[0027] Example

[0028] See also Figure 1-Figure 6 As shown, this embodiment provides a carbon black secondary rapid cooling device, including a mounting assembly 10, a stirring assembly 20 is provided at the center of the mounting assembly 10, the stirring assembly 20 is used to transfer the high-temperature carbon particles to be cooled accumulated at the bottom to a higher place, the mounting assembly 10 is wrapped with a heat exchange assembly 30 on the periphery, which is used to increase the path for the coolant to pass through the same space, a conveying assembly 40 is provided on one side of the heat exchange assembly 30, the conveying assembly 40 is connected to the mounting assembly 10, and the conveying assembly 40 is used to extract the cooled carbon particles.

[0029] Working principle: When the carbon black secondary rapid cooling device provided by the utility model is used, the stirring component 20 is used to transfer the high-temperature carbon particles to be cooled accumulated at the bottom to a higher place, the heat exchange component 30 is used to increase the path of the coolant passing through the same space, and then the conveying component 40 is used to extract the cooled carbon particles.

[0030] In order to transfer the high-temperature carbon particles to be cooled accumulated at the bottom to a higher place, the mounting assembly 10 includes a quenching kettle 11, a kettle cover 12 is provided on the top of the quenching kettle 11, a mounting seat 13 is provided at the top center of the kettle cover 12, and a material taking port 14 is provided on one side of the mounting seat 13 of the kettle cover 12; the stirring assembly 20 includes a motor 21 arranged on the mounting seat 13, the motor 21 is coaxially connected to a main rod 22 in the quenching kettle 11, and a maneuvering paddle 23 is coaxially connected to the top of the main rod 22, and the radius of the maneuvering paddle 23 gradually decreases from bottom to top; after the power is turned on, the motor 21 drives the main rod 22 to drive the maneuvering paddle 23 coaxially connected thereto to rotate, and since the maneuvering paddle 23 is arranged to have a radius that gradually decreases from bottom to top, the high-temperature carbon particles at the bottom are transferred to a higher place by the maneuvering paddle 23, and the high-temperature carbon particles after rising lose their supporting force due to the reduction in the radius of the maneuvering paddle 23, and thus fall to the bottom again, and this cycle continues.

[0031] In order to increase the number of paths through which the coolant passes in the same space, the heat exchange assembly 30 includes a heat exchange arm 31 that is sleeved on the outer periphery of the quenching kettle 11, and a threaded pipe 32 is opened in the heat exchange arm 31. The threaded pipe 32 is provided with interfaces 33 at both ends of the heat exchange arm 31; the threaded pipe 32 opened in the heat exchange arm 31 is in a continuously rising state, ensuring that the coolant passes through more paths in a limited space, thereby increasing the cooling effect.

[0032] In order to extract the cooled carbon particles, the conveying assembly 40 includes a suction pipe 41 arranged in the material taking port 14, a power pipe 42 and an outlet pipe 43 connected to the outside of the material taking port 14, a sieve plate 45 is provided between the power pipe 42 and the outlet pipe 43, and an extraction pump 44 is connected to the end of the power pipe 42 away from the suction pipe 41; after the carbon particles are cooled, the power of the extraction pump 44 is turned on, and the extraction pump 44 forms a negative pressure in the suction pipe 41 and the power pipe 42, and then extracts the carbon particles in the quenching kettle 11 into the outlet pipe 43. The sieve plate 45 can prevent the carbon particles from being sucked into the power pipe 42 and causing blockage of the pipeline.

[0033] When the carbon black secondary quenching device provided in the utility model is used, the stirring assembly 20 is used to transfer the high-temperature carbon particles to be cooled accumulated at the bottom to a higher place. Specifically, after the power is turned on, the motor 21 drives the main rod 22 to drive the transfer paddle 23 coaxially connected thereto to rotate. Since the transfer paddle 23 is set to have a radius that gradually decreases from bottom to top, the high-temperature carbon particles at the bottom are transferred to a higher place by the transfer paddle 23. After rising, the high-temperature carbon particles lose their supporting force due to the reduction in the radius of the transfer paddle 23, and thus fall to the bottom again, and this process is repeated continuously; through the heat exchange assembly 30 Increase the paths through which the coolant passes in the same space. Specifically, the threaded pipe 32 opened in the heat exchange arm 31 is in a continuously rising state, ensuring that the coolant passes through more paths in a limited space, thereby increasing the cooling effect. The conveying component 40 is then used to extract the cooled carbon particles. Specifically, after the carbon particles are cooled, the power of the extraction pump 44 is turned on. The extraction pump 44 forms a negative pressure in the suction pipe 41 and the power pipe 42, and then the carbon particles in the quenching kettle 11 are extracted into the outlet pipe 43. The sieve plate 45 can prevent the carbon particles from being sucked into the power pipe 42 and causing blockage in the pipeline.
