[0001] This utility model relates to the field of food-grade plant activated carbon pulverization technology, and in particular to a pulverization device for the production of food-grade plant activated carbon. Background Technology

[0002] Plant-based activated carbon is a porous carbon material made from plant materials (such as wood, coconut shells, bamboo, and fruit shells) through high-temperature carbonization and activation. It possesses a high specific surface area, abundant pore structure, and strong adsorption properties, and is widely used in environmental protection, medicine, food, and chemical industries. The particle size requirements for plant-based activated carbon vary depending on the application scenario; therefore, different applications have different particle size requirements for activated carbon, necessitating the pulverization of the plant-based activated carbon.

[0003] When existing pulverizing equipment pulverizes activated carbon, the pulverized activated carbon particles tend to adhere to the screen, causing the screen holes to become clogged. If not cleaned in time, this will affect the filtration and screening of the pulverized activated carbon particles, and thus affect the pulverizing efficiency of the activated carbon. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a pulverizing device for the production of food-grade plant activated carbon. This invention solves the technical problem that in the existing pulverizing devices, the pulverized activated carbon particles easily adhere to the screen, causing blockage of the screen holes. If not cleaned in time, this will affect the filtration and screening of the pulverized activated carbon particles, and thus affect the pulverizing efficiency of the activated carbon.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a pulverizer for the production of food-grade plant activated carbon, comprising a pulverizing chamber, a sieve ring inside the pulverizing chamber, a pulverizing blade inside the sieve ring, the pulverizing blade being connected to one end of a first rotating shaft, the other end of the first rotating shaft being connected to a drive device for driving the first rotating shaft to rotate, a turntable being coaxially mounted on the first rotating shaft, the edge of the turntable being connected to one end of a second rotating shaft via a bearing, the other end of the second rotating shaft being connected to a roller brush, the roller brush contacting the outer wall of the sieve ring, and a gear being coaxially mounted on the second rotating shaft, the gear meshing with a gear ring.

[0006] Furthermore, a circular mounting hole is provided on one side of the crushing chamber, and the turntable is mounted inside the circular mounting hole by means of a bearing.

[0007] Furthermore, the screen ring is a cylindrical screen with a hollow interior and open ends, and the side walls of the screen ring are provided with screen holes.

[0008] Furthermore, a feed hopper is installed on one side of the crushing chamber.

[0009] Furthermore, a cover plate is provided at the top feed inlet of the feed hopper.

[0010] Furthermore, limiting blocks are provided on both sides of the cover plate, and limiting plates are provided on both sides of the feed hopper. The limiting plates have strip-shaped limiting grooves along their length, and the limiting blocks on both sides of the cover plate are slidably disposed inside the strip-shaped limiting grooves of the two limiting plates.

[0011] Furthermore, one end of the strip-shaped limiting groove is provided with a fixing groove that cooperates with the limiting block.

[0012] Furthermore, the bottom of the crushing chamber is funnel-shaped and has a discharge port.

[0013] Furthermore, the shredder includes a mounting sleeve coaxially mounted on the first rotating shaft. The outer wall of the mounting sleeve is uniformly provided with several longitudinal blades in a ring around the central axis of the mounting sleeve, and each longitudinal blade is provided with a transverse blade vertically.

[0014] The beneficial effects of this utility model include: This utility model provides a pulverizer for the production of food-grade plant activated carbon. A driving device can drive a first rotating shaft to rotate, which in turn drives a pulverizing blade to pulverize the activated carbon inside the sieve ring. The pulverized activated carbon particles can be filtered out through the sieve ring. Simultaneously, the first rotating shaft can drive a turntable to rotate, which in turn drives a second rotating shaft to revolve around the central axis of the turntable.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] This utility model embodiment provides a pulverizing device for producing food-grade plant activated carbon, such as... Figure 1-5 As shown, it includes a crushing chamber 1, a screen ring 2 inside the crushing chamber 1, a crushing blade 3 inside the screen ring 2, a crushing blade 3 connected to one end of a first rotating shaft 4, and the other end of the first rotating shaft 4 connected to a drive device 5 for driving the first rotating shaft 4 to rotate. A turntable 6 is coaxially mounted on the first rotating shaft 4, and the edge of the turntable 6 is connected to one end of a second rotating shaft 7 through a bearing. The other end of the second rotating shaft 7 is connected to a roller brush 8, and the roller brush 8 contacts the outer wall of the screen ring 2. A gear 9 is coaxially mounted on the second rotating shaft 7, and the gear 9 meshes with a gear ring 10. The first rotating shaft 4 can be driven to rotate by the drive device 5. The first rotating shaft 5 can drive the pulverizing blade 3 to rotate and pulverize the activated carbon inside the screen ring 2. The pulverized activated carbon particles can be filtered out through the screen ring 2. At the same time, the first rotating shaft 4 can drive the turntable 6 to rotate. The turntable 6 can drive the second rotating shaft 7 to revolve around the central axis of the turntable 6, thereby driving the roller brush 8 to revolve around the central axis of the screen ring 2. When the second rotating shaft 7 revolves around the central axis of the turntable 6, the second rotating shaft 7 can drive the gear 9 to roll on the gear ring 10, thereby driving the roller brush 8 to rotate around its central axis. This cleans the screen ring 2 while pulverizing the activated carbon, preventing the screen holes on the screen ring 2 from becoming blocked, which would affect the filtration and screening of activated carbon particles and thus avoid affecting the pulverization efficiency of the activated carbon.

