Description

Technical Field

[0001] The present invention relates to the technical field of biomass composite fuel processing, and particularly to a biomass fuel preparation device. Background Art

[0002] Biomass fuel is a renewable clean energy source, mainly made from organic substances (such as plants, crop residues, wood waste, animal manure, etc.) through biological or thermochemical conversion processes. Through preparation equipment, biomass raw materials can be processed into high-density, high-calorific value fuels, such as biomass pellet fuels or block fuels. This kind of fuel can release more energy during the combustion process, improving energy utilization efficiency.

[0003] When the existing biomass fuel preparation equipment presses biomass materials into briquette blocks, it generally compresses the biomass materials in the mold by the downward movement of a pressing plate.

[0004] When the existing biomass fuel preparation equipment is in use, since the particle sizes and shapes of biomass fuels are diverse, during the process of biomass fuel falling into a cylindrical mold, it will cause uneven initial distribution of materials in the mold. When the pressing plate presses the unevenly distributed materials, it will cause uneven stress on the biomass fuel in the mold, resulting in problems such as local looseness or inconsistent density;

[0005] Moreover, biomass materials will come from agricultural wastes such as straw or rice husks and other materials. During the collection process of these raw materials, soil will be mixed in. When the soil and biomass fuel enter the mold, when the pressing plate compresses and forms the soil and biomass fuel, the soil will adhere to the lower part of the pressing plate, causing a change in the size of the pressing plate. When subsequent compression molding of biomass fuel is carried out, it is difficult to achieve uniform pressing of biomass fuel, and it will cause the shape of the pressed biomass block to be irregular and the size to be inaccurate, thereby resulting in problems such as a decrease in the density and a weakening of the strength of the pressed biomass block. Summary of the Invention

[0006] The purpose of the present invention is to propose a biomass fuel preparation device to solve the problems of uneven stress during material pressing and the adhesion of soil under the pressing plate, resulting in irregular shape and inaccurate size of the pressed biomass block.

[0024] Further description of a biomass fuel preparation device of the above technology:

[0025] The feeding component includes an electromagnetic valve fixedly connected to the housing. One end of the electromagnetic valve is fixedly connected to a discharge pipe. The other end of the electromagnetic valve is fixedly connected to a hopper. A feeding port is provided on the hopper.

[0026] Further description of a biomass fuel preparation device of the above technology:

[0027] A spiral blade is rotatably connected inside the hopper. A stirring rod is fixedly connected to the spiral blade. The rotating ends of the spiral blade and one end of the transmission rod are both fixedly connected with sprockets. The two sprockets are connected by a chain.

[0028] In summary, due to adopting the above technology for a biomass fuel preparation device, the beneficial effects of the present invention are:

[0029] 1. By providing a rotating plate and a pressing plate, the rotating plate drives the mold to rotate intermittently, causing the mold to drive the biomass fuel to move under the pressing plate. The pressing plate moves into the mold and presses down on the biomass fuel inside the mold, squeezing the biomass fuel into a coal ball shape. Subsequently, the rotating plate drives the formed biomass fuel to fall into the discharge port and can be discharged from the housing, enabling the automatic pressing of the biomass fuel into coal ball blocks and achieving efficient production of biomass fuel forming.

[0030] 2. By providing a transmission component, when the fixed rod drives the first rotating rod to descend, the limiting block slides in the limiting groove and slides on the second vertical section, causing the pressing plate to enter the mold. Subsequently, the limiting block slides in the spiral section, causing the first rotating rod to drive the pressing plate to rotate when descending through the moving rod. The shearing force generated by the rotation of the pressing plate distributes the material more evenly in the mold, reducing problems such as local looseness or inconsistent density. Subsequently, the limiting block moves into the first vertical section, and the pressing plate continues to apply pressure to the biomass fuel, making the biomass fuel evenly dense in the mold and further improving the density and strength of the fuel block.

