This rotation is then transmitted to the rotating shaft 13 via the universal joint 12. For this reason, the screw 16 installed at the lower part of the rotating shaft 13 rotates, and as a result, the guide tube 1
An upward jet is generated inside 5. Therefore, the sediment accumulated at the bottom of the storage tank 10 is sucked up from the lower end of the guide tube 15, and the sucked up sediment is diffused into the storage tank 10 from the upper end of the guide tube 15. Stirring is performed.

果を有する。"Effects of the Invention" As explained above, the present invention provides a guide tube in the upper part of the storage tank so as to be swingable in the vertical direction and in a horizontal plane, and a jet flow in the lower part of the guide tube. Since it is equipped with a jet source device to generate jet flow and a scraping device to scrape off sediment accumulated at the bottom of the storage tank, the lower part of the guide pipe is moved along the bottom of the storage tank, centering on the upper part of the guide pipe. At the same time, the scraping device scrapes off the sediment accumulated at the bottom of the storage tank, and the jet generated by the jet source device is used to suck up the scraped sediment with the guide tube. By stirring the liquid stored in the storage tank, the sediment deposited at the bottom of the storage tank can be easily and reliably sucked up through the guide pipe.
It has excellent effects of being able to stir smoothly and preventing sediment from accumulating at the bottom of the storage tank.
