A Chinese patent discloses a multi-element tower melt granulation compound fertilizer production device, application number: 201920305646.9. The feeding pipe in the device can directly transport the powdered material to the middle position of the melting tank, thereby improving the fusion efficiency of the powdered material.

[0003] However, the current granulation device not only has high energy consumption in the granulation process, but the device is also prone to malfunction due to heat during long-term operation. In addition, it is restricted by the external temperature environment during its operation, and the slurry particles cannot be fully and effectively cooled during the molding process. The cooling time is often extended by increasing the height of the device. While the size of the device increases, the cooling effect is limited. Not only does it lose its portability, it is still constrained by the external temperature environment, resulting in poor molding effect of the particles and low working efficiency of the device.

[0022] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0023] 1. It is equipped with a heat extraction and shaping mechanism. Through the cooperation of the piston box, swirl box, moving piston, rotating wheel, half gear, tooth groove, tooth plate and tooth chain, a pressure and speed dual amplification structure can be constructed. In addition, the separation effect of the isolation tube and the separation seat can actively extract the heat of the slurry, and the heat of the slurry and the heat in the air are used as the driving force. While ensuring the synchronization of heat exchange work, the heat exchange efficiency is greatly enhanced, and the effective heat exchange time is equivalently enhanced, which improves the timeliness and effectiveness of heat exchange work. At the same time, it realizes the relative independence of heat exchange work and shaping and granulation work, reduces the impact of heat exchange work on the slurry, makes the slurry more uniform after molding, and improves the molding effect;

[0024] At the same time, its driving force comes from the heat of the slurry and the heat in the air, which can effectively avoid the limitations of external energy on the device, so that the device can be operated more efficiently and stably, improving the operating durability of the device, and can save a lot of energy consumption, making the device more energy-saving and environmentally friendly, and reducing the processing cost of compound fertilizer. Because it actively extracts the heat carried by the slurry through gas-liquid conversion, while improving the heat exchange efficiency, it also effectively avoids the influence of external solar terms and regions on the device, greatly improving the adaptability and anti-interference of the device to the external environment, allowing the device to perform granulation processing more freely and stably.

[0025] 2. The air pumping structure can be constructed by cooperating with the piston box, swirl box, moving piston, rotating wheel and exhaust seat. In addition, the exhaust pipe, check valve, diverter box, exchange frame, telescopic pipe, negative pressure pipe and flow stabilizing pipe can create a negative pressure environment at the top of the isolation pipe and limit the negative pressure at the top of the separation seat. On the one hand, it can offset part of the gravity exerted on the slurry during the falling process, make it layered, avoid mutual adhesion when it is not formed, and effectively extend the effective cooling time of the slurry during the falling process, equivalently make up for the falling height of the slurry, and effectively reduce the required forming size of the device, making the device more portable.

[0026] On the other hand, the reduction in air pressure will also force the vaporization point of the slurry's solvent to be relatively lower, causing part of the solvent to vaporize, further enhancing the particle forming effect, and at the same time it can slow down the drooping feeling of the slurry particles under the action of gravity, making the slurry more rounded after forming, and making the particle forming more regular and standard, effectively ensuring the product's qualified rate, and through the coordination of explosion-proof pipes, extraction pipes, pressure-resistant pipes, insulation pipes, aeration seats, flow pipes, heat exchange cylinders and sliding pipes, the airflow and refrigerant can be circulated and guided, which can not only achieve power complementarity, but also effectively strengthen the mutual promotion of various structures, while enabling the device to extract a wider range of air heat, the negative pressure state can be more balanced and stable, making the heat exchange work faster and more efficient, and the pressure limiting work of the compression box and the slider can make the device run more smoothly and efficiently.

