Embodiment 1

[0040] Such as figure 1 As shown, the present invention provides a fault location system for pneumatic sample delivery pipelines. The system is composed of three subsystems, including a pressure wave generation system 1, a pipeline access system 2 and a measurement and analysis system 3. The pipeline access system 2 is used for After being connected to the pneumatic sample delivery pipeline 4, the system can detect and locate the position of the obstacle 41 in the pneumatic sample delivery pipeline 4 and the type of the obstacle. The output end of the pressure wave generation system 1 is connected to the input end of the pipeline access system 2, and the measurement and analysis system 3 can be connected to the output end of the pressure wave generation system 1 or to the wall of the pipeline access system 2 , to measure the pressure wave signal inside the pipeline.

[0041] The pressure wave generation system 1 in this scheme is used to generate pressure waves with a certain...

Embodiment 2

[0044] Such as figure 1 As shown, this embodiment provides a fault location system for pneumatic sample delivery pipelines. In this embodiment, the pipeline access system 2 includes a three-way pipe 21, and the three-way pipe 21 includes a main line pipeline 211 and a branch line pipeline 212. The branch line pipeline 212 One end of the main line pipeline 211 is connected to the middle position, after the connection, the main line pipeline 221 and the branch line pipeline 212 run through, the other end of the branch line pipeline 212 is used as the input end of the pipeline access system 2, and one or both ends of the main line pipeline 211 are used as the pipeline access system 2 output terminals. The installation position of the pneumatic sample delivery pipeline fault location system, that is, the installation position of the pipeline access system 2 in the pneumatic sample delivery pipeline 4, can be any point within the range of the pneumatic sample delivery pipeline 4, w...

Embodiment 3

[0046] Such as figure 1 As shown, the basic structure of this embodiment is the same as that of Embodiment 2. On the basis of Embodiment 2, the two ends of the main line pipeline 211 are respectively provided with a main line valve 23. The main line valve 23 is preferably a ball valve, and the ball valve in the pipeline can reduce the impact on the pipeline. Effect of Shipping Samples. When the pneumatic sample delivery pipeline 4 is working, the main line valve 23 remains open. The open main line valve 23 does not affect the normal transmission of the pneumatic sample delivery pipeline 4 to the sample box. When the pneumatic sample delivery pipeline 4 breaks down, it can pass Control the switch of the main line valve 23 at both ends of the main line pipeline 211, select the pipeline on one side to detect, and when one of the main line valves 23 is closed, the pressure wave can all move in the direction of the other open main line valve 23. The working process of the system i...

Abstract

The invention discloses a pneumatic sample conveying pipeline fault positioning system and method, and belongs to the field of pneumatic sample conveying pipeline fault point positioning detection. The system specifically comprises a pressure wave generation system, a pipeline access system and a measurement and analysis system; the pipeline access system is used for being connected with a pneumatic sample conveying pipeline; the output end of the pressure wave generation system is firstly connected with the input end of the measurement analysis system and then connected with the input end ofthe pipeline access system. According to the technical scheme, an existing pipeline can be connected only by adding a three-way pipe into an original pneumatic sample conveying system, the original pipeline is slightly changed, and the implementation cost is low.

Description

technical field [0001] The invention belongs to the field of fault location and detection of a pneumatic sample delivery pipeline, and in particular relates to a fault location system and a location method of a pneumatic sample delivery pipeline. Background technique [0002] In metallurgy, cement, casting and other industries, in order to ensure the stability of product quality, it is required to quickly sample, send samples, analyze and test and feedback the results in time during the process. For this reason, the factory often uses a pneumatic sample delivery system to quickly transfer samples between the production workshop and the laboratory. In principle, the pneumatic sample delivery system uses compressed air as power to push the sample box to run in a special sample delivery pipeline. In terms of structural composition, the pneumatic sample delivery system usually includes electric control cabinets, transceivers, gas storage tanks, photoelectric monitoring devices,...
