Description

Technical Field

[0001] This invention belongs to the field of safety management and energy conservation and emission reduction technology for atmospheric pressure storage tanks. Specifically, it relates to a floating roof unit for sealing storage tanks, a storage tank sealing floating roof, and an assembly method for the floating roof unit for sealing storage tanks. Background Technology

[0002] In industrial production processes, on-site construction workers often need to store organic liquids such as oil in various storage tanks. At the same time, to prevent environmental pollution and resource waste caused by the evaporation of liquids from the tanks, workers typically install floating roofs inside the tanks. These floating roofs can automatically adjust their position according to changes in the liquid level, thus covering the liquid surface inside the tank and isolating the liquid surface from the external space, ultimately preventing the liquid from evaporating.

[0003] Currently, existing storage tanks are generally constructed in a disc shape, and these floating roofs are usually assembled from multiple roughly fan-shaped floating roof units. Because oil wells produce large quantities of a mixture of natural gas, water, and oil, during oil extraction, operators often need to separate this three-phase mixture to meet production requirements.

[0004] CN213893740U discloses a floating roof structure for oil storage tanks, including a circular frame, a panel, and a venting cylinder. A float is welded inside the circular frame, and sealing tape is glued to the outside of the circular frame. Panels are welded to the bottom and top of the circular frame. An electrostatic conductor is bolted to one end of the top of each panel, and an inspection port is welded to the top of the panel. A venting cylinder is bolted to one side of the inspection port. A structural mesh is bolted to the inside of the venting cylinder, and a transmission rod is sleeved inside the structural mesh. A sealing plate is connected to the top of the transmission rod via a threaded groove, and a float plate is connected to the bottom of the transmission rod via a threaded groove. An anti-rotation block is bolted to the other end of the top of the circular frame. This floating roof structure is made of metal and has the ability to prevent the liquid inside the storage tank from evaporating. Additionally, CN212333531U, CN111268293A, and CN211469465U also disclose corresponding floating roof structures made of metal.

[0005] However, the aforementioned floating roofs generally suffer from the following problems. First, metal floating roofs have poor corrosion resistance, making them prone to failure after prolonged contact with oil. Second, the presence of oil and gas at the top of the metal floating roofs exacerbates corrosion, creating serious safety hazards. Third, due to their modular structure, oil and gas evaporating from the storage tank can easily leak out through the seams, rendering the floating roof unusable.

[0006] CN110077731B discloses a construction method for fabricating fiberglass floating roofs using a spray coating process. The floating roof panel comprises a lower conductive layer, a lower fiberglass layer, a polypropylene honeycomb layer, an upper fiberglass layer, and an upper flame-retardant conductive layer. The main tool of this invention is a fiberglass spray gun. The spray gun uses a high-speed motor to pull out continuous glass fibers, which are then quickly chopped short using scissors. A high-pressure pump delivers resin, and the resin, fibers, and a suitable amount of curing liquid are mixed and sprayed at high speed to achieve rapid construction. This invention uses continuous fiberglass to replace chopped strand mat and fiberglass cloth used in hand lay-up methods. Continuous fiberglass is manufactured from glass through high-temperature melting, drawing, winding, and weaving processes. Its main components are silicon dioxide, aluminum oxide, calcium oxide, boron oxide, magnesium oxide, and sodium oxide.

[0007] The floating roof is made of composite materials in a single piece and has high strength. However, the following problems still exist. First, if the device is damaged or leaks during storage, it is impossible to conduct an accurate inspection, which significantly increases the cost of storing the oil. Second, the floating roof has a complex manufacturing process and requires on-site spraying with vinyl ester resin. On the one hand, because vinyl ester resin contains a large amount of styrene, the protection requirements for spraying personnel are high, thereby increasing manufacturing costs and reducing construction efficiency. On the other hand, because a large amount of resin spraying work needs to be carried out in a confined space, there are significant safety hazards.

[0008] Therefore, it is desirable in the art to provide a tank sealing floating roof to solve the above problems. Summary of the Invention

[0009] To address the technical problems described above, this invention aims to provide a floating roof unit for sealing storage tanks. The floating roof unit of this invention not only improves the sealing effect of the floating roof but also extends its service life and the reliability of the seal.

