Description

Technical Field

[0001] The present invention mainly relates to the technical field of lubricating oil blending production, and specifically relates to a Fischer-Tropsch synthesis long-mileage vehicle gear oil production equipment and process. Background Art

[0002] Gears are the most important transmission mechanism in machinery. They have a wide power transmission range and high transmission efficiency. They can transmit motion and power between any two axes. However, the curvature radius of gears is small, and the conditions for forming oil wedges during lubrication are poor. Each meshing of gears requires the oil film to be re-established to prevent wear. The existing new gearboxes are compact in structure and smaller in size, requiring gear oils to have higher thermal oxidation stability, higher oil film strength, better thermal conductivity and resistance to micropitting.

[0003] A high-efficiency reactor specially used for lubricating oil production and preparation described in the prior art includes a reactor shell, a controller, a stirring mechanism, an ultrasonic vibration plate and a bottom heating mechanism; the stirring mechanism includes a motor, a motor rotating shaft, a stirring bracket and a central stirring shaft, and the bottom heating mechanism includes a heating mechanism shell, and a heating tube and a heating plate are fixedly arranged on the top of the heating mechanism shell. The special stirring mechanism is arranged to extend into the reactor shell through the motor rotating shaft, the stirring bracket and the central stirring shaft to achieve mixing of the oil in the barrel.

[0004] Although the above technology can make the heating area larger, making it easier to accumulate heat, and adopts a centrally symmetrical two-row heating tube design to make both sides heated evenly and avoid uneven heating, direct heating of the lubricating oil is prone to the risk of local overheating. Overheated areas can easily cause certain additives in the lubricating oil, such as anti-wear agents and preservatives, to lose their effectiveness, thereby reducing the performance of the lubricating oil. At the same time, natural cooling is required after preparation, and the cooling speed is slow. Summary of the invention

[0019] Step 1: Add and heat the raw materials. The selected raw materials are sequentially fed into the inner shell through the feeding pipe. Then the vacuum pump and the heating coil work to feed the external air into the space between the outer shell and the inner shell. The heating coil heats the air.

[0022] In summary, the present invention mainly has the following beneficial effects: the present application starts the vacuum pump and the heating coil, and the vacuum pump draws external air into the serpentine curved pipe, and heats it through the heating coil, and then sends the high-temperature gas from the exhaust pipe into the space between the outer shell and the inner shell to heat the inner shell. As more high-temperature gas is injected, the pressure will also increase. When the pressure is greater than the elasticity of the supporting spring, the abutment ball will be pushed upward to expose the L-shaped through hole. At this time, excessive gas will be discharged from the pressure relief port, the movable groove and the L-shaped through hole, which is helpful to control the pressure in the reactor and improve the safety of operation. This indirect heating method can control the temperature more accurately, reduce the local overheating problem that may be caused by direct contact heating, and help to keep the temperature of the lubricating oil uniform, avoiding local overheating that causes additives in the lubricating oil such as anti-wear agents and preservatives to lose their effects, thereby reducing the performance of the lubricating oil.

[0023] Then the drive motor starts to work, driving the transmission shaft to rotate, so that the driving gear drives the inner shell to rotate through the meshing gear ring. At the same time, the transmission shaft will also drive the connecting shaft to rotate through the transmission wheel and the transmission chain. The connecting shaft controls the rotation of the stirring rod, so that the stirring rod and the inner shell rotate at the same time and in opposite directions. This reverse rotation stirring method can produce strong turbulence, enhance the mixing effect of the lubricating oil, and make the blending more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] All electrical components in this application are controlled by external controllers.

[0038] See also Figure 1-2As shown, a Fischer-Tropsch synthesis long-mileage automotive gear oil production device includes a blending kettle 1, a stirring rod 2, a temperature sensor 103 and a processing mechanism 3 for heating, stirring and pressure relief. The blending kettle 1 includes an outer shell 101 and an inner shell 102. The inner diameter of the outer shell 101 is larger than the outer diameter of the inner shell 102. The stirring rod 2 is vertically arranged in the inner shell 102. The top and bottom ends of the outer shell 101 are both provided with through grooves 1011. Baffles 1012 are integrally connected at the two through grooves 1011. The top and bottom ends of the inner shell 102 are respectively in contact with the end faces of the two baffles 1012 and are in a sliding manner. The temperature sensor 103 is installed on the inner wall of the outer shell 101, and a discharge pipe 1022 is connected at the center of the bottom end of the inner shell 102, and a solenoid valve 1023 is installed on the discharge pipe 1022. The top of the inner shell 102 is located on one side of the stirring rod 2 and is connected to a feeding pipe 1021. Four supporting legs 106 are evenly installed at the bottom end of the outer shell 101. Mounting blocks 7 are symmetrically welded above and below the inner wall of the outer shell 101. A ball 701 is embedded on one side of each mounting block 7 close to the inner shell 102, and each ball 701 is in contact with the outer wall of the inner shell 102 and is in rolling connection;

[0039] The processing mechanism 3 is composed of a driving component 4, a heating component 5 and a pressure relief component 6. The driving component 4 is used to control the rotation of the inner shell 102 and the stirring rod 2. The heating component 5 is used to heat the air drawn from the outside and send it into the space between the outer shell 101 and the inner shell 102. The pressure relief component 6 is used to avoid pressure changes caused by high-temperature gas in the space.

