Description

Technical Field

[0001] This utility model relates to the field of petroleum storage technology, and more specifically, to a petroleum storage device that can reduce volatilization. Background Technology

[0002] During long-term storage in oil tanks, changes in ambient temperature and diurnal temperature variations can cause oil to volatilize, leading to the accumulation of oil vapors in the cavity at the top of the tank. This increases internal pressure and poses a risk of leakage. Exposure to open flames, static electricity, or lightning strikes can easily trigger a fire. To address this issue, current technology typically involves installing refrigeration devices on the outside of the tank. By lowering the overall temperature of the tank, the intensity of oil volatilization is reduced, thereby controlling the amount of oil vapor generated and the pressure rise, ultimately improving safety.

[0003] For example, patent application number 202122050018.0 discloses a storage device for oil transportation that reduces evaporation, including a shell, an oil inlet pipe, an oil outlet pipe, an air extraction pipe, a sealing cap, an air pump, an oil tank body, and a cooler. The cooler stabilizes the internal pressure and temperature of the device, making it less prone to oil evaporation. However, in the above-mentioned oil transportation storage device, the cooler is only transported through a transmission pipe, resulting in uneven distribution of the cooler during the transmission process. This is especially true above the oil tank body and at the end furthest from the cooler, where the cooler arrives slowly and covers the area insufficiently, resulting in poor cooling in that area and a decrease in overall cooling efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an oil storage device that can reduce volatilization, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A petroleum storage device with reduced evaporation includes: a petroleum storage tank; a protective outer shell connected to the outside of the petroleum storage tank; a cooler unit disposed at one end of the protective outer shell; several damping mechanisms disposed between the outside of the petroleum storage tank and the inner wall of the protective outer shell; a transmission channel disposed between the petroleum storage tank and the protective outer shell; a blower mechanism disposed inside the transmission channel near the cooler unit for delivering cool air; a control panel disposed at the other end of the protective outer shell; a pressure sensor disposed at the other end of the petroleum storage tank; an oil inlet pipe connected to the protective outer shell is connected to the top of the petroleum storage tank, and a sealing cap is provided at the top of the oil inlet pipe; an air pump is disposed at the middle of the top of the petroleum storage tank, and an air extraction pipe connected to the petroleum storage tank and the protective outer shell is disposed at the bottom of the air pump; an oil extraction pump connected to the petroleum storage tank is disposed on one side of the air pump, and an oil extraction pipe connected to the petroleum storage tank and the protective outer shell is disposed at the bottom of the oil extraction pump; and an exhaust pipe is disposed at the other end of the protective outer shell.

[0008] Furthermore, to improve the utilization rate and smooth circulation of the cooling air, the special structure of the annular frame and annular cavity allows the cooling air to be ejected at high speed from the air outlet under high pressure, forming a stable and wide-coverage airflow. This airflow not only quickly delivers the cooling air to the surface of the oil storage tank, but also drives the surrounding airflow, preventing short-circuiting or stagnation of the cooling air, while maintaining uniform indoor air circulation, thereby achieving a more efficient and energy-saving cooling effect. This ensures that the cooling air evenly surrounds the tank, effectively reducing oil evaporation caused by excessively high local temperatures. The blower mechanism includes: a protective shell, located at the inner bottom of the transmission channel near the air conditioner; an air inlet, located on the outer side of the protective shell; a motor, located inside the protective shell; an impeller, located at the top of the motor; an annular frame, located at the top of the protective shell and connected to it; an annular cavity, located inside the annular frame; and an air outlet, located on the inner side of the annular frame and connected to the annular cavity.

[0009] Furthermore, in order to further improve the circulation efficiency of the cold air, the speed and pressure of the airflow can be more effectively coordinated and matched under the action of the annular cavity teardrop-shaped structure, so that the cold air is accelerated during the delivery process, thereby significantly improving the circulation efficiency and overall cooling performance of the cold air. The cross-section of the annular cavity is a teardrop-shaped structure; the air outlet is located on the side close to the air conditioner.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through the coordinated arrangement of an oil storage tank, protective shell, air cooler, damping mechanism, blower mechanism, transmission channel, control panel, and pressure sensor, not only reduces the overall temperature of the oil storage tank and decreases the volatility of oil, thereby improving safety; but also optimizes the cooling air delivery path by leveraging the synergistic effect of the blower mechanism and transmission channel, avoiding uneven distribution of cooling air during transmission. In particular, it enables rapid and uniform cooling at the top of the oil storage tank and at the end of the oil storage tank away from the cooling air inlet, improving overall cooling efficiency and effectively solving the problems of increased volatilization and energy waste caused by local temperature differences in existing technologies.

