Description

Technical Field

[0001] This utility model relates to the field of grading and screening technology, and in particular to a biomass pellet fuel grading and screening device. Background Technology

[0002] The field of grading and screening technology mainly involves the technology of classifying and screening solid materials according to their physical properties. Among them, the biomass pellet fuel screening and grading device is a device specifically used for grading the particle size of biomass pellet fuel.

[0003] Existing technologies require manual repackaging, which not only increases the labor intensity and operation time of users, but may also cause fuel particles to spill or become contaminated during the repackaging process, reducing the purity and quality stability of the fuel, and may also lead to fuel particle loss, reducing the effective utilization rate of the fuel. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has the defect of not having an automatic dispensing function, which leads to the disadvantage that manual operation is required for collection and dispensing after biomass pellet fuel screening. To this end, we propose a biomass pellet fuel screening and grading device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a biomass pellet fuel screening and grading device, comprising a base, a housing fixedly connected to the top of the base, a servo motor installed on one side of the housing, a feed hopper installed at one end of the surface of the housing, a spiral drive roller installed at the output end of the servo motor, three screening holes opened at one end of the surface of the housing, three feeding troughs opened inside the base, a holding box slidably connected to the inner wall of the feeding trough, an extension block fixedly connected to one side of the holding box, six clamping blocks rotatably connected to one side of the base via a rotating shaft, one end of the clamping block being inserted into the inner wall of the extension block, a discharge guide rail installed at the other end of the housing, and a collection box placed on one side of the base.

[0006] Preferably, three slot blocks are fixedly connected to one side of the base, and the inner wall of each slot block is slidably connected to a sliding buckle, the inner wall of which is slidably connected to the surface of the clamping block.

[0007] Preferably, a sliding rod is installed inside the groove block, and one end of the sliding rod passes through one side of the sliding buckle and is fixedly connected to one side of the inner wall of the groove block.

[0008] Preferably, a spring is fixedly connected to one side of the sliding buckle, and the other end of the spring is fixedly connected to one side of the inner wall of the groove block.

[0009] Preferably, an installation groove is provided at one end of the inside of the material container, an exhaust fan is installed inside the installation groove, and a screen is installed at one end of the inner wall of the installation groove.

[0010] Preferably, a drying pad is installed inside the container.

[0011] Preferably, both ends of the inner wall of the feeding trough are provided with limiting guide rails, and three rollers are installed on both sides of the bottom of the holding box, with the surface of the rollers slidably connected to the inner wall of the limiting guide rails.