[0031] 3. By providing a one-way meshing mechanism, when the pressing plate resets, the pressing plate is squeezed by the scraper, causing the pressing plate to slide above the scraper. Therefore, when the pressing plate resets, it rotates, contacts the scraper below it, and cleans the impurities below it through the scraper, avoiding the situation where there is soil in the biomass fuel. The soil contacts and adheres to the lower part of the pressing plate. Over time, when the pressing plate descends, more biomass fuel and soil accumulate, making it difficult for the pressing plate to evenly press the biomass fuel, resulting in irregular shapes and inaccurate sizes of the pressed biomass blocks, and thus causing problems such as reduced density and weakened strength of the pressed biomass blocks.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figures 1 - 11 shown, the present invention provides a biomass fuel preparation device, which includes a bottom plate 1 and a reduction motor 7 fixedly connected to the bottom plate 1. A preparation assembly 30 is arranged on the bottom plate 1. The preparation assembly 30 includes a housing 31 fixedly connected to the bottom plate 1. A driving assembly 20 and a forming assembly 40 are arranged inside the housing 31. The preparation assembly further includes a fixing plate 32 fixedly connected inside the housing 1. A discharge port 321 is arranged on the fixing plate 32. A rotating plate 33 that rotates intermittently through the driving assembly 20 is arranged on the fixing plate 32. A plurality of molds 331 are fixedly connected inside the rotating plate 33;

[0052] As Figures 4 to 6 shown, the forming assembly 40 includes a moving plate 41. The moving plate 41 is reciprocally slidably connected to the inner wall of the housing 31 through the driving assembly 20. A fixing rod 42 is fixedly connected inside the moving plate 41. A first rotating rod 46 is rotationally connected inside the fixing rod 42 through a transmission assembly. A moving rod 48 is rotatably and slidably arranged inside the first rotating rod 46. One end of the moving rod 48 is fixedly connected to a pressing plate 43. A connecting rod 49 is rotationally connected inside the fixing rod 42 through a one-way rotating mechanism. One end of the connecting rod 49 is fixedly connected to a scraping plate 491.

[0053] As Figures 4 to 6 shown, the transmission assembly includes a fixing tube 45 fixedly connected inside the fixing rod 42. One end of the fixing tube 45 is rotationally connected to one end of the first rotating rod 46. The transmission assembly further includes a limiting rod 44 fixedly connected to the inner wall of the housing 31. The limiting rod 44 is slidably connected to the inside of the moving plate 41. A limiting groove 47 is arranged inside the first rotating rod 46. A limiting block 441 is slidably connected to the inside of the limiting groove 47. The limiting block 441 is fixedly connected to one end of the limiting rod 44. The limiting groove 47 includes a first vertical section 471. A spiral section 472 is arranged on one side of the first vertical section 471. A second vertical section 473 is arranged on one side of the spiral section 472.

[0054] Specifically, when the existing biomass fuel preparation device presses biomass materials into briquette blocks, it is generally compressed by the lowering of the pressing plate 43 on the biomass materials in the mold 331;

[0055] When the existing biomass fuel preparation equipment is in use, due to the different particle sizes and shapes of biomass fuels, during the process of biomass fuels falling into the cylindrical mold 331, the initial distribution of materials in the mold 331 will be uneven. When the pressing plate 43 presses down on the unevenly distributed materials, the biomass fuels in the mold 331 will be unevenly stressed, resulting in problems such as local looseness or inconsistent density.

[0056] To solve this problem, the present device is used as follows: When the biomass material falls inside the mold 331, the mold 331 intermittently rotates to the pressing plate 43 through the rotating plate 33. At this time, the moving plate 41 drives the fixed rod 42 to descend, the fixed rod 42 drives the fixed pipe 45 to descend, the fixed pipe 45 drives the first rotating rod 46 to descend, the limiting groove 47 on the first rotating rod 46 descends. At the same time, the first rotating rod 46 drives the moving rod 48, the pressing plate 43 and the scraping plate 491 to descend synchronously. The limiting block 441 on the limiting rod 44 slides in the limiting groove 47. Initially, the limiting block 441 is in the second vertical section 473 of the limiting groove 47. The limiting block 441 slides in the second vertical section 473 of the limiting groove 47. At this time, the pressing plate 43 moves into the inside of the mold 331 and contacts the biomass material. Subsequently, the limiting block 441 slides from the second vertical section 473 to the spiral section 472. When the limiting block 441 slides in the spiral section 472, while the first rotating rod 46 drives the pressing plate 43 to descend, it also drives the pressing plate 43 to rotate synchronously. When the pressing plate 43 presses the biomass material, it also drives the biomass material to rotate. The shear force generated by the rotation of the pressing plate 43 makes the materials more evenly distributed in the mold 331. And the centrifugal force generated when the pressing plate 43 rotates makes the materials have an outward diffusion trend in the mold 331, which helps to fill the corners and edge areas of the mold 331, reducing local accumulation or vacancy. Subsequently, the limiting block 441 moves from the spiral section 472 to the first vertical section 471, and the pressing plate 43 continues to apply pressure to the biomass fuel, making the biomass fuel evenly compact in the mold 331, further improving the density and strength of the fuel block.

