Description

Technical Field

[0001] The present invention relates to the technical field of carbon black granulators, and particularly to a granulator for carbon black production and its granulation process. Background Art

[0002] A carbon black granulator is a machine specifically used to process carbon black powder into granular equipment. The carbon black granulator mainly mixes and extrudes water and carbon black into spherical particles through strong stirring and degassing. This equipment can be a wet granulator, which reduces dust pollution and keeps the working environment clean by using a negative pressure and continuous granulation method without adding chemical binders. The application range of carbon black granulators is wide, and they are suitable for granulating materials such as spray carbon black, furnace carbon black, gas black, pyrolytic carbon black, graphite, and carbon nanotubes.

[0003] Generally, wet granulators and dry granulators are used for carbon black granulation. Before using a wet granulator, a mixing and stirring machine is required to mix water and carbon black, which makes the carbon black granulation steps more complex, prolongs the carbon black granulation time, and reduces the granulation efficiency. When a dry granulator is used for carbon black granulation, it can only form the carbon black into a whole, and then crush the whole piece of carbon black into particles through crushing, which will generate a large amount of dust and cause waste, and cannot meet the actual needs.

[0018] In a preferred embodiment, the cleaning mechanism includes a water pump fixedly connected to the top edge of the water tank.

[0019] The collection mechanism includes a fixed rod fixedly connected to the inner wall of the collection box. One end of the fixed rod is fixedly connected to a scraping plate. The scraping plate is a rod bent at both ends. The position of the scraping plate is close to one side surface of the granulating disk. The scraping plate is used to scrape the extruded carbon black from the surface of the granulating disk to prevent the carbon black from adhering to one side surface of the granulating disk.

[0020] The granulation process of a granulator for carbon black production includes the following steps:

[0021] S1. Pour the carbon black powder into the feed box. The cleaning wheel rotates to drive the third pulley and the fourth pulley to rotate, thereby driving the lower bevel gear and the upper bevel gear to rotate, causing the grinding shaft to rotate. The rotation of the grinding shaft drives the two grinding wheels to rotate, continuously grinding the carbon black on the upper surface of the second sieve plate. If the carbon black absorbs moisture and condenses into lumps, after being ground by the grinding wheels, it will be re-crushed into powder.

[0022] S2. Through the continuous rotation of the cleaning wheel, the carbon black adhering to the surface of the granulation disk is swept off by the bristles on the cleaning wheel. At the same time, the excess carbon black inside the cleaning box is continuously pushed to one side of the granulation disk, and the excess carbon black continues to enter the inside of the granulation die holes, so that there is enough carbon black inside the granulation die holes.

[0023] S3. The piston extrudes the carbon black inside the granulation die holes into a formed round cake-shaped carbon black granule. As the granulation disk rotates continuously, the carbon black inside the granulation die holes is pushed out of the granulation die holes, and the carbon black round cake falls into the inside of the collection box.

[0024] As can be seen from the above, a granulator for carbon black production and its granulation process provided by the present invention have the following technical effects.

[0025] First: As the granulation disk rotates continuously, when the carbon black inside is extruded into a round cake and passes through the second extrusion roller in the granulation die holes, due to the design of the pressure-bearing groove, the pressure-bearing groove will extrude the guide rod, so that the guide rod and the extrusion cylinder slide towards one end of the granulation die holes simultaneously and extrude the first spring and the second spring, causing the carbon black inside the granulation die holes to be pushed out of the granulation die holes, and the carbon black round cake falls into the inside of the collection box. Compared with the wet granulation method, it has the effect of reducing carbon black dust without adding water for stirring. At the same time, compared with the dry granulation method, it does not require crushing and granulation, has a small amount of dust, and a high utilization rate.

[0026] Second: By starting the motor, driving the main shaft to rotate, thereby driving the second pulley and the first pulley to rotate, the intermediate rod and the right bevel gear drive the left bevel gear and the cleaning wheel to rotate. The granulation disk rotates clockwise continuously, and the carbon black continuously enters the inside of multiple granulation die holes on the granulation disk. Through the continuous rotation of the cleaning wheel, the carbon black adhering to the surface of the granulation disk is swept off by the bristles on the cleaning wheel. At the same time, the excess carbon black inside the cleaning box is continuously pushed to one side of the granulation disk, and the excess carbon black continues to enter the inside of the granulation die holes, so that there is enough carbon black inside the granulation die holes, achieving the effects of cleaning the surface of the granulation disk and filling the inside of the granulation die holes with carbon black.

