[0002] The granulation device in biomass fuel production is mainly used to process raw biomass materials (such as wood chips, straw, wheat straw, corn straw, etc.) into granular fuels of uniform specifications. Such particles are called biomass pellets or biomass fuel pellets.

[0003] When pressing biomass into pellets, the falling pellets may be of different lengths. Longer biomass pellets may not burn completely, and short pellets may cause unstable flames or uneven combustion during the combustion process, which will affect the operational stability and efficiency of the combustion equipment and cause waste of resources. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a granulation device for biomass fuel production, including a granulation assembly, the granulation assembly includes a shell, a feed inlet is opened on the top of the shell, a motor is fixedly connected to the bottom of the inner wall of the shell, and also includes: A feeding assembly, the feeding assembly comprises an extension rod arranged inside the shell, a material placement plate is fixedly connected to the top of the extension rod, and a feeding port is opened on the top of the material placement plate; The discharging assembly comprises a connecting rod arranged inside the shell, an inclined filter plate is fixedly connected to the bottom of the connecting rod, and a discharging port is opened on the right side of the shell.

[0005] Preferably, the output end of the motor is fixedly connected to a rotating shaft, the inner wall of the shell is fixedly connected to a fixed disk, the inner wall of the rotating shaft is fixedly connected to a driving rod, the outer surface of the rotating shaft is rotatably connected to the inner wall of the fixed disk, the outer surface of the driving rod is rotatably connected to a pressing roller, the bottom of the pressing roller is in contact with the top of the fixed disk, and the outer surface of the rotating shaft is fixedly connected to a cutting knife. By setting the cutting knife and keeping the rotation speed of the cutting knife consistent with that of the pressing roller, the particles can be cut more evenly, avoiding uneven or incomplete broken particles.

[0006] Preferably, the bottom of the extension rod is fixedly connected to the top of the rotating shaft, the outer surface of the material placing plate is rotatably connected to the inner wall of the outer shell, the top of the material placing plate is fixedly connected to gear rod 1, the right side of gear rod 1 is meshingly connected to gear rod 2, the bottom of gear rod 2 is meshingly connected to a gear sleeve rod, and the outer surface of the gear sleeve rod is rotatably connected to a shielding box, and by setting the shielding box, the internal structure thereof can be shielded and protected to prevent being affected by biomass raw materials.

[0007] Preferably, the second outer surface of the gear rod is rotatably connected to the inner wall of the baffle box, the left and right sides of the baffle box are fixedly connected to support plates, the two support plates are fixedly connected to the inner wall of the outer shell at the ends away from each other, the outer surface of the gear sleeve rod is fixedly connected to a stirring rod, the bottom of the stirring rod is fixedly connected to a thin rod, and the bottom of the placing plate is fixedly connected to a connecting plate. By arranging the thin rod, it can be prevented that a large amount of raw materials will fall into the discharge port whenever the stirring rod is about to overlap with the discharge port during the stirring process, making the discharge of the discharge port uneven.

[0008] Preferably, the outer surface of the connecting plate is rotatably connected to the inner wall of the outer shell, a swivel is fixedly connected to the bottom of the connecting plate, the outer surface of the swivel is rotatably connected to the inner wall of the outer shell, a bump is fixedly connected to the top of the swivel, a ball is in contact with the top of the swivel, and the outer surface of the ball is rotatably connected to the fixed plate. By setting the ball, sliding can be changed to rolling to reduce friction.

[0009] Preferably, a filter plate is fixedly connected to the bottom of the fixed plate, a limiting protrusion is slidably connected to the outer surface of the filter plate, the limiting protrusion is fixedly connected to the inner wall of the outer shell, the outer surface of the filter plate is slidably connected to the inner wall of the outer shell, a spring is fixedly connected to the top of the filter plate, the top of the spring is fixedly connected to the outer surface of the extension rod, and a material taking port is provided on the front side of the outer shell. By arranging the spring, a buffering effect can be played on the spring when the filter plate rises and compresses the spring, thereby eliminating small and irregular jitters generated by the filter plate and reducing noise generation.

