Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, and in particular to a mixing tank for multi-stage lubricating oil mixing. Background Technology

[0002] Multi-grade lubricating oil is a type of lubricating oil that can maintain stable viscosity and good lubrication performance over a wide temperature range. The mixing tank for multi-grade lubricating oil is a key piece of equipment used in the production process to uniformly mix base oils and additives of different viscosities and properties. It is widely used in automotive engines, industrial equipment and other fields.

[0003] Existing multi-stage lubricating oil mixing tanks have a relatively simple structure, slow additive dispersion speed, difficulty in quickly integrating into base oil, time-consuming mixing, low efficiency, and difficulty in fully mixing base oils of different viscosities due to large differences in fluidity, resulting in mixing dead zones, uneven mixing, and affecting the performance of lubricating oil and production efficiency.

[0004] Therefore, to address the problems of uneven mixing and low production efficiency in existing multi-stage lubricating oil mixing reactors, a multi-stage lubricating oil mixing reactor can be designed. Utility Model Content

The metering pump 4 precisely controls the volume to improve the quality of the lubricating oil. Steam is introduced into the jacket layer 2 to exchange heat evenly with the mixing tank 1 and increase fluidity. The liquid addition pipe 6 drives the liquid outlet pipe 7 to rotate. Additives are added to the liquid addition pipe 6 and sprayed evenly through the liquid outlet pipe 7 to increase the spraying range. The spiral blades 8 rotate in the opposite direction to push the material at the lower end upward. The U-shaped connecting frame 9 drives the stirring blades 10 and the rubber scraper 11 to rotate synchronously.

The filling pipe 6 and the outlet pipes 7 are connected. The additive flows into the outlet pipes 7 through the filling pipe 6 and is sprayed evenly inside the material, increasing the spraying range and improving the dispersion effect of the additive.

The rotating motor 17 drives the gear 18 to rotate, and the gear 18 drives the gear ring 19 and the liquid addition pipe 6 to rotate. The volume control valve 20 controls the amount of additive entering the liquid addition pipe 6 and sprays it evenly through the liquid outlet pipe 7. The stirring motor 21 drives the spiral blade 8 to rotate in the opposite direction, pushing the material at the bottom upward.

The rubber scraper 11 scrapes off the material adhering to the inner wall, and the mixed lubricating oil is discharged from the oil outlet pipe 15.

[0027] Through the above steps, the additive is evenly sprayed out through the liquid outlet pipe 7, increasing the spraying range. The spiral blade 8 rotates in the opposite direction to push the material at the lower end upward, forming a bidirectional convection stirring with the stirring blade 10, so that the material forms an efficient up-and-down circulation, improving the mixing uniformity and stirring efficiency, and improving the quality of lubricating oil, thereby solving the problems of uneven mixing and low production efficiency in existing multi-stage lubricating oil mixing tanks.