[0012] In a preferred embodiment, the outer sealing plate and the clamping plate are further covered with a first sealing layer and a second sealing layer, respectively, and the first sealing layer and the second sealing layer are configured to extend out of the outer sealing plate and the clamping plate to form a connecting portion.

[0013] In a preferred embodiment, the first sealing layer is made of nonwoven fabric and the second sealing layer is made of chopped strand mat.

[0014] In a preferred embodiment, a first step portion consisting of multiple steps of different sizes is provided on the central frame, and a second step portion corresponding to the multiple steps is provided on the outer sealing plate and the clamping plate, and the outer sealing plate and the clamping plate are connected to the central frame through the first step portion and the second step portion.

[0015] In a preferred embodiment, a surface plate is further provided on the outer end face of the sealing assembly away from the central frame.

[0016] In a preferred embodiment, the surface plate is provided with a third sealing layer, which is made of fiberglass material.

[0017] In a preferred embodiment, two sealing components are provided, which are symmetrically arranged on the upper and lower sides of the central frame.

[0018] In a preferred embodiment, an adhesive component capable of being fixedly connected to the central frame is further provided on the central frame.

[0019] In a preferred embodiment, a through groove is provided on the side wall of the central frame, and the adhesive is configured to extend longitudinally into the through groove to form a connection with the central frame.

[0020] The lateral width of the adhesive is set to be greater than the lateral width of the through groove, so that the adhesive has an extension that extends laterally out of the through groove after it is inserted into the through groove.

[0021] In a preferred embodiment, the adhesive includes an upper plate and a lower plate, and a support disposed between the upper plate and the lower plate.

[0022] At least one casting hole is provided on the upper plate and the lower plate respectively, which penetrates the upper plate and the lower plate in a vertical direction.

[0023] According to a second aspect of the present invention, a floating roof for sealing a storage tank is provided, which is composed of a plurality of the aforementioned floating roof units for sealing storage tanks.

[0024] According to a third aspect of the present invention, a method for assembling a floating roof for sealing a storage tank is provided, comprising a plurality of the aforementioned floating roof units for sealing the storage tank, the method comprising:

[0025] Step 1: Build a support frame inside the storage tank, lay a flat plate on the support frame to form an overlapping platform, and lay a PET release film on the overlapping platform;

[0026] Step 2: Arrange any two of the aforementioned tank sealing floating roof units on the overlapping platform, leaving an appropriate gap between the sealing floating roof units so that the connecting parts on the first sealing layer and the second sealing layer of the two sealing floating roof units are connected accordingly.

[0027] Step 3: Apply resin material to the connecting part for impregnation, and connect the connecting part located below the central frame by overlapping after impregnation. Then inject adhesive into the overlapping connecting part.

[0029] Step 5: Connect the support body and the upper plate body to the lower plate body in sequence, and then inject adhesive into the pouring hole on the upper plate body;

[0030] Step Six: After the multi-layered connecting parts located above the central frame are soaked, they are connected by overlapping. Then, adhesive is injected into the overlapping connecting parts, and the surface plate is installed on the sealing assembly to realize the connection of the two sealing floating units.

[0031] Step 7: Repeat steps 2 through 6 until a sufficient number of sealed floating roof units are connected together to form a complete sealed floating roof.

Furthermore, this invention can suppress oil evaporation at the source, thereby effectively reducing oil loss. Additionally, due to the characteristics of the non-metallic material (fiberglass), the floating roof unit 100 used for tank sealing can be stored in the tank for a long time without being corroded by the oil inside, thus improving the reliability and service life of the floating roof unit. Moreover, this invention can effectively and accurately detect whether there is leakage at the joints, thereby greatly improving the safety of the floating roof unit used for tank sealing and further ensuring the safety of oil storage in the tank.

[0046] 100 Floating roof units for tank sealing Detailed Implementation

[0047] To make the technical solutions and advantages of the present invention clearer, exemplary embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. Furthermore, the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0048] The invention will now be described with reference to the accompanying drawings.

[0049] Figure 1A schematic diagram of a floating roof unit 100 for sealing a storage tank according to an embodiment of the present invention is shown.

