[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. Fertilizers are generally divided into organic fertilizers, inorganic fertilizers, and biological fertilizers. They can also be divided into farmyard fertilizers and chemical fertilizers according to their sources. No matter what kind of fertilizer, it needs to go through multiple processing steps during the production and processing. In order to quickly bag it, a cooling device is generally used to cool the processed fertilizer.

[0024] See also Figure 1 and Figure 5 , Figure 1 and Figure 5A cooling device for fertilizer production in an embodiment of the utility model comprises a barrel 1, a blowing member 2 and a lifting mechanism 3. A feed port 11 is arranged at the top of the barrel 1. The inner diameter of the bottom of the barrel 1 is gradually reduced. The blowing member 2 is connected to the inner bottom of the barrel 1. The lifting mechanism 3 is coaxially arranged in the barrel 1. The lifting mechanism 3 can be used to lift the fertilizer at the inner bottom of the barrel 1 toward the top of the barrel 1 and discharge it to the outside of the barrel 1. The cooling device also comprises a water cooling mechanism 4 and a plurality of slow flow plates 5. The water cooling mechanism 4 comprises a cooling pipe 41, a liquid pumping part 42 and a water storage tank 43, the cooling pipe 41 is fixedly mounted on the lifting mechanism 3, an annular cooling cavity is formed between the cooling pipe 41 and the lifting mechanism 3, the water storage tank 43 is connected with the water inlet of the cooling cavity via the liquid pumping part 42, and the water outlet of the cooling cavity is connected with the water storage tank 43 to form a circulation pipeline; a plurality of slow flow plates 5 are respectively arranged on the inner wall of the cylinder 1 and the outer wall of the cooling pipe 41 to form a curved channel between the inner wall of the cylinder 1 and the outer wall of the cooling pipe 41.

[0025] In this specific embodiment, the blowing member 2 is an air cooler, which transports cold air into the cylinder 1 to cool the fertilizer. It should be noted that the multiple slow flow plates 5 are staggered, which can extend the path of the fertilizer when falling in the cylinder 1, extend the time for the fertilizer to fall from the top of the cylinder 1 to the bottom, and increase the contact area between the fertilizer and the cold air.

[0026] On the basis of the above solution, in order to ensure that the cold air can be evenly dispersed into the cylinder 1, specifically, please refer to Figure 1 and Figure 5 The inner wall near the lower end of the cylinder 1 is provided with an annular air guide cavity 11a, which is connected to the blowing member 2 and has a plurality of air holes 11b. The cold air flow delivered to the air guide cavity 11a by the blowing member 2 can be dispersed into the cylinder 1 through the plurality of air holes 11b.

[0027] It should be noted that the lifting mechanism 3 is not limited to a specific structure, as long as it can lift the fertilizer at the bottom of the cylinder 1 toward the top of the cylinder 1 and discharge it to the outside of the cylinder 1, no other limitations are made here.

[0028] In this specific embodiment, please refer to Figure 2 and Figure 3The lifting mechanism 3 includes a lifting tube 31, a rotating shaft 32, a spiral blade 33 and a reduction motor 34. The lifting tube 31 is coaxially built into the cylinder 1. The lower end of the lifting tube 31 is provided with a feed hole 311 connected to the bottom of the cylinder 1. The upper end of the lifting tube 31 is provided with a discharge pipe 312 extending out of the cylinder 1. A cooling pipe 41 is fixedly provided on the lifting tube 31 between the feed port 11 and the discharge pipe 312. The rotating shaft 32 is coaxially built into the lifting tube 31.

[0029] Specifically, the fertilizer enters the lifting pipe 31 through the feeding hole 311. When the reduction motor 34 drives the rotating shaft 32 to rotate, the spiral blades 33 can drive the fertilizer to rise in the lifting pipe 31, and the cooling water in the cooling cavity can cool the rising fertilizer.

[0030] On the basis of the above scheme, in order to ensure that the fertilizer can be evenly distributed in the cylinder 1, specifically, the upper end of the lifting pipe 31 is provided with a balancing hopper 313 corresponding to the corresponding feed port 11, and the balancing hopper 313 is overall arranged in a conical shape upward.

[0031] In this specific embodiment, an inspection door 12 is provided at the bottom of the cylinder 1. By opening the inspection door 12, it is convenient for operators to inspect the components in the cylinder 1. In addition, in order to facilitate observation of the working status in the cylinder 1, specifically, an observation window 13 is embedded at the bottom of the cylinder 1.

[0032] It should be noted that a large amount of dust-containing gas will be generated when the fertilizer is cooled. In order to avoid direct discharge of dust-containing gas to cause air pollution, an exhaust pipe 14 is also provided at the top of the cylinder 1. In other embodiments, the exhaust pipe 14 can be connected to a pulse dust removal device, which can better filter out dust in the air.

[0034] On the basis of the above solution, in order to prevent the fertilizer from being accumulated on the slow flow plate 5, specifically, the slow flow plates 5 all have a protrusion extending upward. In this specific embodiment, the slow flow plate 5 is V-shaped as a whole.

[0035] In one embodiment, a conveying mechanism 6 for conveying fertilizer is provided below the discharge pipe 312. Specifically, the conveying mechanism 6 can be a common belt conveyor on the market, through which the cooled fertilizer is conveyed to a designated location for packaging and storage.

[0036] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0037] The fertilizer is transported to the cylinder 1 through the feed port 11. When the fertilizer falls to the bottom of the cylinder 1 in the curved channel, it comes into contact with the cold air transported to the cylinder 1 by the blowing member 2, and the fertilizer is cooled down. Subsequently, the fertilizer enters the lifting pipe 31 through the feed hole 311. When the reduction motor 34 drives the rotating shaft 32 to rotate, the spiral blades 33 can drive the fertilizer to rise in the lifting pipe 31, and the cooling water in the cooling cavity can cool the rising fertilizer. After cooling, the fertilizer is discharged to the outside of the cylinder 1 through the discharge pipe 312.

[0038] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
