[0016] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0017] 1. The utility model is provided with a stirring mechanism. Through the output of the servo motor, the active bevel gear drives the bevel gear ring and the driven bevel gear to rotate. At this time, the installation pipe and the water filter box rotate with the bevel gear ring. As the driven bevel gear rotates, the connecting shaft drives the stirring rod to rotate synchronously, and stirs the lubricating oil in the inner cavity of the water filter box, so that it quickly passes through the surface of the water filter box and contacts with the hydrophilic oleophobic film. Due to the characteristics of the hydrophilic oleophobic film, the lubricating oil passing through its surface can be blocked, and the water will be filtered out of the hydrophilic oleophobic film and flow into the inner cavity of the box, thereby completing the dehydration of the lubricating oil, effectively preventing the lubricating oil from oxidizing and deteriorating due to the presence of water in the lubricating oil, extending the service life of the lubricating oil, and reducing the lubricating oil consumption.

The heating wire can be arranged to heat the temperature in the inner cavity of the box, so that the temperatures of the water and the lubricating oil in the inner cavity of the water filter box are increased synchronously. At the same time, since the boiling point of water is different from that of the lubricating oil, the water temperature can quickly reach the boiling point and start to vaporize, so that the density of water is reduced again, so that it is convenient to discharge into the inner cavity of the box through the hydrophilic oleophobic membrane. The temperature display panel and the temperature sensing probe are arranged to facilitate the observation of the temperature in the inner cavity of the box, so as to avoid the temperature being too high or too low, thereby affecting the vaporization of water and causing the hydrophilic oleophobic membrane to have a low efficiency in separating water and lubricating oil.

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, the embodiment of the present utility model provides a lubricating oil efficient dehydration and purification device, comprising a box body 1, a box cover 3 is provided on the top of the box body 1, the top of the box cover 3 is connected to an oil inlet pipe 4, an L-shaped plate 5 is fixedly installed on the bottom of the box body 1, a bottom plate 11 is fixedly installed on the bottom of the box body 1, and anchor bolts 12 are threadedly connected around the top of the bottom plate 11, and a drain port 13 is opened at the bottom of the inner cavity of the box body 1;

[0031] A stirring mechanism 2 is provided in the inner cavity of the box body 1, and the stirring mechanism 2 includes a servo motor 201, a mounting tube 204 and a connecting shaft 207. The servo motor 201 is fixedly installed on the left side of the L-shaped plate 5, the mounting tube 204 is arranged at the bottom of the inner cavity of the box body 1, the top of the mounting tube 204 is fixedly connected to the water filter box 205, the connecting shaft 207 is arranged at the bottom of the box body 1, and the surface of the connecting shaft 207 is fixedly installed with a stirring rod 208. The output end of the servo motor 201 is fixedly connected to the active bevel gear 202, the bottom of the mounting tube 204 is fixedly installed with a bevel gear ring 203, and the bottom of the connecting shaft 207 is fixedly installed with a driven bevel gear 206. The surfaces of the driven bevel gear 206 and the bevel gear ring 203 are both in contact with the active bevel gear The surfaces of the movable bevel gear 202 are meshed with each other, and a movable groove 209 is provided at the bottom of the box body 1. The mounting tube 204 passes through the inner cavity of the movable groove 209 and extends into the inner cavity of the box body 1. The surface of the mounting tube 204 is movably connected to the inner cavity of the movable groove 209 through a bearing. A plug-in groove 210 is provided at the bottom of the water filter box 205. The connecting shaft 207 passes through the inner side of the mounting tube 204 and the inner cavity of the plug-in groove 210 and extends into the inner cavity of the water filter box 205. The surfaces of the driven bevel gear 206 are movably connected to the inner side of the mounting tube 204 and the inner cavity of the plug-in groove 210 through a bearing. A first cavity 211 is provided on the inner surface of the water filter box 205, and a hydrophilic and oleophobic membrane 212 is fixedly installed in the inner cavity of the first cavity 211.

