Description

Technical Field

[0001] This utility model relates to the field of oil storage device technology, specifically an oil storage device for oilfield production. Background Technology

[0002] The main function of oilfield storage facilities is to store crude oil extracted from oil wells for subsequent processing and transportation. These facilities need to meet the requirements of various environmental and operating conditions, such as high temperature resistance, corrosion resistance, and good sealing performance, to ensure the quality and safety of the crude oil during storage.

[0003] Furthermore, with continuous technological advancements, oilfield storage devices are constantly being improved and innovated to enhance their performance and efficiency. For instance, modern storage devices may employ more advanced materials, feature more rationally designed structures, and be equipped with more intelligent monitoring and management systems to adapt to more complex oilfield environments and higher production requirements.

[0004] In the prior art, an oil storage device for oilfield production, disclosed in publication number "CN217919277U", includes a base plate and an oil storage tank. A top cover is provided at the upper end of the oil storage tank. An oil inlet and a pull handle are fixedly connected to the upper surface of the top cover. A sealing ring is fixedly connected to the lower surface of the top cover. A sealing ring groove is formed on the upper surface of the oil storage tank. A first fixing block is fixedly connected to the surface of the top cover, and a second fixing block is fixedly connected to the surface of the oil storage tank. A through hole is formed on the surface of the second fixing block. This invention, through the sealing ring and sealing ring groove, achieves better sealing when the oil storage tank and top cover are connected, thereby reducing the oil evaporation rate. Furthermore, by incorporating an inner wall scraper, a cross-shaped fixing bracket, a fixing rod, and a pull ring, the inner wall of the oil storage tank can be easily cleaned after use, preventing contamination during subsequent use.

[0005] However, existing technologies still have significant shortcomings, such as:

[0006] Existing oil storage devices often lack effective stirring and scraping mechanisms, which makes it easy for sediments in the oil to accumulate in the storage tank, affecting the quality of the oil and the cleanliness of the storage tank. At the same time, existing oil storage devices often lack effective temperature control methods, and the quality of the oil can easily decrease due to temperature rise during storage, or even cause safety accidents. Utility Model Content

[0007] The purpose of this invention is to provide an oil storage device for oilfield production, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An oil storage device for oilfield production includes an oil storage tank body and several bases. The top of the oil storage tank has an oil inlet. An agitator is rotatably mounted in the oil storage tank body. Several connecting rods are fixedly mounted on the agitator. Scrapers arranged in a spiral pattern are fixedly mounted on the connecting rods. The scrapers are in close contact with the inside of the oil storage tank body. When the agitator drives the scrapers to rotate, the scrapers scrape off the sediments attached to the inner wall of the oil storage tank body.

[0010] A drive motor is fixedly installed on the outer side wall of the oil storage tank body. A worm gear is fixedly sleeved on the shaft of the drive motor. One end of the stirring rod passes through the side wall of the oil storage tank body. A worm wheel that meshes with the worm gear is fixedly installed on one end of the stirring rod. The drive motor drives the stirring rod to rotate through the meshing transmission of the worm wheel and the worm gear.

[0011] The outer wall of the oil storage tank body is also equipped with a cooling component for cooling the tank body.

[0012] Preferably, the cooling assembly includes a pump fixedly mounted on the outer wall of the oil storage tank body, the pump shaft being fixedly connected to the shaft of a drive motor, the pump being connected to a cooling pipe filled with coolant, and the cooling pipe being arranged on the outer wall of the oil storage tank body in a spiral wound manner.

[0013] Preferably, a bearing seat is fixedly provided on the side wall of the oil storage tank body, and the bearing seat is used to support the rotating shaft of the drive motor.

[0014] Preferably, a buffer pad is fixedly provided at the connection between the drive motor and the main body of the oil storage tank.

[0015] Preferably, the top of the oil storage tank is provided with several observation holes, and a sealing cover is fixedly installed above the observation holes.

[0019] Preferably, a lifting lug is fixedly installed on the top of the main body of the oil storage tank, and a climbing ladder is fixedly installed on the side wall of the oil storage tank.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The rotation of the stirring rod causes the connecting rod and scraper to form a spiral motion inside the oil storage tank, effectively promoting the mixing and flow of the oil, preventing oil stratification or sedimentation, and improving the uniformity of the oil. The scraper fits tightly against the inner wall of the oil storage tank. As the stirring rod rotates, the scraper can scrape off the sediment on the inner wall, preventing its long-term accumulation and ensuring the cleanliness of the oil storage tank and the purity of the oil. Regular cleaning of the inner wall of the oil storage tank reduces the corrosion and damage of sediment to the tank body, extends the service life of the oil storage tank, and enhances its long-term stability.