[0050] like Figure 1 As shown, the floating roof unit 100 for sealing storage tanks according to the present invention includes a central frame 10. The central frame 10 is square in shape. A plurality of through holes 12 extending vertically through the central frame 10 are provided therein. Preferably, the plurality of through holes 12 can be circular, square or other irregular shapes, for example.

[0051] In one embodiment, the plurality of through holes 12 are evenly arranged on the central frame 10, thereby forming a through hole array on the central frame 10. Preferably, the through hole array is, for example, as shown below. Figure 1 The 4x4 array shown.

[0052] Figure 2 for Figure 1 The diagram shown is an anatomical representation of the floating roof unit 100 used for sealing the storage tank.

[0053] According to the present invention, such as Figure 2 As shown, the tank sealing floating roof unit 100 also includes a filler 20. The filler 20 can extend into the through hole 12 and can seal the through hole 12 to achieve a seal on both sides of the central frame 10. Details are described below.

[0054] In one embodiment, the filler 20 has a shape adapted to the central frame 10, and the filler 20 is configured to correspond one-to-one with the plurality of through holes 12 of the central frame 10. Therefore, the filler 20 is configured to extend into each of the through holes 12, thereby closing each of the through holes 12.

[0055] According to one embodiment of the present invention, when the filler 20 seals the through hole 12, the filler 20 can block the communication between the upper and lower sides of the through hole 12. In other words, when the central frame 10 covers the oil surface of the storage tank (not shown), it can isolate the oil from the air, further preventing the oil vapor in the oil from evaporating and causing loss.

[0056] In a preferred embodiment, both the central frame 10 and the filler 20 are made of polypropylene. Compared to existing floating roof structures made of metal, the floating roof structure made of polypropylene in this invention has excellent corrosion resistance.

[0057] Specifically, due to the characteristics of non-metallic materials, the tank sealing floating roof unit 100 can be stored in the tank for a long time without being corroded by the oil in the tank, which helps to improve the reliability and service life of the tank sealing floating roof unit 100.

[0058] Furthermore, as is generally known, polypropylene has low volatility, thus significantly reducing the protective requirements for on-site personnel when installing the floating roof unit 100 for tank sealing. This results in a substantial reduction in operating costs for the floating roof unit 100 and a significant improvement in operational efficiency.

[0059] In one specific embodiment, the central frame 10 is integrally injection molded from polypropylene material. This allows the central frame 10 to have higher strength and better density, thereby improving its reliability and sealing performance.

[0060] In one specific embodiment, the filler 20 is manufactured using a foaming process. It is readily understood that this manufacturing process allows for sufficient control over the size and shape of the filler 20. Therefore, the floating roof unit 100 for tank sealing can adjust the size and shape of the filler 20 according to actual needs to achieve a more complete fit with the inner surface of the central frame 10, thereby significantly improving the connection between the filler 20 and the central frame 10, and further enhancing the sealing performance of the floating roof unit 100 for tank sealing.

[0061] According to the present invention, such as Figure 2 As shown, the floating roof unit 100 for sealing the storage tank also includes a sealing assembly 30 disposed on the central frame 10. The structure and layout of the sealing assembly 30 will be described in detail below.

[0062] In one embodiment, the sealing assembly 30 includes an outer sealing plate 32 and at least one clamping plate 34. Two outer sealing plates 32 are provided, and the two outer sealing plates 32 are arranged opposite to each other. Preferably, the clamping plate 34 is disposed between the two outer sealing plates 32, thereby enabling the two outer sealing plates 32 to be connected together, further improving the sealing performance of the floating roof unit 100 used for sealing the storage tank.

[0063] In a preferred embodiment, the outer sealing plate 32 and the clamping plate 34 are injection molded from polypropylene. Compared to existing floating roof structures made of metal, the floating roof structure made of polypropylene in this invention has excellent corrosion resistance.

[0064] Specifically, due to the characteristics of non-metallic materials, the tank sealing floating roof unit 100 can be stored in the tank for a long time without being corroded by the oil in the tank, which helps to improve the reliability and service life of the tank sealing floating roof unit 100.

