Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and specifically to a reaction kettle for lubricating oil additives. Background Art

[0002] A reaction kettle for lubricating oil additives is a device used to react, transform or mix raw materials and generate lubricating oil additives. Lubricating oil additives refer to chemicals added to base lubricating oils to improve the performance and function of the lubricating oils.

[0003] In the workshop for producing chemical products, when lubricating oil additives are generated in the reaction kettle, since the lubricating oil additives are high-viscosity lubricating oil additives, the lubricating oil additives are prone to accumulate at the dead zone positions of the baffles during the reaction, resulting in inability to flow, and causing uneven mixing of the lubricating oil additives during the reaction process. At the same time, the dead zone positions are not conducive to cleaning.

[0004] In order to ensure sufficient stirring of the lubricating oil additives, some rods or plates are provided on the inner wall of the reaction kettle, so that the lubricating oil additives can flow along a certain direction under the action of the stirring rods. However, the stirring dead zones caused by the stirring rods or plates hinder the flow and mixing of the lubricating oil additives, resulting in the accumulation of reactants at the positions of the stirring dead zones. At this time, some lubricating oil additives will not flow even during stirring, and the lubricating oil additives are unevenly mixed during the reaction process, which is likely to cause instability of the product, resulting in changes in its performance during use, and thus affecting the performance and quality of the lubricating oil additives. At the same time, during the reaction process, the stirring dead zones will cause uneven temperature distribution, generating a temperature gradient, resulting in a lower reaction rate in the dead zone area and a higher reaction rate in other areas, thereby leading to inconsistent degrees of reaction intensity, and thus affecting the reaction yield and efficiency.

[0005] In the prior art, one end of a vertical baffle is fixedly connected to the pipe orifice of the upper head of the reaction kettle through a flange, and the other end is inserted into the lubricating oil additives inside the equipment. During the generation of the lubricating oil additives in the reaction kettle, the viscosity of the lubricating oil additives in the reaction kettle increases as the reaction progresses. However, when the liquid in the reaction kettle flows to the vertical baffle, a laminar flow effect will be generated, thereby restricting the lateral movement of the fluid, and it is easy to have the problem of uneven mixing of the lubricating oil additives in the reaction kettle during the reaction process.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs a reaction kettle for lubricating oil additives, which solves the above technical problems. Summary of the Invention

[0007] The object of the present invention is to provide a reaction kettle for lubricating oil additives. In order to solve the problem that when the liquid in the reaction kettle flows to the vertical baffle, a laminar flow effect will be generated, which will limit the lateral movement of the fluid, and the lubricating oil additives in the reaction kettle are prone to uneven mixing during the reaction process. By means of reciprocating swinging, the distribution of shear force in the reaction kettle is changed and the turbulent flow effect of the fluid is improved, so as to achieve uniform mixing of the lubricating oil additives in the reaction kettle.

[0008] A reaction kettle for lubricating oil additives includes a kettle body and a stirrer, and also includes a stirrer, an opening and closing component, a swinging component and a vertical baffle. The stirrer is installed inside the kettle body. The vertical baffle is connected to the kettle body. A swinging component is installed below the vertical baffle. The swinging component moves in the same frequency as the vertical baffle to achieve uniform distribution of the lubricating oil additives. An opening and closing component is installed below the swinging component. The opening and closing component separates the flow area of the lubricating oil additives through the swinging of the vertical baffle.

[0009] When the motor rotates forward, the vertical baffle swings forward in the reaction kettle. When the viscosity in the reaction kettle reaches a predetermined value, the motor in the reaction kettle rotates in the reverse direction. While the motor rotates, it drives the ratchet to rotate. While the ratchet rotates, it drives the pawl to rotate. When the vertical baffle swings, the vertical baffle plays a guiding role in the eddy current formed by the stirrer, preventing the movement path of the eddy current from being disordered. At the same time, the lubricating oil additives in the reaction kettle are uniformly mixed. The vertical baffle and the inner wall of the kettle body are connected by a spring. When the vertical baffle swings, the spring restores the vertical baffle to its original position. At the same time, during the swinging process of the vertical baffle, the spring prevents the vertical baffle from hitting the inner wall of the reaction kettle, causing the path of the liquid inside the reaction kettle to change and the temperature distribution in the reaction kettle to change.

