Description

TECHNICAL FIELD

[0001] The utility model relates to compound fertilizer production and processing technical field, concretely is a kind of reaction kettle for compound fertilizer production. BACKGROUND

[0002] Compound fertilizer production and processing refers to the process of mixing different types of nutrient elements (such as nitrogen, phosphorus, potassium) and possible trace elements in a certain proportion and processing them into granular or powdery fertilizer. This fertilizer can provide the main nutrient elements required for crop growth, thereby improving soil fertility and crop yield.

[0003] For example, Chinese patent CN117753347B discloses a reaction kettle for compound fertilizer production;

[0004] The technical solution described in this scheme sets up a stirring mechanism. The first gear drives the first inner tooth ring to rotate, causing the scraper to move in a circular motion and clean the compound fertilizer raw materials attached to the inner wall of the kettle body. This prevents the inner wall of the kettle body from being corroded by the long-term attachment of compound fertilizer raw materials. The second mounting ring rotates with the stirring shaft, causing the stirring blades on the second mounting ring to stir the compound fertilizer raw materials in the kettle body in a forward direction. At the same time, the rotation of the stirring shaft also drives the second inner tooth ring to rotate, causing the stirring blades on the first mounting ring to stir the compound fertilizer raw materials in the kettle body in a reverse direction. This allows the compound fertilizer raw materials to be mixed more uniformly, improving the reaction rate and quality of the compound fertilizer raw materials.

[0005] However, the scraper in this technical solution can only scrape off the raw materials attached to the inner wall of the kettle body, and cannot scrape off the raw materials attached to the inner bottom of the kettle body, which is inconvenient to use.
