AI Technical Summary

Technical Problem

Existing waste tire pyrolysis carbon black production lines suffer from problems such as uneven airflow distribution, low scraping efficiency of the scraping system, and rapid wear of the scraper blades in their dust collection devices.

Method used

It adopts a 45° symmetrical dual-fan design to form an opposing airflow field, combined with a tapered feed pipe and a tapered discharge pipe design, uses spiral guide ribs to increase airflow speed, and adopts a four-scraper staggered layout. The scraper is a composite structure composed of a base, a reinforcing layer and a blade to improve scraping efficiency and reduce wear.

Benefits of technology

It improves airflow separation efficiency, enhances scraping efficiency, reduces scraper wear, and minimizes dust and metal contamination.
