Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a raw material crushing device for biomass pellet fuel production. Background Technology

[0002] Biofuels refer to energy forms that can replace fossil fuels and are produced using biomass resources. They are mainly fuels produced from biomass such as plants and animal waste through physical, chemical, or biological conversion technologies. Their energy comes from the solar energy fixed by plant photosynthesis. To facilitate use, transportation, and storage, the biomass raw materials are usually produced in pellet form. In the process of biopelle fuel production, the raw materials need to be crushed by a crushing device to facilitate pelleting.

[0003] Currently, when processing straw, it is usually directly fed into the crushing device. Due to the long length of the straw and the high toughness of some plants, the straw often gets tangled with the shaft of the crushing blades during the crushing process. Prolonged tangling can cause significant damage to the crushing device, which usually requires regular cleaning. This results in poor crushing effect of the crushing device and reduces crushing efficiency. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Combination Figures 1 to 5 As shown, the technical solution provided by this utility model is as follows: In this embodiment, a raw material crushing device for biomass pellet fuel production includes: a crushing box 1; a storage box 2, fixedly mounted on the crushing box 1, with the interior of the storage box 2 connected to the interior of the crushing box 1; a mesh cutter 3, slidably mounted inside the storage box 2, capable of being inserted into the interior of the crushing box 1; a driven frame 4, fixedly mounted on the side of the mesh cutter 3; and a hydraulic cylinder 5, fixedly mounted on the storage box 2, wherein when the hydraulic cylinder 5 is extended, the driven frame 4 descends, thereby causing the mesh cutter... The blade 3 extends deep into the crushing box 1; a baffle structure is set inside the crushing box 1 to block the material; a crushing structure is set inside the crushing box 1, with the crushing structure located directly below the baffle structure. A hydraulic cylinder 5 is provided, which can cooperate with the driven frame 4 to drive the grid cutter 3 to move and cut the material, avoiding excessively long straw from affecting subsequent crushing work. The grid cutter 3 is assembled from longitudinally and transversely arranged cutters, which can cut all the straw at the same time. The space formed between the cutters determines the cutting length of the straw.

[0023] Combination Figure 1 , Figure 2 and Figure 5As shown, it also includes: a drying chamber 12, fixedly installed at the bottom of the crushing chamber 1, with the interior of the drying chamber 12 connected to the interior of the crushing chamber 1; a rotating shaft 13, rotatably installed inside the drying chamber 12; a reduction motor 14, fixedly installed on the drying chamber 12, with the output end of the reduction motor 14 connected to the shaft end of the rotating shaft 13 for transmission; and a tilting plate 15, fixedly installed on the rotating shaft 13, with the surface of the tilting plate 15 in contact with the inner surface of the drying chamber 12. By setting the tilting plate 15, the material can be continuously tilted and lifted during the rotation of the rotating shaft 13, ensuring that the material is in full contact with the hot air, thereby significantly improving the drying effect of the material.

[0024] Combination Figure 1 , Figure 2 and Figure 5 As shown, it also includes: a hot air box 16, which is fixedly installed on the drying box 12 and is connected to the inside of the drying box 12; and a sealing door 17, which is hinged at the discharge port of the drying box 12. By setting the hot air box 16, hot air can be continuously supplied to the inside of the drying box 12, so that the material can be fully heated and dried. By setting the sealing door 17, it is convenient to discharge the material.

[0025] Combination Figure 1 , Figure 3 and Figure 4 As shown, it also includes: a feed hopper 9, which is connected to the side of the crushing box 1 and is located above the material blocking structure; a sealing plate 10, which is slidably disposed on the feed hopper 9 and is used to seal the discharge port of the feed hopper 9. By setting the sealing plate 10, it is possible to prevent the material from being ejected from the feed hopper 9 due to excessive shearing force during the cutting process.

[0026] It also includes: a positioning plate 20, which is fixedly installed inside the feed hopper 9, and the sealing plate 10 is slidably installed on both sides inside the positioning plate 20; and several guide rods 11, which are fixedly installed inside the storage box 2, with the outer surface of the guide rods 11 movably inserted into the inside of the grid cutter 3. By setting the positioning plate 20, the sealing plate 10 can be limited to improve its stability. By setting the guide rods 11, the grid cutter 3 can be guided to prevent it from tilting during the cutting process, and the material in the gap can be pushed out during the resetting process of the grid cutter 3, so as to achieve the effect of automatic feeding.

[0027] Combination Figure 3 As shown, the baffle structure includes: two baffle plates 6, which are rotatably disposed inside the crushing box 1; and several support cylinders 7, which are rotatably disposed on the inner side wall of the crushing box 1. The other ends of the several support cylinders 7 are respectively rotatably disposed with the surfaces of the two baffle plates 6. The support cylinders 7 are located below the baffle plates 6 and are tilted in a sealed state.

[0028] Combination Figures 1 to 3As shown, the crushing structure includes: two crushing rollers 8, which are rotatably disposed inside the crushing box 1 and cooperate with each other; a drive motor 19, which is fixedly disposed on the crushing box 1 and whose output end is connected to the shaft end of one of the crushing rollers 8; and two transmission gears 18, which are fixedly disposed on the other end of the crushing roller 8 and mesh with each other.

[0029] This utility model provides a raw material crushing device for biomass pellet fuel production, the specific working principle of which is as follows:

[0030] During the straw crushing process, the operator first feeds the straw into the crushing box 1 through the feed hopper 9. Then, the crushing box 1 is sealed with the sealing plate 10. Next, the hydraulic cylinder 5 is activated, which pushes the driven frame 4 downward, causing the grid cutter 3 to gradually approach the material. Under the pressure applied by the hydraulic cylinder 5, the straw is cut. When the grid cutter 3 contacts the surface of the baffle plate 6, the straw is completely cut. The above mechanism cuts all the straw into small pieces, effectively preventing the straw from getting tangled in the shaft during subsequent crushing, thus ensuring the stable operation of the crushing device and significantly improving the crushing efficiency.

[0031] Subsequently, the hydraulic cylinder 5 resets, driving the grid cutter 3 into the storage box 2. During this process, the guide rod 11 pushes out the cut material inside the grid cutter 3. Under the action of gravity, the material accumulates again on the baffle plate 6. Then, the support cylinder 7 retracts, driving the baffle plate 6 to open. Under the action of gravity, the material falls between the two crushing rollers 8. The crushing rollers 8 crush the straw under the drive of the drive motor 19. The crushed material falls into the drying box 12 for collection.

[0032] Once the crushed straw has accumulated to a certain amount, the reduction motor 14 starts, driving the turning plate 15 on the rotating shaft 13 to rotate. The turning plate 15 continuously turns the material, causing the crushed material to constantly turn inside the drying chamber, which facilitates full contact between the hot air delivered by the hot air box and the material, thus improving the drying efficiency. After drying is completed, the operator opens the sealing door 17 and, pushed by the turning plate 15, pushes the dried material out of the drying chamber 12 for collection and storage.

[0033] 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.
