Description

Technical Field

[0001] This utility model relates to the field of fertilizer granulation technology, specifically to a high-pressure atomization granulation device for fertilizer. Background Technology

[0002] Fertilizers are substances that provide essential nutrients for plant growth and development, improve soil properties, or regulate plant growth. They play a crucial role in agricultural production. Fertilizer granulation is the process of processing powdered, liquid, or slurry fertilizer raw materials into particles with a certain size, strength, and shape. For liquid fertilizers, high-pressure atomization granulation devices are now commonly used to complete the granulation operation. In practice, these devices offer advantages such as stable granulation, safe use, and structural stability.

[0003] The prior art discloses a spray drying granulation tower with application number CN201721690273.9. In the above-mentioned utility model, the atomized fertilizer enters the granulation space. When the hot air discharged through the hot air pipe comes into contact with the atomized fertilizer, the water in the atomized fertilizer evaporates rapidly, and the fertilizer solute gradually crystallizes and condenses to form fine particles. The hot air pipe is used in a fixed position, which cannot allow the hot air to fully contact the atomized fertilizer. At the same time, some atomized fertilizer in the granulation space cannot be successfully granulated. Without a collection structure, the atomized fertilizer will be discharged from the granulation space along with the fertilizer particles.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-pressure atomization granulation device for fertilizers, which has the advantages of being able to adjust the position of the hot air pipe to ensure that the hot air can fully contact the atomized fertilizer and having a collection structure to collect the atomized fertilizer that has not been successfully granulated, thereby solving the problems in the background technology mentioned above.

[0006] To achieve the advantages of adjustable hot air duct positioning, ensuring sufficient contact between hot air and atomized fertilizer, and having a collection structure to collect ungranulated atomized fertilizer, the specific technical solution adopted by this utility model is as follows: A high-pressure atomization granulation device for fertilizer includes a shell, a hopper fixedly extending through the lower part of the shell, and an electric slide valve installed at the discharge end of the hopper. Multiple sets of tilting boxes are arranged inside the shell, each set containing an absorbent sponge.

One end of each set of liquid guide pipes is inserted into the shell, and a high-pressure valve is installed at the opposite ends of each set of liquid guide pipes. The atomizer has a mounting cover on its upper part. A shaft tube passes through the upper part of the housing and the mounting cover via a bearing. A hot air blower and a drive motor are mounted on the upper part of the mounting cover. An air guide tube is snapped onto the output end of the hot air blower. A first jet pipe is fixedly sleeved onto the lower end of the shaft tube, and a connecting pipe is fixedly sleeved through the side wall of the first jet pipe. A second jet pipe is fixedly sleeved onto the lower side wall of the connecting pipe. Multiple nozzles are fixedly sleeved through the side walls of the first and second jet pipes.

[0012] Compared with the prior art, this utility model provides a fertilizer high-pressure atomization granulation device, which has the following beneficial effects: (1) This utility model adopts a shaft tube, a first jet pipe, a connecting pipe and a second jet pipe. The shaft tube, the first jet pipe, the second jet pipe and the main gear and the driven gear form a dynamic hot air distribution structure. The drive motor drives the first jet pipe and the second jet pipe to rotate, so that the hot air can contact the atomized fertilizer from multiple angles and in all directions, eliminate the hot air blind spot, accelerate the water evaporation speed and improve the heat exchange efficiency.

[0013] (2) This utility model adopts an inclined box and a water-absorbing sponge. The collection structure composed of the inclined box and the water-absorbing sponge, with its interception design and convenient maintenance structure, can not only effectively collect the atomized fertilizer that has not been successfully granulated and reduce the content of fine powder in the finished product, but also realize resource recycling through the reuse of the water-absorbing sponge and solution recycling, thus achieving both environmental protection and economic benefits.

One end of the air guide pipe 20 is connected to the upper end of the shaft tube 12 via a bearing to prevent the air guide pipe 20 from obstructing the rotational movement of the shaft tube 12. The lower end of the shaft tube 12 is fixedly sleeved with a first jet pipe 13, and a connecting pipe 14 is fixedly passed through the side wall of the first jet pipe 13. The lower side wall of the connecting pipe 14 is fixedly sleeved with a second jet pipe 15. The side walls of the first jet pipe 13 and the second jet pipe 15 are fixedly passed through multiple... The nozzle 21 has a main gear 18 fixedly sleeved at the output end of the drive motor 17, and a driven gear 19 fixedly sleeved on the side wall of the shaft tube 12. The shaft tube 12, the first jet pipe 13, the second jet pipe 15, the main gear 18, and the driven gear 19 constitute a dynamic hot air distribution structure. The drive motor 17 drives the first jet pipe 13 and the second jet pipe 15 to rotate, so that the hot air can contact the atomized fertilizer from multiple angles and in all directions, eliminating hot air blind spots, accelerating the water evaporation rate, and improving heat exchange efficiency.

