TECHNICAL FIELD

[0001] The present application relates to the technical field of lubricating oil, in particular to a process and equipment for improving the viscosity of lubricating oil raw materials. BACKGROUND

[0002] The viscosity of base oil directly affects the performance of finished lubricating oil. By mixing high-viscosity base oil with ordinary base oil in a certain proportion, the viscosity of the final product can be flexibly adjusted. Adding an ethylene-propylene tackifier or a chlorobutyl tackifier to the base oil can not only improve the viscosity index but also improve the low-temperature fluidity. The key to improving the viscosity of lubricating oil base oil lies in the synergistic effect of base oil quality and additives, supplemented by chemical modification and process optimization. There are some studies on improving the viscosity of base oil in the prior art.

DETAILED DESCRIPTION

[0036] In order to make those skilled in the art better understand the technical solutions of the present application, the following will further introduce the present application in combination with the drawings.

[0037] Embodiment 1

[0038] The embodiment provides a process for improving the viscosity of a lubricating oil raw material, comprising the following steps:

[0039] Step one: heating the lubricating oil raw material (base oil) and quantitatively feeding the lubricating oil raw material into a stirring tank;

[0040] Step two: quantitatively feeding a thickening agent into the stirring tank, wherein the thickening agent comprises ethyl cellulose, silica gel, lithium soap, calcium soap or aluminum soap;

[0041] Step three: stirring and dispersing the lubricating oil raw material and the thickening agent in the stirring tank;

[0042] Step four: separating the stirred finished oil from the stirring tank and cleaning the stirring tank.

[0043] The process is completed in cooperation with a device for improving the viscosity of a lubricating oil raw material, as shown in Figure 1 and Figure 3 The device comprises a horizontal processing table 1, vertical end plates are formed at both ends of the processing table 1, two stirring tanks 2 capable of translating relative to the processing table 1 are installed on the processing table 1, a plurality of roller frames 7 are installed on the bottom surface of the stirring tank 2, rollers 8 are installed on the roller frames 7, and guide rails matched with the rollers 8 are formed on the upper surface of the processing table 1; a rigid frame 9 is installed between the two stirring tanks 2, and a push-pull handle 10 is installed on the stirring tank 2. Each stirring tank 2 has a corresponding stirring station and a discharging station; when the stirring tank 2 is at the stirring station, the raw material in the stirring tank 2 is dispersed; when the stirring tank 2 is at the discharging station, the raw material in the stirring tank 2 is discharged.

[0044] As shown in Figure 1 and Figure 3 A vertical stirring shaft 3 is rotatably installed in each stirring tank 2, stirring arms are arranged on the stirring shaft 3, a driven gear 4 located below the stirring tank 2 is fixedly installed at the bottom end of the stirring shaft 3, and a driving gear 5 for driving the driven gear 4 is installed on the processing table 1. When the stirring tank 2 is at the stirring station, the driven gear 4 thereon is in meshing state with the driving gear 5; when the stirring tank 2 is at the discharging station, the driven gear 4 thereon is in separation state with the driving gear 5. A motor is installed at the bottom of the processing table 1, and the motor drives the driving gear 5 to continuously rotate.

[0045] Specifically, the operator applies a pushing force or a pulling force to the push-pull handle 10 to drive the two stirring pots 2 and the rigid frame 9 to synchronously translate, so as to switch the positions of the stirring pots 2, when one of the stirring pots 2 is located at the stirring position, the other stirring pot 2 is located at the discharging position; in this way, the interval between two adjacent pots for processing is greatly shortened, and the processing efficiency is improved. It should be noted that the motor in the embodiment is always in a stable running state, compared with separately installing a motor on each stirring pot 2, on the one hand, the movement of the motor is avoided, on the other hand, the motor does not need to be frequently started and stopped, so that the wear of the motor is greatly reduced. In addition, a fixed rack can be installed on the processing table 1 corresponding to the position of the driven gear 4, so that the driven gear 4 also generates a certain rotating speed when the stirring pot 2 moves, which facilitates the driven gear 4 and the rotating driving gear 5 to enter the meshing state.

