Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a granulator feeding device. Background Technology

[0002] Pellet mills are core equipment in production lines of industries such as feed, fertilizer, and biomass energy, used to process powdered or mixed raw materials into granular products. The stable operation of a pellet mill and the quality of its products largely depend on the continuous and uniform material supply provided by the upstream feeding device.

[0003] In actual production, raw materials used for pelleting, such as mixed feed and organic fertilizer, often clump together due to factors such as moisture content, storage time, or the characteristics of the materials themselves. When these clumped materials are added to a conventional feeding device (usually a simple feeding hopper), a series of problems arise.

[0004] Larger clumps can get stuck directly in the discharge port below the feed hopper, causing blockages. A more common and troublesome phenomenon is "bridging": under the influence of gravity, materials compress against each other, forming a stable, arch-like structure above the discharge port. This prevents material from falling smoothly, even when the hopper is full, the discharge port has no material to discharge. This situation causes a sudden interruption in the feeding process, causing downstream pellet mills to run idle or produce defective products due to lack of material, severely impacting the continuity and efficiency of the entire production line. Operators often need to frequently break the bridging by manually tapping or using tools to pry the material out, which not only increases labor intensity but also creates safety hazards.

[0005] Therefore, this utility model proposes a pellet mill feeding device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a pellet mill feeding device, which aims to improve the problem that existing pellet mill feeding devices are prone to bridging or blockage in the feed hopper when processing raw materials that are prone to agglomeration, resulting in unstable feeding.

The agitation mechanism includes a stirring roller rotatably connected to the feed hopper. A third gear is fixed to one end of the stirring roller. The third gear meshes with the second gear. This structural combination achieves forced synchronous linkage between the agitation mechanism and the crushing mechanism.

[0018] 2.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1 to 3This utility model provides a pellet mill feeding device, which aims to solve the problem that when the existing pellet mill feeding device processes raw materials that are prone to agglomeration, the material is prone to bridging or blockage in the feeding hopper, resulting in unstable feeding.

[0024] The pellet mill feeding device includes a first support 1 and a second support 3 mounted on the first support 1. The feeding hopper 4 is mounted on the second support 3, and the conveying mechanism 2 is set on the first support 1 and located below the feeding hopper 4, forming the support and material receiving frame of the entire device. The core innovation of the pellet mill feeding device is that the feeding hopper 4 is equipped with a crushing mechanism 6 and a dispersing mechanism 8 that work together, and a driving mechanism 7 is provided to provide unified motion power for the crushing mechanism 6 and the dispersing mechanism 8. Specifically, the overall installation position of the agitation mechanism 8 is located above the crushing mechanism 6. This vertical layout ensures that the raw material must pass through the working area of ​​the agitation mechanism 8 before falling into the crushing mechanism 6. The agitation of the agitation mechanism 8 can effectively disperse the raw material and break the bridging structure that may be formed in the feed hopper 4, thereby ensuring that the raw material can flow smoothly downward to the crushing mechanism 6. The crushing mechanism 6 includes a first crushing roller 601 and a second crushing roller 603 arranged in parallel to each other. Both the first crushing roller 601 and the second crushing roller 603 are rotatably connected to the inner wall of the feed hopper 4 and are used to crush the material falling from above by roller compression. In order to realize the linkage of the two crushing rollers, a first gear 602 is fixedly connected to one end of the first crushing roller 601 and a second gear 604 is fixedly connected to the corresponding end of the second crushing roller 603. The first gear 602 and the second gear 604 mesh with each other for transmission. This meshing relationship ensures that when one crushing roller rotates, the other crushing roller can rotate synchronously in the opposite direction, thereby generating an effective shearing and compression effect on the material. The mixing mechanism 8 includes a mixing roller 801, which is rotatably connected to the feed hopper 4. One end of the mixing roller 801 is fixedly connected to a third gear 802, which directly meshes with the second gear 604 of the crushing mechanism 6. Through this meshing relationship, when the power of the drive mechanism 7 is transmitted to the second gear 604, the power will simultaneously drive the second crushing roller 603, the first crushing roller 601, and the mixing roller 801 to rotate, thereby realizing the forced synchronization and coordinated operation of the two actions of mixing and crushing.

