A new type of fully welded stainless steel internal floating roof floating plate

Abstract

The present invention relates to the technical field of floating roofs and floating plates within storage tanks, and more specifically to a novel fully welded stainless steel internal floating roof and floating plate, comprising: an upper skin and a lower skin, both of which are a complete piece of steel plate, with only the edges fully welded to the upper skin mounting edges and the lower skin mounting edges on the edge plates. This eliminates the need for a pontoon in the prior art, avoids welding and the use of sealing gaskets between pontoons in the prior art, and thus eliminates the need for excessive sealing gaskets and bolts to achieve installation in place. Furthermore, when sending and receiving oil inside the storage tank, the upper skin and the lower skin are integrated with the longitudinal beams, the transverse beams and the edge plates, so that when the floating plate swings, they will swing simultaneously, and the problem of gap separation between adjacent pontoons in the prior art will not occur, thereby improving the sealing effect.

Description

Technical Field

[0001] The invention relates to the technical field of internal floating roof and floating plate of storage tanks, and more particularly to a novel fully welded stainless steel internal floating roof and floating plate. Background Art

[0002] In order to improve the environment and reduce VOCs emissions, the country now requires large storage tanks to be installed with floating plates;

[0003] Among the existing internal floating roof floating plates, the mainstream floating plates are now spliced ​​stainless steel floating plates;

[0004] Spliced ​​stainless steel floating platform; composed of several pontoons, divided into two types: beam structure and beamless structure; the pontoons and beams, as well as the pontoons and pontoons are connected by bolts, which has the advantages of easy maintenance and fast installation, and has achieved relatively good results;

[0005] However, based on the promotion and application in recent years, some problems have also been discovered;

[0006] The size of the stainless steel spliced ​​pontoon is generally about 3m*0.55m, and the thickness including the installation edge is generally 150-180mm. The diameter of the general internal floating roof tank is between 11m-45m, with a diameter of 5000m. 3 Take the storage tank as an example, 5000m 3 The diameter of the storage tank is generally 21m, the edge gap is 0.2m, the diameter of the floating plate is 20.6m, the width of the pontoon is 0.55m, the pontoons are arranged in 38 rows, with a maximum of 7 pontoons in each row, and the number of pontoons in the entire floating plate is about 200;

[0007] The spliced ​​buoy is made of buoy boxes. The spliced ​​gaps are mainly sealed by gaskets and sealants. 3 Taking a storage tank as an example, there are about 200 pontoons on the entire floating platform. The length of the sealing gasket of each pontoon is about 5.3 meters. The length of the sealing gasket of the entire floating platform is about 1,100 meters. The number of sealing bolts per meter of sealing gasket is 6-10, and the number of sealing bolts for the entire storage tank is 7,000-8,000. It is difficult to ensure that all sealing gaskets and sealing bolts are installed in place during on-site construction. In addition, each pontoon has four corners, and sealing bolts cannot be installed at the corners. They are weak points in sealing. There are hundreds of weak points in sealing on the entire floating platform, which makes it difficult to ensure the sealing effect of the floating platform.

[0008] 1) Due to the excessive number of sealing pads and sealing bolts, it is impossible to ensure that all of them are installed in place. When the float plate is new, the sealing effect is good due to the sealing effect of the sealant. However, when receiving and sending oil, the swing of the float plate causes the sealant to fail, and the sealing effect drops sharply;

[0009] 2) Aging of the gasket. Since the gasket is made of rubber foam, the medium stored in the tank often contains various components, which shortens the life of the gasket. In addition, the up and down swing of the float in the oil causes the gasket to be repeatedly squeezed, causing the gasket to fail quickly, thereby causing the seal to fail. In addition, the pontoon is used more frequently, and gaskets are used between each pontoon. Therefore, when the gasket ages, it is inconvenient to repair and the repair cost is too high.

