Problems solved by technology
[0003] However, due to technical limitations, there has been no suitable equipment and method for directly mixing and heating urea and humic acid and other solid materials. The reason is that the melting point of urea is 132.7°C. After adding humic acid and other solid materials, it will absorb humic acid and other solids. The urine viscosity of the material will increase. In order to reduce its viscosity, the temperature must be increased. The higher the temperature, the more biuret will be formed, and the humic acid is easy to decompose when the temperature is high.
Biuret is an indicator for strict control of urea fertilizers. In order to reduce the content of biuret, the granulation temperature must be lowered, so that the viscosity of urine that absorbs solid materials such as humic acid will increase, and urine and humic acid and other solids will The longer the material stays in the pipeline, and it is easy to block the pipeline and equipment, which brings difficulties to the operation of granulation equipment

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.
Description
technical field [0001] The invention relates to nitrogen fertilizer granulation equipment and a method thereof, in particular to a humic acid nitrogen fertilizer granulation equipment and a method thereof. Background technique [0002] Humic acid has a synergistic effect on chemical fertilizers, especially urea. The reason for the synergistic effect comes from the inhibitory effect of humic acid on soil urease. Humic acid can not only prevent the rapid decomposition of urea, but also have a synergistic effect on urea, which is beneficial to crop growth and development. It can improve the stress resistance of crops, improve the quality of crop fruits, reduce the opening degree of leaf stomata, reduce the drought resistance and water saving performance of water transpiration, and the slow release of pesticides, etc., thus effectively improving the utilization value of urea. [0003] However, due to technical limitations, there has been no suitable equipment and method for dire...
