Description

Technical Field

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

[0002] Biomass is a broad concept. Simply put, it refers to various organisms produced by photosynthesis using the atmosphere, water, land, etc.

[0003] The patent application with the application number CN202120634382.9 discloses a biomass material processing and grinding device, including a grinding device main body. Inside the grinding device main body, a stirring and crushing chamber, a grinding chamber, and an aggregate chamber are sequentially arranged from top to bottom. A rotating motor is fixedly installed at the top of the grinding device main body, and the output end of the rotating motor is fixedly connected to a rotating shaft. The bottom of the rotating shaft rotates through the stirring and crushing chamber and extends into the grinding chamber.

[0004] When the above device is used, the biomass material is simply ground using a grinding ring. Although the biomass material can be ground in this way, the processing effect is not good, and it is easy to have biomass materials with relatively large particles, which is not conducive to production requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide a biomass material processing device to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A biomass material processing device, including a discharge plate, the outer wall of the discharge plate is fixedly connected with a support plate, the top of the discharge plate is fixedly connected with a conical column, and further includes:

[0007] Grinding mechanism, the grinding mechanism includes a U-shaped plate fixedly connected to the top of the support plate, the bottom of the U-shaped plate is fixedly connected with a first annular plate, the inner wall of the first annular plate is fixedly connected with a fourth annular plate, a second notch is opened at the top of the fourth annular plate, the bottom of the fourth annular plate is fixedly connected with a conical column, the top of the first annular plate is rotationally connected with a rotating assembly through a bearing, the top of the U-shaped plate is fixedly connected with a second annular plate, the top of the second annular plate is fixedly connected with a first housing, the inner wall of the second annular plate is fixedly connected with a third annular plate, a first notch is opened at the top of the third annular plate, a feeding port is opened at the top of the first housing, a second motor is fixedly connected to the top of the first housing, the bottom of the first housing is rotationally connected with an internal assembly through a bearing. When the equipment needs to process biomass materials, start the second motor to provide power for the rotation of the internal assembly. By setting the grinding mechanism, under the up-and-down vibration of the first grinding ring and the vibration of the second grinding ring, the state of the biomass materials inside the equipment becomes more active. Through the grinding between the biomass materials, the particles of the biomass materials become smaller, further improving the processing effect of the equipment.

[0008] The internal assembly includes a central column, the output end of the second motor is fixedly connected to the central column, the bottom of the central column is fixedly connected with a second grinding ring, the bottom of the second grinding ring is rotationally connected with the fourth annular plate through a bearing, and the centers of the second grinding ring and the central column are not on the same axis. In this way, when the internal assembly rotates, the position of the periphery of the second grinding ring will constantly change, playing a role in grinding the biomass materials.

[0009] According to the above technical solution, an extension plate one is fixedly connected to the outer wall of the first annular plate, a first gear is rotationally connected to the top of the extension plate one through a bearing, an extension plate two is fixedly connected to the outer wall of the second annular plate, a first motor is fixedly connected to the top of the extension plate two, and the output end of the first motor is fixedly connected to the first gear. When the equipment needs to process biomass materials, start the first motor to drive the first gear to rotate, and the rotating first gear will provide power for the rotation of the rotating assembly.

[0010] According to the above technical solution, the rotating assembly includes a rotating ring, the bottom of the rotating ring is rotationally connected with the first annular plate through a bearing, the top of the rotating ring is rotationally connected with the second annular plate through a bearing, a second gear is fixedly connected to the outer wall of the rotating ring, and the first gear meshes with the second gear. As the first motor drives the first gear to rotate, the rotating first gear drives the second gear to rotate, and the rotating second gear drives the rotating ring to rotate. By setting the rotating assembly, when the equipment processes biomass materials, the rotation directions of the first grinding ring and the second grinding ring are opposite. At the same time, during the continuous rotation of the second grinding ring, the second grinding ring will continuously vibrate up and down, enhancing the grinding ability of the first grinding ring and improving the processing effect of the equipment.

[0011] According to the above technical solution, a sliding column is fixedly connected to the inner wall of the rotating ring. A sliding ring is movably connected to the outer wall of the sliding column. A first grinding ring is fixedly connected to the inner wall of the sliding ring. Multiple protrusions are provided on the inner wall of the first grinding ring. In this way, when the rotating ring drives the first grinding ring to rotate, it plays a role in grinding and processing biomass materials.

[0012] According to the above technical solution, a spring is sleeved on the outer wall of the sliding column. The top of the spring is fixedly connected to the rotating ring, and the bottom of the spring is fixedly connected to the sliding ring. A cylinder is fixedly connected to the bottom of the sliding ring. The outer wall of the cylinder is movably connected to the rotating ring. A raised point is fixedly connected to the top of the fourth annular plate. When the cylinder rotates with the rotating ring, it will contact the raised point on the top of the fourth annular plate, causing the first grinding ring to move up and down continuously.

