Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a lubricating oil additive reactor. Background Art

[0002] Lubricant additive reactor is a device used to react, convert or mix raw materials and produce lubricant additives. Lubricant additives refer to chemicals added to base lubricants to improve the performance and function of lubricants.

[0003] In the chemical product production workshop, when the lubricant additive is reacted in the reactor, since the lubricant additive is a high-viscosity lubricant additive, the lubricant additive is easily accumulated in the dead zone of the baffle during the reaction, making it unable to flow, resulting in uneven mixing of the lubricant additive during the reaction. At the same time, the dead zone is not conducive to cleaning.

[0004] In order to ensure that the lubricant additive is fully stirred, some rods or plates are set on the inner wall of the reactor, so that the lubricant additive can flow in a certain direction under the action of the stirring rod. However, the stirring dead zone caused by the stirring rod or plate hinders the flow and mixing of the lubricant additive, causing the reactants to accumulate in the stirring dead zone. At this time, some lubricant additives will not flow even when stirred. The lubricant additive is unevenly mixed during the reaction, which can easily lead to product instability and change its performance during use, thereby affecting the performance and quality of the lubricant additive. At the same time, the stirring dead zone will cause uneven temperature distribution during the reaction, resulting in a temperature gradient, resulting in a lower reaction rate in the dead zone and a higher reaction rate in other areas, which will lead to inconsistent reaction intensity, thereby affecting the yield and efficiency of the reaction.

[0005] In the prior art, one end of the vertical baffle is fixedly connected to the pipe mouth of the upper head of the reactor through a flange, and the other end is inserted into the lubricating oil additive inside the equipment. During the generation of the lubricating oil additive in the reactor, the viscosity of the lubricating oil additive in the reactor increases as the reaction proceeds. However, when the liquid in the reactor flows to the vertical baffle, a laminar flow effect is generated, thereby restricting the lateral movement of the fluid. The lubricating oil additive in the reactor is prone to uneven mixing during the reaction.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs a lubricating oil additive reactor to solve the above technical problems. Summary of the invention

[0007] The object of the present invention is to provide a lubricating oil additive reactor. In order to solve the problem that when the liquid in the reactor flows to the vertical baffle, a laminar flow effect will be generated, thereby restricting the lateral movement of the fluid, and the lubricating oil additive in the reactor is prone to uneven mixing during the reaction process, the shear force distribution in the reactor is changed and the turbulent effect of the fluid is improved by reciprocating swinging, so that the lubricating oil additive can be evenly mixed in the reactor.

[0008] A lubricating oil additive reactor, comprising a reactor body, an agitator, an opening and closing assembly, a swing assembly and a vertical baffle, wherein the agitator is installed inside the reactor body, the vertical baffle is connected to the reactor body, the swing assembly is installed at the lower side of the vertical baffle, the swing assembly and the vertical baffle move at the same frequency to achieve uniform distribution of the lubricating oil additive, the opening and closing assembly is installed at the lower side of the swing assembly, and the opening and closing assembly separates the flow area of ​​the lubricating oil additive through the swing of the vertical baffle; When the motor rotates forward, the vertical baffle is placed in the reactor and swings forward. When the viscosity in the reactor reaches a predetermined value, the motor in the reactor rotates in the opposite direction. The motor drives the ratchet to rotate while the motor rotates. The ratchet drives the pawl to rotate while the ratchet rotates. When the vertical baffle is swinging, the vertical baffle guides the vortex formed by the agitator to prevent the movement path of the vortex from being disordered. At the same time, the lubricating oil additive in the reactor is evenly mixed. The vertical baffle is connected to the inner wall of the kettle body through a spring. When the vertical baffle swings, the spring restores the vertical baffle to its original position. At the same time, the spring prevents the vertical baffle from hitting the inner wall of the reactor during the swinging of the vertical baffle, causing the liquid inside the reactor to change its path, resulting in a change in the temperature distribution in the reactor. A bracket is installed at the bottom of the kettle body, and a shock-absorbing spring is installed on the inner wall of the bracket. The shock-absorbing spring reduces the vibration caused by the reactor when the agitator rotates. At the same time, a fixing bracket is installed on the side wall of the kettle body, so that when the reactor is installed, the reactor is installed on the wall, which makes the installation of the reactor convenient. A swing component is installed on the lower side of the vertical baffle. The swing component and the vertical baffle move at the same frequency to achieve uniform distribution of the lubricating oil additive. The swing component moves under the action of the agitator, and the stirring blades in the swing component swing. When the viscosity of the lubricating oil additive in the reactor increases, the stirring blades in the swing component rotate simultaneously with the agitator, so that the lubricating oil additive is uniformly distributed. The lubricating oil additive is evenly mixed when the oil additive rotates. An opening and closing assembly is installed on the lower side of the swinging assembly. The opening and closing assembly separates the flow area of ​​the lubricating oil additive by the swinging 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 flow partitions during the reaction. At the same time, when the transverse baffle is extended, the transverse baffle prevents the direct rotation of the liquid, so that the transverse baffle forms convection and disturbance in different areas, thereby increasing the mixing and contact between the liquids in the reactor during the reaction.

