Description

Technical Field

[0001] The invention relates to the technical field of fertilizer processing, in particular to a highly uniform drying and granulation integrated device for fertilizer processing. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility levels. It is one of the material bases of agricultural production, and mainly includes ammonium phosphate fertilizers, water-soluble fertilizers of large amounts of elements, fertilizers of medium amounts of elements, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. In current agricultural production, granular fertilizers are mostly used, and fertilizers basically need to go through a granulation process. The benefits of fertilizer granulation include: improving the physical properties of the product, thereby reducing hazards such as moisture absorption, caking and dusting during the sales and distribution process; granular fertilizers are suitable for fertilization using machinery and improving fertilization efficiency; fertilizer granulation can integrate multiple nutrients in the same granule, simplifying fertilization operations; compared with the application of powdered fertilizers, the application of granular fertilizers can slow down the dissolution rate of nutrients, thereby reducing the damage to seeds or seedlings caused by electrolytes and reducing nutrient losses, etc.

[0003] In the process of fertilizer granulation, the raw materials are first stirred, and then granulated. During the granulation process, a certain amount of water needs to be added for mixing to ensure that the fertilizer raw materials can be formed and the granulation process is completed smoothly. After the granulation is completed, the fertilizer granules need to be dried to prevent the granules from agglomerating due to residual moisture, which will affect the quality of the fertilizer. In the current production of fertilizer granules, the granulation technology is very mature, but the drying process is very backward. The granules after granulation are only dried using traditional dryers, and the drying effect is very limited. Since the fertilizer granules after granulation are piled together, traditional drying cannot evenly and efficiently dry these wet fertilizer granules, which often causes the fertilizer granules to clump and even affects the quality of the fertilizer.

[0018] In order to facilitate the problem to be solved, the embodiment of the present invention provides a high-uniform drying and granulation integrated device for fertilizer processing. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

When the device is working, the raw materials used for fertilizer granulation are put into the tank body 5 from the feed port 6, and enter the granulation disk 10 through the discharge pipe 7. At this time, the granulation disk 10 starts to rotate at a certain speed driven by the first motor 9, and the water pump 14 is started at this time to pump water from the inside of the water tank 13, and the water is discharged through the outlet pipe 7. The tube 15 and the nozzle 16 spray evenly above the granulation disk 10 to provide an appropriate amount of moisture for granulation and facilitate fertilizer granulation. After the granulation disk 10 successfully granulates, the fertilizer particles will overflow into the mounting disk 17. In order to prevent the fertilizer particles overflowing from the granulation disk 17 from being accumulated on the first conveyor 3 at the bottom, the second motor 21 rotates to drive the sorting disk 19 to rotate, and the fertilizer particles will also rotate with the sorting disk 19. When the gaps between the four triangular blocks 35 on the mounting column 34 coincide with the through groove 18, the fertilizer particles will flow out of the through groove 18, thereby achieving the effect of controlling the amount of fertilizer particles accumulated on the first conveyor 3 and the second conveyor 4.

At this time, the second motor 21 rotates to drive the sorting disk 19 to rotate, and the fertilizer particles will also rotate with the sorting disk 19. When the gaps between the four triangular blocks 35 on the mounting column 34 coincide with the through groove 18, the fertilizer particles will flow out of the through groove 18, thereby achieving the effect of controlling the amount of fertilizer particles accumulated on the first conveyor 3 and the second conveyor 4. In order to achieve the effect of sorting the fertilizer particles, at this time, the sorting fan 32 is started, and the heater 33 is started at the same time to blow hot air to the falling fertilizer particles, blowing smaller particles onto the second conveyor 4, and larger fertilizer particles will fall onto the first conveyor 3.

Four triangular blocks 35 are symmetrically fixedly mounted on the side wall of the mounting column 34. When the gaps between the four triangular blocks 35 on the mounting column 34 coincide with the through groove 18, the fertilizer particles will flow out of the through groove 18.

[0026] The controller 31 is electrically connected to the first motor 9, the second motor 21, the water pump 14, the heater 33 and the dryer 30. The speed of the first motor 9 and the second motor 21, the water output of the water pump 14 and the temperature of the heater 33 and the dryer 30 are set by the controller 31.

[0027] A panel 36 is fixedly mounted on the upper surface of the first conveyor 3 and the second conveyor 4 to prevent the fertilizer from being blown out of the platform.
