[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] A lubricating oil base oil dewaxing cooling mechanism, combined with Figure 1 to Figure 2 As shown, it includes a box body 1, and two horizontally arranged partitions are arranged from bottom to top inside the box body 1. The partitions divide the inside of the box body 1 into an air inlet cavity 2, a cooling cavity 3 and an air outlet cavity 4 from bottom to top.

[0020] The top side wall of the box body 1 is provided with a feed port 17, which is connected to the cooling chamber 3 and is used to feed lubricating base oil and additives into the cooling chamber 3. The feed port 17 is provided with a valve, which is used to open and close the feed port 17.

[0021] A motor 9 is arranged on the top of the box body 1, and the rotating shaft of the motor 9 is arranged vertically downward and penetrates into the air outlet cavity 4 to be connected with a rotating shaft 10, the rotating shaft 10 is arranged longitudinally and rotatably arranged in the cooling cavity 3, and a plurality of stirring blades 11 are evenly arranged on the rotating shaft 10. The stirring blades 11 stir the lubricating oil base oil and the additive under the drive of the motor 9, so as to ensure the mixing effect of the lubricating oil base oil and the additive.

[0022] An air inlet 13 is provided at the bottom of the side wall of the box body 1, and the air inlet 13 is connected to the air inlet cavity 2. The air inlet 13 is connected to the air cooler 14 through a pipeline, and is specifically connected to the cold air outlet of the air cooler 14, thereby realizing the connection between the air inlet cavity 2 and the air cooler 14. The air cooler 14 is used to introduce cold air into the air inlet cavity 2.

[0023] A plurality of heat exchange tubes 5 are vertically arranged inside the cooling chamber 3, the bottom end of the heat exchange tube 5 is connected to the air inlet chamber 2, and the top end of the heat exchange tube 5 is connected to the air outlet chamber 4. When the air cooler 14 introduces cold air into the air inlet chamber 2, the cold air enters each heat exchange tube 5 and exchanges heat with the lubricating oil base oil in the cooling chamber 3, lowering the temperature of the lubricating oil base oil, thereby achieving crystallization of wax from the lubricating oil base oil. At the same time, the motor 9 continues to drive the stirring blade 11 to stir, achieving uniform heat exchange, which is conducive to the crystallized wax to form larger particles, which is convenient for subsequent separation mechanism to separate; the gas after heat exchange enters the air outlet chamber 4.

[0024] An air outlet 15 is provided on the upper part of the side wall of the box body 1 . The air outlet 15 is communicated with the air outlet cavity 4 . The heat-exchanged gas flowing into the air outlet cavity 4 is discharged from the air outlet cavity 4 through the air outlet 15 .

[0025] The bottom of the box body 1 is provided with a discharge port 16, which is connected to the cooling chamber 3 and is used to discharge the lubricating base oil and the crystallized wax in the cooling chamber 3, so as to facilitate the subsequent entry into the separation mechanism; a valve is provided on the discharge port 16, and the valve is used to control the opening and closing of the discharge port 16. Support legs 18 are provided at the four corners of the bottom of the box body 1, and the support legs 18 are used to support the box body 1.

[0026] A horizontally arranged ring plate 6 is slidably mounted on a plurality of heat exchange tubes 5. A scraper 7 is arranged on the lower surface of the ring plate 6. The scraper 7 is arranged one-to-one with the heat exchange tube 5. The scraper 7 is an inverted cone structure and wraps the heat exchange tube 5 inside. The stirring blade 11 avoids the ring plate 6 and the scraper 7. An electric cylinder 8 is connected to the upper surface of the ring plate 6. The electric cylinder 8 is arranged on the top of the box body 1. Specifically, the telescopic rod of the electric cylinder 8 penetrates the cooling chamber 3 and is fixedly connected to the upper surface of the ring plate 6. The electric cylinder 8 is used to drive the ring plate 6 to move downward, thereby driving the scraper 7 to move downward, so that the scraper 7 can scrape off the wax attached to the heat exchange tube 5, and then the wax attached to the heat exchange tube 5 can be removed in time, which is beneficial to improving the heat exchange efficiency and greatly improving the dewaxing efficiency. After scraping off the wax attached to the heat exchange tube 5, the electric cylinder 8 drives the ring plate 6 to drive the scraper 7 to rise and reset.

[0027] An electric heater 12 is provided inside the side wall of the housing 1, and the electric heater 12 is used to heat the housing 1. After the lubricating base oil and the crystallized wax in the cooling chamber 3 are discharged, the discharge port 16 is closed, and the electric heater 12 is started. The electric heater 12 heats the housing 1 to increase the temperature of the cooling chamber 3. After the temperature of the cooling chamber 3 is increased, the wax attached to the cooling chamber 3 and the heat exchange tube 5 melts, and the wax liquid is discharged through the discharge port 16, thereby cleaning the wax in the cooling chamber 3.

[0028] When the utility model is in use, the lubricating oil base oil and the additive are put into the cooling chamber 3 through the feed port 17, and the motor 9 is started to stir the lubricating oil base oil and the additive to ensure that they are fully and evenly mixed; the air cooler 14 is started to pass cold air into the air inlet chamber 2, and the cold air exchanges heat with the lubricating oil base oil mixed with the additive through the heat exchange tube 5, thereby reducing the temperature of the lubricating oil base oil and crystallizing the wax in the lubricating oil base oil, and the air cooler 14 can timely provide cold air with a temperature that meets the requirements, thereby shortening the heat exchange time; when more wax is attached to the heat exchange tube 5, the electric cylinder 8 is started to drive the ring plate 6 to drive the scraper 7 to move downward, such as Figure 2 As shown, the wax on the heat exchange tube 5 is scraped off, and then the electric cylinder 8 drives the ring plate 6 to drive the scraper 7 to move upward and reset; when the cooling work is completed, the lubricating oil base oil and the crystallized wax in the cooling chamber 3 are discharged through the discharge port 16; when the internal wax of the cooling chamber 3 needs to be cleaned, the electric heating body 12 is turned on to heat the box body 1 to increase the temperature of the cooling chamber 3, thereby melting the wax in the cooling chamber 3, and then the discharge port 16 is opened to discharge the wax liquid.
