Description

Technical Field

[0002] Oil storage tanks are containers for storing crude oil or other petroleum products, and are commonly used in refineries, oil fields, oil depots, and other industries. During the storage of oil products, due to the influence of the temperature difference between day and night, there is a situation where volatile substances in the oil products evaporate, and because the volume of the oil storage tank is fixed, the volatile gas will destroy the pressure balance in the oil storage tank. To solve this problem, the existing technology usually installs a breathing valve on the oil storage tank. When the oil and gas pressure in the tank is greater than the allowable pressure of the oil tank, the oil vapor escapes through the pressure valve, and the vacuum valve is in a closed state at this time; when the oil and gas pressure in the tank is less than the allowable vacuum degree of the oil tank, fresh air enters the tank through the vacuum valve, and the pressure valve is in a closed state at this time. During this process, the amount of oil in the oil storage tank is constantly decreasing, which will greatly reduce the economic benefits; based on this, the present application proposes an oil storage tank that is easy to adjust and balance.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides an oil storage tank that is easy to adjust and balance, including a tank body 1. The outer surface of the tank body 1 is wrapped with a heat insulation pad 14. The heat insulation pad 14 can reduce the influence of the external temperature on the temperature of the oil stored in the tank body 1 and improve the stability of the oil temperature. The heat insulation pad 14 can be made of pearl cotton.

[0023] The sidewalls of the tank body 1 are hollow structures. They include an outer wall 15 and an inner wall 16 fixedly connected to the inner cavity of the outer wall 15. The inner wall 16 and the outer wall 15 form a cavity 1. The inner cavity of the cavity 1 is filled with a liquid such as water. The inner cavity of the cavity 1 is alternately provided with cooling structures and heating structures. The cooling structure includes a refrigerator 11 and a heat-conducting rod 13 fixedly connected to the cold end of the refrigerator 11. The heat-conducting rod 13 can be made of a metal tube to conduct heat and accelerate the cooling rate of the liquid in the cavity 1. The hot end of the refrigerator 11 is located outside the cavity 1. The refrigerator 11 can be a semiconductor refrigerator.

[0024] The heating structure includes a heating rod 12, which is alternately arranged with a heat conducting rod 13. Through the arrangement of the heating rod 12, when the heating rod 12 is powered on, the heat generated by the heating rod 12 can heat the liquid in the cavity.

[0025] An air cooling chamber 3 is provided at the bottom of the tank body 1. The hot end of the cooling structure is located within the inner cavity of the cooling chamber 3. An exhaust fan 10 is fixedly connected to the inner cavity of the cooling chamber 3. The air outlet of the exhaust fan 10 extends to the outside of the cooling chamber 3 through the air outlet pipe 8. The air inlet of the exhaust fan 10 is located within the inner cavity of the cooling chamber 3. An air inlet hole 9 is provided on the side of the cooling chamber 3 away from the air outlet pipe 8. Through the provision of the exhaust fan 10, the operation of the exhaust fan 10 can discharge the air in the cooling chamber 3 to the outside. The air in the outside cavity enters the cooling chamber 3 through the air inlet hole 9, which speeds up the air flow in the cooling chamber 3, thereby increasing the heat dissipation speed of the hot end of the refrigerator and facilitating the operation of the cooling structure.

[0026] It can be seen from the above description that when the oil storage tank is in use, it can actively heat up or cool down the oil stored in the tank body 1, so that the temperature of the oil remains stable and the breathing loss of the oil is reduced.

[0027] A base 4 is provided at the bottom of the air cooling chamber 3, and a weighing sensor is fixed on the top of the base 4. Through the setting of the weighing sensor, the amount of oil stored in the tank body 1 can be detected, which facilitates the controller of the oil storage tank to determine whether the amount of oil in the tank is increasing or decreasing.

[0028] The top of the tank 1 is provided with an expansion chamber 2. An inflatable airbag 25 is fixedly connected to its interior.