[0065] In one embodiment, both the outer sealing plate 32 and the clamping plate 34 are constructed as flat plates adapted to fit the central frame 10, thereby enabling more complete and comprehensive coverage of the central frame 10. Thus, the combined action of the outer sealing plate 32 and the clamping plate 34 effectively assists in sealing the central frame 10, thereby improving the sealing performance of the floating roof unit 100 used for tank sealing.

[0066] In one embodiment, a first step portion 17 is provided on the central frame 10. Preferably, the first step portion 17 is composed of a plurality of steps 175 of different sizes, so that it can engage with a second step portion 37 (described below) to improve the sealing performance of the floating roof unit 100 for sealing the tank.

[0067] In one embodiment, a second step portion 37 is provided on the outer sealing plate 32 and the clamping plate 34 respectively. The second step portion 37 corresponds one-to-one with the plurality of steps 175. Therefore, after installation, the floating roof unit 100 for sealing the storage tank can provide a more robust sealing environment through the engagement of the second step portion 37 of the outer sealing plate 32 and the clamping plate 34 with the first step portion 17 of the central frame 10, thereby effectively containing the oil and gas inside the storage tank.

[0068] Furthermore, the central frame 10 can form a stable connection with the second step 37 of the outer sealing plate 32 and the second step 37 of the clamping plate 34 through the first step 17, thereby ensuring the reliability of the tank sealing floating unit 100 and further extending the service life of the tank sealing floating unit 100.

[0069] According to one embodiment of the present invention, after the first step portion 17 and the second step portion 37 form a stable connection relationship, the outer sealing plate 32 and the clamping plate 34 can be stably installed on the outside of the central frame 10, thereby fully and completely covering and sealing the connection position between the central frame 10 and the outer sealing plate 32 and the clamping plate 34.

[0070] In other words, the first step 17 of the central frame 10, the second step 37 of the outer sealing plate 32, and the second step 37 of the clamping plate 34 can effectively reduce the impact of small connection gaps in the installation of the floating roof unit 100 for sealing the storage tank on the sealing performance of the central frame 10, thereby making it difficult for the oil and gas volatilized in the storage tank to overflow from the joint, and further improving the sealing performance of the floating roof unit 100 for sealing the storage tank.

[0071] According to the present invention, such as Figure 2 As shown, the floating roof unit 100 for sealing the storage tank also includes a first sealing layer 325 disposed on the outer sealing plate 32. Preferably, the first sealing layer 325 is installed on the outer sealing plate 32 in a covering manner.

[0072] According to the present invention, such as Figure 2 As shown, the floating roof unit 100 for sealing the storage tank also includes a second sealing layer 345 disposed on the clamping plate 34. Preferably, the second sealing layer 345 is installed on the clamping plate 34 in a covering manner.

[0073] Therefore, the combined action of the first sealing layer 325 and the second sealing layer 345 can effectively assist in sealing the central frame 10, thereby improving the sealing performance of the floating roof unit 100 used for tank sealing.

[0074] In one embodiment of the present invention, the first sealing layer 325 and the second sealing layer 345 can effectively protect the outer sealing plate 32 and the clamping plate 34 respectively, thereby enabling the outer sealing plate 32 and the clamping plate 34 to have a certain degree of corrosion resistance, thereby ensuring that the floating plate unit 100 used for sealing the storage tank can be placed in the storage tank for a long time, so as to effectively isolate the connection between the liquid surface of the storage tank and the external space, and further suppress the possibility of liquid evaporation in the storage tank.

[0075] In a preferred embodiment, the first sealing layer 325 is made of non-woven fabric. As is generally known, this material not only has good sealing performance but also strengthens the seal. Furthermore, this material has strong insulating properties; therefore, the floating roof unit 100 used for sealing the storage tank can effectively reduce the risk of oil combustion and explosion, further improving the safety of the stored oil. In addition, it is worth noting that this material is inexpensive on the market, thus effectively reducing the production cost of the floating roof unit 100 used for sealing the storage tank.

[0076] In a preferred embodiment, the second sealing layer is made of chopped strand mat material. As is known from common knowledge, this material not only has good sealing performance but also strengthens adhesion, thereby effectively improving the sealing performance of the floating roof unit 100 used for tank sealing.

