Description

Technical Field

[0001] The utility model relates to the technical field of crude oil recovery, in particular to a crude oil recovery device for exploiting offshore oil. Background Art

[0002] Crude oil is not only a natural resource, it also plays an important role in global energy supply, economic development and environmental protection. Crude oil is the raw material for many chemical products and can be used to produce lubricants, greases, paraffin, asphalt, liquefied gas, aromatics and other products. These chemical products play an important role in various sectors of the national economy.

[0003] After searching, the Chinese patent authorization announcement number CN 214058666 U discloses a crude oil recovery device for exploiting offshore oil, including a storage mechanism, a cleaning and stirring mechanism, a motor and a drive shaft. The storage mechanism can store the crude oil intact therein, and play a supporting and protective role for the entire device. The cleaning mechanism removes the crude oil residues deposited for a long time inside the tank body. The motor can provide power for the cleaning and stirring mechanism, saving manpower for cleaning. The drive shaft can transmit the power generated by the motor to the cleaning and stirring mechanism. The exploited crude oil enters the tank body through the oil inlet. In order to prevent the crude oil from being stationary for a long time, which makes the crude oil precipitation at the bottom of the tank body more viscous, the motor is started regularly to stir the crude oil. When the storage mechanism needs to be cleaned after being used for a certain period of time, the cleaning head at the top of the connecting rod brushes the inner wall of the tank body, and clean water is sprayed from the water outlet onto the inner wall of the tank body, thereby improving the cleaning effect of the cleaning head.

[0004] The existing crude oil needs to be stored in a sealed tank during recovery, waiting for further processing. However, when the crude oil is transported to the storage tank, there are more impurities in the crude oil. After filtering, most of the impurities remain on the filter element, affecting the filtering effect. In addition, during the transportation and processing of crude oil, it will cause wear and tear on equipment such as pumps, pipelines and valves, shortening the service life of the equipment.

[0036] See also Figures 1 to 5 As shown, this embodiment is a crude oil recovery device for exploiting offshore oil, comprising:

[0037] A main body component, the main body component includes a storage tank 11;

[0038] An oil inlet pipe 12 is connected to one side of the outer surface of the storage tank 11, a sealing cover 13 is installed on the upper surface of the storage tank 11, an oil outlet pipe 14 is connected to the lower surface of the storage tank 11, a bottom frame 15 is connected to the lower surface of the storage tank 11, a mounting plate 16 is connected to one side of the outer surface of the bottom frame 15, and a motor 17 is fixed inside the mounting plate 16;

[0039] The oil inlet pipe 12 and the oil outlet pipe 14 are responsible for the input and output of crude oil respectively. The sealing cover 13 is located on the upper surface of the storage tank 11. Its main function is to ensure the sealing of the tank body, prevent crude oil leakage and external impurities from entering, and facilitate the inspection and maintenance of the internal environment.

[0040] The filter assembly includes a mounting groove 21, a fixing ring 22, a filter element 23, a mounting hole 24, and a fixing hole 25;

[0041] The mounting groove 21 is formed on the inner wall of the storage tank 11, the fixing ring 22 is installed inside the mounting groove 21, the filter element 23 is connected to the outer surface of the fixing ring 22, the mounting hole 24 is formed on the lower end of the filter element 23, and the fixing hole 25 is formed on the inner wall of the lower end of the filter element 23;

[0042] The mounting groove 21 is located on the inner wall of the storage tank 11, providing necessary installation space for the filter assembly. The fixing ring 22 is installed inside the mounting groove 21, and is used to fix the filter element 23. The filter element 23 is connected to the outer surface of the fixing ring 22, and is a key component directly involved in the separation of crude oil impurities. Its microporous structure can effectively intercept solid particles and other impurities in the crude oil, ensuring the cleanliness of the crude oil and the smooth progress of the downstream process;

[0043] A collecting frame 26 is installed inside the mounting hole 24, a through hole 27 is opened on one side of the outer surface of the collecting frame 26, a connecting handle 28 is passed through the through hole 27, and a baffle 29 is fixed on one side of the outer surface of the connecting handle 28;

[0044] The collecting frame 26 is installed inside the mounting hole 24 below the filter element 23. Its function is to collect the impurities filtered out from the filter element 23, which facilitates the cleaning of the impurities and avoids the secondary distribution of the impurities inside the storage tank, thus maintaining the cleanliness of the tank and the quality of the crude oil.

[0045] Working principle:

[0046] When the oil inlet pipe 12 delivers crude oil to the storage tank 11;

[0047] First, the crude oil will pass through the filter element 23, and the filter element 23 will filter out impurities in the crude oil;

[0048] And because the filter element 23 is funnel-shaped, impurities will pass through the inclined surface of the filter element 23 and slide into the collection frame 26;

[0049] When there are many impurities in the collecting frame 26, the staff will open the sealing cover 13, then hold the connecting handle 28 and pinch it towards the middle to tighten the lower end of the connecting handle 28;

[0050] The lower end of the connecting handle 28 can be pulled out from the fixing hole 25, and the baffle 29 will block the outside of the through hole 27. The connecting handle 28 is lifted upward, and the collection frame 26 is directly taken out to dump the internal impurities.

[0051] The funnel-shaped design of the filter element 23 allows impurities to slide into the collection frame 26 through the inclined surface;

[0052] This step makes it easier for staff to clean regularly and maintain the effective operation of the filtration system.

[0053] See also Figure 5 to Figure 6 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0054] Clean up components;

[0055] The cleaning assembly includes a rotating shaft 31, a limiting frame 32, a movable frame 33, a cleaning brush 34, a connecting column 35, and a connecting block 36;

[0057] The rotating shaft 31 is directly connected to the output end of the motor 17. This configuration enables the motor 17 to directly transmit power to the rotating shaft 31, thereby driving the entire cleaning assembly to work. This design ensures the efficiency and stability of power transmission and is the basis for achieving an efficient cleaning function.

[0058] The connecting column 35 is fixed on the lower surface of the movable frame 33 and interacts with the connecting block 36, so that the movable frame 33 moves up and down to contact the filter element 23, driving the filter element 23 to vibrate, thereby enhancing the cleaning effect.

[0059] Working principle:

[0060] When crude oil is stored inside the storage tank 11;

[0061] First, the staff starts the motor 17 through the external control module, and the motor 17 drives the rotating shaft 31 to rotate inside the storage tank 11, and the movable frame 33 rotates, which drives the cleaning brush 34 to scrape the inner wall of the storage tank 11;

[0062] The rotating shaft 31 rotates, synchronously driving the limit frame 32 to rotate, and driving the movable frame 33 to rotate, and the movable frame 33 simultaneously drives the connecting column 35 to rotate;

[0063] When the connecting column 35 rotates, it will contact the connecting block 36, and the inclined surface of the connecting block 36 will push the connecting column 35 to move up and down;

[0064] Under the fixation of the limit frame 32, the movable frame 33 will move up and down, and the movable frame 33 will contact the filter element 23 upward, driving the filter element 23 to vibrate, further accelerating the impurities to fall into the collection frame 26;

[0065] In this step, through the action of the rotating shaft 31 driven by the motor 17 and related mechanical components, the impurity filtering and collection process inside the crude oil storage tank 11 is significantly optimized, which not only improves the processing efficiency and quality of the crude oil.
