Description

Technical Field

[0001] This utility model relates to the field of lubricating oil additive processing technology, specifically a nanoscale dispersion and homogenization device for lubricating oil molybdenum-bismuth additives. Background Technology

[0002] Lubricating oil additives are an indispensable core component of modern lubricants, typically accounting for 5-30% of the finished oil. They significantly enhance the performance of base oils in various ways: anti-wear / extreme pressure agents (such as ZDDP) form a protective film, reducing friction and wear; anti-corrosion and rust inhibitors neutralize acidic substances, preventing metal corrosion and rust; detergents (sulfonates) neutralize acids, and dispersants (succinimide) suspend sludge and soot, jointly preventing deposit formation and keeping the engine / system internals clean; defoamers inhibit foam formation, pour point depressants improve low-temperature fluidity, and friction modifiers further reduce friction. Through precise formulation, these additives work synergistically to enable lubricants to effectively extend equipment life, improve operating efficiency, and adapt to harsh operating conditions (high temperature, high pressure, long cycle), meeting the stringent requirements of modern industry and transportation for high-performance lubrication. 1. Provide a broad background introduction; avoid starting with existing technologies, as this can appear too abrupt.

[0003] When processing molybdenum-bismuth additives for lubricating oils, the raw materials need to be homogenized. This is usually done using a homogenizing pump. The motor of the homogenizing pump drives the rotor to crush and disperse the raw materials. The dispersed raw materials are then returned to the hopper for circulation. However, since the raw materials need to be circulated multiple times, the flow rate of the homogenizing pump is limited, and the homogenization time is relatively long. At the same time, as the rotor rotates at high speed, the pump body temperature of the homogenizing pump rises, which may cause the raw materials to overheat. Therefore, we propose a nanoscale dispersion and homogenization device for molybdenum-bismuth additives for lubricating oils. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a nanoscale dispersion and homogenization device for molybdenum-bismuth additives in lubricating oil. The device improves the homogenization effect and accelerates the homogenization by combining physical dispersion and ultrasonic dispersion.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This nanoscale dispersion and homogenization device for molybdenum-bismuth additives in lubricating oil has the following advantages:

[0016] 1. The rotation of the rotor inside the homogenization chamber generates centrifugal force to draw in the raw material for the lubricating oil molybdenum-bismuth additive, while simultaneously generating strong shear force between the rotor and the stator. This process is accompanied by a combination of cavitation explosion, impact, and turbulence, achieving dispersion and homogenization of the raw material for the lubricating oil molybdenum-bismuth additive. Subsequently, the dispersed raw material for the lubricating oil molybdenum-bismuth additive is homogenized again by ultrasound. The combination of these two methods improves the homogenization effect.

The motor 36 is fixedly connected to the rear end of the connecting seat 32. The motor 36 outputs... The output shaft is fixedly connected to the rotating shaft of the rotor 34. The input end of the motor 36 is electrically connected to the output end of the control switch group 6. The lower end of the circulation pipe 11 and the right end of the discharge pipe 10 are both connected in series with a solenoid valve 12.

At the same time, a strong shearing force is generated between the rotor 34 and the stator 35 to disperse the additive raw material. The dispersed additive raw material enters the discharge pipe 10.

The fan 46 is located to the left of the cooler 44, and its input end is electrically connected to the control switch group 6.

The shell 33 exchanges heat with the heat transfer oil inside the volute cavity 41 to achieve cooling. The heat transfer oil is poured in from the upper connecting port 5 and poured out from the lower connecting port 5. The arc groove on the outer arc surface of the homogeneous cavity 13 increases the contact area of ​​the homogeneous cavity 13 and improves the heat dissipation effect.

[0027] The working principle of the nanoscale dispersion and homogenization device for lubricating oil molybdenum-bismuth additives provided by this utility model is as follows: The lubricating oil molybdenum-bismuth additive raw material to be processed is poured into the inside of the material tank 1. The electrical components are turned on by the control switch group 6, the external ultrasonic generator starts the ultrasonic transducer 8, and the output shaft of the motor 36 drives the rotor 34 to rotate. The additive raw material enters the housing 33 from the material tank 1. The end caps of the housing 33 seal and isolate the homogenization chamber 13 and the volute cavity 41 respectively, so the additive raw material can only enter the homogenization chamber 13. The rotor 34 generates a strong centrifugal force, which draws the additive raw material into the homogenization chamber 13. At the same time, this process is accompanied by the combined effects of cavitation explosion, impact and turbulence, which break and disperse the additive raw material. At the same time, a strong shear force is generated between the rotor 34 and the stator 35 to disperse the additive raw material. The dispersed additive raw material enters the discharge pipe 10. Due to the high speed of the rotor 34, the temperature of the housing 33 rises. 3. The heat transfer oil inside the volute cavity 41 exchanges heat to achieve cooling. The heat transfer oil is poured in from the upper connecting port 5 and poured out from the lower connecting port 5. The arc groove on the outer arc surface of the homogenizing cavity 13 increases the contact area of ​​the homogenizing cavity 13 and improves the heat dissipation effect. The heat transfer oil that absorbs the heat of the shell 33 enters the delivery pipe 42 and flows into the cooler 44 for cooling. The cooler 44 is composed of a heat dissipation plate and a serpentine pipe. The heat dissipation plate increases the heat dissipation area and the serpentine pipe increases the heat dissipation time. At the same time, the fan 46 drives the air flow to facilitate the exhaust of hot air. The cooled heat transfer oil is sent to the delivery pipe 43 by the circulation pump 45 and then returns to the volute cavity 41 to realize the circulation of the heat transfer oil. At this time, the solenoid valve 12 of the discharge pipe 10 is closed and the solenoid valve 12 of the circulation pipe 11 is opened. The dispersed additive enters the circulation pipe 11 and then enters the dispersion cylinder 7. The ultrasonic amplitude rod 9 amplifies the ultrasonic waves of the ultrasonic transducer 8 and performs homogenization operation on the additive raw materials again to improve the homogenization effect.
