Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer processing technology, specifically to a compound fertilizer uniform granulator. Background Technology
[0002] Compound fertilizer refers to chemical fertilizer containing two or more of the following nutrients: nitrogen, phosphorus, and potassium. Compound fertilizer has the advantages of high nutrient content, few by-products, and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. A fertilizer granulator is a device that processes fertilizer raw materials into granules.
[0003] In existing technologies for granulating compound fertilizers, the prepared fertilizer powder needs to be poured into a granulator first, and then the granulator uses rollers to granulate it. However, during the granulation process of compound fertilizers, the compound fertilizer tends to accumulate on the rollers, resulting in uneven feeding of the compound fertilizer. This leads to insufficient extrusion of the compound fertilizer powder by the existing granulator, resulting in fertilizer particles that are not full and have uneven particle size, thus reducing the granulation quality of the compound fertilizer. In view of this, a uniform granulator for compound fertilizers is proposed. Utility Model Content

[0040] The storage box 15 is movably installed in the inner wall of the screening box 10;
[0041] When using this compound fertilizer uniform granulator, the fertilizer to be crushed is added to the feed hopper 2. The first motor 3 is then started, driving the crushing blades 16 to rotate, thus initially crushing the large pieces of fertilizer raw material in the feed hopper 2 into smaller chunks or granules. These smaller pieces of fertilizer fall into the cylinder 5. The second motor 4 is then started, driving the conveying screw 6 to rotate. The rotation of the conveying screw 6 transports the pre-processed material in the cylinder 5 from the feed inlet 7 to the discharge outlet 8. The efficiency of material conveying can be controlled. To prevent excessive material from being fed into the crushing hopper 9, the fertilizer falls into the crushing hopper 9.

This compound fertilizer uniform granulator, through the cooperation of the screening plate 13 and the vibrating motor 14, allows the defective products produced by granulation to fall through the screen holes on the screening plate 13 into the storage box 15 for storage, so that these materials can be further processed, such as re-crushing and re-screening, to ensure that the materials can be fully utilized and reduce waste.
[0043] Structural Description:
[0044] Support 1: As the supporting structure of the entire granulator, it fixes other components at a certain height and position, ensuring that each component is in a suitable working state, so that the granulator as a whole remains stable and is easy to operate and run.
[0045] Feed hopper 2: Used to store and transport the raw materials of compound fertilizer to be processed, providing a material source for subsequent processing, so that the material can enter each processing stage of the granulator evenly and stably.
[0046] First motor 3: Provides power to the crusher 16, drives the crusher 16 to rotate, thereby initially crushing the large pieces of fertilizer raw materials in the feed hopper 2, cutting them into smaller blocks or granules for further processing.
[0047] The second motor 4 drives the conveying screw 6 to rotate. The rotation of the conveying screw 6 transports the pre-processed material in the cylinder 5 from the feed port 7 to the discharge port 8, realizing the directional movement of the material in the equipment and ensuring that the material can smoothly enter the next processing stage according to the process flow.
[0048] Cylinder 5: Serves as a material conveying channel. It works in conjunction with the conveying screw 6 to convey the material that has been initially crushed by the feed hopper 2. At the same time, the feed inlet 7 and the discharge outlet 8 on its surface are used for the entry and exit of materials, respectively, to ensure that the materials flow within a specific path.
[0049] Conveying screw 6: Rotates inside cylinder 5, using spiral blades to push the material along the axial direction of cylinder 5, realizing quantitative and stable material conveying, controlling the conveying speed and quantity of the material, so that the material can enter the subsequent crushing and screening processes evenly.
[0050] Feed inlet 7: This is the inlet for materials to enter the cylinder 5, allowing the materials that have been initially crushed by the feed hopper 2 to smoothly enter the cylinder 5 for further conveying and processing under the action of the conveying screw 6.
[0051] Discharge port 8: This is the outlet for materials inside cylinder 5. The materials conveyed by the conveying screw 6 are discharged from discharge port 8 and enter the crushing bucket 9 corresponding to discharge port 8 for subsequent crushing and other processing.
[0052] Crushing hopper 9: It receives the material discharged from the discharge port 8 of the cylinder 5 and provides working space for the extrusion roller 12, so that the material is further crushed by the two extrusion rollers 12 in the crushing hopper 9, and the particle size of the material is further reduced to meet the requirements of subsequent granulation.
[0053] Screening box 10: It screens the crushed material to separate the material that does not meet the particle size requirements from the material that does meet the requirements, so as to ensure the uniformity of the final granulation. It is equipped with components such as screening plate 13 to provide a place for screening operation.
[0054] Discharge port 11: Used to discharge materials that meet the requirements after screening in the screening box 10, so that these materials can enter the subsequent granulation process. It is the channel for qualified materials to flow out of the screening box 10.
[0055] Extrusion roller 12: Inside the crushing hopper 9, two extrusion rollers 12 rotate relative to each other, squeezing and crushing the material entering the crushing hopper 9, further refining the material particles, making the material particle size more uniform, and providing material of suitable particle size for subsequent screening and granulation.
[0056] Screening plate 13: Installed inside the screening box 10, it screens the material entering the screening box 10. According to the size of the screen holes, the material is divided into different particle size grades, so that the material that meets the requirements falls through the screen holes, while the material that does not meet the requirements remains on the screening plate 13 for further processing or re-crushing.
[0057] Vibration motor 14: Installed on the lower surface of the screening plate 13, it provides vibration power to the screening plate 13. Through vibration, the material on the screening plate 13 can be more evenly distributed on the screening plate 13, improving screening efficiency and accuracy, preventing material from clogging the screen holes, and enabling the material to be separated according to particle size more quickly and accurately.
[0058] Storage box 15: Used to collect materials that do not meet the requirements after screening or to temporarily store materials during the screening process so that these materials can be further processed, such as re-crushing or re-screening, to ensure that the materials can be fully utilized and reduce waste.
[0059] Crusher 16: Driven by the first motor 3, it performs preliminary crushing on large pieces of material in the feed hopper 2, cutting larger material blocks into smaller blocks or granules, reducing the initial particle size of the material, and creating favorable conditions for subsequent conveying, further crushing and screening processes.
[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