[0010] A support is installed at the bottom of the kettle body, and a shock-absorbing spring is installed on the inner wall of the support. The shock-absorbing spring reduces the vibration caused by the reactor during the rotation of the agitator. At the same time, a fixing frame is installed on the side wall of the kettle body, so that when the reactor is installed, the reactor is installed on the wall, making the installation of the reactor convenient. A swing assembly is installed below the vertical baffle. The swing assembly moves in the same frequency as the vertical baffle to achieve uniform distribution of the lubricating oil additive. The swing assembly moves under the action of the agitator, and the stirring blades in the swing assembly swing. When the viscosity of the lubricating oil additive in the reactor increases, the stirring blades in the swing assembly and the agitator rotate simultaneously, so that the lubricating oil additive is evenly mixed when it rotates. An opening and closing assembly is installed below the swing assembly. The opening and closing assembly separates the flow area of the lubricating oil additive through the swing of the vertical baffle. Driven by the ratchet, the vertical baffle moves, causing the transverse baffle in the opening and closing assembly to extend. The transverse baffle separates the lubricating oil additive in the reactor, so that the lubricating oil additive forms a flow partition during the reaction. At the same time, when the transverse baffle extends, the transverse baffle will prevent the direct rotation of the liquid, so that the transverse baffle forms convection and disturbance in different areas, increasing the mixing and contact between the liquids in the reactor during the reaction.

[0011] The swing assembly includes a pawl, a ratchet, a fixed block, stirring blades and a spiral convex block. The pawl is installed at the bottom of the vertical baffle. The ratchet is installed below the agitator. The fixed block is installed at the bottom of the ratchet. The stirring blades are obliquely arranged and installed on the side wall of the fixed block. The spiral convex block is installed below the pawl. The spiral convex block eliminates the dead zone area of the diversion zone formed during the telescopic process of the transverse baffle by guiding the flow of the lubricating oil additive. The spiral convex block guides the contact between the lubricating oil additive and the bottom end of the spiral convex block during the swinging process. The spiral protrusion prevents the material from staying in the diversion zone during the flow. At the same time, during the movement of the spiral protrusion, the flow path and speed of the lubricating oil additive in the diversion zone are changed, so that the spiral convex block introduces turbulence during the movement, promoting the mixing and reaction of the lubricating oil additive. The agitator is rotationally connected to the ratchet, and the fixed block is fixedly installed at the bottom of the ratchet. The stirring blades are fixedly installed on both sides of the fixed block;

[0012] When the motor rotates forward, the ratchet rotates forward. At this time, the stirrer rotates forward synchronously, and the stirrer stirs and mixes the lubricating oil additive, so that the lubricating oil additive reacts evenly during the stirring and mixing process. At the same time, the forward-moving ratchet will drive the pawl to deflect inward, and the stirring blade fixedly connected to the bottom of the ratchet rotates forward. At this time, the stirring blade will drive the lubricating oil additive toward the bottom center, bringing the lubricating oil additive at the top from the upper end to the lower end. At the same time, the vertical baffle will swing inward, and then change the flow direction of the lubricating oil additive under the condition of generating disturbance, so that the lubricating oil additive can fill the inside of the kettle body during forward rotation. During forward extrusion, the flat surface of the ratchet squeezes the pawl, thereby driving the spiral convex block and the vertical baffle to rotate forward. At this time, the lubricating oil additive will gather toward the center along the arc surface of the vertical baffle. At the same time, in cooperation with the forward-rotating stirring blade, it further improves the gathering of the lubricating oil additive toward the middle and lower part, changing the flow direction of the lubricating oil additive.

[0013] When the motor rotates in reverse, while the stirrer rotates, the ratchet rotates in reverse. Different from the forward rotation, because the rotation direction of the ratchet is different, the surface that drives the ratchet to squeeze the pawl is different. During reverse extrusion, the arc surface of the ratchet squeezes the pawl, thereby driving the spiral convex block and the vertical baffle to rotate in reverse. At this time, the lubricating oil additive will spread outward along the arc surface of the vertical baffle. At the same time, in cooperation with the reversely rotating stirring blade, it further makes the lubricating oil additive move centrifugally outward, changing the flow direction of the lubricating oil additive.

[0014] The stirring blade fixedly connected to the bottom of the ratchet rotates. When the stirring blade rotates, the stirrer forms a convection effect with the stirring blade at the top during stirring, so that the lubricating oil additive is evenly mixed in the reaction kettle. The stirring blade is obliquely arranged on the fixed block. The combination of the obliquely arranged stirring blade and the paddle stirrer realizes the shearing effect in multiple directions. When the paddle stirrer and the obliquely arranged stirring blade rotate, a shearing force will be generated. The shearing force will shear the agglomerates formed by the reactants put into the reaction kettle and break up the agglomerates formed in the reaction kettle. At the same time, the shearing force shears the lubricating oil additive in the reaction, so that the reactants are evenly mixed during the reaction process. At the same time, the paddle stirrer forms a convection effect, moving the reactants upward from the bottom during stirring, and the stirring blade obliquely arranged at the top moves the lubricating oil additive at the top downward from the upper part. At the same time, the generated convection effect brings the reactants into the stirring area from different positions, so that the lubricating oil additive is brought into the stirring area from different positions. When the lubricating oil additive is stirred, the lubricating oil additive with the generated convection effect evenly mixes the lubricating oil additive.

