[0002] Coal-based activated carbon is an artificial carbon material obtained by processing carbon-containing substances. It has a highly developed pore structure and a huge specific surface area. Therefore, it is widely used in many environmental protection fields such as water treatment and gas purification. With the strengthening of environmental protection policies and the continuous expansion of activated carbon application fields, the market demand for coal-based activated carbon continues to grow. In the production and processing of coal-based activated carbon, grinding equipment plays an important role. The production of coal-based activated carbon specifically includes several aspects such as coal preparation, coal molding, and coal carbonization. Among them, the raw coal crushing activated carbon production process is a process of crushing the raw coal, and then carbonizing, activating, crushing, and packaging production. This process requires efficient grinding equipment to achieve the crushing of the raw coal for the subsequent carbonization and activation steps.

[0003] In the published Chinese patent application, the publication number is CN115121356B, and the patent name is: A screening device for producing wood activated carbon with a crushing function. The prior art is provided with a first crushing roller and a second motor, and the second motor drives the first crushing roller to rotate at the lower end opening of the conveying cylinder, so as to facilitate the crushing of the wood activated carbon, facilitate the preliminary crushing, and facilitate the screening. A second crushing roller and a moving gear are provided, and the second crushing roller is connected to the inside of the crushing box through the meshing of the moving gear and the moving tooth groove to roll, so as to facilitate the full crushing of the wood activated carbon and facilitate the later screening. At the same time, the crushing box swings inside the dustproof box, which facilitates the swing screening of the activated carbon and avoids clogging the lower end sieve hole of the crushing box. Although the prior art can realize the crushing and screening of activated carbon, the prior art has certain limitations in its specific implementation. In the specific implementation process of this prior art, the third motor and the second crushing roller are installed on the crushing box, and the third motor is used to drive the second crushing roller to reciprocate on the crushing box, thereby crushing the activated carbon in the crushing box; because the crushing box also takes into account the screening function, the crushing box partially rotates around the rotating shaft during screening, so that the third motor is in a swinging state when working. The third motor is unstable in this state, and the third motor is located inside the dustproof box. The activated carbon dust can easily enter the third motor, affecting the normal operation of the third motor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0018] See also Figures 1 to 7 The present invention provides a technical solution: a grinding device for the production and processing of coal-based activated carbon, which is used for grinding and screening coal-based activated carbon, including a box body 1, a conveying cylinder 2, a motor 4, and a collecting box 48. The conveying cylinder 2 is fixedly installed above the box body 1, and the bottom of the conveying cylinder 2 is connected to the top of the box body 1. The motor 4 is installed on the conveying cylinder 2, and a feed port 3 is opened on the top of the conveying cylinder 2.

[0019] The feed port 3 is used to transport the coal-based activated carbon material into the conveying cylinder 2 .

[0020] A conveying component and a first grinding component are respectively arranged on the conveying cylinder 2, a second grinding component is arranged on the inner upper part of the box body 1, a screening component is arranged on the inner lower part of the box body 1, and the motor 4 is respectively connected to the conveying component, the first grinding component, the second grinding component and the screening component.

[0021] The conveying part is used to convey the coal-based activated carbon material in the conveying cylinder 2. At the same time, the coal-based activated carbon material is individually agglomerated during the conveying process, making the material looser. The first grinding part and the second grinding part are both used for breaking and grinding the coal-based activated carbon material. The screening part is used to screen the broken and ground material.

[0022] The second grinding part includes a screen box 25 and a crushing roller 31. An arc-shaped chute 49 is provided on the inner wall of the box body 1. The screen box 25 is slidably arranged on the inner wall of the box body 1 through the arc-shaped chute 49. The motor 4 is connected to the screen box 25 by transmission. The motor 4 drives the screen box 25 to slide back and forth along the arc-shaped chute 49 inside the box body 1. A screen is fixedly installed on the inner bottom of the screen box 25, and the crushing roller 31 is rotatably arranged on the screen. The screen box 25 is connected to the crushing roller 31 by transmission. When the screen box 25 slides back and forth along the arc-shaped chute 49 inside the box body 1, the crushing roller 31 drives the rotation. The crushing roller 31 rotates, crushes and grinds the coal-based activated carbon material in the screen box 25.

[0023] The screen box 25 is driven by the motor 4 to slide back and forth inside the box body 1. The screen box 25 drives the crushing roller 31 to rotate during the reciprocating sliding displacement process. The crushing roller 31 rotates and rolls the coal-based activated carbon material inside the screen box 25, and performs secondary crushing and grinding on the coal-based activated carbon material. At the same time, the screen box 25 performs a first screening of the activated carbon material inside it. If the activated carbon material cannot be screened off, it will continue to be crushed and ground by the crushing roller 31, thereby achieving the purpose of fully and effectively grinding and screening the coal-based activated carbon material. The two outer side walls of the screen box 25 are fixedly connected to the limit block 26, which is located in the arc chute 49, and the limit block 26 is slidably connected to the box body 1 through the arc chute 49.