[0012] 2. Through the blower mechanism, under the special structure of the annular frame and annular cavity, cold air is ejected at high speed from the air outlet under high pressure, forming a stable and wide-coverage airflow. This airflow can not only quickly deliver cold air to the surface of the oil storage tank, but also drive the surrounding air flow, avoiding cold air short-circuiting or stagnation, while maintaining uniform indoor air circulation, thereby achieving a more efficient and energy-saving cooling effect, ensuring that the cold air is evenly surrounding the tank, and effectively reducing oil volatilization caused by excessively high local temperatures.

[0013] 3. Through the annular cavity, under the guidance of the teardrop-shaped structure, the speed and pressure of the airflow can be more effectively coordinated and matched, which accelerates the cold air during the delivery process, thereby significantly improving the circulation efficiency of the cold air and the overall cooling performance.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] According to an embodiment of the present invention, an oil storage device that can reduce volatilization is provided.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the petroleum storage device with reduced evaporation according to an embodiment of the present invention includes: a petroleum storage tank 1; a protective shell 2 connected to the outside of the petroleum storage tank 1; a cooler 3 disposed at one end of the protective shell 2; a plurality of damping mechanisms 4 disposed between the outside of the petroleum storage tank 1 and the inner wall of the protective shell 2; a transmission channel 6 disposed between the petroleum storage tank 1 and the protective shell 2; a blower mechanism 5 disposed inside the transmission channel 6 near the cooler 3 for conveying cool air; a control panel 7 disposed at the other end of the protective shell 2; and a pressure sensor 8 disposed at the petroleum storage tank 1. At the other end of tank 1; the top of oil storage tank 1 is connected to an oil inlet pipe 101 connected to a protective shell 2, and a sealing cap 102 is provided at the top of the oil inlet pipe 101; an air pump 103 is provided at the middle of the top of oil storage tank 1, and an air extraction pipe 104 connected to oil storage tank 1 and protective shell 2 is provided at the bottom of the air pump 103; an oil extraction pump 105 connected to oil storage tank 1 is provided on one side of the air pump 103, and an oil extraction pipe 106 connected to oil storage tank 1 and protective shell 2 is provided at the bottom of the oil extraction pump 105; an exhaust pipe 201 is provided at the other end of the protective shell 2.

[0024] In one embodiment, the blower mechanism 5 includes: a protective shell 501 disposed at the inner bottom of the transmission channel 6 near the air conditioner 3; an air inlet 502 opened on the outer side of the protective shell 501; a motor 503 disposed inside the protective shell 501; an impeller 504 disposed at the top of the motor 503; an annular frame 505 disposed at the top of the protective shell 501 and connected thereto; an annular cavity 506 opened inside the annular frame 505; and an air outlet 507 opened on the inner side of the annular frame 505 and connected to the annular cavity 506. The cross-section of 6 is teardrop-shaped; the air outlet 507 is located on the side close to the air conditioner 3; under the special structure of the annular frame 505 and the annular cavity 506, the cold air is ejected from the air outlet 507 at high speed under high pressure, forming a stable and wide-coverage airflow. This airflow can not only quickly deliver the cold air to the surface of the oil storage tank 1, but also drive the surrounding air flow, avoid the phenomenon of cold air short circuit or stagnation, and at the same time maintain the uniform air circulation in the room, thereby achieving a more efficient and energy-saving cooling effect, ensuring that the cold air is evenly surrounding the tank, and effectively reducing the volatilization of oil caused by excessive local temperature.

