[0022] The utility model will be further described below in combination with the drawings and embodiments.

[0023] Please refer to Figures 1-3 Among them, Figure 1 A preferred embodiment of the liquid water-soluble fertilizer cooling pusher provided by the utility model is shown in the main view structure schematic diagram; Figure 2 A preferred embodiment of the liquid water-soluble fertilizer cooling pusher provided by the utility model is shown in the main view structure schematic diagram; Figure 3 A preferred embodiment of the liquid water-soluble fertilizer cooling pusher provided by the utility model is shown in the main view structure schematic diagram; Figure 2 An enlarged structure schematic diagram of the A part shown in the figure.

[0024] The application discloses a liquid water-soluble fertilizer cooling pusher, which comprises a storage tank 1 provided with a feeding hopper 2, a first auger 3 rotatably arranged in the storage tank 1, a rotating motor 4 fixedly arranged on the storage tank 1, an output shaft of the rotating motor 4 being fixedly connected with the first auger 3, a cooling cover 5 fixedly sleeved on the storage tank 1, heat dissipation fins 6 fixedly arranged outside the storage tank 1, the top of the heat dissipation fins 6 extending out of the cooling cover 5, a fan 7 fixedly arranged on the storage tank 1, a connecting pipe 8 fixedly arranged at the air outlet end of the fan 7, one end of the connecting pipe 8 extending into the cooling cover 5 and being correspondingly arranged with the heat dissipation fins 6, an exhaust pipe 9 fixedly arranged on the cooling cover 5, and a circulating mechanism arranged on the storage tank 1 and used for moving the material in circulation for cooling.

[0025] The circulating mechanism comprises a discharge pipe 10, a tee pipe 11, a conveying pipe 12 and a transfer mechanism, the discharge pipe 10 is fixedly installed on the storage tank 1, the tee pipe 11 is fixedly installed on the discharge pipe 10, the conveying pipe 12 is fixedly installed on the tee pipe 11, and the transfer mechanism is arranged at the other end of the conveying pipe 12 and used for transferring the material from the conveying pipe 12 to the feeding hopper 2. The discharge pipe 10 is used for discharging the water-soluble fertilizer material in the storage tank 1 after preliminary cooling treatment, providing a channel for the material to enter the circulating cooling process, and enabling the material to leave the main body of the storage tank 1 for further cooling. The tee pipe 11 connects the discharge pipe 10 and the conveying pipe 12 and plays a role in shunting and turning. On the one hand, it can ensure that the material discharged from the discharge pipe 10 smoothly enters the conveying pipe 12, and on the other hand, the tee structure provides convenience for possible other pipeline connections or function expansion, so that the layout of the whole circulating mechanism is more flexible. The conveying pipe 12 serves as a channel for material transmission and conveys the material from the discharge pipe 10 to the transfer mechanism. The length and direction of the conveying pipe 12 can be reasonably designed according to the actual production site and equipment layout, so as to ensure that the material can be stably and efficiently conveyed and the loss and blocking risk of the material in the conveying process are reduced. The transfer mechanism is a key component for realizing the circulating cooling of the material, which sends the preliminarily cooled material back to the feeding hopper 2 through a specific power and conveying mode, so that the material enters the storage tank 1 again for cooling treatment. In this way, the material can pass through the cooling area multiple times under the action of the circulating mechanism, fully contacts with the cooling environment, greatly improves the cooling effect, guarantees the cooling quality of the water-soluble fertilizer material and ensures the stable performance of the final product.

[0026] The transfer mechanism includes a fixed cylinder 13, a second auger 14, a drive motor 15 and a discharge pipe 16. The fixed cylinder 13 is fixedly installed on the material conveying pipe 12. The second auger 14 is rotatably installed in the fixed cylinder 13. The drive motor 15 is fixedly installed on the fixed cylinder 13. The output shaft of the drive motor 15 is fixedly connected with the second auger 14. The discharge pipe 16 is fixedly installed on the fixed cylinder 13. The open end of the discharge pipe 16 is correspondingly arranged with the feeding hopper 2. The fixed cylinder 13 provides a stable installation and operation space for the second auger 14, plays a supporting and protecting role for the internal components, and at the same time ensures that the material can move along the predetermined path during the conveying process, avoids material leakage or deviation from the conveying direction, and guarantees the stability and reliability of the material conveying. Through rotation, the second auger 14 can effectively push the material conveyed by the material conveying pipe 12 forward along the fixed cylinder 13. Its unique spiral structure can uniformly and continuously convey the material, avoiding the accumulation and blockage of the material, and improving the efficiency of the material conveying. The drive motor 15 provides power for the rotation of the second auger 14, ensuring that the second auger 14 can stably operate at the set rotating speed. By controlling the rotating speed of the drive motor 15, the conveying speed of the material can be flexibly adjusted to meet different production requirements, making the operation of the entire circulating mechanism more flexible and controllable. The role of the discharge pipe 16 is to accurately guide the material conveyed by the second auger 14 into the feeding hopper 2, realizing the circulation of the material.