[0015] The opening and closing assembly includes a rotating disk, a moving groove, a connecting rod, a fixed disk, a fixed rod, a transverse baffle, and a moving rod. The fixed disk is fixedly installed on the inner wall of the reactor. A connecting rod is fixedly installed on the upper side of the fixed disk, and the connecting rods are arranged annularly on the fixed disk. A rotating disk is rotatably installed on the upper side of the fixed disk. A moving groove is formed in the rotating disk, and a fixed rod is installed on the rotating disk. When the motor rotates in the reverse direction, the motor drives the stirrer to rotate, and the stirrer stirs the lubricating oil additive. At the same time, the motor drives the ratchet to rotate. While the ratchet rotates, it drives the pawl to rotate. While the pawl moves, it drives the fixed rod to move. While the fixed rod moves, the rotating disk rotates, thereby realizing the extension of the transverse baffle. At the same time, a retraction spring is installed on the fixed rod. Under the action of the retraction spring, the fixed rod returns to its original position, realizing the expansion and contraction of the transverse baffle, changing the flow direction of the fluid in the reactor. A moving rod is installed at the bottom of the transverse baffle, and the moving rod is slidably connected to the moving groove. One end of the transverse baffle away from the stirrer is pointed. The transverse baffle changes the flow velocity of the fluid through the pointed shape to realize the uniform stirring of the lubricating oil additive by the stirrer. The pointed baffle enhances the shear and disturbance of the fluid in the reactor, and at the same time improves the suspended particles in the reactants, changing the fluid velocity in the reactor, interacting with the stirring of the stirrer, and enabling the stirrer to uniformly stir the lubricating oil additive. The transverse baffle changes the shear layer inside the reactor body by the swing of the vertical baffle to realize the uniform distribution of the shear force inside the reactor body. While the vertical baffle swings, it changes the shear layer inside the reactor body. At the same time, the transverse baffle performs a reciprocating transverse movement under the action of the fixed rod. The transverse baffle changes the shear layer of the fluid at the bottom, and at the same time increases the disturbance at the bottom when the transverse baffle moves at the bottom. When the vertical baffle moves at the top of the reactor, it increases the disturbance at the top. The bottom disturbance and top disturbance in the reactor make the shear force of the fluid in the reactor evenly dispersed, thereby realizing the uniform mixing of the lubricating oil additive.

[0016] Jagged grooves are formed on the shaft of the stirrer. The stirrer adjusts the fluid flow intensity around the transverse baffle through the jagged grooves, thereby realizing the stirring of the lubricating oil additive. When the motor rotates in the reverse direction, the motor drives the stirrer to stir. When the lubricating oil additive is put into the reactor, the jagged grooves formed on the stirrer will bring in the lubricating oil additive, causing the fluid in the reactor to be disturbed. Then, under the condition of disturbance, the flow direction of the lubricating oil additive is changed. The shear force generated by the transverse baffle on the fluid is evenly distributed in the expanded and contracted state, making the lubricating oil additive uniformly mixed in the reactor. When the motor rotates forward, the stirrer rotates, and the grooves formed on the stirrer change the flow characteristics around the stirrer. The jagged grooves will break the laminar flow state when rotating, causing a turbulent flow effect when the stirrer stirs, thereby realizing the uniform mixing of the lubricating oil additive in the reactor.

[0017] Vertical baffles are symmetrically installed on both sides of the agitator. The side of the vertical baffle close to the agitator is curved. The vertical baffle guides the flow of the eddy current formed by the agitator through the curved shape. When the agitator stirs and mixes the lubricating oil additive, an eddy current will be formed. The vertical baffle will guide the flow of the eddy current through the curved shape to avoid the chaos and disorder of the eddy current. When the viscosity of the lubricating oil additive in the reaction kettle increases to a predetermined value, the motor starts to rotate and drives the ratchet to rotate. The ratchet and the pawl cooperate in motion, and the vertical baffle fixedly installed on the upper side of the pawl starts to swing. During the swinging process of the vertical baffle, the curved baffle will form an eddy current. When the viscous lubricating oil additive passes through the curved part of the vertical baffle, the eddy current generated by the curved part of the vertical baffle will drive the viscous lubricating oil additive to move, avoiding uneven mixing of the lubricating oil additive during the reaction. At the same time, during the swinging process of the vertical baffle, the distribution of the flow field and the shear force in the reaction kettle will be changed, thereby generating turbulence, so that the lubricating oil additive in the reaction kettle is uniformly mixed under the combined action of the agitator and the vertical baffle.

