[0036] The present invention will be further described below in conjunction with the accompanying drawings:

[0037] like Figure 1 — Figure 4 As shown, this embodiment provides a fully mixed lubricating oil blending device, including a mixing kettle body 1, a suspension scraper device 2, a suspension stirring device 3, a suspension guide rod 4, a stirring and air injection device 5, a cleaning and air injection device 6, a rotating support device 7 and a rotating support bracket 8. The rotating support bracket 8 is installed in the mixing kettle body 1, and the suspension guide rod 4 is suspended in the mixing kettle body 1. The suspension scraper device 2 rises and slides along the inner wall of the mixing kettle body 1 to scrape off the residual oil. The suspension stirring device 3 is slidably installed on the suspension guide rod 4 to achieve lifting and stirring. A suspension chamber 33 with an opening downward is formed between the suspension stirring device 3 and the suspension guide rod 4, so that the suspension stirring device 3 obtains buoyancy. After the suspension chamber 33 is injected with air, the suspension stirring device 3 is able to float, and stirring is achieved during the floating process. A stirring fan 34 is provided on the outside of the suspension stirring device 3, and the stirring and air injection device 5 is located directly below the corresponding suspension stirring device 3. The cleaning and air injection device 6 is located directly below the corresponding stirring fan 34. After the stirring is completed, the cleaning and air injection device 6 blows the stirring fan 34 to make the suspension stirring device 3 rotate at high speed. The rotating support device 7 is rotatably installed on the rotating support frame 8. The suspension stirring device 3 is installed on the rotating support device 7 when it drops to the lowest point, thereby providing support for the rotation and material throwing of the suspension stirring device 3, realizing energy-saving blending of lubricating oil, preventing cross contamination of lubricating oil, and ensuring blending accuracy.

[0038] Specifically, the bottom of the stirring tank body 1 is arc-shaped, which is convenient for draining the lubricating oil after the blending is completed.

[0039] Specifically, the suspension scraper device 2 includes a scraper ring. The suspension scraper device 2 is provided with an opening for the suspension guide rod 4 to pass through. The lower side of the opening is provided with a plurality of exhaust grooves 21. The scraper ring is located around the suspension scraper device 2. The middle part of the suspension scraper device 2 is high, and the surrounding parts of the suspension scraper device 2 are low, so that the scraper ring can float after the stirring and gas injection device 5 injects gas, so that the suspension scraper device 2 can float when the stirring and gas injection device 5 injects gas, providing a stroke for the lifting action of the suspension stirring device 3. Since the middle part of the suspension scraper device 2 is high, The suspension scraper device 2 is low on all sides, so that after the blending is completed, the oil on the suspension scraper device 2 can flow to the side wall of the mixing kettle body 1 under the action of gravity. At the same time, the lubricating oil on the side wall of the mixing kettle body 1 is scraped downward by the scraper rings around the suspension scraper device 2. On the other hand, since the middle part of the suspension scraper device 2 is high and the surrounding areas of the suspension scraper device 2 are low, it is convenient for the gas to be discharged from the opening position of the exhaust groove 21 for the suspension guide rod 4 to pass through after the blending is completed, which facilitates the suspension scraper device 2 to fall after the blending is completed.

[0040] Specifically, the suspension stirring device 3 includes a rotating stirring barrel 31 and stirring blades 32. The stirring blades 32 are installed on the outer periphery of the rotating stirring barrel 31 to form a stirring fan surface 34. The upper end of the rotating stirring barrel 31 is provided with an exhaust channel 311. The end of the exhaust channel 311 slides along the suspension guide rod 4. When the suspension stirring device 3 rises to the upper limit position, the exhaust channel 311 disengages from the suspension guide rod 4, so that the gas in the suspension chamber 33 is discharged from the exhaust channel 311, and the suspension stirring device 3 loses buoyancy and rapidly drops. After the exhaust channel 311 is blocked by the suspension guide rod 4 again, the suspension chamber 33 stores air again, causing the rotating stirring barrel 31 to rise again, thereby realizing reciprocating stirring.

