Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer granulation technology, and more specifically, to an organic fertilizer granulation device. Background Technology

[0002] Organic fertilizer granulation is the process of forming granules from fermented organic materials through extrusion, spheroidization, or polishing to improve fertilizer efficiency and facilitate storage and application. Common granulation methods include rotary granulation, extrusion granulation, and disc polishing. Extrusion granulation forces materials through a die using a screw or roller, making it suitable for materials with high moisture content. Rotary granulation utilizes centrifugal force to roll the material into spheres, resulting in more uniform granules. Optimizing the granulation process can improve granule strength, reduce pulverization, and adapt to the characteristics of different organic raw materials.

[0003] Existing organic fertilizer granulators require multiple processes and multiple sets of equipment to achieve the desired results. In this case, the organic fertilizer raw materials need to be transferred multiple times, which cannot achieve continuous operation between raw materials and granules, thus affecting the granulation effect.

[0004] In addition, most existing organic fertilizer granulators directly discharge organic fertilizer granules during the granulation stage. However, when discharging organic fertilizer granules, they cannot screen some uncompressed and unbonded raw material powders or some unstable and broken granules, resulting in poor granule quality. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides an organic fertilizer granulation device to solve the technical problems mentioned in the background art, such as poor operation continuity of organic fertilizer granulation devices and inability to effectively screen organic fertilizer particles during discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An organic fertilizer granulation device includes a mixing chamber with a feed pipe on one side. Inside the mixing chamber, a rotating shaft is mounted via bearings, and a first motor is mounted in conjunction with the shaft. The rotating shaft is equipped with stirring blades and crushing blades. The interaction of the stirring blades and crushing blades further crushes the organic fertilizer raw materials during the stirring and mixing process, thereby improving the fineness of the material during granulation and enhancing the granulation effect. Preferably, the stirring blades are configured as two sets of counter-rotating spiral blades to improve the thoroughness of stirring and mixing. A [unclear - possibly a device or equipment] is located inside the mixing chamber, below the stirring blades and crushing blades. The first screen is provided at the bottom of the mixing box, and the extrusion section is provided at the bottom of the mixing box. The diameter of the extrusion section is smaller than the internal diameter of the mixing box. In this way, when the material enters the extrusion section from the mixing box, it will be compressed due to the reduced space, thereby improving granulation and compactness. The rotating shaft rotates through the first screen and extends into the extrusion section, and is provided with spiral conveying blades. The bottom of the extrusion section is provided with a granulation plate. The rotating shaft rotates and extends to the bottom of the granulation plate, and is provided with a cutting blade. The bottom of the extrusion section is provided with a discharge box. The discharge box is inclinedly provided with a second screen, and the discharge box is provided with a discharge port in conjunction with the second screen.

[0008] The present invention is further provided with a scraper on the rotating shaft and at the top of the first screen, which can scrape the upper surface of the first screen plate, thereby improving the material falling effect of the first screen.

[0009] The present invention is further configured such that a crushing box is provided on the feed pipe, and two sets of crushing rollers are provided in the crushing box, and a crushing motor is provided in conjunction with the crushing rollers. When the crushing motor is started, the crushing rollers can be rotated by the crushing motor, thereby realizing the automatic crushing of organic fertilizer entering the crushing box, reducing the pressure on the crushing blades in the later stage, and improving the granulation efficiency.

[0010] The present invention is further configured such that a guide plate is provided inside the crushing box, and a feed hopper is provided at the top of the crushing box. The guide plate is used to enhance the crushing effect of the crushing roller on the organic fertilizer raw materials, and the feed hopper is used to improve the convenience of feeding in the crushing box.

[0011] The present invention is further configured such that a feeding pipe is provided on one side of the feeding hopper, and a guide pipe is provided between the bottom end of the feeding pipe and the discharge box. A feeding structure is provided inside the feeding pipe in conjunction with the feeding hopper. The powder screened in the discharge box can be automatically guided to the feeding pipe through the guide pipe, thereby realizing the reuse of the screened powder.

[0012] The present invention is further configured such that the feeding structure includes a spiral feeding shaft, which is installed in the feeding pipe through a bearing, and a feeding motor is connected to the top end for transmission. When the feeding motor is started, the spiral feeding shaft can be rotated, so that the material entering the feeding pipe can be conveyed upward under the action of the spiral feeding shaft and re-enter the feeding hopper as granulation raw material.