[0018] The width of the left end of the vertical baffle is greater than that of the right end. The vertical baffle introduces turbulent and laminar disturbances of the fluid through the difference in the lengths of both ends to achieve uniform mixing of the lubricating oil additive. The narrow end of the vertical baffle restricts the flow range of the fluid and increases the shear force during the mixing of the lubricating oil additive. At the same time, the wide end of the vertical baffle provides a flow space, enabling the fluid to diffuse from the narrow-side turbulent region to the wide-side laminar region, making the lubricating oil additive uniformly mixed. At the same time, under the rotation of the ratchet, the vertical baffle is driven to swing. During the process of adding the lubricating oil additive to the reaction kettle to form the lubricating oil additive, the viscosity of the fluid in the reaction kettle increases. During the swinging process of the vertical baffle, an additional stirring force and shear force are provided for the mixing of the lubricating oil additive, thereby increasing the reaction rate of the lubricating oil additive. At the same time, when the viscosity of the lubricating oil additive in the reaction kettle increases to a predetermined value, the motor starts to rotate and drives the ratchet to rotate. The ratchet and the pawl cooperate in motion, and the vertical baffle fixedly installed on the upper side of the pawl starts to swing. During the swinging process of the vertical baffle, an asymmetric flow field will be formed, and the vertical baffle will provide different shear rates for the lubricating oil additive during the flowing process, thereby promoting the mixing and agitation of the lubricating oil additive.

[0019] The root length of the stirring blade is greater than the tip length. The stirring blade forms a shearing effect through the difference between the root length and the tip length to disperse the agglomerates formed by the lubricating oil additive. When the ratchet rotates, it drives the stirring blade to rotate. The asymmetrical shape of the stirring blade creates a shearing effect between the root and the tip of the stirring blade. The shearing effect destroys the agglomerates formed when the lubricating oil additive is put into the reaction kettle, enabling the lubricating oil additive to be evenly mixed and dispersed under the combined action of the stirring blade and the stirrer. At the same time, the greater length of the root than the tip enhances the intensity of the turbulence. The turbulence formed when the stirring blade stirs makes the lubricating oil additives mix evenly. Meanwhile, through holes are provided on the stirring blade, and the through holes are radially distributed in the reverse direction from the root to the tip of the stirring blade, promoting the mutual contact and mixing of the lubricating oil additives and enabling the lubricating oil additives to react evenly.

[0020] A vertical baffle is fixedly installed on the upper side of the ratchet pawl. A circulation hole is provided at the top of the vertical baffle. A fixing hole is provided on the ratchet pawl. When the vertical baffle swings, the circulation hole provided on the vertical baffle and the fixing hole provided on the ratchet pawl are on the same axis. The vertical baffle realizes the uniform transmission of the stirring force through the circulation hole and the fixing hole being on the same axis. When the motor rotates in the reverse direction, the circulation hole provided on the vertical baffle and the fixing hole provided on the ratchet pawl are on the same axis. The vertical baffle transmits the stirring force to the fixing hole provided on the ratchet pawl through the circulation hole, and transfers the stirring force to the lubricating oil additive during the movement of the vertical baffle, thereby realizing the uniform mixing of the lubricating oil additive. At the same time, the viscosity of the lubricating oil additive increases during the reaction process, and the stirring force evenly transfers the heat in the lubricating oil additive, preventing the uneven temperature distribution of the lubricating oil additive in the reaction kettle and thus affecting the formation of the lubricating oil additive.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. For a reaction kettle for lubricating oil additives provided by the present invention, when the motor rotates forward, the ratchet rotates forward. At this time, the stirrer rotates forward synchronously, and the stirrer stirs and mixes the lubricating oil additive, enabling the lubricating oil additive to react evenly during the stirring and mixing process. At the same time, the forward-moving ratchet drives the ratchet pawl to shift inward. The stirring blade fixedly connected to the bottom of the ratchet rotates forward. At this time, the stirring blade drives the lubricating oil additive towards the bottom center, bringing the lubricating oil additive at the top from the upper end to the lower end. Meanwhile, the vertical baffle swings inward, thereby changing the flow direction of the lubricating oil additive under the condition of generating disturbance, enabling the lubricating oil additive to fill the inside of the kettle body during forward rotation.

[0023] 2. A reaction kettle for lubricating oil additives provided by the present invention. When extruding forward, it is the flat surface of the ratchet that extrudes the pawl, thereby driving the spiral convex block and the vertical baffle to rotate forward. At this time, the lubricating oil additives will gather towards the center along the arc surface of the vertical baffle. At the same time, cooperating with the stirring blade rotating forward, it further improves the gathering of the lubricating oil additives towards the middle and lower part, changing the flow direction of the lubricating oil additives; when extruding backward, it is the arc surface of the ratchet that extrudes the pawl, thereby driving the spiral convex block and the vertical baffle to rotate backward. At this time, the lubricating oil additives will diffuse outward along the arc surface of the vertical baffle. At the same time, cooperating with the stirring blade rotating backward, it further makes the lubricating oil additives move centrifugally outward, changing the flow direction of the lubricating oil additives.

