Description

Technical Field

[0002] Lubricating oil is mainly refined and fractionated from base oil types such as mineral oil, synthetic oil, and vegetable oil, as well as various additives; however, there are a large number of impurities and harmful substances in crude oil, such as sand grains, moisture, heavy metals, sulfides, chlorides, etc., which will gradually be separated and concentrated into slag during the processing of the oil product; these slags must be separated, and an oil residue separation device is required for this purpose.

[0003] The Chinese patent discloses a lubricating oil blending kettle capable of filtering oil residue (authorization publication number CN218688704U). Through the combined use of a stirring motor, a connecting column, a connecting rod, a cleaning plate, and a cleaning pad, this patented technology avoids lumps from adhering to the inner wall of the working chamber during the blending process, which affects the working efficiency and quality, and improves the production efficiency. Through the action of the first filter screen, oil residue is prevented from entering the feed pipe for the first filtration. The oil residue is secondarily filtered by a coarse filter plate and thirdly filtered by a fine filter plate to separate the oil residue from the lubricating oil and prevent the oil residue from entering the collection device together with the lubricating oil, improving the production quality. However, it requires filtering the oil, and the operation is cumbersome with low oil residue separation efficiency. Content of the Utility Model

Specific implementation manners

[0021] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, an oil residue separation device for lubricating oil production includes a separation tank 1 and a filter tank 2 located on one side of the separation tank 1. A slag scraping and conveying mechanism 4 is installed obliquely upward inside the separation tank 1, and an air flotation stirring mechanism 3 is installed at the lower end inside the separation tank 1. A mechanical stirring mechanism 6 is installed between the slag scraping and conveying mechanism 4 and the air flotation stirring mechanism 3 inside the separation tank 1. A filter basket 5 is installed inside the filter tank 2. The slag fished by the slag scraping and conveying mechanism 4 can automatically fall into the filter basket 5. After being filtered by the filter basket 5, a small amount of lubricating oil contained in the slag can fall into the filter tank 2, thereby reducing the phenomenon of lubricating oil waste;

[0022] In Figure 2 and Figure 3Among them, the air flotation stirring mechanism 3 includes a circulation pump 31 and an air compressor 32 installed outside the separation tank 1. The input end of the circulation pump 31 is connected with a water inlet pipe 39, and the output end of the circulation pump 31 is connected with a water outlet pipe 30. The output end of the air compressor 32 is connected with an air pipe 33. One end of the water outlet pipe 30 and the air pipe 33 are jointly connected with a jet injector 34. One end of the jet injector 34 is connected with a main pipe 35. A number of branch pipes 37 are fixedly connected to the main pipe 35, and a number of bubble plates 36 are installed on the branch pipes 37. One end of the water inlet pipe 39 is connected with a filter cylinder 38. Both the filter cylinder 38 and the bubble plates 36 are located at the lower end inside the separation tank 1. The lubricating oil in the separation tank 1 can be filtered through the filter cylinder 38, so as to prevent the dregs in the lubricating oil from being sucked into the water inlet pipe 39 and causing blockage. After the lubricating oil in the separation tank 1 passes through the filter cylinder 38 and the water inlet pipe 39 in sequence by the circulation pump 31, it is pumped into the water outlet pipe 30. At the same time, the air compressor 32 compresses the air and sends it into the air pipe 33. The lubricating oil in the water outlet pipe 30 and the compressed air in the air pipe 33 are violently mixed in the jet injector 34 to form a gas-liquid mixture, and enter the main pipe 35 and the branch pipes 37 in sequence under a certain pressure, and then are sprayed out in the form of bubbles from the bubble plates 36, so as to stir the lubricating oil in the separation tank 1, making the dregs precipitated in the lubricating oil float, so that they can be fished up by the slag scraping and conveying mechanism 4.