[0010] In summary, the present application proposes a new type of fully welded stainless steel internal floating roof floating plate to improve any of the technical problems mentioned above. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] In order to improve the environment and reduce VOCs emissions, the country now requires large storage tanks to be installed with floating plates;

[0037] Among the existing internal floating roof floating plates, the mainstream floating plates are now spliced ​​stainless steel floating plates;

[0038] Spliced ​​stainless steel floating platform; composed of several pontoons, divided into two types: beam structure and beamless structure; the pontoons and beams, as well as the pontoons and pontoons are connected by bolts, which has the advantages of easy maintenance and fast installation, and has achieved relatively good results;

[0039] However, based on the promotion and application in recent years, some problems have also been discovered;

[0040] The size of the stainless steel spliced ​​pontoon is generally about 3m*0.55m, and the thickness including the installation edge is generally 150-180mm. The diameter of the general internal floating roof tank is between 11m-45m, with a diameter of 5000m. 3 Take the storage tank as an example, 5000m 3 The diameter of the storage tank is generally 21m, the edge gap is 0.2m, the diameter of the floating plate is 20.6m, the width of the pontoon is 0.55m, the pontoons are arranged in 38 rows, with a maximum of 7 pontoons in each row, and the number of pontoons in the entire floating plate is about 200;

[0041] The spliced ​​buoy is made of buoy boxes. The spliced ​​gaps are mainly sealed by gaskets and sealants. 3 Taking a storage tank as an example, there are about 200 pontoons on the entire floating platform. The length of the sealing gasket of each pontoon is about 5.3 meters. The length of the sealing gasket of the entire floating platform is about 1,100 meters. The number of sealing bolts per meter of sealing gasket is 6-10, and the number of sealing bolts for the entire storage tank is 7,000-8,000. It is difficult to ensure that all sealing gaskets and sealing bolts are installed in place during on-site construction. In addition, each pontoon has four corners, and sealing bolts cannot be installed at the corners. They are weak points in sealing. There are hundreds of weak points in sealing on the entire floating platform, which makes it difficult to ensure the sealing effect of the floating platform.

[0042] 1) Due to the excessive number of sealing pads and sealing bolts, it is impossible to ensure that all of them are installed in place. When the float plate is new, the sealing effect is good due to the sealing effect of the sealant. However, when receiving and sending oil, the swing of the float plate causes the sealant to fail, and the sealing effect drops sharply;

[0043] 2) Aging of the gasket. Since the gasket is made of rubber foam, the medium stored in the tank often contains various components, which shortens the life of the gasket. In addition, the up and down swing of the float in the oil causes the gasket to be repeatedly squeezed, causing the gasket to fail quickly, thereby causing the seal to fail. In addition, the pontoon is used more frequently, and gaskets are used between each pontoon. Therefore, when the gasket ages, it is inconvenient to repair and the repair cost is too high.

The middle portion of the blades 41 is hollow. The central leg 22 passes through the inside of the blade 41 and is connected to the connection between the cross beam 15 and the longitudinal beam 14. The edge leg 21 passes through the middle of the annular plate 4.

[0052] The adjustment component 3 includes:

[0053] Column No. 1 31, the column No. 1 31 is bolted to the connection between the cross beam 15 and the longitudinal beam 14, and a No. 1 ring 32 is sleeved on the column No. 1 31, and the outer ring of the No. 1 ring 32 is evenly hinged to a No. 1 hinge plate 33, and the middle of the No. 1 hinge plate 33 is set through, and the end of the No. 1 column 31 close to the upper skin 131 is hinged to a No. 2 hinge plate 34, and the No. 2 hinge plate 34 is hinged to the No. 1 hinge plate 33; the upper end of the central support leg 22 is slidably connected to the column No. 1 31, and the uppermost end of the central support leg 22 is connected to the No. 1 ring 32.

[0054] The specific workflow is as follows:

[0055] The stainless steel floating plate of the present application adopts a new type of fully welded stainless steel inner floating plate, which adopts a structure of a crossbeam 15, a longitudinal beam 14, an edge plate 1, a lower skin 121 and an upper skin 131. The crossbeam 15, the longitudinal beam 14 and the edge plate 1 divide the entire floating plate into multiple compartments. The longitudinal beams 14, the crossbeam 15 and the edge plate 1 are fully welded. Each compartment is independent of each other. The lower skin 121 and the upper skin 131 are laid on the upper and lower surfaces. The upper skin 131, the lower skin 121, the crossbeam 15, the longitudinal beam 14 and the edge plate 1 are welded together, thus forming multiple enclosed spaces; the legs 2 are divided into two types: one is an edge leg 21, which is installed in the middle of each edge plate 1, and the central leg 22 is installed at the connection between the longitudinal beams 14 and the longitudinal beams 14;