[0041] Specifically, the top of the suspension guide rod 4 is suspended on the top of the mixing tank body 1 through the suspension wire rope 9. Since the diameter of the suspension wire rope 9 is smaller than the diameter of the suspension guide rod 4, exhaust through the exhaust channel 311 is convenient.

[0042] After the suspension chamber 33 in the rotating stirring barrel 31 is filled with air, the rotating stirring barrel 31 will accelerate upward along the suspension guide rod 4 until the exhaust channel 311 rises to the top of the suspension guide rod 4, the rotating stirring barrel 31 rises to the top of the liquid level, the exhaust channel 311 is separated from the suspension guide rod 4, so that the exhaust channel 311 is opened, and the air is discharged from the exhaust channel 311. The rotating stirring barrel 31 loses buoyancy and quickly descends along the suspension guide rod 4. During the downward process of the rotating stirring barrel 31, the suspension chamber 33 catches the air discharged from the stirring and air injection device 5, thereby increasing the buoyancy of the rotating stirring barrel 31 until the rotating stirring barrel 31 rises again, thereby realizing the reciprocating up and down motion of the rotating stirring barrel 31 for stirring.

[0043] Specifically, the stirring and gas injection device 5 includes a stirring and gas injection pipe 51 and a stirring and gas injection collecting bucket 52. The stirring and gas injection collecting bucket 52 is installed with its opening downward at the bottom of the rotating support bracket 8. The rotating support bracket 8 is provided with a gas injection hole 81 at the position of the stirring and gas injection collecting bucket 52. The stirring and gas injection pipe 51 is located at the lower end of the stirring and gas injection collecting bucket 52, so that the gas fills the suspended stirring device 3 and causes the suspended stirring device 3 to float.

[0044] Specifically, the cleaning air injection device 6 includes several cleaning air injection pipes, each of which points to the stirring fan 34. After the blending is completed, the rotating stirring barrel 31 falls, and the cleaning air injection pipe blows the stirring fan 34 to make the rotating stirring barrel 31 rotate, thereby realizing the swinging and separation of the lubricating oil. In actual production, the top of the cleaning air injection device 6 can be made higher than the lowest end of the suspended guide rod 4, thereby limiting the swing amplitude of the suspended guide rod 4, making it easier for the rotating stirring barrel 31 to press on the rotating support device 7.

[0045] Specifically, the rotary support device 7 includes a rotary support plate 71 , and a rotary support top cone 72 is provided at the bottom of the rotary support plate 71 to reduce rotational friction.

[0046] It is worth noting that an anti-tilt block 711 is provided on the side of the rotating support plate 71, which is pressed on the rotating support bracket 8. The anti-tilt block 711 is used to maintain the posture of the rotating support plate 71 when the rotating mixing barrel 31 is not pressed on the rotating support plate 71, so that when the discharge level of the blended lubricating oil is lowered, the rotating mixing barrel 31 is pressed on the rotating support plate 71, and the cleaning air injection device 6 blows the mixing fan 34. The rotating mixing barrel 31 can be constrained by the suspended guide rod 4, so that the rotating mixing barrel 31 and the rotating support plate 71 rotate synchronously, and the lubricating oil on the rotating mixing barrel 31 is thrown off to reduce waste.

[0047] The lubricant blending process uses a fully mixed lubricant blending device and includes the following steps:

[0048] S1: The raw oils are injected into the stirring tank body 1, and the stirring and gas injection device 5 injects gas, so that the suspension stirring device 3 stirs while rising;

[0049] S2: After the blending is completed, the stirring and gas injection device 5 stops injecting gas and discharges the blended lubricating oil;

[0050] S3: The suspended scraper device 2 falls to scrape off the residual lubricating oil inside the stirring tank body 1;

[0051] S4: The cleaning air injection device 6 blows air just below the corresponding stirring fan 34, so that the cleaning air injection device 6 and the rotating support device 7 rotate synchronously to throw off the excess lubricating oil.