[0027] Thirdly: By pouring carbon black powder into the feeding box, the cleaning wheel rotates to drive the third pulley and the fourth pulley to rotate, thereby driving the lower bevel gear and the upper bevel gear to rotate, causing the grinding shaft to rotate. The rotation of the grinding shaft drives the two grinding wheels to rotate, continuously grinding the carbon black on the upper surface of the second sieve plate. If the carbon black absorbs moisture and condenses into blocks, after being ground by the grinding wheels, it will be crushed into powder again, and will fall onto the upper surface of the first sieve plate through the screening of the second sieve plate. Through the grinding of the next grinding wheel, the carbon black is ground into finer powder, achieving the effect of crushing the condensed carbon black blocks.

[0028] Fourthly: When not in use, since the carbon black particles are small and easily adsorbed on the surface of the granulating disk, by starting the water pump, the water inside the water tank is sucked out through the water inlet pipe, and the surface of the granulating disk is continuously washed with water through the water outlet pipe, achieving the effect of reducing carbon black dust in subsequent use.

Specific implementation manner

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] A granulator for carbon black production and its granulation process disclosed by the present invention are mainly applied to the scenario where before using a wet granulator, a mixing and stirring machine needs to be used to mix and stir water and carbon black, making the steps of carbon black granulation more complex, prolonging the time of carbon black granulation, reducing the granulation efficiency, and when a dry granulator is used for carbon black granulation, it can only form carbon black integrally and then crush the whole block of carbon black into particles through crushing, resulting in waste of raw materials and generating a large amount of dust.

[0040] Refer to Figure 1 — Figure 8, A granulator for carbon black production and its granulation process, including a bottom plate 1. On the upper surface of the bottom plate 1, a collection box 2 is fixedly connected. On the upper surface of the bottom plate 1, on one side of the collection box 2, a water tank 3 is fixedly connected. On the upper surface of the bottom plate 1, on one side of the water tank 3, a first fixing plate 4 is fixedly connected. On one side of the first fixing plate 4, a motor 5 is fixedly connected. At one end of the output shaft of the motor 5, a main shaft 16 is fixedly connected. At one end of the main shaft 16, a granulation disk 8 is fixedly connected. On one side surface of the granulation disk 8, a plurality of granulation die holes 7 are arranged. At the edge of one end of the bottom plate 1, an auxiliary plate 13 is fixedly connected. On one side of the auxiliary plate 13, a pressure-bearing block 11 is fixedly connected. On one side of the auxiliary plate 13, near the pressure-bearing block 11, a pressure-bearing roller 12 is rotatably connected. On one side of the auxiliary plate 13, at the edge of the granulation disk 8, a first extrusion roller 17 is rotatably connected. At one end of the main shaft 16, near the granulation disk 8, a second fixing plate 19 is rotatably connected. On one side of the second fixing plate 19, at the bottom position of the main shaft 16, a fixing block 18 is fixedly connected. On one side of the fixing block 18, a second extrusion roller 20 is rotatably connected. On the outer surface of the first extrusion roller 17, an extrusion groove 49 is arranged. Near the extrusion groove 49 on the outer surface of the first extrusion roller 17, spacing grooves 48 are respectively arranged. On the outer surface of the second extrusion roller 20, a plurality of pressure-bearing grooves 50 are respectively arranged;

[0041] Inside the granulation die hole 7, a multi-stage stamping mechanism is installed, and the multi-stage stamping mechanism is used to extrude and form the carbon black;

[0042] On one side of the granulation disk 8, a runner mechanism is installed, and the runner mechanism is used to clean the carbon black on the surface of the granulation disk 8;

[0043] On one side of the granulation disk 8, at the top of the runner mechanism, a crushing mechanism is installed, and the crushing mechanism is used to crush the agglomerated carbon black;

[0044] On the upper surface of the bottom plate 1, at the bottom position of the main shaft 16, a cleaning mechanism is installed, and the cleaning mechanism is used to remove the carbon black on the surfaces of the granulation disk 8 and the granulation die hole 7;

[0045] On the upper surface of the bottom plate 1, on one side of the cleaning mechanism, a collection mechanism is installed, and the collection mechanism is used to collect the carbon black.

[0046] The multi-stage stamping mechanism includes a fixed cylinder 43 fixedly connected inside the granulation die hole 7. Inside the fixed cylinder 43, an extrusion cylinder 47 is slidably connected. Inside the extrusion cylinder 47, a guide rod 46 is slidably connected. One end of the guide rod 46, the part located inside the extrusion cylinder 47, is sleeved with a second spring 45. One end of the guide rod 46, the part located inside the fixed cylinder 43, is sleeved with a first spring 44. The other end of the guide rod 46 is fixedly connected with a piston 42.