[0009] The swing assembly includes a pawl, a ratchet, a fixed block, a stirring blade and a spiral protrusion. The bottom of the vertical baffle is equipped with a pawl, the ratchet is installed below the agitator, the fixed block is installed at the bottom of the ratchet, the stirring blade is arranged obliquely and installed on the side wall of the fixed block, and the spiral protrusion is installed below the pawl. The spiral protrusion guides the flow of lubricating oil additives to eliminate the dead zone area of ​​the diversion zone formed during the expansion and contraction of the horizontal baffle. The spiral protrusion guides the contact between the lubricating oil additives and the bottom end of the spiral protrusion during the swinging process. The spiral protrusion prevents the logistics from being retained in the diversion zone during the flow. At the same time, the spiral protrusion changes the flow path and speed of the lubricating oil additives in the diversion zone during the movement, so that the spiral protrusion introduces turbulence during the movement, thereby promoting the mixing and reaction of the lubricating oil additives. The agitator is rotatably connected to the ratchet, the bottom of the ratchet is fixedly installed with a fixed block, and stirring blades are fixedly installed on both sides of the fixed block. When the motor rotates forward, the ratchet rotates forward, and the agitator rotates forward synchronously at this time. The agitator 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 ratchet moving forward will drive the ratchet pawl to deviate 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 to the bottom center, and bring the lubricating oil additive on the top from the upper end to the lower end. At the same time, the vertical baffle will swing inward, thereby changing the flow direction of the lubricating oil additive when disturbance occurs, so that the lubricating oil additive can fill the inside of the kettle body when rotating forward; during forward extrusion, the ratchet is squeezed by the plane of the ratchet, thereby driving the spiral protrusion and the vertical baffle to rotate forward. At this time, the lubricating oil additive will gather to the center along the arc surface of the vertical baffle, and at the same time, cooperate with the stirring blade rotating forward to further increase the lubricating oil additive to gather toward the middle and lower part, thereby changing the flow direction of the lubricating oil additive; When the motor rotates in the reverse direction, the stirrer rotates and the ratchet rotates in the reverse direction. Unlike the forward rotation, the different rotation directions of the ratchet will drive the ratchet to squeeze the different surfaces of the ratchet pawl. In the reverse extrusion, the arc surface of the ratchet squeezes the ratchet pawl, which in turn drives the spiral protrusion and the vertical baffle to rotate in the reverse direction. At this time, the lubricating oil additive will diffuse outward along the arc surface of the vertical baffle. At the same time, the counter-rotating stirring blades will further make the lubricating oil additive move outward centrifugally, changing the flow direction of the lubricating oil additive. The stirring blade fixedly connected to the bottom of the ratchet wheel rotates. When the stirring blade rotates, the stirrer forms a convection effect with the stirring blade on the top when stirring, so that the lubricating oil additive is evenly mixed in the reactor. The stirring blade is tilted on the fixed block. The combination of the tilted stirring blade and the paddle stirrer realizes shear effects in multiple directions. The paddle stirrer and the tilted stirring blade will generate shear force when rotating. The shear force will shear the lumps formed by the reactants in the reactor and break up the lumps formed in the reactor. At the same time, the shear force shears the lubricating oil additive in the reaction, so that the reactants are evenly mixed during the reaction. At the same time, the paddle stirrer forms a convection effect, and moves the reactants from the bottom to the top when stirring. The top tilted stirring blade moves the top lubricating oil additive from the top to the bottom. The convection effect generated at the same time 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 generated by the convection effect mixes the lubricating oil additive evenly.

