Description

Technical Field

[0001] The utility model relates to the technical field of carbon black granulation, in particular to a carbon black granulation and classification device. Background Art

[0002] Carbon black is a kind of amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area ranging from 10-3000m2 / g. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. The structure of carbon black is expressed by the degree to which the carbon black particles are aggregated into chains or grapes. Carbon black composed of agglomerates composed of the size, shape and number of particles in each agglomerate is called high-structure carbon black. After the carbon black is granulated, the size of the carbon black particles needs to be graded.

[0003] A carbon black granulation and grading device with the Chinese authorized announcement number CN218282599U is provided. By setting a discharge pipe with a valve, it is convenient to manually control the produced carbon black particles to enter the screen plate, and to perform graded storage with the cooperation of multiple screens. The vibration motor drives the screen plate to vibrate, so that the carbon black particles on the screen plate fall down in sequence, and the plug column and spring cooperate to make the screen plate swing up and down on the fixed seat, thereby guiding the carbon black particles to continue the grading operation.

[0004] There are still certain shortcomings in use. When classifying carbon black particles, since the screen is inclined, when a large number of carbon black particles fall, small-sized carbon black particles will pass through the subsequent second and third part screens, thereby reducing the accuracy of carbon black particle classification and limiting the practicality of the grading device.