[0056] During production, a sealing mounting edge 11 is fixed to the upper end of the edge plate 1, a lower skin mounting edge 12 is provided at the lower end of the edge plate 1, an upper skin mounting edge 13 is provided above the lower skin mounting edge 12, and the upper skin mounting edge 13 is fixed to the inner wall of the edge plate 1. Subsequently, both ends of the longitudinal beam 14 are welded to the edge plate 1, and the upper end of the longitudinal beam 14 is welded to the upper skin mounting edge 13, and the lower end of the longitudinal beam 14 is welded to the lower skin mounting edge 12. After the longitudinal beam 14 is welded, the cross beam 15 is welded. The height of the cross beam 15 is the same as that of the longitudinal beam 14. The two ends of the cross beam 15 between the longitudinal beam 14 and the edge plate 1 are respectively welded to the upper skin 131 mounting and the lower skin mounting edge 12 on the edge plate 1. , and welded on the longitudinal beams 14, the two ends of the crossbeams 15 between the longitudinal beams 14 are welded on the longitudinal beams 14, and after the crossbeams 15, the longitudinal beams 14 and the edge plates 1 are welded, the skin frame 16 is welded between the adjacent crossbeams 15, and the two ends of the plates at the upper and lower ends of the skin frame 16 are welded between the adjacent crossbeams 15, and the height of the skin frame 16 is the same as the height of the crossbeam 15, and then the lower skin 121 at the lower end is welded. First, the edge of the lower skin 121 is welded to the lower end of the lower skin installation along the 12, and the welding method is full welding, and then the lower skin 121 is fully welded with the longitudinal beams 14, the crossbeams 15, and the edge lower skin 121 of the skin frame 16, so that the lower skin 121 is welded to the edge Plate 1, longitudinal beam 14, cross beam 15 and skin skeleton 16; After the upper skin 131 is welded, the upper skin 131 is welded, and the edge of the upper skin 131 is welded to the upper end of the upper skin mounting edge 13, and the welding method is full welding; by welding the longitudinal beam 14 and the cross beam 15, and there are multiple compartments between the longitudinal beam 14 and the cross beam 15, then when the upper skin 131 and the lower skin 121 are welded to the upper skin mounting edge 13, the lower skin mounting edge 12, the cross beam 15 and the longitudinal beam 14, there are multiple separate compartments between the cross beam 15, the longitudinal beam 14 and the edge plate 1, which play a buoyancy role on the floating plate, and by welding the edge of the lower skin 121 to the lower skin mounting edge 12, the upper skin 1 31 is welded on the upper skin mounting edge 13. The upper skin 131 and the lower skin 121 are both a complete piece of steel plate. Only the edges are fully welded on the upper skin mounting edge 13 and the lower skin mounting edge 12 on the edge plate 1. There is no need to use a buoyancy box in the prior art, and it also avoids welding and using sealing gaskets between buoyancy boxes in the prior art. Thus, it is possible to achieve installation in place without using too many sealing gaskets and bolts. When sending and receiving oil inside the tank, the upper skin 131 and the lower skin 121 are the same whole as the longitudinal beam 14, the cross beam 15 and the edge plate 1. Therefore, when the floating plate swings, they will swing at the same time, and there will be no gap separation problem between adjacent buoyancy boxes in the prior art, thereby improving the sealing effect.

[0057] Furthermore, by providing an annular plate 4 at the lower end of the lower skin 121, and distributing a plurality of blades 41 in an annular manner on the inner wall of the annular plate 4, when the floating plate is located inside the storage tank, the floating plate is located inside the liquid inside the storage tank. When liquid is sent or received inside the storage tank, the floating plate will swing along with the swing of the liquid during the sending or receiving. When the liquid level swings, the liquid level swings within the separate compartment formed by the annular plate 4 and the blades 41. The amplitude of the liquid level swing within the space formed by the blades 41 will be blocked, thereby reducing the impact of the liquid level swing on the entire floating plate.