[0023] In Figure 2 and Figure 4 Among them, the mechanical stirring mechanism 6 includes a support plate 62 fixedly installed on the inner side wall of the separation tank 1. A second motor 61 is installed at the upper end of the support plate 62. The output end of the second motor 61 is fixedly connected with a stirring shaft 63. A number of stirring blades 64 are installed on the stirring shaft 63. The second motor 61 makes the stirring shaft 63 and the stirring blades 64 rotate, and the stirring blades 64 stir the lubricating oil in the separation tank 1, making the dregs sinking in the lubricating oil float, so that they can be fished up by the slag scraping and conveying mechanism 4.

[0024] In Figure 5 and Figure 6In it, the slag scraping and conveying mechanism 4 includes a conveying frame 41 inclined upward. Inside the conveying frame 41, a sprocket chain assembly 45 is installed. Inside the sprocket chain assembly 45, a chain plate 44 is installed. And at one end of the sprocket chain assembly 45, a first motor 42 is installed through the front side of the conveying frame 41. On the front and rear sides of the upper end of the sprocket chain assembly 45, several groups of fixing blocks 46 are installed respectively. Between each group of fixing blocks 46, a scraper 43 is arranged. On the front and rear sides of the lower end of each scraper 43, an ear 47 is fixedly connected respectively. Each ear 47 and the corresponding fixing block 46 are fixedly connected by screws. After loosening the screws, the ear 47 can rotate along the fixing block 46, so as to adjust the angle between the scraper 43 and the chain plate 44, so as to better fish out the slag from the lubricating oil in the separation tank 1. The first motor 42 is fixedly installed at the front end of the separation tank 1. The upper end of the conveying frame 41 is fixedly installed between the upper ends of the separation tank 1 and the filtration tank 2. The lower end of the chain plate 44 is located in the separation tank 1, and the upper end of the chain plate 44 is located above the filter basket 5, so that the slag fished out from the separation tank 1 can be conveyed into the filter basket 5; The first motor 42 drives the sprocket chain assembly 45 to rotate clockwise. The sprocket chain assembly 45 drives the chain plate 44 and the scraper 43 to rotate clockwise together. When the corresponding scraper 43 enters the lower side of the conveying frame 41, the slag floating on the lubricating oil can be scraped up; When the scraper 43 rotates to the upper side of the conveying frame 41, the scraped-up slag falls onto the corresponding chain plate 44. When the chain plate 44 rotates to the top of the conveying frame 41, it automatically falls into the filter basket 5, so as to achieve the purpose of separating oil and slag.

[0025] The working principle of the present utility model: First, the lubricating oil that needs to separate oil and slag is injected into the separation tank 1;

[0026] Then, the circulation pump 31 is started. The circulation pump 31 pumps the lubricating oil in the separation tank 1 into the water outlet pipe 30 after passing through the filter cylinder 38 and the water inlet pipe 39 in sequence; At the same time, the air compressor 32 is started. The air compressor 32 compresses the air and sends it into the air pipe 33; The lubricating oil in the water outlet pipe 30 and the compressed air in the air pipe 33 are violently mixed in the ejector 34 to form a gas-liquid mixture, and enter the main pipe 35 and the branch pipe 37 in sequence under a certain pressure, and then are ejected from the bubble disk 36 in the form of bubbles, so as to stir the lubricating oil in the separation tank 1, so that the slag precipitated in the lubricating oil floats up;

[0027] Then, the second motor 61 is started. The second motor 61 makes the stirring shaft 63 and the stirring blades 64 rotate. The stirring blades 64 stir the lubricating oil in the separation tank 1, so that the slag sinking in the lubricating oil floats up;

[0028] Next, start the first motor 42. The first motor 42 drives the sprocket chain assembly 45 to rotate clockwise. The sprocket chain assembly 45 drives the chain plate 44 and the scraper 43 to rotate clockwise together. When the corresponding scraper 43 enters the lower side of the conveying frame 41, the slag floating on the lubricating oil is scraped up. When the scraper 43 continues to rotate to the upper side of the conveying frame 41, the scraped slag falls onto the corresponding chain plate 44. When the chain plate 44 rotates to the top of the conveying frame 41, it automatically falls into the filter basket 5, thus achieving the purpose of separating oil and slag.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
