Abstract
Description
Technical Field
[0001] This utility model relates to the field of compound fertilizer production and processing technology, specifically to a cooling device for compound fertilizer production. Background Technology
[0002] Compound fertilizer is a type of chemical fertilizer composed of multiple nutrients, typically including nitrogen, phosphorus, potassium, and other elements. It provides crops with a variety of nutrients needed for growth, helping to increase crop yields and improve soil fertility. Due to its combination of various nutrients, compound fertilizer is widely used in agricultural production.
[0003] In compound fertilizer production, heat-treated compound fertilizer granules typically need to be cooled to lower their temperature. Cooling these granules requires a cooling device, but existing devices often have low efficiency, resulting in ineffective cooling. Furthermore, current practices typically involve feeding large quantities of material into the cooling device, which often leads to material piling up and hinders cooling efficiency. Utility Model Content
[0004] To address the existing technical problems, this utility model provides a cooling device for compound fertilizer production, including a cooling box with a feed inlet at the top.
[0005] The cooling box is provided with a first conveyor belt, a second conveyor belt and a third conveyor belt arranged from top to bottom, with the input end of the first conveyor belt located directly below the feed inlet;
[0006] The output end of the first conveyor belt is located above the input end of the second conveyor belt, the output end of the second conveyor belt is located above the input end of the third conveyor belt, and the output end of the third conveyor belt passes through one side inner wall of the cooling box and extends to the outside of the cooling box; the first conveyor belt, the second conveyor belt and the third conveyor belt are all tensioned on two drive rollers, and the two ends of the drive rollers are hinged to two corresponding bearing seats.
[0007] The cooling box has several ventilation holes on its front and rear inner walls, and a cooling mechanism for cooling materials is fixedly connected to the inner walls of the ventilation holes.
[0008] Above the input ends of the first, second, and third conveyor belts, a dispersion and spreading mechanism for dispersing materials is provided. The dispersion and spreading mechanism includes an inverted U-shaped mounting block. Several first dispersion plates are fixedly installed on the bottom of the horizontal section of the mounting block. A hollow fixing block is provided between two adjacent first dispersion plates.

The other end of the rotating shaft passes through the bottom of the fixing block and is fixedly connected to a rotating disk. A rotating rod is fixedly connected to one side of the rotating disk. Several second dispersion plates are fixedly installed at the bottom of the rotating rod.
[0009] A further embodiment is that the interior of the cooling box is provided with a first mounting plate and a second mounting plate, and the first mounting plate and the second mounting plate are respectively fixedly connected to one side wall of the cooling box;
[0010] The first conveyor belt is fixedly mounted on the first mounting plate, the second conveyor belt is fixedly mounted on the second mounting plate, and the third conveyor belt is fixedly mounted on the inner bottom wall of the cooling box.
[0011] A further embodiment is that the cooling mechanism includes a fixed frame, a fixed bracket is fixedly connected to the inner wall of the fixed frame, a rotating motor is fixedly connected to the inner cavity of the fixed bracket, and a fan is fixedly connected to the power output shaft of the rotating motor.

[0017] The beneficial effects of this utility model are:
[0018] This invention features three parallel conveyor belts at different heights inside a cooling box, along with several cooling mechanisms. The material is transported within the cooling box for a certain period, and the cooling mechanisms blow cold air through the box, accelerating the flow of gas and ensuring sufficient contact between the cold air and the material.

