of petroleum, chemical industry and nuclear power as examples, the industrial pipelines used to transport fluids, powders and solids show the characteristics of gradually increasing outlet diameter, gradually increasing pressure, and gradually increasing transportation distance. In engineering practice, accidents caused by pipeline blockage Or outages occur from time to time. [0003] In particular, the ball transportation pipeline of the high temperature gas-cooled reactor nuclear power plant fuel loading and unloading system, which works in a high-level environment, is mainly used to transfer and transport incompletely burned fuel ...