[0010] Preferably, the top of the connecting rod is fixedly connected to the bottom of the filter plate, the outer surface of the inclined filter plate is slidably connected to the inner wall of the outer shell, the outer surface of the rotating shaft is fixedly connected to a baffle plate, and a return port is opened on the left side of the outer shell. By setting the inclined filter plate, the fallen debris can be separated from the particles to prevent the debris and particles from being mixed and discharged.

[0011] A granulation method of a granulation device for biomass fuel production comprises the following steps: S1: When using the device, first move the device to a designated position, then put the biomass raw material into the shell through the feed port, then start the motor to drive the pressing roller to rotate, roll and press the biomass raw material, and finally cut it off by the cutting knife; S2: The raw materials put into the feeding port will first fall on the top of the material placement plate and accumulate. As the material placement plate rotates, the raw materials falling from the feeding port will evenly fall on the top of the filter plate, and the raw materials passing through the filter plate will evenly fall on the top of the fixed plate; S3: The placing plate will also cause the filter plate to vibrate during the rotation process, and the vibration of the filter plate will also cause the inclined filter plate to vibrate. The particles falling on the top of the inclined filter plate will be discharged from the discharge port along the inclined surface of the inclined filter plate through the shaking of the inclined filter plate.

[0012] The present invention has the following beneficial effects: (1) The present invention starts a motor to drive the rotating shaft to rotate. During the rotation of the rotating shaft, the driving rod and the cutting knife are driven to rotate together. The driving rod drives the pressing roller to rotate. During the rotation of the pressing roller, due to the friction between the pressing roller and the fixed plate, the pressing roller rotates with the driving rod as the axis, and then the biomass raw material falling on the top of the fixed plate is crushed. The crushed raw material enters the through hole opened in the fixed plate. As the pressing roller continues to crush, the raw material entering the through hole is pressed into a long strip and exposed from the bottom of the fixed plate. When the length of the exposed long strip is long enough, it will be cut and knocked down by the rotating cutting knife. This design allows the raw material to be cut by the cutting knife after it is pressed out a certain distance, thereby improving the consistency of the generated particles and preventing the particles from being unable to maintain the uniformity of length by free fracture when being pressed out. The rotation speed of the cutting knife is consistent with that of the pressing roller, so that the particles can be cut more evenly and avoid uneven or incompletely broken particles.

[0013] (2) The raw materials put into the feed inlet of the present invention will first fall on the top of the material loading plate and accumulate. When the rotating shaft rotates, it will also drive the material loading plate to rotate through the extension rod. When a large amount of raw materials accumulate on the top of the material loading plate, it is difficult for the material loading plate to rotate together with the raw materials. At this time, the raw materials on the material loading plate will fall into the discharge port and fall out from its bottom. As the material loading plate rotates, the raw materials falling from the discharge port will evenly fall on the top of the filter plate, and the raw materials passing through the filter plate will evenly fall on the top of the fixed plate. During the rotation process, the material loading plate will drive the gear rod 2 to rotate through the gear rod 1, and the gear rod 2 will drive the stirring rod to rotate through the gear sleeve rod. When the stirring rod rotates, it will stir the raw materials accumulated at the higher part of the top of the material loading plate. The material is stirred to prevent agglomeration, and the rotation direction of the stirring rod is opposite to that of the loading plate, which can further prevent the loading plate from driving the raw material to rotate, and the stirring rod will also drive the thin rod to rotate when rotating, thereby preventing the material contacted by the top of the loading plate from being blocked and agglomerated, and the provision of a plurality of thin rods can prevent a large amount of raw material from falling into the loading port whenever the stirring rod is about to overlap with the loading port during the stirring process, causing uneven discharge from the loading port. The above design can discharge the biomass raw material evenly, prevent the raw material from falling on the top of the fixed plate from accumulating uneven thickness, making the speed of extruding particles non-uniform, resulting in different lengths of cutting by the cutting knife, and failure to maintain uniformity of particle length.