[0025] The working principle of the blower mechanism 5 is as follows: Based on air multiplication technology, similar to the operation of a bladeless fan, the cold air located at the bottom of the transmission channel 6 enters the protective shell 501 through the air inlet 502. The drive motor 503 drives the impeller 504 to rotate at high speed, compressing the cold air and guiding it into the annular cavity 506, thus achieving cold air circulation and delivery. Due to the teardrop-shaped cross-section design of the annular cavity 506, the airflow velocity at the air outlet 507 is relatively high, resulting in a local pressure reduction in this area, thereby forming a good airflow guiding effect, which is conducive to smooth airflow and effective pressure concentration. Under the action of pressure difference, the cold air can be ejected at high speed from the air outlet 507 on the inner side of the annular frame 505, forming a strong and stable airflow jet. This airflow jet can not only quickly deliver the cold air to the surface of the oil storage tank 1, but also drive the surrounding air to flow together, realizing the "air multiplication" effect, thereby achieving efficient circulation and continuous output of cold air. This not only enhances the air delivery effect, but also improves the overall operating efficiency of the refrigeration system, thereby effectively suppressing oil evaporation and improving the overall safety and operating efficiency of the storage tank.

[0026] In one embodiment, the annular cavity 506 has a teardrop-shaped cross-section; the air outlet 507 is located on the side close to the air conditioner 3; under the action of the teardrop-shaped structure of the annular cavity 506, the speed and pressure of the airflow can be more effectively coordinated and matched, so that the cold air is accelerated during the delivery process, thereby significantly improving the circulation efficiency of the cold air and the overall cooling performance.

[0027] In addition, it should be noted that the air cooler 3 is responsible for generating cold air to reduce the temperature of the tank and reduce the evaporation of oil. The air cooler 3 consists of a compressor, condenser, expansion valve, evaporator and control system. It absorbs and releases heat through the circulation of refrigerant, thereby cooling the oil storage tank. The air cooler 3 is existing technology and will not be elaborated on here.

[0028] In addition, it should be noted that the damping mechanism 4 is used to absorb and reduce external vibrations and protect the stability of the internal structure. The damping mechanism 4 includes elastic material, shock absorber and fixed support, and is used to absorb external vibrations and protect the safety of the tank structure. The damping mechanism 4 is existing technology and will not be elaborated on here.

[0029] In addition, it should be noted that the control panel 7 consists of a human-machine interface (HMI) and a programmable logic controller (PLC). This control panel 7 is existing technology and will not be elaborated on further here.

[0030] In addition, it should be noted that an electromagnetic valve is installed inside the oil inlet pipe 101. This electromagnetic valve can precisely control the oil inlet process. This electromagnetic valve is existing technology and will not be elaborated on here.

[0031] In addition, it should be noted that a silicone sheet is provided at the bottom of the vent pipe 104. The silicone sheet is used to achieve one-way gas flow, prevent liquid overflow, and maintain the gas pressure balance inside the oil storage tank 1. The connection between the silicone sheet and the vent pipe 104 can be achieved by adhesive bonding, embedded installation, or mechanical fixing. The silicone sheet is existing technology and will not be elaborated on here.

[0032] In addition, it should be noted that a pressure sensor is installed at the bottom of the silicone sheet to monitor the air pressure changes inside the oil storage tank 1 in real time and transmit the air pressure signal to the control panel 7. The control panel 7 then controls the air pump 103 to regulate the air pressure. This pressure sensor is existing technology and will not be elaborated on here.

[0033] Furthermore, it should be noted that an electromagnetic valve is installed inside the exhaust pipe 201. The electromagnetic valve inside the exhaust pipe 201 is used to control exhaust gas emissions and maintain an appropriate pressure level between the oil storage tank 1 and the protective shell 2. The entire device works in concert to effectively improve the safety and efficiency of oil storage. The electromagnetic valve is mainly composed of a valve body, an electromagnetic coil, and an iron core. The electromagnetic coil generates a magnetic field by controlling the current, which drives the iron core to move to open or close the valve, thereby achieving precise control of the fluid flow in the oil inlet pipe 101 and the exhaust pipe 201. This electromagnetic valve is existing technology and will not be elaborated on further here.

[0034] In addition, it should be noted that the pressure sensor 8 is used to monitor the air pressure change between the oil storage tank 1 and the protective shell 2 to ensure operation within a safe range, and transmits the air pressure signal to the control panel 7, which then controls the solenoid valve inside the exhaust pipe 201 to regulate the air pressure. This pressure sensor 8 is existing technology and will not be elaborated on further here.

