Description

Technical Field

[0001] This utility model belongs to the field of compound fertilizer production technology, and in particular relates to a cooling machine for high-tower compound fertilizer production. Background Technology

[0002] High-tower compound fertilizer is a urea and potassium fertilizer melt granulation method. It utilizes the principle of rapid crystallization after urea melts. Ammonium phosphate is heated and metered, along with urea and potassium slurry, and then sprayed into a high tower through nozzles to produce compound fertilizer granules. This fertilizer is characterized by uniform and smooth granules, melting pores, and non-caking properties. In terms of appearance, internal quality, and crop yield increase, it far surpasses ordinary compound fertilizers sold on the market. During the production process, high-tower compound fertilizer requires high-temperature drying of the formed compound fertilizer. However, directly removing it after drying can easily cause the fertilizer to react with air. Therefore, the dried high-tower compound fertilizer needs to be cooled by a cooler before further processing to ensure product quality. However, it still has the following drawbacks in practical use:

[0003] 1. Utility model disclosure CN204923988U discloses a cooler for compound fertilizer. A sleeve is fitted around the outside of the drying cylinder, and a water inlet is provided at the upper part of the sleeve. A spraying device is installed inside the drying cylinder. The spraying device includes a water distribution pipe, connecting pipes, and nozzles. The water distribution pipe is connected to the water inlet, and several connecting pipes are provided on the water distribution pipe. Each connecting pipe is connected to a double-layer nozzle. The double-layer nozzle includes a water inlet pipe, a main body plate, and a spray head. The water inlet pipe is connected to the connecting pipe... The pipes are connected, and the main body is fitted onto the water inlet pipe. A rotary sealing component is provided at the connection between the main body and the water inlet pipe. The spray head includes an upper spray component and a lower spray component. A rubber clamp is fitted onto the outside of the water inlet pipe. When the compound fertilizer passes through the cooler, the cylinder is often cooled by sprayed cold water, which further cools the air inside the cylinder and finally cools the compound fertilizer. However, it takes a certain amount of time for the cold water to cool the cylinder and then cool the air inside the cylinder, making it difficult to quickly cool the fertilizer inside the cylinder.

[0004] 2. When cooling large quantities of compound fertilizer, sealed coolers are usually large in size to ensure they can hold a large amount of compound fertilizer. However, large coolers will occupy a lot of space in the production workshop, and the cooling time required for large quantities of compound fertilizer is too long, reducing production efficiency. On the other hand, non-sealed coolers are often long in length to ensure sufficient cooling time for compound fertilizer, which is not convenient for layout in the production workshop. In addition, non-sealed coolers are prone to introducing outside air during use, which may affect product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling machine for high-tower compound fertilizer production. By cooling the material conveying tank and the cold water tank, it solves the problem that the cooling machine cools the cylinder body by cooling the cold water and then the air inside the cylinder, and finally cools the compound fertilizer. The cooling efficiency is low. Sealed cooling machines are usually large in size, occupying a lot of space in the production workshop, and the cooling time required for a large amount of compound fertilizer is too long. Non-sealed cooling machines are often long, which is not convenient for layout in the production workshop, and they are prone to introducing outside air during use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a cooling machine for producing high-tower compound fertilizer, comprising a cooling conveying tank and a cold water tank. A conveying motor is snapped and fixed at one end of the cooling conveying tank, a spiral conveying assembly is attached inside the cooling conveying tank, a cold water tank is snapped and fixed to the outer circumference of the cooling conveying tank, an air pump is snapped and fixed at one end of the cold water tank, and a spiral cooling pipe is provided inside the cold water tank, the spiral cooling pipe being sleeved on the outer circumference of the cooling conveying tank.

