Premixing treatment system and process for thermally-cracked carbon black

Abstract

The invention discloses a premixing treatment system for thermally-cracked carbon black. The premixing treatment system comprises a machine shell and a condensation cavity fixedly formed in the side face of the machine shell, wherein a heating ring shell is fixedly arranged on the outer side of the machine shell, a first reaction cavity is formed in one side of an inner cavity of the machine shell, a second reaction cavity is formed in the other side of the inner cavity of the machine shell, two carbon black material ports and two modifier material ports fixedly communicate with the top end of the first reaction cavity, a second rotating wheel is arranged on the outer side of a connecting rod in a sleeving mode, two through holes in the second rotating wheel are in sliding connection with two sliding rods correspondingly, a second fixing sleeve is rotationally connected to the outer side of the second rotating wheel, and a second hydraulic telescopic cylinder is fixedly arranged between the first fixing sleeve and the second fixing sleeve. According to the invention, a self-rotating spiral swing gas phase mixing mechanism is adopted, so different gas state materials are stirred and mixed through spiral blades, and mixing effect is enhanced; and a pressure adjusting transfer structure is adopted, so the efficiency of the whole machining process is improved, and meanwhile, waste discharge is reduced.

Description

technical field [0001] The invention relates to the technical field of carbon black mixing equipment, in particular to a thermal cracking carbon black premixing treatment system and a process thereof. Background technique [0002] Thermal cracking carbon black is produced by pyrolysis of natural gas isolated from air and heated to 600°C. It is composed of a large number of spherical and oval carbons and a small amount of welded particles. It has large particle size, small specific surface area, low structure, easy dispersion, good fluidity, high Filling capacity and other characteristics, some rubber product manufacturers that do not require high performance mostly use imported or domestic natural gas semi-reinforced carbon black or spray carbon black for filling. The existing open thermal cracking device has realized continuous and stable production under normal pressure, but It is necessary to realize the high-value reuse of pyrolytic carbon black through a series of techn...

Problems solved by technology

[0003] However, in the existing carbon black production process, pre-mixing is often required before processing. However, pre-mixing requires the modifier to be mixed and adsorbed with the main material of carbon black during processing. At this time, the modifier needs to be After liquefaction, it is atomized again, and the carbon black is atomized at high temperature at the same time, so as to facilitate the modification and mixing of the two, so as to produce stable high-quality recycled carbon black. It is difficult for the atomized substances with different properties to attach and adsorb quickly, resulting in uneven adsorption of the atomized substances and the decline in the quality of carbon black after production.