[0025] The drive mechanism 7 includes a second motor 701 as a power source, a first pulley 702 fixed on the output shaft of the second motor 701, and a second pulley 703 that cooperates with the first pulley 702; the second motor 701 is fixedly connected to the upper side of the second bracket 3 to provide power for the entire crushing and dispersing process. In the assembled state, the first pulley 702 is connected to the second pulley 703 via a belt; the second pulley 703 is coaxially fixed to the second crushing roller 603 of the crushing mechanism 6. Thus, when the second motor 701 starts, the power is directly driven to rotate the second pulley 703 through the first pulley 702 and the belt, thereby driving the second crushing roller 603 to rotate. Since the second crushing roller 603 meshes with the first gear 602 and the third gear 802 respectively through the second gear 604, the rotation of the second crushing roller 603 will be converted into the rotation of the first crushing roller 601 and the stirring roller 801 at the same time, thus realizing the synchronous operation of the two functional units of crushing and dispersing with a set of power systems; the belt drive method can also play a certain role in buffering and protection in case of accidental overload. In addition, in order to perform preliminary screening and impurity removal of the raw materials entering the feed hopper 4, a stainless steel grid 5 can be detachably installed on the upper side of the inside of the feed hopper 4. The stainless steel grid 5 can intercept lumps or foreign objects that are too large, preventing these materials from impacting or damaging the crushing mechanism 6 and the agitation mechanism 8 below.

[0026] In a preferred embodiment, in order to efficiently transport the pre-treated material to the subsequent granulation equipment, the conveying mechanism 2 adopts a double-helix conveying structure. The conveying mechanism 2 specifically includes a main conveying cylinder 201 and a secondary conveying cylinder 205. The feed inlet of the secondary conveying cylinder 205 is directly connected to the discharge outlet below the feed hopper 4, and is used to receive the material that has been crushed and dispersed. The main conveying cylinder 201 and the secondary conveying cylinder 205 are arranged in parallel, and the discharge end of the secondary conveying cylinder 205 and the cylinder wall of the main conveying cylinder 201 are opened to communicate with each other, so that the material conveyed from the secondary conveying cylinder 205 can smoothly enter the main conveying cylinder 201.

[0027] To achieve material conveying, the main conveying cylinder 201 is equipped with a main spiral conveying blade 203 that rotates inside, while the auxiliary conveying cylinder 205 is also equipped with an auxiliary spiral conveying blade 206 that rotates inside; this double spiral design can provide a more stable and larger conveying capacity of material flow.

[0028] As a further optimization of the above-mentioned conveying mechanism 2, in order to drive the two spiral conveying blades to work synchronously, the conveying mechanism 2 is also provided with an independent power mechanism; the power mechanism includes a first motor 202 fixed to one side of the main conveying cylinder 201, and the power of the first motor 202 directly drives the main spiral conveying blade 203 to rotate; in order to achieve linkage with the auxiliary spiral conveying blade 206, a driving gear 204 is fixed at one end of the main spiral conveying blade 203, and a driven gear 207 is fixed at the corresponding end of the auxiliary spiral conveying blade 206. The driving gear 204 and the driven gear 207 mesh with each other, thereby transmitting the power of the first motor 202 to the auxiliary spiral conveying blade 206, ensuring the synchronous and efficient operation of the two spiral conveying blades.

[0029] Working principle: When materials need to be pre-processed and conveyed, the raw materials are first added into the feed hopper 4. Large lumps or foreign objects will be intercepted by the top stainless steel grid 5. Then the second motor 701 of the drive mechanism 7 is started. The power of the second motor 701 is transmitted to the second pulley 703 through the first pulley 702 and the belt, driving the second crushing roller 603 to rotate. Since the second crushing roller 603 meshes with the first gear 602 and the third gear 802 through the second gear 604, the rotation of the second crushing roller 603 will force the first crushing roller 601 and the stirring roller 801 to rotate synchronously. The stirring roller 801 located above first stirs the material in the feed hopper 4, effectively breaking the bridging phenomenon of the material and loosening it, ensuring that the material can fall smoothly. The falling material then enters between the first crushing roller 601 and the second crushing roller 603 that rotate in opposite directions, and is effectively squeezed and crushed into smaller particles by the rollers. After the material has completed pretreatment, it falls from the lower discharge port of the feed hopper 4 into the secondary conveying cylinder 205 of the conveying mechanism 2. At this time, the first motor 202 of the conveying mechanism 2 is started. The first motor 202 drives the main spiral conveying blade 203 to rotate, and through the meshing drive gear 204 and driven gear 207, drives the secondary spiral conveying blade 206 to rotate synchronously. The secondary spiral conveying blade 206 pushes the material from the secondary conveying cylinder 205 into the main conveying cylinder 201, and then the main spiral conveying blade 203 steadily conveys the material to the final discharge port for supply to the subsequent pellet mill.
