Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a solvent deasphalting device for base oil production, which can adjust the rotation speed of the stirring shaft in real time through the change of the gravity of the mixture, increase the mixing rate, close the feeding in time, prevent the clogging during mixing, and increase the The linkage between the structures, the dredging hammer is used to continuously dredge the outlet to prevent blockage during discharge, and has the advantage of a high degree of automation, which solves the problem that the existing solvent deasphalting device cannot adjust the mixing in real time according to the weight change of the mixture speed, and the feed inlet cannot be closed in time, which makes the blockage more serious. When unloading, due to the high density of deoiled asphalt, it is inconvenient to discharge, and there are certain safety hazards.

The invention relates to the technical field of solvent deasphalting, and discloses a solvent deasphalting device for base oil production. The solvent deasphalting device comprises a mixing cylinder,an extraction tower is arranged on the left side of the mixing cylinder, a deasphalted oil outlet is formed in the top, and a heavy deasphalted oil outlet is formed in the upper part of the left sidewall of the extraction tower, adeoiledasphalt outlet is arranged below the left side wall of theextraction tower, and a material placing box is arranged at the right side of the top of themixing cylinder. According to the solvent deasphalting device for base oil production, a supporting plate slides downwards, so that a rack is driven to move downwards, a rotating rod is driven to rotate, a valveelement is driven to rotate, a through hole is closed, and more serious blocking caused by continuous feeding can be prevented; and the sealing performance of the spherical valve body is improved by arranging the sealing gasket, feeding is stopped in time through the gravity change of the mixture, the linkage between structures is improved, and the high automation degree is achieved.
Description
technical field [0001] The invention relates to the technical field of solvent deasphalting, in particular to a solvent deasphalting device for base oil production. Background technique [0002] Lubricating oil is generally composed of base oil and additives. The main production processes of lubricating oil base oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplementary refining. The solvent deasphalting process uses normal pressure and reduced pressure base oil as raw material, and uses propane, butane, pentane and other alkane solvents to extract and separate deasphalted oil from base oil according to the principle of similarity and compatibility. It is the most important raw material for the production of road asphalt and construction asphalt. [0003] In order to make the base oil and solvent mix better and improve the solvent usage rate, after the base oil and part of the solvent are mixed...
