Description

Technical Field

[0001] The invention belongs to the technical field of gear oil production, and in particular relates to a method for preparing low-odor fully synthetic gear oil. Background Art

[0002] A Chinese patent with publication number CN117101464A discloses a preparation process for an environmentally friendly, low-odor industrial gear oil, comprising: a filtering mechanism and a stirring mechanism, wherein the stirring mechanism comprises a stirring drum, wherein a transmission shaft, a support plate 1 and a support plate 2 are arranged inside the stirring drum, an annular gear plate and a fixing plate are arranged on the outer wall of the transmission shaft, and a pair of rotating shafts and special-shaped gear plates are arranged on the inner sides of each pair of support plates 1 and 2; the materials used in the invention are environmentally friendly and can be completely degraded; when used as gear oil, no sludge will be generated, and the cleaning performance is excellent; the main reason is that the polyether base oil itself is an environmentally friendly material, which is easy to volatilize and has no residue after volatilization; in addition, the additives used have a low sulfur content, and the finished product has a light odor; the odor of the gear oil mainly comes from the active sulfur component in the extreme pressure anti-wear agent, which releases hydrogen sulfide gas, which is more obvious at high temperatures.

[0052] Embodiment 2

[0053] Based on Example 1, see Figure 2-Figure 6 shown.

[0054] The scraper mechanism 5 includes a support frame 501 fixedly connected to the mixing barrel 1, and a cam 502 fixedly connected to the mixing rod 32, a first scraper 503 is slidably connected to the support frame 501, one side of the top of the first scraper 503 is in contact with the top of the inner wall of the mixing barrel 1, a first reset component 504 is arranged between the first scraper 503 and the support frame 501, a first connecting frame 505 is fixedly connected to the first scraper 503, a first spring 506 is fixedly connected to the first connecting frame 505, a second connecting frame 507 is fixedly connected to the support frame 501, an inclined panel 508 is fixedly connected to the second connecting frame 507, a fixed rod 509 is fixedly connected to the front and back of the first scraper 503, two fixed rods 509 are rotatably connected to movable arms 510, a rope 511 is fixedly connected between the two movable arms 510, and the movable arm 510 is fixedly connected to the first spring 506. Since the raw materials are sticky, some of them will stick to the bottom of the piston plate 46. When mixing and stirring these raw materials, the motor 31 is turned on, and the motor 31 drives the stirring blade 33 to rotate through the stirring rod 32, so as to mix the raw materials. At the same time, the stirring rod 32 also drives the cam 502 to rotate, and then through the joint action of the cam 502 and the second spring 5044, the first scraper 503 is driven to reciprocate, so as to clean the bottom of the piston plate 46.

[0055] The first reset assembly 504 includes a first base plate 5041 fixedly connected to the support frame 501, and a second base plate 5042 fixedly connected to the first scraper 503, a straight rod 5043 is fixedly connected to the first base plate 5041, the straight rod 5043 is slidably connected to the second base plate 5042, and a second spring 5044 is fixedly connected between the first base plate 5041 and the second base plate 5042.

[0056] The movable arm 510 includes a first rod body 5101 rotatably connected to the fixed rod 509, a movable groove 5102 is opened at one end of the first rod body 5101, a second rod body 5103 is slidably connected in the movable groove 5102, a third spring 5104 is fixedly connected between the second rod body 5103 and the movable groove 5102, and the second rod body 5103 is fixedly connected to the rope 1 511. When the first scraper 503 approaches the piston plate 46, the first scraper 503 is first used to clean the piston plate 46. Secondly, the first rod 5101 and the inclined plate 508 are moved away from each other, so that the first rod 5101 is rotated downward on the fixed rod 509 under the action of the first spring 506. At the same time, the movable groove 5102 and the third spring 5104 are used to adjust the second rod 5103. In the process of the first spring 506 pulling the first rod 5101, the rope 511 on the second rod 5103 moves a maximum distance. When the first scraper 503 is away from the piston plate 46, the first rod 5101 and the inclined plate 508 are moved away from each other. They approach each other, and then, under the action of the first spring 506, the first rod body 5101 rotates upward on the fixed rod 509, and at the same time, the movable groove 5102 and the third spring 5104 adjust the second rod body 5103, so that in the process of the first spring 506 pulling the first rod body 5101, the movement distance of the rope 1 511 on the second rod body 5103 reaches the maximum; therefore, when the first scraper 503 reciprocates, not only the first scraper 503 is used to clean the piston plate 46, but also the rope 1 511 can be driven to reciprocate up and down, so as to clean the side of the first scraper 503 and improve the cleaning effect of the raw material.

[0057] The two edges of the first scraper plate 503 close to the cam 502 are both configured to be arcuate, and one side of the top of the inclined plate 508 is configured to be arcuate.

[0058] Embodiment 3

[0059] Based on Example 1, see Figure 4 and Figure 5 shown.

[0060] A vertical plate 6 is fixedly connected inside the mixing barrel 1, and a second scraper 8 is fixedly connected to the vertical plate 6 via a fourth spring 7. The second scraper 8 is slidably connected to a fixed rod 509, and an anti-slip block 9 is fixedly connected to one end of the fixed rod 509.

