Description

Technical Field

[0001] The utility model relates to the field of lubricating oil processing, in particular to a lubricating oil base oil heating device. Background Art

[0002] The base oil of lubricating oil refers to one of the main ingredients used to make lubricating oil, usually mineral oil, synthetic oil or vegetable oil. These base oils are mixed or processed to meet the needs of different types and uses of lubricating oil. Mineral oil is extracted from petroleum, while synthetic oil is obtained through chemical synthesis or processing. Vegetable oil is a natural oil extracted from plants. Choosing different types of base oils can give lubricating oils different performance characteristics, such as high temperature resistance, oxidation resistance, wear resistance, etc.

[0003] The purpose of heating lubricant base oil is to improve its fluidity and handling properties. When the base oil is heated, its viscosity decreases, which makes it easier to mix with additives and easier to process and blend during production. In addition, heating the base oil can also volatilize impurities and moisture in it, thereby improving the purity and quality of the lubricant. When producing lubricants, heating the base oil also helps ensure that the stability and performance of the final product meet expectations.

[0004] At present, the existing lubricating oil base oil heating device is prone to uneven heating during the heating process due to the distribution of heating components, which may cause temperature differences inside the base oil, resulting in uneven mixing, making the performance of the lubricating oil unstable, and even affecting its basic function. Therefore, there is an urgent need for a lubricating oil base oil heating device that can heat evenly. Utility Model Content

[0025] like Figure 1-Figure 4As shown, a lubricating oil base oil heating device comprises an outer shell 1, an inner shell 2 is fixedly installed inside the outer shell 1, the inner shell 2 is hollow cylindrical, and a valve for discharging lubricating oil is opened at the bottom, a first motor 3 is fixedly installed on the back of the outer shell 1, the output end of the first motor 3 is connected to a first rotating shaft 4, the first rotating shaft 4 rotatably passes through the outer shell 1 and the inner shell 2, and a plurality of groups of stirring blades 5 are fixedly installed on the outer wall inside the inner shell 2, a second motor 6 is fixedly installed on the side end of the outer shell 1, the output end of the second motor 6 is connected to a second rotating shaft 7, the second rotating shaft 7 rotatably passes through the outer shell 1 and the inner shell 2, and is located inside the inner shell 2 A rotating disk 8 is fixedly installed on the outer wall of the device, and the lubricating base oil entering the device is stirred by arranging multiple stirring steps inside the device. First, two sets of parallel stirring blades 5 are used to stir the base oil, and the stirred base oil falls onto the rotating disk 8. The base oil is stirred again by the rotation of the rotating disk 8. Since the stirring directions of the rotating disk 8 and the stirring blades 5 are different, the base oil can be fully stirred and evenly heated, which solves the problem of uneven heating due to the distribution of heating components in the prior art, resulting in temperature differences inside the base oil and unstable performance of the lubricating oil.

[0026] In some embodiments, a first pulley 9 is fixedly installed on the outer wall of the first rotating shaft 4 located outside the outer shell 1, and is connected to the second pulley 10 through a belt and transmission. The second pulley 10 is fixedly installed on the third rotating shaft 11. When stirring, the first motor 3 is started to drive the first rotating shaft 4 to rotate, and the third rotating shaft 11 is driven to rotate synchronously through the cooperation of the first pulley 9, the second pulley 10 and the belt, so that the stirring blades 5 of the first rotating shaft 4 and the third rotating shaft 11 rotate inside the inner shell 2 to stir the base oil.

[0027] In some embodiments, the first rotating shaft 4 and the third rotating shaft 11 are arranged in parallel with a gap therebetween, so that the base oil can be initially stirred without any motion interference.

[0028] In some embodiments, the diameter of the rotating disk 8 is set to be smaller than the diameter of the inner shell 2, so that when the rotating disk 8 rotates, its edge will not interfere with the inner wall of the inner shell 2 in movement, affecting the stirring of the base oil by the rotating disk 8. At the same time, a plurality of groups of holes are opened through the top surface of the rotating disk 8, so that the base oil can flow through the holes during stirring, and it can also play an auxiliary stirring role when the rotating disk 8 rotates, so that the base oil can be repeatedly stirred multiple times at the same time, thereby improving the stirring effect and efficiency. In addition, the diameter of the rotating disk 8 is set to be smaller than the minimum distance between the stirring blade 5 and the bottom surface of the inner shell 2, so that the rotating disk 8 will not collide with the stirring blade 5 above when stirring the base oil, thereby ensuring the safety of the operation of the device.

[0029] In some embodiments, a plurality of groups of heating rods 12 are distributed in an array around the inner circumference of the inner shell 2 to heat the base oil inside the inner shell 2 .

[0030] Working principle: When in use, the base oil is sent into the inner shell 2 through the pipe at the top of the device. At this time, the heating rod 12 is turned on to heat the inner shell 2, and then the first motor 3 is started, the first rotating shaft 4 rotates, driving the stirring blade 5 on its outer wall to rotate, and at the same time, with the cooperation of the first pulley 9 and the second pulley 10 and the belt, the third rotating shaft 11 is synchronously driven to rotate to perform preliminary stirring of the base oil. The base oil that has been initially stirred falls to the top surface of the rotating disk 8. At this time, the second motor 6 is started, the second rotating shaft 7 rotates, driving the rotating disk 8 to rotate, and the base oil is stirred again. At the same time, the base oil is stirred multiple times with the auxiliary stirring of the holes on the rotating disk 8 to improve the stirring effect. After the heating and stirring are completed, the base oil is discharged from the valve at the bottom of the inner shell 2.

[0031] The first motor, the second motor, the first pulley, the second pulley and the heating rod are all universal standard parts or are known through conventional experimental methods, so they are not described in detail here.

[0032] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
