Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer particle coating, in particular to fertilizer particle coating equipment. Background Art

[0002] Fertilizer granule coating is a surface coating process designed to improve the physical and chemical properties of fertilizers. By coating the surface of fertilizer granules with one or more layers of film, the compressive strength, moisture resistance, sustained release, and bioavailability of the fertilizer can be enhanced, while also reducing nutrient loss and environmental pollution. Furthermore, coating can be customized to add color and flavor, enhancing the product's market competitiveness. This technology is of great significance in modern agriculture.

[0003] In existing fertilizer granule coating equipment, fluidized bed technology is widely used to enhance the coating effect. However, these devices usually adopt the bottom spraying method, that is, spraying gas from the bottom of the equipment. Although this method improves the coating efficiency to a certain extent, it also leads to the problem of uneven coating. Due to the interaction between the airflow and the material particles, some particles inside and on the top may not be fully exposed to the coating liquid, while other particles may clog the equipment due to excessive coating. In addition, the bottom spraying method is also prone to powder leakage, that is, fine powder particles escape from the bottom of the fluidized bed, which not only affects the product quality, but may also cause pollution to the production environment. For this reason, we propose fertilizer granule coating equipment. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0034] like Figure 1-5 As shown, in this embodiment, the fertilizer particle coating equipment includes: a base 100, a coating assembly 300, and a bracket 200 fixedly connected to the base 100; the coating assembly 300 is arranged in the bracket 200 and can coat the fertilizer particles;

[0035] The coating assembly 300 includes: a cylinder 301, a hydraulic rod 304, a first adapter plate 305, a first rotating tube 306, a second rotating tube 307, a second adapter plate 308, a motor 309 and a one-way valve head 310. The cylinder 301 is fixedly connected to the bracket 200, and a limiting groove 302 is provided on the inner wall of the cylinder 301. The top of the cylinder 301 is rotatably connected to the cover 303; the hydraulic rod 304 is fixedly connected to the top of the cover 303, and the driving end of the hydraulic rod 304 extends into the cylinder 301; the first adapter plate 305 is arranged in the cylinder 301, and the driving end of the hydraulic rod 304 is fixedly connected to the first adapter plate 305; a plurality of first rotating tubes 306 and a second rotating tube 307 are fixedly connected to the first adapter plate 305. 306 are all rotatably connected to the outside of the first adapter plate 305; multiple second rotating tubes 307 are rotatably connected to the bottom ends of the multiple first rotating tubes 306; the second adapter plate 308 is rotatably set at the inner bottom of the cylinder 301, and the bottom ends of the multiple second rotating tubes 307 are all rotatably connected to the outside of the second adapter plate 308; the multiple first rotating tubes 306 and the second rotating tubes 307 are unidirectionally rotatably connected, so that the multiple first rotating tubes 306 and the second rotating tubes 307 can only rotate up and down in the Z-axis direction, but not left and right in the X-axis direction, so that the multiple first rotating tubes 306 and the second rotating tubes 307 can rotate around the central axis of the cylinder 301 as a whole;

[0036] The motor 309 is fixedly connected to the bottom of the cylinder 301, and the driving end of the motor 309 extends into the cylinder 301 and is fixedly connected to the second adapter plate 308; a plurality of one-way valve heads 310 are respectively fixedly connected to the outside of the plurality of first rotating tubes 306 and second rotating tubes 307; it should be noted that the motor 309 is a three-phase motor 309, and the direction of the current is changed by changing the phase sequence of the input power supply, thereby achieving forward and reverse rotation of the motor 309. In a three-phase motor 309, this is usually achieved by swapping the power supply connections of any two phases, so that the hydraulic rod 304, the cover 303, the first adapter plate 305, the first rotating tube 306, the second rotating tube 307, and the second adapter plate 308 in the coating assembly 300 can be driven to rotate forward and reverse as a whole, and the material is stirred by rotating 180 degrees in both forward and reverse directions. At the same time, the external wiring of the hydraulic rod 304 and the connecting tube 315 can be prevented from being entangled and broken.

[0037] In this embodiment, multiple first rotating tubes 306 and second rotating tubes 307 are respectively fixedly connected to the outside with air pipes 314, and a connecting tube 315 is fixedly connected to the first adapter plate 305. Multiple air pipes 314 are connected to the connecting tube 315, and the output ends of multiple air pipes 314 are respectively extended into the first rotating tube 306 and the second rotating tube 307 for gas supply. It should be noted that multiple air pipes 314 are connected to the connecting tube 315 in the group of coating components 300, and the multiple air pipes 314 and the group of connecting tubes 315 rotate synchronously without causing interference. Similarly, since the multiple air pipes 314 and the connecting tube 315 are made of rubber material, they are easy to stretch and bend and not easy to break. In addition, the multiple air pipes 314 and other mechanisms in the coating component 300 do not react with the material.

