[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-7 The present invention provides a biomass fuel extrusion device, comprising:

[0037] The processing tank 1 has a feed inlet 2 at the top and a discharge outlet 3 at the bottom;

[0038] The crushing assembly includes two crushing rollers 4 and a crushing component. The two crushing rollers 4 are rotatably connected to the upper half of the processing tank 1 via a central shaft 5. The crushing component is set in the lower half of the processing tank 1 for mixing and crushing biomass materials.

[0039] The extrusion assembly includes an extrusion tank 6 and an extrusion component. The extrusion tank 6 is fixedly connected to the bottom of the processing tank 1 and communicates with the processing tank 1 through the discharge port 3. The extrusion component is set inside the extrusion tank 6 for extruding biomass.

[0040] The cleaning assembly includes a fixed plate 7, a sealing component, and a cleaning component. The fixed plate 7 is slidably connected to the extrusion tank 6. The sealing component and the cleaning component are both mounted on the fixed plate 7 and are used to seal and clean the outlet end of the extrusion tank 6, respectively.

[0041] The solution is further optimized. The sealing component includes several first storage slots 8 opened on the fixed plate 7. Several sealing tubes 9 are set in the first storage slots 8. The sealing tubes 9 are nested layer by layer. A cylinder 10 is fixedly connected in the first storage slots 8. An adjusting rod 11 is fixedly connected to the telescopic end of the cylinder 10. An adjusting component is set on the adjusting rod 11. The adjusting rod 11 pushes the sealing tubes 9 into the outlet end of the extrusion tank 6 through the adjusting component.

[0042] Reference Figure 2 , Figure 3 The outlet end of the extrusion tank 6 is first sealed by the sealing pipe 9. After sealing, the internal raw material is extruded by the extrusion component to ensure the extrusion effect. The multi-layer sealing pipe 9 is adapted to the outlet end with different hole sizes.

[0043] The scheme is further optimized. The adjusting component includes an adjusting block 12 that is slidably connected to the adjusting rod 11. Several first connecting rods 13 are hinged to one end of the adjusting block 12 along the circumferential direction. Several pushing blocks 14 are slidably connected to one end of the adjusting rod 11 at equal intervals along the circumferential direction. The pushing blocks 14 are hinged to the other end of the first connecting rods 13. Several slots 15 are opened at equal intervals along the circumferential direction on several sealing tubes 9. The pushing blocks 14 are adapted to the slots 15. A first electric telescopic rod 16 is fixedly connected inside the adjusting rod 11. The adjusting block 12 extends into the adjusting rod 11 and is fixedly connected to the output end of the first electric telescopic rod 16.

[0044] Reference Figure 2 , Figure 6 The first electric telescopic rod 16 pushes the adjusting block 12 to move. When the adjusting block 12 moves, the first connecting rod 13 drives the pushing block 14 to extend, thereby docking with the slot 15 on the corresponding sealing tube 9. This is used to push different numbers of sealing tubes 9 into the outlet end, thereby adapting to different sizes of outlets.

[0045] The solution is further optimized. The cleaning component includes several second storage slots 17 on the fixed plate 7. A fixed block 19 is slidably connected to the second storage slot 17 via a second electric telescopic rod 18. Several sliding grooves 20 are provided on the fixed block 19 along the circumference. Several threaded rods 21 are rotatably connected in the sliding grooves 20. A cleaning rod 22 is threadedly connected to the threaded rod 21. The cleaning rod 22 is slidably connected to the sliding groove 20. A first motor 23 is fixedly connected in the fixed plate 7. A first bevel gear 24 is fixedly connected to the output shaft of the first motor 23. One end of the threaded rod 21 extends into the fixed block 19 and is fixedly connected to a second bevel gear 25. The first bevel gear 24 meshes with the second bevel gear 25.

[0046] Reference Figure 3 , Figure 4 The first motor 23 drives several threaded rods 21 to rotate. When the threaded rods 21 rotate, they drive the corresponding cleaning rods 22 to move, so that they can be adapted to the outlet end with different hole sizes. The second electric telescopic rod 18 drives the cleaning rods 22 to extend into the outlet end for cleaning.

[0047] In one embodiment of the present invention, a plurality of first storage slots 8 and a plurality of second storage slots 17 are arranged alternately, and the fixed disk 7 is rotated by a separate motor to achieve the correspondence between the first storage slots 8 and the second storage slots 17 and the outlet end.