[0010] The cam is provided with a plurality of connecting rods, and the connecting rods are arranged on the upper side of the plurality of connecting rods, and the connecting rods are arranged on the upper side of the plurality of connecting rods. Then, the end of the transverse baffle away from the agitator is set to be pointed. The transverse baffle changes the flow speed of the fluid through the pointed shape to achieve uniform stirring of the lubricating oil additive by the agitator. The pointed baffle enhances the shear and disturbance of the fluid in the reactor, and improves the suspended particles in the reactants, so that the fluid speed in the reactor changes, interacts with the stirring of the agitator, and makes the agitator stir the lubricating oil additive uniformly. The transverse baffle changes the shear layer inside the reactor body through the swing of the vertical baffle to achieve uniform distribution of shear force inside the reactor body. The vertical baffle changes the shear layer inside the reactor body while swinging. At the same time, the transverse baffle reciprocates horizontally under the action of the fixed rod. The transverse baffle changes the shear layer of the fluid at the bottom. At the same time, the transverse baffle increases the disturbance at the bottom when it 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 the top disturbance in the reactor make the shear force of the fluid in the reactor evenly dispersed, thereby achieving uniform mixing of the lubricating oil additive.

[0011] A serrated groove is provided on the shaft of the agitator, and the agitator adjusts the fluid flow intensity around the transverse baffle through the serrated groove, thereby achieving stirring of the lubricant additive. When the motor rotates in the reverse direction, the motor drives the agitator to stir. When the lubricant additive is put into the reactor, the serrated groove provided on the agitator will bring the lubricant additive in, causing the fluid in the reactor to be disturbed, thereby changing the flow direction of the lubricant additive under the condition of disturbance. The shear force generated by the transverse baffle on the fluid in the telescopic state is evenly distributed, so that the lubricant additive is evenly mixed in the reactor. When the motor rotates forward, the agitator rotates, and the groove provided on the agitator changes the flow characteristics around the agitator. The serrated groove breaks the laminar flow state when rotating, so that the agitator forms a turbulent effect when stirring, thereby achieving even mixing of the lubricant additive in the reactor.

[0012] 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 vortex formed by the agitator through the curve. The agitator will form a vortex when stirring and mixing the lubricating oil additive. The vertical baffle guides the flow of the vortex through the curve to avoid confusion and disorder of the vortex. When the viscosity of the lubricating oil additive in the reactor increases to a predetermined value, the motor starts to rotate and drives the ratchet to rotate. The ratchet and the pawl cooperate to move, and the vertical baffle fixedly installed on the upper side of the pawl starts Swinging. During the swinging process of the vertical baffle, the curved shape of the baffle will form eddies. When the viscous lubricating oil additive passes through the curved part of the vertical baffle, the eddies generated by the curved part of the vertical baffle will drive the viscous lubricating oil additive to move, thereby avoiding uneven mixing of the lubricating oil additive during the reaction process. At the same time, the vertical baffle will change the distribution of the flow field and the shear force in the reactor during the swinging process, thereby generating turbulence, so that the lubricating oil additive in the reactor is evenly mixed under the joint action of the agitator and the vertical baffle.

