Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to a screening and drying equipment for compound fertilizer granules. Background Technology

[0002] In the production process of compound fertilizer, drying and cooling of compound fertilizer granules are two very important processes.

[0003] Existing technology, patent document CN221133072U, provides a screening and drying device for compound fertilizer granules. The drying chamber contains a screening assembly, and a drying assembly is installed on the outside of the drying chamber at positions corresponding to the screening assembly. The screening assembly includes screening plates equidistantly installed inside the drying chamber. Each screening plate has a filter screen installed in the center, with the screen aperture diameter decreasing from large to small. A door is rotatably connected to the outside of the drying chamber, and anti-leakage gaskets are installed on the outer wall of the door at positions corresponding to the screening plates. A feed valve plate is rotatably connected to the top of the drying chamber. This invention provides a screening and drying device for compound fertilizer granules, enabling multi-stage screening of compound fertilizer and simultaneous screening and drying, improving processing efficiency, enhancing the overall practicality of the device, and bringing better application prospects.

[0004] Although the device has many beneficial effects, it still has the following problems: In the process of compound fertilizer production, large quantities are poured in, which easily leads to accumulation. The compound fertilizer inside the accumulation has a longer contact time with the gas, which results in different drying degrees between the internal and external compound fertilizer, causing trouble for the workers. To address this, we have proposed a screening and drying device for compound fertilizer particles. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the problem mentioned above, where large quantities of compound fertilizer are poured in during production, leading to accumulation and prolonged contact between the compound fertilizer and the gas, resulting in uneven drying between the internal and external layers and causing inconvenience for workers, this utility model was proposed.

[0008] Therefore, the purpose of this utility model is to provide a screening and drying device for compound fertilizer granules. A motor drives a rotating rod, which in turn drives a first gear, which in turn drives a second gear. The second gear then drives a stirring rod, which in turn drives stirring blades, facilitating the stirring of the fertilizer during drying. This improves the uniformity and efficiency of drying. Simultaneously, an air outlet is provided on the surface of the stirring rod to ensure that gas is blown from the inside of the fertilizer to the outside, quickly expelling internal moisture and significantly improving drying efficiency. A hot air blower effectively utilizes its negative pressure to generate suction, which in turn drives the suction pipe to draw in air. The air is then converted into hot air by the hot air blower and discharged through the air outlet and vent, facilitating the drying process of the fertilizer.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a screening and drying device for compound fertilizer granules, including:

[0035] Please see Figures 1-5 This embodiment of a compound fertilizer granule screening and drying device includes a drying chamber 1. A shell 2 is fixedly connected to the right side of the drying chamber 1. A motor 13 is fixedly installed on the top left side of the inner cavity of the shell 2 by a first fixing bolt. A rotating rod 11 is fixedly connected to the right side of the motor 13. A first gear 12 is sleeved on the left side of the rotating rod 11. A second gear 14 meshes with the bottom of the first gear 12. A stirring rod 8 is sleeved in the inner cavity of the second gear 14. The left side of the stirring rod 8 extends through the inner cavity of the drying chamber 1 and is fixedly connected to a stirring arm. The mixing blade 6 and the stirring rod 8 have air outlets 7 on their surfaces. The bottom of the inner cavity of the housing 2 is fixedly connected to the box body 15. The right side of the bottom of the inner cavity of the box body 15 is fixedly installed with a hot air blower 21 by a second fixing bolt. The left side of the hot air blower 21 is fixedly connected to the suction pipe 20. The top of the hot air blower 21 is fixedly connected to the air outlet pipe 17. The top of the box body 15 is fixedly connected to the fixing plate 16. The surface of the fixing plate 16 is fixedly connected to the bearing 18. Both sides of the bearing 18 are sleeved to one end of the stirring rod 8 and the air outlet pipe 17.

[0036] It is worth noting that, in order to protect the hot air blower 21, a filter box 19 is fixedly connected to the bottom left side of the inner cavity of the housing 15. A filter plate 25 is fixedly connected to the bottom of the inner cavity of the filter box 19. A HEPA filter element 23 is fixedly connected to the bottom left side of the inner cavity of the filter plate 25, and a PP filter element 24 is fixedly connected to the bottom right side of the filter plate 25. The absorbed air can be effectively filtered through the filter plate 25. The HEPA filter element 23 can filter lint, and the PP filter element 24 can filter fine particulate impurities, which improves the filtration efficiency and prevents impurities in the air from damaging the internal parts of the hot air blower 21, thereby improving the drying efficiency.

[0037] Next, in order to facilitate the maintenance of the filter plate 25, specifically, mounting blocks are fixedly connected to both sides of the filter plate 25, and mounting bolts are provided on the surface of the mounting blocks. The mounting blocks and mounting bolts facilitate the disassembly and maintenance of the filter plate 25.

[0038] Meanwhile, in order to facilitate air absorption, specifically, an air inlet 22 is provided at the bottom of the inner cavity of the filter box 19, and a through hole 10 is provided on the left side of the bottom of the inner cavity of the housing 2. The air inlet 22 and the through hole 10 are symmetrical, and air can enter through the air inlet 22 and the through hole 10.

[0039] Furthermore, to facilitate material discharge, specifically, a discharge port 5 is provided at the bottom of the inner cavity of the drying box 1, and a baffle 4 is inserted into the inner cavity of the discharge port 5.

[0043] Combination Figures 1-5 The specific usage process of the sieving and drying equipment for compound fertilizer granules in this embodiment is as follows:

[0044] 1. According to the actual use, the user pours the fertilizer to be dried into the inner cavity of the drying box 1 through the feed inlet 9. Then, the user starts the motor 13 and the hot air blower 21 simultaneously through the external controller. The hot air blower 21 can effectively use its own negative pressure to generate suction and drive the suction pipe 20 to absorb air. The air enters the inner cavity of the filter box 19 through the air inlet 22 and the through hole 10. The absorbed air can be effectively filtered through the filter plate 25. The HEPA filter element 23 can filter lint, and the PP filter element 24 can filter fine particulate impurities, which improves the filtration efficiency and avoids the damage of the internal parts of the hot air blower 21 caused by the impurities in the air, thereby improving the drying efficiency. When the filtered gas is converted into hot air by the hot air blower 21, it is discharged through the air outlet 17 and the air outlet 7, which facilitates the drying of fertilizer.

[0045] 2: Simultaneously, the motor 13 drives the rotating rod 11 to rotate, which in turn drives the first gear 12 to rotate. The first gear 12 drives the second gear 14 to rotate, which in turn drives the stirring rod 8 to rotate. The stirring rod 8 drives the stirring blade 6, which facilitates the stirring of the dried fertilizer, thereby improving the uniformity of drying. At the same time, the air outlet 7 opened on the surface of the stirring rod 8 ensures that the gas is blown from the inside of the fertilizer to the outside, and the internal moisture is quickly discharged to the outside, which greatly improves the drying efficiency.

[0046] 3: After the fertilizer is dried, the user pulls the baffle 4 and pulls the baffle 4 out of the inner cavity of the discharge port 5. Then the fertilizer can be discharged from the inner cavity of the discharge port 5.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
