Description

Technical Field

[0001] This utility model relates to the field of crude oil processing technology, and in particular to an automatic crude oil component separation device. Background Technology

[0002] Unprocessed petroleum is conventionally referred to as crude oil. It is a viscous, oily liquid, dark brown with a greenish fluorescence and a distinctive odor, composed of a mixture of various liquid hydrocarbons, including alkanes, cycloalkanes, aromatics, and alkenes. Refining crude oil yields various fuel oils, solvent oils, lubricating oils, greases, paraffin wax, asphalt, liquefied petroleum gas (LPG), and aromatics, providing fuel, raw materials, and chemical products to various sectors of the national economy. The problem with crude oil is that it contains hundreds of different types of hydrocarbons, all mixed together, requiring the separation of different hydrocarbon types to extract the useful substances.

[0003] A search revealed a patent with publication number CN217323970U entitled "A Petroleum Distillation Apparatus for Petroleum Refining." The patent addresses the technical problem that a fan can only blow air in one direction, resulting in a limited cooling range and slow steam liquefaction rate, thus affecting the petroleum refining rate. By coordinating the stirring and cooling components, the petroleum is heated evenly and liquefied rapidly, avoiding the limitation of a fixed fan cooling only in one direction and thus solving the problem of limited cooling range affecting steam liquefaction rate. However, the following drawbacks still need to be addressed: uneven distillation and uneven heating of different petroleum layers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic crude oil component separation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic crude oil component separation device includes a tank. A feed inlet is fixedly connected to the lower end of the tank's circumference. A heating sleeve is fixedly fitted to the bottom end of the tank's circumference. A separation chamber is provided inside the tank. A steam outlet pipe is fixedly installed at an angle at the top of the tank. A bracket is fixedly installed in the middle of the outer wall of the top of the tank. A drive motor is fixedly installed in the middle of the top of the bracket. A rotating shaft is fixedly installed at the output end of the drive motor. A first fixing ring is fixedly installed at the bottom end of the rotating shaft's circumference. A second fixing ring is fixedly installed at the lower end of the rotating shaft's circumference. Three scrapers at equal angles are fixedly installed around the first fixing ring. A reinforcing rod is fixedly installed at an angle between the upper ends of the second fixing ring and the three scrapers.

[0007] Preferably, a heat-insulating base plate is fixedly installed at the bottom end of the heating jacket.

[0008] Preferably, the steam outlet pipe is located inside the separation chamber, and a condensation component is fixedly installed at the end of the steam outlet pipe.

[0009] Preferably, the scraper is composed of a vertical section, a horizontal section and an inclined section, with the vertical section of the scraper fitting against the inner circumference of the separation cavity, the horizontal section of the scraper fitting against the outer side of the bottom inner wall of the separation cavity, and the inclined section of the scraper having multiple equally spaced layered plates fixedly installed.

[0010] Preferably, the lengths of the multiple layered plates increase sequentially from bottom to top, the ends of the multiple layered plates are all located on the same horizontal plane, and the three groups of layered plates are distributed at equal angles with the middle of the inner wall at the bottom of the separation cavity as the center.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model proposes an automatic crude oil component separation device. Crude oil is introduced into the separation chamber of the tank through the feed inlet. The crude oil inside the tank is heated by a heating jacket, and the heating temperature is controlled. When the temperature inside the separation chamber reaches the boiling point of a certain component in the crude oil, the component evaporates from the crude oil and disperses to the top of the separation chamber. Its vapor is introduced into the condensation component through the vapor outlet pipe and converted into liquid for outlet, thereby separating the component from the crude oil. During this process, the drive motor works to rotate the shaft, which in turn causes three scrapers, reinforcing rods, and stratification plates to rotate. The scrapers are composed of vertical, horizontal, and inclined sections. During the rotation of the scrapers, they not only drive the reinforcing rods to stir the crude oil, but also scrape off the crude oil adhering to the inner wall of the separation chamber and other locally heated components by the three-component stratification plates scraping and mixing the crude oil at the bottom. This ensures the uniformity of distillation and the uniform heating of the crude oil. The length of the multiple stratification plates increases from bottom to top, and the ends of the multiple stratification plates are all located on the same horizontal plane, further enhancing the mixing effect of the crude oil during the heating process and ensuring uniform heating of the crude oil.

