A pyrolysis device for producing active magnesium oxide from flotation tailings

Abstract

The utility model discloses a pyrolysis device of active magnesium oxide is prepared to flotation tailings, and cyclone preheater is connected with pyrolysis reaction system through first connecting pipe, and one end of first connecting pipe is fixedly installed on cyclone preheater, and the other end of first connecting pipe is installed on pyrolysis reaction system through bearing, and pyrolysis reaction system includes pyrolysis furnace, and pyrolysis furnace is installed on base through underframe, and pyrolysis furnace is set up obliquely, and pyrolysis furnace can rotate freely on underframe, and the inner wall of pyrolysis furnace is provided with anti -adhesion lining, has high wear resistance, erosion resistance and lower surface energy, reduces material adhesion, and strip or dentiform convex is arranged along the circumferential and axial interval of furnace body inner wall, and its effect is that when furnace body rotates, material is constantly taken up and scattered, and the contact area of material and hot flue gas is increased, and heat and mass transfer are strengthened, and simultaneously, the convex rib has shearing and crushing effect to material, can effectively break the soft briquettes formed initially, and prevents large block adhesion.
