Description

Technical Field

[0002] Lubricating oil is a kind of oil used to reduce friction and wear between mechanical devices. It can reduce the friction coefficient and energy consumption.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0046] According to the following Figure 1-Figure 18 The lubricating oil heating and blending system provided by an embodiment of the present invention is described.

[0047] Embodiment 1: This embodiment refers to Figure 1-Figure 17 .

[0048] See also Figure 1 As shown, an embodiment of the present invention provides a lubricating oil heating and blending system, comprising a base tank 1, a blending tank 2, a filter 3 and a finished oil tank 4. The base oil in the base tank 1 enters the blending tank 2 to be mixed with additives, and the mixed oil enters the filter 3 for filtration, and can then be stored in the finished oil tank 4 for storage.

[0049] Specific, combined Figure 2-Figure 5 As shown, the blending tank 2 includes a tank body 225 as a blending place, and an outer main shaft 240 is provided at the internal axis of the tank body 225. The outer main shaft 240 can rotate, and second transverse stirring rods 253 are provided on both sides thereof. When the outer main shaft 240 rotates, it can drive the second transverse stirring rod 253 to rotate, and when the second transverse stirring rod 253 rotates, the base oil and the additive can be stirred and mixed. The second transverse stirring rod 253 is a cavity structure, and a plunger 280 is provided in the second transverse stirring rod 253, so that the second transverse stirring rod 253 actually also serves as a cylinder body of the plunger 280, and the plunger 280 can reciprocate in the cylinder body, and the moving direction of the plunger 280 is along the radial direction of the tank body 225.

[0050] like Figure 3-Figure 5As shown, a longitudinal stirring rod 251 and a one-way valve 260 are also provided. The longitudinal stirring rod 251 is arranged on the second transverse stirring rod 253 along the axial direction of the tank body 225, and the longitudinal stirring rod 251 is a tubular structure with openings at both ends. The one-way valve 260 is assembled between the longitudinal stirring rod 251 and the first transverse stirring rod 252, so that when the plunger 280 reciprocates on the second transverse stirring rod 253, the lower end of the longitudinal stirring rod 251 can extract the oil at the bottom of the tank body 225, and discharge the material from the upper end of the longitudinal stirring rod 251 after being transported by the longitudinal stirring rod 251, that is, the purpose of the oil at the bottom of the tank body 225 entering the upper oil during the stirring process is achieved, so that the device can exchange the oil in the tank body 225 up and down, thereby improving the stirring uniformity.

[0051] In addition, this embodiment has another obvious advantage, that is, the two sets of longitudinal stirring rods 251 suck and discharge materials at the same time, which can significantly increase the amount of material from the bottom of the tank reaching the top of the tank per unit time, further accelerating the mixing speed.

[0052] Specifically, refer to Figure 5 When the plunger 280 moves toward the side close to the outer main shaft 240, the lower one-way valve 260 opens and the upper one-way valve 260 closes, so that the lower end of the longitudinal stirring rod 251 absorbs oil, and the oil is temporarily stored in the second transverse stirring rod 253. When the plunger 280 moves toward the side away from the outer main shaft 240, the lower one-way valve 260 closes and the upper one-way valve 260 opens, so that the plunger 280 pushes the oil in the second transverse stirring rod 253 into the upper one-way valve 260 and discharges it from the upper end of the longitudinal stirring rod 251.

[0053] In order to realize the reciprocation of the plunger 280, as Figure 4 and Figure 5 As shown, an inner shaft 242 and a transmission assembly are also provided. The inner shaft 242 is located inside the outer main shaft 240 and rotates at unequal speeds and / or in different directions with the outer main shaft 240. A mounting box 241 is provided on the outer main shaft 240 at a position opposite to the second transverse stirring rod 253. A transmission assembly is provided in the mounting box 241. The transmission assembly is used to convert the rotational motion of the inner shaft 242 into reciprocating motion of the plunger 280, thereby realizing suction and discharge actions.

[0054] Preferably, a first transverse stirring rod 252 is further provided on the outer main shaft 240 to further improve the uniformity of stirring, and the first transverse stirring rod 252 is a solid rod-shaped structure.

[0055] like Figure 5-Figure 9As shown, specifically, the transmission assembly mentioned above includes a first transmission assembly 290. In order to facilitate the connection between the first transmission assembly 290 and the plunger 280, a plunger rod 281 is fixedly provided on one side of the plunger 280 close to the mounting box 241 for connecting the first transmission assembly 290. The first transmission assembly 290 includes a main gear plate 299, a connecting rod 296, and a support ring 295.

