Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil mixing equipment, and in particular to a dynamic mixing and stirring device for multi-component lubricating oil. Background Technology

[0002] As a critical consumable in industrial and transportation sectors, the performance of lubricating oil is highly dependent on the homogeneity of its components. Modern lubricating oils are typically formulated with multiple base oils and more than ten functional additives, while some specialty lubricating oils also require the addition of novel functional materials such as nano-ceramic particles and graphene.

[0003] However, in existing technologies, traditional mixing devices mostly use fixed blade combinations, which have poor adaptability to materials with different viscosities. For mixing high-viscosity base oil and low-viscosity additives, the fixed-angle propulsion blades are difficult to generate sufficient axial flow, resulting in the deposition of heavy components at the bottom of the tank. On the other hand, the turbine blades have a fixed shearing zone, which has limited ability to break up difficult-to-disperse materials such as nanoparticles and polymers, and is prone to local agglomeration. A single fixed structure has poor mixing effect on different components. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing technologies, such as poor adaptability to materials of different viscosities, difficulty in generating sufficient axial flow with fixed-angle propeller blades when mixing high-viscosity base oils and low-viscosity additives, leading to the deposition of heavy components at the bottom of the tank; and the fixed shearing zone of turbine blades, which has limited ability to break up difficult-to-disperse materials such as nanoparticles and polymers, easily forming local agglomeration, and poor mixing effect of single fixed structures for different components. Therefore, a multi-component lubricating oil dynamic mixing and stirring device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-component lubricating oil dynamic mixing and stirring device, comprising a mixing tank, a tank cover mounted on the top surface of the mixing tank, a geared motor mounted on the top surface of the tank cover, a hydraulic cylinder mounted on one side of the geared motor, the hydraulic cylinder mounted on the top surface of the tank cover, a drive shaft mounted inside the mixing tank, the top end of the drive shaft being connected to the output shaft end of the geared motor, and a dynamic blade mechanism mounted on the outer wall of the drive shaft, the dynamic blade mechanism comprising a fixed base, deflecting blades, a control rod, a pressure plate, a sleeve, a lifting base, and a traction mechanism. The rod and bearing are fixedly sleeved on the outer wall of the drive shaft. There are two deflecting blades, which are rotatably connected to the outer walls of the fixed base on both sides. One end of the control rod is fixedly connected to the rotating shaft of the deflecting blade, and the other end of the control rod is movably connected to the bottom end of the traction rod. The top end of the traction rod is movably connected to the outer wall of the lifting seat. The lifting seat is movably connected to the outer wall of the drive shaft. The sleeve is fixedly connected to the top surface of the lifting seat and is sleeved on the outside of the drive shaft. The bearing is installed between the pressure plate and the sleeve. The bottom end of the telescopic rod of the hydraulic cylinder is fixedly connected to one end of the pressure plate.

[0006] Preferably, a dispersing disc is fixedly connected to the bottom end of the drive shaft, and an agitator is provided above the dispersing disc, with the agitator fixedly sleeved on the outer wall of the drive shaft.

[0007] Preferably, a support base is installed at the center of the top surface of the can lid, and the geared motor is fixedly installed on the top surface of the support base.

[0008] Preferably, the drive shaft is rotatably connected to the inner wall of the support base.

[0009] Preferably, an oil drain pipe is fixedly connected to the center of the bottom surface of the mixing tank.

[0010] Preferably, an oil injection pipe is connected through the top surface of the tank lid, and multiple sets of oil injection pipes are provided.

[0011] Preferably, the inside of the oil injection pipe is connected to the inside of the mixing tank, and a connector is fixedly installed at the top of the oil injection pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the dynamic blade mechanism is controlled by starting the geared motor to drive the transmission shaft to rotate and stir and mix the multi-component lubricating oil in the mixing tank. During the stirring process, the pressure plate is controlled to move up and down by the hydraulic cylinder. With the transmission control of the control rod and the traction rod, the deflection blade is deflected at an adjustable angle. Thus, the blade tilt angle is adjusted in real time according to the viscosity of the lubricating oil. The propulsion angle is increased when the viscosity is high and the shearing is enhanced when the viscosity is low. This avoids the limitation of the single fixed structure on the mixing effect of different components and improves the mixing effect of lubricating oil and processing efficiency.

[0014] 2. In this utility model, the lubricating oil is stirred and mixed by the synchronous rotation of the stirring paddle and the dispersing disc along with the drive shaft, realizing multiple compound stirring. The dispersing disc is used to strengthen the high shear zone, break up large particles of additives or emulsion droplets, and improve the micro-mixing precision. Through the combination of multiple blades and different stirring methods, the multi-component lubricating oil can be fully mixed at the macro and micro levels, ensuring that the various performance indicators of the mixed lubricating oil are stable and uniform.