[0008] The conveying motor drives the screw conveyor assembly to rotate, transporting the high-temperature compound fertilizer poured into the cooling conveyor hopper. Cold water is pumped into the cold water tank to cool the surface of the cooling conveyor hopper, further cooling the air and compound fertilizer inside. Simultaneously, air is drawn from the cooling conveyor hopper through a sludge extraction system, and the extracted high-temperature air is rapidly cooled through the screw cooling pipe before entering the other end of the cooling conveyor hopper. This circulating air further cools the compound fertilizer, improving cooling efficiency. The airflow direction is opposite to the conveying direction of the screw conveyor assembly, extending the cooling time of the compound fertilizer in the cooler. This allows the cooler to be shortened during production, improving space utilization. At the same time, the cold air is quickly drawn to the slow-flowing discharge pipe end of the cooling conveyor hopper, resulting in relatively high air pressure at the discharge end, preventing the entry of external cold air and avoiding contamination of the compound fertilizer, thus ensuring product quality.

[0009] Furthermore, a slow-flow feed pipe is welded through the top of one side of the cooling feed tank, and a slow-flow discharge pipe is welded through the bottom of the other side of the cooling feed tank. The slow-flow feed pipe and the slow-flow discharge pipe are located at both ends of the cold water tank, respectively.

[0010] The slow-flow feed pipe slows down the flow of fertilizer entering the cooling conveyor and the air being drawn in, preventing compound fertilizer from entering the spiral cooling pipe. The slow-flow discharge pipe slows down the flow of cold air, preventing a large amount of cold air from being discharged through the slow-flow discharge pipe under air pressure.

[0011] Furthermore, a drive rod is rotatably connected to one end of the conveying motor, the spiral conveying assembly is fixed to the outer circumference of the drive rod, a vent hole is provided through one side of the spiral conveying assembly, and the drive rod is inserted through and connected to one end of the cooling conveying barrel.

[0012] The conveying motor drives the drive rod to rotate, which in turn drives the screw conveyor assembly to rotate, conveying the compound fertilizer poured into the cooling conveyor bucket. The vent allows cold air to pass directly through one side of the screw conveyor assembly, ensuring the amount of cold air passing through and improving the cooling speed of the fertilizer.

[0013] Furthermore, a support frame is snapped and fixed to the bottom of the outer periphery of the cold water tank, an inlet pipe is welded through the bottom of one side of the cold water tank, and a drain pipe is welded through the top of the other side of the cold water tank.

[0014] A large amount of cold water is introduced into the cold water tank through the inlet pipe, and the surface of the cooling conveying tank is cooled by the cold water. This further cools the air and compound fertilizer inside the cooling conveying tank, and the heated water is discharged through the drain pipe.

[0015] Furthermore, an exhaust pipe is inserted through and snapped onto the bottom of the outer peripheral surface of the air pump, a connecting pipe is inserted through and snapped onto one end of the air pump, the other end of the connecting pipe is welded through and welded to one end of the spiral cooling pipe, an exhaust pipe is welded through and welded to the other end of the spiral cooling pipe, the connecting pipe and the exhaust pipe are respectively inserted through and inserted into both ends of the cold water tank, the exhaust pipe is inserted through and snapped onto the outer peripheral surface of the cooling conveying tank, and one end of the exhaust pipe is inserted through and inserted into the outer peripheral surface of the slow-flow feed pipe;

[0016] The hot air in the cooling conveying tank is drawn into the spiral cooling pipe by an air pump. Cold water is used to cool the air in the spiral cooling pipe. Then, the cold air is introduced into the cooling conveying tank through the exhaust pipe. The flow of cold air in the cooling conveying tank further cools the compound fertilizer. The airflow in the opposite direction to the compound fertilizer conveying slows down the speed at which the compound fertilizer passes through the cooling conveying tank, allowing the compound fertilizer to be fully cooled in the cooler. At the same time, the cold air is quickly drawn to the slow-flowing discharge pipe end of the cooling conveying tank, making the air pressure at the discharge end of the cooling conveying tank relatively high. This prevents the entry of outside cold air, avoids contamination of the compound fertilizer, and ensures product quality.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that when compound fertilizer passes through a cooling conveying tank and a cold water tank, the cooling water sprayed onto the cylinder is used to cool the cylinder body, which in turn cools the air inside the cylinder, ultimately cooling the compound fertilizer. However, the cooling process takes time, making it difficult to quickly cool the fertilizer inside the cylinder. The cold water tank cools the surface of the cooling conveying tank, further cooling the air and fertilizer inside. Simultaneously, an air pump draws the high-temperature air inside the cooling conveying tank into a spiral cooling pipe, where the air is cooled by the cold water. This cooled air then enters the other end of the cooling conveying tank, further cooling the compound fertilizer, thus greatly improving the cooling efficiency of the compound fertilizer.