[0019] Please see Figure 1 and Figure 4 Multiple openings 22 are provided on both sides of the outer shell 1, and each of the multiple openings 22 is fitted with a sealing plug 23. Multiple tilting boxes 4 are fixedly connected to the inner ends of the multiple sealing plugs 23. The collection structure composed of the tilting box 4 and the water-absorbing sponge 5, with its interception design and convenient maintenance structure, can not only effectively collect the atomized fertilizer that has not been successfully granulated, reducing the fine powder content of the finished product, but also achieve resource recycling through the reuse of the water-absorbing sponge 5 and solution recycling, thus achieving both environmental protection and economic benefits.

[0020] Please see Figure 1 and Figure 4 Each of the multiple sealing plugs 23 has a handle installed on its external end, which facilitates the movement and use of the multiple sealing plugs 23.

[0021] Please see Figure 1The lower part of the outer shell 1 is equipped with four sets of support legs, which serve to support and fix the outer shell 1.

[0022] Please see Figure 1 and Figure 2 The main gear 18 and the driven gear 19 mesh with each other, ensuring that the main gear 18 can drive the driven gear 19 to rotate.

[0023] Please see Figure 1 and Figure 3 The control panel is installed on the end face of the outer casing 1. The control panel is electrically connected to the electric gate valve 3, two sets of high-pressure pumps 7, hot air blower 16 and drive motor 17 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art. It is common knowledge in the art. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0024] Working principle: In actual use of the fertilizer high-pressure atomization granulation device, the control panel is used to operate the two sets of high-pressure pumps 7. The liquid fertilizer inside the two sets of storage tanks 6 can be drawn into the two sets of high-pressure atomizers 10 through the two sets of liquid extraction pipes 8 and the two sets of liquid guide pipes 9. Finally, the atomized fertilizer can be sprayed out through the two sets of high-pressure atomizers 10. The sprayed atomized fertilizer will enter the interior of the outer shell 1. At the same time, the control panel is used to open and close the electric slide valve 3, and to operate the hot air blower 16 and the drive motor 17. Hot air can enter the first air intake through the air guide pipe 20 and the shaft pipe 12. Inside the jet pipe 13, some hot air can enter the second jet pipe 15 through the connecting pipe 14. Finally, the hot air can be ejected through multiple nozzles 21. When the atomized fertilizer comes into contact with the hot air, it forms fertilizer granules. During this process, the output of the drive motor 17 drives the main gear 18 to rotate. Since the main gear 18 meshes with the driven gear 19, the rotating main gear 18 can drive the driven gear 19 to rotate. The rotating driven gear 19 can drive the first jet pipe 13 and the second jet pipe 15 to rotate through the shaft pipe 12. At this time, the position of the hot air ejection can be adjusted. Through the shaft pipe 12, the first jet pipe 13, the connecting pipe 14, and the second jet pipe 15, the position of the hot air duct can be adjusted to ensure that the hot air can fully contact the atomized fertilizer, improving the practicality of the high-pressure atomized fertilizer granulation device. Simultaneously, according to the above operation, the atomized fertilizer can form fertilizer granules inside the outer shell 1. Some atomized fertilizer that has not been successfully granulated will move downwards. During this process, the ungranulated atomized fertilizer will come into contact with multiple water-absorbing nozzles. The sponge 5 prevents the atomized fertilizer from being discharged along with the fertilizer granules through the hopper 2. When it is necessary to clean the water-absorbing sponge 5, the worker can pull multiple sets of handles by hand. Multiple sets of handles can be used to remove multiple sets of tilting boxes 4 through multiple sets of sealing plugs 23. Then, multiple sets of water-absorbing sponges 5 can be removed for cleaning. After cleaning, multiple sets of sealing plugs 23 can be reset. Through the set tilting boxes 4 and water-absorbing sponges 5, a collection structure is provided to collect atomized fertilizer that has not been successfully granulated, which brings convenience to the collection of atomized fertilizer in the high-pressure atomization granulation device.