[0024] The conveying component conveys the coal-based activated carbon to the first grinding component, and the first grinding component crushes and grinds the coal-based activated carbon material once. After being ground by the first grinding component, the coal-based activated carbon falls into the screen box 25. The crushing roller 31 in the second grinding component grinds the coal-based activated carbon in the screen box 25 for a second time. The screen box 25 performs a preliminary screening of the crushed coal-based activated carbon material when it slides back and forth inside the box body 1. The coal-based activated carbon powder after the preliminary screening falls onto the screening component, and the screening component performs a secondary screening on the coal-based activated carbon powder.

[0025] Specifically, the conveying component includes a spiral blade 5, a rotating shaft, and a first gear 7. Both ends of the rotating shaft pass through the conveying cylinder 2. The spiral blade 5 is mounted on the outer wall of the rotating shaft and the two are fixedly connected. The motor 4 is in transmission connection with one end of the rotating shaft. The first gear 7 is mounted on the other end of the rotating shaft and the two are fixedly connected. The motor 4 drives the spiral blade 5 to rotate, and the spiral blade 5 pushes the coal-based activated carbon to move. The coal-based activated carbon is crushed after being pushed during movement (the material is initially broken to avoid material agglomeration).

[0026] The motor 4 is fixedly mounted on the conveying cylinder 2. After the motor 4 is started, the output shaft of the motor 4 drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade 5 to rotate. The spiral blade 5 rotates to push the coal-based activated carbon material in the conveying cylinder 2 to move. When pushing the material, the spiral blade 5 can loosen the material initially to prevent the material from agglomerating. The spiral blade 5 transports the material from the end where the feed port 3 is located inside the conveying cylinder 2 to the other end where the first grinding component is located.

[0027] Further specifically, the first grinding component includes a first crushing roller 8, a second gear 9, a second crushing roller 10, and a third gear 11. The first crushing roller 8 and the second crushing roller 10 are rotatably arranged in parallel on the bottom inner wall of the conveying cylinder 2. The second gear 9 is sleeved on one end of the first crushing roller 8 and the two are fixedly connected. The third gear 11 is sleeved on one end of the second crushing roller 10 and the two are fixedly connected. The second gear 9 is meshed with the third gear 11, and the first gear 7 is meshed with the second gear 9.

[0028] The first grinding component is used to crush and grind the material conveyed by the conveying component. The motor 4 drives the first gear 7 to rotate through the rotating shaft, the first gear 7 drives the second gear 9 meshing with it to rotate, the second gear 9 drives the first crushing roller 8 and the third gear 11 to rotate respectively, the third gear 11 drives the second crushing roller 10 to rotate, the first crushing roller 8 and the second crushing roller 10 rotate towards each other at the same time, and the material is crushed and ground, that is, the material is crushed and ground once.

[0029] Specifically, the second grinding component also includes a second gear ring 34, a rotating rod 27, and a receiving rod 29. The lower end of the receiving rod 29 is rotatably connected to the screen. The outer wall of the receiving rod 29 is fixedly connected to a shaft rod. The crushing roller 31 is mounted on the shaft rod and the two are rotatably connected. The upper end of the receiving rod 29 is mounted with a fourth bevel gear 30 and the two are fixedly connected. The rotating rod 27 penetrates a side wall of the screen box 25 and the two are rotatably connected. One end of the rotating rod 27 is fixedly connected to the third bevel gear 28, and the third bevel gear 28 is meshed with the fourth bevel gear 30. The other end of the rotating rod 27 is fixedly connected to the sixth gear 35. The second gear ring 34 is fixedly installed on the inner wall of the box body 1, and the second gear ring 34 and the arc-shaped slide groove 49 are the same center. The sixth gear 35 is meshed with the second gear ring 34.

[0030] Among them, the material crushed and ground by the first grinding component falls into the screen box 25. The motor 4 drives the screen box 25 to slide and displace reciprocatingly along the arc chute 49 inside the box body 1, that is, the screen box 25 shakes back and forth inside the box body 1. When the screen box 25 moves inside the box body 1, the screen box 25 drives the rotating rod 27 to move back and forth along the direction of the arc chute 49. Since the sixth gear 35 is meshed with the second gear ring 34, the sixth gear 35 moves and rotates on the second gear ring 34, the sixth gear 35 drives the rotating rod 27 to rotate, the rotating rod 27 drives the third bevel gear 28 to rotate, the third bevel gear 28 drives the fourth bevel gear 30 meshed with it to rotate, the fourth bevel gear 30 drives the receiving rod 29 to rotate, that is, the receiving rod 29 rotates on the screen, the shaft rod rotates with the receiving rod 29 as the axis, and the shaft rod drives the crushing roller 31 to rotate, that is, the crushing roller 31 rotates with the receiving rod 29 as the axis, and the rotation process of the crushing roller 31 is revolution. The crushing roller 31 crushes the grinding material during the revolution.