[0034] Such as Figures 1 to 5As shown, a reactor for lubricating oil additives includes a reactor body 1 and a stirrer 2, and also includes a vertical baffle 5, a swing assembly 4 and an opening and closing assembly 3. A stirrer 2 is installed inside the reactor body 1, and a vertical baffle 5 is installed near the stirrer 2. When the motor 11 rotates forward, the vertical baffle 5 swings forward in the reactor. When the viscosity in the reactor reaches a predetermined value, the motor 11 in the reactor rotates in reverse. While the motor 11 rotates, it drives the ratchet 42 to rotate. While the ratchet 42 rotates, it drives the pawl 41 to rotate. When the vertical baffle 5 swings, the vertical baffle 5 plays a guiding role in the eddy current formed by the stirrer 2, preventing the movement path of the eddy current from being disordered. At the same time, the lubricating oil additives in the reactor are evenly mixed. The vertical baffle 5 is connected to the inner wall of the reactor body 1 by a spring. When the vertical baffle 5 swings, the spring restores the vertical baffle 5 to its original position. At the same time, during the swinging process of the vertical baffle 5, the spring prevents the vertical baffle 5 from hitting the inner wall of the reactor, causing the path of the liquid inside the reactor to change and the temperature distribution in the reactor to change; a support 12 is installed at the bottom of the reactor body 1, and a shock-absorbing spring is installed on the inner wall of the support 12. The shock-absorbing spring reduces the vibration caused by the reactor when the stirrer 2 rotates. At the same time, a fixing frame is installed on the side wall of the reactor body 1, so that when the reactor is installed, the reactor is installed on the wall, making the installation of the reactor convenient. A swing assembly 4 is installed below the vertical baffle 5. The swing assembly 4 moves in the same frequency as the vertical baffle 5 to achieve uniform distribution of the lubricating oil additives. The swing assembly 4 moves under the action of the stirrer 2, and the stirring blades 44 in the swing assembly 4 swing. When the viscosity of the lubricating oil additives in the reactor increases, the stirring blades 44 in the swing assembly 4 and the stirrer 2 rotate simultaneously, so that the lubricating oil additives are evenly mixed when rotating. An opening and closing assembly 3 is installed below the swing assembly 4. The opening and closing assembly 3 divides the flow area of the lubricating oil additives through the swing of the vertical baffle 5. Driven by the ratchet 42, the vertical baffle 5 moves, causing the transverse baffle 36 in the opening and closing assembly 3 to extend. The transverse baffle 36 divides the lubricating oil additives in the reactor, so that the lubricating oil additives form a flow partition during the reaction. At the same time, during the extension process of the transverse baffle 36, the transverse baffle 36 will prevent the direct rotation of the liquid, so that the transverse baffle 36 forms convection and disturbance in different areas, increasing the mixing and contact between the liquids in the reactor during the reaction.

[0035] As Figure 7As shown, the swing assembly 4 includes a pawl 41, a ratchet 42, a fixed block 43, a stirring blade 44 and a spiral bump 45. The pawl 41 is fixedly installed at the middle position of the bottom of the vertical baffle 5. The spiral bump 45 is installed at the bottom of the pawl 41. The bottom of the spiral bump 45 is installed with a transverse baffle 36. The spiral bump 45 eliminates the dead zone in the diversion area formed during the telescopic process of the transverse baffle 36 by guiding the flow of the lubricating oil additive. The spiral bump guides the contact between the lubricating oil additive and the bottom end of the spiral bump 45 during the swinging process. The spiral protrusion prevents the material from staying in the diversion area during the flow. At the same time, during the movement of the spiral protrusion, it changes the flow path and speed of the lubricating oil additive in the diversion area, so that the spiral bump introduces turbulence during the movement, promoting the mixing and reaction of the lubricating oil additive. The stirrer 2 is rotatably connected to the ratchet 42. The fixed block 43 is fixedly installed at the bottom of the ratchet 42. The stirring blades 44 are fixedly installed on both sides of the fixed block 43;

[0036] When the motor 11 rotates forward, the ratchet 42 rotates forward. At this time, the stirrer 2 rotates forward synchronously. The stirrer 2 stirs and mixes the lubricating oil additive, so that the lubricating oil additive reacts evenly during the stirring and mixing process; at the same time, the forward moving ratchet 42 will drive the pawl 41 to deflect inward. The stirring blade 44 fixedly connected to the bottom of the ratchet 42 rotates forward. At this time, the stirring blade 44 will drive the lubricating oil additive towards the bottom center, bringing the lubricating oil additive at the top from the upper end to the lower end. At the same time, the vertical baffle 5 will swing inward, thereby changing the flow direction of the lubricating oil additive under the condition of generating disturbance, so that the lubricating oil additive can fill the inside of the kettle body 1 during forward rotation; during forward extrusion, the flat surface of the ratchet 42 presses the pawl 41, thereby driving the spiral bump 45 and the vertical baffle 5 to rotate forward. At this time, the lubricating oil additive will gather towards the center along the arc surface of the vertical baffle 5. At the same time, cooperating with the forward rotating stirring blade 44, it further improves the gathering of the lubricating oil additive towards the middle and lower part, changing the flow direction of the lubricating oil additive;

