Abstract

The invention discloses a non-intervention type paster filling pipeline block monitoring device and method. The device includes an ultrasonic wave monitoring device, a PLC and a computer. An ultrasonic wave emitting probe and an ultrasonic wave receiving probe of the ultrasonic wave monitoring device are arranged on two ends of a filling pipeline to be monitored. The ultrasonic wave emitting probe is connected with the ultrasonic wave emitting device. The ultrasonic wave emitting device is connected with a single-chip microprocessor. The ultrasonic wave receiving probe is connected with an ultrasonic wave receiving device. The ultrasonic wave receiving device is connected with the single-chip microprocessor. The other end of the single-chip microprocessor is connected with the PLC and automatically controls a paster filling pump system through the PLC. According to the invention, by mounting the above device provided by the invention in the middle of the filling pipeline to be monitored, wave speeds of different positions in the ultrasonic wave pipeline can be measured. When pipeline block occurs, the wave speed difference of ultrasonic waves in front of a pipeline block position and behind the pipeline block position is distinct, so that accurate positioning of the pipeline block position is realized. According to the invention, automatic monitoring and damageless monitoring of the paster filling pipeline block is realized.

Description

technical field [0001] The invention relates to a non-intervention type paste filling pipeline plugging monitoring device and method, in particular to a long-distance paste filling pipeline plugging monitoring device and method for mine filling mining, which belongs to the paste filling pipeline transportation technology field. Background technique [0002] my country's "three under" coal pressure is huge. In order to effectively exploit the "three under" coal resources and extend the service life of the mine, paste filling mining is one of the effective methods to liberate the "three under" coal pressure. The paste is filled on the ground and the raw materials are mixed, and then rely on pipelines to realize efficient and continuous transportation to the goaf. During the transportation process, the pipeline is easily blocked due to impurities entering the pipeline, segregation and precipitation of the slurry, and insufficient pumping pressure. Pipe plugging not only affec...