[0023] It should be noted that a circular mounting hole is provided on one side of the crushing chamber 1, and the turntable 6 is mounted inside the circular mounting hole by means of a bearing.

[0024] It should be noted that the sieve ring 2 is a cylindrical sieve with a hollow interior and open ends, and the side wall of the sieve ring 2 is provided with sieve holes for filtering activated carbon particles.

[0025] In this embodiment, a feed hopper 11 is installed on one side of the crushing chamber 1. Activated carbon can be poured into the crushing chamber 1 through the feed hopper 11. The activated carbon poured into the crushing chamber 1 can enter the screen ring 2 through an opening on one side of the screen ring 2. At the same time, a cover plate 12 is provided at the top inlet of the feed hopper 11. When the activated carbon is crushed, the top opening of the feed hopper 11 can be closed by the cover plate 12, which can prevent the activated carbon inside the screen ring 2 from splashing out through the feed hopper 11 during the crushing process, so as to avoid waste of activated carbon and accidents. At the same time, limiting blocks 121 are provided on both sides of the cover plate 12. Both sides are provided with limiting plates 111, and the limiting plates 111 are provided with strip-shaped limiting grooves 1111 along their length direction. The limiting blocks 121 on both sides of the cover plate 12 are respectively slidably disposed inside the strip-shaped limiting grooves 1111 of the two limiting plates 111. The opening at the top of the feed hopper 11 can be opened or closed by sliding the cover plate 12. At the same time, one end of the strip-shaped limiting groove 1111 is provided with a fixing groove 1112 that cooperates with the limiting block 121. When the cover plate 12 covers the opening of the feed hopper 11, the limiting block 121 is inserted into the fixing groove 1112, thereby preventing the cover plate 12 from loosening during the activated carbon crushing process.

[0026] In this embodiment, the bottom of the crushing chamber 1 is funnel-shaped and has a discharge port 13, through which the crushed and filtered activated carbon particles can be discharged.

[0027] It should be noted that the pulverizer 3 includes a mounting sleeve 31 mounted on the first rotating shaft 4. The outer wall of the mounting sleeve 31 is uniformly provided with several longitudinal blades 32 in a ring around the central axis of the mounting sleeve 31. Each longitudinal blade 32 is provided with a transverse blade 33. The blades of the transverse blades 33 are perpendicular to the blades of the corresponding longitudinal blades 32. The pulverization efficiency and pulverization effect of activated carbon can be improved by the cooperation of the longitudinal blades 32 and the transverse blades 32.

[0028] It should be noted that the roller brush 8 includes a brush rod 81 and bristles 82 disposed on the outer wall of the brush rod 81. One end of the brush rod 81 is connected to the second rotating shaft 7. The bristles 82 are made of nylon material. The bristles 82 can clean the screen holes on the screen ring 2 to prevent the screen holes from becoming blocked.

[0029] In this embodiment, the driving device 5 is a motor.

[0030] As for the drive device 5, it only needs to be able to drive the first rotating shaft 4 to rotate. Therefore, it is not limited to using a motor. For example, in some other embodiments, the drive device 5 uses a hydraulic motor or a pneumatic motor or other drive components that can drive the first rotating shaft 4 to rotate.

[0031] In terms of specific principle, when pulverizing activated carbon, the activated carbon is poured into the pulverizing chamber 1 through the feed hopper 11. The activated carbon poured into the pulverizing chamber 1 enters the sieve ring 2 through an opening on one side. The drive device 5 drives the first rotating shaft 4 to rotate, which in turn drives the pulverizing blades 3 to pulverize the activated carbon inside the sieve ring 2. The pulverized activated carbon particles are filtered out through the sieve ring 2 and enter the pulverizing chamber 1. The activated carbon particles inside the pulverizing chamber 1 are discharged from the pulverizing chamber 1 through the discharge port 12. At the same time, the first rotating shaft 4... The rotating disk 6 can drive the second rotating shaft 7 to revolve around the central axis of the rotating disk 6, thereby driving the roller brush 8 to revolve around the central axis of the screen ring 2. When the second rotating shaft 7 revolves around the central axis of the rotating disk 6, the second rotating shaft 7 can drive the gear 9 to roll on the gear ring 10, thereby driving the roller brush 8 to rotate around its central axis, so as to clean the screen ring 2 while pulverizing the activated carbon, and avoid the screen holes on the screen ring 2 from becoming blocked, which would affect the filtration and screening of activated carbon particles.