[0077] In one embodiment, since both the first sealing layer 325 and the second sealing layer 345 are made of the materials described above, the connection between the first sealing layer 325 and the second sealing layer 345 and the interconnection between the multiple second sealing layers 345 have better density and stronger stability, further improving the sealing performance of the floating roof unit 100 used for tank sealing.

[0078] According to the present invention, such as Figure 2 As shown, the first sealing layer 325 and the second sealing layer 345 are respectively configured to extend out of the outer sealing plate 32 and the clamping plate 34, thereby forming a connecting portion 35 extending out of the central frame 10. The connecting portion 35 enables the connection between multiple tank sealing floating roof units 100. This connection process will be described in detail below.

[0079] In one embodiment, such as Figure 2 As shown, a surface plate 40 is further provided on the outer end face 36 of the sealing assembly 30 away from the central frame 10. A third sealing layer 45 is provided on the surface plate 40. Preferably, the third sealing layer 45 can be made of fiberglass, for example. This material not only has good corrosion resistance and insulation properties, but also high strength and rigidity.

[0080] Therefore, on the one hand, the third sealing layer 45 can effectively protect the central frame 10 and the sealing assembly 30. On the other hand, the third sealing layer 45 can support the central frame 10 and the sealing assembly 30, thereby preventing the central frame 10 and the sealing assembly 30 from deforming during long-term use, thus ensuring that the central frame 10 and the sealing assembly 30 can always maintain a stable working state, further improving the sealing performance of the tank sealing floating roof unit 100.

[0081] In one embodiment, the third sealing layer 45 is made of fiberglass. Preferably, the thickness of the fiberglass is 3.5 mm. Fiberglass, or fiber-reinforced plastic, generally refers to reinforced plastics that use glass fibers to reinforce unsaturated polyester, epoxy resin, and phenolic resin matrices, with glass fibers or their products as reinforcing materials. This is different from tempered glass. This is well known to those skilled in the art and therefore will not be elaborated further.

[0082] In one embodiment, reinforcing ribs (not shown) are also provided on the inner wall of the through hole 12. It is readily understood that the reinforcing ribs further enhance the strength of the central frame 10, thereby reducing the risk of damage or deformation of the central frame 10 during prolonged use. Preferably, the reinforcing ribs also serve as the skeleton structure of the entire tank sealing floating roof unit 100, thereby ensuring that the central frame 10 remains in a stable working state within the tank.

[0083] In a preferred embodiment, two sealing components 30 are provided, and the two sealing components 30 are symmetrically arranged on the upper and lower sides of the central frame 10. This arrangement effectively improves the overall strength and sealing performance of the floating roof unit 100 for sealing the storage tank, thereby effectively preventing oil and gas from leaking out of the joints. Furthermore, it helps to stabilize the center of the floating roof unit 100 within the central frame 10, thereby improving the overall stability of the sealing floating roof unit 100.

[0084] Figure 3 for Figure 1 A partial schematic diagram of the central frame 10 of the floating roof unit 100 for sealing storage tanks.

[0085] According to the present invention, such as Figure 3 As shown, the floating roof unit 100 for sealing the storage tank also includes a through groove 18. The through groove 18 is provided on the side walls 11 around the central frame 10, thereby allowing the adhesive member 50 (described below) to extend into it to form a stable connection with the central frame 10.

[0086] According to the present invention, such as Figure 3 As shown, the floating roof unit 100 for sealing the storage tank also includes an adhesive member 50. The adhesive member 50 is configured to extend longitudinally into the through groove 18, thereby forming a stable connection with the central frame 10.

[0087] In one embodiment of the invention, the lateral width of the adhesive member 50 is set to be greater than the lateral width of the through groove 18. Therefore, when the adhesive member 50 extends into the through groove 18, it can form an extension 52 extending laterally out of the through groove 18. Thus, the extension 52 allows the adhesive member 50 to extend into the through groove 18 of another floating roof unit 100 for tank sealing, thereby connecting any two floating roof units 100 for tank sealing together.

[0088] According to the present invention, such as Figure 3As shown, the adhesive component 50 includes an upper plate 54, a lower plate 56, and a support 58. The support 58 is disposed between the upper plate 54 and the lower plate 56. In one embodiment, the upper plate 54, the lower plate 56, and the support 58 are all connected together in a detachable manner. This allows the floating roof unit 100 for tank sealing to be installed and disassembled more quickly, thereby effectively improving work efficiency.

