Description

Technical Field

[0001] The present invention relates to the technical field of carbon black granulators, in particular to a granulator for generating carbon black and a granulation process thereof. Background Art

[0002] Carbon black granulator is a machine specially used to process carbon black powder into granular equipment. Carbon black granulator mainly mixes water and carbon black and squeezes them into spherical particles through strong stirring and degassing. This equipment can be a wet granulator. It uses negative pressure and continuous granulation without adding chemical adhesives, reducing dust pollution and keeping the working environment clean. Carbon black granulator has a wide range of applications and is suitable for granulating materials such as spray carbon black, furnace carbon black, gas black, cracking carbon black, graphite, carbon nanotubes, etc.

[0003] Generally, carbon black granulation uses wet granulator and dry granulator. Before using wet granulator, water and carbon black need to be mixed and stirred by mixing machine, which makes the carbon black granulation process more complicated, prolongs the granulation time and reduces the granulation efficiency. When granulating carbon black, dry granulator can only form carbon black into one piece, and then crush the whole piece of carbon black into particles by grinding, which will generate a lot of dust and cause waste, and cannot meet actual needs.

[0020] A granulation process for a carbon black generating granulator comprises the following steps:

[0021] S1. Pour the carbon black powder into the feed box. The sweeping wheel rotates to drive the third and fourth pulleys, 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, it will be crushed into powder again after being ground by the grinding wheels.

[0022] S2. The cleaning wheel rotates continuously, and the bristles on the cleaning wheel are used to clean the carbon black attached to the surface of the pelletizing disk. At the same time, the excess carbon black inside the cleaning box is continuously pushed to one side of the pelletizing disk, and the excess carbon black continues to enter the interior of the pelletizing die hole, so that there is enough carbon black inside the pelletizing die hole;

[0023] S3. The piston squeezes the carbon black inside the pelletizing die hole into a round cake-shaped carbon black pellet. The pelletizing disk rotates continuously, pushing the carbon black inside the pelletizing die hole out of the pelletizing die hole, and the carbon black round cake falls into the inside of the collection box.

[0024] From the above, it can be seen that the granulator for carbon black production and the granulation process thereof provided by the present invention have the following technical effects.

[0025] First, as the granulation disk rotates continuously, the carbon black inside is squeezed out of the pelletizing die hole of the round cake. When it passes through the second extrusion roller, due to the design of the pressure-bearing groove, the pressure-bearing groove will squeeze the guide rod, so that the guide rod and the extrusion cylinder slide toward one end of the pelletizing die hole at the same time and squeeze the first spring and the second spring, so that the carbon black inside the pelletizing die hole is pushed out of the pelletizing die hole, 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 and stirring. At the same time, compared with the dry granulation method, there is no need for crushing and granulation, the amount of dust is small, and the utilization rate is high.

[0026] Second: by starting the motor, the main shaft is driven to rotate, thereby driving the second pulley and the first pulley to rotate, the middle rod and the right bevel gear drive the left bevel gear and the cleaning wheel to rotate, the granulation disk continuously rotates clockwise, and the carbon black continuously enters the interior of the multiple granulation die holes on the granulation disk. The cleaning wheel continuously rotates, and the bristles on the cleaning wheel are used to sweep away the carbon black attached to the surface of the granulation disk. 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 interior of the granulation die hole, so that there is enough carbon black inside the granulation die hole, which has the effect of cleaning the surface of the granulation disk and filling the carbon black inside the granulation die hole.

[0027] Third: by pouring the carbon black powder into the feed box, the sweeping 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, and 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 agglomerates, it will be crushed into powder again after being ground by the grinding wheel, and fall to 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, which has the effect of crushing the condensed carbon black.

[0028] Fourthly: When not in use, since the carbon black particles are small, they are easily adsorbed on the surface of the granulation disk. By starting the water pump, the water inside the pool is sucked out through the water inlet pipe, and the water is continuously used to clean the surface of the granulation disk through the water outlet pipe, which has the effect of reducing carbon black dust in subsequent use.

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

[0039] The present invention discloses a granulator for producing carbon black and a granulation process thereof. The granulator is mainly used for wet granulation. Before the use of the wet granulator, a mixing and stirring machine is required to mix water and carbon black, which makes the carbon black granulation step more complicated, prolongs the carbon black granulation time, and reduces the granulation efficiency. When the dry granulator granulates the carbon black, it can only form the carbon black in one piece and then crush the whole piece of carbon black into particles by pulverizing, resulting in a waste of raw materials and generating a large amount of dust.