[0013] 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 length between the two ends to achieve uniform mixing of the lubricant additive. The narrow end of the vertical baffle limits the flow range of the fluid, increasing the shear force when the lubricant additive is mixed. At the same time, the wide end of the vertical baffle provides a flow space to diffuse the fluid from the turbulent area on the narrow side to the laminar area on the wide side, so that the lubricant additive is evenly mixed. At the same time, the rotation of the ratchet drives the vertical baffle to swing. In the process of adding the lubricant additive to the reactor to form the lubricant additive, the viscosity of the fluid in the reactor increases. In addition, the vertical baffle provides additional stirring force and shear force for the mixing of the lubricant additive during the swinging process, thereby increasing the reaction rate of the lubricant additive. At the same time, when the viscosity of the lubricant additive in the reactor increases to a predetermined value, the motor starts to rotate to drive the ratchet to rotate, and the ratchet and the pawl move in coordination, and the vertical baffle fixed on the upper side of the pawl starts to swing. In the process of the vertical baffle swinging, the vertical baffle will form an asymmetric flow field. The vertical baffle will provide different shear rates for the lubricant additive during the flow of the lubricant additive, thereby promoting the mixing and stirring of the lubricant additive.

[0014] The root length of the stirring blade is greater than the tip length. The stirring blade forms a shear effect through the difference between the root length and the tip length to disperse the clumps formed by the lubricant additive. When the ratchet rotates, the stirring blade is driven to rotate. The asymmetric shape of the stirring blade forms a shear effect between the root and the tip of the stirring blade. The shear effect forms clumps of lubricant additives when the lubricant additives are placed in the reactor. Under the action of the shear effect, the clumps are destroyed, so that the lubricant additives are mixed evenly and dispersed under the joint action of the stirring blade and the agitator. At the same time, the length of the blade root is greater than the length of the blade tip to enhance the intensity of turbulence. The turbulence formed when the stirring blade is stirring makes the lubricant additives mix evenly. At the same time, through holes are opened on the stirring blade, and the through holes are radially distributed along the root of the stirring blade in the opposite direction to the tip of the blade, so as to promote mutual contact and mixing between the lubricant additives and make the lubricant additives react evenly.

[0015] A vertical baffle is fixedly installed on the upper side of the ratchet, a circulation hole is provided on the top of the vertical baffle, and a fixing hole is provided on the ratchet. When the vertical baffle swings, the circulation hole provided on the vertical baffle and the fixing hole provided on the ratchet are on the same axis. The vertical baffle realizes uniform transmission of stirring force through the circulation hole and the fixing hole being on the same axis. When the motor rotates in the opposite direction, the circulation hole provided on the vertical baffle and the fixing hole provided on the ratchet are on the same axis. The vertical baffle transmits the stirring force to the fixing hole provided on the ratchet through the circulation hole, and transmits the stirring force to the lubricating oil additive during the movement of the vertical baffle, thereby realizing uniform mixing of the lubricating oil additive. At the same time, the viscosity of the lubricating oil additive increases during the reaction, and the stirring force evenly transfers the heat in the lubricating oil additive, thereby preventing uneven temperature distribution of the lubricating oil additive in the reactor, thereby affecting the formation of the lubricating oil additive.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention provides a lubricating oil additive reactor. When the motor rotates forward, the ratchet rotates forward, and the agitator rotates forward synchronously. The agitator 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 ratchet moving forward will drive the pawl to deviate 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 and bring the lubricating oil additive on the top from the upper end to the lower end. At the same time, the vertical baffle will swing inward, thereby changing the flow direction of the lubricating oil additive when a disturbance is generated, so that the lubricating oil additive can fill the interior of the reactor during forward rotation.

[0017] 2. The present invention provides a lubricating oil additive reactor. During forward extrusion, the flat surface of the ratchet wheel extrude the pawl, thereby driving the spiral protrusion 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, and at the same time, cooperate with the forward rotating stirring blade to further increase the aggregation of the lubricating oil additive toward the middle and lower part, thereby changing the flow direction of the lubricating oil additive; during reverse extrusion, the arc surface of the ratchet wheel extrude the pawl, thereby driving the spiral protrusion and the vertical baffle to rotate in the opposite direction. At this time, the lubricating oil additive will diffuse outward along the arc surface of the vertical baffle. At the same time, cooperate with the reverse rotating stirring blade to further make the lubricating oil additive move centrifugally outward, thereby changing the flow direction of the lubricating oil additive.