Detailed Implementation
[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] like Figure 1-5As shown, one embodiment of this utility model discloses a cooling device for compound fertilizer production, including a cooling box 1, with a feed inlet 10 provided on the top of the cooling box 1;
[0028] The cooling box 1 is provided with a first conveyor belt 11, a second conveyor belt 12 and a third conveyor belt 13 arranged from top to bottom. The input end of the first conveyor belt 11 is located directly below the feed inlet 10.
[0029] The output end of the first conveyor belt 11 is located above the input end of the second conveyor belt 12, the output end of the second conveyor belt 12 is located above the input end of the third conveyor belt 13, and the output end of the third conveyor belt 13 passes through one side inner wall of the cooling box 1 and extends to the outside of the cooling box 1; the first conveyor belt 11, the second conveyor belt 12 and the third conveyor belt 13 are all tensioned on two drive rollers 14, and the two ends of the drive rollers 14 are hinged to two corresponding bearing seats 15; the front inner wall and the rear inner wall of the cooling box 1 are provided with a number of ventilation holes 16, and the inner walls of the ventilation holes 16 are all fixedly connected with cooling mechanisms for cooling materials;
[0030] This embodiment, through the above-described configuration, allows the material to be cooled to be fed into the cooling box through the inlet and fall onto the input end of the first conveyor belt. The first, second, and third conveyor belts are then activated. The first conveyor belt transports the material from its input end to its output end and then outputs it, causing the material to fall onto the input end of the second conveyor belt. The second conveyor belt transports the material from its input end to its output end and then outputs it, causing the material to fall onto the input end of the third conveyor belt. The third conveyor belt transports the material from its input end to its output end and outputs it from the other end of the cooling box. During the material's transport within the cooling box, several cooling mechanisms are activated, causing them to blow cold air into the cooling box. This accelerates the airflow within the cooling box, ensuring sufficient contact between the cold air and the material, achieving rapid cooling and improving cooling efficiency.
[0031] Above the input ends of the first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13, there are dispersion and spreading mechanisms for dispersing materials. The dispersion and spreading mechanism includes an inverted U-shaped mounting block 20. Several first dispersion plates 21 are fixedly installed on the bottom of the horizontal section of the mounting block 20. A hollow fixing block 22 is installed between two adjacent first dispersion plates 21. The top of the fixing block 22 is fixed to the top wall of the horizontal section of the mounting block 20. A drive motor 23 is fixedly installed on the top wall inside the fixing block 22. The power output shaft of the drive motor 23 is connected to the rotating shaft 24. The other end of the rotating shaft 24 passes through the bottom of the fixing block 22 and is fixedly connected to the rotating disk 25. A rotating rod 26 is fixedly connected to one side of the rotating disk 25. Several second dispersion plates 27 are fixedly installed at the bottom of the rotating rod 26.
[0032] In this embodiment, the above-described configuration ensures that the material passes through the dispersing and spreading mechanism during its transport on the first, second, and third conveyor belts. Specifically, the material enters the dispersing and spreading mechanism through several channels between adjacent first dispersing plates, where it is initially dispersed by the plates. Then, by activating the drive motor, the power output shaft rotates, causing a rotating shaft to rotate, which in turn rotates a rotating disk. This rotation of the disk, in turn, rotates a rotating rod, causing several second dispersing plates to rotate between the first dispersing plates. This secondary dispersion of the material as it passes through the channels between adjacent first dispersing plates ensures thorough dispersion. Finally, a cooling mechanism further cools the dispersed material, enhancing the cooling effect.
[0033] In this embodiment, several first dispersion plates 21 are equidistantly distributed at the bottom of the horizontal section of the mounting block 20.
[0034] This embodiment, through the above-described configuration, enables the material to be dispersed repeatedly using several first dispersion plates.
[0035] In this embodiment, the length of the rotating rod 26 is slightly less than half the distance between two adjacent first dispersion plates 21.
[0036] In this embodiment, by setting the rotating rod of the above-mentioned length, the radius of the rotating rod's rotation around the axis is maximized, thereby enabling the material located between the two first dispersion plates to be dispersed within the maximum range.
[0037] In this embodiment, several second dispersion plates 27 are equidistantly distributed at the bottom of the rotating rod 26.
[0038] This embodiment enables secondary dispersion of materials using several second dispersion plates through the above-described configuration.
[0039] In this embodiment, a first mounting plate 17 and a second mounting plate 18 are provided inside the cooling box 1, and the first mounting plate 17 and the second mounting plate 18 are respectively fixedly connected to one side wall of the cooling box 1.
[0040] The first conveyor belt 11 is fixedly mounted on the first mounting plate 17, the second conveyor belt 12 is fixedly mounted on the second mounting plate 18, and the third conveyor belt 13 is fixedly mounted on the inner bottom wall of the cooling box 1.
[0041] This embodiment enables the fixed installation of the first conveyor belt, the second conveyor belt, and the third conveyor belt through the above-described settings.
[0042] In this embodiment, the cooling mechanism includes a fixed frame 30, a fixed bracket 31 is fixedly connected to the inner wall of the fixed frame 30, a rotating motor 32 is fixedly connected to the inner cavity of the fixed bracket 31, and a fan 33 is fixedly connected to the power output shaft of the rotating motor 32.
[0043] This embodiment, through the above-described configuration, enables the cooling mechanism to blow air into the cooling box, accelerating the flow of gas inside the cooling box and achieving rapid cooling of the material.
[0044] In this embodiment, several cooling mechanisms are arranged in three rows and are respectively positioned above the first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13.
[0045] This embodiment, through the above-described configuration, enables cold air to be blown directly onto the material on the conveyor belt, thereby accelerating the cooling of the material.
[0046] In this embodiment, baffles 4 are fixedly provided on both sides of the first conveyor belt 11, the second conveyor belt 12 and the third conveyor belt 13, and ventilation nets 40 are provided on the sides of all the baffles 4 along their length direction.
[0047] This embodiment, through the above-described configuration, allows materials to be prevented from sliding off the conveyor belt during transport by setting baffles. The ventilation mesh allows cold air from the cooling mechanism to reach the surface of the material, thereby cooling it.
[0048] In this embodiment, a first guide plate 50 is provided between the output end of the first conveyor belt 11 and the input end of the second conveyor belt 12, and the first guide plate 50 is fixedly disposed on the inner side wall of the cooling box 1. A second guide plate 51 is provided between the output end of the second conveyor belt 12 and the input end of the third conveyor belt 13, and the second guide plate 51 is fixedly disposed on the other inner side wall of the cooling box 1.
[0049] This embodiment, through the above-described configuration, enables materials to smoothly fall from the first conveyor belt onto the second conveyor belt and from the second conveyor belt onto the third conveyor belt via the first and second guide plates.
[0050] Finally, it should be noted that the above description only details specific embodiments of this utility model. However, this utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to this utility model by those skilled in the art are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
