Description

Technical Field

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

[0002] Lubricating oil is a functional liquid applied between two relatively moving objects, which can reduce the friction and wear generated by the contact of the two objects. 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 roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. When lubricating oil is produced, it needs to be heated. Usually, a large-capacity storage tank is used for centralized heating. When specifically heating, an electric heating tube or an electric heating wire gradually heats the lubricating oil from the bottom of the storage tank, resulting in slow heating effect. And because the lubricating oil is directly heated, due to the small heating point of the lubricating oil, the lubricating oil is heated unevenly, and at the same time, it may cause the local temperature of the lubricating oil to be too high, damaging the components of the lubricating oil and reducing the service life of the lubricating oil. For this reason, we propose a lubricating oil heating device. Content of the Utility Model

The flow guide plate 8 can play a role in gathering water vapor, and the oil storage tank 2 can increase the contact area with water vapor. And the flow guide plate 8 and the bottom of the heating main body 1 form a water storage cavity 11 for storing water. A water injection hole 5 is opened on the outer side of the top of the water storage cavity 11. Through the water injection hole 5, water can be injected into the water storage cavity 11. An oil injection hole 3 communicating with the oil storage tank 2 is opened at the top of the heating main body 1, enabling the lubricating oil to be smoothly injected into the oil storage tank 2. And under normal circumstances, the oil injection hole 3 and the water injection hole 5 are plugged to facilitate the storage of the lubricating oil. At the same time, an oil outlet pipe 6 is fixedly connected to the bottom of the oil storage tank 2. The oil outlet pipe 6 is connected to the outside, enabling the lubricating oil to be smoothly discharged.

[0024] Please refer to Figures 1 to 5 , an electromagnetic valve 19 is installed in the oil outlet pipe 6. Through the electromagnetic valve 19, the lubricating oil can enter the oil outlet pipe 6 or be stored in the oil storage tank 2. A partition plate 7 is fixedly connected to the top of the outside of the flow guide plate 8.
