Description

Technical Field

[0001] The utility model belongs to the technical field of granular urea raw material processing, in particular to a granular urea raw material conveying device. Background Art

[0002] Urea is a high-nitrogen fertilizer, containing approximately 46% nitrogen, making it the highest-nitrogen solid nitrogen fertilizer currently available. Once applied to the soil, urease gradually hydrolyzes urea into ammonium nitrogen, which is absorbed and utilized by plant roots, promoting plant growth and development. In urea production plants, conveying equipment transports granular urea from the prilling tower to the packaging workshop, enabling continuous production. During this process, friction occurs between the granular urea and components of the conveying equipment. This friction can cause tiny particles on the surface of the granular urea to fall off, forming dust. Existing conveying equipment can meet basic conveying needs, but the dust generated can cause environmental pollution, impact human health, and increase equipment wear.

[0003] A search of Chinese patent documents (authorization publication number CN221310516U) reveals that the utility model discloses a granular urea raw material pumping device, comprising a urea raw material storage tank, a raw material stirring device rotatably mounted within the tank, a filtering device mounted on the inner wall of the tank, and a conveying mechanism mounted at one end of the tank. The raw material stirring device comprises a mixing assembly that thoroughly stirs the granular urea raw material stored within the tank, preventing the granules from sticking together. An anti-precipitation assembly scrapes off any unstirred granular urea at the bottom of the tank, removing crystals on the bottom and preventing blockage of the pump outlet at the bottom that could affect the feeding of the granular urea. A filtering device is provided, which filters impurities from the stored granular urea through a filter screen. A second motor drives an eccentric wheel to rotate, vibrating the filter screen and accelerating the filtration process. While the device can meet basic conveying requirements, the dust generated can cause environmental pollution, affect human health, and increase equipment wear. Utility Model Content