[0046] As shown in Figure 2 , the processing table 1 is provided with a feeding assembly 6 for feeding the stirring pot 2 through a support, the feeding assembly 6 is located at a position between the two stirring positions of the two stirring pots 2; the feeding assembly 6 comprises a horizontal rotating arm 601, one end of the rotating arm 601 is fixedly connected with a mounting disc 602, two feeding pipes 603 are fixedly installed on the mounting disc 602, the top of the feeding pipes 603 is externally connected with a storage box through a hose, the two feeding pipes 603 respectively supply base oil and thickening agent into the stirring pot 2. When the stirring pot 2 is located at the stirring position, the mounting disc 602 is coaxial with the stirring pot 2 and the stirring shaft 3 of the stirring pot 2, so as to ensure that the falling base oil and thickening agent are located in the middle region of the stirring pot 2, and facilitate uniform dispersion; when the stirring pot 2 translates relative to the processing table 1, the rotating arm 601 also rotates, specifically, the rotating arm 601 rotates 180° during the whole stroke of the stirring pot 2, that is, the mounting disc 602 rotates to a state coaxial with the other stirring pot 2 and the stirring shaft 3 of the stirring pot 2. The rotating arm 601 is fixedly provided with a sector gear 604 coaxial with the rotating axis of the rotating arm 601, and the rigid frame 9 is horizontally fixedly provided with a straight rack 14 matched with the sector gear 604. When the stirring pot 2 and the rigid frame 9 translate relative to the processing table 1, the straight rack 14 synchronously translates, the straight rack 14 meshes with the sector gear 604 during the translation process, and drives the sector gear 604, the rotating arm 601, the mounting disc 602 and the feeding pipe 603 to rotate.

[0047] As shown in Figure 1 and Figure 4As shown, a horizontal rod 11 is fixedly installed on the end plate of the processing table 1 at the position corresponding to the push-pull handle 10; a pin 12 is movably installed on the horizontal rod 11, and a slot 1001 that mates with the pin 12 is provided on the push-pull handle 10. The push-pull handle 10 is U-shaped and horizontally arranged, the middle section of the push-pull handle 10 has a circular cross-section, the slot 1001 is opened at the bottom of the middle section of the push-pull handle 10 and the slot 1001 is in a vertical state; the pin 12 is a vertical cylindrical shape and the top surface of the pin 12 is a hemispherical surface, the pin 12 and the horizontal rod 11 slide in the vertical direction and are connected by an elastic element.

[0048] Specifically, as the mixing tank 2 moves horizontally from the mixing station to the feeding station, the middle section of the push-pull handle 10 will contact the top surface of the pin 12. Figure 6 As shown, the push-pull handle 10 moves to the left and pushes the pin 12 downward until the pin 12 corresponds to the position of the slot 1001. Under the action of the elastic element, the pin 12 is inserted upward into the slot 1001, which limits the push-pull handle 10 and the mixing tank 2. This ensures that the mixing tank 2 is stably in the feeding position and that the driving gear 5 can be engaged with the driven gear 4 on the other mixing tank 2. When the feeding of the mixing tank 2 is completed and the mixing of the other mixing tank 2 is completed, the operator separates the pin 12 from the slot 1001, releases the pin 12 from the push-pull handle 10, and the operator can switch the position of the mixing tank 2 by pushing the push-pull handle 10.

[0049] like Figure 3 As shown, the mixing tank 2 and the roller frame 7 slide in a vertical direction and are connected by a helical spring. When the base oil and thickener in the mixing tank 2 gradually increase, its overall weight will increase, which will compress the helical spring. The mixing tank 2 will descend relative to the roller frame 7 and the processing table 1. The mixing tank 2 and the rigid frame 9 slide in a vertical direction. The rigid frame 9 is equipped with a support leg 13, and the bottom of the support leg 13 is equipped with a support wheel. When the mixing tank 2 descends relative to the roller frame 7 and the processing table 1, it also descends relative to the rigid frame 9 and the support leg 13.

[0050] Specifically, after the feeding assembly 6 delivers the predetermined amount of base oil and thickener into the mixing tank 2, the mixing tank 2 and the push-pull handle 10 are at the lowest point of their vertical stroke, that is, the push-pull handle 10 is at... Figure 6 The height shown indicates that it will disengage from the latch 12 during translation; after the mixing tank 2 has discharged all the finished oil inside at the unloading station, the mixing tank 2 will rise under the action of the spiral spring, and the push-pull handle 10 will also rise synchronously, and the push-pull handle 10 will move from... Figure 5The position is shown to rise and automatically separate from the latch 12; in this embodiment, the automatic lifting of the stirring tank 2 is realized by the change of the overall weight of the stirring tank 2 and the finished oil, so as to realize the automatic locking and unlocking of the stirring tank 2 by the latch 12, without the need for the operator to control the latch 12, thereby improving the convenience of operation.

