Description

A water hemp fiber powder processing device Technical Field

[0001] This invention belongs to the field of material crushing technology and relates to a processing device for hemp fiber powder. Background Technology

[0002] Crushing technology has been widely applied in various sectors of the national economy, effectively promoting social progress and improving people's quality of life. The selection of crushing equipment varies depending on the raw materials and application scenarios. For example, different processing equipment is required for materials with high oil content, high water content, high toughness and strength, brittleness, and high temperature sensitivity, as well as for the same material requiring different crushing effects.

[0003] The roots and bark of the water hemp bark tree, after being dried and crushed, become water hemp bark powder, also known as black hemp powder or cotton stone.

[0004] The powder obtained by drying and grinding the roots and bark of the *Hedychium coronarium* tree is commonly known as *Hedychium coronarium powder*, *Hedychium sibiricum* powder, or cotton stone. As a natural binder, *Hedychium coronarium powder* possesses advantages such as being pollution-free, of high quality, having strong adhesive properties, stable quality, and naturally odorless. In recent years, its application scope has been expanding, and its market prospects are promising. It not only sells well domestically but is also exported worldwide. There are hundreds of *Hedychium coronarium powder* manufacturers in my country; however, the grinding process accounts for approximately 20% to 40% of the cost from raw materials to finished product.

[0005] Currently, the main raw materials for processing Hemp fiber powder are the roots and stem bark of the Hemp fiber tree, which possess good toughness and strength. Hemp fiber powder becomes sticky upon contact with water, resembling a gel-like liquid that can be drawn into threads, exhibiting strong adhesion. During processing in a pulverizer, the dry powder easily adheres to equipment parts. If not removed promptly, the increasing amount of adsorption will affect the processing effect; furthermore, when it comes into contact with water, it becomes sticky and adheres to the equipment parts, further exacerbating the processing effect. In addition, temperature also affects the performance of Hemp fiber powder. When the temperature exceeds 80℃, the powder is prone to overburning, turning black and rendering it unusable as a binder. Due to the aforementioned characteristics of Hemp fiber powder and its raw materials, the current methods for pulverizing the roots and stem bark of the Hemp fiber tree to obtain Hemp fiber powder are difficult, resulting in poor pulverization effects and low product yield.

[0006] Therefore, it is necessary to provide a water hemp bark powder processing device that addresses the characteristics of water hemp bark raw materials and solves the problems that easily occur during the crushing process. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water hemp bark powder processing device that can effectively crush the roots and stems of water hemp trees with high strength and toughness. During the crushing process, the device removes the powder adhering to the key components in a timely manner, reduces or eliminates the amount of powder adhering to the key components, and reduces the impact of the adhering powder and its stickiness when it comes into contact with water on the processing. At the same time, the device is cooled during the crushing process to avoid the powder from over-burning.

[0008] To achieve the above objectives, the technical solution adopted by this invention is as follows:

[0010] The outer shell assembly 1 and the upper cover assembly 5 are connected by screws to form a closed crushing chamber. The support assembly 2, the gravity rotating block assembly 3, and the crushing hammer assembly 4 are located in the crushing chamber. The gravity rotating block assembly 3 includes a first rotating part and a second rotating part.

The revolution shaft 13 is rotatably connected to the outer shell assembly 1 through a rolling bearing. A pulley 12 is installed at the bottom end of the revolution shaft 13, and the pulley 12 is coaxial with the revolution shaft 13. The revolution shaft 13 drives the support assembly 2 to rotate, which in turn drives the gravity rotating block assembly 3 to rotate around the axis of the revolution shaft. Under centrifugal force, the crushing hammer assembly 4 moves further outward around the rotation axis of the first rotating part, impacts the inner side wall of the crushing chamber, and rebounds, continuously repeating the above actions.

[0011] Preferably, there are at least 5 sets of crushing hammer assemblies 4, which are evenly arranged around the revolution axis 6, and the number of gravity rotating block assemblies 3 matches the number of crushing hammer assemblies 4.

[0012] Preferably, the outer casing assembly 1 includes a housing 11 and a grinding ring 16. The housing 11 is connected to the upper cover assembly 5 by screws, and the grinding ring 16 is fixedly installed on the inner side wall of the housing 11 as the side wall of the crushing chamber.

[0013] Preferably, the outer shell assembly 1 further includes a cooling water ring 14, which is fixedly sleeved on the outer wall of the shell 11. The cooling water ring 14 is provided with a first water inlet 17 and a first water outlet 18.