[0027] 3. A relay control mechanism is provided. Through the cooperation of the top seat, the driving wheel and the driving rod, the driving force provided by the refrigerant can be connected and transformed. On the one hand, it is equipped with the transmission function of the rotating rod, the anti-skid wheel and the wear-resistant wheel, and the limiting function of the speed change box, the reverse wheel and the shaft rod, and the speed adjustment structure is constructed to limit the rotation speed of the choke head, which effectively improves the controllability of the slurry size sprayed from the granulation head, greatly improves the convenience of the slurry particle size control, and can meet the processing requirements of particles of different sizes according to actual needs, making the particle forming and processing work more efficient and flexible, and expanding the effective adaptability and flexibility of the device;

[0028] On the other hand, it can cooperate with the inner guide seat, scraper rod and elastic plate to construct an elastic scraper structure, and with the elastic supporting effect of the sliding cylinder, circular plate, spring and push rod, it can further use the driving force of the airflow to cause the guide seat to circulate and screen, and with the scraping effect, it can greatly improve the stability and smoothness of the device's material discharge, effectively avoid device blockage, make the device work more continuously and stably, and effectively ensure the output quality before and after the particle processing process. The overflow seat, air supply pipe, threaded ring and threaded head are coordinated to guide the airflow, and the convenience of disassembly and installation of the device is improved while effectively strengthening the airflow flow sealing of the device. The driving force can be converted and utilized more efficiently and stably, and the effective energy utilization rate of the device is improved. The exhaust gas can be guided and filtered by cooperating with the outlet valve and the filter box, which greatly enhances the energy-saving and environmental protection performance of the device.

[0029] In summary, the granulation device can effectively utilize the heat emitted by the slurry and the heat in the air to enhance the granulation effect, so that the slurry can obtain more sufficient heat exchange time, can be molded and cooled more quickly and efficiently, and can greatly reduce energy consumption. It can make full use of the heat in the external air and improve the adaptability to the external environment, so that the device can operate more efficiently and stably in various complex environments, and can improve the roundness and size controllability of the granulated particles, greatly reducing the probability of clogging of the device.

[0058] A plurality of sliding cylinders 315 are installed at the bottom of the partition seat 202 in the tower body 100 and are rotated at equal angles in the circumferential direction. A circular plate 316 is installed in the sliding cylinder 315. A spring 317 is installed at the edge of the side end face of the circular plate 316.

A scraper rod 321 is installed on the top of the curved surface, and an elastic plate 322 is installed on the end of the scraper rod 321.

The material guide seat 319 and the top of the scraper rod 321 are both matched with the partition seat 202, and the elastic plate 322 is matched with the material guide seat 319. The material guide seat 319 can increase the material unloading speed, avoid device blockage, and improve the working stability of the device.

[0059] Working principle and use process of the present invention: When the tower type compound fertilizer production granulation device is actually used, firstly, the device is stably placed on the ground of the working area, and the screw 103 is rotated to adjust the distance between the pad 104 and the threaded barrel 102 to level the device. At the same time, the relative height of the tower body 100 can be adjusted according to actual needs, so that the external material receiving device can be placed into the tower body 100, so that the external material receiving device is aligned with the material guide seat 319, and then the feeding pipe 105 is connected to the external slurry conveying pipeline;

[0060] Subsequently, the air inside the shunt box 221 is extracted through the air valve 2211, and the air pressure inside the shunt box 221 is adjusted according to actual needs, so that the space outside the telescopic tube 223 is in a negative pressure state. The negative pressure is the negative pressure threshold of the space at the top of the partition seat 202 inside the tower body 100 during the granulation process. Then, air is injected into the gear box 302 through the valve 3021, and the air pressure inside the gear box 302 is adjusted according to actual needs to change the airflow pressure on the inclined surface of the reverse wheel 306. The pressure will act on the driving wheel 305 through the shaft 307. During the rotation of the driving wheel 305, it needs to overcome the pressure before it can rotate, that is, the pressure is negatively correlated with the rotation speed of the driving wheel 305. The adjustment work can also be adjusted in real time according to actual needs during the granulation process;

[0061] Then the fan can be turned on, and the mixed slurry is transported through the external slurry conveying pipeline for granulation. The slurry enters the overflow seat 309 through the feeding pipe 105 and is diverted and guided. Then, it is sprayed into the tower body 100 through each granulation head 310 and falls into the isolation pipe 201. During the slurry falling inside the isolation pipe 201, part of the solvent it carries will be quickly vaporized, and at the same time, it will be quickly cooled and solidified into spherical particles. Then, it will pass through the bottom partition seat 202 and fall onto the material guide seat 319. In addition, due to the limiting effect of the internal guide seat 320, it will evenly fall onto the external material receiving device through the bottom opening of the material guide seat 319.