[0022] 2. The cooling pipes are tightly fitted to the outer wall of the oil storage tank in a spiral wound manner. The circulating coolant effectively absorbs heat from inside the tank, lowering the oil temperature and ensuring oil quality and the long-term stability of the storage tank. By reducing the oil temperature, the risk of oil evaporation and leakage caused by high temperatures is reduced, improving the safety of the oil storage device.

[0023] 3. The pump and drive motor shafts are fixedly connected through a special design, enabling power sharing, reducing energy consumption, and lowering equipment operating costs.

[0024] During use, when the drive motor starts, its shaft drives the worm gear to rotate, which in turn drives the stirring rod to rotate via the worm wheel. The scraper on the stirring rod closely adheres to the inner wall of the oil storage tank, scraping off sediment and promoting oil mixing. Simultaneously, the pump starts with the motor, circulating coolant through the cooling pipes. The coolant spirals around the outer wall of the oil storage tank, carrying away heat and dissipating it into the air, ensuring the stability and safety of the oil. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 This utility model provides a technical solution:

[0034] Example 1:

[0035] In oilfield production operations, oil storage devices are indispensable and crucial equipment. To improve oil storage efficiency, prevent sediment buildup in the oil, and ensure the long-term stability of oil storage tanks, a new type of oil storage device for oilfield production has been specially designed.

[0036] The core component of this device is the oil storage tank body 1, which is made of high-strength material and can withstand significant pressure and impact. An oil inlet 3 is designed at the top of the oil storage tank for convenient and rapid oil injection. Inside the oil storage tank body 1, a stirring mechanism is installed to ensure the uniformity and fluidity of the oil during storage.

[0037] A stirring rod 4 is rotatably mounted at the center of the oil storage tank body 1. One end of the stirring rod 4 penetrates the side wall of the oil storage tank body 1 and is designed with a sealing feature to ensure that the oil storage tank remains sealed when the stirring rod 4 is rotated.

[0038] Several connecting rods 5 are fixedly mounted on the stirring rod 4. These connecting rods 5 are also distributed in a spiral pattern on the stirring rod 4, with their axes perpendicular to the axis of the stirring rod 4. Scrapers 6, arranged in a spiral pattern, are further fixed to the connecting rods 5. These scrapers 6 are in close contact with the interior of the oil storage tank body 1. When the stirring rod 4 rotates under the drive of the drive motor 7, the scrapers 6 also rotate accordingly, scraping off the sediment adhering to the inner wall of the oil storage tank body 1. This design not only effectively prevents long-term adhesion of sediment in the oil but also allows for regular cleaning of the tank, ensuring the long-term stability of the oil storage tank.

[0039] To drive the stirring rod 4 to rotate, a drive motor 7 is fixedly installed on the outer side wall of the oil storage tank body 1. A worm gear 9 is fixedly sleeved on the shaft 8 of the drive motor 7, and a worm wheel 10 that meshes with the worm gear 9 is fixedly installed at one end of the stirring rod 4. When the drive motor 7 starts, its shaft 8 drives the worm gear 9 to rotate, which in turn drives the stirring rod 4 to rotate through the meshing transmission between the worm wheel 10 and the worm gear 9. This transmission method is not only simple in structure and highly efficient, but also ensures the stable rotation of the stirring rod 4, thereby fully utilizing its functions of stirring and scraping sediment.

[0040] Through its unique stirring mechanism and efficient transmission system design, the device effectively scrapes away sediment from the oil and regularly cleans the oil storage tank. Simultaneously, it ensures the sealing of the oil storage tank when the stirring rod 4 rotates, guaranteeing the quality of the oil and the long-term stability of the storage tank.

[0041] Example 2:

[0042] Based on Embodiment 1, this embodiment further optimizes the oil storage device, particularly in terms of cooling. As the external environment changes, the temperature of the oil in the storage tank may gradually rise, which not only affects the quality of the oil but may also damage the structure of the storage tank. Therefore, this embodiment specifically designs a cooling component 11 to effectively reduce the temperature inside the storage tank, ensuring the quality of the oil and the long-term stability of the storage tank.

[0043] In this embodiment, the cooling assembly 11 mainly consists of a pump 12, cooling pipes 13, and coolant 14. The pump 12 is fixedly mounted on the outer wall of the oil storage tank body 1, and its shaft 8 is fixedly connected to the shaft 8 of the drive motor 7 through a special design. This connection method not only simplifies the structure but also achieves power sharing and reduces energy consumption.

[0044] The pump 12 is connected to a cooling pipe 13 via a pipeline, and the cooling pipe 13 is filled with a high-efficiency coolant 14. To maximize the cooling effect, the cooling pipe 13 is designed to be tightly fitted to the outer wall of the oil storage tank body 1 in a spiral winding form. When the pump 12 is started, the coolant 14 circulates within the cooling pipe 13, absorbing heat from the oil storage tank to reduce the temperature inside the tank.

