Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a lubricating oil additive mixing device. Background Technology

[0002] Lubricating oil additives are one or more compounds added to lubricating oil to give it new properties or improve some of its existing properties. Additives are mainly classified by function into antioxidants, anti-wear agents, friction modifiers, extreme pressure additives, detergents, dispersants, foam inhibitors, corrosion and rust inhibitors, pour point improvers, and viscosity index enhancers.

[0003] Among existing lubricating oil additive mixing devices, such as the one disclosed in document CN213314525U, a lubricating oil additive mixing device is designed with a cleaning rod and a cleaning scraper. These components prevent lubricating oil additive residue from remaining on the inner wall of the mixing tank, facilitating cleaning during use and indirectly improving the mixing effect of the additive. Furthermore, the combination of a second mixing motor and a first mixing motor, where the second mixing motor works in conjunction with the first mixing motor, further enhances the mixing effect of the lubricating oil additive, increasing mixing efficiency and shortening processing time. The overall effect is better than traditional methods.

[0004] In the aforementioned prior art, two motors are used to mix the lubricating oil additive. The dual-motor system requires more materials and components. The simultaneous operation of the two motors places higher demands on the voltage and stability of the power grid, and the maintenance difficulty and complexity are also higher, which increases the overall manufacturing and maintenance costs. Furthermore, when removing the lubricating oil, there is a lack of certain filtering components, and impurities are easily mixed into the lubricating oil during the addition and mixing process, which affects the quality of the lubricating oil. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a lubricating oil additive mixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lubricating oil additive mixing device includes a mixing tank. An injection pipe and a discharge pipe are respectively provided at the top and bottom of the mixing tank. A shaft tube is rotatably provided at the top of the mixing tank, and the bottom end of the shaft tube extends into the mixing tank and is fitted with a mixing component I. A rotating shaft is provided inside the shaft tube, and the rotating shaft and shaft tube are rotatable. The bottom end of the rotating shaft extends into the mixing tube and is fitted with a mixing component II. A driving mechanism is installed at the top of the mixing tank, and the driving mechanism synchronously drives the shaft tube and rotating shaft to rotate in opposite directions. A filter assembly is provided at the bottom of the mixing tank and is connected to the discharge pipe.

[0008] Preferably, the drive mechanism includes a support plate fixedly installed on the top of the mixing tank. Two spaced brackets are fixedly connected from top to bottom on the inner side of the support plate. The top end of the shaft tube passes through the lower bracket and is rotatably connected to it.

[0009] Preferably, a motor is fixedly installed on the back of the support plate, the output shaft of the motor passes through the support plate and is fixedly connected to a worm gear, and a worm wheel matching the worm gear is fixedly sleeved on the outer wall of the support rod.

[0010] Preferably, the two bevel gears II and III are arranged opposite to each other, and the reduction ratio of the worm and worm wheel is 10.

[0011] Preferably, the mixing component I includes two spaced-apart circular plates, with the top circular plate fixedly sleeved on the bottom end of the shaft tube, and a plurality of circumferentially arrayed blades fixedly connected between the outer rings of the two circular plates.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, efficient mixing of lubricating oil and additives can be achieved through mixing component I and mixing component II. The blades and scrapers of mixing component I can effectively stir the lubricating oil, prevent additives from remaining on the inner wall of the mixing tank, and ensure that the additives are fully integrated into the lubricating oil.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-5 As shown, this utility model provides a lubricating oil additive mixing device, including a mixing tank 100. The top and bottom of the mixing tank 100 are respectively provided with an injection pipe 101 and a discharge pipe 102. The top of the mixing tank 100 is rotatably provided with a shaft tube 200. The bottom end of the shaft tube 200 extends into the mixing tank 100 and is equipped with a mixing component I 300. The inner side of the shaft tube 200 is provided with a rotating shaft 400, which is rotatable with the shaft tube 200. The bottom end of the rotating shaft 400 extends into the mixing tube and is equipped with a mixing component II 500. The top of the mixing tank 100 is equipped with a driving mechanism 600, which synchronously drives the shaft tube 200 and the rotating shaft 400 to rotate in opposite directions. The bottom of the mixing tank 100 is provided with a filter component 700 that is connected to the discharge pipe 102.

[0028] In this embodiment, the drive mechanism 600 includes a support plate 601 fixedly installed on the top of the mixing tank 100. Two spaced brackets 602 are fixedly connected from top to bottom on the inner side of the support plate 601. The top end of the shaft tube 200 passes through the lower bracket 602 and is rotatably connected to it. The top end of the rotating shaft 400 is rotatably connected to the upper bracket 602. A support rod 603 is rotatably connected to the inner side of the support plate 601. A bevel gear I 604 is fixedly sleeved on the outer side of the support rod 603. A bevel gear II 605 that meshes with the bevel gear I 604 is fixedly sleeved on the outer wall of the shaft tube 200. A bevel gear III 606 that meshes with the bevel gear II 605 is fixedly sleeved on the outer wall of the rotating shaft 400.