[0047] The second fixing plate 19 is fixedly connected to the upper surface of the bottom plate 1. An installation plate is fixedly connected to a position on the upper surface of the bottom plate 1 near one end of the second extrusion roller 20. The installation plate is rotatably connected to one end of the second extrusion roller 20. The positions of the granulation die holes 7 are arranged radially from the center position of the granulation disk 8.

[0048] In this embodiment, by filling the inside of the granulation die hole 7 with carbon black and continuously conveying the carbon black inside the granulation die hole 7 downward by the rotation of the granulation disk 8. When the granulation die hole 7 passes through the first extrusion roller 17, due to the design of the spacing grooves 48 and the extrusion grooves 49 on the first extrusion roller 17, the guide rod 46 at one end of the first extrusion roller 17 passes through the spacing groove 48, and the guide rod 46 does not contact the first extrusion roller 17. Since the diameter of the extrusion cylinder 47 is larger than the width of the spacing groove 48, the extrusion groove 49 on the first extrusion roller 17 will extrude the extrusion cylinder 47, thereby extruding the first spring 44 to drive the extrusion cylinder 47 and the guide rod 46 to move towards one end of the granulation die hole 7, extruding the carbon black inside the granulation die hole 7. Due to the blocking of the cleaning box 10 and the pressure-bearing block 11 outside the granulation die hole 7, the carbon black inside the granulation die hole 7 cannot be extruded, and the piston 42 extrudes and forms the carbon black inside the granulation die hole 7 into round cake-shaped carbon black particles.

[0049] Furthermore, as the granulation disk 8 rotates continuously, when the granulation die hole 7 with the carbon black inside extruded into a round cake passes through the second extrusion roller 20, due to the design of the pressure-bearing groove 50, the pressure-bearing groove 50 will extrude the guide rod 46, thereby causing the guide rod 46 and the extrusion cylinder 47 to slide towards one end of the granulation die hole 7 simultaneously and extrude the first spring 44 and the second spring 45, pushing the carbon black inside the granulation die hole 7 out of the granulation die hole 7, and the carbon black round cake falls into the inside of the collection box 2. Compared with the wet granulation method, it has the effect of reducing carbon black dust without adding water for stirring. At the same time, compared with the dry granulation method, it does not require crushing and granulation, has a small amount of dust, and a high utilization rate.

[0050] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , in a preferred embodiment, the runner mechanism includes an installation frame 6 fixedly connected to the top end of the first fixing plate 4. One end of the installation frame 6 is rotatably connected through the middle rod 23. One end of the middle rod 23 is fixedly connected to a first belt pulley 24. The other end of the middle rod 23 is fixedly connected to a right bevel gear 22. One end of the main shaft 16 is fixedly connected to a second belt pulley 26 at the bottom position of the first belt pulley 24. A first belt 25 is arranged between the second belt pulley 26 and the first belt pulley 24. A cleaning box 10 is fixedly connected to the upper surface of the pressure-bearing block 11. A runner shaft is rotatably connected through the inside of the cleaning box 10. A cleaning wheel 30 is fixedly connected to the outer wall of the runner shaft.

[0051] The outer wall of the cleaning wheel 30 is provided with bristles. The bristles have a certain toughness. One end of the rotating wheel shaft is fixedly connected with a left bevel gear 21. The right bevel gear 22 meshes with the left bevel gear 21. The bristles are in direct contact with the bristles on the granulating disc 8.

[0052] In this embodiment, by starting the motor 5, the main shaft 16 is driven to rotate, thereby driving the second belt pulley 26 and the first belt pulley 24 to rotate. The intermediate rod 23 and the right bevel gear 22 drive the left bevel gear 21 and the cleaning wheel 30 to rotate. The granulating disc 8 rotates continuously clockwise. Carbon black continuously enters the inside of a plurality of granulating die holes 7 on the granulating disc 8. By the continuous rotation of the cleaning wheel 30, the carbon black attached to the surface of the granulating disc 8 is cleaned by the bristles on the cleaning wheel 30. At the same time, the excess carbon black inside the cleaning box 10 is continuously pushed to one side of the granulating disc 8. The excess carbon black continues to enter the inside of the granulating die holes 7, so that there is enough carbon black inside the granulating die holes 7, achieving the effects of cleaning the surface of the granulating disc 8 and filling the inside of the granulating die holes 7 with carbon black.

