Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically a high-sealing vacuum buffer tank for petrochemical applications. Background Technology

[0002] In the processes of oil refining, chemical production and transportation, pressure pulsation and flow oscillation are easily generated due to the influence of factors such as the flow characteristics of the medium and changes in flow rate. Buffer tanks, as shock absorption and buffering devices, can effectively absorb the influence of these factors and keep the pipeline stable.

[0003] Chinese patent discloses a transfer device for an acid buffer tank in petrochemical industry (authorization announcement number CN216467989U). This patented technology, by setting up a support column, transmission rod, movable plate, buffer spring, support plate and buffer layer, can buffer the external vibration force during the transfer of acid buffer tank, and avoid the acid inside the buffer tank from shaking, which could easily cause the acid to overflow. This improves the safety of acid buffer tank transfer. However, the liquid inside the tank may still impact the tank body, which could lead to a safety accident. Utility Model Content

[0004] The purpose of this invention is to provide a high-sealing vacuum buffer tank for petrochemical applications to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-sealing vacuum buffer tank for petrochemical applications includes a tank body. The tank body has several partitions inside, and an air bladder is located at the upper end of each partition inside the tank body. An inflation valve is located on one side of the upper end of each air bladder, and an exhaust valve is located on the other side. Each partition has a connecting port at its bottom, and a turntable is rotatably connected to the inner side of each connecting port. A long shaft is fixedly connected to the upper end of the turntable, and a motor is mounted on the upper end of the long shaft.

[0006] As a further embodiment of this utility model: the motor is fixedly installed on the upper part of the outer side of the tank, and a guide sleeve is provided on the upper part of one side of the partition, and the long shaft slides through the inner side of the guide sleeve.

[0007] As a further improvement of this utility model: a feeding port is provided on one side of the upper end of the tank, and a discharge port is provided on the other side of the lower end of the tank.

[0008] As a further improvement of this utility model: a pressure gauge is provided on the upper end of the tank away from the feeding port, and a safety valve is provided on the upper end of the tank near the pressure gauge.

[0009] As a further improvement of this utility model: the outer wall of the airbag is provided with a number of grooves, and a storage line is provided through the inner side of the grooves.

[0010] As a further embodiment of this utility model: a second motor is provided on the outer side of the tank near the motor, and a drum is fixedly connected to the output end of the second motor. One end of the receiving line passes through the outer side of the tank and is connected to the drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention divides the tank into several independent spaces at the bottom and interconnected spaces at the top using partitions. When the volume of petrochemical liquid stored in the tank is lower than the highest point of the partitions, the petrochemical liquid is stored in separate spaces, which reduces the flow of the petrochemical liquid in the tank and thus reduces the impact on the tank. When the liquid level in the tank exceeds the highest point of the partitions, gas is injected into the air bladder through the inflation valve. The gas causes the air bladder to expand and fill the space above the liquid in the tank, which effectively prevents liquid sloshing and ensures the safety of petrochemical liquid storage.

[0014] Please see Figures 1-4In this embodiment of the present invention, a high-sealing vacuum buffer tank for petrochemical applications includes a tank body 1. The tank body 1 has several partitions 4 inside, dividing it into several spaces that are independent at the bottom but interconnected at the top. When the amount of petrochemical liquid stored in the tank body 1 is lower than the highest point of the partitions 4, the petrochemical liquid is stored in separate spaces, reducing the flow of the petrochemical liquid within the tank body 1 and thus reducing the impact on the tank body 1. Furthermore, an airbag 2 is located above the partitions 4 inside the tank body 1. An inflation valve 6 is located on one side of the upper end of the airbag 2, and an exhaust valve 14 is located on the other side. When the liquid level in the tank body 1 exceeds the highest point of the partitions 4, gas is injected into the airbag 2 through the inflation valve 6. The gas causes the airbag 2 to expand, filling the space above the liquid in the tank body 1, effectively preventing liquid sloshing. When the airbag 2 does not need to expand, the exhaust valve 14 is opened to release the gas from the airbag 2.

[0015] exist Figure 1 In this tank, a feeding port 3 is provided on one side of the upper end of the tank body 1, and a discharge port 10 is provided on the other side of the lower end of the tank body 1. Petrochemical liquid can be added into the tank body 1 through the feeding port 3, and petrochemical liquid can be discharged from the tank body 1 through the discharge port 10. A pressure gauge 7 is provided on the upper end of the tank body 1 away from the feeding port 3, and a safety valve 8 is provided on the upper end of the tank body 1 near the pressure gauge 7. When some of the petrochemical liquid in the tank body 1 evaporates and forms gas, the pressure in the tank body 1 can be monitored through the pressure gauge 7. When the pressure in the tank body 1 is too high, some gas can be discharged through the safety valve 8 to ensure that the pressure in the tank body 1 is stable.

[0016] exist Figure 3 and Figure 4 In the tank, the outer wall of the airbag 2 is provided with several grooves 15, and a storage line 16 is provided through the inner side of the grooves 15. A motor 17 is provided on the outer side of the tank 1 near the motor 5. The output end of the motor 17 is fixedly connected to a drum 18. One end of the storage line 16 passes through the outer side of the tank 1 and is connected to the drum 18. The junction of the storage line 16 and the tank 1 is filled with sealing material to prevent leakage. When the airbag 2 needs to be stored, the drum 18 is rotated by the motor 17, so that the storage line 16 is wound on the drum 18, and the airbag 2 can be stored in the upper part of the tank 1. Conversely, when the airbag 2 needs to be inflated, the storage line 16 is unwound by the drum 18. After the airbag 2 inflates, the storage line 16 can be opened.

[0017] exist Figure 1 and Figure 4In this system, each partition 4 has a connecting port 11 at its bottom. A turntable 12 is rotatably connected to the inner side of the connecting port 11. A long shaft 9 is fixedly connected to the upper end of the turntable 12. A motor 5 is installed on the upper end of the long shaft 9, which is fixedly installed on the upper outer side of the tank body 1. The upper end of the long shaft 9 passes through the inner side of the tank body 1 and is connected to the output end of the motor 5. A sealing ring is provided at the junction of the long shaft 9 and the tank body 1 to prevent leakage at the junction. A guide sleeve 13 is provided on the upper side of one side of the partition 4. The long shaft 9 slides through the inner side of the guide sleeve 13. When it is necessary to store petrochemical liquid evenly in the space divided by the tank body 1, the long shaft 9 is rotated by the motor 5. The long shaft 9 drives the turntable 12 to rotate inside the connecting port 11, which opens the connecting port 11, allowing the petrochemical liquid to flow into each space. When it is necessary to prevent the flow of petrochemical liquid, the connecting port 11 is blocked by the turntable 12.

[0018] 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.