[0029] In this embodiment, a motor 607 is fixedly installed on the back of the support plate 601. The output shaft of the motor 607 passes through the support plate 601 and is fixedly connected to a worm gear 608. A worm wheel 609 matching the worm gear 608 is fixedly sleeved on the outer wall of the support rod 603. Two bevel gears II 605 and bevel gear III 606 are arranged opposite to each other. The reduction ratio of the worm gear 608 and the worm wheel 609 is 10. Since the bevel gears II 605 and III 606 are arranged opposite to each other, when the bevel gears II 605 and III 606 are driven by the bevel gear I 604, they rotate in opposite directions. And since the reduction ratio of the worm gear 608 and the worm wheel 609 is 10, it can reduce speed by a large proportion, increase torque, make the transmission smoother and more stable, and improve the user experience.

[0030] In this embodiment, the mixing component I 300 includes two spaced-apart circular plates 301. The top circular plate 301 is fixedly sleeved on the bottom end of the shaft tube 200. A plurality of circumferentially arrayed blades 302 are fixedly connected between the outer rings of the two circular plates 301. The blades 302 are bent. The edges of the blades 302 are fixedly connected to scrapers 303 that contact the inner wall of the mixing tank 100. The rotation of the shaft tube 200 drives the circular plates 301 to rotate the blades 302, thereby mixing and stirring the lubricating oil in the mixing tank 100. The scrapers 303 contact the inner wall of the mixing tank 100, which can prevent lubricating oil additives from remaining on the inner wall of the mixing tank 100.

[0031] In this embodiment, the mixing component II 500 includes a plurality of mixing blades 501 fixedly connected to the outer wall of the rotating shaft 400. The plurality of mixing blades 501 are spirally arranged and inclined along the rotating shaft 400. The surface of the mixing blades 501 is provided with a plurality of diversion holes 502. The plurality of spirally arranged and inclined mixing blades 501 generate shear force on the lubricating oil, and the diversion holes 502 allow the lubricating oil to pass through and achieve diversion.

[0032] In this embodiment, the filter assembly 700 includes a forked rod 701 fixedly connected to the bottom of the mixing tank 100. Multiple ends of the forked rod 701 are fixedly connected to connecting pipes 702 that can dock with the discharge pipe 102. A filter screen 703 is fixedly connected inside the connecting pipe 702. A threaded pipe 704 is threadedly connected to the outer wall of the connecting pipe 702. The outer wall of the discharge pipe 102 is provided with external threads. The threaded pipe 704 is threadedly engaged with the discharge pipe 102 through the external threads. The connection between the discharge pipe 102 and the connecting pipe 702 is realized through the threaded pipe 704. The lubricating oil discharged from the discharge pipe 102 will be filtered by the filter screen 703 to improve the quality of the lubricating oil. The filter screen 703 can be replaced after long-term use.

[0033] In this embodiment, a limiting ring 103 is fixedly sleeved on the outer wall of the discharge pipe 102, and a handle 705 is fixedly connected to the outer wall of the threaded pipe 704. The limiting plate limits the threaded pipe 704 to prevent the threaded pipe 704 from separating from the connecting pipe 702, ensuring that the threaded pipe 704 connects the discharge pipe 102 and the connecting pipe 702 together. The handle 705 facilitates the rotation of the threaded pipe 704.

[0034] How to use and how to work this device:

[0035] In operation, the device first adds lubricating oil and various additives through the injection pipe 101. At this time, the discharge pipe 102 is closed. The motor 607 is started, causing the worm gear 608 to rotate, which in turn drives the worm wheel 609 to rotate. The worm wheel 609 drives the support rod 603, causing the bevel gear I 604 to rotate. The bevel gear I 604 synchronously drives the bevel gears II 605 and III 606 to rotate. Since the bevel gears II 605 and III 606 are arranged opposite to each other, they rotate in opposite directions. The bevel gear II 605 can drive the shaft tube 200 to rotate. The circular plate 301 drives the blade 302 to rotate, mixing and stirring the lubricating oil in the mixing tank 100. The scraper 303 contacts the inner wall of the mixing tank 100, which can prevent the lubricating oil additive from remaining on the inner wall of the mixing tank 100. The bevel gear III 606 can drive the rotating shaft 400 to rotate, and the rotating shaft 400 drives the mixing blade 501 to rotate, generating a shearing force on the lubricating oil. The blade 302 and the mixing blade 501 exert opposite forces on the lubricating oil, which can accelerate the mixing efficiency and mixing effect of the lubricating oil additive. Compared with the existing technology, the overall manufacturing cost and maintenance cost are effectively reduced.

[0036] After mixing is complete, the drain pipe 102 can be opened for discharge. During discharge, the lubricating oil will be filtered through the filter screen 703 to remove impurities and improve the quality of the lubricating oil. The filter screen 703 can be replaced after long-term use, making it more convenient to use.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
