Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a biomass pellet drying equipment. Background Technology

[0002] Biomass pellet drying equipment is used to remove moisture from biomass raw materials to ensure the quality and efficiency of subsequent processing. It uses a drum dryer to evaporate moisture by contacting a rotating drum with hot air, and is suitable for various biomass raw materials such as pellets and powders.

[0003] A search of Chinese patent CN219890045U reveals a biomass pellet drying device with good drying effect. The device includes a drying chamber with multiple support legs fixedly installed on it. A material hopper is also fixedly installed on the drying chamber and connected to it. A motor is fixedly installed on the top side of the drying chamber, and a drying conveying structure is installed at the motor's output end. Two limiting strips are symmetrically fixedly installed on the drying chamber. This invention, through the design of the motor, spiral blades, and arc-shaped screen, allows biomass pellets to be poured into the drying chamber through the material hopper. Starting the hot air blower delivers hot air into the drying chamber to dry the biomass pellets. Simultaneously, starting the motor rotates the spiral blades and conveys the biomass pellets, allowing them to roll on the arc-shaped screen, thereby removing debris and residue from the biomass pellets, separating the residue from the finished product, and improving the overall quality of the finished product.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When biomass pellets are fed, some biomass pellets may not be fed smoothly and may easily remain on the feeding plate. Furthermore, when changing the loading and feeding container, it is impossible to intercept the fed biomass pellets. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biomass pellet drying device.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a biomass pellet drying device, including a frame, a cylinder fixedly mounted on the frame, a drive motor mounted on the frame, a first roller fixedly mounted on the output end of the drive motor, a second roller movably mounted on the frame, a belt movably mounted between the first roller and the second roller, a shaft fixedly mounted on the second roller, a stirring frame adapted to the inner wall of the cylinder fixedly mounted on the shaft, and a blocking mechanism provided on the frame;

[0008] The blocking mechanism includes two limiting frames symmetrically fixedly installed on the frame. Each limiting frame is threaded with a fixing bolt. A side block is movably installed between the limiting frame and the fixing bolt. A fixing block is fixedly installed on the side block. A support rod is movably installed on the fixing block. A central block is fixedly installed between the two support rods. A handle is movably installed on the central block. A scraper is fixedly installed on the handle.

[0009] The frame is equipped with a scraping mechanism.

[0010] Furthermore, a feed cover is rotatably installed at the top of the cylinder, and a discharge cover is rotatably installed at the bottom of the cylinder.

[0011] Furthermore, a feeding plate adapted to the scraper is fixedly installed on the frame.

[0012] Furthermore, a first spring is connected to the central block, and an annular piece fixed to the handle is connected to the end of the first spring.

[0013] Furthermore, two plate frames adapted to the scraper are symmetrically fixedly installed on the frame.

[0014] Furthermore, the scraping mechanism includes a third roller movably mounted on the frame, and the third roller abuts against the belt, with a long rod fixedly mounted on the third roller.

[0015] Furthermore, the scraping mechanism also includes a housing fixedly mounted on the long rod, and a plurality of second springs are connected to the housing. The ends of the plurality of second springs are connected to a telescopic plate adapted to the housing.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] 1. In this utility model, the drive motor rotates, causing the third roller to rotate via a long rod, which in turn causes the housing to rotate via a second spring. When the telescopic plate contacts the feeding plate, it can scoop up the biomass pellets on the feeding plate, thus facilitating the feeding process. After feeding is completed, the scraper is controlled by the handle to clean up any remaining biomass pellets on the feeding plate, preventing them from remaining on the feeding plate.

[0018] 2. In this utility model, when the container for loading biomass pellets is full, the fixing bolt is unscrewed from the inside of the limiting frame, so that the scraper moves into the inside of the two plate frames, so that the scraper can seal the outlet of the feeding plate and prevent the biomass pellets from falling. After the loading container is replaced, the scraper is moved out of the plate frame, which facilitates the replacement of the loading container and ensures smooth feeding.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 5As shown, an embodiment of this utility model provides a biomass pellet drying device, including a frame 1, a cylinder 2 fixedly installed on the frame 1, a drive motor 3 fixedly installed on the frame 1, a first roller 4 fixedly installed on the output end of the drive motor 3, a second roller 6 movably installed on the frame 1, a belt 5 movably installed between the first roller 4 and the second roller 6, a shaft 7 fixedly installed on the second roller 6, a stirring frame 8 adapted to the inner wall of the cylinder 2 fixedly installed on the shaft 7, a feed cover 9 rotatably installed at the top of the cylinder 2, a discharge cover 10 rotatably installed at the bottom of the cylinder 2, and a discharge plate 11 adapted to the scraper 21 fixedly installed on the frame 1;