[0041] A multi-stage punching mechanism is installed inside the pelletizing die hole 7, and the multi-stage punching mechanism is used to extrude and shape the carbon black;

[0042] A rotary wheel mechanism is installed on one side of the granulation disk 8, which is used to clean the carbon black on the surface of the granulation disk 8;

[0043] A crushing mechanism is installed on one side of the granulating disk 8, located on the top of the rotor mechanism, and is used to crush the carbon black that has condensed into agglomerates;

[0044] A cleaning mechanism is installed on the upper surface of the bottom plate 1 at the bottom of the main shaft 16. The cleaning mechanism is used to remove carbon black on the surface of the pelletizing disk 8 and the pelletizing die hole 7.

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

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

[0047] The second fixed plate 19 is fixedly connected to the upper surface of the base plate 1, and a mounting plate is fixedly connected to the upper surface of the base plate 1 near one end of the second extrusion roller 20. The mounting plate is rotatably connected to one end of the second extrusion roller 20, and 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 interior of the granulation die hole 7 with carbon black, the rotation of the granulation disk 8 is used to continuously transfer the carbon black inside the granulation die hole 7 downward. When the granulation die hole 7 passes through the first extrusion roller 17, due to the design of the spacing groove 48 and the extrusion groove 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 greater than the width of the spacing groove 48, the extrusion groove 49 on the first extrusion roller 17 will squeeze the extrusion cylinder 47, thereby squeezing the first spring 44 to drive the extrusion cylinder 47 and the guide rod 46 to move toward one end of the granulation die hole 7, squeezing the carbon black inside the granulation die hole 7. Due to the obstruction of the cleaning box 10 and the pressure block 11 outside the granulation die hole 7, the carbon black inside the granulation die hole 7 cannot be squeezed out, and the piston 42 extrude the carbon black inside the granulation die hole 7 to form round cake-shaped carbon black particles.

[0049] Furthermore, as the granulation disk 8 continuously rotates, the carbon black inside is squeezed into the granulation die hole 7 of the round cake and passes through the second extrusion roller 20. Due to the design of the pressure-bearing groove 50, the pressure-bearing groove 50 will squeeze the guide rod 46, so that the guide rod 46 and the extrusion cylinder 47 slide toward one end of the granulation die hole 7 at the same time and squeeze the first spring 44 and the second spring 45, so that the carbon black inside the granulation die hole 7 is pushed out of the granulation die hole 7, and the carbon black round cake falls into the inside of the collecting box 2. Compared with the wet granulation method, it has the effect of reducing carbon black dust without adding water and stirring. At the same time, compared with the dry granulation method, there is no need for crushing and granulation, the amount of dust is small, and the utilization rate is high.

At the same time, the excess carbon black inside the cleaning box 10 is continuously pushed to one side of the granulation disk 8, and the excess carbon black continues to enter the interior of the granulation die hole 7, so that there is enough carbon black inside the granulation die hole 7, which has the effect of cleaning the surface of the granulation disk 8 and filling the carbon black inside the granulation die hole 7.

[0054] A stopper 39 is provided inside the feed box 9, and a first sieve plate 38 is fixedly connected to the inner wall of one side of the feed box 9. A second sieve plate 40 is fixedly connected to the inner wall of one side of the feed box 9 at a position above the first sieve plate 38. A plurality of first sieve holes are provided on the upper surface of the second sieve plate 40, and a second sieve hole is provided on the upper surface of the first sieve plate 38.

[0055] In this embodiment, the carbon black powder is poured into the feed box 9, and the rotation of the sweeping wheel 30 drives 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, so that the grinding shaft 37 rotates. 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.

The scraper plate 14 is a rod with bent ends. The scraper plate 14 is positioned close to one side surface of the granulation disk 8. The scraper plate 14 is used to scrape the extruded carbon black from the surface of the granulation disk 8 to prevent the carbon black from adhering to one side surface of the granulation disk 8.