[0056] Specifically, the main gear plate 299 is located in the middle of the installation box 241 and is concentric with the installation box 241. The main gear plate 299 can rotate in the installation box 241. The upper and lower sides of the main gear plate 299 are provided with integrated limit plates 294. The diameter of the limit plate 294 is larger than the diameter of the main gear plate 299. The limit plate 294 is used to install the connecting rod 296 on the one hand, and to realize the shaftless installation of the main gear plate 299 on the other hand (the support ring 295 is used to support the limit plate 294).

[0057] Preferably, two groups of connecting rods 296 are provided, one end of a single connecting rod 296 is rotatably mounted at the eccentric point of one of the limit plates 294, and the other end is rotatably mounted on one of the plunger rods 281. When the main gear plate 299 rotates, the connecting rod 296 can be driven to move, so that the connecting rod 296 can drive the plunger 280 to produce reciprocating motion in the second transverse stirring rod 253.

[0058] It is worth mentioning that the main gear plate 299 needs to rotate without a shaft because once the shaft is assembled at the center of the circle, the shaft will affect the movement of the connecting rod 296, so the main gear plate 299 is set to a shaftless installation state.

[0059] Combination Figure 7-Figure 11 As shown, in order to realize the shaftless installation of the main toothed disc 299, the support ring 295 includes two groups of ring bodies 2951 arranged side by side, the ring bodies 2951 are installed in the installation box 241, and the limiting disc 294 is rotatably installed on the ring bodies 2951 through the bearing, so that the limiting disc 294 is firstly limited in the horizontal direction, so as to realize the purpose of limiting the position of the main toothed disc 299 in the horizontal direction; and in order to realize the purpose of limiting the main toothed disc 299 in the axial direction, A convex arc 2952 is also provided, and the convex arc 2952 is provided between the two ring bodies 2951. The inner diameter of the convex arc 2952 is smaller than the inner diameter of the limiting disk 294, and larger than the inner diameter of the main toothed disk 299, so that the convex arc 2952 can extend between the two limiting disks 294, but the inner wall of the convex arc 2952 does not contact the main toothed disk 299. Therefore, due to the limitation of the limiting disk 294 by the convex arc 2952 in the vertical direction, the main toothed disk 299 can be limited in the axial direction.

[0060] like Fig.10 and Fig.11As shown, since the main gear plate 299 is in a rotating state, when it drives the limit plate 294 to rotate, wear will occur between the limit plate 294 and the convex arc 2952. Therefore, preferably, ball bearings 2954 are provided on the upper and lower surfaces of the convex arc 2952, and the ball bearings 2954 are used to reduce the friction between the limit plate 294 and the convex arc 2952.

[0061] Continue to refer to Fig.10 and Fig.11 As shown, in order to realize the rotation of the main toothed disc 299, a second pinion 293, an upper toothed disc 291 and a lower toothed disc 297 are further provided. The second pinion 293 is provided with at least two (four second pinions 293 are provided in this embodiment, and the four second pinions 293 are evenly arranged on the periphery of the main toothed disc 299, see Fig.10 More intuitive), the second pinion 293 is meshed with the main gear plate 299, so that when the second pinion 293 rotates, it can drive the main gear plate 299 to rotate; in order to facilitate the installation of the second pinion 293, multiple groups of convex arcs 2952 are arranged, and an accommodating gap 2953 is formed between two adjacent convex arcs 2952, and the accommodating gap 2953 is used to accommodate the second pinion 293. The central axis of the second pinion 293 is rotatably installed on the ring body 2951 through a bearing.

[0062] Combination Figure 5-Figure 8 As shown, in order to realize the rotation of the second pinion 293, the upper toothed disc 291 is located above the limit disc 294, the inner shaft 242 is located in the upper inner section of the outer main shaft 240, the lower end of the inner shaft 242 extends into the mounting box 241 and can drive the upper toothed disc 291 to rotate, and a first pinion 292 is meshed on one side of the upper toothed disc 291, and the first pinion 292 is coaxial with the second pinion 293 which is vertically opposite, so that when the inner shaft 242 rotates, the upper toothed disc 291 can drive the first pinion 292 to rotate, and when the first pinion 292 rotates, it can synchronously drive the second pinion 293 coaxial therewith to rotate (in this embodiment, two first pinions 292 are provided, which are symmetrically provided on both sides of the upper toothed disc 291). The lower toothed disc 297 is located below the limit disc 294, and a third pinion 298 is meshed on the lower toothed disc 297. The third pinion 298 is coaxial with the second pinion 293 vertically opposite thereto, so that when the main toothed disc 299 rotates, the second pinion 293 coaxial with the third pinion 298 can also be driven to rotate, and then the third pinion 298 can drive the lower toothed disc 297 to rotate. A connecting shaft 243 is fixedly provided in the middle of the lower toothed disc 297, and the other end of the connecting shaft 243 is fixedly connected to the upper toothed disc 291 on another set of first transmission components 290, so that the device can be assembled with at least two sets of transmission components, refer to Figure 8 , namely two mounting boxes 241, two sets of transmission components, each set of transmission components is equipped with two left and right plungers 280, Figure 4The state shown is that there are four plungers 280. The two lower plungers 280 draw the oil at the bottom to the middle section of the longitudinal stirring rod 251, and the two upper plungers 280 draw the oil in the middle section of the longitudinal stirring rod 251 to the upper end of the longitudinal stirring rod 251 and discharge it, thereby avoiding the situation where insufficient suction force is caused by only one extraction.