[0051] Embodiment 2

[0052] As shown in Figure 7 and Figure 8 , the stirring tank 2 is provided with a lower oil hole 201 at the bottom, the lower oil hole 201 is a square hole, and a vertical elastic telescopic pipe 15 is fixedly installed on the processing table 1 corresponding to the position of the lower oil hole 201 of each stirring tank 2, the elastic telescopic pipe 15 is a square tube and is in a compressed state, and the bottom end of the elastic telescopic pipe 15 is circumscribed by a finished oil collecting box; a switch plate 16 for closing the lower oil hole 201 is slidingly installed on the side wall of the stirring tank 2 in the horizontal direction, the switch plate 16 is provided with a through slot 1601 matched with the lower oil hole 201, the through slot 1601 is a square slot, and an elastic member is connected between the switch plate 16 and the stirring tank 2. When the stirring tank 2 is in the stirring position, the switch plate 16 closes the lower oil hole 201, and the liquid in the stirring tank 2 cannot flow out from the lower oil hole 201; after the feeding assembly 6 completes the delivery of raw materials into the stirring tank 2, the bottom surface of the stirring tank 2 is lowered to a state of being flush with the top surface of the elastic telescopic pipe 15; when the stirring tank 2 translates from the stirring position to the discharging position, the bottom surface of the stirring tank 2 will be in contact with the top surface of the elastic telescopic pipe 15, and finally the stirring tank 2 reaches the predetermined discharging position, and the elastic telescopic pipe 15 is aligned with the lower oil hole 201; during this process, the switch plate 16 translates under the action of external force and presses the elastic member, the through slot 1601 translates to a position aligned with the lower oil hole 201, the liquid in the stirring tank 2 can flow into the elastic telescopic pipe 15 from the lower oil hole 201, and finally flow into the finished oil collecting box; during the discharging process of the stirring tank 2, its height is constantly lifted, and the overall lifting height does not exceed 5 cm, during this process, the elastic telescopic pipe 15 is constantly elongated, and the top surface of the elastic telescopic pipe 15 is always in contact with the bottom surface of the stirring tank 2, so as to avoid leakage of liquid between the stirring tank 2 and the elastic telescopic pipe 15.

[0053] As shown in Figure 7 and Figure 8As shown, the lifting section 1501 of the elastic telescopic pipe 15 is provided with a positioning hole 1502, and the end plate of the processing table 1 is slidably provided with a plug rod 17 penetrating through the fixed section of the elastic telescopic pipe 15 and matched with the positioning hole 1502 in the horizontal direction; the end plate is also slidably provided with an L-shaped plate 18 fixedly connected with the plug rod 17 in the horizontal direction, the horizontal section of the L-shaped plate 18 corresponds to the position of the switch plate 16, and the elastic element is connected between the L-shaped plate 18 and the end plate; the six rollers 8 on the bottom of the stirring tank 2 are evenly arranged around the stirring tank 2 in the circumferential direction; the corresponding two rollers 8 are fixedly connected with a horizontal round rod 19, the round rod 19 is connected with a pull wire 20, the outer wall of the lifting section 1501 is fixedly provided with a pull ring 21, and one end of the pull wire 20 penetrates through the fixed section of the elastic telescopic pipe 15 and is fixedly connected with the pull ring 21.

[0054] Specifically, in the initial state, the elastic telescopic pipe 15 is in the Figure 8 shortest state, in which the top surface of the lifting section 1501 is flush with the bottom surface of the stirring tank 2, the plug rod 17 is inserted into the positioning hole 1502, and the lifting section 1501 has a rising trend; as the stirring tank 2 translates to the left side of the discharging station, the left end of the switch plate 16 first abuts against the right end of the horizontal section of the L-shaped plate 18, and the two generate a mutual force; the bottom surface of the stirring tank 2 also abuts against the top surface of the lifting section 1501; as the stirring tank 2 continues to move to the left, the switch plate 16 pushes the L-shaped plate 18 and the plug rod 17 to move to the left synchronously, and at the same time, the switch plate 16 moves to the right relative to the stirring tank 2; when the stirring tank 2 reaches the discharging station, the plug rod 17 is separated from the positioning hole 1502, and the through slot 1601 on the switch plate 16 also translates to a position aligned with the oil outlet hole 201; in this state, the top surface of the lifting section 1501 is closely attached to the bottom surface of the stirring tank 2, and when the stirring tank 2 rises, the lifting section 1501 also rises synchronously to ensure that the elastic telescopic pipe 15 is always attached to the bottom surface of the stirring tank 2; after the discharging is completed, the stirring tank 2 translates to the right, the L-shaped plate 18 makes the right end of the plug rod 17 closely attached to the side wall of the lifting section 1501 under the action of the elastic element, and when the stirring tank 2 moves to the right to pull the pull wire 20 tightly and continues to move to the right, the pull wire 20 will make the lifting section 1501 descend by pulling the pull ring 21; when the stirring tank 2 moves to the right to the stirring station, the lifting section 1501 descends to a position where the plug rod 17 is aligned with the positioning hole 1502, and the plug rod 17 automatically inserts into the positioning hole 1502 to keep the total length of the elastic telescopic pipe 15 at Figure 8 the state shown. As described above, in the embodiment, the stirring tank 2 automatically discharges after reaching the discharging station, the elastic telescopic pipe 15 continuously extends and is always attached to the bottom surface of the stirring tank 2 during the discharging process, thereby avoiding the leakage of finished oil; after the stirring tank 2 completes the discharging and returns to the stirring station, the elastic telescopic pipe 15 automatically restores to the initial state, thereby preparing for the next work.

[0055] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application.
