Description

Technical Field

[0001] This utility model relates to the field of disc granulation technology, specifically to an experimental device for disc granulation of nitro compound fertilizer. Background Technology

[0002] Compound fertilizers have advantages such as high nutrient content, few by-products, and good physical properties. They play a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. However, they also have some drawbacks. For example, their nutrient ratios are always fixed, while different soils and crops require different types, quantities, and ratios of nutrients. Therefore, it is best to conduct soil testing before use to understand the soil texture and nutrient status. Additionally, it is important to use them in combination with single-element fertilizers to achieve better results. In production, compound fertilizers need to be granulated using a granulator to form compound fertilizer granules. Common granulation processes for compound fertilizers include... Rotary drum granulation, disc granulation, spray granulation, and granulation tower granulation are some of the methods used in granulation. Among them, the disc granulator works by adding water to the powder, which forms a thin water film on the surface of the powder particles. Due to the surface tension of water, the water and powder combine to form very small spherical nuclei. As the disc rotates, the spherical nuclei adsorb material and gradually become granules. Under the action of centrifugal force, the granules roll towards the edge of the disc. During this process, the granules continuously adhere to powder and become spherical. The spherical material is discharged from the disc under the action of centrifugal force. The spherical material is continuously discharged from the disc, and new material is continuously added to the feed disc, thus achieving granulation in a continuous cycle.

[0003] Since the angle of the disc is very important in the granulation process, multiple angle experiments are required to determine the appropriate angle. Therefore, we propose a disc granulation experimental device for nitro compound fertilizer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a disc granulation experimental device for nitro compound fertilizer.

[0006] The design incorporates an adjustable disc, allowing for experimental study of the disc's angle's impact on granulation. This enables the identification of the optimal angle range, facilitating subsequent mass production. When the disc's angle needs adjustment, the handle is manually rotated, causing gear two to rotate, which in turn rotates gear one and the rotating rod, thus adjusting the disc's angle.

The middle part of the rear surface of the second bracket is fixedly connected to the second motor. The output shaft of the second motor passes through the round hole on the second bracket and is fixedly connected to the rear end of the screw.

[0010] The design includes a movable support frame 1, which allows the position of the disc to be adjusted according to its tilt, ensuring that the compound fertilizer falls within the conveyor belt. When adjusting the position, an external control switch group controls a motor 2 to rotate the screw, which in turn moves the support frame 1, allowing the disc to reach the appropriate position.

[0011] Furthermore, the device also includes a limiting rod, a limiting hole is opened on the upper part of the right side surface of the bracket one, the limiting rod is slidably connected in the limiting hole, and the left end of the limiting rod passes through the limiting groove and contacts the gear two.

[0012] A limit rod is designed to lock the second gear, thereby maintaining the adjusted angle.

[0013] Furthermore, the device also includes an angled disc, with a conveyor belt positioned below the disc. The input end of the conveyor belt is electrically connected to the output end of an external power supply via an external control switch group.

[0014] The compound fertilizer is transported by a conveyor belt as it falls.
