Abstract

[0002] Carbon black particles are a black powdery substance composed primarily of carbon with small amounts of oxygen, hydrogen, and sulfur. These particles are approximately spherical with a particle size ranging from 10 to 500 microns. Carbon black is formed through the incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. It is often used as a reinforcing agent and filler in rubber processing and is an important material in the rubber industry.
[0003] Carbon black granulation technology includes primary carbon black granulation and pyrolytic carbon black granulation, which aims to solve the environmental pollution problems that may be caused by powdered carbon black and meet customers' needs for carbon black form. Dust-free carbon black is a fine powder produced by incomplete combustion of carbon-containing raw materials (mainly petroleum), and its appearance is pure black granules or powder.
[0004] However, the existing carbon black particles are cooled by air cooling, which takes a long time and easily causes the carbon black particles to splash, requiring secondary or multiple collections; therefore, it does not meet the existing needs. In this regard, we propose a rapid cooling device for dried regenerated carbon black particles. Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.
[0018] like Figures 1 to 3 As shown, a rapid cooling device for dried regenerated carbon black particles is shown. The inner sides of the top ends of the two support frames 1 are rotatably connected with support shafts 2. A rotating drum 3 is fixed between the two supporting shafts 2. A rotating gear 6 is fixed to the outside of the rotating drum 3. A driving gear 5 is meshed and connected below the rotating gear 6. A driving motor 4 is fixed to one end of the driving gear 5. A sealed hatch 7 is detachably installed at one end of the rotating drum 3. Two end cooling plates 10 are installed inside the rotating drum 3. A cooling inner drum 11 is fixed between the two end cooling plates 10. One of the cooling inner drums 11 is fixed to the inner side of the rotating drum 3. A cold air inlet pipe 8 is inserted through the middle of each supporting shaft 2, and one end of the cold air inlet pipe 8 is inserted into one of the end cooling plates 10. A cold air recovery pipe 9 is inserted through the middle of the other supporting shaft 2, and one end of the cold air recovery pipe 9 is inserted into the other end cooling plate 10. The low-temperature cooling gas is transported into the end cooling plate 10 and the interior of the cooling inner drum 11 through the cold air inlet pipe 8 to reduce the temperature of the cooling inner drum 11. The cooling inner drum 11 after the temperature is reduced is used to cool the carbon black particles placed in the rotating drum 3.
[0019] A connecting air hole 12 is provided at the center of the two end cooling plates 10, and one end of the cold air inlet pipe 8 and the cold air recovery pipe 9 is inserted into the inner side of the connecting air hole 12. A plurality of connecting air channels 13 distributed in a circular array around the axis of the end cooling plate 10 are provided on the outer side of the connecting air hole 12. A plurality of docking air holes 15 are provided at both ends of the cooling inner drum 11. The docking air holes 15 are aligned with the ports of the connecting air channels 13 and the docking air holes 15 are distributed in a circular array around the axis of the cooling inner drum 11. The low-temperature cooling gas transported by the cold air inlet pipe 8 is delivered into the interior of the cooling inner drum 11 by utilizing the connecting air holes 12, the connecting air channels 13 and the docking air holes 15, and the cold-cut gas that has absorbed heat is discharged from the cooling inner drum 11 through the docking air hole 15 at the other end of the cooling inner drum 11 and the connecting air holes 12 and the connecting air channels 13 inside the other end cooling plate 10.
[0020] A cooling air bin 14 is provided inside the cooling inner drum 11, and the cooling air bin 14 is connected to the connecting air duct 13 through the docking air hole 15. A thermal insulation pad 16 is installed on the inner side of the cooling air bin 14, and the thermal insulation pad 16 is bonded to the inner wall surface of the cooling air bin 14 close to the rotating drum 3. The thermal insulation pad 16 is used to isolate the temperature of the low-temperature cooling gas inside the cooling air bin 14, thereby preventing the temperature of the low-temperature cooling gas from being transferred to the rotating drum 3 through the cooling inner drum 11, resulting in a decrease in the cooling effect of the device.
[0021] Working principle: First, open the sealed hatch 7 at the end of the rotating drum 3, add the carbon black particles to be cooled into the rotating drum 3, so that the carbon black particles fall on the inside of the cooling inner drum 11, then power on the driving motor 4 and start driving the driving gear 5 and the rotating gear 6 to rotate. At this time, the rotating gear 6 drives the rotating drum 3 and the cooling inner drum 11 to rotate at the same time. When the cooling inner drum 11 rotates, the carbon black particles roll on the inside of the cooling inner drum 11. At this time, the low-temperature cooling gas is injected into the end cooling plate 10 through the cold air inlet pipe 8. After entering the end cooling plate 10, the low-temperature cooling gas passes through the connecting air hole 12, the connecting air duct 13 and the end of the cooling inner drum 11. The low-temperature cooling gas enters the cooling air bin 14 through the docking air hole 15 at the other end of the cooling inner drum 11, and the low-temperature cooling gas reduces the temperature of the cooling inner drum 11. The cooling inner drum 11 after the temperature is reduced absorbs the heat in the carbon black particles rolling inside it, and the heat absorbed by the cooling inner drum 11 is absorbed by the low-temperature cooling gas inside the cooling air bin 14, and the temperature of the cooling inner drum 11 is kept constant. Subsequently, the low-temperature cooling gas after absorbing the heat enters the other end cooling plate 10 from the docking air hole 15 at the other end of the cooling inner drum 11, and finally the low-temperature cooling gas that absorbs the heat is discharged from the cold air recovery pipe 9 to the discharge device, which quickly reduces the temperature of the carbon black particles, and the carbon black particles will not splash during the cooling process.
[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
