Solvent mixing device used for petroleum asphalt production

Abstract

The invention discloses a solvent mixing device used for petroleum asphalt production. The solvent mixing device comprises a ventilation hole, a petroleum asphalt stirring and purifying device, a solvent tank, a solvent pipeline, a vacuum residue input pipe, a control panel, a transmission wire, a supporting column, a guide pulley, a handle and an open-close door, wherein the ventilation hole is embedded in the upper end of the right surface of the petroleum asphalt stirring and purifying device, the solvent tank fits the center of the upper surface of the petroleum asphalt stirring and purifying device, the upper end of the solvent pipeline is connected with the upper end of the solvent tank by virtue of glue, and the vacuum residue input pipe is welded at the left end of the upper surface of the petroleum asphalt stirring and purifying device. The solvent mixing device disclosed by the invention has the advantages that the petroleum asphalt stirring and purifying device is arranged,vacuum residues and a solvent are completely mixed during stirring, dissolution rate is improved, asphalt is completely separated, then moisture in the asphalt is removed, the purity of the asphalt isfurther improved, and the finished product processing and application of asphalt in a later period are facilitated.

Description

technical field [0001] The invention relates to a solvent mixing device for producing petroleum asphalt, which belongs to the field of petroleum asphalt. Background technique [0002] Petroleum asphalt is a product of crude oil processing. It is a black or dark brown viscous liquid, semi-solid or solid at room temperature. It mainly contains hydrocarbons and non-hydrocarbon derivatives soluble in trichlorethylene. Its properties And the composition varies with the source of crude oil and the production method. When producing asphalt with the current technical public equipment, due to the incomplete mixing of the solvent and the vacuum residue, it is difficult to separate the asphalt, which affects the separation rate of the asphalt, and the separation rate of the asphalt is The asphalt is not high in purity and contains moisture, which affects the processing of asphalt products in the later stage and is inconvenient to use. Contents of the invention [0003] Aiming at the...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a solvent mixing device for petroleum asphalt production, to solve the problem of separation of asphalt due to incomplete mixing of solvent and vacuum residue when producing asphalt with common equipment in the current technology. Difficult, affecting the separation rate of asphalt, and the asphalt after separation is not high in purity, contains moisture, affects the processing of finished asphalt products in the later stage, and is inconvenient to use