[0035] In addition, it should be noted that the air pump 103 includes a motor, a piston or diaphragm, and an air inlet and outlet. The motor drives the piston or diaphragm to move, changing the internal volume, thereby drawing in external air and discharging it through the air extraction pipe 104, regulating the air pressure inside the tank and maintaining a stable state. When it is necessary to deliver oil to the oil inlet pipe 101, the air pump 103 is started to ensure that the oil inlet pipe 101 is unobstructed. This air pump 103 is prior art and will not be described in detail here.

[0036] In addition, it should be noted that the oil pump 105 is usually composed of a motor, impeller or gear system. The motor drives the impeller to rotate and generate suction, which draws oil from the oil storage tank 1 through the oil extraction pipe 106 to ensure efficient and safe oil output. This oil pump 105 is existing technology and will not be elaborated on here.

[0037] In addition, it should be noted that the control panel 7 is electrically connected to the air conditioner 3, the blower mechanism 5, the solenoid valve, the air pump 103, the oil pump 105, and the pressure sensor 8.

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] In practical application, the air conditioner 3 and blower mechanism 5 are first activated via control panel 7 to generate cold air. This cold air is then evenly distributed around the oil storage tank 1 via blower mechanism 5 and transmission channel 6, thus controlling the internal temperature of the tank within a safe range. During the cold air transmission process, pressure sensor 8 monitors the pressure changes between the oil storage tank 1 and the protective outer shell 2, transmitting the pressure signal to control panel 7. Control panel 7 then regulates the air pressure using the solenoid valve inside exhaust pipe 201, ensuring operation within a safe range. Subsequently, the sealing cap 102 at the top of oil inlet pipe 101 is opened, and oil or gasoline is injected into the oil storage tank 1 through the inlet pipe. During the injection process, the one-way valve of the solenoid valve inside the inlet pipe ensures that liquid can only flow into the tank in one direction, preventing oil leakage or evaporation due to pressure changes. At the same time, the air pump 103 is started to ensure that the oil inlet pipe 101 is unobstructed. The air pump 103 can also be used to regulate the air pressure inside the tank. The pressure sensor in the air extraction pipe 104 monitors the air pressure changes inside the oil storage tank 1 in real time and transmits the pressure signal to the control panel 7. The control panel 7 controls the air pump 103 to regulate the air pressure, so that the air pressure inside the tank is kept stable and to avoid safety hazards caused by excessive pressure, until the oil filling is completed.

[0040] Simultaneously, the damping mechanism 4 can prevent structural damage caused by collisions during the transportation of the oil storage device, and the outlet is connected to the oil pump 105 via the oil outlet interface. The oil pump 105 can be started via the control panel 7, and the oil inside the tank is extracted through the oil extraction pipe 106. Oil extraction pipe 106.

[0041] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the oil storage tank 1, protective shell 2, air cooler 3, damping mechanism 4, blower mechanism 5, transmission channel 6, control panel 7, and pressure sensor 8, it is possible not only to reduce the overall temperature of the oil storage tank 1 and decrease the volatility of oil, thereby improving safety; but also, through the synergistic effect of the blower mechanism 5 and the transmission channel 6, the cooling air delivery path is optimized, avoiding uneven distribution of cooling air during transmission. Especially at the top of the oil storage tank 1 and the end of the oil storage tank 1 away from the cooling air inlet, rapid and uniform cooling can be achieved, improving overall cooling efficiency and effectively solving the problems of increased volatilization and energy waste caused by local temperature differences in existing technologies. Through the blower mechanism 5, under the special structure of the annular frame 505 and the annular cavity 506, cold air is ejected at high speed from the air outlet 507 under high pressure, forming a stable and wide-coverage airflow jet. This airflow jet can not only quickly deliver cold air to the surface of the oil storage tank, but also drive the surrounding airflow, avoiding short-circuiting or stagnation of cold air, while maintaining uniform indoor air circulation, thereby achieving a more efficient and energy-saving cooling effect, ensuring that the cold air is evenly surrounding the tank, and effectively reducing oil volatilization caused by excessively high local temperatures. Through the annular cavity 506, under the guidance of the teardrop-shaped structure, the speed and pressure of the airflow can be more effectively coordinated and matched, accelerating the cold air during the delivery process, thereby significantly improving the circulation efficiency of the cold air and the overall cooling performance.