[0027] The other end of the tee pipe 11 is fixedly installed with a discharge pipe 17, and valves are fixedly installed on the discharge pipe 17, the material conveying pipe 12 and the exhaust pipe 9. The discharge pipe 17 provides another material output channel for the entire cooling pusher in addition to the circulating cooling. After the cooling treatment of the water-soluble fertilizer is completed, when the final product needs to be obtained, the material can pass through the discharge pipe 10 and the tee pipe 11 into the discharge pipe 17, so as to be smoothly discharged from the equipment, facilitating subsequent packaging, storage and other operations, and increasing the functionality of the equipment and the flexibility of the operation. The valve on the discharge pipe 17 can control the opening and closing of the discharge pipe 17. When the material circulating cooling needs to be carried out, the valve is closed to prevent the material from flowing out of the discharge pipe 17, so as to ensure that the material can be fully cooled in the equipment according to the circulating path; when the cooling is completed and the material needs to be discharged, the valve is opened to smoothly discharge the material, so as to realize the controllability of the discharging process. The valve on the material conveying pipe 12 can control the conveying of the material in the material conveying pipe 12. In the initial stage of starting the equipment, maintenance or when the material circulation is not needed, the valve is closed to prevent the material from entering the circulating mechanism, so as to avoid unnecessary energy consumption and equipment wear; in the normal circulating cooling process, the opening of the valve can be adjusted according to the actual production needs, and the valve can also be used to assist in controlling the flow of the material in the circulating system, so as to ensure the stability of the cooling effect. The valve on the exhaust pipe 9 is used to control the discharge of air in the cooling cover 5. During the cooling process, the opening of the valve can be reasonably adjusted to control the air pressure and air flow speed in the cooling cover 5, so as to ensure that the cooling wind blown by the fan 7 can effectively take away the heat on the heat dissipation fins 6, and the cooling efficiency is improved; at the same time, when the equipment stops running or special operations are carried out, the valve is closed to prevent foreign matters such as dust from entering the cooling cover 5, so as to protect the cleanliness and normal operation of the inside of the equipment.

[0028] The heat conducting pipe 18 is wound on the material storage tank 1 and is arranged in the cooling cover 5. The heat conducting pipe 18 is wound on the material storage tank 1 and can be in full contact with the material storage tank 1, so as to quickly and efficiently conduct the heat generated by the water-soluble fertilizer material in the material storage tank 1 out. Since the heat conducting pipe 18 is located in the cooling cover 5, the cooling wind blown by the fan 7 and the heat dissipation fins 6 can assist in heat dissipation, so that the heat on the heat conducting pipe 18 can be quickly taken away by the cooling medium. The cooling wind takes away, so as to greatly improve the heat exchange efficiency and accelerate the cooling speed of the water-soluble fertilizer material.

[0029] The guiding pipe 19 is fixedly installed on the storage tank 1, one end of the guiding pipe 19 is fixedly installed with an exhaust fan 20, the other end of the guiding pipe 19 is fixedly connected with the heat pipe 18, a filter screen 21 is fixedly installed on the guiding pipe 19, and the filter screen 21 is arranged in correspondence with the exhaust fan 20. The guiding pipe 19 plays a role of connecting the heat pipe 18 and the exhaust fan 20, and provides a directional channel for heat conduction and air flow. By guiding the air flow generated by the exhaust fan 20 to the heat pipe 18, the air flow around the heat pipe 18 can be strengthened in a targeted manner, the heat is dissipated from the heat pipe 18 to the external environment, the heat exchange efficiency is further improved, and the cooling speed of the water-soluble fertilizer material is accelerated. Meanwhile, the orderly flow of air in the whole cooling system is ensured, the disorder of air flow is avoided, and the cooling process is more stable and reliable. The exhaust fan 20 can actively generate air flow, and when the exhaust fan 20 is running, the air flow around the guiding pipe 19 and the heat pipe 18 is accelerated. This is helpful to quickly take away the heat on the heat pipe 18 conducted from the storage tank 1, forms a more effective heat dissipation effect, and improves the production efficiency. During the running of the exhaust fan 20, the filter screen 21 can effectively prevent dust, impurities and other particulate matters in the external air from entering the guiding pipe 19, thereby preventing the particulate matters from adhering to the heat pipe 18 and affecting the heat conduction effect.