[0062] In the above process, the air pump 106 draws in external air and sends the air into the wind drive box 2041, forcing the rotating wheel 206 inside it to rotate under the action of air pressure. Under the transmission action of the toothed disc 209 and the toothed chain 210, the rotating wheel 206 inside the junction box 2042 will also rotate accordingly, forcing the moving pistons 205 inside the two piston boxes 203 to move back and forth synchronously under the limitation of the corresponding half gears 207 and tooth grooves 208;

[0063] As the movable piston 205 inside the circulation box 2032 moves back and forth, the equilibrium state of the refrigerant inside the device is broken. Under the flow limiting effect of the check valve 220, the refrigerant inside the tower body 100 located outside the isolation tube 201 will be drawn into the circulation box 2032 through the extraction tube 212, and the refrigerant inside the circulation box 2032 will be pressed into the junction box 2042 through the explosion-proof tube 211, and the rotating wheel 206 inside the junction box 2042 will form a combined force with the airflow driving force provided by the air pump 106 under the transmission effect of the toothed disc 209 and the toothed chain 210, driving the rotating wheel 206 to rotate more stably and quickly, and the corresponding movable piston 205 will also move back and forth more stably and quickly;

[0064] In this process, a pressure and speed dual amplification structure is formed between the rotating wheel 206, the half gear 207, the tooth groove 208 and the movable piston 205. The structure is briefly described as a pressure-speed amplification structure, that is, the pressure acting on the inclined surface of the rotating wheel 206 will be amplified and drive the movable piston 205 to move back and forth with greater force. During the reciprocating movement of the movable piston 205, the refrigerant will be pressed into the junction box 2042, forcing the inclined surface of the rotating wheel 206 to be subjected to greater pressure, and then rotate at a faster speed, and drive the movable piston 205 to move back and forth faster, thereby infinitely cyclically superimposed until the refrigerant discharged from the pressure-resistant pipe 214 into the compression box 213 reaches the set value;

[0065] In the above process, the hydraulic fluid entering the junction box 2042 will then be pressed into the compression box 213 through the pressure-resistant pipe 214, forcing the pressure inside the compression box 213 to continue to rise. When the pressure is sufficient to overcome the pressure on the other side of the slider 215, that is, when the pressure exceeds the critical pressure of gas-liquid conversion, the hydraulic fluid entering the compression box 213 has been completely liquefied under the pressure, and at this time it will push the slider 215 away. The liquefied hydraulic fluid will enter the aeration seat 217 through the insulation pipe 216, and be evenly discharged into the tower body 100 under the guidance of the aeration seat 217;

[0066] At this time, the gas pressure inside the tower body 100 is lower than the critical gas pressure of liquefaction under the pumping of the extraction pipe 212. In addition, the slurry inside the isolation pipe 201 emits heat, and the liquid refrigerant entering the tower body 100 will quickly vaporize and absorb heat, prompting the slurry inside the isolation pipe 201 to quickly cool and form. Then, the vaporized refrigerant will be pumped into the circulation box 2032 through the extraction pipe 212 again, and the cycle will be repeated, and the gas-liquid conversion will be continuously carried out to extract the heat carried by the slurry and the air, prompting the slurry to cool and form, and at the same time, the extracted heat will be converted into a driving force to drive the rotating wheel 206 to rotate, providing a stable driving force for the granulation work;

[0067] During the reciprocating movement of the movable piston 205 inside the bellows 2031, negative pressure is formed at the exhaust seat 225, forcing the air inside the tower body 100 located at the top of the partition seat 202 to enter the diverter box 221 through the negative pressure pipe 224, and enter the telescopic pipe 223 through the exchange frame 222, and then enter the bellows 2031 through the exhaust pipe 219, and press into the slide pipe 228 through the flow pipe 218, and then enter the heat exchange cylinder 227, and after absorbing the heat released when the refrigerant is liquefied, enter the exhaust pipe 107 through the air supply pipe 323, and enter the top seat 301 under the connection of the sealing threaded ring 303 and the threaded head 304, forcing the driving wheel 305 to rotate, and then enter the filter box 325 through the outlet valve 324, and be discharged into the atmosphere after being purified;

