[0002] In the production process of lubricating oil, additives need to be added to the lubricating oil for blending. A search revealed a patent with application number 202021020231.6, which discloses a lubricating oil blending device for lubricating oil production. This device includes a tank, with a motor mounted at the top. The output shaft of the motor is fixedly connected to a rotating shaft, the bottom end of which passes through the tank and extends into its inner cavity. An oil outlet pipe is located at the bottom center of the tank, and a disassembly mechanism is provided at the bottom end of the oil outlet pipe. While this prior art facilitates disassembly and cleaning, the following problems still exist in practical use: When blending lubricating oil, the stirring rod driven by the motor is used to stir the lubricating oil. The stirring range is small and there are large dead zones. When adding additives, they are poured directly into the tank. The additives are concentrated in one area of ​​the tank, which makes it impossible for the lubricating oil and additives to mix evenly and thus results in poor blending effect.

A valve is installed on the discharge pipe 19, and a feed port is opened at the top of the mixing tank 4. The lubricating oil to be mixed can be poured into the mixing tank 4 through the feed port, and the lubricating oil after mixing can be discharged through the discharge pipe 19. Specifically, the lifting stirring mechanism includes a drive assembly, a material adding assembly, four electric push rods 5 that are fixedly installed on the outer walls of the four corners of the top of the top seat 3, a lifting cover 6 that is fixedly connected to the telescopic ends of the four electric push rods 5, a rotating tube 7 that is rotatably installed at the center of the lifting cover 6, and stirring blades 8 that are fixedly connected to the bottom of the rotating tube 7.

Furthermore, the material addition assembly includes a support plate 14 fixedly connected to the side wall of the fixed cover 9, a rotary joint 17, three nozzles 13 fixedly connected to the lower part of the rotary tube 7 and arranged in a ring, and an additive storage tank 15 and a micro delivery pump 16 fixedly connected to the top outer wall of the support plate 14 in sequence. Each of the three nozzles 13 is equipped with a one-way valve. The top of the additive storage tank 15 is provided with a filling pipe, and a sealing cap is threaded on the filling pipe. The required additive can be added by opening the sealing cap. Furthermore, the suction end of the micro-pump 16 is connected to the additive storage tank 15 through a pipe, and the delivery end of the micro-pump 16 is sealed and fixedly connected to the fixed part of the rotary joint 17 through the delivery pipe. The top end of the rotary pipe 7 passes through the top of the fixed cover 9, and the rotating part of the rotary joint 17 is sealed and fixedly connected to the top end of the rotary pipe 7. Through the transfer effect of the rotary joint 17, the normal material supply of the micro-pump 16 in the rotating state can be guaranteed. Furthermore, a PLC controller 18 is fixedly installed on the side wall of the top seat 3. All four electric push rods 5 are electrically connected to the PLC controller 18. The PLC controller 18 can control the four electric push rods 5 to work synchronously.

In this way, the PLC controller 18 can control the normal operation of the micro conveying pump 16 and the drive motor 10 in the lifting motion state. The working principle of this embodiment is as follows: First, the drive motor 10 controls the rotation of the active bevel gear 11, and then the driven bevel gear 12, which meshes with the active bevel gear 11, drives the stirring blade 8 and the three nozzles 13 on the rotating tube 7 to rotate together. Second, the additive stored in the additive storage tank 15 is extracted by the micro-pump 16 and transported to the rotating tube 7 through the rotary joint 17 via the delivery pipe. Then, the additive is sprayed out by the three nozzles 13 with one-way valves and mixed with the lubricating oil for blending. Finally, the PLC controller 18 controls the four electric push rods 5 to work synchronously so that the lifting cover 6 can move up and down, thereby enabling the rotating stirring blade 8 to move up and down in the mixing tank 4, effectively expanding the stirring range and reducing the stirring dead zone. Furthermore, the three rotating nozzles 13 move up and down along the mixing tank 4, allowing the required additive to be evenly diffused to different areas inside the mixing tank 4. In this way, the lubricating oil and the additive can be fully and evenly mixed, thereby improving the blending effect.

The working principle of this embodiment is as follows: By placing the receiving container 20 at the center of the base 1, it will squeeze the two V-shaped locking blocks 25 and cause the two sliding blocks 23 to slide away from each other on the linear guide rail 21. At the same time, the spring 24 will be stretched. After the receiving container 20 is placed, under the elastic reset of the spring 24, the two V-shaped locking blocks 25 will move closer together to reset. Then, the two V-shaped locking blocks 25 will clamp the receiving container 20 to ensure the stability of the receiving process. Finally, by opening the valve, the mixed lubricating oil is discharged from the discharge pipe 19 and collected by the receiving container 20.
