Description

Technical Field

[0001] This utility model relates to the field of diammonium phosphate production technology, specifically to a uniformly dispersed cooling device for diammonium phosphate. Background Technology

[0002] Diammonium phosphate (DAP) is a compound fertilizer containing both nitrogen and phosphorus nutrients, suitable for various crops and soils, especially nitrogen-loving and phosphorus-demanding crops. It can be used as a base fertilizer or top dressing and should be applied deeply. During the production of DAP, the granules formed after spray granulation need to be dried. This drying process is generally carried out in a dryer. After drying, the DAP is at a relatively high temperature and needs to be cooled before packaging.

[0003] Currently used cooling devices often result in excessively thick material build-up during cooling, hindering effective cooling of the internal materials. Furthermore, some materials crystallize and adhere, forming large lumps that cool slowly within. This results in inefficient cooling and low overall cooling efficiency. Therefore, improving existing cooling equipment and designing a novel diammonium phosphate uniform dispersion cooling device to address these technical deficiencies and enhance the overall practicality of the cooling system is of paramount importance. Utility Model Content

[0004] The purpose of this invention is to provide a uniformly dispersed cooling device for diammonium phosphate, which solves the problems of excessively thick material accumulation during cooling, poor internal material cooling, and some material crystallizing and agglomerating into large lumps, resulting in slow cooling of the material inside the lumps and thus slow cooling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A uniform dispersion and cooling device for diammonium phosphate includes a workbench body, a crusher fixedly connected to the top of the workbench body, a hopper fixedly connected to the front end of the crusher, a cooling tank fixedly connected to the front end of the workbench body, a first cooling component inside the cooling tank, a discharge pipe fixedly connected to the bottom of the cooling tank, and a second cooling component outside the discharge pipe. The first cooling assembly is used to beat and cool the material introduced into the cooling tank. The first cooling assembly includes a rotating rod rotatably connected to the inside of the cooling tank. Rotating frames are fixedly connected to the bottom of the rotating rod around its four sides. Multiple sets of sleeves are fixedly connected to the outside of the rotating rod. A moving rod is slidably connected to the end of the sleeve away from the rotating frame. A rotating plate is fixedly connected to the end of the moving rod away from the sleeve. The second cooling component is used to further cool the material.

[0006] As a preferred embodiment of this utility model, a connecting column is fixedly connected to the middle of the interior of the cooling tank and to the inner side of multiple sets of rotating frames. The rotating frame and the connecting column are slidably connected, and the rotating rod is rotatably connected to the connecting column.

[0007] As a preferred embodiment of this utility model, a guide column is fixedly connected to the top of the interior of the cooling tank. The guide column has a conical structure design. A connecting shell is fixedly connected to the front end of the hopper. The hopper is connected to the cooling tank through the connecting shell.

[0008] As a preferred embodiment of this utility model, a compression spring is fixedly connected inside the sleeve, the moving rod extends into the inside of the sleeve and is fixedly connected to the compression spring, cavities are opened inside the rotating rod and the rotating frame, and spray holes are opened on both sides inside the sleeve, and the spray holes are interconnected with the cavities.

[0009] As a preferred embodiment of this utility model, the rotating rod extends to the top of the connecting shell and is fixedly connected to a first synchronous pulley. A synchronous belt is provided on the outer side of the first synchronous pulley, and a second synchronous pulley is provided at the end of the synchronous belt away from the first synchronous pulley. The drive end of a drive motor is fixedly connected inside the second synchronous pulley, and a conveying pipe is rotatably connected to the top of the first synchronous pulley.

[0010] As a preferred embodiment of this utility model, the second cooling assembly includes a spiral tube fixedly connected to the outside of the discharge pipe, a water storage tank fixedly connected to the end of the spiral tube away from the discharge pipe, a water pump fixedly connected to the outside of the water storage tank, and the water pump fixedly connected to the spiral tube.

[0011] As a preferred embodiment of this utility model, a semiconductor cooling chip is fixedly connected inside the water storage tank, and a heat sink is fixedly connected to the outside of the water storage tank extending from the semiconductor cooling chip.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, through the design of the first cooling component, the rotating plate beats the material during rotation to prevent clumping and promote material dispersion. The rotating plate is like a set of brooms or beaters, constantly breaking up and flattening the falling diammonium phosphate material that may clump, preventing it from accumulating too thickly or forming dead zones in the tank. This greatly increases the surface area and fluidity of the material. The cold air is sprayed from the moving, material-dispersing component, which can dynamically, fully, and without dead angles mix with the material, avoiding local overheating or uneven cooling that occurs in traditional static cooling, and improving the stability of the finished product quality. The three major functions of stirring, crushing, and cooling are integrated into one rotating body, which has a compact structure and does not require additional stirring motors and complex air duct systems, saving space and manufacturing costs.

[0013] 2. In this utility model, through the design of the second cooling component, the water pump pumps the cooling water in the water storage tank into the spiral tube to indirectly cool the material in the discharge pipe. The semiconductor refrigeration chip continuously cools the water in the water storage tank to ensure that the cooling water is always at a low temperature. As the second cooling barrier, it is responsible for cooling the material from a higher temperature to close to the ambient temperature to meet the packaging process requirements.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figures 1-4 This utility model provides a technical solution: A uniformly dispersed cooling device for diammonium phosphate includes a workbench body 1, a crusher 2 fixedly connected to the top of the workbench body 1, a hopper 3 fixedly connected to the front end of the crusher 2, a cooling tank 4 fixedly connected to the front end of the workbench body 1, a first cooling component 5 provided inside the cooling tank 4, a discharge pipe 6 fixedly connected to the bottom of the cooling tank 4, and a second cooling component 7 provided outside the discharge pipe 6. The first cooling component 5 is used to beat and cool the material introduced into the cooling tank 4. The first cooling component 5 includes a rotating rod 8 rotatably connected to the inside of the cooling tank 4. Rotating frames 9 are fixedly connected to the bottom of the rotating rod 8 around its perimeter. Multiple sets of sleeves 10 are fixedly connected to the outside of the rotating rod 8. A moving rod 11 is slidably connected to the end of the sleeve 10 away from the rotating frame 9. A rotating plate 12 is fixedly connected to the end of the moving rod 11 away from the sleeve 10. The second cooling component 7 is used for further cooling of the material.

