Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to a lubricating oil additive anti-sedimentation mixing tank. Background Technology

[0002] Lubricating oil additives are one or more compounds added to lubricants to give them new properties or improve existing properties. Additives are mainly classified by function into antioxidants, anti-wear agents, friction modifiers (also known as oiliness agents), extreme pressure additives, detergents, dispersants, foam inhibitors, corrosion and rust inhibitors, pour point improvers, and viscosity index enhancers.

[0003] The utility model patent with authorization announcement number CN217119998U discloses a lubricating oil additive uniform mixing device. By setting a first stirrer and a second stirrer in the mixing tank, and using a first motor and a second motor to drive the stirring rod and stirring frame to stir the mixture in opposite directions, the lubricating oil and additives can be fully contacted and mixed more evenly. This can also accelerate the mixing efficiency of the lubricating oil additives and improve product quality. By setting several baffles vertically on the inner wall of the mixing tank and setting several electric heating devices on the lower part of the side wall of the mixing tank, the lubricating oil and additives can be mixed more evenly and the mixing efficiency can be higher. However, the following shortcomings still exist: under long-term and frequent use or storage in the mixing tank, due to the large variety of additives, chemical reactions may occur, which may cause some additives to precipitate. This can lead to some additive raw materials clumping and accumulating at the bottom of the mixing tank, and may even gradually block the discharge port, affecting the normal discharge of the discharge port and reducing working efficiency. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a lubricating oil additive anti-sedimentation mixing tank to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: A lubricating oil additive anti-settling mixing tank includes a tank body, a main infusion pipe on one side of the tank body, a plurality of branch infusion pipes connected to the main infusion pipe, a discharge port at the lower end of the tank body, a support leg at the lower end of the tank body, a stirring assembly inside the tank body, an anti-settling assembly at the lower end of the stirring assembly, the anti-settling assembly including a synchronous shaft, connecting plates on both sides of the synchronous shaft, a scraper at the lower end of the connecting plates, the outer wall of the scraper fitting against the inner wall of the tank body, a rectangular through groove on the scraper, a plurality of rotating shafts rotatably connected within the rectangular through groove, and a crushing roller fixedly sleeved on the rotating shaft.

[0006] Preferably, the stirring assembly includes a drive motor mounted on the upper end of the tank, the output end of the drive motor passing through the tank and connected to a stirring shaft, and stirring rods provided on both sides of the stirring shaft.

[0007] Preferably, the inner wall of the tank is vertically welded with several strip-shaped baffles.

[0008] Preferably, the discharge port is equipped with a filter screen plate, and the side wall of the scraper plate is provided with a scraper plate, the lower surface of the scraper plate abutting against the upper surface of the filter screen plate.

[0009] Preferably, the cross-sectional shape of the scraper is a right trapezoid with the sharp end facing upwards.

[0010] This utility model has the following beneficial effects:

[0011] 1. This lubricating oil additive anti-sedimentation mixing tank delivers lubricating oil into the tank through the main infusion pipe, and simultaneously delivers various additives that improve the performance of the lubricating oil into the tank through the branch infusion pipes. The stirring shaft and stirring rod of the stirring assembly ensure full contact between the lubricating oil and the additives, resulting in more uniform mixing and accelerating the mixing efficiency of the lubricating oil additives, thus improving product quality. The anti-sedimentation component prevents some additives from settling due to long-term frequent use or storage of the mixing tank. It promptly scrapes off lumpy sediment from the inner side wall and bottom of the tank, ensuring that the additive raw materials do not clump together and accumulate at the bottom of the mixing tank, thus ensuring normal material discharge from the outlet and improving work efficiency.

[0012] 2. When using the anti-sedimentation component, the synchronous shaft rotates synchronously with the stirring component. The synchronous shaft drives the connecting plate and the scraper to rotate synchronously. When the scraper rotates clockwise to scrape off the blocky sediment material on the inner side wall and bottom of the tank, the blocky sediment material is driven to flip upward and collide with the crushing roller under the action of centrifugal force. Since the rotating shaft is installed in the rectangular through groove, the rotating shaft drives the crushing roller to rotate in the opposite counterclockwise direction. The crushing roller produces a squeezing and crushing effect, thereby breaking up the blocky sediment material. The operation is convenient and effective.

