Waste tire pyrolysis carbon black magnetic separation device based on environmental protection

Abstract

The invention discloses a waste tire pyrolysis carbon black magnetic separation device based on environmental protection, and relates to the technical field of carbon black magnetic separation, the waste tire pyrolysis carbon black magnetic separation device comprises a case, the top of the case is provided with a storage bin, the inner top of the case is provided with a conduction magnetic attraction mechanism, through the arrangement of the storage bin, powder of waste tire pyrolysis carbon black can be effectively contained, and the waste tire pyrolysis carbon black can be effectively separated. According to the invention, the carbon black powder is placed in the feeding pipe and is sealed and covered by the movable partition plate, then the carbon black powder is weighed by the measuring hopper under the action of gravity, and the connecting motor drives the measuring hopper to rotate, so that the measuring hopper is turned over, and the weighed carbon black powder inside the measuring hopper is guided into the discharging pipe; meanwhile, the carbon black powder is conducted to a conveying belt of a conduction driving mechanism through a discharging pipe, subsequent magnetic attraction screening and conduction are conducted on the carbon black powder, then the device can conduct quantitative feeding, and the situation that the carbon black powder is accumulated, the using effect of subsequent magnetic attraction operation is affected, and operation blockage of the device is caused is avoided; and the use convenience and usability of the device are effectively improved.

Description

technical field [0001] The invention relates to the technical field of carbon black magnetic separation, in particular to an environmental protection-based waste tire pyrolysis carbon black magnetic separation device. Background technique [0002] Carbon black, also known as carbon black, is an amorphous carbon, a light, loose and extremely fine black powder with a very large surface area ranging from 10 to 3000m2 / g. , fuel oil, etc.) products obtained by incomplete combustion or thermal decomposition under the condition of insufficient air. The one made of natural gas is called "gas black", the one made of oil is called "lamp black", and the one made of acetylene is called "acetylene black"; in addition, there are "slot black" and "furnace black", according to the properties of carbon black There are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black", etc., which can be used as black dyes for the manufacture of Chinese inks, inks, paints, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, waste tire pyrolysis carbon black is different from the traditional carbon black production method. Waste tires are produced by pyrolysis technology. There are more waste steel wires and iron filings in the carbon black that need to be selected. The magnetic separation process needs to separate the carbon black The powder is completely separated from the steel wire and iron filings, and the steel wire and iron filings are discharged smoothly. However, when the existing waste tire pyrolysis carbon black magnetic separation device fills the feed port, it is inconvenient to quantitatively feed the material, and the carbon black will accumulate on the conveyor belt. At present, there is no way to evenly spread the imported carbon black, so that the metal in the accumulated carbon black cannot be fully magnetically separated, which leads to a large metal content in the carbon black, which reduces its magnetic separation effect, and at the same time the carbon black powder During the transmission process, it is easy to adhere to the conveyor belt, which will affect the smoothness of its magnetic separation operation and transmission operation in the subsequent long-term application and accumulation, and will not be cleaned up, resulting in waste of carbon black powder and environmental protection. Poor, for this reason, a kind of waste tire pyrolysis carbon black magnetic separation device based on environmental protection is proposed to solve the above problems