[0013] According to the above technical solution, the outer wall of the central column is rotationally connected to the third annular plate through a bearing. A grinding knife is fixedly connected to the outer wall of the central column. When the second motor drives the central column to rotate, it drives the grinding knife to rotate, playing a role in crushing biomass materials. By setting the internal components, before the biomass materials enter between the first grinding ring and the second grinding ring, they will be cut and broken by the grinding knife, reducing the volume of the biomass materials, facilitating the subsequent grinding of the biomass materials by the rotating components and the internal components, and improving the processing effect of the equipment.

[0014] According to the above technical solution, a cavity one is opened inside the central column. A support column is arranged inside the cavity one. The bottom of the support column is fixedly connected to the conical column. The top of the support column is fixedly connected to a circular plate. A cavity two is opened inside the circular plate. A movable column is movably connected to the inner wall of the circular plate. Under the continuous rotation of the central column and the second grinding ring, the movable column continuously knocks on the inside of the second grinding ring, causing the outer surface of the second grinding ring to be in a vibrating state. By setting the internal components, since the central axes of the second grinding ring and the central column are not on the same straight line, when the second grinding ring rotates, the inner wall of the cavity one inside the second grinding ring will continuously squeeze the movable column, causing the movable column on the other side to pop out from the middle and strike the inside of the second grinding ring to generate vibration, enhancing the grinding ability of the second grinding ring and improving the processing effect of the equipment.

[0015] According to the above technical solution, a cavity three is opened on the inner wall of the circular plate. A push rod is fixedly connected to the bottom of the inner wall of the cavity three. A movable block is fixedly connected to the top of the push rod. The outer wall of the movable block is movably connected to the cavity three. When the vibrating state of the second grinding ring is required for this equipment, the movable block is moved downward by the push rod.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The present invention enhances the grinding ability of the second grinding ring and the processing effect of the equipment by setting internal components. Since the central axes of the second grinding ring and the central column are not on the same straight line, when the second grinding ring rotates, the inner wall of the first inner cavity of the second grinding ring will continuously squeeze the movable column, causing the movable column on the other side to pop out from the middle and strike the inside of the second grinding ring to generate vibration.

[0018] 2. The present invention enhances the grinding ability of the first grinding ring and the processing effect of the equipment by setting a rotating component. When the equipment processes biomass materials, the rotation directions of the first grinding ring and the second grinding ring are opposite. At the same time, during the continuous rotation of the second grinding ring, the second grinding ring will continuously vibrate up and down.

[0019] 3. The present invention reduces the volume of biomass materials by cutting and breaking them through grinding knives before the biomass materials enter between the first grinding ring and the second grinding ring, facilitating the subsequent grinding of the biomass materials by the rotating component and the internal component, and improving the processing effect of the equipment.

[0020] 4. The present invention makes the state of the biomass materials inside the equipment more active through the up-and-down shaking of the first grinding ring and the vibration of the second grinding ring. Through the grinding between the biomass materials, the particles of the biomass materials become smaller, further improving the processing effect of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1: Refer to Figures 1 - 6, the present invention provides a technical solution: a biomass material processing device, including a discharge plate 1, a support plate 101 fixedly connected to the outer wall of the discharge plate 1, and a conical column 102 fixedly connected to the top of the discharge plate 1. It further includes:

[0036] A grinding mechanism 2, which includes a U-shaped plate 201 fixedly connected to the top of the support plate 101. A first annular plate 202 is fixedly connected to the bottom of the U-shaped plate 201. A fourth annular plate 2013 is fixedly connected to the inner wall of the first annular plate 202. A second notch 2014 is provided at the top of the fourth annular plate 2013. The bottom of the fourth annular plate 2013 is fixedly connected to the conical column 102. A rotating assembly 21 is rotatably connected to the top of the first annular plate 202 through a bearing. A second annular plate 205 is fixedly connected to the top of the U-shaped plate 201. A first housing 208 is fixedly connected to the top of the second annular plate 205. A third annular plate 2011 is fixedly connected to the inner wall of the second annular plate 205. A first notch 2012 is provided at the top of the third annular plate 2011. A material inlet 2010 is provided at the top of the first housing 208. A second motor 209 is fixedly connected to the top of the first housing 208. An internal assembly 22 is rotatably connected to the bottom of the first housing 208 through a bearing. When the device needs to process biomass materials, start the second motor 209 to provide power for the rotation of the internal assembly 22. An extension plate 203 is fixedly connected to the outer wall of the first annular plate 202. A first gear 204 is rotatably connected to the top of the extension plate 203 through a bearing. An extension plate 206 is fixedly connected to the outer wall of the second annular plate 205. A first motor 207 is fixedly connected to the top of the extension plate 206. The output end of the first motor 207 is fixedly connected to the first gear 204. When the device needs to process biomass materials, start the first motor 207 to drive the first gear 204 to rotate. The rotating first gear 204 will provide power for the rotation of the rotating assembly 21. When it is necessary to process biomass materials, put the biomass materials into the device from the material inlet 2010. The biomass materials will enter the housing. At this time, start the first motor 207 to drive the first gear 204 to rotate. The rotating first gear 204 drives the rotating assembly 21 to rotate. And the start of the second motor 209 will drive the internal assembly 22 to rotate. In this way, after the biomass materials enter the device, they will enter the rotating assembly 21 and the internal assembly 22 from the first notch 2012, and then be discharged from the second notch 2014 and fall into the discharge plate 1.