[0063] It is worth noting that more longitudinal stirring rods 251 may be arranged outside the outer spindle 240, such as Fig.15 , four groups are set, so as to further increase the amount of material from the bottom of the tank to the top of the tank per unit time. Of course, more longitudinal stirring rods 251 need to be equipped with a one-way valve 260, a plunger 280 and a second transverse stirring rod 253, and the structure of the first transmission assembly 290 also needs to be changed. For details, refer to Fig.16 and Fig.17 As shown, two sets of main toothed discs 299 are required to be provided, and both upper and lower sides of the two sets of main toothed discs 299 are equipped with limit discs 294, that is, one first transmission assembly 290 requires four limit discs 294, and a connecting rod 296 is assembled on each limit disc 294, that is, four connecting rods 296 connect four plungers 280, and two sets of support rings 295 are also required to support the two sets of main toothed discs 299.

[0064] Combination Figure 3 , Figure 5 and Fig.12 As shown, in order to improve the mixing uniformity in the vertical direction, a longitudinal agitator 270 is provided, and the longitudinal agitator 270 includes a rotating cylinder 273 , a mounting plate 272 and an extension shaft 276 .

[0065] Specifically, the rotating cylinder 273 is a tubular structure with openings at both ends. The rotating cylinder 273 is rotatably installed on the end of the second transverse stirring rod 253 away from the installation box 241. The installation disk 272 is fixed on the end of the rotating cylinder 273 away from the installation box 241 and is exposed to the outside of the second transverse stirring rod 253. The outer arc surface of the installation disk 272 is provided with a stirring claw 271. When the rotating cylinder 273 rotates in the second transverse stirring rod 253, the installation disk 272 can drive the stirring claw 271 to rotate, so that the stirring claw 271 can stir in the vertical direction to improve the mixing uniformity.

[0066] In order to realize the automatic rotation of the rotating cylinder 273, an extension shaft 276 is also provided here. One end of the extension shaft 276 is fixed to the end of the plunger 280 away from the mounting box 241, and the other end of the extension shaft 276 extends into the rotating cylinder 273. A spiral groove 275 is provided on the outer surface of the extension shaft 276, and a slider 274 adapted to the spiral groove 275 is fixed on the inner wall of the rotating cylinder 273. Then, when the plunger 280 reciprocates, the extension shaft 276 slides therewith, and then the slider 274 can produce relative sliding in the spiral groove 275, thereby forcing the rotating cylinder 273 to rotate.

[0067] Preferably, the spiral groove 275 rotates one circle, the plunger 280 sucks the material throughout the entire stroke, and the rotating cylinder 273 rotates one circle in the forward direction. The plunger 280 discharges the material throughout the entire stroke, and the rotating cylinder 273 rotates one circle in the reverse direction.

[0068] Combination Figure 3 , Fig.12 and Fig.14 As shown, in order to increase the oil discharged from the upper end of the longitudinal stirring rod 251 to reach the surrounding area of ​​the longitudinal stirring rod 251, a guide tube 2511 is fixedly provided on the outer periphery of the upper end of the longitudinal stirring rod 251, and a reserved space is provided between the inner wall of the guide tube 2511 and the outer wall of the longitudinal stirring rod 251, and guide pipes 2512 connected to the reserved space are provided on both sides of the guide tube 2511, and a leakage hole 2513 is opened on the bottom surface of the guide pipe 2512.

[0069] In this embodiment, after the oil is discharged from the upper end of the longitudinal stirring rod 251, the oil actually reaches the guide tube 2511 and can enter the guide tube 2512, then flows along the guide tube 2512, and finally is discharged from the leakage hole 2513. In essence, the guide tube 2512 and the leakage hole 2513 form a liquid distributor, which increases the area of ​​the extracted oil returning to the oil, thereby improving the uniformity of the mixing.

[0070] In order to realize the division of labor between the outer spindle 240 and the inner shaft 242, a driving assembly 210 is also provided here. The driving assembly 210 is used to drive the outer spindle 240 and the inner shaft 242 to rotate at unequal speeds and / or in different directions. This is because once the outer spindle 240 and the inner shaft 242 rotate synchronously, the plunger 280 will not be able to work.

