Description

Technical Field

[0001] This application relates to the technical field of lubricating oil production, and specifically to a lubricating oil blending device. Background Art

[0002] Lubricating oil is a complex mixture of hydrocarbons, which mainly includes base oil and additives. The variety and quantity of additives also determine the performance of lubricating oil. Therefore, in order to meet the application requirements of different mechanical fields, corresponding additives need to be added to the base oil, and the base oil and additives are stirred and blended into lubricating oil.

[0003] Chinese Patent Authorization Publication No.: CN221062393U discloses a blending device for lubricating oil production, belonging to the technical field of lubricating oil blending devices. This solution stirs in two directions to expand the mixing area of the base oil and additives, making the base oil and additives evenly mixed. At the same time, it speeds up the mixing speed of the base oil and the blending agent and shortens the blending time.

[0004] However, when there is a large amount of lubricating oil raw materials to be processed inside the blending tank, due to possible limitations in stirring capacity, mixing time, or mixing method, it takes a long time to fully mix the lubricating oil raw materials. Since the lubricating oil can only be discharged after being blended, during the process of waiting for the raw materials in the blending tank to be fully blended, other equipment on the production line has to be idle, resulting in an increase in idle time on the production line, thereby reducing the utilization rate of the equipment and the overall production capacity.

[0005] Therefore, it is necessary to provide a lubricating oil blending device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Utility Model Content

Once the blending is completed, the lubricating oil in the stirring cylinder can be smoothly discharged through the discharge pipe, so as to facilitate the processing of the next process, without waiting for all the mixed raw materials in the blending tank to be evenly blended, improving the discharge efficiency of the lubricating oil, reducing the downtime of subsequent production equipment, and improving the utilization rate of the equipment and the overall production capacity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-5 shown, the present application provides a lubricating oil blending device, including: a blending tank 1, a feeding mechanism 3, and a stirring mechanism 4. An inlet pipe 5 is installed at the top of the blending tank 1 for adding base oil and additives into the blending tank 1. A plurality of support frames 2 are installed at the bottom of the blending tank 1, and the plurality of support frames 2 are fixed to the bottom of the blending tank 1 by welding. The feeding mechanism 3 includes a stirring cylinder 31. A connecting pipe 33 is installed at the top of the stirring cylinder 31, and the stirring cylinder 31 is connected to the blending tank 1 through the connecting pipe 33. Both ends of the connecting pipe 33 are fixed to the blending tank 1 and the stirring cylinder 31 by welding. A first solenoid valve is installed on the connecting pipe 33. A discharge pipe 34 communicating with the outside of the stirring cylinder 31 is installed on the outer side wall of the stirring cylinder 31, and a second solenoid valve is installed on the discharge pipe 34. The stirring mechanism 4 includes a motor 41 installed on the top of the blending tank 1. The 41 is fixed to the top of the blending tank 1 by bolts. A stirring rod 42 is installed at the output end of the motor 41. A plurality of first stirring blades 43 are installed on the outer side wall of the stirring rod 42 and inside the blending tank 1, and a plurality of second stirring blades 44 are installed on the outer side wall of the stirring rod 42 and inside the stirring cylinder 31.

[0030] In this embodiment, the present solution is a device for stirring and blending base oil and additives into lubricating oil. Specifically, the base oil and additives are added into the blending tank 1, and the mixed raw materials in the blending tank 1 are discharged into the lower stirring cylinder 31 in batches through a pair of connecting pipes 33, reducing the capacity of the mixed raw materials for a single stirring and blending process. The provided stirring mechanism 4 can stir and blend the raw materials inside both the blending tank 1 and the stirring cylinder 31 at the same time. Since the amount of raw materials in the stirring cylinder 31 is less, the stirring resistance of the stirring mechanism 4 is reduced, and the stirring efficiency is improved, so as to quickly blend the raw materials in the stirring cylinder 31, and the blended raw materials in the stirring cylinder 31 are discharged through the discharge pipe 34, facilitating the processing of the next process, without waiting for all the mixed raw materials in the blending tank 1 to be evenly blended, and improving the discharge efficiency of the lubricating oil.

[0031] As Figures 1-2As shown, the capacity of the blending tank 1 is much larger than that of the mixing drum 31.

[0032] In this embodiment, by discharging the raw materials in the large-capacity blending tank 1 into the smaller-capacity mixing drum 31 in batches, the discharging speed of the raw materials in the mixing drum 31 can be increased.

[0033] As Figure 4 shown, a connecting frame 32 connected to it is installed on the outer side wall of the mixing drum 31. A sliding rod 36 is installed inside the connecting frame 32. The sliding rod 36 is fixed to the inside of the connecting frame 32 by welding. A floating ball 37 is slidably connected to the sliding rod 36. A pair of trigger blocks 38 are installed on the outer side wall of the floating ball 37. A first induction switch 35 is installed at the top end of the inner wall of the connecting frame 32, and a second induction switch 39 is installed at the bottom end of the inner wall of the connecting frame 32.

