[0002] Compound fertilizer granulators include equipment such as compound fertilizer pair-roller extrusion granulators, disk granulators or rotary drum granulators. Their main function is to make granular compound fertilizers from various organic and inorganic raw materials through specific technological processes.
[0003] However, in the prior art, during the production process of existing compound fertilizer granulators such as compound fertilizer pair-roller extrusion granulators, due to the extrusion granulation of materials, accompanied by friction and compression, heat will be generated, resulting in the heating of the produced compound fertilizer granules. To avoid the increase in temperature and the easy caking phenomenon between compound fertilizer granules, generally, the produced compound fertilizer granules need to be further cooled. However, compound fertilizer pair-roller extrusion granulators generally lack corresponding measures to cool compound fertilizer granules, resulting in the need to transport the produced compound fertilizer granules to other cooling equipment for cooling, which is rather troublesome. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the drawbacks existing in the prior art: compound fertilizer pair-roller extrusion granulators generally lack corresponding measures to cool compound fertilizer granules, resulting in the need to transport the produced compound fertilizer granules to other cooling equipment for cooling, which is rather troublesome.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a cooling device for a compound fertilizer granulator, including a compound fertilizer pair-roller extrusion granulator. A fixed cylinder is fixed at the support leg of the compound fertilizer pair-roller extrusion granulator, and heat dissipation holes and channel openings are provided on the fixed cylinder. A channel plate is fixed at the feeding port of the compound fertilizer pair-roller extrusion granulator and the channel opening of the fixed cylinder. A barrier net is fixed at the heat dissipation holes of the fixed cylinder, and a closed door is snap-connected to one side opening of the fixed cylinder. Rotating rings are rotatably embedded at both ends of the inner surface of the fixed cylinder, and stirring plates are fixedly connected to the surfaces of the rotating rings. A motor is fixedly connected to one side surface of the fixed cylinder, and the output shaft of the motor penetrates through the fixed cylinder. A fixing plate is fixedly connected to the output shaft of the motor, and one of the fixing plate and the rotating ring is fixedly connected. A connecting plate is fixed at the position below the fixed cylinder at the support leg of the compound fertilizer pair-roller extrusion granulator, and a cooling fan is fixedly connected to the connecting plate.
[0006] As a preferred implementation manner, a pulling handle is fixedly connected to one side surface of the closed door.
[0007] As a preferred embodiment, an electric telescopic rod is fixedly connected through one side surface of the fixed cylinder, and a magnet block is fixedly connected to the telescopic end of the electric telescopic rod. A metal push plate is magnetically adsorbed on one side of the magnet block, and the metal push plate is slidably penetrated and connected with the stirring plate.
[0008] As a preferred embodiment, a clamping block is fixedly connected to one side surface of the metal push plate, and the clamping block is clamped and connected with the output shaft of the motor.
[0009] As a preferred embodiment, a plurality of the stirring plates are arranged at equal intervals around the rotating ring.
[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:
[0011] In the present utility model, the compound fertilizer particles produced by the compound fertilizer roller extrusion granulator directly fall into the fixed cylinder through the channel plate. The cooling fan is turned on to blow and dissipate heat from the compound fertilizer particles in the fixed cylinder through the barrier net on the heat dissipation holes. By turning on the motor and with the help of the connection of the fixed plate, the rotating ring and the stirring plate are driven to rotate.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Embodiment 1
[0020] As Figures 1-4 shown, the present utility model provides a technical solution: a cooling device for a compound fertilizer granulator, including a compound fertilizer double-roll extrusion granulator 1. A fixed cylinder 2 is fixed at the support leg of the compound fertilizer double-roll extrusion granulator 1, and heat dissipation holes and a channel opening are provided on the fixed cylinder 2. A channel plate 3 is fixed at the feeding port of the compound fertilizer double-roll extrusion granulator 1 and the channel opening of the fixed cylinder 2. The feeding port of the compound fertilizer double-roll extrusion granulator 1 and the channel opening of the fixed cylinder 2 are docked through the channel plate 3, so that the compound fertilizer particles produced in the compound fertilizer double-roll extrusion granulator 1 can stably fall into the fixed cylinder 2. A barrier net 4 is fixed at the heat dissipation holes of the fixed cylinder 2. The heat dissipation holes on the fixed cylinder 2 facilitate the heat dissipation of the compound fertilizer particles therein. At the same time, the setting of the barrier net 4 effectively avoids the situation that the compound fertilizer particles scatter outward through the heat dissipation holes of the fixed cylinder 2 while ensuring heat dissipation. One side opening of the fixed cylinder 2 is snap-connected with a closing door 5, and the closing door 5 serves to block the side opening of the fixed cylinder 2. Rotating rings 6 are embedded and rotated at both ends of the inner surface of the fixed cylinder 2, and stirring plates 7 are fixedly connected to the surfaces of the rotating rings 6. By rotating the stirring plates 7, the compound fertilizer particles in the fixed cylinder 2 are stirred, so that they can be more evenly distributed in the fixed cylinder 2, and the heat dissipation rate can be accelerated. A motor 8 is fixedly connected to one side surface of the fixed cylinder 2, and the output shaft of the motor 8 penetrates through the fixed cylinder 2. A fixing plate 9 is fixedly connected to the output shaft of the motor 8, and one of the fixing plate 9 and the rotating ring 6 is fixedly connected. When the motor 8 is started, with the help of the connection of the fixing plate 9, it is convenient to drive the rotating ring 6 and the stirring plates 7 to rotate. A connecting plate is fixed at the support leg of the compound fertilizer double-roll extrusion granulator 1 at a position below the fixed cylinder 2, and a cooling fan 10 is fixedly connected to the connecting plate. When the cooling fan 10 is turned on, the compound fertilizer particles in the fixed cylinder 2 can be blown for heat dissipation through the barrier net 4 on the heat dissipation holes.