[0037] When the motor 11 rotates in the reverse direction, while the stirrer 2 rotates, the ratchet 42 rotates in the reverse direction. Different from the forward rotation, due to the different rotation directions of the ratchet 42, the surface of the ratchet 42 pressing the pawl 41 is different. During reverse extrusion, the arc surface of the ratchet 42 presses the pawl 41, thereby driving the spiral bump 45 and the vertical baffle 5 to rotate in the reverse direction. At this time, the lubricating oil additive will diffuse outward along the arc surface of the vertical baffle 5. At the same time, cooperating with the reverse rotating stirring blade 44, it further makes the lubricating oil additive move centrifugally outward, changing the flow direction of the lubricating oil additive;

[0038] The stirring blade 44 fixedly connected to the bottom of the ratchet 42 rotates. When the stirring blade 44 rotates, a convection effect is formed between the stirrer 2 and the top stirring blade 44 during stirring, enabling the lubricating oil additive to be evenly mixed in the reaction kettle. The stirring blade 44 is obliquely arranged on the fixed block 43. The combination of the obliquely arranged stirring blade 44 and the paddle stirrer 2 achieves a shearing effect in multiple directions. When the paddle stirrer 2 and the obliquely arranged stirring blade 44 rotate, a shearing force is generated. The shearing force shears the lumps formed when the reactants are put into the reaction kettle, breaks up the lumps formed in the reaction kettle, and at the same time, the shearing force shears the lubricating oil additive in the reaction, enabling the reactants to be evenly mixed during the reaction process. At the same time, the paddle stirrer 2 forms a convection effect, moving the reactants from the bottom upwards during stirring, and the obliquely arranged stirring blade 44 at the top moves the lubricating oil additive at the top from the upper part downwards. The simultaneously generated convection effect brings the reactants into the stirring area from different positions, enabling the lubricating oil additive to be brought into the stirring area from different positions. When the lubricating oil additive is stirred, the lubricating oil additive with the generated convection effect evenly mixes the lubricating oil additive.

[0039] Such as Figure 6As shown in the figure, the opening and closing assembly 3 includes a rotating disk 31, a moving groove 32, a connecting rod 33, a fixed disk 34, a fixed rod 35, a transverse baffle 36 and a moving rod 37. The fixed disk 34 is fixedly installed on the inner wall of the reaction kettle. A connecting rod 33 is fixedly installed on the upper side of the fixed disk 34. The connecting rods 33 are arranged annularly on the fixed disk 34. A rotating disk 31 is rotatably installed on the upper side of the fixed disk 34. A moving groove 32 is formed on the rotating disk 31. A fixed rod 35 is installed on the rotating disk 31. When the motor 11 rotates in the reverse direction, the motor 11 drives the stirrer 2 to rotate. The stirrer 2 stirs the lubricating oil additive. At the same time, the ratchet 42 is driven to rotate. When the ratchet 42 rotates, the pawl 41 is driven to rotate. When the pawl 41 moves, the fixed rod 35 is driven to move. When the fixed rod 35 moves, the rotating disk 31 rotates, thereby realizing the extension of the transverse baffle 36. At the same time, a retraction spring is installed on the fixed rod 35. Under the action of the retraction spring, the fixed rod 35 returns to its original position, realizing the expansion and contraction of the transverse baffle 36, changing the flow direction of the fluid in the reaction kettle. A moving rod 37 is installed at the bottom of the transverse baffle 36. The moving rod 37 is slidably connected with the moving groove 32. One end of the transverse baffle 36 away from the stirrer 2 is set to be pointed 361. The transverse baffle 36 with the pointed 361 changes the flow velocity of the fluid to realize the uniform stirring of the lubricating oil additive by the stirrer 2. The transverse baffle 36 with the pointed 361 enhances the shear and disturbance of the fluid in the reaction kettle, and at the same time improves the suspended particles in the reactants, changing the fluid velocity in the reaction kettle, interacting with the stirring of the stirrer 2, so that the stirrer 2 uniformly stirs the lubricating oil additive. The transverse baffle 36 changes the shear layer inside the kettle body 1 by the swing of the vertical baffle 5 to realize the uniform distribution of the shear force inside the kettle body 1. When the vertical baffle 5 swings, the shear layer inside the kettle body 1 is changed. At the same time, the transverse baffle 36 makes a reciprocating transverse movement under the action of the fixed rod 35. The transverse baffle 36 changes the shear layer of the fluid at the bottom. At the same time, when the transverse baffle 36 moves at the bottom, the disturbance at the bottom is increased. When the vertical baffle 5 moves at the top of the reaction kettle, the disturbance at the top is increased. The disturbance at the bottom and the top in the reaction kettle make the shear force of the fluid in the reaction kettle evenly dispersed, thereby realizing the uniform mixing of the lubricating oil additive.