[0034] In the embodiment, the first solenoid valve on the connecting pipe 33 and the second solenoid valve on the discharge pipe 34 are both controlled by a controller. When the raw materials in the blending tank 1 are discharged into the mixing drum 31 through the connecting pipe 33, the floating ball 37 slides upward on the sliding rod 36 under the action of buoyancy as the oil level rises. When the floating ball 37 on the outer side wall of the sliding rod 36 contacts the upper first induction switch 35, the first induction switch 35 is squeezed and gives feedback. The controller controls the first solenoid valve on the connecting pipe 33 to close, and the stirring mechanism 4 is used to fully stir and mix the raw materials in the mixing drum 31. However, the second solenoid valve on the discharge pipe 34 is automatically opened at a set time. At this time, the blended lubricating oil inside the mixing drum 31 is discharged through the discharge pipe 34 for the next process. At the same time, the floating ball 37 drops as the oil level decreases. When all the lubricating oil in the mixing drum 31 is discharged, the trigger block 38 on the outer side wall of the floating ball 37 contacts the lower second induction switch 39. The second induction switch 39 is squeezed and gives feedback. The controller is used to control the second solenoid valve on the discharge pipe 34 to automatically close and at the same time open the first solenoid valve on the connecting pipe 33, so that the raw materials in the blending tank 1 are discharged into the mixing drum 31 through the connecting pipe 33 again.

[0035] It should be noted that the floating ball 37 is filled with a light material, such as foam, to reduce the overall density of the floating ball 37 and make the floating ball 37 less dense than the oil, so as to achieve floating.

[0036] As Figures 4-5As shown in the figure, a plurality of vibration mechanisms 6 are installed at the bottom of the blanking mechanism 3. The vibration mechanism 6 includes a rotating shaft 61, the rotating shaft 61 is rotatably connected to the bottom of the mixing drum 31, and a driven gear 62 is installed at one end of the rotating shaft 61 away from the mixing drum 31. The driven gear 62 is fixed to the outer side wall of the rotating shaft 61 by welding. One end of the stirring rod 42 away from the motor 41 is installed with a driving gear 45. The driving gear 45 is fixedly sleeved at the end of the stirring rod 42. The driving gear 45 is meshed with the driven gear 62. The vibration mechanism 6 further includes a connecting rod 63. The connecting rod 63 is rotatably connected to the bottom of the mixing drum 31. The connecting rod 63 is rotatably connected to the bottom of the mixing drum 31 by means of a pin shaft to ensure the rotation of the driven gear 62, so that the impact ball 65 can impact the bottom of the mixing drum 31. One end of the connecting rod 63 away from the mixing drum 31 is installed with an impact ball 65. The impact ball 65 is fixedly connected to the connecting rod 63 by welding. The impact ball 65 abuts against the top of the driven gear 62. A plurality of convex blocks 64 are arranged at equal intervals in a ring shape on the top of the driven gear 62. The cross section of the convex block 64 is semicircular.

[0037] In this embodiment, when the stirring rod 42 rotates, it drives the driving gear 45 at the bottom to rotate. Under the meshing connection of the driving gear 45 and a plurality of driven gears 62, a plurality of driven gears 62 are synchronously driven to rotate. When the convex block 64 on the top of the driven gear 62 contacts the impact ball 65, the impact ball 65 will move upward under extrusion, so that the impact ball 65 impacts the bottom of the mixing drum 31. When the impact ball 65 is located between two adjacent convex blocks 64, the impact ball 65 contacts the top of the driven gear 62 again under the action of gravity. With the continuous rotation of the driven gear 62, the purpose of the impact ball 65 reciprocally impacting the bottom of the mixing drum 31 can be realized, so that the mixing drum 31 generates resonance, and the probability of lubricating oil adhering to the inner wall of the mixing drum 31 during the blanking process is reduced.

[0038] Working principle:

[0039] By adding base oil and additives into the blending tank 1 and discharging the mixed raw materials in the blending tank 1 into the stirring cylinder 31 below in batches. Additionally, the stirring mechanism 4 can stir and blend the raw materials inside both the blending tank 1 and the stirring cylinder 31 simultaneously. When the raw materials in the blending tank 1 are discharged into the stirring cylinder 31 through the connecting pipe 33, the float ball 37 slides upward on the sliding rod 36 under the action of buoyancy as the oil level rises. When the float ball 37 on the outer sidewall of the sliding rod 36 contacts the first induction switch 35 located above, the first induction switch 35 is squeezed and gives feedback. The first electromagnetic valve on the connecting pipe 33 is controlled by the controller to close. The stirring mechanism 4 is used to fully stir and mix the raw materials in the stirring cylinder 31. However, the second electromagnetic valve on the discharge pipe 34 is automatically opened at a set time. At this time, the lubricating oil after blending inside the stirring cylinder 31 is discharged through the discharge pipe 34 to carry out the next process. Meanwhile, the float ball 37 descends as the oil level drops. When all the lubricating oil in the stirring cylinder 31 is discharged, the trigger block 38 on the outer sidewall of the float ball 37 contacts the second induction switch 39 located below. The second induction switch 39 is squeezed and gives feedback. The controller is used to control the second electromagnetic valve on the discharge pipe 34 to automatically close and simultaneously open the first electromagnetic valve on the connecting pipe 33, so that the raw materials in the blending tank 1 are discharged into the stirring cylinder 31 through the connecting pipe 33 again, and the above operations are repeated to improve the discharging efficiency of the lubricating oil.

[0040] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