[0028] In this embodiment of the utility model, the operator opens the feed cover 9, pours the biomass pellets to be dried into the inside of the cylinder 2, closes the feed cover 9, controls the drive motor 3 to run, so that the output end of the drive motor 3 rotates to drive the first roller 4 to rotate, so that the first roller 4 can drive the second roller 6 to rotate through the belt 5, so that the second roller 6 drives the stirring frame 8 through the shaft 7 to stir the biomass pellets in the cylinder 2, and the biomass pellets are dried by the dryer connected inside and outside the cylinder 2. After drying, the loading container is placed at the outlet of the discharge plate 11, the discharge cover 10 is opened, and the biomass pellets are moved into the loading container through the discharge cover 10 and the discharge plate 11.

[0029] Figures 1 to 5 As shown, a blocking mechanism is provided on the frame 1. The blocking mechanism includes two limiting frames 12 symmetrically fixedly installed on the frame 1. Each limiting frame 12 is threaded with a fixing bolt 13. A side block 14 is movably installed between the limiting frame 12 and the fixing bolt 13. A fixing block 15 is fixedly installed on the side block 14. A support rod 16 is movably installed on the fixing block 15. A center block 17 is fixedly installed between the two support rods 16. A handle 20 is movably installed on the center block 17. A scraper 21 is fixedly installed on the handle 20. A first spring 18 is connected to the center block 17. The end of the first spring 18 is connected to a ring piece 19 fixed to the handle 20. Two plate frames 27 adapted to the scraper 21 are symmetrically fixedly installed on the frame 1.

[0030] In this embodiment of the invention, when the container for loading biomass pellets is full, the fixing bolt 13 is unscrewed from the inside of the limiting frame 12, so that the scraper 21 moves into the inside of the two plate frames 27, so that the scraper 21 can close the outlet of the feeding plate 11 and prevent the biomass pellets from falling. After the loading container is replaced, the scraper 21 is moved out of the plate frame 27 and fixed with the fixing bolt 13, thereby facilitating the replacement of the loading container and ensuring smooth feeding.

[0031] Figures 1 to 5As shown, a scraping mechanism is provided on the frame 1. The scraping mechanism includes a third roller 22 movably mounted on the frame 1, and the third roller 22 abuts against the belt 5. A long rod 23 is fixedly mounted on the third roller 22. The scraping mechanism also includes a housing 24 fixedly mounted on the long rod 23. A plurality of second springs 25 are connected to the housing 24. The ends of the plurality of second springs 25 are connected to a telescopic plate 26 adapted to the housing 24.

[0032] In this embodiment of the invention, the drive motor 3 rotates, causing the first roller 4 to drive the third roller 22 to rotate via the belt 5. The third roller 22 then drives the housing 24 to rotate via the long rod 23. The housing 24 then drives the telescopic plate 26 to rotate via the second spring 25. The second spring 25 supports the telescopic plate 26 with its own elasticity. When the telescopic plate 26 contacts the feeding plate 11, it can scoop up the biomass pellets on the feeding plate 11, thus facilitating the feeding process. After feeding is completed, the operator controls the scraper 21 to move via the handle 20. The handle 20 drives the support rod 16 to rotate via the center block 17, allowing the scraper 21 to clean the remaining biomass pellets on the feeding plate 11 and prevent them from remaining on the feeding plate 11. When the handle 20 is released, the first spring 18 uses its own elasticity to drive the handle 20 to reset via the ring plate 19.

[0033] Working principle: The operator opens the feed cover 9 and pours the biomass pellets to be dried into the inside of the cylinder 2. The feed cover 9 is then closed, and the drive motor 3 is turned on. The output of the drive motor 3 rotates, which drives the first roller 4 to rotate. The first roller 4 then drives the second roller 6 to rotate via the belt 5. The second roller 6 drives the stirring frame 8 via the shaft 7 to stir the biomass pellets in the cylinder 2. The biomass pellets are dried by the dryer connected inside and outside the cylinder 2. After drying, the loading container is placed at the outlet of the discharge plate 11, and the discharge cover 10 is opened, allowing the biomass pellets to move into the loading container through the discharge cover 10 and the discharge plate 11.

[0034] During the feeding process, the drive motor 3 operates, causing the third roller 22 to rotate via the long rod 23, which in turn causes the housing 24 to rotate. The housing 24 then rotates via the second spring 25, causing the telescopic plate 26 to rotate. When the telescopic plate 26 contacts the feeding plate 11, it can scoop up the biomass pellets on the feeding plate 11, thus facilitating the feeding process. After the feeding is completed, the operator controls the scraper 21 via the handle 20 to clean the remaining biomass pellets on the feeding plate 11.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