[0071] The following takes the example of the drive component 210 driving the outer main shaft 240 and the inner shaft 242 to rotate in different directions. The drive component 210 includes a driven umbrella wheel 215 fixed to the upper end of the outer main shaft 240, an active umbrella wheel 213 fixed to the upper end of the inner shaft 242, and a transmission umbrella wheel 214 meshed on one side of the driven umbrella wheel 215 and the active umbrella wheel 213. Then, the outer main shaft 240 and the inner shaft 242 can rotate in different directions. A drive motor 211 that can drive the inner shaft 242 to rotate is also provided at the upper end of the inner shaft 242, and the drive motor 211 is assembled on the bracket 212, and the transmission umbrella wheel 214 is also assembled on the bracket 212.

[0072] Preferably, in order to achieve the required temperature during blending, a heating jacket 224 is provided at the lower portion of the tank body 225 , and the heating jacket 224 is used to heat the inside of the tank body 225 . Preferably, the heating jacket 224 is an electric heating structure.

[0073] Preferably, an oil inlet 221 and a blending additive inlet 222 are provided above the tank body 225, an oil drain port 223 is provided at the lower part of the tank body 225, the oil drain pipe of the base tank 1 is fixedly connected to the oil inlet 221, the oil drain port 223 is connected to the oil inlet pipe of the filter 3, and the oil drain pipe of the filter 3 is connected to the oil inlet pipe of the finished oil tank 4.

[0074] In addition, a solenoid valve should be provided on the oil discharge port 223 .

[0075] When in use (working), the base oil is pumped from the inside of the base tank 1 into the inside of the blending tank 2, and the required additives are fed into the blending tank 2 through the blending additive inlet 222, and the oil is heated by the heating sleeve 224. When the driving motor 211 is working, the outer main shaft 240 and the inner shaft 242 work. When the outer main shaft 240 rotates, it can drive the second transverse stirring rod 253, the first transverse stirring rod 252 and the longitudinal stirring rod 251 to rotate, so that the three act as stirring blades to mix the base oil and the additive. At the same time, the inner shaft 242 drives the upper toothed disc 291 to rotate, thereby driving the main toothed disc 299 to rotate through the action of the first pinion 292. When the main toothed disc 299 rotates, it can push and pull the plunger 280 through the action of the connecting rod 296. When the plunger 280 moves toward the side close to the outer main shaft 240, the plunger 2 The one-way valve 260 below 80 is opened, and the one-way valve 260 above the plunger 280 is closed, so that the lower end of the longitudinal stirring rod 251 absorbs oil, and the oil is temporarily stored in the second transverse stirring rod 253. When the plunger 280 moves toward the side away from the outer main shaft 240, the one-way valve 260 below is closed, and the one-way valve 260 above is opened, so that the plunger 280 pushes the oil in the second transverse stirring rod 253 into the one-way valve 260 above and discharges it from the upper end of the longitudinal stirring rod 251. After the oil is discharged from the upper end of the longitudinal stirring rod 251, the oil actually reaches the guide tube 2511 and can enter the guide pipe 2512, then flows along the guide pipe 2512, and finally is discharged from the leakage hole 2513. In essence, the guide pipe 2512 and the leakage hole 2513 form a liquid distributor, which increases the area of ​​the extracted oil returning to the oil and improves the uniformity of the mixing.

[0076] Embodiment 2: This embodiment refers to Fig.18 .

[0077] The difference between this embodiment and the first embodiment is that the transmission assembly includes a second transmission assembly 230 , and the second transmission assembly 230 includes a cam 231 , a pressure rod 232 , a guide frame 234 and a spring 233 .

[0078] The cam 231 is located in the mounting box 241 and is concentric with the mounting box 241. The inner shaft 242 is fixed at the center of the cam 231. When the inner shaft 242 rotates, it can drive the cam 231 to rotate. One end of the pressure rod 232 is fixed on the plunger 280, and the other end of the pressure rod 232 is close to the cam 231. The guide frame 234 is fixed at one end of the second transverse stirring rod 253 close to the mounting box 241. The pressure rod 232 is slidably set on the guide frame 234, and the spring 233 is sleeved on the pressure rod 232.

[0079] In this embodiment, when the inner shaft 242 rotates, the cam 231 can be directly driven to rotate. When the raised part of the cam 231 rotates to the position of the pressure rod 232, it can push the pressure rod 232 and compress the spring 233, so that the pressure rod 232 pushes the plunger 280. Conversely, when the raised part of the cam 231 disengages from the pressure rod 232, the spring 233 rebounds, causing the plunger 280 to reset.

[0080] It is worth noting that the structure in this embodiment is relatively simple in overall structure compared to the structure in embodiment one, but the maximum stroke of the plunger 280 in this embodiment is smaller than the maximum stroke in embodiment one, so the single extraction amount is smaller than the single extraction amount in embodiment one.
