Description

Technical Field

[0001] This utility model relates to a recycling device, specifically an automatic vacuum oil recycling device, belonging to the field of vacuum oil recycling technology. Background Technology

[0002] Vacuum oil plays a crucial role in the operation of vacuum equipment. It not only provides excellent lubrication, reducing friction and wear between internal components and ensuring smooth operation and extending the equipment's lifespan, but also enhances the equipment's sealing performance by forming an oil film inside, preventing external air intrusion and maintaining a stable vacuum environment. This ensures the vacuum equipment can effectively perform its core functions, such as vacuuming. However, after a period of use, the vacuum oil in vacuum equipment gradually deteriorates into waste vacuum oil. This waste oil contains a large amount of impurities, such as metal shavings and dust generated during equipment operation, and also absorbs a certain amount of moisture, leading to a significant decline in its performance and rendering it unable to meet the requirements of vacuum equipment. Due to the current lack of effective recycling methods, this waste vacuum oil is generally discarded directly. This not only causes serious resource waste and increases production costs for enterprises, but also may cause environmental pollution if discarded carelessly. Therefore, an automatic vacuum oil recovery device is proposed. Utility Model Content

Detailed Implementation

[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-5 As shown, this utility model embodiment provides an automatic vacuum oil recovery device, including a support frame 31, and a main component 101 is arranged inside the support frame 31. The main component 101 includes a filter 11, an oil storage tank 12, an oil delivery pipe 14, a recovery bucket 15, a drive motor 16, a filter box 17, a vacuum pump 18, a stirring rod 20, a heat-conducting ring 21, a heating wire 22, and a heat insulation cover 23. A connecting pipe 27 is installed at the inlet end of the filter 11. The connecting pipe 27 is used to connect the oil suction hose. One end of the oil suction hose is connected to the oil chamber inside the vacuum equipment. The outlet of filter 11 is connected to the inlet of oil storage tank 12 through a pipe. The outlet of oil storage tank 12 is connected to the inlet of filter box 17 through a pipe. The outlet of filter box 17 is connected to the air inlet of vacuum pump 18 through a pipe. When vacuum pump 18 is started, negative pressure is formed inside filter box 17, oil storage tank 12 and filter 11. At this time, connecting pipe 27 starts to draw vacuum oil from the vacuum equipment. Vacuum oil first enters filter 11. After filter 11 filters out impurities such as metal scraps and dust, it flows into oil storage tank 12. The heat-conducting ring 21 is fixedly connected to the outer wall of the oil storage tank 12. The heating wire 22 is embedded in the outer wall of the heat-conducting ring 21. The heat insulation cover 23 is installed on the outer wall of the oil storage tank 12 and is located outside the heat-conducting ring 21 and the heating wire 22. When the heating wire 22 is working, the heating wire 22 transfers heat to the oil storage tank 12 through the heat-conducting ring 21. The temperature inside the oil storage tank 12 increases, causing the water vapor in the vacuum oil to vaporize, thereby ensuring the purity and performance of the vacuum oil, such as viscosity and oxidation resistance. The filter box 17 has a sliding connection to a storage compartment 25, and a filter element 24 is installed inside the storage compartment 25. After the water vapor in the vacuum oil vaporizes, the gas containing moisture enters the filter box 17 under the action of the vacuum pump 18 and then comes into contact with the filter element 24. The filter element 24 uses silica gel desiccant, which can effectively absorb moisture, thereby ensuring the stable operation of the vacuum pump 18. The storage compartment 25 has a hollow design to ensure airflow and facilitates the removal of the filter element 24. The oil storage tank 12 is connected to the recovery tank 15 through the oil pipeline 14. The recovery tank 15 is used to store the purified vacuum oil. The drive motor 16 is installed on the top of the oil storage tank 12, and the output shaft of the drive motor 16 is fixedly connected to the top of the stirring rod 20. The stirring rod 20 is located inside the oil storage tank 12. The output shaft of the drive motor 16 is rotatably connected to the oil storage tank 12 through a sealed bearing. When the oil storage tank 12 heats the vacuum oil inside, the drive motor 16 drives the stirring rod 20 to rotate. The stirring rod 20 stirs the vacuum oil in the oil storage tank 12, thereby ensuring that the vacuum oil is heated evenly and thus accelerating the process of water vaporization.

[0020] In one embodiment, an oil drain pipe 28 is installed on one side of the bottom of the recycling tank 15. Both the oil drain pipe 28 and the oil supply pipe 14 are equipped with control valves 26, through which the vacuum oil in the recycling tank 15 can be discharged.

[0021] In this utility model, a PLC controller (not shown in the figure) is provided on the support frame 31. The signal terminals of the PLC controller are respectively connected to the signal terminals of the drive motor 16, the heating wire 22 and the vacuum pump 18, so as to control the working status of the drive motor 16, the heating wire 22 and the vacuum pump 18. The heating temperature of the heating wire 22 is set at 65-70℃; During operation, a vacuum pressure reducing valve can be added to the oil storage tank 12 to reduce the pressure and lower the boiling point of water, such as boiling point ≈ 45℃ at -0.08MPa. An online viscometer (not shown in the figure) is installed on the oil pipeline 14 to detect the quality of the vacuum oil, such as its viscosity.

[0022] In one embodiment, two mounting plates 32 are fixedly connected inside the support frame 31. The filter 11, oil storage tank 12, filter box 17 and vacuum pump 18 are all mounted on the upper mounting plate 32, and the recycling tank 15 is mounted on the lower mounting plate 32. Thus, the stability of the overall structure can be enhanced by the support frame 31 and the mounting plates 32.

[0023] When this utility model is in operation: the connecting pipe 27 is connected to the oil suction hose, and one end of the oil suction hose is connected to the oil chamber inside the vacuum equipment. Then, the vacuum pump 18 and the heating wire 22 are started. At this time, the filter box 17, the oil storage tank 12 and the filter 11 are all in a negative pressure state. The connecting pipe 27 starts to suck the vacuum oil in the vacuum equipment. The vacuum oil first enters the filter 11. After the filter 11 filters out impurities such as metal fragments and dust, it flows into the oil storage tank 12. At the same time, the heating wire 22 transfers heat to the oil storage tank 12 through the heat conduction ring 21. The temperature inside the oil storage tank 12 increases, causing the water vapor in the vacuum oil to vaporize. Then, the drive motor 16 drives the stirring rod 20 to rotate. The stirring rod 20 stirs the vacuum oil in the oil storage tank 12, thereby ensuring that the vacuum oil is heated evenly and accelerating the process of water vaporization. By opening the control valve 26 on the oil delivery pipe 14, the vacuum oil flows into the recovery tank 15, and the recovery of vacuum oil is completed. This invention achieves the recovery of vacuum oil through the combination of a filter 11, a vacuum pump 18, an oil storage tank 12, and a heating wire 22. During the recovery process, impurities in the vacuum oil can be removed, and water in the vacuum oil can be discharged, ensuring the purity and performance of the vacuum oil. Moreover, under the stirring of the stirring rod 20, the vacuum oil can be heated evenly, thereby accelerating the process of water vaporization.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