[0021] Embodiment 2
[0022] As Figures 1-4As shown in the figure, a pulling handle is fixedly connected to one side surface of the closing door 5. With the help of the pulling handle, it is convenient to pull the closing door 5 to move, so that it is disengaged from the fixed cylinder 2. An electric telescopic rod 11 is fixedly connected through one side surface of the fixed cylinder 2, and a magnet block 12 is fixedly connected to the telescopic end of the electric telescopic rod 11. A metal push plate 13 is magnetically adsorbed on one side of the magnet block 12, and the metal push plate 13 is slidably penetrated and connected with the stirring plate 7. When the compound fertilizer particles are cooled after heat dissipation, by extending the electric telescopic rod 11, the magnet block 12 is adsorbed on the metal push plate 13 and pushes the metal push plate 13 to move towards the opening of the fixed cylinder 2. While the metal push plate 13 is being pushed, the compound fertilizer is also pushed towards the opening of the fixed cylinder 2, facilitating the extraction of the compound fertilizer particles therefrom. After the compound fertilizer particles are taken out, the electric telescopic rod 11 is contracted, and with the help of the connection of the magnet block 12, the metal push plate 13 is driven to move back to its position. After the metal push plate 13 moves back to the fixing plate 9, it is blocked and stops moving. At this time, the electric telescopic rod 11 continues to contract to disconnect the magnet block 12 from the metal push plate 13, effectively avoiding affecting the subsequent rotational movement of the stirring plate 7. A clamping block 14 is fixedly connected to one side surface of the metal push plate 13, and the clamping block 14 is snap-fitted with the output shaft of the motor 8. With the help of the clamping block 14, the stability of the metal push plate 13 after returning to its position is improved, effectively avoiding the accidental movement thereof from affecting the normal heat dissipation and cooling of the compound fertilizer particles on one side thereof. The number of stirring plates 7 is arranged at equal intervals around the rotating ring 6. By increasing the number of stirring plates 7, the stirring effect on the compound fertilizer particles can be effectively improved.
[0023] Working principle:
[0024] As Figures 1-4 shown, when the present utility model is in use, the compound fertilizer roller extrusion granulator 1 is started to produce compound fertilizer particles normally. The compound fertilizer particles produced in the compound fertilizer roller extrusion granulator 1 will directly fall into the fixed cylinder 2 through the channel plate 3. Then the user turns on the cooling fan 10, and the wind blown by the cooling fan 10 will directly blow the compound fertilizer particles in the fixed cylinder 2 through the barrier net 4 for heat dissipation. Due to the continuous production of the compound fertilizer roller extrusion granulator 1, the compound fertilizer particles in the fixed cylinder 2 will become more and more. At this time, in order to ensure the efficiency of heat dissipation and cooling, the user needs to turn on the motor 8 to make the output shaft of the motor 8 start to rotate. The rotation of the output shaft of the motor 8 drives the rotation of the fixing plate 9, and the rotation of the fixing plate 9 drives the rotation of the rotating ring 6, thereby driving the rotation of the stirring plate 7. The rotating stirring plate 7 stirs the compound fertilizer particles in the fixed cylinder 2, so that they can be more evenly distributed in the fixed cylinder 2, accelerating the heat dissipation rate.
[0025] After the heat dissipation and cooling are completed, turn off the motor 8 and the cooling fan 10. Manually pull the pulling handle on the closing door 5 to drive the movement of the closing door 5 so that it is disengaged from the fixed cylinder 2. At this time, extend the electric telescopic rod 11 so that the magnet block 12 adsorbs on the metal push plate 13 and pushes the metal push plate 13 towards the opening of the fixed cylinder 2. Then, the clamping block 14 on the metal push plate 13 will be disengaged from the output shaft of the motor 8. While the metal push plate 13 is being pushed, the compound fertilizer is also pushed towards the opening of the fixed cylinder 2, which facilitates the user to take out the compound fertilizer particles from the fixed cylinder 2.
[0026] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