[0019] 2. This utility model solves the problem of large-scale compound fertilizer cooling in sealed coolers, which typically require a large volume to accommodate the fertilizer, but this large volume occupies significant space in the production workshop, and the long cooling time required for large quantities of compound fertilizer reduces production efficiency. Conversely, non-sealed coolers, to ensure sufficient cooling time, are often too long, making layout in the production workshop inconvenient. Furthermore, non-sealed coolers can easily introduce outside air, potentially affecting product quality. The material conveying motor drives the screw conveyor... When the material assembly rotates to convey compound fertilizer, the air pump draws air cooled by the cold water tank into the cooling conveying tank. The flow of cold air in the cooling conveying tank cools the compound fertilizer, and the airflow in the opposite direction to the fertilizer's conveying direction slows down the fertilizer's speed through the cooling conveying tank, ensuring that the compound fertilizer is fully cooled in the cooler. This eliminates the need to extend the length of the cooling conveying tank to ensure cooling efficiency. At the same time, the cold air is quickly drawn to the slow-flowing discharge pipe end of the cooling conveying tank, resulting in a relatively high air pressure at the discharge end. This prevents the entry of external cold air, avoids contamination of the compound fertilizer, and ensures product quality. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-6 As shown, this utility model is a cooling machine for producing high-tower compound fertilizer, including a cooling conveying tank 1 and a cold water tank 2. A conveying motor 101 is snapped and fixed at one end of the cooling conveying tank 1. A spiral conveying assembly 105 is attached inside the cooling conveying tank 1. A cold water tank 2 is snapped and fixed to the outer circumference of the cooling conveying tank 1. An air pump 201 is snapped and fixed at one end of the cold water tank 2. A spiral cooling pipe 207 is provided inside the cold water tank 2 and is sleeved on the outer circumference of the cooling conveying tank 1.

[0030] After being dried by a drying device, the processed high-tower compound fertilizer enters the cooling conveying tank 1 through the slow-flow feed pipe 102. Simultaneously, some high-temperature air is introduced into the cooling conveying tank 1. The conveying motor 101 drives the screw conveying assembly 105 to rotate, causing the fertilizer to move along the cooling conveying tank 1. Cold water is pumped into the cold water tank 2 by a water pump, which cools the cooling conveying tank 1, further cooling the air and compound fertilizer inside. Simultaneously, the air pump 201 evacuates air from the slow-flow feed pipe 102, allowing the high-temperature air to cool down. The fertilizer enters the spiral cooling pipe 207 and is cooled by cold water. The cooled air then enters the other end of the cooling conveying tank 1. The cold air flows in the opposite direction to the movement of the compound fertilizer in the cooling conveying tank 1, cooling the compound fertilizer and slowing down the speed at which the compound fertilizer passes through the cooling conveying tank 1. At the same time, the cold air is quickly drawn to one end of the slow-flow discharge pipe 103 of the cooling conveying tank 1, so that the air pressure at the discharge end of the cooling conveying tank 1 is relatively high, preventing the entry of outside cold air. The cooled fertilizer is discharged through the slow-flow discharge pipe 103.