[0058] Then install the edge legs 21 and the central legs 22. The edge legs 21 are fixed to the middle of the edge plate 1 by bolts, and the edge legs 21 pass through the annular plate 4 when installed. The lower ends of the edge legs 21 and the central legs 22 are both provided with adjustable feet 23. Then install the central leg 22. First, bolt the No. 1 column 31 to the connection between the longitudinal beam 14 and the cross beam 15. The No. 1 column 31 is located inside the blade 41. The upper end of the central leg 22 is slidably connected. On the first column 31, the central leg 22 is located in the inner cavity of the blade 41. When the edge legs 21 and the central leg 22 are not under stress, the lowermost end of the central leg 22 is lower than the edge legs 21. A first ring 32 is slidably connected to the first column 31. The outer ring of the first ring 32 is evenly hinged to the first hinge plate 33. A second hinge plate 34 is provided at the end of the first column 31 away from the central leg 22, and the second hinge plate 34 is hinged to the first hinge plate 33.

[0059] When the float is used inside the storage tank, the float will rise as the liquid level inside the storage tank rises, and fall as the liquid level inside the storage tank falls; when the float is descending, the float will fall with the liquid level until the central leg 22 contacts the bottom of the storage tank. At this time, it should be noted that when the central leg 22 contacts the bottom of the storage tank, the edge leg 21 temporarily does not contact the bottom of the storage tank. At this time, the liquid level inside the storage tank is in an alert state. As the liquid level drops, the float moves downward, and the central leg 22 cannot move downward. The central leg 22 is squeezed by the bottom of the storage tank, and the central leg 22 moves upward on the No. 1 column 31. The central leg 22 slides upward on the No. 1 column 31. The central leg 22 squeezes the No. 1 ring 32, and the No. 1 ring 32 slides upward on the No. 1 column 31. When the No. 1 column 31 slides upward, the No. 1 hinged plate 33 squeezes the No. 2 hinged plate 33 The hinged plate 34 is squeezed. In the initial state, the middle parts of the No. 1 hinged plate 33 and the No. 2 hinged plate 34 protrude away from the No. 1 column 31. As the central leg 22 slides upward, the No. 1 ring 32 pushes the No. 1 hinged plate 33, and the No. 1 hinged plate 33 pushes the No. 2 hinged plate 34. The hinge between the No. 1 hinged plate 33 and the No. 2 hinged plate 34 rotates until the connection between the No. 1 hinged plate 33 and the No. 2 hinged plate 34 squeezes the upper wall of the cavity of the vane 41. At this time, the floating plate cannot move downward, and the edge leg 21 contacts the bottom of the tank; the central leg 22 and the No. 1 hinged plate 33 and the No. 2 hinged plate 34 on the No. 1 column 31 form a triangular bracket to improve the load-bearing capacity of the central leg 22; and the adjustable foot 23 can level the edge legs 21 and the central leg 22; so that all the edge legs 21 and the central leg 22 can carry the floating plate.

[0060] Example 2:

[0061] The outer ring of the annular plate 4 is provided with an annular groove 42, and a rubber sealing ring 43 is provided inside the annular groove 42; the middle part of the blade 41 is connected to the annular groove 42, and the middle part of the blade 41 is slidably connected with a sliding rod 44, and the end of the sliding rod 44 close to the annular groove 42 is in contact with the rubber sealing ring 43, and the end of the sliding rod 44 away from the annular groove 42 is provided with a downward inclined surface, and the part of the support leg 2 located inside the blade 41 is fixed with a protrusion 45, and the protrusion 45 is in contact with the inclined surface on the sliding rod 44.

[0062] The protrusion 45 is rotatably connected to a roller 46;

[0063] An arc-shaped groove 47 is formed on the inner wall of the annular groove 42 . An arc-shaped block 48 is provided inside the arc-shaped groove 47 . The arc-shaped block 48 is connected to the sliding rod 44 .

[0064] The specific workflow is as follows:

[0065] An annular groove 42 is provided on the outer ring of the annular plate 4, a rubber sealing ring 43 is provided inside the annular groove 42, and a slide rod 44 is slidably connected to the middle of the blade 41, the end of the slide rod 44 close to the first column 31 is provided with an inclined surface, and the end of the slide rod 44 close to the rubber sealing ring 43 contacts the rubber sealing ring 43, and a protrusion 45 is provided at the end of the central leg 22 located inside the blade 41. When the central leg 22 slides upward on the first column 31, the protrusion 45 contacts the inclined surface on the slide rod 44, and the protrusion 45 squeezes the inclined surface on the slide rod 44 After the inclined surface on the slide rod 44 is squeezed, the slide rod 44 moves toward the position of the rubber sealing ring 43 in the middle of the blade 41. The slide rod 44 pushes the rubber sealing ring 43, thereby increasing the friction between the outer side of the float and the inner wall of the tank, further preventing the float from falling to the ground inside the tank. In addition, by arranging rollers 46 on the protrusions 45, when the push block squeezes the slide rod 44, the rollers 46 on the protrusions 45 contact the inclined surface on the slide rod 44. When the rollers 46 contact the slide rod 44, the rollers 46 rotate, thereby reducing the wear between the slide rod 44 and the protrusions 45.

