Abstract
Description
Technical Field
[0001] This utility model relates to the field of pellet forming technology, and in particular to a biomass pellet forming and granulation equipment. Background Technology
[0002] Biomass pellets are a renewable energy source made from agricultural and forestry waste through cold-forming densification. They are characterized by high combustion efficiency and zero sulfur and phosphorus emissions. The raw materials include straw, forestry residues, etc. In the biomass pellet processing, the raw materials (such as branches, rice straw, etc.) need to be crushed before extrusion molding. However, due to the variety of raw materials, their hardness, size, and fiber structure vary significantly (for example, branches are hard, while rice straw is tough and easy to entangle). Existing crushing processes often face problems such as uneven particle size and insufficient fiber tearing. This not only leads to poor material flowability and incomplete mold filling in the subsequent pelleting process, but also seriously affects the density, molding rate, and surface smoothness of the pellets. In addition, the current crushing and pelleting processes are mostly operated by independent equipment in separate steps. The crushed material needs to be transferred through intermediate transfers before entering the pellet mill, which not only increases dust pollution and energy consumption, but also significantly restricts the overall production efficiency and continuity due to process interruption. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a biomass pellet forming and granulation equipment.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a biomass pellet forming and granulation equipment, including a crushing barrel, a crushing component is provided inside the crushing barrel and the crushing frame, the crushing component includes a first sliding groove opened inside the crushing barrel, a first slider is slidably connected inside the first sliding groove, a rotating disk is fixedly connected to the side of the first slider away from the first sliding groove, the rotating disk has a plurality of first rotating rods rotatably connected to its top, each of the plurality of first rotating rods has a meshing crushing roller fixedly connected to its surface, the crushing component includes a gear plate disposed inside the crushing barrel, a gear meshing with the gear plate is fixedly connected to the top of the first rotating rod, the crushing component includes a motor box disposed at the bottom of the crushing barrel, a motor is fixedly connected inside the motor box, and a second rotating rod is fixedly connected to the drive shaft of the motor.
[0005] As a preferred embodiment of the present invention, the end of the second rotating rod away from the drive shaft passes through the motor housing and the crushing barrel in sequence and extends into the interior of the crushing barrel, and the end of the second rotating rod extending into the interior of the crushing barrel is fixedly connected to the rotating disk.
[0006] As a preferred technical solution of this utility model, a cutting assembly is provided inside the crushing barrel and at the bottom of the rotating disk. The cutting assembly includes a threaded sleeve disposed on the surface of the first rotating rod, and an extrusion plate is fixedly connected to the outside of the threaded sleeve.
[0007] As a preferred technical solution of this utility model, the cutting component includes a second sliding groove disposed on both sides of the crushing barrel, a second slider is slidably connected inside the second sliding groove, and the end of the second slider away from the second sliding groove is fixedly connected to the extrusion plate.
[0008] As a preferred embodiment of the present invention, the cutting assembly includes a discharge cover disposed at the bottom of the crushing barrel, and a plurality of blades are fixedly connected to the top of the discharge cover.
[0009] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. This utility model, through the setting of the crushing barrel and crushing components, when it is necessary to crush biomass raw materials, the motor drives the rotating disk on the first rotating rod to rotate, the rotating disk drives the crushing roller to revolve, and at the same time, due to the cooperation of the gear plate and the gear, the crushing roller rotates on its own axis. When the biomass raw materials fall between the crushing rollers, the crushing rollers rotate on their own axis and revolve on their own axis to more thoroughly crush the biomass raw materials, avoiding the impact on the shape and density of subsequent pelleting due to insufficient crushing.
[0010] 2. This utility model, through the arrangement of the crushing barrel, the first rotating rod, and the cutting assembly, allows the first rotating rod to rotate and drive the extrusion plate on the threaded sleeve to reciprocate up and down through the cooperation of the second sliding groove and the second slider when the crushed raw material falls onto the discharge cover. The reciprocating motion of the extrusion plate causes the extrusion block to squeeze the raw material on the blade, allowing the raw material to enter the gap between the blades. At the same time, the extrusion block and the extrusion blades cut the raw material, squeezing it into granules. This avoids the need to transport the cut raw material back to the granulation device, reducing transportation time and improving work efficiency. Attached Figure Description

Detailed Implementation
[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0014] Example: This utility model provides, for example Figure 1 , Figure 2 , Figure 4 and Figure 5 The diagram shows a biomass pelletizing and granulation equipment, including a crushing barrel 1. A crushing assembly 2 is disposed inside the crushing barrel 1 and a crushing frame. The crushing assembly 2 includes a first chute 21 formed inside the crushing barrel 1. A first slider 22 is slidably connected inside the first chute 21. A rotating disk 23 is fixedly connected to the side of the first slider 22 away from the first chute 21. A plurality of first rotating rods 24 are rotatably connected to the top of the rotating disk 23. Each of the first rotating rods 24 has a meshing crushing roller 25 fixedly connected to its surface. The crushing assembly 2 also includes a gear plate 26 disposed inside the crushing barrel. The top of the moving rod 24 is fixedly connected to a gear 27 that meshes with the gear plate 26. The crushing assembly 2 includes a motor housing 28 located at the bottom of the crushing barrel 1. A motor 29 is fixedly connected inside the motor housing 28. The motor 29 is a servo motor, with the reference model number SD130AEA26025-SH3. The drive shaft of the motor 29 is fixedly connected to a second rotating rod 201. The end of the second rotating rod 201 away from the drive shaft passes through the motor housing 28 and the crushing barrel 1 and extends into the interior of the crushing barrel 1. The end of the second rotating rod 201 extending into the interior of the crushing barrel 1 is fixedly connected to the rotating disk 23.
