Device and method for preparing activated aluminum oxide porous material

The invention relates to the technical field of fluorine removal, in particular to a preparation device and method of an activated aluminum oxide porous material. The invention provides the preparation device and method of the activated aluminum oxide porous material, which can be used for conveniently removing or collecting the prepared product in the preparation mixing barrel and improving the preparation efficiency and the operation convenience. The preparation device comprises a bottom plate, pneumatic sliding tables and the like, and the pneumatic sliding tables are connected to the upper sides of the front portion and the rear portion of the bottom plate. The telescopic end of the hydraulic cylinder upwards jacks the hanging arm to take up the filter screen, the prepared product in the mixing barrel is guided out through the upward lifting of the filter screen, and in the lifting process of the filter screen, the elastic scraping plate is in contact with the inner wall of the mixing barrel to scrape off