DETAILED DESCRIPTION

[0021] like Figures 1 to 5 As shown, a lubricating oil additive reactor comprises a reactor body 1, an agitator 2, a vertical baffle 5, a swing assembly 4 and an opening and closing assembly 3. The agitator 2 is installed inside the reactor body 1, and the vertical baffle 5 is installed near the agitator 2. When the motor 11 rotates forward, the vertical baffle 5 is placed in the reactor and swings forward. When the viscosity in the reactor reaches a predetermined value, the motor 11 in the reactor rotates reversely. When the motor 11 rotates, it drives the ratchet 42 to rotate. When the ratchet 42 rotates, it drives the ratchet 41 to rotate. When the vertical baffle 5 swings, the vertical baffle 5 forms a swinging motion on the agitator 2. The eddy current plays a guiding role to prevent the eddy current from being disordered in its movement path. At the same time, the lubricating oil additive in the reactor is 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 liquid inside the reactor to change its path, thereby changing the temperature distribution in the reactor. A bracket 12 is installed at the bottom of the reactor body 1, and a shock-absorbing spring is installed on the inner wall of the bracket 12. The shock-absorbing spring reduces the vibration of the reactor when the agitator 2 rotates. The vibration caused by the reactor, and the side wall of the reactor body 1 is installed with a fixing frame, so that when the reactor is installed, the reactor is installed on the wall, which makes the installation of the reactor convenient. The lower side of the vertical baffle 5 is installed with a swing component 4, and the swing component 4 and the vertical baffle 5 move at the same frequency to achieve uniform distribution of the lubricating oil additive. The swing component 4 moves under the action of the agitator 2, and the stirring blade 44 in the swing component 4 swings. When the viscosity of the lubricating oil additive in the reactor increases, the stirring blade 44 in the swing component 4 rotates simultaneously with the agitator 2, so that the lubricating oil additive is evenly mixed when the lubricating oil additive is rotated. The lower side of the swing component 4 is equipped with an opening and closing component 3. The opening and closing component 3 separates the flow area of ​​the lubricating oil additive by the swinging 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 component 3 to extend. The transverse baffle 36 separates the lubricating oil additive in the reactor, so that the lubricating oil additive forms a flow partition during the reaction process. At the same time, when the transverse baffle 36 is extended, the transverse baffle 36 prevents the direct rotation of the liquid, so that the transverse baffle 36 forms convection and disturbance in different areas, thereby increasing the mixing and contact between the liquids in the reactor during the reaction.

[0022] like 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 protrusion 45. The pawl 41 is fixedly installed at the middle position of the bottom of the vertical baffle 5, and the spiral protrusion 45 is installed at the bottom of the pawl 41. The transverse baffle 36 and the spiral protrusion 45 are installed at the bottom of the spiral protrusion 45. The spiral protrusion 45 guides the flow of the lubricating oil additive to eliminate the dead zone of the diversion zone formed during the expansion and contraction of the transverse baffle 36. The spiral protrusion guides the contact between the lubricating oil additive and the bottom end of the spiral protrusion 45 during the swinging process. The spiral protrusion prevents the logistics from being retained in the diversion zone when flowing. At the same time, the spiral protrusion changes the flow path and speed of the lubricating oil additive in the diversion zone during the movement, so that the spiral protrusion introduces turbulence during the movement, thereby promoting the mixing and reaction of the lubricating oil additive. The agitator 2 is rotatably connected to the ratchet 42. The fixed block 43 is fixedly installed at the bottom of the ratchet 42, and the stirring blades 44 are fixedly installed on both sides of the fixed block 43. When the motor 11 rotates forward, the ratchet 42 rotates forward, and the agitator 2 rotates forward synchronously at this time. The agitator 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 ratchet 42 moving forward will drive the pawl 41 to deviate inward, and 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 to the bottom center, and bring the lubricating oil additive on 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 when a disturbance occurs, so that the lubricating oil additive can fill the inside of the kettle body 1 during forward rotation; during forward extrusion, the plane of the ratchet 42 squeezes the pawl 41, thereby driving the spiral protrusion 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, and at the same time, cooperate with the stirring blade 44 rotating forward to further increase the lubricating oil additive to gather toward the middle and lower part, thereby changing the flow direction of the lubricating oil additive; When the motor 11 rotates in the reverse direction, the stirrer 2 rotates and the ratchet 42 rotates in the reverse direction. Unlike the forward rotation, the different rotation directions of the ratchet 42 will drive the ratchet 42 to squeeze the different surfaces of the ratchet 41. In the reverse extrusion, the arc surface of the ratchet 42 squeezes the ratchet 41, thereby driving the spiral protrusion 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 counter-rotating stirring blade 44 will further make the lubricating oil additive perform centrifugal motion outward, thereby changing the flow direction of the lubricating oil additive. The stirring blade 44 fixedly connected to the bottom of the ratchet 42 rotates. When the stirring blade 44 rotates, the stirrer 2 forms a convection effect with the stirring blade 44 at the top during stirring, so that the lubricating oil additive is evenly mixed in the reactor. The stirring blade 44 is tilted on the fixed block 43. The combination of the tilted stirring blade 44 and the paddle stirrer 2 realizes a shear effect in multiple directions. The paddle stirrer 2 and the tilted stirring blade 44 will generate a shear force when rotating. The shear force will shear the agglomerates formed by the reactants in the reactor, and the agglomerates formed in the reactor will be The lubricant additive in the reaction is broken up, and the shear force shears the lubricant additive in the reaction, so that the reactants are evenly mixed during the reaction. At the same time, the paddle agitator 2 forms a convection effect, and the reactants are moved from the bottom to the top during stirring. The stirring blades 44 arranged at an angle on the top move the lubricant additive on the top from the top to the bottom. At the same time, the convection effect generated brings the reactants into the stirring area from different positions, so that the lubricant additive is brought into the stirring area from different positions. When the lubricant additive is stirred, the convection effect of the lubricant additive mixes the lubricant additive evenly.

