Description

Technical Field

[0001] This utility model relates to the technical field of cooling equipment for carbon black production, and in particular to a multi-stage airflow cooling device for carbon black production. Background Technology

[0002] The charcoal production process involves converting raw materials into carbon black through high-temperature pyrolysis. The carbon black gas stream undergoes a series of cooling stages to rapidly reduce its temperature, ensuring the quality and performance of the carbon black. Multi-stage airflow cooling equipment plays a crucial role in this process, effectively reducing the airflow temperature and ensuring the cooling and stabilization of the carbon black particles. This equipment uses a multi-stage cooling method to gradually reduce the airflow temperature at different stages, thereby promoting the cooling of carbon black particles to a suitable temperature range and providing favorable conditions for subsequent storage and processing.

[0003] Traditional multi-stage airflow cooling equipment for charcoal production typically consists of multiple cooling sections, each equipped with a spray cooling device, cooling tower, or heat exchanger, using water or air as the cooling medium. As the airflow passes through the cooling section, its temperature is reduced by spraying coolant or exchanging heat with the cooling medium. In addition, the equipment includes airflow distributors, fans, and gas control systems to ensure uniform airflow distribution and effective cooling, while also ensuring the separation and cooling of carbon black particles.

[0004] Traditional multi-stage airflow cooling equipment for charcoal production relies heavily on gravity or natural flow for cooling, resulting in uneven airflow velocity and cooling efficiency. During multi-stage cooling, variations in airflow velocity and temperature lead to incomplete cooling, especially at the end of the cooling stage, where carbon black particles fail to cool completely due to slow cooling rates. Incompletely cooled carbon black particles cause adhesion and aggregation, potentially affecting the physical properties of the carbon black and the quality of subsequent processing. Utility Model Content

This helps to improve the particle size uniformity, purity and quality consistency of carbon black, optimize production efficiency and reduce resource waste. Attached Figure Description

An upper screening chamber 11 is fixedly connected to the side wall of the conveying pipe 10.

[0036] Working principle: When carbon black particles are produced, they enter the cooling tower 2 through the feed pipe 1. Motor 4 is started, driving the rotating torsion plate 5 to rotate, which in turn drives the electric motor 8 to rotate in the rotating support 7. The rotation of the electric motor 8 causes the rotating support 7 to rotate within the fixed support 6, ultimately causing the fan blades 9 to rotate within the cooling tower 2. Multiple cooling components complete the multi-stage cooling of the carbon black particles. The cooled carbon black particles enter the upper screening chamber 11 through the conveying pipe 10. Motor 12 is started, and the fixed rod 13 begins to rotate, driving the rotating disc 14 to rotate. The movement of the disc 14 provides thrust to the power rod 17. Since multiple rotatable torsion bars 20 are connected between the upper screening chamber 11 and the lower screening chamber 16, when the power rod 17 pushes the fixed rod 18, it causes the upper screening chamber 11 to slide. Therefore, when carbon black particles enter the upper screening chamber 11, they are carried forward and slide. When they pass through the fine filter screen 21, the particles are screened into four different diameter particles and enter different areas. The smallest diameter particles directly enter the pipe, and the other three diameters are screened again in order from small to large until all carbon black particles enter the storage silo 27 through the conveying pipe 26.