[0013] 2. The present invention proposes an automatic crude oil component separation device, wherein a reinforcing rod is obliquely fixed between the circumference of the second fixing ring and the upper end of the three scrapers. The reinforcing rod not only connects the second fixing ring and the scrapers to enhance the stability of the scrapers during the rotation of the shaft, but also stirs and mixes the crude oil, which helps to heat the crude oil evenly and increase the distillation speed.

[0018] Reference Figure 1-3 An automatic crude oil component separation device includes a tank 1, a feed inlet 2 fixedly connected to the lower circumference of the tank 1, a heating sleeve 3 fixedly sleeved at the bottom circumference of the tank 1, a separation chamber 5 provided inside the tank 1, a steam outlet pipe 6 fixedly installed at the top of the tank 1 at an angle, a bracket 7 fixedly installed in the middle of the outer wall of the top of the tank 1, and a drive motor 8 fixedly installed in the middle of the top of the bracket 7, a rotating shaft 9 fixedly installed at the output end of the drive motor 8, a first fixing ring 10 fixedly installed at the bottom circumference of the rotating shaft 9, a second fixing ring 12 fixedly installed at the lower circumference of the rotating shaft 9, three scrapers 11 at equal angles fixedly installed around the first fixing ring 10, and a reinforcing rod 13 fixedly installed at an angle between the upper ends of the second fixing ring 12 and the three scrapers 11.

[0019] In this utility model, a heat insulation base plate 4 is fixedly installed at the bottom end of the heating jacket 3;

[0020] The steam outlet pipe 6 is located inside the separation chamber 5, and a condenser assembly is fixedly installed at the end of the steam outlet pipe 6.

[0021] The scraper 11 consists of a vertical section, a horizontal section and an inclined section. The vertical section of the scraper 11 is attached to the inner circumference of the separation cavity 5, the horizontal section of the scraper 11 is attached to the outer side of the bottom inner wall of the separation cavity 5, and multiple equally spaced layered plates 14 are fixedly installed on the inclined section of the scraper 11.

[0022] The length of the multiple layered plates 14 increases sequentially from bottom to top, and the ends of the multiple layered plates 14 are all located on the same horizontal plane. The three groups of layered plates 14 are distributed at equal angles with the middle of the inner wall of the bottom of the separation cavity 5 as the center.

[0023] Working principle: Crude oil is introduced into the separation chamber 5 of tank 1 through inlet 2. Heating jacket 3 heats the crude oil inside tank 1 and controls the heating temperature. When the temperature inside separation chamber 5 reaches the boiling point of a certain component in the crude oil, this component evaporates from the crude oil and disperses to the top of the separation chamber 5. Its vapor is introduced into the condensation assembly through vapor outlet pipe 6 and converted into liquid for outlet, thus separating the component from the crude oil. During this process, drive motor 8 operates to rotate shaft 9, which in turn causes the three scraper bars 11, reinforcing rod 13, and stratification plate 14 to rotate accordingly. The rod 11 consists of a vertical section, a horizontal section, and an inclined section. During rotation, the scraper 11 can not only drive the reinforcing rod 13 to stir the crude oil, but also scrape off the crude oil adhering to the inner wall of the separation chamber 5 and other locally heated components, thereby ensuring the uniformity of distillation and the uniform heating of the crude oil. In addition, the length of the multiple layered plates 14 increases from bottom to top, and the ends of the multiple layered plates 14 are all located on the same horizontal plane, which further enhances the mixing effect of the crude oil during the heating process and ensures that the crude oil is heated evenly.

[0024] A reinforcing rod 13 is obliquely fixed between the circumference of the second fixing ring 12 and the upper end of the three scrapers 11. The reinforcing rod 13 not only connects the second fixing ring 12 and the scrapers 11 to enhance the stability of the scrapers 11 as they rotate with the shaft 9, but also stirs and mixes the crude oil, which helps to heat the crude oil evenly and increase the distillation speed.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
