Description

Technical Field

[0001] This utility model relates to the field of fully liquid-contact internal floating roof technology, specifically to a stainless steel honeycomb fully liquid-contact internal floating roof. Background Technology

[0002] The fully liquid-contact internal floating roof is suitable for liquid storage scenarios in industries such as petrochemicals, food and beverages, and pharmaceuticals. It can float with the rise and fall of the liquid level, effectively reducing liquid evaporation, oxidation, and pollution, reducing volatilization, improving storage safety and quality, and enhancing economic benefits.

[0003] Currently, stainless steel fully wetted internal floating roofs are usually box-type structures. This type of floating roof is composed of multiple boxes spliced ​​together, which makes the structure relatively complex. Stress concentration is prone to occur at the splicing points, and the resistance to deformation is relatively weak.

[0004] The existing fully liquid-contact internal floating roof structure has low strength and poor sealing performance with the tank wall. It cannot be adjusted according to the sealing gap requirements, resulting in limited sealing performance between the floating roof and the inner wall of the tank. Therefore, a stainless steel honeycomb fully liquid-contact internal floating roof is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a stainless steel honeycomb fully liquid-contact internal floating roof, which provides storage tanks with a set of stainless steel honeycomb fully liquid-contact internal floating roofs with good strength and high stability. By using stainless steel honeycomb plates, the buoyancy units of the entire floating roof are independently and evenly distributed. Compared with the existing box-type floating roofs, the overall structure of this application has higher strength, can withstand greater pressure and impact, and has strong resistance to deformation.

[0006] The technical solution adopted by this utility model to solve its technical problem is a stainless steel honeycomb type fully liquid-contact internal floating disk, including a floating disk and a sealing mechanism, wherein the sealing mechanism is disposed on the outer periphery of the floating disk;

[0007] The floating roof includes a stainless steel support ring and a stainless steel honeycomb plate. The stainless steel support ring is sleeved around the outer periphery of the stainless steel honeycomb plate and welded to the outer periphery of the stainless steel honeycomb plate. Stainless steel panels are welded to the top and bottom of the stainless steel honeycomb plate.

[0008] By adopting the above technical solution, a stainless steel honeycomb fully liquid-contact internal floating roof with good strength and high stability is provided for the storage tank through the components composed of the floating roof and sealing mechanism. Through the use of stainless steel honeycomb plates, the buoyancy units of the entire floating roof are independently and evenly distributed. Compared with the existing box-type floating roof, the overall structure of this application has higher strength, can withstand greater pressure and impact, and has strong resistance to deformation.

[0009] Specifically, the sealing mechanism includes a tongue-shaped spring steel sheet, an elastic pad, and a fireproof surface layer. The tongue-shaped spring steel sheet is evenly spaced along the outer circumference of the stainless steel support ring. The elastic pad is located outside the tongue-shaped spring steel sheet and is glued to it. The fireproof surface layer is located outside the elastic pad and is glued to it.

[0010] The tongue-shaped spring steel sheet, elastic pad, and top of the fireproof surface layer are connected to the outer periphery of the stainless steel support ring by sealing bolts.

[0011] By adopting the above technical solution and setting the tongue-shaped spring steel sheet, the sealing mechanism can have a metal elastomer support structure with a certain strength on the outer periphery of the floating plate, so that the sealing mechanism can have a certain support strength while generating an elastic seal with the inner wall of the tank.

[0012] Specifically, the elastic pad is made of nitrile rubber, and an air chamber is provided in the middle of the elastic pad. An air pump is installed on the top of the floating plate, and the exhaust end of the air pump is connected to the air chamber through a pipe.

[0013] The air pump is equipped with a pressure switch at the exhaust end.

[0014] By adopting the above technical solution, through the setting of the elastic pad and the internal inflation chamber, personnel can inflate the inflation chamber with an air pump to expand the elastic pad, thereby further increasing the sealing performance of the fireproof surface layer in contact with the inner wall of the tank.

[0015] Specifically, the fireproof surface layer is made of silicone-coated fiberglass cloth.

[0016] By adopting the above technical solution and setting a fireproof surface layer, the sealing performance between the lower medium and the upper space of the floating roof can be improved. The fireproof surface layer made of silicone-coated fiberglass cloth has good waterproof and oil-proof properties, which improves the sealing performance of the sealing mechanism.

[0017] Specifically, the floating platform is provided with a manhole and a guide rod hole, and the stainless steel support ring is welded to a support column.