[0031] Among them, such as Figure 1-4As shown, a slow-flow feed pipe 102 is welded through the top of one side of the cooling feed tank 1, and a slow-flow discharge pipe 103 is welded through the bottom of the other side of the cooling feed tank 1. The slow-flow feed pipe 102 and the slow-flow discharge pipe 103 are located at both ends of the cold water tank 2, respectively. One end of the feeding motor 101 is rotatably connected to a drive rod 104, and the spiral feeding assembly 105 is snapped and fixed to the outer circumference of the drive rod 104. A vent hole 106 is opened through one side of the spiral feeding assembly 105, and the drive rod 104 is inserted through and inserted into one end of the cooling feed tank 1.

[0032] After being dried by the drying device, the high-tower compound fertilizer enters the cooling conveying tank 1 through the slow-flow feed pipe 102 under the action of gravity. The drive rod 104 and the screw conveying assembly 105 are driven by the conveying motor 101 to rotate, so that the compound fertilizer moves along the cooling conveying tank 1 and is cooled. The cold air entering the cooling conveying tank 1 moves through the vent 106 to cool the compound fertilizer. After being fully cooled, the compound fertilizer is discharged through the slow-flow discharge pipe 103.

[0033] Among them, such as Figure 1 , 2 As shown in Figures 5 and 6, a support frame 202 is fixedly attached to the bottom of the outer periphery of the cold water tank 2. A water inlet pipe 203 is welded through the bottom of one side of the cold water tank 2, and a drain pipe 204 is welded through the top of the other side of the cold water tank 2. An exhaust pipe 206 is attached through the bottom of the outer periphery of the air pump 201. A connecting pipe 205 is attached through one end of the air pump 201. The other end of the connecting pipe 205 is welded through one end of the spiral cooling pipe 207. An exhaust pipe 208 is welded through the other end of the spiral cooling pipe 207. The connecting pipe 205 and the exhaust pipe 208 are respectively inserted through and inserted into both ends of the cold water tank 2. The exhaust pipe 206 is attached through and attached to the outer periphery of the cooling conveying tank 1. One end of the exhaust pipe 208 is inserted through and inserted into the outer periphery of the slow-flow feed pipe 102.

[0034] Connect the water inlet pipe 203 to the water pump. The water pump allows a large amount of cold water to enter the cold water tank 2 through the water inlet pipe 203. The cold water cools the surface of the cooling conveying tank 1 and further cools the air and compound fertilizer inside the cooling conveying tank 1. The heated water is discharged through the drain pipe 204. At the same time, the air pump 201 draws air from the slow-flow feed pipe 102, allowing the high-temperature air to enter the spiral cooling pipe 207. The air is cooled by the cold water. The cold air flows back into the cooling conveying tank 1 through the exhaust pipe 206 and cools the compound fertilizer inside the cooling conveying tank 1 through the flow of cold air.

[0035] The specific working principle of this utility model is as follows: The inlet pipe 203 is connected to the water pump, and the slow-flow feed pipe 102 is connected to the outlet of the drying device. The dried high-tower compound fertilizer, under gravity, enters the cooling conveying tank 1 through the slow-flow feed pipe 102. The conveying motor 101 drives the drive rod 104 and the screw conveying assembly 105 to rotate, causing the compound fertilizer to move along the cooling conveying tank 1. The water pump, through the inlet pipe 203, introduces a large amount of cold water into the cold water tank 2. The cold water cools the surface of the cooling conveying tank 1, further... The air and compound fertilizer in the cooling conveying tank 1 are cooled down, and the heated water is discharged through the drain pipe 204. At the same time, the air pump 201 draws air into the slow-flow feed pipe 102, so that the high-temperature air enters the spiral cooling pipe 207. The air is cooled by cold water, and the cold air flows back into the cooling conveying tank 1 through the exhaust pipe 206. The cold air entering the cooling conveying tank 1 moves through the vent 106, slowing down the movement of the compound fertilizer while cooling it. After the compound fertilizer is fully cooled, it is discharged through the slow-flow discharge pipe 103.

[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