[0023] like Figure 6As shown, 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 reactor. The connecting rod 33 is fixedly installed on the upper side of the fixed disk 34. The connecting rod 33 is arranged in an annular manner on the fixed disk 34. The rotating disk 31 is rotatably installed on the upper side of the fixed disk 34. The moving groove 32 is opened on the rotating disk 31. The fixing rod 35 is installed on the rotating disk 31. When the motor 11 rotates in the reverse direction, the motor 11 drives the agitator 2 to rotate, and the agitator 2 applies lubricating oil to the agitator 2. The additive is stirred, and at the same time, the ratchet wheel 42 is driven to rotate. When the ratchet wheel 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 extending 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 extension and retraction of the transverse baffle 36, changing the flow direction of the fluid in the reactor. A moving rod 37 is installed at the bottom of the transverse baffle 36. The movable rod 37 is slidably connected to the movable groove 32. The end of the transverse baffle 36 away from the stirrer 2 is set to a pointed shape 361. The transverse baffle 36 changes the flow speed of the fluid through the pointed shape 361 to achieve uniform stirring of the lubricating oil additive by the stirrer 2. The transverse baffle 36 with the pointed shape 361 enhances the shear and disturbance of the fluid in the reactor and improves the suspended particles in the reactants, so that the fluid speed in the reactor changes and interacts with the stirring of the stirrer 2, so that the stirrer 2 stirs the lubricating oil additive uniformly. The transverse baffle 36 swings through the vertical baffle 5. The shear layer inside the kettle body 1 is changed to achieve uniform distribution of shear force inside the kettle body 1. The vertical baffle 5 changes the shear layer inside the kettle body 1 while swinging. At the same time, the transverse baffle 36 reciprocates transversely 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, the transverse baffle 36 increases the disturbance at the bottom when moving at the bottom. When the vertical baffle 5 moves at the top of the reactor, the disturbance at the top is increased. The bottom disturbance and the top disturbance in the reactor make the shear force of the fluid in the reactor evenly dispersed, thereby achieving uniform mixing of the lubricating oil additive.

