Description

Technical Field

[0001] This utility model belongs to the field of petroleum storage technology, and in particular relates to a petroleum storage device for petrochemical transportation. Background Technology

[0002] In the petrochemical industry, the transportation and storage of petroleum are crucial links. As a flammable, explosive, and volatile liquid, petroleum faces many challenges during transportation.

[0003] Existing oil storage facilities have some shortcomings in their structural design. On the one hand, during transportation, due to vehicle bumps, sudden braking, and other operations, the oil will violently shake inside the storage tank, generating a large impact force. This impact force will not only cause wear to the inner wall of the storage tank and shorten its service life, but may also affect the stability of the entire transportation device and increase safety hazards during transportation.

[0004] On the other hand, during the storage and transportation of oil, gas may be generated due to factors such as temperature changes and chemical reactions, which may cause the internal pressure of the storage tank to rise. If the pressure cannot be released in time, when the pressure exceeds the storage tank's tolerance limit, it may cause serious accidents such as explosions, posing a huge threat to the safety of people's lives and the surrounding environment.

[0005] To address these issues, we provide a petroleum storage device for petrochemical transportation. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a petroleum storage device for petrochemical transportation, including a storage tank. The storage tank is equipped with partitions that are fixedly connected at equal intervals inside. A valve is installed at the oil drain hole of the storage tank. A pressure relief valve is fixedly connected to the top of the surface of the storage tank.

[0008] Wherein: rectangular grooves are provided at both ends of the lower surface of the pressure relief valve; pressure relief holes are provided in a rectangular array on the upper surface of the middle part of the inner wall of the pressure relief valve; two filter pads are fixedly installed on the upper surface of the inner wall of the pressure relief valve; and exhaust holes are provided at equal intervals in a rectangular array on the surface of the filter pads.

[0009] The present invention is further configured such that push plates are provided at both ends of the inner wall of the pressure relief valve, the lower surface of the push plates is adapted to the inner wall of the rectangular groove, and a retraction rod is fixedly connected to the upper surface of the push plates, the top end of the retraction rod is fixedly installed on the lower surface of the middle part of the inner wall of the storage tank.

[0010] The present invention is further configured such that springs are sleeved on the outer side of the retraction rod, and the two ends of the springs are fixedly connected to the lower surface of the middle part of the inner wall of the pressure relief valve and the upper surface of the push plate, respectively.

[0011] The present invention is further configured such that a support block is provided on the lower surface of the storage tank, the support block is fixedly connected to the storage tank through a base plate, an oil injection pipe is fixedly installed in the middle of the upper surface of the storage tank, and a sealing cap is threadedly connected to the top end of the oil injection pipe on the upper surface of the storage tank.

[0012] The present invention is further configured such that both ends of the lower surface of the partition are fixedly connected to support legs, and the other end of each support leg is fixedly installed on the lower surface of the inner wall of the storage tank. There are oil flow gap grooves between the upper and lower surfaces of the partition and the inner wall of the storage tank.

[0013] The present invention is further configured such that a valve block is rotatably connected to the inner wall of the valve, a rotating rod is fixedly connected to the top of the valve block, and connecting pipes are fixedly connected to both ends of the valve. The valve is fixedly installed at the oil drain hole of the storage tank through one of the connecting pipes.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model utilizes partitions fixedly connected at equal intervals inside a storage tank, dividing the internal space of the tank into multiple smaller spaces. Simultaneously, oil flow gaps are provided between the upper and lower surfaces of the partitions and the inner wall of the storage tank, allowing oil to flow between the multiple smaller spaces. This structural design effectively reduces the impact force caused by oil shaking during transportation, reduces wear on the inner wall of the storage tank, improves the stability of the entire transportation device, and ensures the safety of the transportation process.

[0016] 2. This utility model features a unique and reasonable pressure relief valve design. When the internal pressure of the storage tank is too high, the air pressure pushes the push plate, opening the rectangular slot. This allows the gas inside the storage tank to pass sequentially through the rectangular slot and the pressure relief hole into the top of the pressure relief valve's inner cavity. After being filtered and adsorbed by the filter pad, it is discharged into the external environment. This process not only achieves timely pressure relief inside the storage tank, preventing accidents such as explosions caused by excessive pressure and improving the safety of the device, but also allows the filter pad to effectively adsorb harmful substances in the gas, reducing environmental pollution. When the internal pressure of the storage tank returns to normal, the spring will push the push plate back to its original position through its own elasticity, sealing the rectangular slot. This convenient operation further improves the practicality of the device. Attached Figure Description

The lower surface and the upper surface of the push plate 403 are fixedly connected. In use, when the pressure inside the storage tank 1 is too high, the pressure will push the push plate 403 through the pressure relief valve 4, thereby opening the rectangular groove 401. At this time, the gas inside the storage tank 1 will enter the top of the inner cavity of the pressure relief valve 4 through the rectangular groove 401 and the pressure relief hole 402, and then be discharged into the external environment through the filter pad 406. This achieves pressure relief inside the storage tank 1 and improves the stability of the device. When the pressure inside the storage tank 1 is restored, the spring 405 will push the push plate 403 with its own elastic force to reset it, thereby sealing the rectangular groove 401 and improving the convenience of the device.

[0026] Specifically, a support block 101 is provided on the lower surface of the storage tank 1. The support block 101 is fixedly connected to the storage tank 1 through the base plate 102.

[0027] Specifically, both ends of the lower surface of the partition 2 are fixedly connected to support legs 201, and the other end of the support legs 201 is fixedly installed on the lower surface of the inner wall of the storage tank 1. There are oil flow gap grooves between the upper and lower surfaces of the partition 2 and the inner wall of the storage tank 1. In use, the partition 2 can divide the internal space of the storage tank 1 into multiple small spaces, and the multiple small spaces flow between each other through the gap grooves between the partition 2 and the storage tank 1, thereby reducing the impact force generated by the swaying of oil during transportation and improving the stability of the device.

[0028] Specifically, a valve block 301 is rotatably connected to the inner wall of valve 3, and a rotating rod 302 is fixedly connected to the top of valve block 301. Both ends of valve 3 are fixedly connected to connecting pipes 303. Valve 3 is fixedly installed at the oil drain hole of storage tank 1 through a connecting pipe 303. In use, when it is necessary to adjust the oil drain flow rate of the device, the valve block 301 can be driven by rotating the rotating rod 302 to adjust the flow rate, which helps to improve the flexibility of the device.
