[0002] High nitrogen compound fertilizer refers to compound fertilizer with a high nitrogen ratio. It is usually used to provide the nitrogen element required by plants to promote plant growth and development. After granulation, it needs to be cooled to prevent the compound fertilizer particles from sticking together and ensure the granularity of the fertilizer.

[0004] In response to the above-mentioned related problems, when cooling the compound fertilizer particles, cold air is introduced to cool the compound fertilizer particles. During the blowing of the cold air, the dust on the surface of the particles will separate from the main body, thereby generating fertilizer smoke. When a large amount of fertilizer is cooled, a large amount of smoke will be generated, which will affect the health of the operators and pollute the environment. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Example 1

[0032] Reference Figure 1-Figure 4 , which is the first embodiment of the utility model, and provides an energy-saving dust-free cooling device for high-nitrogen compound fertilizer, comprising a cooling box 1, a feeding assembly 2 is arranged on the top of the cooling box 1, a dust removal assembly 3 is arranged on the back of the cooling box 1, and a cooling assembly 4 is arranged inside the cooling box 1;

[0033] The dust removal assembly 3 includes a dust removal box 32, a connecting pipe 31 is fixedly installed between the top of the dust removal box 32 and the top of the cooling box 1, the connecting pipe 31 connects the dust removal box 32 with the interior of the cooling box 1, a dust removal filter element 33 is fixedly installed inside the dust removal box 32, an air outlet 8 is fixedly installed on the left side of the dust removal box 32, and an air inlet 6 is fixedly installed on the left side of the cooling box 1.

[0034] Specifically, the cooling assembly 4 includes a first guide net 41 and a second guide net 42. The first guide net 41 is fixedly mounted on the left inner wall of the cooling box 1, and the second guide net 42 is fixedly mounted on the right inner wall of the cooling box 1. The first guide net 41 and the second guide net 42 are arranged alternately. The cooling assembly 4 also includes a first fan 43 and a second fan 44. The first fan 43 is fixedly mounted at the connection between the cooling box 1 and the air inlet 6. The second fan 44 is fixedly mounted at the connection between the dust removal box 32 and the air outlet 8. The feeding assembly 2 includes an upper hopper 21, which is fixedly mounted at the upper right corner of the cooling box 1. A feed trough 24 is provided at the connection between the upper hopper 21 and the cooling box 1. The feed trough 24 is a long and narrow strip.

[0035] Furthermore, the external cold air enters the cooling box 1 through the air inlet 6, enters the connecting pipe 31 through the cooling box 1, and then enters the dust removal box 32, and finally is discharged from the air outlet 8. The first fan 43 and the second fan 44 installed inside the air inlet 6 and the air outlet 8 can form an air duct inside to speed up the flow rate of the internal gas.

[0036] When cooling the fertilizer, the fertilizer rolls down through the second guide net 42 at the top. The rolling time of the fertilizer is ensured by the second guide net 42 and the first guide net 41. When rolling, cold wind blows upward from the bottom, and the wind passes through the gaps between the fertilizers and thus passes through the holes on the guide net. When the cold wind passes through, the heat in the fertilizer is taken away, and the cooling effect is ensured through the process of the fertilizer from top to bottom.

[0037] The air accelerated by the fan can carry the tiny dust generated during the cooling process and flow synchronously with the air. The dust will enter the dust removal box 32 below through the connecting pipe 31. After entering the dust removal box 32, the gas and dust will pass through the dust removal filter 33. After passing through the dust removal filter 33, the dust will remain on the dust removal filter 33, and the gas will be discharged from the air outlet 8 through the dust removal filter 33, thereby achieving the effect of preventing a large amount of dust from being dispersed while cooling.

[0038] Example 2

[0039] Reference Figure 1-Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. A stirring rod 23 is rotatably connected between the front and rear sides of the upper hopper 21, and a motor 22 is fixedly installed on the back of the upper hopper 21. The output end of the motor 22 passes through the side wall of the upper hopper 21 and is fixedly connected to the stirring rod 23.

[0040] Specifically, a discharge trough 7 is opened on the right side of the cooling box 1, and a discharge plate 5 is fixedly installed on the right side of the lowest first guide net 41. The discharge plate 5 and the lowest first guide net 41 are in the same straight line. The discharge plate 5 passes through the interior of the discharge trough 7, and the bottom of the discharge plate 5 is attached to the inner bottom wall of the discharge trough 7.

[0041] Furthermore, before the fertilizer is cooled, the fertilizer is placed inside the upper hopper 21, and the motor 22 is started to drive the stirring rod 23 to rotate. The rotation of the stirring rod 23 can drive the internal fertilizer to flow quickly. The fast-flowing fertilizer can increase the rate at which the fertilizer enters the cooling box 1 through the feed trough 24, and the narrow feed trough 24 can ensure the stacking thickness of the fertilizer falling on the guide net. By reducing the overall thickness of the fertilizer when it moves, the speed of the cold air passing through can be guaranteed to be higher, thereby improving the cooling effect.

[0042] Working principle: the air accelerated by the fan can carry the tiny dust generated in the cooling process and flow synchronously with the air. The dust will enter the dust removal box 32 below through the connecting pipe 31. After entering the dust removal box 32, the gas and dust will pass through the dust removal filter 33. After passing through the dust removal filter 33, the dust will remain on the dust removal filter 33, and the gas will be discharged from the air outlet 8 through the dust removal filter 33, thereby achieving the effect of preventing a large amount of dust from being dispersed while cooling; before the fertilizer is cooled, the fertilizer is placed inside the upper hopper 21, and the stirring rod 23 is driven to rotate by starting the motor 22. The rotation of the stirring rod 23 can drive the internal fertilizer to flow quickly. The fast-flowing fertilizer can increase the rate at which the fertilizer enters the cooling box 1 through the feed trough 24, and the narrow feed trough 24 can ensure the stacking thickness of the fertilizer falling on the guide net. By reducing the overall thickness of the fertilizer when it moves, the speed of the cold air passing through can be guaranteed to be higher, thereby improving the cooling effect.