[0068] In the above process, as the air inside the tower body 100 is continuously drawn into the exhaust seat 225, a negative pressure environment is created at the top of the isolation tube 201, so that the air pressure inside the isolation tube 201 decreases from the bottom to the top, causing the slurry falling into the isolation tube 201 to slow down its falling speed under the action of negative pressure, offsetting part of the gravity it receives during its falling process, and expanding the distance between the slurries that fall into the isolation tube 201 successively, making it more layered, and avoiding mutual adhesion when they are not formed. The reduction in air pressure will also force the vaporization point of the solvent in the slurry to be relatively lower, causing part of the solvent to vaporize, and at the same time will prolong the effective cooling time during its falling process, slowing down the drooping feeling of the slurry particles under the action of gravity, and making the slurry more rounded after forming;

[0069] During the rotation of the driving wheel 305, the driving rod 308 is driven to rotate synchronously, forcing each anti-skid wheel 313 to rotate synchronously under the drive of the wear-resistant wheel 314. The flow blocking head 312 is driven by the rotating rod 311 to rotate synchronously, cutting off the slurry overflowing from the granulating head 310. By changing the air pressure borne by the reverse wheel 306, the rotation speed of the driving wheel 305 can be limited, that is, the cutting frequency of the slurry overflowing from the granulating head 310 can be limited. The higher the rotation speed, the higher the frequency, and the smaller the particle size of the slurry after forming, thereby realizing the control of the particle size of the slurry after forming.

[0070] At the same time, the inner guide seat 320, driven by the driving rod 308, drives the scraper rod 321 to rotate, sweeps the bottom end of the partition seat 202, and forces the elastic plate 322 to press the material guide seat 319 to clean the inner wall of the material guide seat 319. In this process, the material guide seat 319 will also be displaced under the pressure of the elastic plate 322 to overcome the elastic force of the spring 317, thereby realizing cyclic screening, which can effectively avoid device blockage and improve the smoothness and stability of material discharge.

[0071] The above is the complete working process of the device. During this process, with the operation of the pressure-speed amplification structure, the hydraulic pressure of the refrigerant will be spontaneously raised to the specified pressure. After the device is working on track, the air pump 106 can be selectively turned off. After the air pump 106 is turned off, the pressure-speed amplification structure will raise the hydraulic pressure of the refrigerant again to compensate for the driving force provided by the air pump 106. At this time, the driving force of the rotating wheel 206 inside the wind-driving box 2041 is completely replaced by the refrigerant hydraulic pressure;

[0072] For the sake of convenience, the air pump 106 may not be started during the entire granulation process. After the slurry enters the isolation tube 201, the heat it emits will also break the equilibrium state of the refrigerant, and the refrigerant will flow spontaneously. The pressure-speed amplification structure will also be started synchronously. The cost is that the granulation effect is poor before the hydraulic pressure of the refrigerant is raised to the set pressure. However, since the hydraulic pressure lifting speed is doubled by the cycle, this process can be selectively ignored.

[0073] The power source in the whole process mainly comes from the heat emitted by the slurry and the heat in the air. Under the pumping of the moving piston 205 inside the bellows 2031, the air inside the tower body 100 and the heat exchange cylinder 227 is in a flowing state, which can equivalently promote the refrigerant to exchange heat with a larger range of external air, thereby improving the effect of extracting heat from the air and making the device more powerful. In most cases, the air pump 106 can be in an inactive state. Only in extremely cold conditions can the airflow driving force provided by the air pump 106 be used to compensate for the driving force of the device. Even if the air pump 106 is not enabled, due to the extreme coldness of the external environment, the granulation effect will only decrease in quality under the external low temperature compensation, but it will not decrease too much.