[0012] Technical effects and advantages of this utility model: In this invention, the user releases the sliding buckle, causing the spring to rebound and push the buckle back to its original position. This allows the material container to move out from the inner wall of the limiting guide rail inside the feeding trough via rollers. The particles inside the material container slide down the inner wall of the limiting guide rail under gravity into the external collection container via a spiral drive roller. The material container allows particles of different sizes after screening to automatically fall into the designated collection container, eliminating the need for manual sorting. This reduces the user's labor intensity and operation time, and ensures that the fuel particles are stored neatly and orderly after screening, avoiding fuel spillage and contamination caused by improper manual operation, thus improving the purity and quality stability of the fuel.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a biomass pellet fuel screening and grading device, including a base 1, a housing 2 fixedly connected to the top of the base 1, a servo motor 3 installed on one side of the housing 2, a feed hopper 4 installed at one end of the surface of the housing 2, a screw drive roller 5 installed at the output end of the servo motor 3, three screening holes 6 opened at one end of the surface of the housing 2, three feeding troughs 7 opened inside the base 1, a holding box 8 slidably connected to the inner wall of the feeding trough 7, an extension block 9 fixedly connected to one side of the holding box 8, six clamping blocks 10 rotatably connected to one side of the base 1 via a rotating shaft, one end of the clamping block 10 inserting into the inner wall of the extension block 9, a discharge guide rail 11 installed at the other end of the housing 2, a collection box 12 placed on one side of the base 1, and three [unclear text - possibly related to a servo motor 3 or servo motor 4] fixedly connected to one side of the base 1. The inner wall of the trough 13 is slidably connected to the sliding buckle 14. The inner wall of the sliding buckle 14 is slidably connected to the surface of the clamping block 10. The inside of the trough 13 is equipped with a sliding rod 15. One end of the sliding rod 15 passes through one side of the sliding buckle 14 and is fixedly connected to one side of the inner wall of the trough 13. One side of the sliding buckle 14 is fixedly connected to a spring 16. The other end of the spring 16 is fixedly connected to one side of the inner wall of the trough 13. One end of the inside of the material box 8 is provided with an installation groove 17. An exhaust fan 18 is installed inside the installation groove 17. A screen 19 is installed at one end of the inner wall of the installation groove 17. A drying pad 20 is installed inside the material box 8. Both ends of the inner wall of the discharge trough 7 are provided with limiting guide rails 21. Three rollers 22 are installed on both sides of the bottom of the material box 8. The surface of the rollers 22 is slidably connected to the inner wall of the limiting guide rails 21. Specifically: After the user puts fuel pellets into the housing 2 through the feed hopper 4, the controller drives the equipment, and the servo motor 3 drives the screw drive roller 5 to transmit the pellets to the other end of the housing 2. When the pellets pass through the screening hole 6, the appropriately sized pellets will fall into the storage box 8 through the screen holes of the screening hole 6 and the feeding trough 7. The drying pad 20 installed inside the storage box 8 absorbs and dries the residual moisture on the surface of the pellets, preventing the damp pellets from clumping during subsequent storage or use. The exhaust fan 18 in the installation slot 17 is activated, and the airflow inside the storage box 8 accelerates the drying speed of the pellets after screening. The larger pellets that do not pass through the screening hole 6 continue to move with the screw drive roller 5. Under the guidance of the storage extension block 9, they fall into the collection box 12 through the discharge guide rail 11, realizing the initial classification of different sized pellets. When the storage box 8 is full of pellets, the user moves the sliding buckle 14 along the sliding rod 15 inside the slot block 13. The sliding buckle 14 compresses the spring 16, causing the spring 16 to store and compress. At this time, the clamps 10 at both ends are released, allowing the user to unfold the clamps 10 to the sides, causing the clamps 10 to disengage from the inner wall of the extension block 9. The user then releases the sliding buckle 14, causing the spring 16 to release and push the sliding buckle 14 back to its original position. This allows the material container 8 to move out from the inner wall of the limiting guide rail 21 inside the feeding trough 7 via the roller 22. The particles inside the material container 8 slide down the inner wall of the limiting guide rail 21 under the action of gravity through the spiral drive roller 5 into the external collection container, completing the removal of qualified particles after screening. The material container 8 allows particles of different specifications after screening to automatically fall into the designated collection container without manual sorting, reducing the user's labor intensity and operation time. It also ensures that the fuel particles can be stored neatly and orderly after screening, avoiding fuel spillage and contamination caused by improper manual operation, and improving the purity and quality stability of the fuel.

[0017] Working principle: After the user puts fuel pellets into the housing 2 through the feed hopper 4, the device is started by the controller. The servo motor 3 drives the screw drive roller 5 to convey the pellets to the other end of the housing 2. During the conveying process, when the pellets pass through the screening hole 6, the pellets that meet the specifications will fall into the collection box 8 through the screening hole 6 along the discharge chute 7. The collection box 8 is equipped with a drying pad 20, which can absorb the moisture on the surface of the pellets and prevent the damp pellets from clumping during subsequent storage or use. The exhaust fan 18 in the mounting slot 17 is started, while the larger pellets that do not pass through the screening hole 6 continue to move with the screw drive roller 5. Under the guidance of the extension block 9, they pass through the discharge guide rail 11. The particles fall into the collection box 12, achieving preliminary grading of particles of different specifications. When the collection box 8 is full, the user moves the sliding buckle 14 through the slide rod 15 in the slot block 13, squeezing the spring 16 to compress it and release the restriction of the clamping blocks 10 at both ends. The user unfolds the clamping blocks 10 to both sides, allowing them to disengage from the inner wall of the extension block 9. After releasing the sliding buckle 14, the spring 16 releases and rebounds, pushing the sliding buckle 14 back to its original position. At this time, the collection box 8 moves out along the limiting guide rail 21 in the discharge slot 7 via the roller 22. Under the action of gravity, the particles in the collection box 8 slide down the limiting guide rail 21 into the external collection container, completing the removal of qualified particles after screening.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
