Description

Technical Field

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

[0002] In fertilizer production, the cooling process is a crucial step in ensuring product quality. Fertilizer granules that have just undergone granulation and drying are at a high temperature. If they are packaged or stored directly, the residual heat can cause the granules to stick together and clump, which not only damages the physical properties of the fertilizer but may also affect its nutrient stability. At the same time, proper cooling treatment can reduce the brittleness of fertilizer granules, reduce breakage rates during transportation and use, and enhance the product's commercial value.

[0003] Currently, most commonly used fertilizer cooling devices have a fixed cavity structure, and the size of the cooling space is difficult to adjust flexibly according to actual production needs. When the processing volume is small, an excessively large cooling space will reduce the utilization rate of the cooling medium (such as cold air), requiring more energy to achieve the expected cooling effect, resulting in energy waste. When the processing volume is large, the fixed space may affect the cooling uniformity due to material accumulation, making it difficult to balance cooling efficiency and energy economy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a cooling device for fertilizer production, comprising:

[0023] The shell 1 has multiple support legs on both sides, which give the shell 1 a certain height so that the cooled fertilizer can be discharged from the bottom of the shell 1. The bottom of the shell 1 is arc-shaped and the top is rectangular.

[0024] Motor 2 is mounted on the side wall of housing 1. A through hole is provided on the side wall of housing 1, and the output shaft of motor 2 passes through the through hole.

[0025] A rotating shaft 3 is rotatably mounted on the housing 1. One end of the rotating shaft 3 is connected to the output shaft of the motor 2. Multiple grooves 4 are provided on the rotating shaft 3. Material feeding plates 5 are provided on the rotating shaft 3 and on both sides of the grooves 4. The multiple grooves 4 are equally spaced. When the rotating shaft 3 drives the material feeding plates 5 to rotate, the material feeding plates 5 can slide and connect with the bottom arc-shaped inner wall of the housing 1.

[0026] Multiple first baffle plates 6 are set on the bottom wall of the housing 1 and correspond to the positions of multiple grooves 4. The top of the first baffle plate 6 is arc-shaped and rotatably connected to the groove 4 part of the rotating shaft 3.

[0027] Multiple feed pipes 9 are connected and arranged at the top of the housing 1 and above multiple feed plates 5. Fertilizer is conveyed into the housing 1 through the feed pipes 9. During the cooling process, the feed pipes 9 can discharge hot steam to the outside.

[0028] Multiple sealing doors 10 are provided at the bottom of the housing 1 and are closable, corresponding to the positions of multiple material feeding plates 5. When the sealing doors 10 are opened, fertilizer can be discharged from the housing.

[0029] Multiple air inlet pipes 11 are connected to the housing 1 and correspond to the positions of multiple material feeding plates 5. The number of air inlet pipes 11 corresponds to the number of material feeding plates 5. Cold air for cooling fertilizer enters the housing 1 through the air inlet pipes 11.

[0030] Multiple mounting slots are provided on the top of the housing 1 above the multiple grooves 4. A sealing plate 8 or a second baffle plate 7 is inserted into the mounting slot. The first baffle plate 6 and the second baffle plate 7 are used to separate the fertilizer. When the sealing plate 8 is inserted into the mounting slot, it can prevent the fertilizer from overflowing from the mounting slot when the fertilizer is stirred by the feeding plate. The second baffle plate 7 has a slot. When the second baffle plate 7 is located in the mounting slot, the rotating shaft 3 and the first baffle plate 6 can be located in the slot, so that the first baffle plate 6 and the second baffle plate 7 separate the interior of the housing 1.

[0031] As an embodiment of this utility model, a threaded rod 12 is threadedly connected to the housing 1, and a locking block 13 is rotatably connected to the threaded rod 12. The threaded rod 12 can drive the locking block 13 to fix one side of the sealing door 10, and the other side of the sealing door 10 is rotatably connected to the housing 1.

[0032] In this embodiment, when it is necessary to fix the sealing door 10, the operator screws the threaded rod 12, and the threaded rod 12 causes the locking block 13 to abut against the sealing door 10 to fix the sealing door 10.

[0033] As an embodiment of this utility model, a stepped groove is provided in the mounting groove, and protrusions are provided on both sides of the top of the sealing plate 8 and the second baffle plate 7, and the protrusions are provided in the stepped groove.

[0034] In this embodiment, when the protrusion of the sealing plate 8 or the second baffle plate 7 is disposed in the stepped groove, it can effectively prevent the sealing plate 8 or the second baffle plate 7 from shifting on the housing 1.

[0035] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0036] The working principle and usage process of this utility model are as follows: During use, the second baffle plate 7 is inserted into the corresponding mounting slot according to the quantity of fertilizer to be cooled. Sealing plates 8 are inserted into the remaining mounting slots. The fertilizer to be cooled is fed into the housing 1 through the feed pipe 9. The motor 2 is started, driving the rotating shaft 3 to rotate. The rotating shaft 3 drives multiple material-pulling plates 5 to rotate, causing the fertilizer to tumble within the housing 1. Cold air is supplied through the air inlet pipe 11 containing the fertilizer. The air generated during fertilizer cooling is discharged from the feed pipe 9. After the fertilizer has been sufficiently cooled, the motor 2 is started, and the sealing door 10 at the bottom of the housing 1 is opened to discharge the fertilizer. This utility model adjusts the size of the fertilizer cooling chamber by inserting the second baffle plate 7 into different mounting slots, thereby matching the quantity of fertilizer with the cooling space, reducing the waste of cooling medium, and improving energy efficiency.

[0037] 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.
