Description

Technical Field

[0001] This utility model mainly relates to the technical field of lubricating oil raw material mixing, specifically a lubricating oil base oil and additive mixing device. Background Technology

[0002] Lubricating oil is a type of functional fluid used to reduce mechanical friction, lower equipment wear, and also has functions such as cooling, cleaning, rust prevention, and sealing. It is widely used in various mechanical systems such as engines, gearboxes, machine tools, and industrial equipment. It is a key auxiliary material to ensure the long-term stable operation of machinery. Its core components include two parts: base oil and additives. Base oil is the main component of lubricating oil and mainly determines its basic physicochemical properties. Additives are small amounts of functional chemical substances added to compensate for the shortcomings of base oil and to give lubricating oil new functions. Through the scientific blending of base oil and additives, lubricating oil can meet the specific usage requirements under different working conditions.

[0003] The lubricating oil base oil and additive mixing device is a special equipment used to efficiently blend the lubricating oil base oil and additives in a specific ratio. Its core function is to ensure that the two are evenly dispersed through precise temperature control, stirring and mixing process to form a lubricating oil semi-finished product or finished product with stable performance. It mainly includes a tank, stirring motor, stirring paddle, cover plate, coil, pipeline and control part.

[0004] Currently, existing mixing devices mainly use a stirring motor to drive a stirring paddle to mix raw materials, and a coil to control the temperature inside the tank. The movement of the stirring paddle is mostly unidirectional rotation. Unidirectional rotation can only form a single circulation inside the tank. The unidirectional shear force is weak and it is easy to create mixing dead zones. As a result, it is difficult for the base oil and additives to achieve microscopic uniform dispersion quickly. Therefore, it takes more than 40 minutes to complete the blending of 10 tons, which is inefficient and consumes a lot of energy. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a mixing device for lubricating oil base oil and additives, which solves the technical problem mentioned in the background that the stirring paddle in current mixing devices mostly rotates in one direction, has weak shear force, and requires a long time to mix the raw materials evenly, resulting in low efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A lubricating oil base oil and additive mixing device includes a tank and a cover located at the upper opening of the tank. The tank is provided with a temperature regulating coil, and a bidirectional stirring mechanism is provided at the central axis of the coil. The bidirectional stirring mechanism includes a first rotating shaft and a second rotating shaft, which are located on the same central axis, and the rotation direction of the second rotating shaft is opposite to that of the first rotating shaft. Multiple stirring blades are provided on both the first and second rotating shafts, and the stirring blades are distributed in an equidistant spiral.

[0008] Furthermore, a reversing component is provided at the lower end of the first rotating shaft. The reversing component includes a first gear, which is sleeved on the lower end of the first rotating shaft. The first gear is meshed with a second gear. A connecting shaft is provided on the second gear, and the lower end of the connecting shaft is connected to the bottom of the tank. The second gear is meshed with a toothed ring, and the toothed ring is located on the inner wall of the second rotating shaft.

[0009] Furthermore, multiple locking blocks are evenly spaced around the inner wall of the second rotating shaft, each locking block engaging with a locking groove, and the locking groove is located on the outer wall of the gear ring.

[0010] Furthermore, a bearing is provided at the connection point between the second rotating shaft and the first rotating shaft.

[0011] Furthermore, the cover includes a connecting plate and a rotating plate, which are hinged together. A motor is provided on the connecting plate, and the output end of the motor is connected to the upper interface of the first rotating shaft.

[0012] Furthermore, the coil has multiple clamps on its wall, which are connected to the inner wall of the tank by bolts.

[0013] Furthermore, a liquid outlet is provided at the bottom of the outer wall of the tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the arrangement of a first rotating shaft, a second rotating shaft, a stirring blade, a first gear, a second gear, a gear ring, a connecting shaft, and a bearing, achieves a material circulation field with vertical convection within the tank during the mixing of base oil and additives. This breaks the traditional single circulation mode of unidirectional rotation, effectively eliminating mixing dead zones. At the same time, the superimposed shear force generated by the reverse rotation can quickly disperse agglomerated particles in the base oil and additives, greatly shortening the mixing time, effectively improving the uniformity of additive dispersion in the base oil, avoiding fluctuations in the performance of the finished lubricating oil caused by uneven local concentration, and significantly improving mixing efficiency and product quality stability.