[0031] More specifically, the second grinding component also includes a first gear ring 33 and a fifth gear 32. The fifth gear 32 is fixedly mounted on the end of the crushing roller 31 away from the receiving rod 29. The first gear ring 33 is fixedly mounted on the inner wall of the screen box 25. The fifth gear 32 is meshed with the first gear ring 33.

[0032] Among them, since the fifth gear 32 is meshed with the first gear ring 33, the fifth gear 32 rolls along the first gear ring 33 during the revolution of the crushing roller 31, and the fifth gear 32 rotates and drives the crushing roller 31 to rotate. The crushing roller 31 rotates around the shaft as the axis. The rotational motion process of the crushing roller 31 is self-rotation. The crushing roller 31 crushes, grinds and grinds the material on the screen during the self-rotation process.

[0033] The second grinding component also includes a circular plate 22, a clamping column 23, and a swing plate 24. One end of the swing plate 24 is fixedly connected to a first pin shaft, which penetrates a side wall of the box body 1 and the two are rotatably connected. The first pin shaft is located at the center of the arc-shaped slide groove 49. The other end of the swing plate 24 is fixedly connected to the screen box 25. The screen box 25 rotates with the first pin shaft as the center of the circle. The screen box 25 partially rotates and swings around the first pin shaft through the swing plate 24. The swing plate 24 is provided with a slide groove.

[0034] The second pin is fixedly connected at the center of one side wall of the circular plate 22, and the second pin penetrates through one side wall of the box body 1 and the two are rotatably connected. The other side wall of the circular plate 22 is fixedly connected to the clamping column 23 near the edge of the circumference. The clamping column 23 is inserted into the slide groove of the swing plate 24, and the clamping column 23 is slidably connected to the swing plate 24 through the slide groove. The motor 4 is transmission-connected with the second pin, and the motor 4 drives the second pin to rotate, and the second pin drives the circular plate 22 to rotate, and the circular plate 22 drives the clamping column 23 to rotate. During the rotation of the clamping column 23, the lower end of the swing plate 24 is pushed to swing, that is, the swing plate 24 partially rotates (sways) around the first pin, and the swing plate 24 drives the screen box 25 to swing, thereby realizing the reciprocating sliding displacement of the screen box 25 along the arc-shaped slide groove 49.

[0035] The screen box 25 is in a swinging state when sliding back and forth along the arc-shaped slide groove 49, which can effectively shake the material in the screen box 25 so that the material falls after being screened by the screen.

[0036] Specifically, at least one collecting bin 47 is installed on the outer wall of the box body 1, and the screening component includes at least one screening assembly. The screening assembly includes a sieve plate 43, a third connecting rod 39, and a cam 40. The sieve plate 43 is tiltedly arranged inside the box body 1, and the sieve plate 43 is longitudinally slidably connected to the box body 1. A discharge port 46 is provided on one side wall of the box body 1. The lower end of the sieve plate 43 passes through the discharge port 46 on the box body 1, and the lower end edge of the sieve plate 43 is located above the collecting bin 47. The two ends of the third connecting rod 39 are rotatably connected to the inner side wall of the box body 1, the cam 40 is sleeved on the outer side wall of the third connecting rod 39 and the two are fixedly connected, and the cam 40 is located below the sieve plate 43 and the two are abutted. The motor 4 is transmission-connected to the third connecting rod 39, the motor 4 drives the third connecting rod 39 to rotate, and the third connecting rod 39 drives the cam 40 to rotate, and the cam 40 drives the sieve plate 43 to reciprocate and rise and fall during the rotation of the cam 40.

[0037] Among them, there are many sieve holes on the sieve plate 43. The collection bin 47 is used to collect the screened materials. The motor 4 drives the third connecting rod 39 to rotate, and the rotation of the third connecting rod 39 drives each cam 40 to rotate. The cam 40 pushes the sieve plate 43 to move up and down reciprocatingly during the rotation. After the coal-based activated carbon material falls on the sieve plate 43, the larger particles of the material roll along the inclined surface of the sieve plate 43 into the collection bin 47, and the smaller particles of the material fall through the sieve holes into the collection box 48 below the sieve plate 43. There can be multiple screening components, and the coal-based activated carbon material falls into the collection box 48 after being screened by at least one screening component.

[0038] More specifically, the screening assembly includes two support plates, which are fixedly mounted on the two inner side walls of the box body 1, and are respectively located below the two ends of the screen plate 43. A telescopic rod 42 is fixedly connected to the support plate, and one end of the telescopic rod 42 away from the support plate is hinged to the end of the screen plate 43. A spring 41 is sleeved on the outer side wall of the telescopic rod 42, and the upper end of the spring 41 abuts against the screen plate 43, and the lower end of the spring 41 abuts against the support plate.

[0039] The spring 41 and the telescopic rod 42 are used to vibrate the sieve plate 43. The cam 40 pushes the sieve plate 43 to move up and down, and the sieve plate 43 vibrates under the action of the spring 41 and the telescopic rod 42 during the lifting process, thereby enhancing the screening effect of the sieve plate 43.
