Description

Technical Field

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

[0002] Compound fertilizer is a chemical fertilizer containing multiple nutrients such as nitrogen, phosphorus, and potassium. Through scientific formulation, it meets the growth needs of crops. Its advantages lie in its balanced nutrient content, high utilization rate, and ability to supplement multiple elements at once, reducing the frequency of fertilization and improving agricultural production efficiency. Compound fertilizers can be divided into binary and ternary types according to their composition, suitable for various soils and crops, especially effective in grain, vegetable, and fruit tree cultivation. After the compound fertilizer completes the drying process, due to its high temperature, it is prone to clumping during transportation. Therefore, the finished compound fertilizer needs to be cooled. The traditional cooling method is to allow the finished fertilizer to cool naturally on a conveyor belt, which is a slow cooling rate. To meet the bagging temperature requirements, fans need to be installed on both sides of the conveyor belt for auxiliary cooling, which leads to significant dust pollution inside the production workshop, affecting the working environment of the workers. Utility Model Content

[0003] The purpose of this utility model is to provide a cooling device for conveying compound fertilizer products, in order to solve the problems mentioned in the background art. The traditional cooling method is that the finished fertilizer product is naturally cooled on the conveyor belt, which has a slow cooling rate. In order to meet the bagging temperature requirements, fans need to be installed on both sides of the conveyor belt to assist in cooling, which leads to a lot of dust in the production workshop and affects the working environment of the staff.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compound fertilizer product conveying and cooling device, comprising a conveying pipe, a conveying screw rotatably connected inside the conveying pipe via bearings, a cooling water tank on the outer surface of the conveying pipe, a cover plate sealed at the upper end of the cooling water tank by bolts, partitions staggered between the cooling water tank and the cover plate, an output port and an input port respectively penetratingly connected at both ends of the cover plate, a heat dissipation water tank located at the middle of the rear side of the cooling water tank, a cooling fan located at the rear side of the heat dissipation water tank, and a circulation pump connected to the output end of the heat dissipation water tank via a pipe.

[0005] Preferably, a speed reducer is provided on one side of the conveying pipe, the output end of the speed reducer is connected to the main shaft of the conveying screw, the input end of the speed reducer is provided with a power motor, the upper end of the conveying pipe is provided with an inlet on one side of the cooling water tank, and the lower end of the conveying pipe is provided with an outlet on the other side of the cooling water tank.

[0006] Preferably, the lower end of the cooling water tank is provided with process bevels on both the front and rear sides, and the lower ends of the output pipe and the input pipe extend into the interior of the cooling water tank and are above the conveying pipe.

[0007] Preferably, a circulation pipe is connected between the output port and the input end of the heat dissipation tank, and a return pipe is connected between the input port and the output end of the circulation pump.

[0008] Preferably, both ends of the conveying pipe are provided with reinforcing end plates, and both ends of the main shaft of the conveying screw are rotatably connected to the reinforcing end plates on both sides through bearings.

[0009] Compared with the prior art, the beneficial effects of this utility model are: replacing the traditional conveyor belt conveying method with pipe auger conveying, replacing the traditional method of natural cooling of finished fertilizer on the conveyor belt, setting a cooling water tank on the outside of the conveying pipe, improving the cooling efficiency of waste material, shortening the cooling time, ensuring that the fertilizer can reach the temperature required for bagging, reducing fertilizer dust, and ensuring the working environment of the staff.

[0018] In use, the dried compound fertilizer is conveyed inside the conveying pipe 1 by the rotating conveying screw 2. A cooling water tank 3 is installed on the outside of the conveying pipe 1, and a cover plate 4 is installed on the upper end of the cooling water tank 3 to form a closed space. A partition 5 is installed inside the cooling water tank 3. Under the action of the circulating pump 10, the cooling water is conveyed from the inside of the cooling water tank 3 to the inside of the heat dissipation tank 8 through the output pipe 6. A cooling fan 9 is installed on the rear side of the heat dissipation tank 8. The cooling water is cooled by the cooling fan 9 and the heat dissipation tank 8. After cooling, the cooling water is input into the inside of the cooling water tank 3 through the input pipe 7 under the action of the circulating pump 10. The internal temperature of the conveying pipe 1 is reduced by heat exchange, thereby cooling the fertilizer.

[0019] A reducer 11 is provided on one side of the conveying pipe 1. The output end of the reducer 11 is connected to the main shaft of the conveying screw 2. A power motor 12 is provided at the input end of the reducer 11. An inlet 13 is provided at the upper end of the conveying pipe 1 on one side of the cooling water tank 3. An outlet 14 is provided at the lower end of the conveying pipe 1 on the other side of the cooling water tank 3. The power of the power motor 12 is reduced by the reducer 11 and converted into the rotation of the conveying screw 2 inside the conveying pipe 1. Fertilizer is input into the inside of the conveying pipe 1 from the inlet 13, conveyed along the conveying pipe 1 under the action of the conveying screw 2, and output to the outside through the outlet 14.

[0020] The lower end of the cooling water tank 3 is provided with process bevels 15 on both the front and rear sides. The lower ends of the output port 6 and the input port 7 extend into the interior of the cooling water tank 3 and are above the conveying pipe 1. The process bevels 15 on the lower end of the cooling water tank 3 reduce the overall structural weight and the amount of cooling water stored inside the cooling water tank 3, thus reducing the overall structural weight while ensuring the cooling effect.

[0021] A circulation pipe 16 is connected between the output port 6 and the input end of the heat dissipation tank 8, and a return pipe 17 is connected between the input port 7 and the output end of the circulation pump 10. Cooling water is input into the heat dissipation tank 8 through the circulation pipe 16 and then transported back to the cooling water tank 3 through the return pipe 17.

[0022] Both ends of the conveying pipe 1 are provided with reinforcing end plates 18. The two ends of the main shaft of the conveying screw 2 are rotatably connected to the reinforcing end plates 18 on both sides through bearings. The reinforcing end plates 18 at both ends of the conveying pipe 1 enhance the connection strength between the conveying screw 2 and the reducer 11 and the conveying pipe 1.
