Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer granulation cooling device. Background Technology
[0002] During fertilizer production, granulated fertilizer granules are usually at high temperatures, which is not only detrimental to subsequent packaging and storage, but may also cause changes in some components of the fertilizer due to high temperatures, affecting its quality and fertilizer efficacy. Therefore, it is necessary to cool the granulated fertilizer.
[0003] Traditional fertilizer cooling methods are mostly simple, such as natural cooling. These methods are extremely inefficient and time-consuming, and cannot meet the needs of modern large-scale fertilizer production. Common air-cooling equipment also has some problems in the cooling process. On the one hand, the cooling is uneven, and some fertilizers are easily over-cooled while others are under-cooled, thus failing to meet the usage requirements. To address this, we propose a fertilizer granulation cooling device. Utility Model Content

This device solves the problem that traditional fertilizer cooling methods are mostly simple, such as natural cooling, which is extremely inefficient, time-consuming, and cannot meet the needs of modern large-scale fertilizer production. Common air-cooled equipment also has some problems during the cooling process. On the one hand, cooling is uneven, easily resulting in some fertilizer being over-cooled while others are under-cooled, thus failing to meet usage requirements.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer production granulation cooling device, comprising a shell, a granulator connected to the top of the shell, a mesh cylinder provided at the bottom of the shell, an inclined plate provided in the inner cavity of the shell, a fan fixedly connected to the right side of the back of the shell, an exhaust pipe connected to one side of the fan, a first nozzle connected to one side of the exhaust pipe, a second nozzle connected to the other side of the exhaust pipe, a dual-shaft motor fixedly connected to the bottom of the right side of the shell, and an auger fixedly connected to the left side of the dual-shaft motor.
[0006] Preferably, a rotating shaft is fixedly connected to the right side of the mesh cylinder, and a reciprocating screw is movably connected to the top of the right side of the housing. A threaded sleeve is threadedly connected to one side of the reciprocating screw, and a connecting rod is fixedly connected to one side of the threaded sleeve. One side of the connecting rod is fixedly connected to the inclined plate.
[0007] Preferably, a guide pipe is movably connected to the left side of the mesh cylinder, and one side of the guide pipe is in communication with the shell.
[0008] Preferably, vertical rods are fixedly connected to the four corners of the bottom of the shell, and a fixing ring is fixedly connected to the bottom of the vertical rod. An annular groove is formed on the inner surface of the fixing ring, and a slider is slidably connected to the inner cavity of the annular groove. One side of the slider is fixedly connected to the mesh cylinder.

[0011] Preferably, both sides of the inclined plate are fixedly connected to sliding sleeves, and the inner cavity of the sliding sleeve is slidably connected to a sliding rod, and one side of the sliding rod is fixedly connected to the housing.
[0012] Compared with the prior art, this utility model provides a fertilizer production granulation cooling device, which has the following beneficial effects:
[0013] 1. After granulation, the material falls onto the surface of the inclined plate and rolls on it. At the same time, the fan is activated to draw in outside gas. Then, some of the gas is sprayed onto the surface of the rolling material through the exhaust pipe and the first nozzle for cooling. The material then falls to the bottom of the inner cavity of the shell. The dual-shaft motor is activated to drive the auger to rotate, which moves the material to the left.

[0023] The specific function of this technical solution is as follows: After granulation, the material falls onto the surface of the inclined plate 4 and rolls on the surface of the inclined plate 4. At the same time, the fan 5 is started to draw in external gas, and then some of the gas is sprayed onto the surface of the rolling material through the exhaust pipe 6 and the first nozzle 7 to cool it. Then the material falls to the bottom of the inner cavity of the shell 1. The dual-shaft motor 9 is started, which drives the auger 10 to rotate, thereby moving the material to the left. Then it is discharged into the inner cavity of the mesh cylinder 3 through the guide pipe 18. Some of the gas is sprayed out through the second nozzle 8, which comes into contact with the material in the inner cavity of the mesh cylinder 3 and cools it again, making the cooling process highly efficient. Example 2
[0024] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rotating shaft 11 is fixedly connected to the right side of the mesh cylinder 3, a reciprocating screw 12 is movably connected to the top right side of the housing 1, a threaded sleeve 14 is threadedly connected to one side of the reciprocating screw 12, a connecting rod 15 is fixedly connected to one side of the threaded sleeve 14, and one side of the connecting rod 15 is fixedly connected to the inclined plate 4. A connecting shaft is fixedly connected to the right side of the dual-axis motor 9, and a synchronous pulley 16 is fixedly connected to the surface of the connecting shaft, the right side of the rotating shaft 11, and the right side of the surface of the reciprocating screw 12. A synchronous belt 17 meshes with the surface of the synchronous pulley 16, and a fixed frame 13 is movably connected to the right side of the reciprocating screw 12 via a bearing.

[0025] The specific function of this technical solution is as follows: The operation of the dual-axis motor 9 will cause the rotating shaft 11 and the reciprocating lead screw 12 to rotate. The reciprocating lead screw 12 drives the threaded sleeve 14 to move, the threaded sleeve 14 drives the connecting rod 15 to move, and the connecting rod 15 drives the inclined plate 4 to move back and forth, so that the material at the top of the inclined plate 4 can be dispersed. The rotating shaft 11 will drive the mesh cylinder 3 to rotate, thereby causing the internal material to tumble, thus making the cooling uniform and the cooling effect good.
[0026] Working principle: After granulation, the material falls onto the surface of the inclined plate 4 and rolls on the surface of the inclined plate 4. At the same time, the fan 5 is started to draw in the outside air, and then some of the air is sprayed onto the surface of the rolling material through the exhaust pipe 6 and the first nozzle 7 to cool it. Then the material falls to the bottom of the inner cavity of the shell 1. The dual-shaft motor 9 is started, which drives the auger 10 to rotate, thereby moving the material to the left. Then it is discharged into the inner cavity of the mesh cylinder 3 through the guide pipe 18. Some of the air is sprayed out through the second nozzle 8 to contact the material in the inner cavity of the mesh cylinder 3 and cool it again, making the cooling process highly efficient.
[0027] The operation of the dual-axis motor 9 causes the rotating shaft 11 and the reciprocating lead screw 12 to rotate. The reciprocating lead screw 12 drives the threaded sleeve 14 to move, the threaded sleeve 14 drives the connecting rod 15 to move, and the connecting rod 15 drives the inclined plate 4 to move back and forth, so that the material on the top of the inclined plate 4 can be dispersed. The rotating shaft 11 drives the mesh cylinder 3 to rotate, thereby causing the internal material to tumble, thus making the cooling uniform and the cooling effect good.
