[0001] The utility model relates to the technical field of lubricating oil heating and dehydration, specifically to an HP-8B lubricating oil heating and dehydration mechanism. Background Art

[0002] The presence of moisture in lubricating oil will directly affect the appearance of the product, cause hydrolysis and precipitation of additives in the lubricating oil, resulting in the failure of additives and reduction of their use functions. Moisture will reduce the viscosity of the oil product, reduce the load-bearing capacity of the oil film, and even damage the oil film and cause mechanical part wear. Using the principle that the vaporization temperature of water is lower than that of oil, the oil is heated in a closed container and evacuated, so that the water vapor in the oil is vaporized and evacuated. This method can remove free water, emulsified water and dissolved water.

[0026] In this embodiment, an inclined cavity is formed inside the drainage pipe 4, and the inner wall of the inclined cavity of the drainage pipe 4 is coated with a glass coating to guide the lubricating oil and water out in an inclined manner.

[0027] In this embodiment, vertical shafts 15 are fixedly arranged around the bottom end of the pressing plate 12. The vertical shafts 15 penetrate through the filter sponge 13 and the support plate 14, and the vertical shafts 15 are slidably arranged with the filter sponge 13 and the support plate 14. The pressing plate 12 moves up and down around the support plate 14 through the vertical shafts 15.

[0028] In this embodiment, a telescopic shaft 17 is fixedly arranged at the bottom end of the support plate 14, and the other end of the telescopic shaft 17 is fixedly arranged with the extrusion box 7. A spring 18 is sleeved outside the telescopic shaft 17, and the spring 18 is located between the support plate 14 and the telescopic shaft 17. The telescopic shaft 17 pushes the support plate 14 to rise through the outer spring 18 to maintain the position of docking with the drainage pipe 4.

[0031] Embodiment 2

[0032] As Figure 4As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a housing 20 is fixedly arranged on the left side of the heating tank 1.

[0034] Working process:

[0035] The staff adds HP-8B lubricating oil into the interior of the heating tank 1 through the adding pipe. Through the heating plate 2 and the heating structure arranged inside the heating tank 1, the HP-8B lubricating oil is heated. Water first evaporates and is converted into a gaseous state and enters the interior of the connecting pipe 3, and is drained into the output pipe 5 through the drainage pipe 4 and then drained into the interior of the collection tank 6. At the same time, the filter sponge 13 inside the extrusion box 7 will recover the HP-8B lubricating oil and part of the water to prevent them from flowing into the interior of the collection tank 6 again. After dehydration is completed, the water flow switch of the collection tank 6 is opened to drain the water condensed from the water vapor inside. The motor 9 works to drive the threaded shaft 10 at the end of the main shaft to rotate, pushing the extrusion filter sponge 13 to compress and deform, so as to squeeze out the HP-8B lubricating oil and water in the filter sponge 13. At the same time, the bottom support plate 14 is pushed to cooperate with the vertical shaft 15 to stably move in one direction, and the support plate 14 is pushed to squeeze the telescopic shaft 17 and the spring 18 to contract, controlling the HP-8B lubricating oil and water to enter the interior of the lower pipe 8, and opening the one-way valve to drain the HP-8B lubricating oil and a small amount of water into the collection tank 6 for secondary heating and dehydration to reduce the waste of resources of the HP-8B lubricating oil. After the HP-8B lubricating oil is heated, the floating plate 23 floating above the liquid surface closes the liquid surface, accelerating the speed of heat increase, and guiding and discharging the steam neatly through the gaps of the floating plate 23, accelerating the heating efficiency.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