[0040] One end of the vertical baffle 5 has a greater width than the other end. The vertical baffle 5 introduces turbulent and laminar disturbances of the fluid through the difference in the lengths of the two ends to achieve uniform mixing of the lubricating oil additive. The narrow end of the vertical baffle 5 restricts the flow range of the fluid, increasing the shear force during the mixing of the lubricating oil additive. At the same time, the wide end of the vertical baffle 5 provides a flow space, enabling the fluid to diffuse from the narrow-side turbulent region to the wide-side laminar region, making the mixing of the lubricating oil additive uniform. At the same time, driven by the rotation of the ratchet 42, the vertical baffle 5 swings. During the process of adding the lubricating oil additive to the reaction kettle to form the lubricating oil additive, the viscosity of the fluid in the reaction kettle increases. During the swinging process of the vertical baffle 5, it provides additional stirring force and shear force for the mixing of the lubricating oil additive, thereby increasing the reaction rate of the lubricating oil additive. At the same time, when the viscosity of the lubricating oil additive in the reaction kettle increases to a predetermined value, the motor 11 starts to rotate, driving the ratchet 42 to rotate. The ratchet 42 cooperates with the pawl 41 in motion. The vertical baffle 5 fixedly installed on the upper side of the pawl 41 starts to swing. During the swinging process of the vertical baffle 5, the vertical baffle 5 forms an asymmetric flow field. During the flow of the lubricating oil additive, the vertical baffle 5 provides different shear rates for the lubricating oil additive, thereby promoting the mixing and stirring of the lubricating oil additive.

[0041] Jagged grooves 21 are provided on the shaft of the stirrer 2. The stirrer 2 adjusts the fluid flow intensity around the transverse baffle 36 through the jagged grooves 21, thereby stirring the lubricating oil additive. When the motor 11 rotates in the reverse direction, the motor 11 drives the stirrer 2 to stir. When the lubricating oil additive is put into the reaction kettle, the jagged grooves provided on the stirrer 2 will bring in the lubricating oil additive, causing disturbances in the fluid in the reaction kettle. Then, under the condition of generating disturbances, the flow direction of the lubricating oil additive is changed. The shear force generated by the transverse baffle 36 on the fluid is evenly distributed in the telescopic state, making the lubricating oil additive mix evenly in the reaction kettle. When the motor 11 rotates forward, the stirrer 2 rotates. The grooves provided on the stirrer 2 change the flow characteristics around the stirrer 2. The jagged grooves break the laminar state when rotating, enabling the stirrer 2 to strengthen the turbulent effect during stirring, thereby achieving uniform mixing of the lubricating oil additive in the reaction kettle.

[0042] The left end of the vertical baffle 5 is wider than the right end. The vertical baffle 5 introduces turbulent and laminar disturbances of the fluid through the difference in the lengths of both ends to achieve uniform mixing of the lubricating oil additive. The narrow end of the vertical baffle 5 restricts the flow range of the fluid, increasing the shear force during the mixing of the lubricating oil additive. At the same time, the wide end of the vertical baffle 5 provides a flow space, enabling the fluid to diffuse from the narrow-side turbulent region to the wide-side laminar region, making the mixing of the lubricating oil additive uniform. Meanwhile, driven by the rotation of the ratchet 42, the vertical baffle 5 swings. During the process of adding the lubricating oil additive to the reaction kettle to form the lubricating oil additive, the viscosity of the fluid in the reaction kettle increases. During the swinging process of the vertical baffle 5, it provides additional stirring force and shear force for the mixing of the lubricating oil additive, thereby increasing the reaction rate of the lubricating oil additive. At the same time, when the viscosity of the lubricating oil additive in the reaction kettle increases to a predetermined value, the motor 11 starts to rotate, driving the ratchet 42 to rotate. The ratchet 42 and the pawl 41 cooperate in motion. The vertical baffle 5 fixedly installed on the upper side of the pawl 41 starts to swing. During the swinging process of the vertical baffle 5, the narrow-side part of the vertical baffle 5 restricts the flow of the viscous lubricating oil additive, and the wide-side part of the vertical baffle 5 limits the range of the eddy current.

[0043] As Figure 8 shown, the shape of the stirring blade 44 is spiral, and the side in the rotation direction of the stirring blade 44 is a concave surface.

[0044] When the stirring blade 44 rotates forward, it will drive the lubricating oil additive to move downward in a spiral manner, and at the same time, it will push the lubricating oil additive toward the center. When the stirring blade 44 rotates in reverse, it will drive the lubricating oil additive to move upward in a spiral manner, and it will drive the lubricating oil additive to move outward, and then mix with the lubricating oil additive above, improving the uniformity.

