In the above technical solution, the impeller has a plurality of scraper blades, dividing an annular space between an inner cavity of the outer casing and an outer wall of the stationary inner core into a plurality of cells.

Compared with the prior art, the invention has the beneficial effects that:

the star-shaped air locking device adopts a double-discharge-port design, can convey materials to two discharge ports respectively by changing the rotating direction of the driving motor, and has the air locking and material distributing functions.

Scrape board-like blade structure, realize both components of a whole that can function independently of impeller and static inner core, the rotatory material of carrying of impeller, static inner core is fixed, through the scraping effect of scraping board-like blade, avoids the material adhesion at casing and static inner core.

By controlling the height and the interval of the scraper blades, the adhesion amount of materials on the impeller can be effectively reduced, and the conveying efficiency is improved.

Proper gaps are reserved between the impeller and the shell and between the impeller and the static inner core, so that smooth operation and good air locking function are ensured.