[0014] (3) The material placement plate of the present invention will also drive the rotating ring to rotate through the connecting plate during the rotation process. The rotating ring will drive the four protrusions to rotate together during the rotation process. When the protrusion rotates to contact the bottom of the ball, as the protrusion continues to rotate, the ball will be pushed up. The upward push of the ball will drive the filter plate to move upward together through the fixed plate. When the ball is separated from the protrusion, the filter plate will fall. As the rotating ring continues to rotate, the above process will be repeated, thereby achieving a shaking effect on the filter plate. By setting a spring, the filter plate can be buffered when the filter plate rises and compresses the spring, which can eliminate the small amplitude and irregular shaking of the filter plate and reduce the generation of noise. The staff can collect and recycle the filtered raw materials from the material taking port. This design can filter the biomass raw materials falling on it by setting the filter plate, preventing the incompletely crushed wood chips in the raw materials from falling on the fixed plate and being pressed into the through holes opened therein to block it. In addition, the shaking effect of the filter plate can improve the filtering efficiency while preventing the filter plate itself from being blocked.

[0015] (4) The particles produced after being cut by the cutting knife of the present invention will fall on the top of the inclined filter plate, and the filter plate will also drive the inclined filter plate to shake together through the connecting rod during the up and down shaking process. The particles falling on the top of the inclined filter plate will be discharged from the discharge port along the inclined surface of the inclined filter plate due to the shaking action of the inclined filter plate, and the dust debris falling with the particles will pass through the inclined filter plate and fall to the bottom of the inner wall of the shell. The shielding plate can shield the fallen debris to prevent the motor from being affected. The staff can recycle the fallen debris from the return port. This design can separate the fallen debris from the particles and prevent the debris from being mixed with the particles and discharged, thereby ensuring that the quality of the biomass particles finally produced is pure without a large amount of debris or impurities mixed in.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 3 The present invention is a granulation device for biomass fuel production, including a granulation component 1, the granulation component 1 includes a shell 101, a feed inlet 102 is opened at the top of the shell 101, a motor 103 is fixedly connected to the bottom of the inner wall of the shell 101, and also includes: The feed assembly 2 includes an extension rod 201 disposed inside the housing 101, a material placement plate 202 is fixedly connected to the top of the extension rod 201, and a feed opening 203 is provided on the top of the material placement plate 202; The discharging assembly 3 includes a connecting rod 301 arranged inside the shell 101 , an inclined filter plate 302 is fixedly connected to the bottom of the connecting rod 301 , and a discharging port 303 is opened on the right side of the shell 101 .

[0021] The output end of the motor 103 is fixedly connected to a rotating shaft 104, the inner wall of the housing 101 is fixedly connected to a fixed disk 105, the inner wall of the rotating shaft 104 is fixedly connected to a driving rod 106, the outer surface of the rotating shaft 104 is rotatably connected to the inner wall of the fixed disk 105, the outer surface of the driving rod 106 is rotatably connected to a pressing roller 107, the bottom of the pressing roller 107 is in contact with the top of the fixed disk 105, and the outer surface of the rotating shaft 104 is fixedly connected to a cutting knife 108. The motor 103 is started to drive the rotating shaft 104 to rotate, and the rotating shaft 104 will drive the driving rod 106 and the cutting knife 108 to rotate together during the rotation process, and the driving rod 106 will drive the pressing roller 107 to rotate. During the rotation process, the pressing roller 107 will rotate with the driving rod 106 due to the friction between it and the fixed disk 105. The roller 107 is a material roller that is used to press the raw materials. The roller 107 is used to press the raw materials into the through hole formed in the fixed disk 105. The raw materials are pressed into a long strip and exposed from the bottom of the fixed disk 105. When the exposed long strip is long enough, it is cut and knocked off by the rotating cutter 108. This design uses the cutter 108 to cut the raw materials after they are pressed out for a certain distance, thereby improving the consistency of the generated particles and preventing the particles from being pressed out without being able to maintain the uniformity of their length. The rotation speed of the cutter 108 is consistent with that of the press roller 107, so that the particles are cut more evenly and uneven or incomplete particles are avoided.