[0057] By driving the pressing plate 43 to descend and rotate, the present device can continuously change the position of its edge contact points, making the pressure more evenly transmitted to each part of the materials, which helps to reduce problems such as local looseness or inconsistent density. At the same time, the shear force generated by the rotation can break the adhesion and agglomeration between material particles, promoting the rearrangement and mixing of materials in the mold 331, and further improving the uniformity of material distribution.

[0058] Such as Figure 6As shown, an extrusion rod 481 is fixedly connected to the inner wall of the moving rod 48. A convex block 493 is fixedly connected to the connecting rod 49. A second spring 482 is fixedly connected between the inner walls of the moving rod 48 and the first rotating rod 46. One end of the extrusion rod 481 is in contact with the lower surface of the convex block 493. One side of both the scraping plate 491 and the pressing plate 43 is provided as an inclined surface.

[0059] As Figure 7 shown, the one-way rotation mechanism includes a ratchet wheel 492 fixedly connected to the connecting rod 49. A ratchet pawl 451 is rotatably connected to the inside of the fixed pipe 45 through a first spring 452. The ratchet pawl 451 and the ratchet wheel 492 are engaged when the pressing plate 43 rotates back to its original position.

[0060] Specifically, when the pressing plate 43 extrudes and forms the biomass material, since the biomass material comes from agricultural wastes such as straw or rice husks, etc., soil will be mixed in during the collection process of these raw materials. The soil and the biomass fuel enter the mold 331. When the pressing plate 43 compresses and forms the soil and the biomass fuel, the soil will adsorb under the pressing plate 43, causing a change in the size of the pressing plate 43. As a result, when subsequently compressing and forming the biomass fuel, it is difficult to uniformly press the biomass fuel, and the shape of the pressed biomass block is irregular and the size is inaccurate, thus resulting in a decrease in the density and a weakening of the strength of the pressed biomass block.

[0061] To avoid the above problems, the device is used as follows. When the first rotating rod 46 drives the pressing plate 43 at one end of the moving rod 48 to descend and rotate, the pressing plate 43 drives the scraping plate 491 to rotate synchronously. The scraping plate 491 drives the connecting rod 49 to rotate synchronously. The connecting rod 49 drives the ratchet wheel 492 to rotate synchronously. At this time, the ratchet wheel 492 extrudes the ratchet pawl 451, causing the ratchet pawl 451 to rotate and compress the first spring 452, and it will not limit the ratchet wheel 492. At the same time that the moving rod 48 drives the extrusion rod 481 to rotate, the connecting rod 49 drives the convex block 493 to rotate synchronously. The convex block 493 extrudes and limits the extrusion rod 481. The pressing plate 43 can drive the scraping plate 491 to perform a downward pressing operation on the biomass material, and by the convex block 493 extruding and limiting the extrusion rod 481, the pressing plate 43 will not move towards the moving rod 48;

[0062] When the pressing plate 43 resets, at this time, through the cooperation of the ratchet wheel 492 and the pawl 451, the limit is maintained, so that the connecting rod 49 cannot rotate, and the connecting rod 49 drives the scraper 491 to be fixed. Also, since one side of both the pressing plate 43 and the scraper 491 is inclined, when the pressing plate 43 rotates, it squeezes the scraper 491, causing the pressing plate 43 to move above the scraper 491. The pressing plate 43 drives the moving rod 48 to move synchronously, so that the moving rod 48 slides inside the first rotating rod 46 and squeezes the second spring 482. The moving rod 48 rotates to drive the pressing rod 481 to rotate from the convex surface of the convex block 493 to the flat surface. Subsequently, during the rotation of the pressing plate 43, the scraper 491 can clean the soil below the pressing plate 43. When the limiting block 441 moves to the second vertical section 473, the pressing rod 481 slides to the convex surface of the convex block 493, and the pressing rod 481 drives the moving rod 48 to descend and stretch the second spring 482. The moving rod 48 drives the pressing plate 43 to descend and contact the scraper 491, and then the automatic cleaning operation of the soil below the pressing plate 43 can be completed;

[0063] The driving assembly 20 drives the fixed rod 42 and the pressing plate 43 to descend. The pressing plate 43 cooperates with the transmission assembly, so that the pressing plate 43 rotates in the mold 331 when descending. When the pressing plate 43 resets, through the one-way rotation mechanism, the pressing plate 43 moves above the scraper 491, and the pressing plate 43 can rotate above the scraper 491 and clean the area below it.