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.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a multi-component lubricating oil dynamic mixing and stirring device, including a mixing tank 1, a tank cover 2 installed on the top surface of the mixing tank 1, a geared motor 4 installed on the top surface of the tank cover 2, a hydraulic cylinder 5 installed on one side of the geared motor 4, the hydraulic cylinder 5 installed on the top surface of the tank cover 2, a drive shaft 6 installed inside the mixing tank 1, the top end of the drive shaft 6 being connected to the output shaft end of the geared motor 4, a dynamic blade mechanism 7 installed on the outer wall of the drive shaft 6, the dynamic blade mechanism 7 including a fixed base 71, a deflecting blade 72, a control rod 73, a pressure plate 74, a sleeve 75, a lifting base 76, a traction rod 77, and a bearing 78, the fixed base 71... Two deflecting blades 72 are fixedly sleeved on the outer wall of the drive shaft 6. The two deflecting blades 72 are rotatably connected to the outer walls of the fixed seat 71 on both sides. One end of the control rod 73 is fixedly connected to the rotating shaft of the deflecting blade 72, and the other end of the control rod 73 is movably connected to the bottom end of the traction rod 77. The top end of the traction rod 77 is movably connected to the outer wall of the lifting seat 76. The lifting seat 76 is movably connected to the outer wall of the drive shaft 6. The sleeve 75 is fixedly connected to the top surface of the lifting seat 76 and is sleeved on the outside of the drive shaft 6. The bearing 78 is installed between the pressure plate 74 and the sleeve 75. The bottom end of the telescopic rod of the hydraulic cylinder 5 is fixedly connected to one end of the pressure plate 74.

[0023] The specific settings and functions of this embodiment are described below. By starting the reduction motor 4 to drive the transmission shaft 6 to rotate, the dynamic blade mechanism 7 is controlled to stir and mix the multi-component lubricating oil in the mixing tank 1. During the stirring process, the hydraulic cylinder 5 controls the pressure plate 74 to move up and down. With the transmission control of the control rod 73 and the traction rod 77, the deflection blade 72 is deflected at an adjustable angle. This allows the blade tilt angle to be adjusted in real time according to the viscosity of the lubricating oil. When the viscosity is high, the propulsion angle is increased, and when the viscosity is low, the shearing is enhanced. This avoids the limitation of a single fixed structure on the mixing effect of different components, and improves the mixing effect of the lubricating oil and the processing efficiency.

[0024] Example 2: Figure 1 - Figure 4 As shown, a dispersing disc 9 is fixedly connected to the bottom end of the drive shaft 6, and an agitator 8 is provided above the dispersing disc 9. The agitator 8 is fixedly sleeved on the outer wall of the drive shaft 6. A support base 41 is installed at the center of the top surface of the tank cover 2.

An oil injection pipe 3 is connected through the top surface of the tank cover 2. Multiple sets of oil injection pipes 3 are provided. The interior of the oil injection pipe 3 is connected to the interior of the mixing tank 1. A connector 31 is fixedly installed at the top end of the oil injection pipe 3.

[0025] The overall effect of this embodiment is that the lubricating oil is stirred and mixed by the synchronous rotation of the stirring paddle 8 and the dispersing disc 9 along with the drive shaft 6, achieving multiple compound stirring. The dispersing disc 9 is used to strengthen the high shear zone, break up large particles of additives or emulsion droplets, and improve the micro-mixing precision. Through the combination of various blades and different stirring methods, the multi-component lubricating oil can be fully mixed at both the macro and micro levels, ensuring that the various performance indicators of the mixed lubricating oil are stable and uniform. The oil injection pipe 3 and the connector 31 make it convenient for users to inject different components of lubricating oil fillers into the mixing tank 1 through the oil injection pipe 3.

[0026] The usage and working principle of this device are as follows: During use, the user injects lubricating oil fillers of different components into the mixing tank 1 through the oil injection pipe 3. The user starts the reduction motor 4 to drive the transmission shaft 6 to rotate, controlling the dynamic blade mechanism 7, the stirring blade 8 and the dispersing disc 9 to stir and mix in the mixing tank 1, achieving multiple compound stirring. The dispersing disc 9 is used to strengthen the high shear area and break up large particles of additives or emulsion droplets. At the same time, during the stirring process, the pressure plate 74 is controlled to move up and down by the hydraulic cylinder 5. With the transmission control of the control rod 73 and the traction rod 77, the deflection blade 72 deflects at an adjustable angle, thereby adjusting the blade tilt angle in real time according to the viscosity of the lubricating oil. The propulsion angle is increased when the viscosity is high and the shear is enhanced when the viscosity is low.