[0014] Preferably, the support assembly 2 includes a base plate 21, a sleeve support 22, and an upper partition plate 23. The base plate 21 is fixedly connected to the upper partition plate 23 via the sleeve support 22. The upper partition plate 23 is fixedly connected to the revolution shaft 13 via the top ring 15 of the sleeve support. Circular grooves 24 are formed on the top surface of the base plate 21 and the bottom surface of the upper partition plate 23. An elongated oval 26 is formed on the upper partition plate 23. The first rotating part of the gravity rotating block assembly 3 is located in the circular groove 24 and is fixedly connected to the base plate 21 and the upper partition plate 23. The second rotating part of the gravity rotating block assembly 3 passes through the elongated oval 26 and is rotatably connected to the crusher assembly 4.

[0015] Preferably, a plurality of ears 25 are uniformly fixedly provided on the edge of the upper partition 23 along the circumferential direction.

[0016] Preferably, the gravity rotating block assembly 3 includes a short shaft 31, a gravity rotating block 32, a long shaft 33, and a sliding bearing base 34. The short shaft 31 is fixedly connected to the gravity rotating block 32, and the short shaft 31 is rotatably connected to the sliding bearing base 34 via a large sliding bearing 35 to form a first rotating part. The gravity rotating block 32 and the long shaft 33 are fixedly connected to form a second rotating part. The sliding bearing base 34 is fixedly mounted on the support assembly 2. The long shaft 33 passes through the support assembly 2 and is rotatably connected to the crusher assembly 4. A short shaft base 37 is also installed in the large sliding bearing 35 at the bottom of the short shaft 31. A ball bearing 36 is rolled in the short shaft base. A short shaft top seat 38 is also installed in the large sliding bearing at the top of the short shaft 31.

[0017] Preferably, the short shaft top seat 38 is provided with an oil injection hole, and the upper partition plate 23 is provided with an oil filling through hole. The short shaft 31 and the long shaft 33 are provided with closed and connected lubrication oil passages in both the radial and axial directions, corresponding to the oil groove of the large sliding bearing 35. The closed and connected lubrication oil passages are achieved by drilling axial holes in the shaft and radial holes in the bearing locations, with the axial holes and radial holes connected. The large sliding bearing 35 also has V-grooves inside that correspond to the radial holes. By periodically adding oil through the oil filling through hole and the oil injection hole, the components are lubricated on the one hand, and on the other hand, a certain cooling effect is achieved. Without lubricating oil, the temperature of the components will rise relatively quickly during operation, which can easily lead to an increase in material temperature and overheating.

[0018] Preferably, the crushing hammer assembly 4 includes a lower end cover 41, a hammer body 42, an upper end cover 43, and an oil reservoir 44. The lower end cover 41 is fixedly connected to the bottom end of the hammer body 42 by bolts, and the upper end cover 43 is fixedly connected to the top end of the hammer body 42 by screws. The oil reservoir 44 is fixedly disposed in the middle of the top surface of the upper end cover 43, and an oil filling hole is provided on the top of the oil reservoir 44.

The side wall of the double-layer hollow shell 51 is provided with a feed inlet 52. The top surface of the double-layer hollow shell 51 is fixedly installed with a discharge pipe 53. The outer shell assembly 1 is fixedly connected to the ground through a frame.

[0020] Preferably, an observation hole 19 is provided on the housing 11.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention utilizes the centrifugal force generated by the rotation of the revolution shaft to cause the crushing hammer assembly to move centrifugally, thereby impacting the hemp fiber raw material located between the crushing hammer assembly and the outer shell assembly, crushing the hemp fiber raw material. At the moment of impact, the crushing hammer assembly is subjected to the reaction force generated by the collision and compression with the hemp fiber material, causing it to rebound centrifugally. Subsequently, it is subjected to centrifugal force again to move centrifugally, thus repeatedly impacting the hemp fiber raw material, continuously crushing the hemp fiber raw material to obtain hemp fiber powder. At the same time, during the impact process, the contact area between the crushing hammer assembly and the side wall of the crushing chamber is small, which can generate greater pressure under the same pressure conditions, so that the crushing hammer assembly can crush the high-strength hemp fiber raw material.

[0023] 2. In this invention, at the moment the hammer body of the crushing hammer assembly strikes the hemp fiber material, due to the relative movement between the hammer body and the side wall of the crushing chamber, the hammer body also produces a certain kneading effect on the hemp fiber material. This not only helps to crush the tough hemp fiber material, but also, to a certain extent, disperses the clumps of hemp fiber powder remaining on the hammer body or grinding ring during the hammering, resulting in a more uniform particle size of the final product.

