[0021] The present invention will be further described below with reference to the drawings: As Figure 1 —Figure 4 As shown in the figure, this embodiment provides a fully mixed lubricating oil blending device, which includes a stirring kettle body 1, a suspended scraping device 2, a suspended stirring device 3, a suspended guiding rod 4, a stirring gas injection device 5, a cleaning gas injection device 6, a rotating supporting device 7 and a rotating support bracket 8. The rotating support bracket 8 is installed inside the stirring kettle body 1, and the suspended guiding rod 4 is suspended inside the stirring kettle body 1. The suspended scraping device 2 slides up and down along the inner side wall of the stirring kettle body 1 to scrape off the residual oil. The suspended stirring device 3 is slidably installed on the suspended guiding rod 4 to realize lifting and stirring. A suspended chamber 33 with an opening downward is formed between the suspended stirring device 3 and the suspended guiding rod 4, so that the suspended stirring device 3 obtains buoyancy. After the suspended chamber 33 is injected with gas, the suspended stirring device 3 floats upward, and stirring is realized during the upward floating process. A stirring fan surface 34 is provided outside the suspended stirring device 3. The stirring gas injection device 5 is located directly below the corresponding suspended stirring device 3, and the cleaning gas injection device 6 is located directly below the corresponding stirring fan surface 34. After stirring, the cleaning gas injection device 6 blows the stirring fan surface 34 to make the suspended stirring device 3 rotate at a high speed. The rotating supporting device 7 is rotatably installed on the rotating support bracket 8. When the suspended stirring device 3 is installed and descends to the lowest point, it presses on the rotating supporting device 7 to provide support for the rotary discharging of the suspended stirring device 3, realizing energy-saving blending of lubricating oil, preventing cross-contamination of lubricating oil, and ensuring blending accuracy.

[0022] Specifically, the bottom of the stirring kettle body 1 is arc-shaped, which is convenient for draining the lubricating oil after blending.

[0023] Specifically, the suspended scraping device 2 includes a scraping ring. An opening for the suspended guiding rod 4 to pass through is provided on the suspended scraping device 2. There are several exhaust grooves 21 on the lower side of the opening. The scraping ring is located around the suspended scraping device 2. The middle of the suspended scraping device 2 is high, and the periphery of the suspended scraping device 2 is low, which is convenient for the scraping ring to float up after the stirring gas injection device 5 injects gas, so that the suspended scraping device 2 can float up when the stirring gas injection device 5 injects gas, providing a stroke for the lifting action of the suspended stirring device 3. Also, because the middle of the suspended scraping device 2 is high and the periphery of the suspended scraping device 2 is low, the oil on the suspended scraping device 2 can flow towards the side wall of the stirring kettle body 1 under the action of gravity after blending. At the same time, the lubricating oil on the side wall of the stirring kettle body 1 is scraped down by the scraping ring around the suspended scraping device 2. On the other hand, because the middle of the suspended scraping device 2 is high and the periphery of the suspended scraping device 2 is low, it is convenient for the gas to be discharged from the opening position for the suspended guiding rod 4 to pass through at the exhaust groove 21 position after blending, and it is convenient for the suspended scraping device 2 to fall after blending.

[0024] 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. An exhaust passage 311 is provided at the upper end of the rotating stirring barrel 31. The end of the exhaust passage 311 slides along the suspension guide rod 4. When the suspension stirring device 3 rises to the upper limit position, the exhaust passage 311 disengages from the suspension guide rod 4, so that the gas in the suspension chamber 33 is discharged from the exhaust passage 311, and then the suspension stirring device 3 loses buoyancy and rapidly descends. After the exhaust passage 311 is blocked by the suspension guide rod 4 again, the suspension chamber 33 stores gas again and the rotating stirring barrel 31 rises again, realizing reciprocating stirring.

[0025] Specifically, the top of the suspension guide rod 4 is suspended at the top of the stirring kettle body 1 by a suspension wire rope 9. Since the diameter of the suspension wire rope 9 is smaller than the diameter of the suspension guide rod 4, it is convenient for the exhaust passage 311 to exhaust.

[0026] 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 passage 311 rises to the top of the suspension guide rod 4. At this time, the rotating stirring barrel 31 rises to the top of the liquid level, and the exhaust passage 311 disengages from the suspension guide rod 4, so that the exhaust passage 311 is opened, and the air is discharged from the exhaust passage 311. The rotating stirring barrel 31 loses buoyancy and rapidly descends along the suspension guide rod 4. During the downward movement of the rotating stirring barrel 31, the suspension chamber 33 catches the air discharged from the stirring gas injection device 5, so that the buoyancy of the rotating stirring barrel 31 increases until the rotating stirring barrel 31 rises again, realizing the reciprocating up and down movement stirring of the rotating stirring barrel 31.

[0027] Specifically, the stirring gas injection device 5 includes a stirring gas injection pipe 51 and a stirring gas injection collecting hopper 52. The stirring gas injection collecting hopper 52 is installed at the bottom of the rotating support bracket 8 with the opening facing downward. The rotating support bracket 8 is provided with an injection hole 81 at the position of the stirring gas injection collecting hopper 52. The stirring gas injection pipe 51 is located at the lower end of the stirring gas injection collecting hopper 52, which is convenient for the gas to fill the suspension stirring device 3 and make the suspension stirring device 3 float.

[0028] Specifically, the cleaning gas injection device 6 includes a plurality of cleaning gas injection pipes, and each cleaning gas injection pipe points to the stirring fan surface 34. After the mixing is completed, the rotating stirring barrel 31 falls, and the cleaning gas injection pipe blows the stirring fan surface 34 to make the rotating stirring barrel 31 rotate, thereby realizing the shaking off and separation of the lubricating oil. In actual production, the topmost point of the cleaning gas injection device 6 can be made higher than the lowest end of the suspension guide rod 4, thereby restricting the swinging amplitude of the suspension guide rod 4 and facilitating the rotating stirring barrel 31 to press on the rotating support device 7.

[0029] Specifically, the rotating support device 7 includes a rotating support plate 71, and a rotating support top cone 72 is provided at the bottom of the rotating support plate 71 to reduce the rotational friction.

[0030] It should be noted that an anti-tipping block 711 is provided on the side of the rotating support plate 71 and presses on the rotating support bracket 8. The anti-tipping block 711 is used to maintain the posture of the rotating support plate 71 when the rotating stirring barrel 31 does not press on the rotating support plate 71. When the level of the lubricating oil discharged after being well-mixed decreases, after the rotating stirring barrel 31 presses on the rotating support plate 71, the cleaning air injection device 6 blows to drive the stirring fan surface 34. The rotating stirring barrel 31 can be constrained by the suspension guide rod 4, so that the rotating stirring barrel 31 and the rotating support plate 71 rotate synchronously, and the lubricating oil on the rotating stirring barrel 31 is thrown off, reducing waste.

[0031] A lubricating oil blending process uses a fully mixed lubricating oil blending device, including the following steps: S1: Inject various raw oils into the stirring kettle body 1, and the stirring air injection device 5 injects air, so that the suspension stirring device 3 stirs while rising; S2: After the blending is completed, the stirring air injection device 5 stops injecting air, and discharges the blended lubricating oil; S3: The suspension scraping device 2 descends to scrape the residual lubricating oil on the inner side of the stirring kettle body 1; S4: The cleaning air injection device 6 blows air directly below the corresponding stirring fan surface 34, so that the cleaning air injection device 6 rotates synchronously with the rotating support device 7 to throw off the excess lubricating oil.