[0022] For example 2, please refer to Figure 4 - Fig. 9 The present invention is a granulating device for biomass fuel production. On the basis of the first embodiment, the bottom of the extension rod 201 is fixedly connected to the top of the rotating shaft 104, the outer surface of the material placing plate 202 is rotatably connected to the inner wall of the shell 101, the top of the material placing plate 202 is fixedly connected to the gear rod 1 204, the right side of the gear rod 1 204 is meshedly connected to the gear rod 205, the bottom of the gear rod 205 is meshedly connected to the gear sleeve rod 206, the outer surface of the gear sleeve rod 206 is rotatably connected to the shielding box 207, the raw materials put into the feed port 102 will first fall on the top of the material placing plate 202 and accumulate, the rotating shaft 104 is rotating. When the feeding plate 202 moves, the extension rod 201 will also drive the feeding plate 202 to rotate. When a lot of raw materials are accumulated on the top of the feeding plate 202, it is difficult for the feeding plate 202 to drive the raw materials to rotate together. At this time, the raw materials on the feeding plate 202 will fall into the discharge port 203 and fall out from its bottom. As the feeding plate 202 rotates, the raw materials falling from the discharge port 203 will evenly fall on the top of the filter plate 216, and the raw materials passing through the filter plate 216 will evenly fall on the top of the fixed disk 105. During the rotation process, the feeding plate 202 will drive the gear rod 2 205 to rotate through the gear rod 1 204.

[0023] The outer surface of the gear rod 205 is rotatably connected to the inner wall of the shielding box 207. The left and right sides of the shielding box 207 are fixedly connected to support plates 208. The two support plates 208 are fixedly connected to the inner wall of the shell 101 at the ends away from each other. The outer surface of the gear sleeve rod 206 is fixedly connected to a stirring rod 209. The bottom of the stirring rod 209 is fixedly connected to a thin rod 210. The bottom of the material placing plate 202 is fixedly connected to a connecting plate 211. The gear rod 205 will drive the stirring rod 209 to rotate through the gear sleeve rod 206. When the stirring rod 209 rotates, it will stir the materials accumulated at the higher part of the top of the material placing plate 202 to prevent agglomeration. The rotation direction of the stirring rod 209 is opposite to the rotation direction of the material placing plate 202. , which can further prevent the loading plate 202 from driving the raw material to rotate, and the stirring rod 209 will also drive the thin rod 210 to rotate when rotating, thereby preventing the material contacted by the top of the loading plate 202 from being blocked and agglomerated, and by setting a plurality of thin rods 210, it can be prevented that during the stirring process, whenever the stirring rod 209 is about to overlap with the discharge port 203, a large amount of raw material will be driven into the discharge port 203, causing uneven discharge from the discharge port 203. The above design can discharge the biomass raw material evenly, prevent the raw material from falling on the top of the fixed plate 105 from accumulating unevenly, making the speed of pressing out particles non-uniform, resulting in the cutting knife 108 cutting different lengths during cutting, and unable to maintain the uniformity of particle length.

[0024] The outer surface of the connecting plate 211 is rotatably connected to the inner wall of the shell 101, and a swivel 212 is fixedly connected to the bottom of the connecting plate 211. The outer surface of the swivel 212 is rotatably connected to the inner wall of the shell 101, and a protrusion 213 is fixedly connected to the top of the swivel 212. The top of the swivel 212 contacts with a ball 214, and the outer surface of the ball 214 is rotatably connected to a fixed plate 215. The placing plate 202 will also drive the swivel 212 to rotate through the connecting plate 211 during the rotation process. The swivel 212 will drive the four protrusions 213 to rotate together during the rotation process. When the protrusion 213 rotates to contact with the bottom of the ball 214, as the protrusion 213 continues to rotate, the ball 214 will be pushed upward.

