Description

Technical Field

[0001] This utility model relates to the field of crushing equipment, specifically a biomass pellet raw material crusher. Background Technology

[0002] Biomass pellets are a new type of combustion material. They are generally made from combustible waste materials such as straw, wood chips, and corn stalks, which are crushed and then pelletized by a pellet mill. The aim is to recycle and reuse these waste materials, create value, and protect resources.

[0003] When producing biomass pellets, the raw materials need to be crushed, which requires the use of a crusher. However, existing biomass pellet crushers are inconvenient for users to classify the crushed pellets. When crushing raw materials, the size of the crushed materials varies. If the crushing is too fine, it may increase the specific surface area, leading to more air retention, which may affect the pellet formation during pelleting or require more binder. Conversely, if the fragments are too large, they may not be able to be effectively compressed, resulting in loose pellets with insufficient strength. This causes inconvenience for users in crushing raw materials and makes pellet processing difficult after crushing. Utility Model Content

When crushing raw materials, the particles vary in size. If the crushing is too fine, it may increase the surface area, leading to more air retention, which affects pellet formation during granulation or requires more binder. Conversely, if the particles are too large, they may not be effectively compressed, resulting in loose particles with insufficient strength. This causes inconvenience for users in crushing raw materials and hinders pellet processing after crushing. This invention proposes a biomass pellet crusher.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

There are three filter frames 205, and a filter screen 206 is fixedly connected to the inner wall of the filter frame 205. By setting up the layered filtration mechanism 2, users can easily filter the crushed particles in layers when crushing biological raw materials. This allows the filtered raw material fragments to be processed into particles more effectively, avoiding the situation where raw material fragments of different sizes are crushed too finely during particle processing, which would increase the specific surface area and cause more air to be trapped. At the same time, it can also avoid affecting the particle formation during granulation or requiring more adhesive. Conversely, if the fragments are too large, they may not be able to be effectively compressed, resulting in loose particles with insufficient strength. This achieves the purpose of making it easier for users to process raw material fragments into particles.

[0026] Reference Figure 2 The inner wall of the storage box 5 is movably connected with an extrusion plate 7. There are three extrusion plates 7. The top of the extrusion plate 7 is fixedly connected to the output end of the oil cylinder 8. By setting the extrusion plate 7, the crushed raw material fragments can be extruded, increasing the usable space of the storage box 5, thereby storing more raw material fragments and achieving the purpose of extruding the raw material fragments to increase the usable space of the storage box 5.

[0027] Reference Figure 2 Limiting rods 9 are fixedly connected to both sides of the protective door 15, and rotating rods 11 are fixedly connected to both sides of the storage box 5. A clamping plate 10 is rotatably connected to the surface of the rotating rod 11. The inner wall of the clamping plate 10 is in contact with the surface of the limiting rod 9. By setting the limiting rod 9, rotating rod 11 and clamping plate 10 in cooperation, the protective door 15 can be limited, increasing the stability and firmness of the protective door 15 during use, and achieving the purpose of limiting the protective door 15.

[0028] Reference Figure 3 Guide blocks 12 are fixedly connected to both sides of the filter frame 205. The surface of the guide block 12 is slidably connected to the inner wall of the housing 4. By setting the guide block 12, the stability of the filter frame 205 when moving can be increased, and the filter frame 205 can be prevented from shifting when moving, thus achieving the purpose of preventing the filter frame 205 from shifting when moving.

A conveying pipe 13 is fixedly connected to one side of the protective ring 14. One end of the conveying pipe 13 is fixedly connected to one side of the storage box 5. By setting the protective ring 14 and the conveying pipe 13 in cooperation, the raw material fragments stored in the shell 4 can be conveyed, so that the raw material fragments stored in the shell 4 can enter the storage box 5, thus achieving the purpose of conveying the raw material fragments in the shell 4.

[0030] Reference Figure 3A handle 16 is fixedly connected to the top of the filter frame 205. The handle 16 is made of metal. By making the handle 16 a metal material, the life of the handle 16 during use can be increased, thereby making it easier for users to use the filter frame 205. This achieves the purpose of making it easier for users to move the filter frame 205 and increasing the life of the handle 16.

[0031] Working Principle: When crushing raw materials, the user first crushes the raw materials using the biological powder crusher body 1. The crushed raw material fragments are then activated by an external power supply and switch to rotate the first motor 203, causing the fan blades 208 to rotate. The rotating fan blades 208 create a negative pressure in the housing 4, allowing the crushed raw material fragments from the biological powder crusher body 1 to enter the housing 4 through the discharge hopper 3. Since the mesh diameters of the filter screens 206 in the three filter frames 205 are different, the raw material fragments entering the housing 4 first come into contact with the filter screen 206 in the first filter frame 205, performing preliminary filtration on the larger raw material fragments. The smaller raw material fragments then enter the next filter screen 206. Through the layered filtration of the three filter screens 206, the raw material fragments are obtained in three sizes: large, medium, and small. Subsequently, the user sequentially activates the three second motors 201 using an external power supply and switch. The rotation of the three second motors 201 causes the fan blades 208 to rotate, and the rotating fan blades 208 force air through the sealed container 2. 02. The raw material fragments of different sizes are blown into the three areas of the housing 4. After being blown, the raw material fragments are transported into the storage box 5 through the protective ring 14 and the conveying pipe 13. Two partitions are set in the storage box 5, so that there are three different storage areas in the storage box 5. Under the action of the three different areas of the storage box 5, the raw material fragments of different sizes are stored. When the raw material fragments in the storage box 5 reach a certain amount, in order to increase the storage space of the storage box 5, the user starts the hydraulic cylinder 8 through the external power supply and switch. The extension end of the hydraulic cylinder 8 drives the extrusion plate 7 to extrude the raw material fragments stored in the storage box 5. After the storage box 5 stores a certain amount of extruded raw material fragments, the user opens the protective door 15. When opening the protective door 15, the user moves the clamping plate 10, so that the clamping plate 10 rotates around the rotating rod 11. At the same time, the clamping plate 10 pushes and pulls with the limiting plate. Then, the user opens the protective door 15 under the action of the rotating shaft, and the raw material fragments stored in the storage box 5 can be used.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
