Description

Technical Field

[0001] This utility model relates to the field of oil and gas transportation, specifically an oil tank spillage prevention device. Background Technology

[0002] In the storage and transportation of oil and gas, transferring oil from tanks is a common operation. However, during the transfer process, the fuel inside the tank may rotate due to the sloshing of the liquid or the action of external forces. This rotation can not only affect the smooth progress of the transfer operation but may also damage the tank and its auxiliary equipment, or even cause a safety accident.

[0003] To address the issue of fuel rotation during oil tank dumping, several anti-rotation devices have been developed and implemented. These devices primarily prevent tank rotation by adding support structures, limiting the tank's range of motion, or utilizing physical barriers. During oil dumping operations, because the drain pipe's suction inlet is located at the bottom of the tank, it is prone to swirling due to the Earth's rotation. This causes the drain pipe to draw in external air, reducing the suction power of the drain pump and affecting normal dumping operations. Utility Model Content

[0004] The purpose of this invention is to provide an anti-spillage device for oil tanks to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-swirl device for oil tank spillage includes a first top plate, an anti-swirl baffle, a second top plate, a buffer channel, and a flange. Multiple anti-swirl baffles are fixedly welded below the first top plate, and a second top plate is fixedly welded below the anti-swirl baffles. A through-hole is opened in the center of the second top plate, and one end of the buffer channel is fixedly welded to the through-hole. The other end of the buffer channel is fixedly connected to a flange with a central opening.

[0007] Preferably, the first top plate and the second top plate are circular in shape and size.

[0008] Preferably, the anti-rotation baffle is a rectangular baffle, which is vertically welded between the first top plate and the second top plate.

[0009] Preferably, the anti-rotation baffle consists of six baffles, which divide the area of ​​the first top plate into six equal parts. The anti-rotation baffle is positioned between the first top plate and the second top plate, dividing the large space between the first top plate and the second top plate into six smaller channels.

[0010] Preferably, the buffer channel is a hollow, frustum-shaped pipe that is wider at the top and narrower at the bottom. The diameter of the frustum-shaped pipe gradually decreases from top to bottom, and the fluid velocity gradually increases.

[0011] Preferably, the buffer channel is a hollow cylindrical pipe. The cylindrical pipe has a constant cross-section, resulting in a stable fluid flow rate.

[0012] Preferably, the flange is detachably connected to a flange cover without a central hole. During normal transportation and use of the oil tank, a flange gasket is placed between the flange and the flange cover, and the connection is tightened with bolts to ensure the airtightness of the oil tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the anti-swirl baffle between the first and second top plates guides the fluid to flow in a specific direction, avoiding swirling within the oil tank caused by the Earth's rotation, and thus preventing air from entering the oil pump and causing cavitation. Compared with traditional oil pipes, the anti-swirl device is located at the lowest point of the bottom collection trough of the oil tank, which can effectively reduce the minimum oil level, reduce the number of times the pump stops during oil transfer, and reduce the dead oil level.

[0015] In this invention, when fluid flows through the first top plate, the flow is obstructed in the vertical direction because the first top plate does not have holes. As a result, the fluid flows into the channel between the first top plate and the second top plate. This channel is divided into multiple small channels with a certain angle by an anti-swirl baffle. This reduces the fluid velocity at the inlet of each surface, allowing the liquid level to drop evenly and thus preventing the generation of swirl. Attached Figure Description

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1-3 An anti-swirl device for oil tank spillage includes a first top plate 1, an anti-swirl baffle 2, a second top plate 3, a buffer channel 4, and a flange 5. Multiple anti-swirl baffles 2 are fixedly welded below the first top plate 1, and a second top plate 3 is fixedly welded below the anti-swirl baffles 2. A through opening is provided in the center of the second top plate 3, and one end of the buffer channel 4 is fixedly welded to the through opening. The other end of the buffer channel 4 is fixedly connected to the flange 5 with the central opening.

[0025] The first top plate 1 and the second top plate 3 are both circular in shape and size.

[0026] The anti-rotation baffle 2 is a rectangular baffle, which is vertically welded between the first top plate 1 and the second top plate 3.

[0027] The anti-rotation baffle 2 consists of six baffles, which divide the area of ​​the first top plate 1 into six equal parts.

[0028] Buffer channel 4 is a hollow, frustum-shaped pipe that is wider at the top and narrower at the bottom.

[0029] Flange 5 is detachably connected to a flange cover without a central hole.

[0030] Example 2:

[0031] Please see Figure 4-5 This embodiment of the oil tank anti-vortex device is similar to that of Embodiment 1, except that the buffer channel 4 is a hollow cylindrical pipe. By reducing the cross-sectional area of ​​the inlet flow channel and increasing the fluid velocity, the fluid generates greater kinetic energy when passing through the anti-vortex device, thus making it easier to overcome the resistance of the vortex.

[0032] The working principle of this utility model is as follows:

[0033] The bottom of the oil tank is equipped with an inclined collection trough to collect residual material. An anti-spin device is installed at the lowest point of the collection trough. The buffer channel 4 passes through the collection trough. The flange 5 extends out of the bottom of the oil tank and contacts the outside. The flange 5 is connected to a matching valve. When the oil tank is in normal use, the valve on the flange 5 is closed and the flange cover is connected to ensure the airtightness of the tank. When draining oil, after ensuring that the valve is tightly closed, the flange cover on the flange 5 is removed and the external pipeline is connected. After the connection is completed, the valve is opened.

[0034] The first top plate 1 is a complete top plate. When the fluid flows vertically through the first top plate 1, it is obstructed and then flows into the channel between the first top plate 1 and the second top plate 3. This channel is divided into six small channels with certain angles by multiple anti-rotation baffles 2. In this process, the vortex flow generated by the Earth's rotation is disrupted. After the fluid enters the small channels from multiple directions, it flows into the buffer channel 4 and is then collected and recycled by the pipe connected to the flange 5.

[0035] 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.