[0066] In addition, an arc groove 47 is provided on the inner wall of the annular groove 42, and an arc block 48 is provided inside the arc groove 47, and the arc block 48 is connected to the slide rod 44; when the slide rod 44 pushes the rubber sealing ring 43, the slide rod 44 pushes the arc block 48, and the arc block 48 pushes the rubber sealing ring 43, and the arc block 48 pushes the rubber sealing ring 43 to squeeze the inner wall of the storage tank, thereby increasing the contact area between the slide rod 44 and the rubber sealing ring 43, thereby increasing the contact area between the rubber sealing ring 43 and the inner wall of the storage tank, and increasing the friction between the floating plate and the storage tank.

[0067] Example 3:

[0068] The difference between this embodiment and the second embodiment is that this embodiment is a supplementary description of the annular plate 4 and the annular groove 42 in the second embodiment. Specifically, this embodiment can exist as a parallel embodiment of the second embodiment; specifically, it includes:

[0069] The outer wall of the annular plate 4 is provided with an annular groove 42, a rubber sealing ring 43 is provided inside the annular groove 42, the inner wall of the annular groove 42 is provided with a strip groove 49, the strip groove 49 is annular, the strip groove 49 is connected to the middle part of the blade 41, and the end of the sliding rod 44 close to the rubber sealing ring 43 is sealed and slidably connected to the middle part of the blade 41.

[0070] The specific workflow is as follows:

[0071] The inner wall of the annular plate 4 is provided with an annular groove 42, and the inner wall of the annular groove 42 is provided with a strip groove 49. The strip groove 49 is annular, so that the strip groove 49 is connected to the middle part of the vane plate 41; and the end of the slide rod 44 close to the rubber sealing ring 43 is sealed and slidably connected to the middle part of the vane plate 41. At this time, when the central support leg 22 moves upward on the No. 1 column 31, the protrusion 45 pushes the inclined surface of the slide rod 44. When the slide rod 44 slides inside the vane plate 41, since the slide rod 44 and the cavity in the middle part of the vane plate 41 are sealed and slidably connected, when the slide rod 44 moves toward the rubber sealing ring 43 inside the vane plate 41, the cavity between the rubber sealing ring 43 and the slide rod 44 is squeezed, and the gas is squeezed into the strip groove 49. The internal air pressure of the strip groove 49 increases, pushing the rubber sealing ring 43 to expand. When the rubber sealing ring 43 expands, the outer ring of the floating plate squeezes the storage tank more, and the friction force of the floating plate on the storage tank is increased.

[0072] By increasing the friction between the float and the inner wall of the tank and enhancing the sealing effect as the liquid level in the tank drops, on the one hand, the edge legs 21 and the central legs 22 support the float, and the friction between the float and the inner wall of the tank is enhanced, the downward resistance of the float is increased, and the outer side of the float is stuck with the inner wall of the tank, which reduces the possibility of the float falling to the ground to a certain extent; on the other hand, when the float floats up and down with the liquid level, the friction between the float and the inner wall of the tank is reduced, avoiding the problem of the float getting stuck between the float and the tank.

[0073] Example 4:

[0074] A tripod 231 is provided at the lower end of the adjustable foot 23 .

[0075] The specific workflow is as follows:

[0076] By providing a tripod at the lower end of the adjustable foot 23, when the adjustable foot 23 contacts the bottom of the storage tank, the tripod 231 at the lower end of the adjustable foot 23 contacts the bottom of the storage tank, so that the edge legs 21 and the central leg 22 are supported on the bottom of the storage tank. According to the stability of the triangle, after 3-5 years of use, the edge legs 21 and the central leg 22 have better stability when supporting the floating plate.
