Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer processing, in particular to a drying device for fertilizer production. Background Art

[0002] Fertilizer drying can effectively reduce the moisture content in fertilizer, thereby improving the quality and efficiency of fertilizer. The reduction of moisture content helps to stabilize fertilizer during storage and transportation, and reduces fertilizer mildew and nutrient loss caused by moisture. At the same time, the strength of fertilizer particles increases after drying, reducing nutrient loss caused by particle breakage during storage and transportation, thereby extending the storage life of fertilizer. Fertilizer drying is not only important for improving fertilizer quality, extending storage life, reducing environmental pollution and saving energy costs, but also for promoting sustainable agricultural development and adapting to the needs of different types of fertilizers.

[0003] The publication number is "CN108645189A" and the name is "A Dryer for Compound Fertilizer Production". It discloses a drying device for fertilizer production. It mainly sets up structures such as a feed port to allow an arc-shaped scraper to push the fertilizer quickly into the heating plate in the processing bin to improve work efficiency. This drying method cannot allow the fertilizer to evenly contact the heat source, which may easily lead to the fertilizer not being fully dried. In the subsequent transportation process, the fertilizer is prone to caking and mold. Utility Model Content

[0004] The utility model aims to provide a drying device for fertilizer production. Through the action of a stirring rod, hot air enters the interior of a drying box from the bottom of the drying box. The hot air contacts the fertilizer in the drying box more comprehensively from bottom to top. At the same time, when the fertilizer in the drying box is dried with hot air, the stirring rod stirs the fertilizer to ensure that all parts of the fertilizer can be evenly contacted with the heat source, thereby avoiding the situation that the surface of the fertilizer dries too quickly while the interior is still wet, ensuring that the moisture content of the entire fertilizer is evenly reduced, and solving the problem that the existing drying method cannot allow the fertilizer to be evenly contacted with the heat source, which easily leads to the fertilizer not being fully dried. In the subsequent transportation process, the fertilizer is prone to problems such as agglomeration and mildew.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0045] Specifically, a plurality of heating wires 18 are fixed inside the heating box 16, and the hot air pipe 15 is an annular hollow pipe.

[0046] The operation process of this embodiment is as follows: when the device is in use, the fertilizer to be dried is poured into the drying box 1 through the feed port 9, and the first motor 4, the second motor 302, the blower pump 17 and the heating wire 18 are turned on. The output shaft of the first motor 4 drives the rotating rod 5 at one end thereof to rotate. During the rotation, the plurality of stirring rods 6 on the outer ring of the rotating rod 5 also stir the fertilizer in the drying box 1. At the same time, the blower pump 17 draws cold air into the heating box 16. After the heating wire 18 in the heating box 16 heats the air, it is sent into the drying tube 10 through the hot air pipe 15. The hot air in the drying tube 10 stirs the fertilizer in the drying box 1. The fertilizer is heated. During this process, the filter screen 14 at one end of the drying tube 10 can prevent the fertilizer in the drying box 1 from entering the hot air pipe 15 through the drying tube 10, thereby preventing the drying tube 10 from being blocked. At the same time, the hot air enters the interior of the drying box 1 from the bottom of the drying box 1. The hot air comes from bottom to top, and can contact the fertilizer in the drying box 1 more comprehensively. At the same time, when the fertilizer in the drying box 1 is dried by hot air, the stirring rod 6 stirs the fertilizer to ensure that all parts of the fertilizer can evenly contact the heat source, thereby avoiding the situation where the surface of the fertilizer dries too quickly while the inside is still wet, thereby ensuring that the moisture content of the entire fertilizer is evenly reduced.

[0051] The operation process of this embodiment is as follows: when the output shaft of the first motor 4 stirs the fertilizer in the drying box 1, the output shaft of the second motor 302 drives the rotating disk 303 at one end thereof to rotate. When the rotating disk 303 rotates, it drives the first limiting shell 304 on one side thereof to rotate. The first limiting shell 304 moves along with the rotating disk 303, and the adjusting ball 309 inside it pulls the connecting rod 310 to move. When the connecting rod 310 moves, it drives the adjusting plate 307 at the bottom thereof to move.
