Abstract
The invention discloses a humus acid nitrogen fertilizer granulating device and a method thereof. The humus acid nitrogen fertilizer granulating device comprises a storage tank, a liquid ejector, a buffering filter and a granulator which are connected through a pipeline in sequence. A material input port is formed in the liquid ejector and connected with a material hopper through a pipeline. The liquid ejectors eject the urine mixed material adsorbing humus acid and other solid materials into the buffering filter along a tangent line with the ultrasonic speed, stirring, mixing, filtering and foam separating are carried out in the buffering filter, and then the urine mixed material is conveyed to the granulator to be granulated in a high tower mode. The staying time of urine, humus acid and other solid materials in the pipelines is shortened, and the amount of generated biuret is reduced. The urine, humus acid and other solid materials are prevented from blocking the pipelines and equipment, and long-period stable running of a granulating device system is achieved.
