The impeller assembly provided in the present application includes: a stirring impeller, wherein the stirring impeller includes a rotating shaft and blades arranged around the rotating shaft along the circumferential direction; a surrounding plate, wherein the surrounding plate is arranged around the outer periphery of the stirring impeller, and the surrounding plate is provided with a plurality of discharge holes, the surrounding plate further includes a plurality of dispersing teeth, the plurality of dispersing teeth are arranged facing a rotation direction of the blades, and the plurality of dispersing teeth are distributed around the periphery of the plurality of discharge holes.

Abstract: A mixing and dispersing apparatus includes a tank body, a stirring part, a dispersing part, and a driving part. The tank body has an accommodating cavity configured to accommodate materials. The stirring part is disposed in the accommodating cavity and configured to mix the materials in the accommodating cavity. The dispersing part is disposed in the accommodating cavity and includes a first cylinder and a second cylinder. The first cylinder has a first cavity in communication with the accommodating cavity, the second cylinder is located in the first cavity, and the second cylinder has a second cavity in communication with the accommodating cavity. The driving part is connected to the stirring part and the dispersing part. The materials mixed in the accommodating cavity flow into the second cavity and flow out after being dispersed in the dispersing part.

Abstract: Disclosed herein is a method for preparing coal-based, briquetted activated carbon. The method includes subjecting raw coal to a briquetting process, pulverizing the briquettes into particles, and performing carbonization and activation to obtain activated carbon. The briquetting process includes pulverizing raw coal to produce a feed, feeding the feed into a feed bin for degassing, adjusting the temperature and the water content of the feed in the feed bin, and feeding the feed in the feed bin into a briquetting apparatus for briquetting to form coal briquettes. The raw coal briquetting process of the preparation method is suited to a wide variety of coal, including non-caking coal. The preparation method yields a coal briquette product with a strength greater than 89% without any binder, which is beneficial to improve the strength and the like of activated carbon.