[0024] 3. In this invention, at the moment the hammer strikes the hemp fiber raw material, the hammer will also be subject to friction and rotate. The rotation of the hammer can cause some of the hemp fiber powder attached to the hammer to be thrown off the hammer by centrifugal force, which has a certain effect on removing the hemp fiber powder attached to the hammer.

[0025] 4. By setting up a cooling water ring and a double-layer hollow shell, the present invention can reduce the temperature of the grinding chamber through circulating water cooling, thereby avoiding overheating of the water-hemp fiber powder.

[0026] 5. By incorporating an ear-like structure, this invention scrapes off the hemp fiber powder adsorbed on the grinding ring, reducing the amount of hemp fiber powder adsorbed on the grinding ring and thus minimizing the impact of excessive hemp fiber powder adsorbed on the grinding ring on the pulverizing process.

[0027] 6. By providing an oil injection hole, this invention allows for the addition of lubricating oil, thereby reducing friction between moving parts, lowering the probability of component damage, and extending the device's service life. It also helps lower the temperature of moving parts, thus preventing overheating of the hemp fiber powder. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to specific embodiments.

[0037] As shown in Figures 1-6, the water hemp skin powder processing device includes an outer shell assembly 1, a support assembly 2, a gravity rotating block assembly 3, a crushing hammer assembly 4, an upper cover assembly 5, a pulley 12, a revolution shaft 13, and a sleeve support top ring 15.

[0038] The outer shell assembly 1 and the upper cover assembly 5 are connected by screws to form a closed crushing chamber. The support assembly 2, the gravity rotating block assembly 3, and the crushing hammer assembly 4 are located in the crushing chamber. The gravity rotating block assembly 3 includes a first rotating part and a second rotating part. The rotation axis of the first rotating part and the rotation axis of the second rotating part are parallel to each other and offset. The second rotating part is rotatably connected to the crushing hammer assembly 4. The first rotating part is rotatably connected to the support assembly 2. The support assembly 2 is fixedly connected to the revolution shaft 13 through the sleeve support top ring 15. The revolution shaft 13 is rotatably connected to the outer shell assembly 1 through a rolling bearing. A pulley 12 is installed at the bottom of the revolution shaft 13 and the pulley 12 is coaxial with the revolution shaft 13.

[0039] The revolution shaft 13 drives the support assembly 2 to rotate, which in turn drives the gravity rotating block assembly 3 to rotate around the axis of the revolution shaft. Under centrifugal force, the crushing hammer assembly 4 deflects further outward around the rotation axis of the first rotating part, bounces back after hitting the inner side wall of the crushing chamber, and repeats the above action continuously.

[0040] The number of crushing hammer assemblies 4 is at least 5, and they are evenly arranged around the revolution axis 6. The number of gravity rotating block assemblies 3 matches the number of crushing hammer assemblies 4.

[0041] The pulley 12 is connected to the power source via a belt. When the power source is turned on, the pulley 12 rotates under the drive of the belt, thereby driving the revolution shaft 13 to rotate. The rotation of the revolution shaft 13 drives the support assembly 2 to rotate, and also causes the gravity rotating block assembly 3 and the crushing hammer assembly 4 to perform circular motion around the revolution shaft 13 as the central axis. During the circular motion of the gravity rotating block assembly 3 and the crushing hammer assembly 4, they experience centrifugal force, resulting in centrifugal motion. Since the first rotating part is fixedly connected to the support assembly 2, it does not experience centrifugal motion but instead rotates. The second rotating part experiences centrifugal motion, its trajectory being a circle centered on the first rotating part. Because the second rotating part is rotatably connected to the crushing hammer assembly 4, the crushing hammer assembly 4 also experiences centrifugal motion from the second rotating part. With the same trajectory, during the centrifugal motion of the crushing hammer assembly 4, it hammers the hemp fiber material located between the crushing hammer assembly 4 and the side wall of the crushing chamber, crushing the hemp fiber material. At the moment the crushing hammer assembly 4 hammers the hemp fiber material, due to the reaction force generated by the compression and collision of the hemp fiber material, and due to inertia, it will rebound centripetally. Therefore, neither the second rotating part nor the crushing hammer assembly 4 will perform a complete circular motion. During the centripetal rebound of the crushing hammer assembly 4, it will be continuously subjected to centrifugal force, causing it to rebound a certain distance before undergoing centrifugal motion again to hammer the hemp fiber material. Thus, the crushing hammer assembly repeatedly centrifuges and rebounds, repeatedly hammering the hemp fiber material in the crushing chamber until it is pulverized. At the moment the crushing hammer assembly 4 strikes the hemp fiber raw material, there is relative motion between the crushing hammer assembly 4, which is rotating around the revolution axis 13, and the stationary side wall of the crushing chamber. As a result, at the moment the crushing hammer assembly 4 strikes the hemp fiber raw material, it will produce a certain kneading effect on the hemp fiber raw material, which helps to break the tough hemp fiber raw material, and at the same time can break up the clumps of hemp fiber powder.

