AI Technical Summary
During the lubricant production process, additives with higher viscosity tend to adhere to the inner wall of the feed pipe, resulting in insufficient and uneven mixing.
A blending reactor was designed. By setting up a feed cylinder and multiple inclined auxiliary pipes, the continuous flushing of the oil inlet pipe and base oil ensures that the additives completely enter the reactor body and avoids residues. The flow rate of the base oil is controlled by a solenoid valve to enhance the flushing effect.
This effectively avoids additive residue on the inner wall of the feed cylinder, ensures uniform mixing of lubricating oil, and improves production efficiency.

[0028] A discharge pipe 12 is also arranged in the middle position of the bottom of the kettle body 1, a valve is also installed on the discharge pipe 12, after the blending and preparation of the lubricating oil are completed, the valve on the discharge pipe 12 can be opened, so that the lubricating oil is discharged from the discharge pipe 12.
[0029] The side upper part of the kettle body 1 is connected with a feeding cylinder 3 which is in communication with the inside thereof, the top of the feeding cylinder 3 is connected with an oil inlet pipe 31 which is in communication with the inside thereof, when used, the oil inlet pipe 31 is connected to the base oil supply pipeline, a first electromagnetic valve 311 is also installed on the feeding pipe, only when the first electromagnetic valve 311 is opened, the base oil enters the feeding cylinder 3, and then enters the inside of the kettle body 1 from the bottom.
[0030] The two sides of the feeding cylinder 3 are connected with the auxiliary pipes 4 which are in communication with the interior of the feeding cylinder 3, the auxiliary pipes 4 are connected with multiple auxiliary pipes 4, and the upper portions of the auxiliary pipes 4 are connected to the side edges of the feeding cylinder 3 in an upwardly inclined manner, and the third electromagnetic valve 41 is installed on the auxiliary pipes 4, in use, the auxiliary pipes 4 are connected to the feeding pipes of different additives, when the additives are added, the first electromagnetic valve 311 is ensured to be closed, the third electromagnetic valve 41 is opened, then the additives can be added into the feeding cylinder 3, then the third electromagnetic valve 41 is closed, and then the first electromagnetic valve 311 is opened, so that the remaining base oil which is not completely added is used to flush the inner wall of the feeding cylinder 3, so as to avoid the residual additives on the inner wall surface of the feeding cylinder 3.
[0031] In order to improve the flushing effect of the residual additives, the taper block 32 is fixed on the upper portion of the interior of the feeding cylinder 3 through the connecting rod 321, the upper portion of the taper block 32 is close to the inner wall of the oil inlet pipe 31, therefore, when the base oil enters the feeding cylinder 3, the base oil is guided by the taper block 32 to flow along the inner wall of the feeding cylinder 3 to the lower portion of the feeding cylinder 3, so as to ensure better flushing effect of the base oil on the inner wall of the feeding cylinder 3.
[0032] Since there is a part of the auxiliary pipes 4 between the third electromagnetic valve 41 and the feeding cylinder 3 which cannot be flushed by the base oil, the residual additives exist in the part of the auxiliary pipes 4, in order to make the residual additives in the auxiliary pipes 4 between the third electromagnetic valve 41 and the feeding cylinder 3 enter the kettle body 1 smoothly, the second embodiment is provided, which is different from the above only in that:
