Description

Technical Field

[0001] This utility model relates to the field of lubricating oil processing technology, specifically to a lubricating oil mixing tank with a cooling structure. Background Technology

[0002] In the process of rapid development of modern industry, various types of machinery and equipment are widely used in various fields, from large-scale industrial production equipment to precision instruments. The normal operation of machinery is crucial to ensuring production efficiency and product quality. As a key liquid lubricant that ensures the stable operation of machinery, lubricating oil plays an irreplaceable role. It can not only reduce friction between mechanical parts and reduce wear, but also play multiple roles such as cooling, rust prevention, cleaning, sealing and buffering, effectively extending the service life of machinery and improving its operating efficiency.

[0003] Currently, although some technical solutions have been developed to address the cooling problem during the lubricating oil mixing process, such as the low-temperature reaction vessel for lubricating oil disclosed in publication number "CN222034730U," which incorporates cooling components around the reactor body to cool the mixture via distribution pipes, this cooling method has significant limitations. Its cooling is primarily concentrated on the exterior of the reactor body, offering limited effectiveness for cooling the interior of the lubricating oil. It is difficult to quickly and effectively reduce the internal heat generated by stirring, thus failing to meet the demands of production scenarios requiring high lubricating oil quality. Therefore, we propose a lubricating oil mixing tank with a cooling structure. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a lubricating oil mixing tank with a cooling structure. The technical solution adopted is as follows: it includes a mixing tank, and an inner tank is provided inside the mixing tank.

A first electric valve is provided on the discharge pipe and the feed pipe respectively. A drain pipe is provided at the bottom center of the mixing tank, and a second electric valve is provided in the middle of the drain pipe. A stirring unit is provided in the middle of the inner tank, and the stirring unit is connected to a second injection pipe provided above the mixing tank.

[0005] As a preferred technical solution of this utility model, it also includes a spiral guide plate, which is disposed in the middle between the inner tank and the mixing tank, and the spiral guide plate is fixedly connected to the outer side of the inner tank and the inner side of the mixing tank.

[0006] As a preferred embodiment of this utility model, the stirring unit includes a drive motor, a top shaft tube, a drive gear, a driven gear, a stirring tube, and a bottom shaft tube. The top shaft tube is rotatably installed at the top center of the mixing tank and the inner tank, and a rotary sealing pipe joint at the top of the top shaft tube is rotatably connected to the bottom of the second injection pipe. A bottom shaft tube is located directly below the top shaft tube and is rotatably installed at the bottom center of the inner tank. The bottom of the bottom shaft tube is connected to the interior of the mixing tank. Four stirring tubes are arranged in a circumferential array at equal intervals on the top of the bottom shaft tube. The stirring tubes are C-shaped. The bottom of each stirring tube is connected to the top of the bottom shaft tube, and the top of each stirring tube is connected to the bottom of the top shaft tube. A driven gear is located in the middle of the outer side of the top shaft tube. A drive motor is located above and behind the driven gear and is fixedly installed on the top of the mixing tank. The output shaft of the drive motor passes through a through hole at the top of the mixing tank and is fixedly connected to the drive gear inside the mixing tank. The teeth on the drive gear and the driven gear mesh.

[0010] The beneficial effects of this utility model are as follows: This utility model drives the top shaft tube, bottom shaft tube, and stirring tube to rotate via a drive motor. During the rotation of the stirring tube, the lubricating oil raw material in the inner tank is fully stirred, so that various components can be evenly dispersed, effectively improving the mixing quality of the lubricating oil. In addition, a cooling method combining internal and external cooling is adopted. Coolant is injected into the stirring unit through the second injection pipe, and heat exchange occurs with the lubricating oil raw material during the stirring process, directly reducing the temperature of the lubricating oil. Coolant is injected into the interlayer between the mixing tank and the inner tank through the first injection pipe, which cools the inner tank. This dual cooling mechanism effectively prevents the lubricating oil from being affected by excessively high temperature during the stirring process, thus ensuring the quality stability of the lubricating oil.

