Description

Technical Field

[0001] This utility model relates to the field of urea particle processing technology, specifically a rotary drum granulation device for preparing large-particle urea particles. Background Technology

[0002] Large-particle urea granules typically refer to urea particles with a diameter between 2-8 mm. Compared to traditional urea production using tower granulation or spray granulation technologies, these urea particles are smaller (usually less than 2 mm in diameter), have insufficient strength, and are prone to absorbing moisture and clumping during transportation and storage, affecting their effectiveness. Furthermore, small-particle urea dissolves quickly, leading to nitrogen loss through water after application to the soil, resulting in reduced fertilizer utilization. For example, the nitrogen loss rate of traditional urea in the soil is as high as 30%-65%, causing resource waste and environmental pollution. Large-particle urea (2-8 mm in diameter) dissolves slowly, releasing nitrogen over a longer period, thus reducing nitrogen loss. For instance, applying large-particle urea to paddy fields can increase fertilizer efficiency by more than 10% and nitrogen utilization by 15%-30%. Large-particle urea has high strength and produces less dust, making it suitable for long-distance bulk transportation and storage, reducing packaging and transportation costs, and minimizing losses during transport.

[0003] The existing urea granulation process requires the use of a rotary drum granulator. This device mixes materials and additives inside the drum, and the rotation of the drum causes the materials to agglomerate into granules under liquid conditions. The process is short, simple to operate, and easy to automate. It can also adapt to different formulations and raw materials. By adjusting process parameters (such as temperature, rotation speed, and spray volume), various specifications of urea granules can be produced to meet diverse market demands. However, in existing rotary drum granulation devices, after granulation of the materials and additives, the granules accumulate at the bottom of the drum due to gravity. Currently, the granules are typically manually pushed out through an opening on one side of the drum by scrapers, which is cumbersome and labor-intensive.

[0004] Therefore, it is necessary to provide a new rotary drum granulation device for preparing large-particle urea particles to solve the above-mentioned technical problems. Utility Model Content
