Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to a urea-based compound fertilizer coating device. Background Technology

[0002] Compound fertilizers refer to chemical fertilizers containing two or more nutrients. They have advantages such as high nutrient content, few by-products, and good physical properties. Compound fertilizers with urea as the nitrogen source are called urea-based compound fertilizers. Urea-based compound fertilizers are high-concentration nitrogen, phosphorus, and potassium multi-element compound fertilizers produced by secondary processing of urea as the nitrogen source and basic fertilizers such as ammonium chloride, potassium chloride, potassium sulfate, superphosphate, and ammonium phosphate. Urea-based compound fertilizers produced through crushing, granulation, and cooling often have the problem of clumping during the cooling process, requiring coating.

[0003] However, current coating devices typically use a single nozzle to spray and coat the stirred urea-based compound fertilizer. This setup may not result in even and effective spraying onto the urea-based compound fertilizer, thus reducing the coating effect. Therefore, we propose a urea-based compound fertilizer coating device. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a urea-based compound fertilizer coating device. The device feeds urea-based compound fertilizer granules into a spiral guide plate inside a coating tank via a feeding channel. Simultaneously, a chemical assembly delivers coating agent through through-holes into a first cavity under the action of a guide cone. Multiple first nozzles then spray the coating agent onto the urea-based compound fertilizer granules on the spiral guide plate to perform the coating process. Furthermore, unused coating agent can continue to flow down through the dispensing holes to perform a secondary coating on the urea-based compound fertilizer granules below the spiral guide plate, thereby improving the coating efficiency of the urea-based compound fertilizer granules. Simultaneously, the drive component operates, causing the first rotating shaft to operate. The first rotating shaft then drives the second gear to rotate, which in turn drives the first gear to rotate. The first gear then drives the first nozzle to rotate around the second rotating shaft. Thus, the multiple rotating first nozzles ensure that the coating agent is evenly sprayed onto the urea-based compound fertilizer granules. In addition, some of the coating agent is fed into the auxiliary coating component through the second cavity, further enhancing the coating effect of the coating agent on the urea-based compound fertilizer granules. The coated urea-based compound fertilizer granules are discharged and collected from the discharge port, and the remaining coating agent is discharged and collected from the discharge pipe. This effectively solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a urea-based compound fertilizer coating device, comprising a coating tank, a spiral guide plate, a pharmaceutical component, and an auxiliary coating component; A pharmaceutical assembly is mounted on the upper surface of the coating barrel.

The end of the feeding channel near the second rotating shaft is located directly above the top of the spiral guide plate. A discharge port is provided on the lower outer side of the coating barrel corresponding to the bottom of the spiral guide plate. A pharmaceutical assembly is evenly placed in the middle of the first cavity. The device is equipped with multiple straight supports, which together mount a guide cone. The guide cone is higher in the middle and lower at the edges. A through hole is opened in the middle of the upper surface of the first gear, which is located directly above the guide cone.

A control valve is provided on the drug discharge pipe. Supports are symmetrically installed on both sides of the lower surface of the coating barrel.

[0006] Furthermore, the pharmaceutical assembly includes a pharmaceutical tank mounted on the upper surface of the coating container.

The lower end of the inlet pipe is located inside a through hole. The first water pump is controlled by an external controller to operate, and the first water pump delivers the coating pharmaceutical from the pharmaceutical tank into the first cavity through the inlet pipe and the through hole.

[0007] Furthermore, the auxiliary coating assembly includes a connecting pipe installed on the lower surface of the fixed support. The lower end of the connecting pipe is connected to the upper end of a four-way pipe, and the other three ends of the four-way pipe are each connected to a return pipe. A second water pump is installed on the return pipe, and multiple second nozzles are evenly installed on the return pipe. Part of the coating agent is introduced into the return pipe through the second cavity, the connecting pipe, the four-way pipe, and the second water pump. Under the action of the multiple second nozzles, the coating agent is sprayed laterally onto the urea-based compound fertilizer granules on the spiral guide plate, thereby further enhancing the coating effect on the urea-based compound fertilizer granules.

