[0002] Raw material pretreatment units in lubricant production are primarily used to ensure that base oils and additives reach the required purity and physicochemical properties before entering the final blending stage. These units effectively remove impurities, moisture, and gases, and perform necessary modification treatments on the base oils to improve their performance.

[0003] Patent CN214635557U discloses a lubricating oil raw material pretreatment device, including a shell, a base, and a pretreatment mechanism. The shell is located above the base, and the pretreatment mechanism is located inside the shell. One end of the pretreatment mechanism penetrates the shell and is fixedly connected to a discharge pipe. A discharge port connected to the shell is opened on one side of the base. The pretreatment mechanism includes a conveying component and a scraping component connected to the outside. The conveying component is located on one side of the shell, and the scraping component is located on the inner wall of the shell. While the above patent, by setting up a conveying component, can mix the raw materials during the conveying process, ensuring thorough mixing for subsequent use, and can also filter and discharge impurities from the raw materials for easier use, in actual use, lubricating oil raw materials contain a large number of impurities, including larger particles, fine particles, organic chemicals, and pigments. These impurities cannot be effectively removed during the raw material conveying process, which may adversely affect subsequent production and use, reducing the purity and quality of the oil.

[0004] Therefore, a raw material pretreatment device for lubricant production with fine filtration function is needed. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example 1: A raw material pretreatment device for lubricating oil production, please refer to [link / reference]. Figures 1-5The device includes a pretreatment tank 1, a shielding cover 2, a first discharge pipe 3, a first valve 4, a high-pressure water pump 5, a connecting pipe 6, a handle 7, and a dewatering mechanism. The shielding cover 2 is threaded onto the top of the pretreatment tank 1. The first discharge pipe 3 is connected to and communicates with the bottom of the pretreatment tank 1. The first valve 4 is installed on the first discharge pipe 3. The high-pressure water pump 5 is installed on the pretreatment tank 1. The outlet end of the high-pressure water pump 5 is connected to and communicates with the connecting pipe 6. One end of the connecting pipe 6 is snapped into the shielding cover 2. The handle 7 is fixedly connected to the top of the shielding cover 2. One end of the first discharge pipe 3 is connected to the dewatering mechanism. The dehydration mechanism is used to remove water from the base oil. It includes a protective frame 12, a dehydration tank 121, a protective cover 13, a second discharge pipe 14, a second valve 15, a heating pipe 16, a control unit 17, and a safety valve 18. One end of the first discharge pipe 14 is connected to the dehydration tank 121. A protective frame 12 is installed on the outside of the dehydration tank 121, and the protective cover 13 covers the tank. The bottom of the dehydration tank 121 is connected to and communicates with the second discharge pipe 14, which is equipped with a second valve 15. The protective frame 12 and the dehydration tank 121 are connected... A heating element 16 is installed between the pretreatment tank 1 and the dehydration tank 121. The heating element 16 is wound around the dehydration tank 121. A control unit 17 is installed on the protective frame 12 and is electrically connected to the heating element 16. Two safety valves 18 are installed on the protective cover 13. During heating, when the air pressure inside the dehydration tank 121 reaches a certain value, the safety valves 18 will be lifted to release the air, thereby preventing an explosion due to excessive air pressure. An activated carbon layer 8 is installed inside the pretreatment tank 1. A ceramic filter element 9 is installed above the activated carbon layer 8, and a glass fiber filter element 1 is installed above the ceramic filter element 9. 0. The shielding cover 2 has a non-woven fabric layer 11 inside. A prompting plate 22 is fixedly connected to the second valve 15. When the second valve 15 is rotated, the prompting plate 22 also rotates. By checking the direction on the prompting plate 22, it is easy to understand the opening and closing status of the second valve 15. A rotating ring 23 is fixedly connected to the outside of the shielding cover 2, so as to facilitate the rotation of the shielding cover 2 and open the pretreatment tank 1. A protective shell 24 is installed on the pretreatment tank 1. The high-pressure water pump 5 is located inside the protective shell 24, thereby protecting the protective shell 24 and preventing the high-pressure water pump 5 from being interfered with by the outside.

[0022] When pretreatment of lubricating oil raw materials is required, firstly, connect the external pipeline to the inlet of the high-pressure water pump 5. After ensuring a secure connection, start the high-pressure water pump 5. Once the high-pressure water pump 5 is running, it draws the base oil into the connecting pipe 6, and then through the connecting pipe 6 into the non-woven fabric layer 11 for initial filtration to remove larger particles. After initial filtration, the base oil enters the glass fiber filter element 10 for secondary filtration to remove metal substances and dust. After secondary filtration, the base oil enters the ceramic filter element 9 for final filtration, effectively removing fine particles and microorganisms to ensure the lubricating oil reaches extremely high purity. After filtration, the base oil continues to flow downwards, passing through the activated carbon layer 8, where it is further filtered. The carbon layer 8 adsorbs organic compounds, pigments, odors, and some chemical contaminants in the oil. Through the above steps, the base oil is finely filtered, effectively removing various impurities, pigments, and odors from the base oil, thereby avoiding adverse effects on subsequent production and use, and improving the quality and purity of the oil. During this process, the first valve 4 is turned to open the pretreatment tank 1, allowing the treated oil to enter the dehydration tank 121 through the first discharge pipe 3. When there is an appropriate amount of oil in the dehydration tank 121, the heating tube 16 is activated by the control unit 17, and the heating temperature is controlled. The heating tube 16 heats the oil to remove water from the base oil, preventing water from reducing the performance of the lubricating oil.

[0023] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 5 A support frame 19 is fixedly connected to the protective cover 13, a motor 20 is installed on the support frame 19, and a stirring rod 21 is connected to the output shaft of the motor 20.

[0024] During the heating process, once a certain temperature condition is reached, the motor 20 is started. The output shaft of the motor 20 rotates, driving the stirring rod 21 to rotate. This causes the stirring rod 21 to stir the base oil inside the dehydration tank 121, ensuring that the base oil is heated evenly. This shortens the water evaporation time and improves the pretreatment efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