[0013] The present invention is further configured such that a feeding port is provided at one end of the feeding pipe connected to the feeding hopper, through which the material in the feeding pipe is re-transported into the feeding hopper.

[0014] The present invention is further provided that the side wall of the mixing box is provided with an inspection door in conjunction with the first screen. The inspection door facilitates the opening of the side wall of the mixing box, thereby facilitating the cleaning of impurities intercepted by the first screen.

[0015] Compared with the prior art, the present invention provides an organic fertilizer granulation device, which has the following beneficial effects:

[0016] 1. In use, this utility model first crushes the primary raw materials of organic fertilizer with the help of crushing rollers, and then conveys them to the mixing box through the feed pipe. Under the action of the first motor, the rotating shaft can be controlled to drive the stirring blades and crushing blades to rotate, thereby realizing the mixing and stirring of the raw materials. During the mixing and stirring process, the raw materials are further crushed, improving the cohesiveness and fineness during subsequent granulation and improving the granulation effect. At the same time, the first screen can screen the raw materials entering the extrusion section, thereby preventing large particles from falling into the granulation and improving the granulation effect.

[0017] 2. Afterwards, the raw materials under the composite conditions will pass through the first screen. During this process, when the rotating shaft rotates, it will drive the spiral conveyor blades to rotate synchronously, thereby conveying the qualified materials in the mixture to the extrusion section. Due to the diameter of the extrusion section, the raw materials will be automatically compressed and compacted after entering the extrusion end. Under the conveying pressure of the spiral conveyor blades, they will pass through the mesh on the granulation plate and be cut by the cutting blades that are also driven by the rotating shaft to form organic fertilizer granules.

[0018] 3. After that, the organic fertilizer granules will fall onto the second screen in the discharge box and be screened through the second screen. This will separate the powdery raw materials or broken and unqualified granules from the organic fertilizer granules and transport them to the feeding pipe through the guide pipe. With the cooperation of the feeding motor and the screw feeding shaft, they can be transported back to the feeding hopper and re-participated in the granulation process. Attached Figure Description

[0036] In summary:

[0037] In use, this utility model first crushes the primary raw materials of organic fertilizer with the help of the crushing roller 17, and then conveys them to the mixing box 1 through the feed pipe 2. Under the action of the first motor 4, the rotating shaft 3 can be controlled to drive the stirring blades 5 and the crushing blades 6 to rotate, thereby realizing the mixing and stirring of the raw materials. During the mixing and stirring process, the raw materials are further crushed, which improves the adhesion and fineness during subsequent granulation and improves the granulation effect. At the same time, the first screen 7 can screen the raw materials entering the extrusion section 8, thereby avoiding the situation where large particles of raw materials fall down and participate in granulation, and improving the granulation effect.

[0038] Afterwards, the raw materials under the composite conditions will pass through the first screen 7. During this process, when the rotating shaft 3 rotates, it will drive the spiral conveyor blades 9 to rotate synchronously, thereby conveying the qualified materials in the mixture to the extrusion section 8. Due to the diameter of the extrusion section 8, the raw materials will be automatically compressed and compacted after entering the extrusion end. Under the conveying pressure of the spiral conveyor blades 9, they will pass through the mesh on the granulation plate 10 and be cut by the cutting blades 11 that are also driven to rotate by the rotating shaft 3 to form organic fertilizer granules.

[0039] Afterwards, the organic fertilizer granules fall onto the second screen 13 inside the discharge box 12 and are screened through the second screen 13. This allows the powdery raw materials or broken and unqualified granules separated from the organic fertilizer granules to be screened out. The granules are then conveyed to the feeding pipe 21 through the guide pipe 22. With the cooperation of the feeding motor 24 and the screw feeding shaft 23, they can be conveyed back to the feeding hopper 20 and re-participated in granulation. In realizing organic fertilizer granulation, this utility model eliminates the need to transfer organic fertilizer raw materials between multiple devices, improving the continuity of granulation. At the same time, it can effectively screen the organic fertilizer granules and allow the screened materials to be re-participated in granulation.