[0013] 3. A filter screen is installed at the discharge port, and a scraper is provided on the side wall of the scraper plate. The lower surface of the scraper plate abuts against the upper surface of the filter screen. The cross-sectional shape of the scraper plate is a right trapezoid with the sharp end pointing upward. The scraper plate rotates with the scraper plate and is perpendicular to the scraper plate, so as to better scrape the upper surface of the filter screen plate and avoid the filter screen plate from being blocked, thus affecting the normal discharge of the discharge port.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0024] Example 1:

[0025] A lubricating oil additive anti-sedimentation mixing tank includes a tank body 1. A main infusion pipe 2 is connected to one side of the tank body 1, and several branch infusion pipes 3 are connected to the main infusion pipe 2. A discharge port 4 is provided at the lower end of the tank body 1, and a support leg 5 is welded to the lower end of the tank body 1. A stirring assembly 6 is installed inside the tank body 1, and an anti-sedimentation assembly 7 is installed at the lower end of the stirring assembly 6. The anti-sedimentation assembly 7 includes a synchronous shaft 71, connecting plates 72 are provided on both sides of the synchronous shaft 71, and a scraper 73 is provided at the lower end of the connecting plates 72. The outer side wall of the scraper 73 is attached to the inner side wall of the tank body 1, and the scraper 73 has a rectangular through groove 74. Several rotating shafts 75 are rotatably connected inside the tank 74. Crushing rollers 76 are fixedly sleeved on the rotating shafts 75. By setting the stirring component 6, the lubricating oil and additives can be fully contacted and mixed more evenly. This can also accelerate the mixing efficiency of the lubricating oil and additives and improve product quality. By setting the anti-sedimentation component 7, the sedimentation of some additives can be avoided due to long-term and frequent use or storage of the mixing tank. The blocky sediment raw materials on the inner wall and bottom of the tank 1 can be scraped off in time to ensure that the additive raw materials will not clump together and accumulate at the bottom of the mixing tank. This ensures normal material discharge from the outlet 4 and improves work efficiency.

[0026] When using the anti-sedimentation component 7, the synchronous shaft 71 rotates synchronously with the stirring component 6. The synchronous shaft 71 drives the connecting plate 72 and the scraper 73 to rotate synchronously. When the scraper 73 rotates clockwise to scrape off the blocky sediment material on the inner wall and bottom of the tank 1, the blocky sediment material is flipped upward and collided with the crushing roller 76 under the action of centrifugal force. Since the rotating shaft 75 is installed in the rectangular through groove 74, the rotating shaft 75 drives the crushing roller 76 to rotate in the opposite counterclockwise direction. The crushing roller 76 produces a squeezing and crushing effect, thereby breaking up the blocky sediment material. The operation is convenient and effective.

[0027] In this embodiment, the stirring assembly 6 includes a drive motor 61 installed on the upper end of the tank 1. The output end of the drive motor 61 passes through the tank 1 and is connected to a stirring shaft 62. Stirring rods 63 are provided on both sides of the stirring shaft 62. The stirring shaft 62 and the stirring rods 63 work together to make the lubricating oil and additives fully contact each other, mix more evenly, and accelerate the mixing efficiency of the lubricating oil and additives, thereby improving product quality.

[0028] In this embodiment, several strip baffles 8 are vertically welded to the inner wall of the tank 1. During the stirring and mixing process, the strip baffles 8 can further agitate the mixture of lubricating oil and additives, allowing them to come into full contact, resulting in more uniform mixing and higher efficiency.

[0029] In this embodiment, a filter screen plate 9 is installed at the discharge port 4, and a scraper plate 10 is provided on the side wall of the scraper plate 73. The lower surface of the scraper plate 10 abuts against the upper surface of the filter screen plate 9. The cross-sectional shape of the scraper plate 10 is a right trapezoid with the sharp end pointing upward. The scraper plate 10 rotates with the scraper plate 73 and is perpendicular to the scraper plate 73, so as to better scrape the upper surface of the filter screen plate 9 and avoid the filter screen plate 9 from being blocked, thereby affecting the normal discharge of the discharge port 4.

[0030] The working principle of this utility model is as follows: This lubricating oil additive anti-sedimentation mixing tank delivers lubricating oil to the tank body 1 through the main infusion pipe 2, and simultaneously delivers various additives that improve the performance of the lubricating oil to the tank body 1 through the branch infusion pipe 3. The stirring shaft 62 of the stirring assembly 6, in conjunction with the stirring rod 63, ensures full contact between the lubricating oil and the additives, resulting in a more uniform mixture and accelerating the mixing efficiency of the lubricating oil additives, thus improving product quality. The anti-sedimentation assembly 7 prevents sedimentation of some additives due to long-term frequent use or storage of the mixing tank. Specifically, when using the anti-sedimentation assembly 7, the synchronous shaft 71 rotates synchronously with the stirring assembly 6, and the synchronous shaft 71 carries... The moving connecting plate 72 and the scraper plate 73 rotate synchronously. When the scraper plate 73 rotates clockwise to scrape off the blocky sediment material on the inner wall and bottom of the tank 1, the blocky sediment material is driven to flip upward and collide with the crushing roller 76 under the action of centrifugal force. Since the rotating shaft 75 is installed in the rectangular through groove 74, the rotating shaft 75 drives the crushing roller 76 to rotate in the opposite counterclockwise direction. The crushing roller 76 produces a squeezing and crushing effect, thereby breaking up the blocky sediment material and scraping off the blocky sediment material on the inner wall and bottom of the tank 1 in time. This ensures that the additive raw materials will not clump together and accumulate at the bottom of the mixing tank, ensuring normal material discharge from the outlet 4 and improving work efficiency.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