[0045] Example 3:

[0046] Based on Example 2, this example features a more in-depth structural optimization design for the oil storage device, aiming to further improve its stability, usability, and ease of maintenance. The following is a detailed design description:

[0047] Several bearing seats 15 are fixed on the side wall of the oil storage tank body 1. The bearing seats 15 not only support the rotating shaft 8 of the drive motor 7, but also significantly enhance the stability of the rotating shaft 8 through their unique structural design. At the same time, the bearing seats 15 also have excellent shock absorption function, effectively reducing noise and wear of the rotating shaft 8 caused by vibration, thereby greatly extending the service life of the rotating shaft 8.

[0048] To reduce the impact and vibration of the drive motor 7 on the oil storage tank body 1 during operation, a buffer pad 16 is fixedly installed at the connection between the drive motor 7 and the oil storage tank body 1. This buffer pad 16 is made of high-quality elastic material, which can effectively absorb vibration energy, reduce noise level, and improve the overall stability and service life of the device.

[0049] To facilitate staff observation of the oil level in the storage tank, several observation holes 17 were carefully designed into the top of the tank. Each observation hole 17 is secured with a sealing cap 18. This design ensures the tank's airtightness, preventing oil leakage, while also allowing staff to easily open the cap 18 for observation and operation. This design significantly improves the ease of use and safety of the equipment.

[0050] To protect critical components such as the shaft 8, worm gear 10, and worm 9 of the drive motor 7, a protective cover 19 is fixedly installed on the side wall of the oil storage tank body 1. This protective cover 19 is made of robust and durable materials, effectively preventing dust and debris from entering the transmission system and avoiding damage to critical components or affecting the normal operation of the device. At the same time, the protective cover 19 also has excellent ventilation performance, ensuring good heat dissipation of the transmission system during operation.

[0051] To reduce vibration and noise generated during operation, vibration damping pads 20 are fixedly installed on the base 2. These damping pads 20 are made of high-performance damping materials, which can effectively absorb and disperse vibration energy and reduce noise levels. This design not only improves the stability of the device but also improves the working environment, allowing workers to operate in a more comfortable and quiet environment.

[0052] To facilitate oil output and the hoisting and transportation of the equipment, an oil outlet valve 21 is installed on the main body 1 of the oil storage tank, and a hoisting lug 22 is fixedly installed on the top. The design of the oil outlet valve 21 makes oil output more convenient and faster, while the hoisting lug 22 facilitates the overall hoisting and transportation of the equipment using hoisting equipment. Meanwhile, to facilitate personnel climbing and maintenance of the equipment, a climbing ladder 23 is also fixedly installed on the side wall of the oil storage tank. This design fully considers the actual needs of the personnel, improving the ease of use and maintenance efficiency of the equipment.

[0053] Through the structural optimization design of this embodiment, the high-efficiency oil storage device for oilfield production has been significantly improved in terms of stability, ease of use, and maintenance convenience. This device can better meet the needs of oilfield production operations and provide a more reliable and efficient oil storage solution for oilfield development.

[0054] Working Principle: During use, when the drive motor 7 starts, its shaft 8 drives the worm 9 to rotate. Since the worm 9 and the worm wheel 10 are meshed, the rotation of the worm 9 further drives the worm wheel 10 to rotate. One end of the stirring rod 4 is fixedly mounted on the worm wheel 10; therefore, the rotation of the worm wheel 10 is converted into the rotation of the stirring rod 4. Several connecting rods 5 fixedly mounted on the stirring rod 4 rotate accordingly, while the helically mounted scrapers 6 on the connecting rods 5 rotate along the inner wall of the oil storage tank body 1.

[0055] The scraper 6 is designed to fit tightly against the inner wall of the oil storage tank body 1. As the stirring rod 4 rotates, the scraper 6 can scrape off the sediment on the inner wall, preventing it from accumulating. At the same time, the rotation of the stirring rod 4 also promotes the mixing of oil in the oil storage tank, improving the uniformity of the oil.

[0056] The shaft 8 of the pump 12 is fixedly connected to the shaft 8 of the drive motor 7, so when the drive motor 7 starts, the pump 12 will also start working simultaneously. The pump 12 circulates the coolant 14 to the outer wall of the oil storage tank body 1 through the cooling pipe 13. Since the cooling pipe 13 is arranged in a spiral wound form on the outer wall of the oil storage tank body 1, the coolant 14 can fully contact the oil storage tank body 1, thereby absorbing and carrying away the heat inside the oil storage tank body 1.

[0057] As the coolant 14 circulates in the cooling pipe 13, heat is carried away from the main body of the oil storage tank 1 and dissipated into the air through the heat dissipation effect of the cooling pipe 13. In this way, the temperature inside the main body of the oil storage tank 1 is reduced, ensuring the stability and safety of the oil.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
