Online oxidized carbon black treatment device

Abstract

The invention belongs to the technical field of carbon black production, and provides an online oxidized carbon black treatment device. The device comprises a shell, a feeding assembly and a wall scraping assembly; a reaction chamber is arranged in the shell, and an air inlet chamber is arranged on one side of the shell; the feeding assembly is arranged on one side of the shell, and the feeding assembly is used for transferring carbon black into the reaction chamber; and the wall scraping assembly is arranged in the reaction chamber, and the wall scraping assembly is used for scraping off carbon black attached to the inner wall of the reaction chamber. When the online oxidized carbon black treatment device is used, the wall scraping assembly can be started, carbon black powder on the side wall can be scraped off through operation of a lifting device, a linkage device can control the length of the wall scraping assembly, the situation that the wall scraping assembly is still in contact with the side wall when ascending, and consequently the powder is accumulated on the wall scraping assembly is avoided, and meanwhile a rotating device can drive the wall scraping assembly to rotate once after the wall scraping assembly finishes ascending and descending once, so that the comprehensive scraping effect is achieved, the wall scraping effect is good, and carbon black powder is prevented from being excessively oxidized.

Description

technical field [0001] The invention belongs to the technical field of carbon black production, and in particular relates to an online oxidation carbon black treatment device. Background technique [0002] Carbon black oxidation treatment is a process in which carbon black particles are modified by oxidation with an oxidizing agent. There are gas-phase oxidation and liquid-phase oxidation. The oxidants for gas phase oxidation include molecular oxygen, atomic oxygen, ozone, dry air or wet air, etc., and the oxidants for liquid phase oxidation include nitric acid, potassium permanganate, and ozone aqueous solution. Carbon black oxidation treatment can change the surface area, porosity and conductivity of carbon black. [0003] The way of carbon black oxidation treatment is mostly to pass carbon black into the reaction chamber through the feed assembly, and then pass oxygen through the air inlet chamber to make it fully react with carbon black in the reaction chamber, but dur...