[0089] In one embodiment, at least one casting hole 545 is provided on the upper plate 54 and the lower plate 56 respectively, penetrating vertically through the upper plate 54 and the lower plate 56. It is readily understood that during subsequent installation work, adhesive can be injected into the floating roof unit 100 for tank sealing through the casting hole 545, thereby completing the bonding work of the entire floating roof unit 100 for tank sealing.

[0090] It is easy to understand that the aforementioned injection of adhesive can effectively seal any small connection gaps that exist during the installation of the floating roof unit 100 used for sealing the storage tank, thereby reducing the impact of these small connection gaps on the sealing performance of the central frame 10. In this way, oil vapors volatilized from the oil inside the storage tank are less likely to escape from the connection gaps, further improving the sealing performance of the floating roof unit 100 used for sealing the storage tank.

[0091] Figure 4 for Figure 1 The diagram shows the assembly of the floating roof unit 100 used for sealing the storage tank.

[0092] The following is based on Figure 4 The content shown in Figure a describes the assembly operation of the floating roof unit 100 used for sealing the storage tank:

[0093] First, the operator needs to place any two of the aforementioned tank sealing floating roof units 100 together, leaving an appropriate gap 60 between the sealing floating roof units 100, so that the connecting portions 35 on the first sealing layer 325 and the second sealing layer 345 of the two sealing floating roof units 100 are connected accordingly.

[0094] Then, resin material is applied to the connecting part 35 for impregnation, and the connecting part 35 located below the central frame 10 is connected by overlapping layers after impregnation.

[0095] Finally, adhesive is injected into the overlapped joint 35 to reinforce the connection. Preferably, the adhesive may be, for example, epoxy resin.

[0096] The following is based on Figure 4 The content shown in b describes the assembly operation of the floating roof unit 100 used for tank sealing:

[0097] First, after the connecting part 35 below the central frame 10 is overlapped, the operator can insert the lower plate 56 of the adhesive 50 into the gap 60, so that the lower plate 56 is above the overlapped connecting part 35, and at the same time, the two ends of the lower plate 56 are respectively inserted into the through slots 18 of the two floating units 100.

[0098] Then, after the lower plate 54 is connected, the operator can inject adhesive into the lower connecting part 35 through the pouring hole 545 on the lower plate 56 to further strengthen the connection between the connecting parts 35.

[0099] The following is based on Figure 4 The content shown in Figure c describes the assembly operation of the floating roof unit 100 used for tank sealing:

[0100] After the adhesive in the pouring hole 545 of the lower plate 56 is filled, the operator can install the support 58 and the upper plate 54 onto the lower plate 56, so that both ends of the upper plate 54 extend into the through slots 18 of the two floating plate units 100 and connect with the connecting part 35 above the central frame 10. Then, adhesive is injected into the pouring hole 545 on the upper plate 54.

[0101] The following is based on Figure 4 The content shown in d describes the assembly operation of the floating roof unit 100 used for tank sealing:

[0102] Once the adhesive in the pouring hole 545 on the upper plate 54 is filled, the operator can then wet the connecting part 35 above the central frame 10 and connect them by overlapping. Adhesive is then injected into the overlapping connecting part 35 to strengthen the connection.

[0103] The following is based on Figure 4 The content shown in e describes the assembly operation of the floating roof unit 100 used for tank sealing:

[0104] Once the connecting part 35 above the central frame 10 is connected, the operator can install the surface plate 40 on the sealing assembly 30, thereby completing the connection between the two floating units 100.

[0105] By repeating this process, a sufficient number of floating roof units 100 can be spliced ​​together to achieve the connection of the entire floating roof used for tank sealing.

[0106] Compared with existing splicing methods, the floating roof unit 100 for tank sealing of the present invention has better density and connection stability after splicing, thereby improving the sealing performance and reliability of the entire floating roof and effectively preventing oil and gas from evaporating from the connection part of the floating roof unit 100.

[0107] It is worth noting that, such as Figure 4 As shown in Figure e, after the floating roof unit 100 for sealing the storage tank is installed, the gap 60 is transformed into a through gap 61 on both sides of the support body 58 under the action of the support body 58. According to an embodiment of the present invention, the main function of the gap 61 is to detect the sealing performance of the joints of the floating roof unit 100 for sealing the storage tank.

