[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. As long as it is applied between two objects in relative motion and can reduce the friction and wear caused by contact between the two objects, it is a lubricating oil.

In view of this, we propose a lubricating oil heating device to solve the above problems. Utility Model Content

[0024] Wherein, a supporting assembly for supporting the device is arranged below the mounting cover 12 .

[0025] See also Figure 3 , Figure 4 and Figure 5 A heating assembly for heating the lubricating oil is arranged inside the mounting cover 12, and the heating assembly includes an electric heating wire 3 fixedly mounted on the surface of the heating cylinder 2. The interior of the mounting cover 12 is also filled with heat transfer oil for transferring heat. A plurality of stirring plates 15 for stirring the heat transfer oil are fixedly mounted on the inner wall of the mounting cover 12, and a plurality of fine holes 16 are opened on the surface of the stirring plates 15. A gear ring 4 is fixedly mounted on the surface of the mounting cover 12, and a driving assembly for driving the gear ring 4 to rotate is also arranged on the surface of the supporting assembly.

[0026] Among them, by arranging a mounting cover 12 on the outside of the heating tube 2, the electric heating wire 3 can heat the lubricating oil while also heating the heat transfer oil inside the mounting cover 12. At the same time, the mounting cover 12 is driven to rotate by the driving device. During the rotation of the mounting cover 12, the stirring plate 15 will drive the heat transfer oil to turn inside the mounting cover 12, so that the outer wall of the heating tube 2 is heated more evenly. In addition, the double heating can also greatly improve the efficiency of heating the lubricating oil.

[0027] In addition, by opening a plurality of fine holes 16 on the surface of the stirring plate 15 , the heat transfer oil is not likely to remain on the inner side of the stirring plate 15 , so that the heat transfer oil can be easily removed later.

[0028] In this embodiment, a discharge pipe 10 connected to the heating cylinder 2 is fixedly installed on the side of the fixed plate 1 away from the heating cylinder 2, and a feed pipe 9 is fixedly installed on the side of the heating cylinder 2 away from the fixed plate 1. Sealing covers are installed at the pipe openings of the feed pipe 9 and the discharge pipe 10. The support assembly includes two support frames 13 fixedly installed at the bottom of the discharge pipe 10 and the feed pipe 9 respectively, and a base 14 is fixedly installed at the bottom of the support frame 13.

[0029] In this embodiment, the driving assembly includes a motor 5 fixedly mounted on the top of the base 14 , and a gear 6 is fixedly mounted on the output end of the motor 5 , and the gear 6 is meshed with the gear ring 4 .

[0030] The starter motor 5 drives the gear 6 to rotate, thereby causing the mounting cover 12 to rotate through the gear ring 4 .

[0031] In this embodiment, the electric heating wire 3 is spirally wound on the outside of the heating tube 2, the stirring plate 15 is arranged in an L shape, and the first sealing sleeve 7 is rotatably installed on the side of the fixed plate 1 close to the heating tube 2 through a bearing, the outer wall of the mounting cover 12 is fixed to the inner wall of the first sealing sleeve 7, and the second sealing sleeve 8 is fixedly installed on the side of the mounting cover 12 away from the fixed plate 1, and the outer wall of the heating tube 2 is rotatably connected to the inner wall of the second sealing sleeve 8.

[0032] Among them, the sealing between the fixing plate 1 and the mounting cover 12 is ensured by the first sealing sleeve 7, and the sealing between the heating tube 2 and the mounting cover 12 is ensured by the second sealing sleeve 8, so that the heat transfer oil is not easy to leak.

[0033] In addition, an oil inlet pipe and an oil outlet pipe for adding and removing heat transfer oil are also installed on the surface of the mounting cover 12.

[0034] In this embodiment, an exhaust pipe 11 connected to the mounting cover 12 is fixedly mounted on the surface of the fixed plate 1, a valve is mounted on the surface of the exhaust pipe 11, a temperature sensor 17 for detecting the temperature of the heat transfer oil is fixedly mounted on the outside of the heating cylinder 2, and a controller 18 is fixedly mounted on one side of the fixed plate 1.

[0035] The motor 5 , the electric heating wire 3 and the temperature sensor 17 are all electrically connected to the controller 18 through wires. A display is installed on the surface of the controller 18 , and the display can display the temperature detected by the temperature sensor 17 .

[0036] In addition, the model of the controller 18 may be S7-1200 PLC, etc., and may also be changed according to actual needs. This is prior art and will not be described in detail here.

[0037] When the present embodiment is in use, the lubricating oil to be heated is added through the feed pipe 9 and placed into the interior of the heating tube 2, and the electric heating wire 3 is started to heat the outer wall of the heating tube 2. The electric heating wire 3 spirally wound around the outer wall of the heating tube 2 can make the lubricating oil heated more evenly. At the same time, the electric heating wire 3 can also heat the heat-conducting oil inside the mounting cover 12. The motor 5 is started to drive the gear 6 to rotate, thereby rotating the mounting cover 12 through the gear ring 4. During the rotation of the mounting cover 12, the stirring plate 15 will drive the heat-conducting oil to flip inside the mounting cover 12, thereby making the outer wall of the heating tube 2 heated more evenly. In addition, the double heating can also greatly improve the efficiency of the heating of the lubricating oil. After the heating is completed, the discharge pipe 10 is opened to take out the heated heat-conducting oil.