[0025] A filter plate 216 is fixedly connected to the bottom of the fixed plate 215, and a limiting protrusion 217 is slidably connected to the outer surface of the filter plate 216. The limiting protrusion 217 is fixedly connected to the inner wall of the shell 101, and the outer surface of the filter plate 216 is slidably connected to the inner wall of the shell 101. A spring 218 is fixedly connected to the top of the filter plate 216, and the top of the spring 218 is fixedly connected to the outer surface of the extension rod 201. A material taking port 219 is provided on the front of the shell 101. The ball 214 is pushed up and the filter plate 216 is driven to move upward through the fixed plate 215. When the ball 214 is separated from the protrusion 213, the filter plate 216 will fall. As the rotating ring 212 continues to rotate, the above process will be repeated. The filter plate 216 has a shaking effect, and by setting the spring 218, when the filter plate 216 rises and compresses the spring 218, it can play a buffering role, thereby eliminating the small and irregular shaking of the filter plate 216 and reducing the noise generation. The staff can collect and recycle the filtered raw materials from the material taking port 219. This design can filter the biomass raw materials falling thereon by setting the filter plate 216, and prevent the incompletely crushed wood chips in the raw materials from falling on the fixed plate 105 and being pressed into the through holes opened therein to block it. In addition, through the shaking effect of the filter plate 216, while improving the filtering efficiency, it can also prevent itself from being blocked.

[0026] The top of the connecting rod 301 is fixedly connected to the bottom of the filter plate 216, the outer surface of the inclined filter plate 302 is slidably connected to the inner wall of the shell 101, the outer surface of the rotating shaft 104 is fixedly connected with a shielding plate 304, and a return port 305 is opened on the left side of the shell 101. The particles produced after being cut by the cutting knife 108 will fall on the top of the inclined filter plate 302, and the filter plate 216 will also drive the inclined filter plate 302 to shake together through the connecting rod 301 during the up and down shaking process, and the particles falling on the top of the inclined filter plate 302 will pass through the shaking effect of the inclined filter plate 302. The dust and debris that fall along the inclined surface of the inclined filter plate 302 are discharged from the discharge port 303, and the dust and debris that fall along with the particles will pass through the inclined filter plate 302 and fall to the bottom of the inner wall of the shell 101. The shielding plate 304 can shield the fallen debris to prevent the motor 103 from being affected. The staff can recycle the fallen debris from the return port 305. This design can separate the fallen debris from the particles and prevent the debris and particles from being mixed and discharged, thereby ensuring that the final produced biomass particles are of pure quality without a large amount of debris or impurities mixed in.

[0027] The granulation method of the granulation device for biomass fuel production comprises the following steps: S1: When using the device, first move the device to a designated position, then put the biomass raw material into the housing 101 through the feed port 102, then start the motor 103 to drive the pressing roller 107 to rotate, and then roll and press the biomass raw material, and finally cut it off by the cutter 108; S2: The raw materials put into the feed port 102 will first fall on the top of the material placement plate 202 and accumulate. As the material placement plate 202 rotates, the raw materials falling from the discharge port 203 will evenly fall on the top of the filter plate 216, and the raw materials passing through the filter plate 216 will evenly fall on the top of the fixed plate 105; S3: The placing plate 202 will also drive the filter plate 216 to vibrate during the rotation, and the shaking of the filter plate 216 will also drive the inclined filter plate 302 to vibrate. The particles falling on the top of the inclined filter plate 302 will be discharged from the discharge port 303 along the inclined surface of the inclined filter plate 302 due to the shaking of the inclined filter plate 302.