[0037] The rotating assembly 21 includes a rotating ring 211. The bottom of the rotating ring 211 is rotatably connected to the first annular plate 202 through a bearing, and the top of the rotating ring 211 is rotatably connected to the second annular plate 205 through a bearing. A second gear 212 is fixedly connected to the outer wall of the rotating ring 211. The first gear 204 meshes with the second gear 212. As the first motor 207 drives the first gear 204 to rotate, the rotating first gear 204 drives the second gear 212 to rotate. The rotating second gear 212 drives the rotating ring 211 to rotate. A sliding column 213 is fixedly connected to the inner wall of the rotating ring 211. A sliding ring 214 is movably connected to the outer wall of the sliding column 213. A first grinding ring 217 is fixedly connected to the inner wall of the sliding ring 214. Multiple protrusions are provided on the inner wall of the first grinding ring 217. In this way, when the rotating ring 211 drives the first grinding ring 217 to rotate, it plays a role in grinding and processing biomass materials. As the equipment works, the first motor 207 drives the first gear 204 to rotate. The rotating first gear 204 drives the second gear 212 to rotate, and then drives the rotating ring 211 to rotate through the rotation of the second gear 212. The rotating rotating ring 211 drives the first grinding ring 217 to rotate through the sliding column 213 and the sliding ring 214, and processes the biomass materials inside the equipment.

[0038] A spring 215 is sleeved on the outer wall of the sliding column 213. The top of the spring 215 is fixedly connected to the rotating ring 211, and the bottom of the spring 215 is fixedly connected to the sliding ring 214. A cylinder 216 is fixedly connected to the bottom of the sliding ring 214. The outer wall of the cylinder 216 is movably connected to the rotating ring 211. A raised point 2015 is fixedly connected to the top of the fourth annular plate 2013. As the rotating ring 211 rotates continuously, the cylinder 216 at the bottom of the sliding ring 214 will continuously collide with the raised point 2015. When the cylinder 216 collides with the raised point 2015, it will drive the sliding ring 214 to move upward through the cylinder 216. The upward moving sliding ring 214 will drive the first grinding ring 217 to move upward. When the cylinder 216 moves away from the raised point 2015, the sliding ring 214 will be reset under the push of the spring 215. In this way, the first grinding ring 217 moves up and down continuously, enhancing the processing effect of the equipment.

[0039] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 7 - 9, the internal component 22 includes a central column 221. The output end of the second motor 209 is fixedly connected to the central column 221. A second grinding ring 223 is fixedly connected to the bottom of the central column 221. The bottom of the second grinding ring 223 is rotatably connected to the fourth annular plate 2013 through a bearing. The centers of the second grinding ring 223 and the central column 221 are not on the same axis. In this way, when the internal component 22 rotates, the positions around the second grinding ring 223 will constantly change, playing a role in grinding the biomass material. The outer wall of the central column 221 is rotatably connected to the third annular plate 2011 through a bearing. A grinding knife 222 is fixedly connected to the outer wall of the central column 221. As the equipment operates, the motor drives the central column 221 to rotate. The rotating central column 221 drives the grinding knife 222 to rotate, cutting and crushing the biomass material. At the same time, the rotating central column 221 will drive the second grinding ring 223 to rotate, squeezing and crushing the biomass material.

[0040] A cavity one 224 is opened inside the central column 221. A support column 225 is arranged inside the cavity one 224. The bottom of the support column 225 is fixedly connected to the conical column 102. A round plate 226 is fixedly connected to the top of the support column 225. A cavity two 228 is opened inside the round plate 226. A movable column 227 is movably connected to the inner wall of the round plate 226. Due to the cavity one 224 opened inside the second grinding ring 223, the position of its central axis is consistent with the central axis of the second grinding ring 223. So when the second grinding ring 223 rotates, the side of the inner wall of the cavity one 224 closer to the central axis of the central column 221 will constantly squeeze the movable column 227 to move inward. At this time, the movable column 227 on the other side will rush out of the round plate 226 under the extrusion of air pressure, hitting the second grinding ring 223, thereby achieving a vibration effect.

[0041] A cavity three 229 is opened on the inner wall of the round plate 226. A push rod 2210 is fixedly connected to the bottom of the inner wall of the cavity three 229. A movable block 2211 is fixedly connected to the top of the push rod 2210. The outer wall of the movable block 2211 is movably connected to the cavity three 229. When the equipment needs to release the state of the second grinding ring 223, the push rod 2210 is started to move downward. As the movable block 2211 moves, the gas in the cavity two 228 is inhaled into the cavity three 229, and then the movable column 227 is inhaled into the round plate 226.

[0042] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