[0018] Furthermore, a connecting column 13 is fixedly connected to the middle of the interior of the cooling tank 4 and to the inner side of multiple sets of rotating frames 9. The rotating frames 9 and the connecting column 13 are slidably connected. The rotating rod 8 is rotatably connected to the connecting column 13. A guide column 14 is fixedly connected to the top of the interior of the cooling tank 4. The guide column 14 has a conical structure design. A connecting shell 15 is fixedly connected to the front end of the feeding hopper 3. The feeding hopper 3 is connected to the cooling tank 4 through the connecting shell 15. When the material is crushed, it is introduced into the interior of the connecting shell 15 through the feeding hopper 3, so that the material is introduced into the interior of the cooling tank 4. When the material is introduced into the interior of the cooling tank 4, the guide column 14 can guide and disperse the material, and introduce the material into the interior of the cooling tank 4 and to the outside of the connecting column 13.

[0019] Secondly, a compression spring 16 is fixedly connected inside the sleeve 10, and the moving rod 11 extends into the inside of the sleeve 10 and is fixedly connected to the compression spring 16. The rotating rod 8 and the rotating frame 9 are both provided with cavities 17. Spray holes 18 are provided on both sides inside the sleeve 10. The spray holes 18 are connected to the cavities 17. The moving rod 11 is moved by the compression spring 16, so that the rotating plate 12 is moved and fits against the inner wall of the cooling tank 4.

[0020] Furthermore, a first synchronous pulley 19 is fixedly connected to the top of the connecting shell 15 via the rotating rod 8. A synchronous belt 20 is provided on the outer side of the first synchronous pulley 19, and a second synchronous pulley 21 is provided at the end of the synchronous belt 20 away from the first synchronous pulley 19. The drive end of the drive motor 22 is fixedly connected inside the second synchronous pulley 21. A conveying pipe 23 is rotatably connected to the top of the first synchronous pulley 19, connecting the conveying pipe 23 to the cooling device, so that the cold air generated by the cooling device can be introduced into the interior of the conveying pipe 23. The cooling device is a mature existing technology, therefore, in this embodiment, further... The process is described in more detail: the drive motor 22 is started to drive the rotating rod 8 to rotate, causing the rotating frame 9 to move in an arc around the rotating rod 8 as the center. This causes multiple sets of sleeves 10 to move in an arc, allowing the rotating rod 8 to drive the rotating plate 12 to move in an arc, thus patting the material and breaking it up. At the same time, cold air is introduced into the interior of the rotating rod 8 through the conveying pipe 23, allowing the cold air to enter the interior of the cavity 17, and then into the interior of the spray hole 18. The cold air comes into contact with the material through the spray hole 18, thus cooling the material.

[0021] Furthermore, the second cooling assembly 7 includes a spiral tube 24 fixedly connected to the outside of the discharge pipe 6. A water storage tank 25 is fixedly connected to the end of the spiral tube 24 away from the discharge pipe 6. A water pump 26 is fixedly connected to the outside of the water storage tank 25. The water pump 26 is fixedly connected to the spiral tube 24. A semiconductor cooling chip is fixedly connected inside the water storage tank 25. A heat sink 27 is fixedly connected to the outside of the semiconductor cooling chip. A control valve is fixedly connected to the end of the discharge pipe 6 near the cooling tank 4. Opening the control valve allows the material inside the cooling tank 4 to be introduced into the discharge pipe 6. The semiconductor cooling chip is activated, and the cooling end of the semiconductor cooling chip cools the water inside the water storage tank 25. The heating end dissipates heat through the heat sink 27 to prevent affecting the operation of the cooling end. The water pump 26 is activated to introduce cooling water into the spiral tube 24. The spiral tube 24 can cool the discharge pipe 6, thereby further cooling the material.

[0022] In this embodiment, the specific implementation scenario is as follows: In actual use, the material is introduced into the crusher 2 for crushing, then into the hopper 3, and finally into the connecting shell 15, allowing the material to enter the cooling tank 4. While the material is entering the cooling tank 4, the guide column 14 guides and disperses the material, ensuring it is positioned outside the connecting column 13. The drive motor 22 is then activated to rotate the rotating rod 8, causing the rotating frame 9 to move in an arc around the rotating rod 8. This arc-shaped movement of the multiple sleeves 10 further drives the rotating rod 8 to move the rotating plate 12, which in turn beats and disperses the material. Simultaneously, the material is conveyed through the conveying pipe 2... 3. Cold air is introduced into the rotating rod 8, allowing it to enter the cavity 17 and then the nozzle 18. The cold air comes into contact with the material through the nozzle 18, thus cooling the material. The control valve is opened, allowing the material inside the cooling tank 4 to enter the discharge pipe 6. The semiconductor refrigeration chip is activated, cooling the water in the water storage tank 25 through its cooling end. The heating end dissipates heat through the heat sink 27 to prevent interference with the operation of the cooling end. The water pump 26 is activated to introduce cooling water into the spiral tube 24, which cools the discharge pipe 6, further cooling the material. Compared with existing cooling equipment, this invention improves the overall practicality of the cooling equipment through its design.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