[0048] In one embodiment of the present invention, the fixing block 19 rotates by a separate drive motor, thereby causing several cleaning rods 22 to rotate and clean the inside of the outlet end.

[0049] Further optimization of the scheme: the extrusion component includes a hydraulic cylinder 26 fixedly connected to the outer wall of the extrusion tank 6. The telescopic end of the hydraulic cylinder 26 extends into the extrusion tank 6 and is fixedly connected to an extrusion plate 27. The outlet end of the extrusion tank 6 is detachably connected to a discharge plate 28, and the discharge plate 28 is provided with several discharge holes 29.

[0050] Reference Figure 1 The hydraulic cylinder 26 drives the extrusion plate 27 to move, and the extrusion plate 27 extrudes the raw material inside and squeezes it out from the discharge hole 29.

[0051] The further optimized scheme includes a pulverizing component comprising a rotating shaft 30 rotatably connected inside the processing tank 1, a plurality of sliding grooves 31 equally spaced along the axial direction on the rotating shaft 30, a moving ring 32 sleeved on the sliding grooves 31, a plurality of blades 33 fixedly connected along the circumferential direction on the moving ring 32, a second motor 34 fixedly connected to the bottom end of the processing tank 1, and one end of the rotating shaft 30 extending out of the processing tank 1 and fixedly connected to the output shaft of the second motor 34.

[0052] Reference Figure 1The second motor 34 drives the rotating shaft 30 to rotate, and the rotating shaft 30 drives the blade 33 to rotate to further crush the raw materials. At the same time, the sliding groove 31 ensures the vertical movement of the blade 33, and further increases the cutting range of the blade 33 during movement.

[0053] In a further optimized design, several limiting rods 35 are fixedly connected inside the first storage groove 8. The limiting rods 35 are slidably connected to the sealing tube 9. A first spring 36 is sleeved on the limiting rod 35. The two ends of the first spring 36 are fixedly connected to the inner wall of the first storage groove 8 and the sealing tube 9, respectively.

[0054] Reference Figure 2 , Figure 3 The first spring 36 and the limiting rod 35 ensure the stable movement and stable reset of the sealing tube 9. In addition, the first spring 36 ensures that the outer sealing tube 9 is prevented from moving when the inner sealing tube 9 is pushed.

[0055] In a further optimized design, a number of limiting grooves 37 are provided at equal intervals along the circumference of one end of the adjusting rod 11. The pushing block 14 is slidably connected in the limiting groove 37. A second spring 38 is fixedly connected in the limiting groove 37. The two ends of the second spring 38 are fixedly connected to the pushing block 14 and the inner wall of the limiting groove 37, respectively.

[0056] Reference Figure 6 The push block 14 slides within the limiting groove 37, and the second spring 38 ensures the stable reset of the push block 14.

[0057] The scheme was further optimized by fixing several crushing rods 39 on the crushing roller 4.

[0058] Reference Figure 1 The crushing efficiency is improved by setting the crushing rods 39 to operate in an alternating manner.

[0059] A method of using a biomass fuel extrusion device includes the following steps:

[0060] The biomass material is placed into processing tank 1 for crushing;

[0061] The raw materials are placed into the extrusion tank 6 through the feed inlet 2. After placement, they are subjected to primary crushing by the crushing roller 4, and then further crushed by the blades 33.

[0062] The crushed biomass material is transported into the extrusion tank 6. The extrusion tank 6 is first sealed by the sealing component, and then extruded by the extrusion component.

[0063] The crushed raw materials are transported into the extrusion tank 6. The discharge hole 29 is first blocked by the sealing pipe 9. After the blockage, the raw materials inside are extruded to ensure the extrusion pressure, thereby improving the extrusion discharge effect.

[0064] Remove the sealing component and extrude the material from the extrusion tank 6 through the extrusion component;

[0065] The hydraulic cylinder 26 drives the extrusion plate 27 to move, extruding the biomass material from the discharge hole 29.

[0066] After extrusion is completed, the outlet end of the extrusion tank 6 is cleaned using the cleaning components.

[0067] After extrusion, the cleaning rod 22 is inserted into the discharge hole 29 for cleaning to prevent the discharge hole 29 from becoming blocked.