[0015] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the worker places the raw material into the crushing drum 1, and then starts the motor 29. The motor 29 drives the second rotating rod 201 to rotate. When the second rotating rod 201 rotates, the rotating disk 23 rotates through the cooperation of the first sliding groove 21 and the first sliding block 22. The rotation of the rotating disk 23 drives the first rotating rod 24 to rotate on the rotating disk 23. When the first rotating rod 24 rotates on the rotating disk 23, the gear 27 on the first rotating rod 24 drives the second rotating rod 201 to rotate through the gear plate 26. This causes the crushing roller 25 to not only revolve around the rotating disk 23 but also rotate on its own axis, so that the raw material is crushed more thoroughly when it falls between the crushing rollers 25.
[0016] refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a cutting assembly 3 is provided inside the crushing barrel 1 and at the bottom of the rotating disk 23. The cutting assembly 3 includes a threaded sleeve 31 provided on the surface of the first rotating rod 24. An extrusion plate 32 is fixedly connected to the outside of the threaded sleeve 31. The surface of the extrusion plate 32 is sloped to facilitate the crushed raw material falling onto the discharge cover 35. The cutting assembly 3 includes a second sliding groove 33 provided on both sides of the crushing barrel 1. A second slider 34 is slidably connected inside the second sliding groove 33. The end of the second slider 34 away from the second sliding groove 33 is fixedly connected to the extrusion plate 32. The cutting assembly 3 includes a discharge cover 35 provided at the bottom of the crushing barrel 1. The inner ring of the discharge cover 35 is sloped so that the raw material falling onto the discharge cover 35 gathers towards the middle of the discharge cover 35. Several blades 36 are fixedly connected to the top of the discharge cover 35.
[0017] refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the crushed raw material falls onto the discharge cover 35. At the same time, due to the rotation of the second rotating rod 201, the threaded sleeve 31 moves up and down on the second rotating rod 201 through the cooperation of the second sliding groove 33 and the second slider 34. The threaded sleeve 31 drives the extrusion plate 32 to move back and forth, while the extrusion block 37 extrudes the crushed raw material on the discharge cover 35. At the same time, the blades cut the crushed raw material, so that the crushed raw material is squeezed into pellets in the gap between the blades 36 on the discharge cover 35. Then, the workers rotate the discharge cover 35 to take out the biomass pellets.
[0018] Working principle: Before use: refer to Figure 1 As shown, the staff put the raw materials into the crushing barrel 1.
[0019] When using: refer to Figure 1 , Figure 2 , Figure 4and Figure 5 As shown, motor 29 is then started, which drives the second rotating rod 201 to rotate. When the second rotating rod 201 rotates, the rotating disk 23 rotates through the cooperation of the first sliding groove 21 and the first slider 22. The rotation of the rotating disk 23 drives the first rotating rod 24 to rotate on the rotating disk 23. When the first rotating rod 24 rotates on the rotating disk 23, the gear 27 on the first rotating rod 24 drives the second rotating rod 201 to rotate through the gear plate 26. This causes the crushing roller 25 to not only revolve around the rotating disk 23 but also rotate on its own axis. When the raw material falls between the crushing rollers 25, it is crushed more thoroughly. The crushed raw material falls onto the discharge cover 35.
[0020] After use: refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the rotation of the second rotating rod 201 causes the threaded sleeve 31 to reciprocate up and down on the second rotating rod 201 through the cooperation of the second sliding groove 33 and the second slider 34. While the threaded sleeve 31 drives the extrusion plate 32 to reciprocate, the extrusion block 37 extrudes the crushed raw material on the discharge cover 35. At the same time, the blades cut the crushed raw material, so that the crushed raw material is extruded into pellets in the gap between the blades 36 on the discharge cover 35. Then, the workers rotate the discharge cover 35 to take out the biomass pellets.
[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