[0042] The outer casing assembly 1 includes a housing 11 and a grinding ring 16. The housing 11 is connected to the upper cover assembly 5 by screws, and the grinding ring 16 is fixedly installed on the inner side wall of the housing 11 as the side wall of the crushing chamber.

[0043] The grinding ring 16 is made of high-strength wear-resistant material, which can better withstand the pressure and other effects generated on the grinding ring 16 when the crushing hammer assembly 4 hammers the water-hemp raw material.

[0044] The support assembly 2 includes a base plate 21, a sleeve support 22, and an upper partition plate 23. The base plate 21 is fixedly connected to the upper partition plate 23 through the sleeve support 22. The upper partition plate 23 is fixedly connected to the revolution shaft 13 through the top ring 15 of the sleeve support. Circular grooves 24 are formed on the top surface of the base plate 21 and the bottom surface of the upper partition plate 23. An elongated oval 26 is formed on the upper partition plate 23. The first rotating part of the gravity rotating block assembly 3 is located in the circular groove 24 and is fixedly connected to the base plate 21 and the upper partition plate 23. The second rotating part of the gravity rotating block assembly 3 passes through the elongated oval 26 and is rotatably connected to the crusher assembly 4.

[0045] The base plate 21 and the upper partition plate 23 sandwich the gravity rotating block assembly 3 in the middle, providing support and fixation for the gravity rotating block assembly 3. The revolution shaft 13 passes through the inside of the sleeve support 22 and is fixedly connected to the upper partition plate 23. The sleeve support 22 provides a certain degree of protection for the revolution shaft 13. When the second rotating part passes through the long waist circle 26 and is rotatably connected to the crushing hammer assembly 4, when the crushing hammer assembly 4 is subjected to a reaction force and rebounds centripetally, it will drive the second rotating part to also move centripetally. During the centripetal movement, the second rotating part moves centripetally a certain distance and then stops due to the restriction effect of the long waist circle 26, thereby causing the crushing hammer assembly rotatably connected to it to also stop moving centripetally. Afterwards, under the action of centrifugal force, the second rotating part and the crushing hammer assembly 4 will undergo centrifugal motion.

[0046] Multiple ears 25 are evenly fixedly arranged along the circumferential direction on the edge of the upper partition 23.

[0047] During the rotation of the revolution shaft 13, the upper partition 23 is driven to rotate around the revolution shaft 13, thereby causing the ear 25 at the edge of the upper partition 23 to rotate around the revolution shaft 13, scraping the side wall of the crushing chamber to remove the water hemp skin powder adsorbed on the side wall of the crushing chamber.

[0048] The gravity rotation block assembly 3 includes a short shaft 31, a gravity rotation block 32, a long shaft 33, and a sliding bearing base 34. The short shaft 31 is fixedly connected to the gravity rotation block 32, and the short shaft 31 is rotatably connected to the sliding bearing base 34 through a large sliding bearing 35 to form a first rotating part. The gravity rotation block 32 and the long shaft 33 are fixedly connected to form a second rotating part. The sliding bearing base 34 is fixedly mounted on the support assembly 2. The long shaft 33 passes through the support assembly 2 and is rotatably connected to the crusher assembly 4. A short shaft base 37 is also installed in the large sliding bearing 35 at the bottom of the short shaft 31. Ball bearings 36 are rolled in the short shaft base. A short shaft top seat 38 is also installed in the large sliding bearing at the top of the short shaft 31.

[0049] When the gravity rotating block 32 and the crusher assembly 4 are subjected to centrifugal force and generate centrifugal motion, the short axis 31 rotates, and the long axis 33 moves in a circle with the short axis 31 as the center. Since the long axis 33 is rotatably connected to the crusher assembly 4, the motion trajectory of the long axis 33 is the same as that of the crusher assembly 4, and it will not perform a complete circular motion.