[0016] Example 1

[0017] like Figures 1 to 4As shown, this utility model discloses a lubricating oil mixing tank with a cooling structure. The technical solution includes a mixing tank 1, with an inner tank 2 inside. The top left end of the inner tank 2 is connected to a feed pipe 6 located at the top of the mixing tank 1, and the bottom right end of the inner tank 2 is connected to a discharge pipe 8 located at the bottom of the mixing tank 1. First electric valves 7 are respectively installed on the discharge pipe 8 and the feed pipe 6. A drain pipe 9 is located at the center of the bottom of the mixing tank 1, and a second electric valve 10 is located in the middle of the drain pipe 9. The system also includes a first injection pipe 11, located at the top right end of the mixing tank 1 and connected to the interior of the mixing tank 1. Through the first injection pipe 11, fluid is injected into the mixing tank 1 and the inner tank. Coolant is injected into the interlayer between the inner tank 2 and the mixing tank 1. The coolant in the interlayer can cool the inner tank 2 and prevent the lubricating oil from being affected by excessive temperature during the mixing process. A spiral guide plate 4 is also included. The spiral guide plate 4 is located in the middle between the inner tank 2 and the mixing tank 1, and is fixedly connected to the outer side of the inner tank 2 and the inner side of the mixing tank 1. The spiral guide plate 4 allows the coolant to flow along a spiral path, increasing the contact time and area between the coolant and the inner tank 2, thus improving the cooling effect. A stirring unit 5 is located in the middle of the inner tank 2. The stirring unit 5 is connected to the second injection pipe 12 located above the mixing tank 1. The stirring unit 5 includes a drive motor 51, a top shaft tube 52, a drive gear 53, and a driven gear. 54. A stirring tube 55 and a bottom shaft tube 56 are attached. A top shaft tube 52 is rotatably installed at the top center of the mixing tank 1 and the inner tank 2. A rotary sealing pipe joint at the top of the top shaft tube 52 is rotatably connected to the bottom of the second injection pipe 12. A bottom shaft tube 56 is located directly below the top shaft tube 52 and is rotatably installed at the bottom center of the inner tank 2. The bottom of the bottom shaft tube 56 is connected to the interior of the mixing tank 1. Four stirring tubes 55 are arranged in a C-shape at equal intervals on the top of the bottom shaft tube 56. The bottoms of the stirring tubes 55 are connected to the tops of the bottom shaft tube 56, and the tops of the stirring tubes 55 are connected to the bottoms of the top shaft tube 52. A driven gear 54 is located on the outer center of the top shaft tube 52. A drive motor 51 is provided above and behind the driven gear 54, and the drive motor 51 is fixedly installed on the top of the mixing tank 1. The output shaft of the drive motor 51 passes through the through hole provided on the top of the mixing tank 1 and is fixedly connected to the drive gear 53 provided inside the mixing tank 1. The drive gear 53 meshes with the teeth on the driven gear 54. The drive motor 51 is started by the controller 3. The output shaft of the drive motor 51 drives the driven gear 54 to rotate through the drive gear 53, which in turn drives the top shaft tube 52 to rotate. When the top shaft tube 52 rotates, it will drive the bottom shaft tube 56 and the stirring tube 55 to rotate together. During the rotation, the stirring tube 55 not only fully stirs and mixes the lubricating oil raw materials in the inner tank 2, but also makes the various components evenly dispersed.The top shaft tube 52 is rotatably installed at the top center of the mixing tank 1 and the inner tank 2, and its top rotating sealing pipe joint is rotatably connected to the bottom of the second injection pipe 12, ensuring that the second injection pipe 12 can normally inject coolant into the stirring unit 5 during rotation. The coolant injected by the second injection pipe 12 enters the stirring pipe 55 through the top shaft tube 52, then flows from the stirring pipe 55 into the bottom shaft tube 56, and finally enters the interior of the mixing tank 1, where it exchanges heat with the lubricating oil raw material during stirring. It also includes support legs 13, of which three are arranged in a circumferential array at equal intervals at the bottom of the mixing tank 1, providing stable support for the mixing tank 1. Furthermore, it includes a controller 3, located at the front bottom of the mixing tank 1. The output of the controller 3 is electrically connected to the input of the drive motor 51, the first electric valve 7, and the second electric valve 10. The input of the controller 3 is electrically connected to the output of an external power supply, allowing operators to easily control the drive motor 51, the first electric valve 7, and the second electric valve 10.

[0018] The working principle of this utility model is as follows: During use, the controller 3 opens the first electric valve 7 on the feed pipe 6, allowing the lubricating oil raw materials and additives to be mixed to be injected into the inner tank 2 through the feed pipe 6. The inner tank 2 provides a relatively independent space for lubricating oil mixing, and the interlayer between the inner tank 2 and the mixing tank 1 provides good temperature insulation. During the mixing process, the controller 3 starts the drive motor 51, and the output shaft of the drive motor 51 drives the driven gear 54 to rotate through the drive gear 53, thereby driving the top shaft tube 52 to rotate. The top shaft tube 52 is rotatably mounted between the mixing tank 1 and the inner tank. The top center of the 2nd injection pipe has a rotating sealing pipe joint that is rotatably connected to the bottom of the second injection pipe 12, ensuring that the second injection pipe 12 can normally inject coolant into the stirring unit 5 during rotation, achieving internal cooling. When the top shaft pipe 52 rotates, it will drive the bottom shaft pipe 56 and the stirring pipe 55 to rotate together. During the rotation of the stirring pipe 55, it not only fully stirs and mixes the lubricating oil raw materials in the inner tank 2, making the various components evenly dispersed, but also the coolant injected from the second injection pipe 12 enters the stirring pipe 55 through the top shaft pipe 52, and then flows from the stirring pipe 55 into the bottom shaft pipe 56. Finally, the lubricating oil enters the mixing tank 1 and exchanges heat with the lubricating oil raw materials during the stirring process, further reducing the temperature of the lubricating oil and achieving a synergistic effect of internal cooling and stirring. During the stirring process, coolant can be injected into the interlayer between the mixing tank 1 and the inner tank 2 through the first injection pipe 11 located at the top right end of the mixing tank 1 and connected to the inside of the mixing tank 1, as needed. The coolant in the interlayer can cool the inner tank 2, preventing the lubricating oil from affecting its performance due to excessive temperature during the mixing process. At the same time, the spiral guide plate 4 located in the middle between the inner tank 2 and the mixing tank 1 plays a role in cooling the inner tank 2. The fixed connection between the outer side of the inner tank 2 and the inner side of the mixing tank 1 allows the coolant to flow along a spiral path, increasing the contact time and area between the coolant and the inner tank 2, thus improving the cooling effect. Finally, after the lubricating oil is mixed, the first electric valve 7 on the discharge pipe 8 is opened, and the mixed lubricating oil is discharged from the inner tank 2 through the discharge pipe 8 for subsequent storage or use. At this time, the coolant in the interlayer between the mixing tank 1 and the inner tank 2, as well as the coolant used for internal cooling in the stirring unit 5, can be discharged from the equipment through the second electric valve 10 in the middle of the discharge pipe 9 by the controller 3.
