Problems solved by technology

Due to the technical blockade of China by foreign countries, there is currently no domestic technical ability to solve this problem. How to reduce the proportion of coke particles in carbon black has always been a research topic for domestic carbon black manufacturers.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] See Figure 1~3 , a carbon black classification device, comprising a cylinder 1, the cylinder 1 is a hollow cylinder with an upper end open and a lower end closed, and the upper and lower ends of the cylinder 1 have upper and lower passages 10, 12 respectively .

[0019] The side wall of the cylinder 1 is also provided with 6 through grooves 14, and the 6 through grooves 14 are connected with a second carbon black collection device (the second carbon black collection device is not shown in the figure). Of course, the number of the 14 through slots is not limited to 6, but can also be other numbers.

[0020] The side wall of the cylinder 1 is provided with a lower passage 12, and the angle between the lower passage 12 and the lower end of the cylinder is less than 90 degrees, so that the carbon black fume will quickly go around the defle...

Abstract

The invention discloses a carbon black grading device, which comprises a barrel, wherein the upper and lower ends of the barrel are provided with upper and lower channels; the side wall of the barrel is provided with a through groove; the lower channel of the barrel is connected with a carbon black reaction furnace; carbon black flue gas enters the barrel through the carbon black reaction furnace; the upper channel of the barrel is connected with a first carbon black collecting device; the through groove is connected with a second carbon black collecting device; the carbon black grading device also comprises a guiding device which comprises a guiding column; and guiding plates are wound on the outer side wall of the guiding column in a spiral rising mode. The guiding plates throw out impurities with larger specific gravity in the carbon black from the through groove on the side wall of the barrel by means of centrifugal force, so that the heavier impurities (mainly granular coke) in the carbon black are greatly reduced, and the quality of the carbon black is obviously improved.

Description

technical field [0001] The present invention relates to a kind of carbon black preparation, specifically, the present invention relates to a kind of carbon black classifying device. Background technique [0002] Carbon black is a light, loose and very fine black powder whose main component is amorphous carbon. It has a very large specific surface area, ranging from 10-3000m2 / g. Products obtained by incomplete combustion or thermal decomposition under certain conditions (with greater adhesion). Carbon black has a wide range of applications. It can be used as a black dye to make Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber and plays an important role in the industrial field. [0003] Traditionally, in the carbon black production process, air and fuel are burned in a reactor, and the raw materials are sprayed into the burning flame after being atomized, and carbon black is generated by high-temperature pyrolysis. Carbon black is sus...