[0061] A rack 10 is fixedly connected to the bottom of the vertical plate 6, and a lifting screw 11 is rotatably connected to the second scraper 8. A gear 12 is fixedly connected to the bottom of the lifting screw 11, and the gear 12 is meshed with the rack 10. There are two racks 10 and two lifting screws 11, and both of the two lifting screws 11 are provided with a slide seat, and a rope 2 13 is provided between the two slide seats. When the first scraper 503 approaches the piston plate 46, since the anti-slip block 9 and the vertical plate 6 are in a fitted state, and the fourth spring 7 is in a stretched state, the second scraper 8 will move away from the piston plate 46 during the process of the first scraper 503 approaching the piston plate 46. When the second scraper 8 moves, the lifting screw 11 will rotate by utilizing the cooperation of the rack 10 and the gear 12, thereby driving the rope 2 13 to move along the surface of the second scraper 8. When the first scraper 503 moves away from the piston plate 46, the anti-slip block 9 and the fixed rod 509 act to drive the second scraper 8. When the second scraper 8 moves closer to the piston plate 46, the lifting screw 11 will rotate by utilizing the coordination of the rack 10 and the gear 12, thereby driving the second rope 13 to move along the surface of the second scraper 8. Therefore, through the above-mentioned movement coordination, the raw materials adhered to the top of the inner wall of the mixing barrel 1 can be cleaned. At the same time, during the movement of the second scraper 8, the lifting screw 11 is driven to rotate by utilizing the coordination of the rack 10 and the gear 12, so that the second rope 13 can be lifted and lowered, thereby cleaning the side of the second scraper 8 and improving the cleaning effect of the raw materials.

[0062] Embodiment 4

[0063] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-Figure 7 shown.

[0064] After adding raw materials to the feed pipe 2, the piston plate 46 is moved into the feed pipe 2 to clean the raw materials remaining in the feed pipe 2, thereby avoiding residual raw materials in the feed pipe 2. At the same time, the piston plate 46 is scraped by the movement of the first scraper 503 to clean the raw materials adhered to the piston plate 46.

[0065] The working principle of the present invention is as follows: the raw materials are poured into the mixing barrel 1 from the feed pipe 2 in sequence, and then the cover plate 44 is driven to descend by rotating the adjusting screw rod 43, and then the piston plate 46 is driven to descend by the connecting rod 45, so that the piston plate 46 enters the feed pipe 2, so that the piston plate 46 pushes the residual raw materials in the feed pipe 2 and cleans the inside of the feed pipe 2. At the same time, the bottom of the piston plate 46 is flush with the bottom of the feed pipe 2 and the top of the inner wall of the mixing barrel 1, and the cover plate 44 covers the port part outside the feed pipe 2. Since the raw materials are sticky, some of the raw materials will adhere to the bottom of the piston plate 46. When mixing and stirring these raw materials, the motor 31 is turned on, and then the motor 31 drives the stirring blade 33 to rotate through the stirring rod 32, so as to mix the raw materials. At the same time, the stirring rod 32 also drives the cam 502 to rotate, and then through the joint action of the cam 502 and the second spring 5044, the first scraper 503 is driven to reciprocate. When the first scraper 503 approaches the piston plate 46, the first scraper 503 is first used to clean the piston plate 46. Secondly, the first rod body 5101 and the inclined plate 508 are separated from each other, so that the first rod body 5101 is rotated downward on the fixed rod 509 under the action of the first spring 506, and at the same time, the movable groove 5102 and the third spring 5104 are used to adjust the second rod body 5103, so that the first spring 506 adjusts the first rod body 5 When the first scraper 503 moves away from the piston plate 46, the first rod 5101 and the inclined plate 508 approach each other, and then, under the action of the first spring 506, the first rod 5101 rotates upward on the fixed rod 509, and at the same time, the movable groove 5102 and the third spring 5104 are used to adjust the second rod 5103, so that during the process of the first spring 506 pulling the first rod 5101, the distance of the rope 511 on the second rod 5103 moves to the maximum; therefore, when the first scraper 503 reciprocates, not only the first scraper 503 is used to clean the piston plate 46, but also the rope 511 can be driven to reciprocate up and down, so as to clean the side of the first scraper 503 and improve the cleaning effect of the raw material.When the first scraper 503 approaches the piston plate 46, since the anti-slip block 9 and the vertical plate 6 are in a fitted state, and the fourth spring 7 is in a stretched state, the second scraper 8 will move away from the piston plate 46 during the process of the first scraper 503 approaching the piston plate 46. When the second scraper 8 moves, the lifting screw 11 will rotate by the cooperation of the rack 10 and the gear 12, thereby driving the rope 13 to move along the surface of the second scraper 8. When the first scraper 503 moves away from the piston plate 46, the anti-slip block 9 and the fixing rod 509 drive the second scraper 8 When the second scraper 8 moves closer to the piston plate 46, the lifting screw 11 will rotate by utilizing the coordination of the rack 10 and the gear 12, thereby driving the second rope 13 to move along the surface of the second scraper 8. Therefore, through the above-mentioned movement coordination, the raw materials adhered to the top of the inner wall of the mixing barrel 1 can be cleaned. At the same time, during the movement of the second scraper 8, the lifting screw 11 is driven to rotate by utilizing the coordination of the rack 10 and the gear 12, so that the second rope 13 can be lifted and lowered, thereby cleaning the side of the second scraper 8 and improving the cleaning effect of the raw materials.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