[0058] In this embodiment, due to the moisture in the air, some carbon black may have a certain viscosity after absorbing moisture, and may adhere to the surface of the piston 42 without falling into the inside of the water pool 3. Through the rotation of the granulation disk 8, the scraper plate 14 will scrape the carbon black cakes exposed outside the granulation die hole 7 from the piston 42, thereby achieving the effect of timely cleaning the carbon black on the outer surface of the piston 42 and the granulation disk 8.

[0059] Furthermore, 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, the water pump 28 is started to suck out the water inside the water pool 3 through the water inlet pipe 29, and the water is continuously used to clean the surface of the granulation disk 8 through the water outlet pipe 27, which has the effect of reducing carbon black dust in subsequent use.

[0060] Working principle: When in use, pour the carbon black powder into the feed box 9, and the rotation of the sweeping wheel 30 drives 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, so that the grinding shaft 37 rotates, and 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.

The carbon black is ground into a finer powder through the screening of the next grinding wheel 41, 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 set with a slope, 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 surface of one side of the granulation disk 8 through the discharge port at the bottom of one side of the feed box 9, which has the effect of crushing the carbon black condensed into a block. 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, and the intermediate rod 23 and the right bevel gear 22 drive the left bevel gear 21 and the cleaning wheel 30 to rotate. The granulation disk 8 continues to rotate clockwise, and the carbon black continues to enter the interior of the multiple granulation die holes 7 on the granulation disk 8. The cleaning wheel 30 rotates continuously, and the bristles on the cleaning wheel 30 are used to clean up the carbon black attached to the surface of the granulation disk 8. At the same time, the excess carbon black inside the cleaning box 10 is continuously pushed to one side of the granulation disk 8, and the excess carbon black continues to enter the interior of the granulation die hole 7. The granulating die hole 7 is filled with carbon black, so that there is enough carbon black inside the granulating die hole 7, which has the effect of cleaning the surface of the granulating plate 8 and filling the carbon black inside the granulating die hole 7. By filling the interior of the granulating die hole 7 with carbon black, the rotation of the granulating plate 8 is used to continuously transmit the carbon black inside the granulating die hole 7 downward. When the granulating die hole 7 passes through the first squeezing roller 17, due to the design of the spacing groove 48 and the squeezing groove 49 on the first squeezing roller 17, the guide rod 46 at one end of the first squeezing roller 17 passes through the spacing groove 48, and the guide rod 46 does not contact the first squeezing roller 17. Since the diameter of the extrusion cylinder 47 is greater than the width of the spacing groove 48, the extrusion groove 49 on the first squeezing roller 17 will squeeze the extrusion cylinder 47, thereby squeezing the first spring 44 to drive the extrusion cylinder 47 and the guide rod 46 to move toward one end of the granulating die hole 7, squeezing The carbon black inside the granulating die hole 7 cannot be squeezed out due to the obstruction of the cleaning box 10 and the pressure block 11 outside the granulating die hole 7. The piston 42 squeezes the carbon black inside the granulating die hole 7 into a round cake-shaped carbon black pellets. As the granulating disk 8 rotates continuously, the carbon black inside is squeezed into the round cake. When the granulating die hole 7 passes through the second extrusion roller 20, due to the design of the pressure groove 50, the pressure groove 50 will squeeze the guide rod 46, so that the guide rod 46 and the extrusion cylinder 47 slide toward one end of the granulating die hole 7 at the same time and squeeze the first spring 44 and the second spring 45, so that the carbon black inside the granulating die hole 7 is pushed out of the granulating die hole 7, and the carbon black round cake falls into the inside of the collecting box 2. Compared with the wet granulation method, it has the effect of reducing carbon black dust without adding water and stirring.At the same time, compared with the dry granulation method, there is no need for crushing and granulation, the amount of dust is small, and the utilization rate is high. Due to the moisture in the air, some carbon black may have a certain viscosity after absorbing moisture, and may adhere to the surface of the piston 42 and not fall into the inside of the water pool 3. Through the rotation of the granulation disk 8, the scraper plate 14 will scrape the carbon black cakes exposed outside the granulation die hole 7 from the piston 42, which has the effect of timely cleaning the carbon black on the outer surface 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 pool 3 is sucked out through the water inlet pipe 29, and the surface of the granulation disk 8 is continuously cleaned with water through the water outlet pipe 27, which has the effect of reducing carbon black dust in subsequent use.
