Description

Technical Field

[0001] The utility model relates to the technical field of chemical fertilizer processing, in particular to an anti-blocking structure for a chemical fertilizer granulator. Background Technique

[0002] Chemical fertilizers, abbreviated as chemical fertilizers, are fertilizers made by chemical and physical methods and containing one or several nutrient elements required for crop growth. They have the following common characteristics: simple composition, high nutrient content; fast fertilizer efficiency, strong fertilizer strength; some fertilizers have acid-base reactions; generally do not contain organic matter and have no effect on improving soil fertility.

[0003] Chinese Patent Publication No.: (CN216964513U) This columnar chemical fertilizer granulating device is mainly provided with a machine shell. An inner groove of the machine shell is fixedly connected with a shaping cylinder. A central column is rotatably connected to the outside of the shaping cylinder close to the machine shell. A linkage tooth is fixedly connected to the lower end of the central column. A shaping column is fixedly connected to the surface of the central column. A shaping motor is fixedly connected to the lower end of the machine shell. A driving gear is fixedly connected to the output end of the shaping motor. A large gear ring is meshed with the surface of the driving gear. The inner side of the large gear ring is meshed with the linkage tooth. In this columnar chemical fertilizer granulating device, the semi-finished chemical fertilizer is extruded and shaped by the rotation of the shaping columns from small to large, making it more convenient to granulate during production and capable of changing the texture of the chemical fertilizer. The large gear ring drives the linkage gear to rotate simultaneously, so that the semi-finished chemical fertilizer can be evenly extruded, making the production of chemical fertilizer particles more uniform, achieving the effect of tight and uniform texture of chemical fertilizer particles and solving the problem of loose and uneven texture of chemical fertilizer particles.
