Embodiment Construction

[0024] Such as figure 1 and figure 2 As shown, the carbon black powder removal device is mainly composed of an air-flow conveying device such as a blower 3 and a powder remover fluidized bed 2, wherein a horizontal sieve plate 5 is arranged on the powder remover fluidized bed, and the sieve plate is covered with presses. The same direction as the movement direction of carbon black particles obliquely penetrates the horizontal sieve plate, that is, the upper end is biased towards the discharge end of the fluidized bed of the powder remover, and the lower end is biased towards the air hole at the feed end of the fluidized bed of the powder remover, and the bottom of the fluidized bed is set Four air inlets 6 are connected to a blower 3 through an air delivery pipe 7 with an air pressure regulating valve and an air pressure gauge. Each of the above air inlets and the horizontal sieve plate form a winnowing cooling section. Also, the top of the above-mentioned fluidized bed comm...

Abstract

The invention relates to a carbon black powder removing method and a device, belonging to the technical field of carbon black manufacturing. The carbon black powder removing method is used for removing the carbon black powder in carbon black pellets; the dried carbon black pellets containing powders are added to the feed end of a fluidized bed of a powder remover; the carbon black pellets run through the fluidized bed under the blowing of the air entering aslant below the fluidized bed and are discharged through the discharge end of the fluidized bed; at the same time, the powders are discharged through the top of the fluidized bed. The invention adopts the method of winnowing products under suspension state, has the advantages of high powder removing efficiency, low product damage rate, cooling product, meeting black storage requirements, improving packaging conditions, simple and efficient technology, and saving resources; besides, the adopted devices has simple and reasonable structure and easy production and maintenance, can effectively improve winnowing and cooling efficiency and realize reasonable energy utilization. The invention can be widely applied to the technical field of carbon black pellet processing and can effectively improve production efficiency and product quality.

Description

technical field [0001] The invention specifically relates to a carbon black powder removal method and device in the technical field of carbon black production. Background technique [0002] Carbon black is an important raw material for the rubber industry. With the development of the rubber industry, higher and higher requirements are put forward for carbon black as the main reinforcing agent for rubber. Generally, carbon black granule products contain a certain amount of fine powder. Excessive fine powder content will not only cause pollution to product transportation, carbon black packaging environment, and rubber mixing environment, but also affect carbon black packaging standards (packaging volume caused by changes in apparent density) change), and will cause harm to the air conveying system of the rubber industry, and at the same time, an excessively high fine powder content will affect the dispersion of carbon black in the rubber compound and reduce the mechanical and...