[0053] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In a preferred embodiment, the crushing mechanism includes a third belt pulley 31 fixedly connected to the other end of the rotating wheel shaft. One side outer wall of the cleaning box 10 is rotatably connected with an auxiliary rod 34. One end of the auxiliary rod 34 is fixedly connected with a fourth belt pulley 33. The other end of the auxiliary rod 34 is fixedly connected with a lower bevel gear 35. A second belt 32 is arranged between the fourth belt pulley 33 and the third belt pulley 31. The top of the cleaning box 10 is fixedly connected with a feed box 9. The bottom of the feed box 9 is observed and rotatably connected through a grinding shaft 37. The bottom end of the grinding shaft 37 is fixedly connected with an upper bevel gear 36. The top end of the grinding shaft 37 is respectively rotatably connected with two grinding wheels 41.

[0054] A baffle 39 is arranged inside the feed box 9. A first sieve plate 38 is fixedly connected to one side inner wall of the feed box 9. A second sieve plate 40 is fixedly connected to one side inner wall of the feed box 9 at a position above the first sieve plate 38. A plurality of first sieve holes are arranged on the upper surface of the second sieve plate 40. Second sieve holes are arranged on the upper surface of the first sieve plate 38. The grinding wheels 41 are respectively in contact with the upper surfaces of the first sieve plate 38 and the second sieve plate 40. A plurality of auxiliary holes are arranged at the bottom of the feed box 9 at a position above the cleaning wheel 30. An outlet is arranged at one side bottom of the feed box 9.

[0055] In this embodiment, carbon black powder is poured into the feed box 9. The cleaning wheel 30 rotates to drive the third pulley 31 and the fourth pulley 33 to rotate, thereby driving the lower bevel gear 35 and the upper bevel gear 36 to rotate, causing the grinding shaft 37 to rotate. The rotation of the grinding shaft 37 drives the two grinding wheels 41 to rotate, continuously grinding the carbon black on the upper surface of the second sieve plate 40. If the carbon black absorbs moisture and condenses into lumps, after being ground by the grinding wheel 41, it will be crushed into powder again, and will fall onto the upper surface of the first sieve plate 38 through the screening of the second sieve plate 40. Through the grinding of the next grinding wheel 41, the carbon black is ground into finer powder, and falls to the bottom of the feed box 9 through the screening of the first sieve plate 38. The bottom of the feed box 9 is provided with an inclination, and the carbon black powder will slide to the position of the auxiliary hole. Part of the carbon black will fall onto the cleaning wheel 30 through the auxiliary hole, and the other carbon black contacts the side surface of the granulating disc 8 through the discharge port at the bottom of one side of the feed box 9, achieving the effect of crushing the carbon black that has condensed into lumps.

[0056] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in a preferred embodiment, the cleaning mechanism includes a water pump 28 fixedly connected to the top edge of the water tank 3. The upper surface of the water pump 28 is inserted with a water outlet pipe 27, and the lower surface of the water pump 28 is inserted with a water inlet pipe 29. Both the water inlet pipe 29 and the water outlet pipe 27 are made of a rigid plastic. The top end of the water outlet pipe 27 is arranged at a position close to one side of the granulating disc 8.

[0057] The collection mechanism includes a fixing rod 15 fixedly connected to the inner wall of the collection box 2. One end of the fixing rod 15 is fixedly connected with a scraping plate 14. The scraping plate 14 is a rod with both ends bent. The position of the scraping plate 14 is close to the side surface of the granulating disc 8. The scraping plate 14 is used to scrape the extruded carbon black from the surface of the granulating disc 8 to prevent the carbon black from adhering to the side surface of the granulating disc 8.

[0058] In this embodiment, since there is moisture in the air, some carbon black may have a certain viscosity after adsorbing moisture and may adhere to the surface of the piston 42 without falling into the interior of the water tank 3. Through the rotation of the granulating disc 8, the scraping plate 14 scrapes the carbon black cake exposed outside the granulating die holes 7 from the piston 42, achieving the effect of timely cleaning the carbon black on the outer surfaces of the piston 42 and the granulating disc 8.

[0059] Furthermore, since the carbon black particles are small and easily adsorbed on the surface of the granulating disc 8, when the equipment is not in use, by starting the water pump 28, the water inside the water tank 3 is sucked out through the water inlet pipe 29, and the surface of the granulating disc 8 is continuously washed with water through the water outlet pipe 27, achieving the effect of reducing carbon black dust in subsequent use.

