Catalyst slurry preparation device

The utility model relates to the technical field of catalyst slurry, in particular to a catalyst slurry preparation device which comprises a stirring barrel and a bottom plate, a scraper is attached to the inner cavity wall of the stirring barrel, a limiting rod is fixedly connected to the middle of the lower end of the side, close to the axis of the stirring barrel, of the scraper, and a dispersing disc is slidably connected to the lower end of the limiting rod. A second rotating shaft is fixedly connected to the middle of the upper end of the dispersing disc, the end, away from the threaded sleeve, of the first connecting rod is rotationally connected with the scraping plates through pin shafts, and the threaded sleeve slides up and down to drive the first connecting rod to rotate, so that the scraping plates are close to or away from each other at the same time. The condition that more catalyst slurry is attached to the contact surface of the scraping plate and the mixing drum and is difficult to clean is