[0028] A specific application of this embodiment is: When using the device, first move the device to a designated position, then put the biomass raw material into the housing 101 through the feed port 102, then start the motor 103 to drive the shaft 104 to rotate, the shaft 104 will drive the driving rod 106 and the cutter 108 to rotate during the rotation, the driving rod 106 will drive the pressing roller 107 to rotate, and the pressing roller 107 will rotate with the driving rod 106 as the axis due to the friction between it and the fixed disk 105 during the rotation, so as to crush the biomass raw material falling on the top of the fixed disk 105, and the crushed raw material will enter the fixed disk 105. Inside the through hole of the disk 105, as the pressing roller 107 continues to roll, the raw material entering the through hole will be pressed into a long strip and exposed from the bottom of the fixed disk 105. When the exposed length of the long strip of raw material is long enough, it will be cut and knocked down by the rotating cutter 108. This design can improve the consistency of the generated particles by cutting the raw material by the cutter 108 after it is pressed out a certain distance, thereby preventing the particles from being unable to maintain the uniformity of the length of the particles only by free fracture when being pressed out, and the rotation speed of the cutter 108 is consistent with the rotation speed of the pressing roller 107, so that the particles will be more uniform after being cut, avoiding uneven or incompletely broken particles; In the above process, the raw materials put into the feed inlet 102 will first fall on the top of the material loading plate 202 and accumulate. When the rotating shaft 104 rotates, it will also drive the material loading plate 202 to rotate through the extension rod 201. When a lot of raw materials are accumulated on the top of the material loading plate 202, it is difficult for the material loading plate 202 to rotate together with the raw materials. At this time, the raw materials on the material loading plate 202 will fall into the discharge port 203 and fall out from its bottom. As the material loading plate 202 rotates, the raw materials falling from the discharge port 203 will evenly fall on the top of the filter plate 216, and the raw materials passing through the filter plate 216 will evenly fall on the top of the fixed plate 105. During the rotation of the material loading plate 202, the gear rod 1 204 will drive the gear rod 205 to rotate, and the gear rod 205 will drive the stirring rod 209 to rotate through the gear sleeve rod 206. The stirring rod 209 will rotate against the The material accumulated at the higher part of the top of the material plate 202 is stirred to prevent agglomeration, and the rotation direction of the stirring rod 209 is opposite to that of the material placing plate 202, which can further prevent the material placing plate 202 from driving the material to rotate, and the stirring rod 209 will also drive the thin rod 210 to rotate when rotating, thereby preventing the material contacted by the top of the material placing plate 202 from being blocked and agglomerated, and the provision of a plurality of thin rods 210 can prevent a large amount of material from falling into the material placing port 203 whenever the stirring rod 209 is about to overlap with the material placing port 203 during the stirring process, causing uneven discharge of the material placing port 203, and the above design can discharge the biomass material evenly, prevent the uneven accumulation thickness of the material falling on the top of the fixed plate 105, make the speed of pressing out particles not uniform, and cause the cutting knife 108 to cut different lengths during cutting, and fail to maintain the uniformity of particle length; The material placing plate 202 will also drive the rotating ring 212 to rotate through the connecting plate 211 during the rotation process. The rotating ring 212 will drive the four protrusions 213 to rotate together during the rotation process. When the protrusion 213 rotates to contact the bottom of the ball 214, as the protrusion 213 continues to rotate, the ball 214 will be pushed up. The ball 214 will be pushed up and the filter plate 216 will be driven to move upward through the fixing plate 215. When the ball 214 is separated from the protrusion 213, the filter plate 216 will fall. As the rotating ring 212 continues to rotate, the above process will be repeated, thereby achieving a shaking of the filter plate 216. The filter plate 216 has a spring 218, which can act as a buffer when the filter plate 216 is lifted and compressed, thereby eliminating the small amplitude and irregular vibration of the filter plate 216 and reducing the noise. The staff can collect and recycle the filtered raw materials from the material taking port 219. This design can filter the biomass raw materials falling on the filter plate 216, and prevent the incompletely crushed wood chips in the raw materials from falling on the fixed plate 105 and being pressed into the through holes opened therein to block them. The vibration effect of the filter plate 216 can improve the filtering efficiency and prevent the filter plate 216 from being blocked. The particles produced after being cut by the cutting knife 108 in the above process will fall on the top of the inclined filter plate 302, and the filter plate 216 will also drive the inclined filter plate 302 to shake together through the connecting rod 301 during the up and down shaking process. The particles falling on the top of the inclined filter plate 302 will be discharged from the discharge port 303 along the inclined surface of the inclined filter plate 302 due to the shaking effect of the inclined filter plate 302, and the dust debris falling with the particles will pass through the inclined filter plate 302 and fall to the bottom of the inner wall of the shell 101. The shielding plate 304 can shield the fallen debris to prevent the motor 103 from being affected. The staff can recycle the fallen debris from the return port 305. This design can separate the fallen debris from the particles to prevent the debris from being mixed with the particles and discharged, thereby ensuring that the quality of the biomass particles finally produced is pure without a large amount of debris or impurities.