[0108] Specifically, after the floating roof unit 100 for sealing the storage tank is installed, the gap 61 can be pressurized. If the floating roof unit 100 can maintain pressure, it indicates that there is no leakage at the joint of the floating roof unit 100 for sealing the storage tank; if the floating roof unit 100 cannot maintain pressure, it indicates that there is leakage at the joint of the floating roof unit 100 for sealing the storage tank. In this case, soap bubbles need to be applied to the joint, and the specific leakage gap needs to be accurately detected to ensure the sealing performance of the floating roof unit 100 for sealing the storage tank.

[0109] Compared to floating roof structures made of composite materials in one piece, this invention can effectively and accurately detect whether there is leakage at the joints, thereby greatly improving the safety of the floating roof unit 100 used for sealing storage tanks and further ensuring the safety of oil storage in storage tanks.

[0110] It should be noted that the central frame 10 of the floating roof unit 100 for sealing storage tanks of the present invention can also be constructed as a semi-circle. In this way, during the sealing operation of a circular tank, the operator can install this semi-circular floating roof unit 100 on the outer side of the entire floating roof after the floating roof is assembled, so that the straight surface of the floating roof unit 100 is normally in contact with the square floating roof unit 100, while the arc surface of the semi-circular floating roof unit 100 abuts against the inner wall of the circular tank. Through this arrangement, the floating roof unit 100 for sealing storage tanks of the present invention can also be applied to circular tanks, thereby improving the applicability of the floating roof unit 100 for sealing storage tanks of the present invention.

[0111] The following is a brief description of the operation of the floating roof unit 100 for sealing storage tanks according to the present invention.

[0112] The floating roof unit 100 for sealing storage tanks of the present invention is used to splice together to form a complete floating roof, thereby enabling the storage tank to be sealed.

[0113] During the assembly process, workers first need to build a support frame (not shown) inside the storage tank and then lay a flat plate (not shown) on the support frame to form an overlapping platform. After the overlapping platform is laid, workers can then lay a PET release film on the platform.

[0114] Subsequently, the operator needs to arrange any two of the aforementioned tank sealing floating roof units 100 on the overlapping platform, and leave an appropriate gap 60 between the sealing floating roof units so that the connecting parts 35 on the first sealing layer 325 and the second sealing layer 345 of the two sealing floating roof units are connected accordingly.

[0115] At this point, the operator can apply resin material to the connecting part 35 for impregnation, and connect the multi-layer connecting parts 35 located below the central frame 10 by overlapping after impregnation, and then inject adhesive into the overlapping connecting parts.

[0116] After the adhesive is injected, the operator can insert the lower plate 56 into the through groove 18, so that the lower plate 56 is located at the upper end of the overlapping connection part 35, and then inject adhesive into the pouring hole 545 on the lower plate 56.

[0117] After the adhesive in the pouring hole 545 on the lower plate 56 is filled, the operator can connect the support body 58 and the upper plate 54 to the lower plate 56 in sequence, and then inject adhesive into the pouring hole 545 on the upper plate 54 until the pouring hole 545 is filled.

[0118] Subsequently, the operators need to connect the multi-layered connecting parts, after the connecting part 35 above the central frame 10 has been soaked, by overlapping them and injecting adhesive into the overlapped connecting parts. Finally, the surface plate 40 is installed on the sealing assembly 30, thereby completing the connection between the two floating table units 100.

[0119] By repeating this process, a sufficient number of floating roof units 100 can be spliced ​​together to achieve the connection of the entire floating roof used for tank sealing.

[0120] This invention provides a floating roof unit for sealing storage tanks, which can suppress oil evaporation at the source, thereby effectively reducing oil loss. Furthermore, due to the characteristics of its non-metallic material (fiberglass), the floating roof unit 100 can be stored in the storage tank for extended periods without being corroded by the oil inside, thus improving its reliability and service life. In addition, this invention can effectively and accurately detect leaks at the joints, greatly improving the safety of the floating roof unit 100 for sealing storage tanks and further ensuring the safety of oil storage within the tank.

[0121] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