[0045] The length of the blade root 441 of the stirring blade 44 is greater than the length of the blade tip 442. The stirring blade 44 forms a shear effect through the difference between the length of the blade root 441 and the length of the blade tip 442 to disperse the agglomerates formed by the lubricating oil additive. When the ratchet 42 rotates, it drives the stirring blade 44 to rotate. The asymmetrical shape of the stirring blade 44 causes a shear effect between the blade root 441 and the blade tip 442 of the stirring blade 44. The shear effect acts on the agglomerates formed when the lubricating oil additive is put into the reaction kettle, and the agglomerates are destroyed under the action of the shear effect, enabling the lubricating oil additive to be uniformly mixed and dispersed under the combined action of the stirring blade 44 and the stirrer 2. At the same time, the length of the blade root 441 being greater than the length of the blade tip 442 enhances the intensity of the turbulence. The turbulence formed when the stirring blade 44 stirs makes the mixing between the lubricating oil additives uniform. At the same time, through holes are opened on the stirring blade 44, and the through holes are radially distributed along the reverse direction from the blade root 441 to the blade tip 442 of the stirring blade 44, promoting the mutual contact and mixing between the lubricating oil additives, enabling the lubricating oil additives to react uniformly.

[0046] A vertical baffle 5 is fixedly installed on the upper side of the pawl 41. A circulation hole 51 is opened at the top of the vertical baffle 5. A fixing hole 411 is opened on the pawl 41. When the vertical baffle 5 swings, the circulation hole 51 opened on the vertical baffle 5 and the fixing hole 411 opened on the pawl 41 are on the same axis. The vertical baffle 5 realizes uniform transmission of the stirring force through the circulation hole 51 and the fixing hole 411 being on the same axis. When the motor 11 rotates in the reverse direction, the circulation hole 51 opened on the vertical baffle 5 and the fixing hole 411 opened on the pawl 41 are on the same axis. The vertical baffle 5 transmits the stirring force to the fixing hole 411 opened on the pawl 41 through the circulation hole 51. During the movement of the vertical baffle 5, the stirring force is transmitted to the lubricating oil additive, thereby realizing uniform mixing of the lubricating oil additive. At the same time, the viscosity of the lubricating oil additive increases during the reaction process, and the stirring force evenly transmits the heat in the lubricating oil additive, preventing uneven temperature distribution of the lubricating oil additive in the reaction kettle and thus affecting the formation of the lubricating oil additive.

[0047] When the reaction kettle generates the lubricating oil additive, the lubricating oil additive enters the reaction kettle under the action of the control system. The motor 11 rotates forward, and the ratchet 42 rotates forward. At this time, the stirrer 2 rotates forward. The stirrer 2 stirs and mixes the lubricating oil additive. At the same time, the forward-moving ratchet 42 drives the pawl 41 to deflect inward. The stirring blade 44 fixedly connected to the bottom of the ratchet 42 rotates forward. At this time, the stirring blade 44 drives the lubricating oil additive toward the bottom center, bringing the lubricating oil additive at the top from the upper end to the lower end. At the same time, the vertical baffle 5 swings inward. When squeezing forward, it is the flat surface of the ratchet 42 squeezing the pawl 41, thereby driving the spiral convex block 45 and the vertical baffle 5 to rotate forward. At this time, the lubricating oil additive will gather toward the center along the arc surface of the vertical baffle 5. At the same time, cooperating with the forward-rotating stirring blade 44, it further improves the gathering of the lubricating oil additive toward the middle and lower part, changing the flow direction of the lubricating oil additive;

[0048] When the motor 11 rotates in the reverse direction, while the stirrer 2 rotates, the ratchet 42 rotates in the reverse direction. Different from the forward rotation, due to the different rotation directions of the ratchet 42, the surface of the ratchet 42 that squeezes the pawl 41 is different. When squeezing in the reverse direction, it is the arc surface of the ratchet 42 squeezing the pawl 41, thereby driving the spiral convex block 45 and the vertical baffle 5 to rotate in the reverse direction. At this time, the lubricating oil additive will diffuse outward along the arc surface of the vertical baffle 5, and at the same time, the stirring blade 44 rotates in the reverse direction;

[0049] When the agitator 2 rotates in one direction, the stirring blades 44 push the lubricating oil additive in the opposite direction, forming a convection effect with the lubricating oil additive above, so that the lubricating oil additive is evenly mixed in the reaction kettle. The combination of the inclined stirring blades 44 and the paddle agitator 2 achieves a shearing effect in multiple directions. When the paddle agitator 2 and the inclined stirring blades 44 rotate, a shearing force is generated, enabling the reactants to be evenly mixed during the reaction. At the same time, the reversely rotating paddle agitator 2 forms a convection effect, causing the reactants to move upward from the bottom during stirring. The vertical baffle 5 at the top blocks the upward movement of the lubricating oil additive at the top, and the generated convection effect brings the reactants into the stirring area from different positions, allowing the lubricating oil additive to flow to different positions.

[0050] The vertical baffle 5 plays a guiding role in the eddy current formed by the agitator 2. During the reverse movement of the vertical baffle 5, the fixed rod 35 is driven to move, and the fixed rod 35 controls the transverse baffle 36 to extend. The transverse baffle 36 forms a diversion area, and the spiral convex block 45 fixedly installed at the bottom of the pawl 41 further stirs the dead zone area of the diversion area formed by the transverse baffle 36.