[0024] The width of one end of the vertical baffle 5 is greater than that of the other end. The vertical baffle 5 introduces turbulent and laminar disturbances of the fluid through the difference in length between the two ends to achieve uniform mixing of the lubricant additive. The narrow end of the vertical baffle 5 limits the flow range of the fluid, increasing the shear force when the lubricant additive is mixed. At the same time, the wide end of the vertical baffle 5 provides a flow space to diffuse the fluid from the turbulent area on the narrow side to the laminar area on the wide side, so that the lubricant additive is evenly mixed. At the same time, under the rotation of the ratchet 42, the vertical baffle 5 is driven to swing. In the process of adding the lubricant additive to the reactor to form the lubricant additive, the viscosity of the fluid in the reactor increases, and the vertical baffle 5 is rotated. During the swinging process, the plate 5 provides additional stirring force and shear force for the mixing of the lubricant additive, thereby increasing the reaction rate of the lubricant additive. At the same time, when the viscosity of the lubricant additive in the reactor increases to a predetermined value, the motor 11 starts to rotate to drive the ratchet 42 to rotate, and the ratchet 42 and the pawl 41 move in coordination, and 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 will form an asymmetric flow field. During the flow of the lubricant additive, the vertical baffle 5 will provide different shear rates for the lubricant additive, thereby promoting the mixing and stirring of the lubricant additive.

[0025] A serrated groove 21 is provided on the shaft of the agitator 2. The agitator 2 adjusts the fluid flow intensity around the transverse baffle 36 through the serrated groove 21, thereby stirring the lubricating oil additive. When the motor 11 rotates in the reverse direction, the motor 11 drives the agitator 2 to stir. When the lubricating oil additive is put into the reactor, the serrated groove provided on the agitator 2 will bring the lubricating oil additive in, causing the fluid in the reactor to be disturbed, thereby changing the flow direction of the lubricating oil additive under the condition of disturbance. The shear force generated by the transverse baffle 36 on the fluid in the telescopic state is evenly distributed, so that the lubricating oil additive is evenly mixed in the reactor. When the motor 11 rotates forward, the agitator 2 rotates, and the groove provided on the agitator 2 changes the flow characteristics around the agitator 2. The serrated groove breaks the laminar state when rotating, so that the agitator 2 strengthens the turbulent effect when stirring, thereby achieving uniform mixing of the lubricating oil additive in the reactor.

[0026] The width of the left end of the vertical baffle 5 is greater than that of the right end. The vertical baffle 5 introduces turbulent and laminar disturbances of the fluid through the difference in length at both ends to achieve uniform mixing of the lubricant additive. The narrow end of the vertical baffle 5 limits the flow range of the fluid, increasing the shear force when the lubricant additive is mixed. At the same time, the wide end of the vertical baffle 5 provides a flow space to diffuse the fluid from the narrow side turbulent area to the wide side laminar area, so that the lubricant additive is evenly mixed. At the same time, under the rotation of the ratchet 42, the vertical baffle 5 is driven to swing. In the process of adding the lubricant additive to the reactor to form the lubricant additive, the lubricant additive in the reactor As the viscosity of the fluid increases, the vertical baffle 5 provides additional stirring force and shear force for the mixing of the lubricant additive during the swinging process, thereby increasing the reaction rate of the lubricant additive. At the same time, when the viscosity of the lubricant additive in the reactor increases to a predetermined value, the motor 11 starts to rotate to drive the ratchet 42 to rotate, and the ratchet 42 and the pawl 41 move in coordination, and 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 portion of the vertical baffle 5 restricts the flow of the viscous lubricant additive, and the wide side portion of the vertical baffle 5 limits the range of the vortex.

[0027] like Figure 8 As shown, the stirring blade 44 is in a spiral shape, and one side of the stirring blade 44 in the rotation direction is an inner concave surface.

[0028] When the stirring blade 44 rotates forward, it will drive the lubricating oil additive spiral downward and push the lubricating oil additive toward the center. When the stirring blade 44 rotates reversely, it will drive the lubricating oil additive spiral upward and move outward, thereby mixing with the lubricating oil additive above to improve uniformity.

