Description

Technical Field

[0001] This utility model relates to the field of telescopic bladder technology, and in particular to a fully liquid-contact internal floating oil tank with a wrap-around telescopic bladder device. Background Technology

[0002] In the petrochemical industry, oil storage tanks are key equipment for storing liquid media, and their operation requires effective measures to reduce energy waste and safety hazards caused by media evaporation. Fully wetted internal floating roofs, as an important component within oil storage tanks, move synchronously with the rise and fall of the liquid level. Through close contact with the liquid surface, they significantly reduce the space for media evaporation, thereby achieving energy conservation, emission reduction, and safety protection. However, in practical applications, gaps between components passing through the internal floating roof and the roof itself can easily become channels for media evaporation, affecting the sealing effect of the internal floating roof.

[0003] Existing enclosed telescopic sleeves and related components are prone to poor sealing at their connection points. Because the internal floating roof needs to rise and fall frequently with the liquid level, the relative movement between the internal floating roof and the connecting components can easily lead to loosening or failure of the sealing structure, allowing medium vapor to leak through the gaps. This not only wastes energy but may also cause safety risks. To solve the above problems, this application proposes a fully liquid-contact internal floating roof oil storage tank with an enclosed telescopic sleeve device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fully liquid-contact internal floating roof oil storage tank with a wrap-around telescopic sleeve device. The clamps provided in this device can effectively prevent displacement or detachment during the telescopic sleeve's expansion and contraction. Through the bonding of both ends of the telescopic sleeve and the sealing structure design of the clamps, the sealing performance of the connection parts of related components is greatly improved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fully liquid-contact internal floating tank with a wraparound telescopic sleeve device includes an oil tank, an internal floating plate sealed to it, an opening through the internal floating plate, a waveguide tube fixedly connected to the inner wall of the oil tank, a first ring block fixedly connected to the top of the internal floating plate, a telescopic sleeve body fitted onto the outer wall of the first ring block, a first clamp installed on the outer wall of the telescopic sleeve body, a second ring block fixedly connected to the inner top of the oil tank, the bottom outer wall of the second ring block inserted into the top inner wall of the telescopic sleeve body, a second clamp installed on the outer wall of the telescopic sleeve body, and multiple iron rings evenly spaced on the telescopic sleeve body.

[0006] Preferably, the waveguide and the first ring block are connected, and the waveguide is disposed through the through-hole and the first ring block.

[0007] Preferably, the outer wall of the first ring block is fixedly connected with two first anti-detachment rings, and the first clamp is located between the two first anti-detachment rings.

[0008] Preferably, the outer wall of the second ring block is fixedly connected to two second anti-detachment blocks, and the second clamp is located between the two second anti-detachment blocks.

[0009] Preferably, the telescopic bladder body is fitted onto the outer wall of the first ring block and is bonded and sealed thereto, and the telescopic bladder body is fitted onto the outer wall of the second ring block and is bonded and sealed thereto.

[0010] Preferably, the telescopic bladder body has an installation cavity, and the iron ring is located inside the installation cavity.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The device effectively prevents the fixed components from shifting or falling off during the extension and retraction of the device by means of the clamps, ensuring the reliability of the connection between the sealing device and the upper and lower connecting components, maintaining the overall stability of the device, and thus ensuring the sealing performance.

[0012] 2. This device, through the bonding of both ends of the telescopic bladder sleeve and the sealing structure design with clamps, greatly improves the sealing performance of the connection parts of related components, effectively preventing the leakage of medium vapor through gaps, reducing energy waste, and lowering safety risks.

[0013] In summary, the clamps in this device can effectively prevent displacement or detachment during the extension and retraction of the inner floating roof; the sealing structure design of the adhesive at both ends of the telescopic bladder sleeve and the clamps significantly improves the sealing performance of the connection parts of the relevant components.