A fixing hole is provided in the middle of the expansion chamber 2. An electric telescopic rod 6 is fixedly connected to its interior. The end of the output shaft of the electric telescopic rod 6 passes through the top of the tank 1 and extends into the interior of the tank 1. The output shaft of the electric telescopic rod 6 is movably connected to the top of the tank 1 and fixedly connected to the top of a lifting plate 17. The lifting plate 17 is movably connected to the interior of the tank 1. The extension and retraction of the electric telescopic rod 6 can change the position of the lifting plate 17 to which it is fixed. As the lifting plate 17 moves, the effective volume within the tank 1 changes. This ensures that the air pressure above the oil product is maintained consistent during the oil storage tank's delivery and reception operations, reducing the probability of significant breathing losses caused by rapid changes in oil volume.

[0029] A pressure sensor 20, a temperature sensor 21, a one-way air intake valve 18 and a one-way exhaust valve 19 are provided at the bottom of the lifting plate 17. The exhaust end of the one-way air intake valve 18 and the air intake end of the one-way exhaust valve 19 are at the same height as the bottom of the lifting plate 17. The air intake end of the one-way air intake valve 18 is fixedly connected to a telescopic tube 2, and the exhaust end of the one-way exhaust valve 19 is fixedly connected to a telescopic tube 3. The other ends of the telescopic tube 2 and the telescopic tube 3 extend into the inner cavity of the inflatable airbag 25. Through the setting of the one-way exhaust valve 19, the oil and gas in the tank body 1 can enter the inner cavity of the inflatable airbag 25, and the oil and gas can be temporarily stored in the inflatable airbag 25. Through the setting of the one-way air intake valve 18, the oil and gas in the inflatable airbag 25 can flow back to the inner cavity of the tank body 1, thereby reducing the small breathing loss of the oil.

[0030] The materials of the telescopic tube 1, the telescopic tube 2 and the telescopic tube 3 can all be high-pressure bellows.

[0031] An oil pipe 7 is installed on one side of the tank body 1. The top of the oil pipe 7 is located above the expansion chamber 2, and the bottom of the oil pipe 7 extends to the bottom end of the inner cavity of the tank body 1. The lifting plate 17 is movably connected to the oil pipe 7, and the lifting plate 17 and the oil pipe 7 are sealed by a sealing ring. The installation of the oil pipe 7 facilitates the sending and receiving operations of the oil tank. A ball valve is installed at the top of the oil pipe 7, which can be used to control the opening and closing of the oil pipe 7.

[0032] The outer surface of the expansion chamber 2 is wrapped with a heat preservation pad 14, the side wall of the expansion chamber 2 is a hollow structure, the expansion chamber 2 comprises an outer wall two 24 and an inner wall two 22 fixedly connected with the inner cavity of the outer wall two 24, a cavity two is formed between the outer wall two 24 and the inner wall two 22, the cavity two is filled with liquid such as water, the top of the cavity one and the bottom of the cavity two are fixedly connected with a through hole 23, the cavity one and the cavity two are communicated through the through hole 23, through the arrangement of the through hole 23, the cooling structure and the heating structure can regulate the temperature of the oil gas in the inflatable air bag 25, and the loss of oil gas is reduced.

[0033] As can be seen from the above description, the volume of the oil tank can be changed according to the demand, the oil breathing loss is reduced, and the evaporated oil gas can be trapped, the trapped oil gas can flow back to the inner cavity of the tank body 1, and the oil breathing loss is further reduced.

The specific connection and control sequence are described below, and the working order of each electric device is completed, and the detailed connection means is a known technology in the art. The working principle and process are mainly introduced below, and the electric control is not described.

[0035] As described above, when the oil tank is used, the oil liquid enters and exits the tank body 1 through the oil pipe 7, and during the oil liquid receiving and transmitting operation, the electric telescopic rod 6 drives the lifting plate 17 to move, so that the air pressure between the lifting plate 17 and the oil liquid remains unchanged, the breathing loss during the oil liquid receiving and transmitting operation is reduced, and when the top of the lifting plate 17 is tightly attached to the top of the tank body 1, the oil is injected into the tank body 1, the excess air in the tank body 1 enters the inner cavity of the inflatable air bag 25 through the one-way exhaust valve 19, and the oil gas loss is avoided. During the storage of the oil liquid, the temperature sensor 21 detects the temperature in the tank body 1 in real time, and adjusts the temperature in the tank body 1 through the cooling structure or the heating structure, so as to reduce the evaporation amount of the oil liquid and reduce the oil loss.