[0038] Specifically, fertilizer is input into the coating assembly 300 at the bottom, and then the coating material is input through the input pipe 317 of the coating assembly 300. The motor 309 of the coating assembly 300 is started to drive the second adapter plate 308 to rotate, thereby driving the multiple first rotating tubes 306 and the second rotating tubes 307 to rotate, stirring and mixing the base material and the coating material to achieve coating. During this process, external gas is connected through the connecting pipe 315 of the group, and then input into the multiple first rotating tubes 306 and the second rotating tubes 307 through the multiple air pipes 314. The gas is then ejected through the multiple one-way valve heads 310 to form an upward airflow, which suspends the material particles and maintains a fluidized state. The hydraulic rod 304 is started, and the hydraulic rod 304 drives the first adapter plate 305 to rise and fall, that is, drives the multiple first rotating tubes 306 and the second rotating tubes 307 to fold and rise, which can drive the multiple one-way valve heads 310 to perform a combined movement of telescoping and expanding in the X-axis direction and lifting and lowering in the Z-axis direction within the material, thereby making the material particles more evenly suspended and fluidized.

[0039] like Figure 5As shown, further, the rotational connections of the multiple first rotating tubes 306 and the second rotating tubes 307 are fixed with rubber sleeves 316. By providing the rubber sleeves 316, materials can be prevented from being blocked at the rotational connections of the first rotating tubes 306 and the second rotating tubes 307. Similarly, the first adapter plate 305, the second adapter plate 308, and the connections between the telescopic rod 311 and the rotating circle 313 can all be provided with rubber sleeves 316 to prevent materials from entering and interfering with the operation.

[0040] like Figure 1 As shown, further, the coating components 300 are arranged in multiple groups, and the multiple groups of coating components 300 are arranged equidistantly in the upper and lower parts in the bracket 200. The tops of the multiple cylinders 301 are fixedly connected with input tubes 317, and the bottoms of the multiple cylinders 301 are fixedly connected with output tubes 318. The multiple output tubes 318 are respectively connected to the cylinders 301 set at the bottom. By setting the output tubes 318, multiple groups of coating components 300 can be connected to achieve upper and lower communication. Through the cooperation of multiple groups of coating components 300, coating of various materials can be achieved. Example 2

[0041] On the basis of the first embodiment, in order to prevent the material from adhering to the inner wall of the cylinder 301 , a telescopic rod 311 , a scraping bar 312 and a rotating ring 313 are provided.

[0042] like Figure 2-3 As shown, in this embodiment, the rotating connection of multiple first rotating tubes 306 and second rotating tubes 307 is rotatably connected with a telescopic rod 311, and the multiple telescopic rods 311 are all arranged around the central axis of the first adapter plate 305, and one end of the multiple telescopic rods 311 is fixedly connected to two scraping strips 312; a rotating ring 313 is rotatably clamped in the limiting groove 302, and one end of the multiple telescopic rods 311 is rotatably connected to the rotating ring 313, and a groove is provided on the outside of the rotating ring 313 for clamping in the limiting groove 302 to facilitate rotational clamping.

[0043] During specific implementation, when the multiple first rotating tubes 306 and the second rotating tubes 307 rotate, they will drive the multiple telescopic rods 311 to rotate synchronously. The multiple telescopic rods 311 drive the rotating circle 313 to rotate within the limiting groove 302 to provide limiting support. The multiple telescopic rods 311 synchronously drive the multiple scraping strips 312 to rotate. The multiple scraping strips 312 scrape the inner wall of the cylinder 301 to scrape and clean the material attached to the inner wall of the cylinder 301. It should be noted that since the multiple scraping strips 312 are made of tough and elastic materials, they can adapt to the curvature changes of the inner wall of the cylinder 301 and will not interfere with the rotation of the rotating circle 313.

[0044] like Figure 2-3As shown, further, the hydraulic rod 304 drives the multiple first rotating tubes 306 and the second rotating tubes 307 to fold and lift, and at the same time, it drives the multiple telescopic rods 311 to rotate and extend synchronously to adapt to the folding and lifting of the first rotating tubes 306 and the second rotating tubes 307. It should be noted that there is no need to set a damping mechanism in the telescopic rod 311. This is an existing technology and will not be elaborated on.

[0045] Working principle: The coating components 300 are arranged equidistantly in the upper and lower parts of the bracket 200. First, the fertilizer is input through the input pipe 317 set at the top, and then the motor 309 is started. The motor 309 drives the corresponding second adapter plate 308 to rotate, and then drives multiple first rotating tubes 306 and second rotating tubes 307 to rotate, stirring the fertilizer. The fertilizer particles used as the base material are evenly distributed by stirring, and then the valve on the output pipe 318 is opened to input the fertilizer into the coating component 300 at the bottom. Then, the coating material is input through the input pipe 317 of the coating component 300, and the motor 309 of the coating component 300 is started to drive the second adapter plate 308 to rotate, which in turn drives multiple first rotating tubes 306 and second rotating tubes 307 to rotate. , the base material and the coating material are stirred and mixed to achieve coating. During this process, external gas is connected through the connecting pipe 315 of the group, and then input into the multiple first rotating tubes 306 and the second rotating tubes 307 through multiple air pipes 314, and then ejected through multiple one-way valve heads 310 to form an upward airflow, so that the material particles are suspended and maintained in a fluidized state, and the hydraulic rod 304 is started. The hydraulic rod 304 drives the first adapter plate 305 to rise and fall, that is, drives the multiple first rotating tubes 306 and the second rotating tubes 307 to fold and rise and fall, which can drive the multiple one-way valve heads 310 to perform a comprehensive movement of telescopic expansion in the X-axis direction and lifting and lowering in the Z-axis direction in the material, so that the material particles can be suspended and fluidized more evenly. Through the cooperation of multiple groups of coating components 300, coating of various materials can be achieved.