[0050] The crushing hammer assembly 4 includes a lower end cover 41, a hammer body 42, an upper end cover 43, and an oil reservoir 44. The lower end cover 41 is fixedly connected to the bottom end of the hammer body 42 by bolts, and the upper end cover 43 is fixedly connected to the top end of the hammer body 42 by screws. The oil reservoir 44 is fixedly disposed in the middle of the top surface of the upper end cover 43, and an oil filling hole is provided on the top of the oil reservoir 44. The hammer body 42 is rotatably connected to the second rotating part of the gravity rotating block assembly 3 through rolling bearings 46 and sliding small bearings 47. The sliding small bearings 47 are located between the two rolling bearings 46, and the hammer body 42 is provided with helical teeth 45.

[0051] The hammer body 42 is rotatably connected to the gravity rotating block assembly 3 via bearings. When the hammer body 42 hammers the hemp fiber raw material, in addition to the reaction force, it is also subject to friction, causing the hammer body 42 to rotate. The rotation of the hammer body 42 generates centrifugal force on the hemp fiber powder adsorbed on its surface, thereby throwing some of the adsorbed hemp fiber powder off the hammer body, achieving a certain powder removal effect. By setting helical teeth 45 on the hammer body 42, the contact area between the hammer body 42 and the hemp fiber raw material is further reduced, which further increases the pressure and is more conducive to crushing the hemp fiber raw material. At the same time, the helical teeth 45 also have a certain cutting effect on the hemp fiber raw material, further improving the crushing effect. Lubricating oil is added through the oil injection hole, which not only lubricates the parts, but also has a certain cooling effect on the parts, thereby reducing the temperature of the parts and helping to reduce the temperature inside the crushing chamber, preventing the hemp fiber powder from overheating. By opening a small-diameter hole at the bottom of the oil reservoir 44, the lubricating oil with a certain viscosity can be slowly discharged from the oil reservoir 44 to achieve a continuous lubrication effect.

[0052] The outer shell assembly 1 also includes a cooling water ring 14, which is fixedly sleeved on the outer wall of the shell 11. The cooling water ring 14 is provided with a first water inlet 17 and a first water outlet 18.

[0053] The upper cover assembly includes a double-layer hollow shell 51, which is fixedly connected to the outer shell assembly 1 by screws. A cooling chamber is constructed inside the side wall of the double-layer hollow shell 51. A second water inlet 54 and a second water outlet 55 communicating with the cooling chamber are provided on the outer side wall of the double-layer hollow shell 51. A feed inlet 52 is provided on the side wall of the double-layer hollow shell 51. A discharge pipe 53 is fixedly installed on the top surface of the double-layer hollow shell 51. The outer shell assembly 1 is fixedly connected to the ground through a frame.

[0054] Because the hemp fiber powder will overheat and turn black when the temperature exceeds 80℃, making it unusable as a binder, cooling water is continuously supplied to the first water inlet 17 during the pulverizing process. The cooling water flows within a cooling water ring and exits through the first water outlet 18, cooling the pulverizing chamber to prevent overheating of the hemp fiber powder. During the pulverizing process, cooling water is also continuously supplied to the second water inlet 54. This cooling water flows within the cooling chamber and exits through the second water outlet 55, also cooling the pulverizing chamber.

[0055] After adding the raw material of hemp fiber through the feed port 52, the feed port 52 is covered. The crushing chamber is pressurized by using an air compressor, so that the hemp fiber powder is discharged from the discharge pipe 53. The discharge pipe 53 can be connected to a vibrating screen. The discharged hemp fiber powder directly enters the vibrating screen for screening, and qualified hemp fiber powder is collected.

[0056] An observation hole 19 is provided on the housing 11. This allows staff to observe the operation of the gravity-driven rotating block assembly 3 through the observation hole 19 to determine whether the device is operating normally.

[0057] The working process of this invention is as follows: When crushing is required, the feeder adds the hemp fiber raw material into the crushing chamber through the feed pipe. Then, the first and second water inlets are connected to a cold water source, and the cold water source is turned on to supply cold water. The power source is turned on, and the power source drives the pulley to rotate via a belt, starting the crushing of the hemp fiber raw material. During the crushing process, the operator can observe the operation of the gravity rotating block assembly through the observation hole to confirm that the device is in normal working condition. The crushed hemp fiber powder enters the vibrating screen from the discharge pipe. After the crushing of the hemp fiber raw material is completed and the operator confirms through the observation hole that all hammers are in the closest position to the revolution axis, the power source and cold water source are turned off, the collection container is removed, and the water in the cooling water ring and the cavity of the double-layer hollow shell is extracted through the first and second water outlets, thus completing the entire crushing process. If occasionally all hammers fail to return to the position closest to the revolution axis, the hammers can be manually moved to the position closest to the revolution axis by contacting the bolt connection between the upper cover assembly and the outer shell assembly.

[0058] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