[0064] In this device, when the pressing plate 43 rises, the scraper 491 contacts the lower part of the pressing plate 43, so that when the pressing plate 43 rotates and resets, it can automatically clean the soil below it, avoiding the situation where the biomass fuel contains soil, the soil contacts and adheres to the lower part of the pressing plate 43. After a long time, when the pressing plate 43 descends, more biomass fuel and soil accumulate, resulting in difficulty for the pressing plate 43 to uniformly press the biomass fuel, and the shape of the pressed biomass block is irregular and the size is inaccurate, thus causing a decrease in the density and a weakening of the strength of the pressed biomass block.

[0065] As Figures 8 to 9 shown, the output end of the reduction motor 7 is connected to the driving assembly 20. The driving assembly 20 includes a transmission rod 21 rotatably connected inside the housing 31. One end of the transmission rod 21 is fixedly connected to the output end of the reduction motor 7. A first gear 212 is fixedly connected to the transmission rod 21. A second gear 24 is rotatably connected to the inner wall of the housing 31. The first gear 212 and the second gear 24 mesh with each other. The rotating end of the second gear 24 is fixedly connected to a rotating arm 241. The rotating end of the rotating plate 33 is fixedly connected to a sheave 242.

[0066] Specifically, turn on the reduction motor 7. The reduction motor 7 drives the transmission rod 21 to rotate. The transmission rod 21 drives the first gear 212 to rotate. The first gear 212 meshes with the second gear 24, causing the second gear 24 to drive the swing arm to rotate. The swing arm rotates and toggles the sprocket 242, causing the sprocket 242 to drive the rotating plate 33 to rotate intermittently.

[0067] As Figure 3 shown, the drive assembly 20 further includes a first bevel gear 211 fixedly connected to the transmission rod 21. The inner wall of the housing 31 is rotatably connected to a second rotating rod 23. A second bevel gear 231 and a turntable 232 are fixedly connected to the second rotating rod 23. The first bevel gear 211 and the second bevel gear 231 mesh with each other. One side of the turntable 232 is rotatably connected to a connecting rod 233. One end of the connecting rod 233 is rotatably connected to the moving plate 41.

[0068] Specifically, the transmission rod 21 rotates and drives the first bevel gear 211 to rotate. The first bevel gear 211 meshes with the second bevel gear 231, causing the second bevel gear 231 to drive the second rotating rod 23 to rotate. The second rotating rod 23 drives the turntable 232 to rotate. The turntable 232 drives the moving plate 41 at one end of the connecting rod 233 to move reciprocally.

[0069] As Figure 1 、 Figure 10 and Figure 11 shown, the housing 31 is provided with a feeding assembly 60. The feeding assembly 60 includes a solenoid valve 63 fixedly connected to the housing 31. One end of the solenoid valve 63 is fixedly connected to a discharge pipe 64. The other end of the solenoid valve 63 is fixedly connected to a hopper 61. The hopper 61 is provided with a feeding port 62. A spiral blade 65 is rotatably connected inside the hopper 61. A stirring rod 66 is fixedly connected to the spiral blade 65. The rotating ends of the spiral blade 65 and one end of the transmission rod 21 are both fixedly connected with a sprocket 213. The two sprockets 213 are connected by a chain drive.

[0070] Specifically, the biomass fuel enters the hopper 61. The transmission rod 21 drives the spiral blade 65 to rotate through the sprocket 213. The spiral blade 65 drives the stirring rod 66 to rotate. When the mold 331 rotates below the discharge pipe 64, the solenoid valve 63 is opened, causing the biomass material in the hopper 61 to fall into the inside of the mold 331.

[0071] As Figure 2 shown, an inclined plate 34 is fixedly connected inside the housing 31. A discharge plate 35 is fixedly connected to one side of the housing 31. The discharge plate 35 is inclined.

[0072] When the biomass material in the mold 331 is pressed into blocks, the rotating plate 33 drives the block material to rotate on the fixed plate 32, and the material rotates to the discharge port 321. The pressing plate 43 descends to push the material from the discharge port 321 to the inclined plate 34, and then slides to the discharge plate 35 through the inclined plate 34 for collection and processing.