[0008] Furthermore, the drive assembly includes a motor bracket mounted on the upper surface of the coating barrel, on which a motor is mounted.

Additionally, some of the coating agent is fed into the auxiliary coating component through the second cavity, further enhancing the coating effect on the urea-based compound fertilizer granules. The coated urea-based compound fertilizer granules are discharged and collected from the outlet, while the remaining coating agent is discharged and collected from the discharge pipe.

[0013] Please see Figs. 1-2 This embodiment provides a technical solution: a urea-based compound fertilizer coating device, including a coating tank 1, a spiral guide plate 20, a reagent component and an auxiliary coating component; A pharmaceutical assembly is mounted on the upper surface of the coating tank 1.

A discharge pipe 9 is connected and installed on the lower surface of the coating tank 1. A control valve 8 is provided on the discharge pipe 9. Supports 10 are symmetrically installed on both sides of the lower surface of the coating tank 1.

[0014] In use, urea-based compound fertilizer granules are fed into the spiral guide plate 20 inside the coating tank 1 through the feeding channel 7. Simultaneously, the agent assembly operates, feeding the coating agent through the through-hole into the first cavity 12 under the action of the guide cone 14. Then, multiple first nozzles 13 spray the coating agent onto the urea-based compound fertilizer granules on the spiral guide plate 20 to perform the coating process. Furthermore, under the action of the dispensing hole 21, unused coating agent can continue to flow down to perform a secondary coating on the urea-based compound fertilizer granules below the spiral guide plate 20, thereby improving the coating effect. At the same time, the drive assembly operates... The first rotating shaft 19 operates, which drives the second gear 18 to rotate.

The external controller controls the operation of the motor 3, which drives the first rotating shaft 19 to rotate, thereby completing the rotation of the first rotating shaft 19 electrically.

[0018] The working principle of the urea-based compound fertilizer coating device provided by this utility model is as follows: During use, urea-based compound fertilizer granules are fed into the spiral guide plate 20 inside the coating tank 1 through the feeding channel 7. Simultaneously, the agent assembly delivers the coating agent through the through-hole into the first cavity 12 under the action of the guide cone 14. Then, multiple first nozzles 13 spray the coating agent onto the urea-based compound fertilizer granules on the spiral guide plate 20 to perform the coating process. Furthermore, under the action of the dispensing hole 21, unused coating agent can continue to flow downwards to perform a secondary coating on the urea-based compound fertilizer granules below the spiral guide plate 20, thereby improving the coating effect on the urea-based compound fertilizer granules. The coating effect is achieved by simultaneously driving the drive component to operate the first rotating shaft 19, which in turn drives the second gear 18 to rotate.

This multi-nozzle rotation ensures the coating agent is evenly sprayed onto the urea-based compound fertilizer granules. Additionally, some of the coating agent is fed into the auxiliary coating component through the second cavity 23, further enhancing the coating effect on the urea-based compound fertilizer granules. The coated urea-based compound fertilizer granules are discharged and collected from the discharge port 25, while the remaining coating agent is discharged and collected from the discharge pipe 9. An external controller controls the first water pump 2, which pumps the coating agent from the agent tank 5 into the first cavity 12 through the inlet pipe 4 and the through-hole. Part of the coating agent is introduced into the return pipe 16 through the second cavity 23, connecting pipe, four-way pipe, and second water pump 17. Under the action of multiple second nozzles 15, the coating agent is sprayed laterally onto the urea-based compound fertilizer granules on the spiral guide plate 20 to further enhance the coating effect on the urea-based compound fertilizer granules. The motor 3 is controlled by an external controller, and the operation of the motor 3 drives the first rotating shaft 19 to rotate, thereby completing the rotation of the first rotating shaft 19 electrically.
