External blue spraying structure and granulation device

The utility model discloses an external blue spraying structure and a granulation device. The outer blue spraying structure comprises an outer blue spraying body used for containing slurry and an annular plate arranged on the periphery of the outer blue spraying body in a surrounding mode. A cutting plate is arranged on the edge, away from the outer blue spraying body, of the annular plate. Holes for spraying slurry are formed in the side face of the outer blue spraying body. By arranging an annular plate and a cutting plate, holes can be formed to be larger in the granulation process, and further a spiral cutter is arranged, so that the downward pressure of slurry in external spraying blue can be increased, and blockage can be further prevented. 本实用新型公开了一种外喷蓝结构及造粒装置；所述的外喷蓝结构包括：用于容纳浆料的外喷蓝本体和环绕设置在外喷蓝本体外围的环形板；所述环形板远离外喷蓝本体的边上设置有切割板；所述外喷蓝本体的侧面上设置有供浆料喷出的孔洞。通过设置了环形板和切割板，使得造粒过程中孔洞可以设置得更大，进一步的设置了螺旋刀，能够增加外喷蓝中的浆料的下压力，能够进一步的防止堵塞。