[0073] Working principle: First, put the material into the hopper 61, then turn on the reduction motor 7, the reduction motor 7 drives the transmission rod 21 to rotate, the transmission rod 21 drives the spiral blade 65 to rotate through the sprocket 213, the spiral blade 65 drives the stirring rod 66 to rotate, and at the same time, the transmission rod 21 drives the first gear 212 to rotate, the first gear 212 and the second gear 24 are meshed, so that the second gear 24 drives the swing arm to rotate, the swing arm rotates and dials the groove wheel 242, so that the groove wheel 242 drives the rotating plate 33 to rotate intermittently, and the rotating plate 33 drives the mold 331 to rotate to discharge the material. At the bottom of the tube 64, the solenoid valve 63 is opened at this time, so that the biomass material in the hopper 61 falls into the interior of the mold 331, and then the solenoid valve 63 is closed, and the swing arm moves the groove wheel 242 again, so that the rotating plate 33 drives the mold 331 to rotate to the pressing plate 43, the transmission rod 21 rotates and drives the first bevel gear 211 to rotate, the first bevel gear 211 and the second bevel gear 231 are meshed, so that the second bevel gear 231 drives the second rotating rod 23 to rotate, the second rotating rod 23 drives the rotating disk 232 to rotate, and the rotating disk 232 drives the moving plate 41 at one end of the connecting rod 233 to descend;

[0074] The movable plate 41 drives the fixed rod 42 to descend, the fixed rod 42 drives the fixed tube 45 to descend, the fixed tube 45 drives the first rotating rod 46 to descend, the limiting groove 47 on the first rotating rod 46 descends, and at the same time, the first rotating rod 46 drives the movable rod 48, the pressing plate 43 and the scraper 491 to descend synchronously, and the limiting block 441 on the limiting rod 44 slides in the limiting groove 47. In the initial state, the limiting block 441 is in the second vertical section 473 of the limiting groove 47, and the limiting block 441 slides in the second vertical section 473 in the limiting groove 47. At this time, the pressing plate 43 moves to the inside of the mold 331 and contacts the biomass material, and then the limiting block 441 slides from the second vertical section 473 to the spiral section 472. When the limit block 441 slides in the spiral section 472, the first rotating rod 46 drives the pressing plate 43 to descend and drives the pressing plate 43 to rotate synchronously. The pressing plate 43 squeezes the biomass material and drives the biomass material to rotate. The shear force generated by the rotation of the pressing plate 43 makes the material more evenly distributed in the mold 331. Then the limit block 441 moves from the spiral section 472 to the first vertical section 471. The pressing plate 43 continues to apply pressure to the biomass fuel, making the biomass fuel evenly dense in the mold 331, further improving the density and strength of the fuel block;

[0075] When the first rotating rod 46 drives the pressing plate 43 at one end of the moving rod 48 to descend and rotate, the pressing plate 43 drives the scraper 491 to rotate synchronously. The scraper 491 drives the connecting rod 49 to rotate synchronously, and the connecting rod 49 drives the ratchet 492 to rotate synchronously. At this time, the ratchet 492 presses the pawl 451, causing the pawl 451 to rotate and press the first spring 452, without limiting the ratchet 492. Moreover, when the moving rod 48 drives the pressing rod 481 to rotate, the connecting rod 49 drives the convex block 493 to rotate synchronously, and the convex block 493 presses and limits the pressing rod 481. The pressing plate 43 can drive the scraper 491 to perform a pressing operation on the biomass material. And by the convex block 493 pressing and limiting the pressing rod 481, the pressing plate 43 will not move towards the direction of the moving rod 48;

[0076] When the pressing plate 43 resets, at this time, through the cooperation of the ratchet 492 and the pawl 451 to maintain the limit, the connecting rod 49 cannot rotate, and the connecting rod 49 drives the scraper 491 to be fixed. Also, because both sides of the pressing plate 43 and the scraper 491 are inclined, when the pressing plate 43 rotates, it presses the scraper 491, causing the pressing plate 43 to move above the scraper 491. The pressing plate 43 drives the moving rod 48 to move synchronously, causing the moving rod 48 to slide inside the first rotating rod 46 and press the second spring 482. The moving rod 48 rotates and drives the pressing rod 481 to rotate from the convex surface of the convex block 493 to the flat surface. Subsequently, during the rotation of the pressing plate 43, the scraper 491 can clean the soil below the pressing plate 43. When the limiting block 441 moves to the second vertical section 473, the pressing rod 481 slides to the convex surface of the convex block 493, and the pressing rod 481 drives the moving rod 48 to descend and stretch the second spring 482. The moving rod 48 drives the pressing plate 43 to descend and contact the scraper 491, and then the automatic cleaning operation of the soil below the pressing plate 43 can be completed;

[0077] The pressed material rotates again following the rotating plate 33. The rotating plate 33 drives the material to the discharge port 321 at the fixed plate 32. Another set of pressing plates 43 descend to push the material onto the inclined plate 34. The material slides on the inclined plate 34 to the discharge plate 35 and is discharged, and then can be collected and processed.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
