Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically a high-efficiency anti-caking fertilizer granulation device. Background Technology

[0002] In the process of processing granular fertilizers, fertilizer granulation towers are required.

[0003] A search of Chinese patent CN213913633U reveals a high-efficiency fertilizer granulation tower. This tower, through the coordinated use of a tower body, granulator, stirring rod, water spray holes, annular pipe, rotating rod, opening, second hopper, vibrating motor, first hopper, sieve plate, guide cover, rubber pad, driving bevel gear, motor, driven bevel gear, and water inlet valve, solves the problems of uneven fertilizer composition after granulation, lack of automatic cleaning function, and damage to granulated fertilizer due to direct impact with hard objects during descent. This high-efficiency fertilizer granulation tower offers advantages such as uniform granulation composition, automatic cleaning function, and prevention of excessive breakage of granulated fertilizer, making it worthy of promotion.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. It does not have a premixing device and directly feeds the fertilizer into the granulator for stirring. The fertilizer in the granulator is prone to stratification and clumping. In addition, the spraying structure cannot rotate, the water mist spray is not uniform and the cleaning effect is poor, which affects the efficient cleaning of the fertilizer granulation tower and reduces the fertilizer production granulation efficiency.

[0015] Firstly, this utility model is equipped with a tower body, a premixing cylinder, stirring blades, a conveying pipe, a water inlet pan, and a spray pan. The fertilizer solution at the bottom of the premixing cylinder enters the conveying pipe through an inclined pipe, is then conveyed to the top by the conveying blades, and finally returns to the top of the premixing cylinder through a return pipe. This ensures that the fertilizer solution inside the premixing cylinder is evenly mixed and prevents clumping. After that, the solenoid valve opens, and the fertilizer solution enters the granulator for uniform granulation. During cleaning, clean water enters the water inlet pan through the water inlet pipe, and then enters the spray pan through the connecting pipe. The water is sprayed out through the nozzles for cleaning. While the rotating rod drives the stirring blades to assist in cleaning, the rotating rod also drives the spray pan to rotate. The nozzles rotate accordingly to spray water mist more evenly to clean the premixing cylinder, ensuring efficient granulation of fertilizer in the subsequent process. Fertilizer first enters the premixing cylinder for premixing. The conveying pipe ensures that the fertilizer is easily and evenly mixed and does not clump. The rotating spray structure makes the cleaning of the premixing cylinder more efficient and uniform, ensuring efficient granulation of fertilizer and improving the granulation efficiency of fertilizer production.

[0016] Secondly, this utility model is equipped with a vibrating motor, a screen plate, a transmission rod, and an inclined guide plate. The vibrating motor at the bottom of the tower drives the screen plate to vibrate, which assists in the feeding of the fertilizer to be granulated. The transmission rod and the inclined guide plate guide the fertilizer to the far left of the screen plate for screening, which improves the screening effect of the fertilizer and enhances the practicality of the fertilizer granulation device.