[0029] 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 clumps formed by the lubricant additive. When the ratchet 42 rotates, the stirring blade 44 is driven to rotate. The asymmetric shape of the stirring blade 44 forms a shear effect between the blade root 441 and the blade tip 442 of the stirring blade 44. The shear effect forms clumps of lubricant additives when the lubricant additives are placed in the reactor. Under the action of the shear effect, the clumps are destroyed, so that the lubricant additives are mixed evenly and dispersed under the joint action of the stirring blade 44 and the stirrer 2. At the same time, the length of the blade root 441 is greater than the length of the blade tip 442 to enhance the intensity of turbulence. The turbulence formed when the stirring blade 44 is stirring makes the lubricant additives mix evenly. At the same time, a through hole is opened on the stirring blade 44, and the through holes are radially distributed along the blade root 441 of the stirring blade 44 in the opposite direction to the blade tip 442, so as to promote mutual contact and mixing between the lubricant additives, so that the lubricant additives react evenly.

[0030] A vertical baffle 5 is fixedly installed on the upper side of the ratchet 41, and a flow hole 51 is opened on the top of the vertical baffle 5, and a fixing hole 411 is opened on the ratchet 41. When the vertical baffle 5 swings, the flow hole 51 opened on the vertical baffle 5 and the fixing hole 411 opened on the ratchet 41 are on the same axis, and the vertical baffle 5 is located on the same axis to achieve uniform transmission of stirring force. When the motor 11 rotates in the opposite direction, the flow hole 51 opened on the vertical baffle 5 and the fixing hole 411 opened on the ratchet 41 are on the same axis, and the vertical baffle 5 transmits the stirring force to the fixing hole 411 opened on the ratchet 41 through the flow hole 51, and transmits the stirring force to the lubricating oil additive during the movement of the vertical baffle 5, thereby achieving uniform mixing of the lubricating oil additive. At the same time, the viscosity of the lubricating oil additive increases during the reaction, and the stirring force evenly transfers the heat in the lubricating oil additive to prevent uneven temperature distribution of the lubricating oil additive in the reactor, thereby affecting the formation of the lubricating oil additive.

[0031] When the reactor is reacting and generating lubricating oil additives, the lubricating oil additives enter the reactor under the action of the control system, the motor 11 rotates forward, the ratchet 42 rotates forward, and the stirrer 2 rotates forward at this time. The stirrer 2 stirs and mixes the lubricating oil additives, and at the same time, the ratchet 42 moving forward will drive the ratchet 41 to deviate inward, and 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 additives to the bottom center, and bring the lubricating oil additives on the top from the upper end to the lower end. At the same time, the vertical baffle 5 will swing inward. During positive extrusion, the plane of the ratchet 42 squeezes the ratchet 41, thereby driving the spiral protrusion 45 and the vertical baffle 5 to rotate forward. At this time, the lubricating oil additives will gather toward the center along the arc surface of the vertical baffle 5, and at the same time, cooperate with the stirring blade 44 rotating forward to further increase the lubricating oil additives to gather toward the middle and lower part, thereby changing the flow direction of the lubricating oil additives. When the motor 11 rotates in the reverse direction, the stirrer 2 rotates and the ratchet 42 rotates in the reverse direction. Unlike the forward rotation, the different rotation directions of the ratchet 42 will drive the ratchet 42 to squeeze the different surfaces of the ratchet 41. In the reverse extrusion, the arc surface of the ratchet 42 squeezes the ratchet 41, thereby driving the spiral protrusion 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 the stirring blade 44 will rotate in the reverse direction. When the agitator 2 rotates in the opposite 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 reactor. The combination of the inclined stirring blades 44 and the paddle agitator 2 realizes shear effects in multiple directions. The paddle agitator 2 and the inclined stirring blades 44 will generate shear force when rotating, so that the reactants are evenly mixed during the reaction. At the same time, the reverse rotating paddle agitator 2 forms a convection effect, which moves the reactants from the bottom to the top during stirring. The vertical baffle 5 on the top blocks the lubricating oil additive on the top from moving upward. The resulting convection effect brings the reactants into the stirring area from different positions, so that the lubricating oil additive flows to different positions.

[0032] The vertical baffle 5 guides the vortex formed by the agitator 2. The vertical baffle 5 drives the fixed rod 35 to move during the reverse movement. The fixed rod 35 controls the transverse baffle 36 to extend. The transverse baffle 36 forms a diversion area. The spiral protrusion 45 fixedly installed at the bottom of the ratchet 41 further stirs the dead zone of the diversion area formed by the transverse baffle 36.
