Description

Technical Field

[0001] The invention relates to the technical field of carbon black production, in particular to an explosion-proof dryer for rapid cooling of carbon black. Background Art

[0002] Carbon black, also known as carbon black, is a kind of amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area. It is the product of incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. The one made from natural gas is called "gas black", the one made from oil is called "lamp black", and the one made from acetylene is called "acetylene black". In addition, there are "channel black" and "furnace black". According to the performance of carbon black, there are "reinforcement carbon black", "conductive carbon black" and "wear-resistant carbon black". It can be used as a black dye for the manufacture of Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber. In the production process of carbon black, the carbon black flue gas after rapid cooling is jacketed with water cooling in the flue and then cooled by spraying water in the cooling tower after the reactor. After cooling, the carbon black needs to be dried, but the carbon black particles are very fine and difficult to dry during the cooling process. Make sure that every carbon black particle is sprayed. When there is carbon black that has not been sprayed and collides and rubs with the dryer in the drying box, it is easy to explode. In addition, a large amount of carbon black gathers together, which will affect the dryness of the internal carbon black. On the other hand, the traditional drying chamber uses appropriate airflow to blow up the carbon black after drying. At this time, the gravity of the dry carbon black is less than the buoyancy, which can facilitate the collection of the dry carbon black, while the still wet carbon black is difficult to float, which is convenient for users to collect and perform secondary drying. However, this method is difficult to ensure that there is dry and heavy carbon black in the wet carbon black. When the heavy carbon black and the wet carbon black are gathered together for secondary treatment, it is easy to increase the processing volume of the secondary treatment, which wastes energy and is more time-consuming and labor-intensive. In view of this, an explosion-proof and rapid cooling carbon black dryer is proposed here to solve the above problems. Summary of the invention

[0027] In summary, when using the explosion-proof dryer for rapid cooling of carbon black, the user first needs to start the first fan 6, and then introduce the rapidly cooled carbon black into the inner cavity of the explosion-proof box 1, and then start the first dryer 7 and the first servo motor 8, and use the first servo motor 8 to drive the rotating rod 9 to rotate, and use the rotating rod 9 to drive the eccentric wheel 10 to rotate, and then the eccentric wheel 10 drives the vibrating screen 14, and the elastic force provided by the reset spring 13 can make the vibrating screen 14 vibrate, and the carbon black is dried for the first time, and then the carbon black will enter the inner cavity of the centrifugal cylinder 23, and at this time, the second servo motor 15 needs to be started to drive the first driving wheel 16 and the second driving wheel 19, and then the first crawler 17 and the second crawler 20 drive the first driven wheel 18 and the second driven wheel 2 1 is driven, thereby causing the centrifugal cylinder 23 to rotate, so as to realize centrifugal drying of the carbon black and reduce the moisture inside the carbon black. At the same time, the power rod 22 will drive the stirring blade 25 to rotate, so as to stir the carbon black and realize that the carbon black can be evenly heated. After the carbon black is dried for the second time, it will be introduced into the inner cavity of the drying cylinder 3 by the stirring blade 25, and then the driving motor 28 is started to introduce the carbon black from the drying cylinder 3 into the interior of the grinding box 4. The drying cylinder 3 is used to realize the third drying. The carbon black entering the grinding box 4 will be crushed by the grinding roller 32 to prevent the presence of large-mass carbon black from mixing into the wet carbon black, and at the same time crush the large particles of wet carbon black. Finally, starting the second fan 31 will blow the dry carbon black out from the discharge port 5, while the wet carbon black needs to be collected and processed by opening the discharge door 33.
