Description

Technical Field

[0001] This invention relates to the field of carbon black production technology, specifically to a carbon black reprocessing device and control method for carbon black production. Background Technology

[0002] Carbon black is a black powdery substance produced by the incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is elemental carbon, with small amounts of oxygen, hydrogen, and sulfur. Carbon black particles are nearly spherical, with a particle size ranging from 10 to 500 μm. Many particles often fuse or aggregate into three-dimensional dendritic or fibrous aggregates. In rubber processing, it is added to rubber as a reinforcing agent and filler through compounding. A carbon black reprocessing unit is a specially designed device for carbon black production, aiming to improve production efficiency and product quality.

[0003] However, existing carbon black recycling devices often have fewer filter components, making it difficult to separate carbon black that meets the standards, which can easily affect the quality. Moreover, the grinding methods are relatively simple, resulting in low-quality carbon black produced. In addition, the filter parts need to be frequently disassembled for cleaning to prevent clogging, which affects work efficiency. Furthermore, some carbon black is left outside the equipment after each production run, making it inconvenient to recycle. Summary of the Invention

[0028] By incorporating a rotary drive assembly and a cleaning assembly, the filter bags that have been screened can be moved to the bottom of the cleaning assembly after screening, while the unscreened filter bags can be moved to the screening position, thus cleaning the filter bags in a timely manner without affecting the working efficiency of the screening assembly.

[0029] By setting multiple grinding rollers with different mesh sizes in the grinding assembly to grind carbon black sequentially, the carbon black can be ground to a specified mesh size, ensuring that the quality of the carbon black is more stable.

[0030] The grinding and feeding assembly recovers the carbon black powder that is still not screened at the end of the multi-stage filtration equipment into the feeding equipment, thereby enabling full processing of carbon black and high material utilization.

[0031] This carbon black recycling device and control method for carbon black production can not only separate qualified carbon black from unqualified carbon black multiple times, but also grind carbon black to a specified mesh size using various different grinding rollers, ensuring stable carbon black quality and improving product quality; it can also clean filter bags while working, without affecting work efficiency; and it can also ensure that carbon black is constantly circulating inside the equipment until processing is complete, resulting in high material utilization and low scrap rate.