[0040] When producing Fischer-Tropsch synthesis long-mileage automotive gear oil, the staff selects the required base oil and additives according to the formula ratio, and sequentially adds them into the inner shell 102 in the blending kettle 1 through the feeding pipe 1021, and then starts the heating component 5 and the driving component 4 in the processing mechanism 3. The heating component 5 heats the extracted external air and transports the heated high-temperature gas to between the outer shell 101 and the inner shell 102 to heat the inner shell 102. During transportation, the internal pressure will increase with the increase of high-temperature gas. When the pressure intensity is greater than the abutment strength of the pressure relief component 6, the high-temperature gas will push the pressure relief component 6 to open and enter. The pressure relief operation is performed, and at this time, the driving component 4 will drive the inner shell 102 to rotate in the outer shell 101 under the action of the gear system, and the stirring rod 2 will rotate in the inner shell 102. At this time, the mounting block 7 and the ball 701 can support the rotating inner shell 102 to prevent the inner shell 102 from displacement, and the rotation directions of the two are opposite. The base oil and the additive are heated and mixed. After a period of time, the composite defoamer and the pour point depressant are added to the mixed oil through the feeding pipe 1021, and heated and mixed to form a uniform gear oil. Finally, the solenoid valve 1023 is opened to discharge the gear oil through the discharge pipe 1022;

[0041] Therefore, the indirect heating method adopted in the present application can control the temperature more accurately, reduce the local overheating problem that may be caused by direct contact heating, and help maintain the uniform temperature of the lubricating oil, avoiding local overheating that causes additives in the lubricating oil such as anti-wear agents, preservatives, etc. to lose their effectiveness, thereby reducing the performance of the lubricating oil; at the same time, the reverse rotating stirring method can produce stronger turbulence, enhance the mixing effect of the lubricating oil, and make the blending more uniform.

[0044] The vacuum pump 502 and the heating coil 504 work, and the vacuum pump 502 extracts the external air through the vacuum pipe 5022 and the serpentine elbow 503. The dust contained in the extracted air is filtered out by the filter plate 5032 to ensure the quality of the air. At the same time, the dust cover 5031 can be rotated to separate it from the serpentine elbow 503, and the filter plate 5032 can be replaced or cleaned. The extracted air is heated by the heating coil 504 when passing through the serpentine elbow 503.

At this time, the temperature sensor 103 with the model GDHT-20 detects the temperature of the air in real time to ensure that the heating temperature is between 55-65°C;

[0045] As the high-temperature air enters, the pressure will also increase. When the pressure is greater than the elasticity of the supporting spring 6031, the abutment ball 603 will be pushed upward, and the upward abutment ball 603 will squeeze the supporting spring 6031. The abutment ball 603 moves along the movable groove 602 to expose the L-shaped through hole 604. At this time, the high-temperature air will be discharged through the pressure relief port 104, the movable groove 602 and the L-shaped through hole 604 to achieve a pressure relief operation.

[0049] See also Figure 1-10 As shown, according to the above embodiment, a process for producing a Fischer-Tropsch synthesis long-mileage vehicle gear oil production device is also provided, comprising the following steps:

[0050] Step 1, adding and heating raw materials, the selected raw materials are sequentially fed into the inner shell 102 through the feeding pipe 1021, and then the vacuum pump 502 and the heating coil 504 work to feed the external air into the space between the outer shell 101 and the inner shell 102, and the heating coil 504 heats the air, and the high-temperature air heats the inner shell 102 to raise its temperature to 55-65°C, and the temperature sensor 103 monitors the temperature value in real time; wherein the raw materials in this step are all raw materials and proportions used in a long-mileage automotive gear oil and a preparation method thereof in the prior art;

The extracted air is heated by the heating coil 504 when passing through the serpentine bend 503. The heated air enters the space between the outer shell 101 and the inner shell 102 through the exhaust pipe 5021, and the inner shell 102 is evenly heated.

After a period of time, the composite defoamer and pour point depressant are added to the mixed oil through the feeding pipe 1021, and heated and mixed to form a uniform gear oil. Finally, the solenoid valve 1023 is opened to discharge the gear oil through the discharge pipe 1022.
