Background technique
Filling pipeline is generally made using high-strength steel pipe, and steel pipe is nontransparent visual, therefore is difficult to obtain in filling pipeline
Slurry status information.If precipitating isolation, not full packages, phenomena such as local concentration is excessive, meeting occur in filling pipeline for filling slurry
Lead to plugging, pipe explosion accident.Therefore in time grasp filling slurry whether occur in filling pipeline precipitating isolation, whether full packages with
And the information such as pulp density in pipeline, it is of great significance to the stabilization of maintenance filling system.Currently, mine generally uses pipeline
Segmentation installs pressure gauge and concentration meter to monitor filling slurry flow regime in pipeline, but this method can only obtain a certain pipe
Slurry status information in section, and need largely to lay pressure gauge and concentration meter in pipeline.
It there is no a kind of device to may be implemented to carry out any one place's filling pipeline accurate lossless monitoring at present, filled
Slurry whether occur in filling pipeline precipitating isolation, whether information such as pulp density in full packages and pipeline.Ultrasonic wave is not
It is different with the speed of Propagation, in filling pipeline when slurry state difference, ultrasonic velocity on filling pipeline different directions
Different distribution characters can be presented, therefore can use the next anti-pusher slurry of ultrasonic velocity distribution on filling pipeline different directions and exist
Status information in filling pipeline.
Summary of the invention
Technical problems to be solved needed for the present invention are to provide slurry state monitoring apparatus in a kind of filling pipeline and its make