[0030] The guiding pipe 19 is provided in a horn shape, one end of the guiding pipe 19 is fixedly installed with the exhaust fan 20, and the other end of the guiding pipe 19 is connected with the heat pipe 18. The design of the horn-shaped wider end increases the air collection area. When the exhaust fan 20 is running, air can be sucked from a larger space range, and compared with the guiding pipe in a common shape, more air can be collected. Then, the collected air is effectively guided to the narrower end through the horn shape of the guiding pipe 19 and is concentratedly delivered to the heat pipe 18, so that more sufficient and stronger air flow around the heat pipe 18 can be obtained, thereby greatly improving the heat dissipation effect of the heat pipe 18. According to the principle of fluid mechanics, when air enters a narrower space from a wider space, the flow rate is increased. The horn shape of the guiding pipe 19 makes the flow rate of the air sucked from the exhaust fan 20 faster when entering the narrower end. The fast-flowing air can more quickly take away the heat on the heat pipe 18, further enhances the heat exchange efficiency, accelerates the cooling speed of the water-soluble fertilizer material, and is helpful to improve the production efficiency.

[0031] It is worth noting that the circuits, electronic components and modules involved in the utility model are all prior art, and those skilled in the art can realize them without further description, and the content protected by the utility model does not involve improvement of software and methods.

[0032] The working principle of the liquid water-soluble fertilizer cooling pusher provided by the utility model is as follows:

[0033] When in use, the liquid water-soluble fertilizer to be cooled is put into the storage tank 1 through the feeding hopper 2. At this time, the rotating motor 4 is started to drive the first auger 3 to rotate in the storage tank 1, and the first auger 3 pushes the material to move slowly in the storage tank 1, so that the material is uniformly distributed in the storage tank 1, and the subsequent cooling process is prepared. At the same time, the heat carried by the material itself begins to exchange with the wall of the storage tank 1 during the movement of the material.

[0034] The cooling system starts to work. The fan 7 is started to blow the outside air into the cooling cover 5 through the connecting pipe 8. The cooling cover 5 is fixedly sleeved on the storage tank 1 to form a relatively closed cooling space. The heat dissipation fins 6 installed outside the storage tank 1 increase the contact area with the air, and accelerate the heat transfer from the storage tank 1 to the air.

[0035] The heat conduction pipe 18 wound on the storage tank 1 and located in the cooling cover 5 further conducts the heat of the material in the storage tank 1 out. At this time, the exhaust fan 20 is running. Since the guide pipe 19 is set to be trumpet-shaped, the wider end of the guide pipe 19 is fixed with the exhaust fan 20, and the narrower end is connected with the heat conduction pipe 18. The exhaust fan 20 sucks a large amount of air from the outside, collects and accelerates the air through the trumpet-shaped guide pipe 19, so that the high-speed airflow is concentrated to blow to the heat conduction pipe 18, quickly takes away the heat on the heat conduction pipe 18, and improves the heat exchange efficiency. At the same time, the filter screen 21 installed on the guide pipe 19 blocks the impurities such as dust from the outside to enter, so as to ensure the cleanliness of the inside of the system. The hot air in the cooling cover 5 is discharged through the exhaust pipe 9 to keep the air in the cooling cover 5 circulating, so that the cooling process continues efficiently.

[0036] When the material is preliminarily cooled in the storage tank 1, part of the material is discharged through the discharge pipe 10 and enters the three-way pipe 11. The three-way pipe 11 divides the material to the material conveying pipe 12. At this time, the valve on the material conveying pipe 12 is opened, and the material enters the material conveying pipe 12.

[0037] The driving motor 15 fixed on the fixed cylinder 13 is started to drive the second auger 14 to rotate in the fixed cylinder 13. The second auger 14 pushes the material conveyed by the material conveying pipe 12 forward along the fixed cylinder 13, and finally the material falls into the feeding hopper 2 through the discharging pipe 16 and reenters the storage tank 1 for cooling treatment. Through this circulation mode, the material can pass through the cooling area for multiple times, fully contacts with the cooling environment, and greatly improves the cooling effect.

[0038] When the material is cooled to the required temperature, the valve on the material conveying pipe 12 is closed, and the material circulation is stopped. At the same time, the valve on the discharge pipe 17 is opened, the material enters the discharge pipe 17 through the discharge pipe 10 and the three-way pipe 11, and is smoothly discharged from the equipment, so as to complete the cooling and material pushing process, and then the subsequent packaging, storage and other operations are carried out.
