Description

Technical Field

[0001] This utility model relates to the field of fertilizer production, specifically a fertilizer drying device for fertilizer production. Background Technology

[0002] Fertilizers are substances that provide essential nutrients for plant growth, primarily used to replenish soil nutrients and improve crop yield and quality. They can be categorized by source into organic fertilizers and chemical fertilizers; and by function into base fertilizers, top dressings, and foliar fertilizers. The core components of fertilizers include nitrogen, phosphorus, potassium, and trace elements such as calcium and magnesium. Fertilizers require drying during production.

[0003] For example, authorization announcement number CN222335975U discloses a fertilizer drying device for fertilizer production, belonging to the field of fertilizer drying technology. It includes a drying tank and a feed inlet installed at the top of the drying tank. The inner wall of the bottom middle section of the drying tank tapers from top to bottom, and a discharge port is installed at the bottom middle section. A cylinder is installed vertically in the middle of the inner cavity of the drying tank. This invention enables the fertilizer accumulated in the middle of the bottom inner cavity of the drying tank to be conveyed from bottom to top through the inner cavity of the cylinder and fall from the feed inlet, realizing the circulation and conveying of fertilizer within the drying tank. During this process, the hot air inside the drying tank is used to dry the fertilizer. Combined with the upward circulation and dispersion of the fertilizer, it allows for more comprehensive and thorough drying. Furthermore, it enables multi-angle circumferential stirring of the fertilizer within the drying tank, promoting all-round drying. Compared to a single stirring component, this shortens the fertilizer drying time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a fertilizer drying device for fertilizer production, comprising a support platform 1, a heating seat 101 fixedly connected to the upper end of the support platform 1, a drying tank 2 rotatably mounted on the upper end of the heating seat 101, a support ring 201 fixedly connected to one side of the drying tank 2, a support column 3 disposed inside the support ring 201, an inclined feed pipe 4 fixedly connected to the middle of the support column 3, a rotating shaft 5 rotatably connected to the middle of the inclined feed pipe 4, a plurality of dispersing rods 501 arranged in a ring on the rotating shaft 5, the lower end of the inclined feed pipe 4 extending in an inclined direction into the interior of the drying tank 2 and having a spraying notch 402 at its upper end, the lower end of the rotating shaft 5 extending in an inclined direction into the spraying notch 402 of the inclined feed pipe 4 and having two spraying plates 502 fixedly connected thereto, and a bearing connecting the outer wall of the support column 3 and the inner wall of the support ring 201. 203 Rotary Connection: The support column 3 extends from the side away from the drying tank 2 into the support ring 201 and is fixed to the upper end of the support platform 1 by a bracket. The inclined feed pipe 4 extends from the upper end of the support column 3 and is fixedly connected to the upper end of the feed hopper 401. Fertilizer is fed into the inclined feed pipe 4 through the feed hopper 401. As the fertilizer flows into the drying tank 2 inside the inclined feed pipe 4, the rotating shaft 5 drives multiple sets of dispersing rods 501 to rotate, which fully disperses the flowing fertilizer and the agglomerated lumps. The dispersed raw material flows downward and is simultaneously driven by the rotating shaft 5 to rotate the spraying plate 502. The spraying plate 502 throws the dispersed raw material upward through the spraying notch 402 into the drying tank 2 for further dispersion, preventing the fertilizer from accumulating when entering the drying tank 2 and affecting the drying effect.

[0024] Please see Figure 1 and Figure 2 The drying tank 2 is supported by roller support mechanisms 102 on both sides of the front and rear ends and the upper surface of the support platform 1. The inner wall of the drying tank 2 is fixedly connected with spiral pusher blades 205. The middle of the side of the drying tank 2 away from the support ring 201 is provided with a discharge port 204. The upper side of the support platform 1 is fixedly connected with a first drive motor 103. The output shaft of the first drive motor 103 is fixedly connected with a gear 104. The middle of the outer wall of the support ring 201 is fixedly connected with a ring tooth 202. The ring tooth 202 is meshed with the teeth of the gear 104. The first drive motor 103 drives the drying tank 2 to rotate. The fertilizer inside the drying tank 2 is pushed to the discharge port 204 by the spiral pusher blades 205 and discharged. When the drying tank 2 rotates, it is heated by the heating seat 101 to dry the flowing fertilizer.

[0025] Please see Figure 2 and Figure 4The inclined feed pipe 4 extends from the upper end of the support column 3 in the inclined direction and is fixedly connected to the drive device 6 on one side. The drive device 6 is fixedly equipped with a second drive motor 601. One end of the rotating shaft 5 extends into the drive device 6 and is fixedly connected to the output shaft of the second drive motor 601. The second drive motor 601 drives the rotating shaft 5 to rotate.

[0026] Please see Figure 2 and Figure 4 An exhaust fan 301 is fixedly installed at the lower middle part of the side of the support column 3 away from the drying tank 2. An exhaust pipe 302 is fixedly connected to one side of the exhaust fan 301. The end of the exhaust pipe 302 away from the exhaust fan 301 passes through the support column 3 and extends into the interior of the drying tank 2. The exhaust fan 301 and the exhaust pipe 302 discharge the moisture generated inside the drying tank 2.

[0027] Working Principle: During operation, the fertilizer to be dried is continuously fed into the inclined feed pipe 4 through the feed hopper 401. The second drive motor 601 drives the rotating shaft 5, which in turn drives the dispersing rod 501 to rotate at high speed, breaking up and dispersing the falling fertilizer to prevent clumping. When the dispersed fertilizer flows to the spraying notch 402, it is evenly sprayed into the drying tank 2 by the synchronously rotating spraying plate 502. Simultaneously, the first drive motor 103 drives the drying tank 2 to rotate through the meshing of the gear 104 and the ring gear 202, which, in conjunction with the spiral pusher blades 205 on the inner wall, propels the fertilizer towards the discharge port 204. During this process, the heating seat 101 heats the rotating drying tank 2, ensuring uniform heating of the fertilizer during dynamic conveying and sufficient evaporation of moisture. The exhaust fan 301 continuously discharges moisture from the tank through the exhaust pipe 302, accelerating the drying process. Finally, the dried fertilizer is continuously discharged from the discharge port 204, realizing continuous automated drying operations in fertilizer production.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
