Description

Technical Field

[0001] This utility model relates to the field of chemical storage tank technology, and in particular to an internal floating roof structure for chemical storage tanks. Background Technology

[0002] According to the internal floating roof structure for chemical storage tanks disclosed in Chinese Patent No. CN221606674U, the problem of the internal floating roof being prone to rupture due to the continuous increase of air pressure under it during the oil injection process is solved. It includes an internal floating roof body, a sealing gasket fixedly installed on the outer side of the internal floating roof body, a grid frame fixedly installed on the bottom of the internal floating roof body, and a buffer mechanism installed on the internal floating roof body.

[0003] The aforementioned comparative documents and existing technologies have the following technical problems: aging or damage to existing sealing materials can lead to the evaporation and leakage of media such as oil, which not only causes material loss but may also bring safety hazards and environmental pollution; uneven settlement of the tank foundation can cause the tank to tilt, causing the floating roof guide column to tilt and get stuck, which requires timely detection of whether the floating roof is tilted; and when the internal liquid level drops, the floating roof will also drop, and too rapid a drop can cause damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an internal floating roof structure for chemical storage tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an internal floating roof structure for chemical storage tanks, comprising a floating roof cover plate, a sealing gasket on the outer side of the floating roof cover plate, a manhole at the top of the floating roof cover plate, an anti-rotation guide post on one side of the manhole, a buffer assembly at the bottom of the floating roof cover plate, a guide bracket at the center of the bottom end of the floating roof cover plate, a connecting plate on the outer side of the guide bracket, a main beam at the outer end of the guide bracket, a secondary beam on the outer side of the main beam, a movable floating pipe on the outer side of the secondary beam, and an outer perimeter floating pipe on the outer side of the connecting plate.

[0006] Preferably, a sealing ring is provided on the outer side of the sealing gasket, the sealing gasket is made of elastic material, and the width of the sealing ring is higher than the top and bottom ends of the sealing gasket.

[0007] Preferably, a spirit level is provided on the inner side of the top of the anti-rotation guide post, and the anti-rotation guide post penetrates the floating roof cover plate.

[0008] Preferably, the buffer assembly includes a guide post, a buffer post at the bottom of the guide post, a spring on the outside of the buffer post, a rubber pad at the bottom of the buffer post, and a buffer block at the top of the guide post.

[0009] Preferably, the buffer block and the floating roof cover plate, as well as the buffer block and the guide post, are connected by welding, and the bottom of the rubber pad and the top of the buffer block are rounded.

[0010] Preferably, the inner side of the guide bracket is provided with a connecting column, and the connecting column is connected to the main beam and the main beam and the secondary beam by welding. The secondary beam has a biomimetic hexagonal structure.

[0011] Preferably, the movable float tube has sliders at both ends, a locking knob on the outside of the slider, and the outer float tube is located between the connecting plate and the sealing gasket.

[0012] Beneficial effects

[0013] In this invention, a sealing gasket and a sealing ring are used in combination. The sealing gasket is made of elastic material and can fit tightly against the contact surface of the floating roof to form a high-quality layer seal. The sealing ring is located on the periphery of the sealing gasket and further enhances the sealing effect through its unique structure and material properties.

[0014] This invention employs an anti-rotation guide post, which not only has an anti-rotation function but also a bubble level, allowing for timely detection of whether the float is tilting.

[0015] In this invention, a buffer component is used. The buffer component can cushion the bottom of the tank when the floating roof descends, and the rubber pad can better cushion the descent of the tank bottom, thus preventing damage to the floating roof and the tank during the descent process.

[0016] In this invention, a movable floating tube, an outer floating tube, and a biomimetic hexagonal structure are adopted. The biomimetic hexagonal structure design makes the inner floating plate more uniformly stressed in the storage tank, which can better resist liquid fluctuations and external impacts, reduce the risk of deformation and damage, and the movable floating tube can better adjust the internal buoyancy, so that the floating tube can be evenly arranged and evenly stressed for the floating plate.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4This utility model provides an internal floating roof structure for chemical storage tanks, including a floating roof cover plate 1, a sealing gasket 2 on the outer side of the floating roof cover plate 1, and a sealing ring 201 on the outer side of the sealing gasket 2.

A manhole 3 is provided at the top of the floating roof cover plate 1, and an anti-rotation guide post 4 is provided on one side of the manhole 3. A spirit level 401 is provided on the inner side of the top of the anti-rotation guide post 4, and the anti-rotation guide post 4 penetrates through the floating roof cover plate 1. A buffer assembly 5 is provided at the bottom of the cover plate 1. The buffer assembly 5 includes a guide post 501, a buffer post 502 at the bottom of the guide post 501, a spring 503 on the outside of the buffer post 502, a rubber pad 504 at the bottom of the buffer post 502, and a buffer block 505 at the top of the guide post 501. The buffer block 505 is welded to the floating roof cover plate 1 and to the guide post 501. The bottom of the rubber pad 504 and the top of the buffer block 505 are both... The bottom center of the floating roof cover 1 is equipped with a guide bracket 6 with rounded corners. A connecting plate 7 is provided on the outside of the guide bracket 6.

[0032] 3. The use of buffer component 5 ensures that the floating roof and storage tank are not damaged during the descent of the floating roof.

[0033] 4. By adopting the structure of movable float tube 10, outer float tube 11 and biomimetic hexagon, the floating plate is subjected to more uniform force in the storage tank, which can better resist liquid fluctuations and external impacts, reduce the risk of deformation and damage, and the internal float tubes can be adjusted so that the float tubes can be evenly arranged and evenly stressed on the floating plate.
