Description

Technical Field

[0002] Usually, the production of gypsum powder usually requires drying the gypsum ore through a hot air dryer. A hot air dryer is a device that uses hot air as a drying medium. It can evaporate the moisture in the gypsum ore and convert it into dry gypsum powder. At the same time, the hot air dryer introduces high-temperature hot air into the drying chamber through the air supply system. The gypsum ore is transported into the drying chamber. Under the action of the high-temperature hot air, the moisture in the gypsum ore evaporates quickly and is discharged from the drying chamber through the hot air, thereby achieving the drying of the gypsum powder.

The utility model is provided with an interception net, an extrusion plate, a threaded rod and a drying mechanism. The dried gypsum powder falls onto the interception net, and the powdered gypsum powder directly falls out to the bottom of the box through the through holes of the interception net, while the block gypsum powder is intercepted on the interception net. The rotation of the threaded rod causes the extrusion plate to move in the direction of approaching each other, and the block gypsum powder is squeezed into powder, so that the block gypsum powder can be intercepted by the interception net just fallen out, so as to prevent the block gypsum powder from falling directly to the bottom of the box and blocking the discharge port.