[0016] In addition, the reverse convection flow field can scour the tank wall and bottom, reduce material adhesion and sedimentation, reduce cleaning difficulty and frequency, reduce equipment maintenance costs and downtime for repairs, improve equipment operating economy, and has a stable structure and is easy to install, thus having certain practical value.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0027] Please refer to the appendix carefully. Figure 1-5 A mixing device for lubricating oil base oil and additives includes a tank 1 and a cover 2 located at the upper opening of the tank 1. A temperature regulating coil 4 is provided inside the tank 1. A bidirectional stirring mechanism 5 is provided at the central axis of the coil 4. The bidirectional stirring mechanism 5 includes a first rotating shaft 51 and a second rotating shaft 52. The second rotating shaft 52 is hollow inside and open at both the upper and lower ends. The lower end of the second rotating shaft 52 is connected to the bottom of the inner wall of the tank 1 through a shaft seal. The first rotating shaft 51 and the second rotating shaft 52 are on the same central axis, and the rotation direction of the second rotating shaft 52 is opposite to the rotation direction of the first rotating shaft 51. Multiple stirring blades 53 are provided on both the first rotating shaft 51 and the second rotating shaft 52, and the stirring blades 53 are distributed in an equidistant spiral.

[0028] The above structure enables the formation of an up-and-down convection material circulation field within tank 1 during the mixing of base oil and additives. This breaks the traditional single-circulation mode of unidirectional rotation, effectively eliminating mixing dead zones. At the same time, the superimposed shear force generated by the reverse rotation can quickly disperse agglomerated particles in the base oil and additives, greatly shortening the mixing time and effectively improving the dispersion uniformity of additives in the base oil. This avoids fluctuations in the performance of the finished lubricating oil caused by uneven local concentrations, significantly improving mixing efficiency and product quality stability. Furthermore, the structure is stable, easy to install, and has certain practical value.

[0029] The specific operation is as follows: First, the measured base oil is poured into tank 1. Then, motor 3 is turned on, which drives the first rotating shaft 51 to rotate clockwise. At the same time, the first rotating shaft 51 drives the first gear 541 to rotate synchronously. The first gear 541 meshes with the second gear 542, and the second gear 542 rotates counterclockwise. Subsequently, the second gear 542 drives the gear ring 543 to rotate counterclockwise, thereby causing the second rotating shaft 52 to rotate counterclockwise. The stirring blades 53 on the two rotating shafts rotate in opposite directions, forming a convection circulation. After the base oil circulation stabilizes, various additives are added in batches according to the proportion. The temperature inside tank 1 is controlled within a suitable range using coil 4 (which can be filled with steam, heat transfer oil, or other heat or cold media to control the material temperature). The superimposed shear force generated by bidirectional stirring promotes the dispersion of additives. Under the premise of ensuring the uniformity of mixing, the stirring time is greatly shortened. During this period, samples can be taken to test and confirm the uniformity of mixing. After the standard is met, stirring is stopped, and then the mixture is discharged through outlet 11.

[0030] Please refer to the appendix carefully. Figure 1 and attached Figure 2 The cover 2 includes a connecting plate 21 and a rotating plate 22, which are hinged together. A motor 3 is installed on the connecting plate 21, and the output end of the motor 3 is connected to the upper interface of the first rotating shaft 51. The motor 3 provides driving force for the rotation of the rotating shaft. Multiple clips 6 are installed on the wall of the coil 4. The clips 6 are connected to the inner wall of the tank 1 by bolts. The clips 6 enable the coil 4 to be stably installed on the inner wall of the tank 1. A liquid outlet 11 is provided at the bottom of the outer wall of the tank 1. The mixed lubricant is discharged from the tank 1 through the liquid outlet 11.

[0031] Please refer to the appendix carefully. Figure 3 , Figure 4 and attached Figure 5 A reversing assembly 54 is provided at the lower end of the first rotating shaft 51. The reversing assembly 54 includes a first gear 541, which is sleeved on the lower end of the first rotating shaft 51. The first gear 541 is meshed with a second gear 542. A connecting shaft 544 is provided on the second gear 542, and the lower end of the connecting shaft 544 is connected to the bottom of the tank body 1. The second gear 542 is meshed with a gear ring 543, and the gear ring 543 is located on the inner wall of the second rotating shaft 52. Through the reversing assembly 54, the rotation of the first rotating shaft 51 can be reversed. Simultaneously, the second rotating shaft 52 is driven to rotate in the opposite direction. Multiple locking blocks 521 are evenly spaced around the inner wall of the second rotating shaft 52. Each locking block 521 is engaged with a locking groove 545, which is located on the outer wall of the toothed ring 543. Through the mutual cooperation between the locking blocks 521 and the locking grooves 545, the toothed ring 543 is stably installed on the inner wall of the second rotating shaft 52. A bearing 55 is provided at the connection position between the second rotating shaft 52 and the first rotating shaft 51. Through the bearing 55, the second rotating shaft 52 is stably rotated on the first rotating shaft 51.
