Technical Field
[0001] This utility model relates to the field of compound fertilizer technology, specifically a granulation device for compound fertilizer. Background Technology
[0002] Compound fertilizers are chemical fertilizers containing two or more of the essential nutrients nitrogen, phosphorus, and potassium. They offer advantages such as high nutrient content, fewer byproducts, and good physical properties, playing a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. However, they also have some drawbacks. For example, their nutrient ratios are always fixed, while different soils and crops require different types, quantities, and ratios of nutrients. Therefore, it is best to conduct soil testing before use to understand the soil texture and nutrient status. Additionally, it is important to combine them with single-element fertilizers to achieve better results.
[0003] When producing compound fertilizer, granulation is required. After granulation, the material needs to be transferred to a drying device. This back-and-forth transfer process results in material loss. Utility Model Content

[0013] This invention involves feeding material into the top hopper, with a corresponding sealing end plate bolted to the opening of the extrusion tank. After setting the control panel, the transmission motor rotates, causing the output end to drive the push screw. The rotating screw forces the material through the inlet into the extrusion tank, pushing it towards the opening and extruding it through the extrusion hole. Simultaneously, the scraper motor rotates, causing the output end to drive the scraper rod to rotate on the side of the sealing end plate, allowing the scraper... The material extruded from the extrusion hole is cut by the feed rod, and the cut material falls downward into the receiving hopper below. Then, it enters the supporting bottom box through the top opening. After the material particles fall onto the top surface of the guide plate and roll downward, the drying chamber at the bottom creates a high-temperature drying effect on the guide plate and the supporting bottom box. After the particles are dried and shaped, they are discharged and collected outward through the discharge pipe on the side. The integrated control structure makes it more convenient and efficient to control and use. At the same time, the integration of granulation and drying greatly improves production efficiency.