[0060] Working principle: When in use, pour carbon black powder into the feeding box 9. The cleaning wheel 30 rotates to drive the third pulley 31 and the fourth pulley 33 to rotate, thereby driving the lower bevel gear 35 and the upper bevel gear 36 to rotate, causing the grinding shaft 37 to rotate. The rotation of the grinding shaft 37 drives the two grinding wheels 41 to rotate, continuously grinding the carbon black on the upper surface of the second sieve plate 40. If the carbon black absorbs moisture and condenses into lumps, after being ground by the grinding wheel 41, it will be crushed back into powder again, and fall onto the upper surface of the first sieve plate 38 through the screening of the second sieve plate 40. Through the grinding of the next grinding wheel 41, the carbon black is ground into finer powder, and falls to the bottom of the feeding box 9 through the screening of the first sieve plate 38. The bottom of the feeding box 9 is provided with an inclination, and the carbon black powder will slide to the position of the auxiliary hole. Part of the carbon black falls onto the cleaning wheel 30 through the auxiliary hole, and the other carbon black contacts the side surface of the granulating disc 8 through the discharge port at the bottom of one side of the feeding box 9, achieving the effect of crushing the carbon black that has condensed into lumps. By starting the motor 5, the main shaft 16 is driven to rotate, thereby driving the second pulley 26 and the first pulley 24 to rotate. The intermediate rod 23 and the right bevel gear 22 drive the left bevel gear 21 and the cleaning wheel 30 to rotate. The granulating disc 8 rotates clockwise continuously, and the carbon black continuously enters the interior of the multiple granulating die holes 7 on the granulating disc 8. Through the continuous rotation of the cleaning wheel 30, the carbon black attached to the surface of the granulating disc 8 is swept off by the bristles on the cleaning wheel 30. At the same time, the excess carbon black inside the cleaning box 10 is continuously pushed towards one side of the granulating disc 8, and the excess carbon black continues to enter the interior of the granulating die holes 7, making there be enough carbon black inside the granulating die holes 7, achieving the effects of cleaning the surface of the granulating disc 8 and filling the interior of the granulating die holes 7 with carbon black. By filling the interior of the granulating die holes 7 with carbon black, the rotation of the granulating disc 8 continuously conveys the carbon black inside the granulating die holes 7 downward. When the granulating die holes 7 pass through the first extrusion roller 17, due to the design of the spaced grooves 48 and the extrusion grooves 49 on the first extrusion roller 17, the guide rod 46 at one end of the first extrusion roller 17 passes through the spaced grooves 48, and the guide rod 46 does not contact the first extrusion roller 17. Since the diameter of the extrusion cylinder 47 is larger than the width of the spaced grooves 48, the extrusion grooves 49 on the first extrusion roller 17 will extrude the extrusion cylinder 47, thereby extruding the first spring 44 to drive the extrusion cylinder 47 and the guide rod 46 to move towards one end of the granulating die hole 7, extruding the carbon black inside the granulating die hole 7. Due to the obstruction of the cleaning box 10 and the bearing block 11 outside the granulating die hole 7, the carbon black inside the granulating die hole 7 cannot be extruded, and the piston 42 extrudes and forms the carbon black inside the granulating die hole 7 into round cake-shaped carbon black particles. As the granulating disc 8 rotates continuously, when the granulating die hole 7 with the carbon black inside being extruded into a round cake passes through the second extrusion roller 20, due to the design of the bearing groove 50, the bearing groove 50 will extrude the guide rod 46, thereby causing the guide rod 46 and the extrusion cylinder 47 to slide towards one end of the granulating die hole 7 simultaneously and extrude the first spring 44 and the second spring 45, pushing the carbon black inside the granulating die hole 7 out of the granulating die hole 7, and the carbon black round cake falls into the interior of the collection box 2. Compared with the wet granulation method, it achieves the effect of reducing carbon black dust without the need for water stirring.Meanwhile, compared with the dry granulation method, there is no need for crushing and granulation, the dust amount is small, and the utilization rate is high. Since there is moisture in the air, some carbon black may have a certain viscosity after adsorbing moisture and may adhere to the surface of the piston 42 without falling into the interior of the water tank 3. Through the rotation of the granulation disk 8, the scraping plate 14 scrapes off the carbon black cake exposed outside the granulation die holes 7 from the piston 42, achieving the effect of timely cleaning the carbon black on the outer surfaces of the piston 42 and the granulation disk 8. Since the carbon black particles are small, they are easily adsorbed on the surface of the granulation disk 8. When the equipment is not in use, by starting the water pump 28, the water inside the water tank 3 is sucked out through the water inlet pipe 29, and the surface of the granulation disk 8 is continuously washed with water through the water outlet pipe 27, achieving the effect of reducing carbon black dust in subsequent use.
