Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, and particularly relates to a surface coating device for organic fertilizer particles. Background Art

[0002] The surface coating technology for organic fertilizers is a process of coating a protective film on the surface of fertilizer particles. This film can slowly release the nutrients in the fertilizer, improve the fertilizer utilization rate, reduce environmental pollution, and improve the soil structure. The coating process is generally completed by a coating machine, which can evenly coat the coating material on the surface of the fertilizer particles. The coated organic fertilizer not only has good physical properties, such as anti-caking and moisture-proof, but also its chemical properties are improved, such as reducing nitrogen volatilization and increasing the utilization rate of phosphorus and potassium.

[0003] In the prior art, the coating machine used for organic fertilizers is usually a rotary drum coating machine. When it comes to the situation where organic fertilizers adhere together after granulation and before coating, this will cause the volume of the particles to increase, and there will be powder during the transfer process. If directly coated, it will inevitably affect the product quality. For example, see the patent number: CN202321339687.2, and the patent name: A coating machine for organic fertilizers. Although this device can achieve the crushing of large particles and the filtration of impurities, its structure is too complex, not easy to maintain, and it cannot screen out the powder, affecting the product quality and having poor practicability.

[0046] Please refer to Figure 1 and Figure 2 simultaneously. Now, the surface coating device for organic fertilizer particles provided by the present utility model will be described. The surface coating device for organic fertilizer particles includes a base 10, a coating component 20, a driving component 30 and a screening component 40. The top of the base 10 has a flipping part. The coating component 20 is rotatably arranged on the flipping part, has a feeding end and a discharging end, and the coating component 20 can coat the organic fertilizer particles.

The top end of the screening component 40 is provided with a feeding port, and the bottom end is provided with a discharging port that can extend into the feeding end. The screening component 40 can screen out large particles and powders in the transferred organic fertilizer particles.

[0047] The surface coating device for organic fertilizer particles provided in this embodiment, compared with the prior art, has a flipping part provided on the base 10 for installing the coating assembly 20, and can also adjust the inclination of the coating assembly 20. Driven by the driving assembly 30, it can ensure the adjustment of the film residence time of the organic fertilizer particles. The screening assembly 40 is provided on the base 10, which can screen out large particles and powders in the organic fertilizer particles, thereby ensuring that the particle sizes of the materials entering the coating assembly 20 are basically the same, ensuring the film effect and the product quality, and having strong practicability.

[0048] In some embodiments, the above-mentioned screening assembly 40 can adopt the structure as Figure 2 shown. Refer to Figure 2 , the screening assembly 40 includes a hopper 41, a guide plate 42, a screening structure 43 and a first screen 44. The hopper 41 is fixedly arranged on the base 10 and has a cavity. The feeding port is located at the top of the hopper 41, and the discharging port is located at the bottom of the hopper 41. The guide plate 42 is inclined and arranged in the cavity. The guide plate 42 divides the cavity into a first screening space and a material transfer cavity below the first screening space, and a communication port connecting the first screening space and the material transfer cavity is provided at the top of the guide plate 42. The screening structure 43 is arranged in the hopper 41 and has a screening part located in the first screening space, which can receive the materials added from the feeding port and cooperate with the guide plate 42 to screen out the powders in the materials. The first screen 44 is inclined and arranged in the material transfer cavity. The first screen 44 divides the material transfer cavity into a second screening space and a discharging space below the second screening space. The first screen 44 can screen out large particle organic fertilizers. The discharging space is communicated with the discharging port.

[0049] Specifically, the hopper 41 is provided with a first opening communicated with the first screening space and a second opening communicated with the second screening space.

[0050] The organic fertilizer materials entering from the feeding port are first sent onto the screening structure 43, and the screening structure 43 will screen out the powders in the materials so that the powders are exported through the guide plate 42 at the first opening. The remaining materials enter onto the first screen 44 through the communication port. As they slide down under their own gravity, the large particle organic fertilizers are intercepted and then exported at the second opening, while the particles with appropriate particle sizes pass through the first screen 44 and enter the discharging space, and then enter the film assembly through the discharging port for coating.

[0051] The independent setting of the screening assembly 40 on the base 10 and its simple internal structure are convenient for maintenance, can ensure the screening effect of large particles and powders, and is convenient for improving the product quality.

[0052] It should be noted that a telescopic pipe can be provided at the discharging port to ensure that it extends into the feeding end.