[0018] The beneficial effects of this utility model are as follows: The assembly consisting of a floating roof and a sealing mechanism provides the storage tank with a stainless steel honeycomb fully wetted internal floating roof that offers high strength and stability. The use of stainless steel honeycomb panels ensures that the buoyancy units of the entire floating roof are independently and evenly distributed. Through the elastic pad and internal inflation chamber, personnel can inflate the inflation chamber using an air pump, causing the elastic pad to expand and further increasing the sealing performance between the fireproof surface layer and the inner wall of the tank. The inflation expansion better adapts to the sealing requirements of different gaps. The fireproof surface layer improves the sealing performance between the lower medium and the upper space of the floating roof. The fireproof surface layer, made of silicone-coated fiberglass cloth, has good waterproof and oil-proof properties, improving the sealing performance of the sealing mechanism. This solves the problem that existing fully wetted internal floating roof structures have low structural strength and poor sealing performance with the tank wall, making it impossible to adjust according to the required sealing gap, resulting in limited sealing performance between the floating roof and the inner wall of the tank.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3 As shown, the stainless steel honeycomb type fully liquid-contact internal floating disk of this utility model includes a floating disk 1 and a sealing mechanism 2, wherein the sealing mechanism 2 is disposed on the outer periphery of the floating disk 1.

[0026] The floating roof 1 includes a stainless steel support ring 11 and a stainless steel honeycomb plate 12. The stainless steel support ring 11 is sleeved on the outer periphery of the stainless steel honeycomb plate 12 and welded to the outer periphery of the stainless steel honeycomb plate 12. Stainless steel panels 13 are welded to the top and bottom of the stainless steel honeycomb plate 12.

[0027] The present invention also includes that the sealing mechanism 2 includes a tongue-shaped spring steel sheet 21, an elastic pad 22 and a fireproof surface layer 23. The tongue-shaped spring steel sheet 21 is arranged at equal intervals along the outer periphery of the stainless steel support ring 11. The elastic pad 22 is located outside the tongue-shaped spring steel sheet 21 and is glued to the tongue-shaped spring steel sheet 21. The fireproof surface layer 23 is arranged outside the elastic pad 22 and is glued to and fixed to the elastic pad 22.

[0028] The top of the tongue-shaped spring steel sheet 21, the elastic pad 22, and the fireproof surface layer 23 are connected to the outer periphery of the stainless steel support ring 11 by sealing bolts.

[0029] When in use, the tongue-shaped spring steel sheet 21 enables the sealing mechanism 2 to have a certain strength of metal elastomer support structure on the outer periphery of the floating plate 1, so that the sealing mechanism 2 can have a certain support strength while elastically sealing with the inner wall of the tank.

[0030] The present invention also includes that the elastic pad 22 is made of nitrile rubber, the elastic pad 22 has an inflation chamber 221 in the middle, the floating plate 1 is equipped with an air pump 3, and the exhaust end of the air pump 3 is connected to the inflation chamber 221 through a pipe.

[0031] The exhaust end of the air pump 3 is equipped with a pressure switch, and the control output end of the pressure switch is electrically connected to the control input end of the air pump 3 through a wire.

[0032] When in use, based on the setting of the elastic pad 22 and the internal inflation chamber 221, personnel can inflate the inflation chamber 221 with air pump 3 to expand the elastic pad 22, thereby further increasing the sealing between the fireproof surface layer 23 and the inner wall of the tank.

[0033] The pressure switch detects the pressure intensity between the exhaust end of the air pump 3 and the inside of the inflation chamber 221. If the air pressure value exceeds the set value, the air pump 3 stops supplying pressure.

[0034] This utility model also includes that the fireproof surface layer 23 is made of silicone-coated fiberglass cloth material.

[0035] When in use, the fireproof surface layer 23 can improve the sealing between the lower medium and the upper space of the floating board. The fireproof surface layer 23, made of silicone coated fiberglass cloth, has good waterproof and oil-proof properties, which improves the sealing performance of the sealing mechanism 2.

[0036] This utility model also includes that the floating plate 1 is provided with a manhole 14 and a guide rod hole 15, and the stainless steel support ring 11 is welded to a support column 16.

[0037] Manhole 14 allows maintenance personnel to easily access the area below the floating roof. The support column 16 provides a certain support space between the bottom of the floating roof 1 and the bottom of the tank, facilitating personnel descent. Guide rod hole 15 allows the guide rod in the tank to be inserted through, ensuring the overall directional control of the floating roof's lifting and lowering.

[0038] In use, this utility model provides buoyancy to the floating roof 1 within the storage tank through the stainless steel honeycomb plate 12 and the honeycomb cavity formed inside. The use of the stainless steel honeycomb plate 12 makes the buoyancy units of the entire floating roof independent and evenly distributed. Through the setting of the elastic pad 22 and the internal inflation chamber 221, personnel can inflate the inflation chamber 221 with air pump 3 to expand the elastic pad 22, thereby further increasing the sealing performance of the fireproof surface layer 23 in contact with the inner wall of the tank. The inflation expansion can better adapt to the sealing requirements of different gaps. The setting of the fireproof surface layer 23 can improve the sealing performance between the lower medium and the upper space of the floating roof. The fireproof surface layer 23, made of silicone coated fiberglass cloth, has good waterproof and oil-proof properties, which improves the sealing performance of the sealing mechanism 2.