[0032] By setting up the stirring mechanism 2, through the output of the servo motor 201, the active bevel gear 202 drives the bevel gear ring 203 and the driven bevel gear 206 to rotate, and at this time the installation tube 204 and the water filter box 205 rotate along with the bevel gear ring 203, and with the rotation of the driven bevel gear 206, the connecting shaft 207 drives the stirring rod 208 to rotate synchronously, and stirs the lubricating oil in the inner cavity of the water filter box 205, so that it quickly passes through the surface of the water filter box 205 and contacts with the hydrophilic and oleophobic membrane 212. The characteristics of the hydrophilic oleophobic membrane 212 can block the lubricating oil passing through its surface, and the water will be discharged after being filtered by the hydrophilic oleophobic membrane 212 and flow into the inner cavity of the box body 1, thereby completing the dehydration of the lubricating oil, effectively preventing the lubricating oil from oxidizing and deteriorating due to the presence of water in the lubricating oil, extending the service life of the lubricating oil, and reducing the lubricating oil consumption. By setting up the hydrophilic oleophobic membrane 212, the lubricating oil and water in the inner cavity of the water filter box 205 can be separated, thereby purifying the lubricating oil.

[0033] Example 2

[0034] like Figure 1 and Figure 2As shown, in one embodiment, fixing bolts 6 are threadedly connected on all four sides of the top of the box cover 3, and the bottoms of the six fixing bolts 6 are threadedly connected to the inner surface of the box body 1. A second cavity 7 is opened on the inner surface of the box body 1, and a heating wire 8 is fixedly installed on the inner surface of the second cavity 7. A temperature sensing probe 9 is fixedly installed on the front side of the bottom of the inner cavity of the box body 1, and a temperature display panel 10 is fixedly installed on the front side of the box body 1.

[0035] By setting the fixing bolts 6, the box cover 3 can be disassembled, so that the lubricating oil can be extracted from the inner cavity of the water filter box 205 after purification is completed. By setting the heating wire 8, the temperature in the inner cavity of the box body 1 can be heated, so that the temperatures of the water and lubricating oil in the inner cavity of the water filter box 205 rise synchronously. At the same time, since the boiling point of water is different from that of the lubricating oil, the water temperature can quickly reach the boiling point and begin to vaporize, so that the density of the water is reduced again, so that it is convenient to be discharged into the inner cavity of the box body 1 through the hydrophilic and oleophobic membrane 212. By setting the temperature display panel 10 and the temperature sensing probe 9, the temperature in the inner cavity of the box body 1 can be observed conveniently to avoid the temperature being too high or too low, thereby affecting the vaporization of water and causing the hydrophilic and oleophobic membrane 212 to have a low efficiency in separating water and lubricating oil.

[0036] When the utility model is working: first, the lubricating oil containing water is injected into the inner cavity of the water filter box 205 through the oil inlet pipe 4, and then the heating wire 8 starts to heat and increases the temperature in the inner cavity of the box body 1. At this time, the temperature of the lubricating oil in the inner cavity of the water filter box 205 is synchronously increased, and then the output end of the servo motor 201 drives the active bevel gear 202 to rotate. As the active bevel gear 202 rotates, the bevel gear ring 203 and the driven bevel gear 206 start to rotate. As the bevel gear ring 203 rotates, the mounting tube 204 and the water filter box 205 rotate, and the driven bevel gear 206 rotates. At the same time, the connecting shaft 207 and the stirring rod 208 also begin to rotate, and since the water filter box 205 and the stirring rod 208 rotate in opposite directions, the lubricating oil in the inner cavity of the water filter box 205 can flow quickly, thereby accelerating the overall temperature rise rate of the lubricating oil, and due to the difference in boiling points between the lubricating oil and water, the water in the lubricating oil begins to evaporate first, and is filtered through the hydrophilic and oleophobic membrane 212, so that the vaporized water enters the inner cavity of the box 1 from the inner cavity of the water filter box 205, and is converted into water again through natural cooling, and is discharged from the inner cavity of the box 1 through the drain port 13, thereby completing the dehydration and purification of the lubricating oil.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
