Description

Technical Field

[0001] This utility model relates to the technical field of floating roof sealing structure, specifically to a storage tank floating roof sealing structure. Background Technology

[0002] The floating roof sealing ring is a sealing device installed on the edge of the floating roof. It is mainly used to ensure the sealing between the floating roof and the inner wall of the storage tank and to prevent liquid leakage. Its core structure includes sealing strips made of elastic materials such as oil-resistant rubber, which achieve the sealing effect through physical structural deformation or pressure.

[0003] Existing technologies are prone to problems such as positional displacement of the floating roof during raising and lowering due to severe deformation in some parts after long-term use. Therefore, a new tank floating roof sealing structure is proposed, which uses an auxiliary positioning structure to avoid severe wear caused by long-term deformation of the seals. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a tank floating roof sealing structure, which uses an auxiliary positioning structure to avoid the problem of severe wear caused by long-term deformation of the sealing components.

[0005] The technical solution adopted by this utility model to solve its technical problem is a storage tank floating roof sealing structure, including a tank body, a floating roof body, a floating pipe, a support column, a support roller frame and a through hole. The outer periphery of the floating roof body is equipped with an annular support frame by bolts.

[0006] The top and bottom of the inner wall of the annular support frame are respectively fixed with sealing ring A and sealing ring B by bolts. The inner wall of the support roller frame is connected with positioning rollers through rotating shafts. The inner side of the support roller frame is connected with support brackets through through openings.

[0007] By adopting the above technical solution, the floating pipe at the bottom of the floating roof body mainly plays the role of floating with the liquid level and keeping the oil outlet always above the liquid surface. The support column limits the maximum drop height of the floating roof to prevent the floating roof from directly contacting the bottom of the tank, thus preventing corrosion or deformation.

[0008] The sealing rings A and B on the inner wall of the annular support frame are made of elastic material and are in contact with the inner wall of the tank. They maintain an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. This is especially suitable for storing volatile liquids such as petroleum and chemical raw materials. The support bracket is fixed between sealing rings A and B to provide auxiliary support and prevent the seals from detaching from the inner wall of the annular support frame due to long-term use.

[0009] Meanwhile, the positioning rollers are supported by the support roller frame, and the positioning rollers are in contact with the inner wall of the tank, positioned between sealing ring A and sealing ring B to achieve an auxiliary positioning effect, avoiding the problem of severe wear caused by long-term deformation of the seals, and ensuring the lifting stability of the floating roof.

[0010] Specifically, the tank body is equipped with a floating roof body, and the floating pipes are evenly distributed at the bottom of the floating roof body.

[0011] By adopting the above technical solution, the floating pipe at the bottom of the floating roof body mainly serves to float with the liquid level and keep the oil outlet always above the liquid surface.

[0012] Specifically, a support column is installed between the bottom of the floating roof body and the corresponding floating tube.

[0013] By adopting the above technical solution, the maximum descent height of the floating roof is limited by the support pillars, preventing direct contact between the floating roof and the bottom of the tank, which could lead to corrosion or deformation.

[0014] Specifically, both sealing ring A and sealing ring B are made of elastomeric material, and the outer periphery of both sealing ring A and sealing ring B is in contact with the inner wall of the tank.

[0015] By adopting the above technical solution, the sealing rings A and B on the inner wall of the annular support frame are made of elastic material and are in contact with the inner wall of the tank. They maintain an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. This is especially suitable for storage scenarios of volatile liquids such as petroleum and chemical raw materials.

[0016] Specifically, the inner wall of the annular support frame is uniformly equipped with support roller frames by bolts around the center position, the positioning rollers are all in contact with the inner wall of the tank, and the inner side of the support roller frames is provided with through holes.

[0017] By adopting the above technical solution, the positioning roller is supported and fixed by the support roller frame, and the support frame can pass through through the through hole.

[0018] Specifically, the top and bottom ends of the support bracket are respectively bolted between sealing ring A and sealing ring B, and the annular support frame, support roller frame, positioning roller and support bracket are all made of stainless steel.

[0019] By adopting the above technical solution, the positioning rollers are in contact with the inner wall of the tank and positioned between sealing ring A and sealing ring B to achieve an auxiliary positioning effect, avoiding the problem of severe wear caused by long-term deformation of the sealing components, and ensuring the lifting stability of the floating roof.

[0020] The beneficial effects of this utility model are:

[0021] (1) The storage tank floating roof sealing structure described in this utility model uses sealing rings A and B, which are made of elastic material, to contact and adhere to the inner wall of the tank. This maintains an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. It is especially suitable for storage scenarios of volatile liquids such as petroleum and chemical raw materials. The support bracket is fixed between sealing rings A and B to achieve an auxiliary support effect and prevent the sealing parts from detaching from the inner wall of the annular support frame due to long-term use.

[0022] (2) The storage tank floating roof sealing structure described in this utility model supports the positioning rollers by means of the support roller frame, and the positioning rollers are in contact with the inner wall of the tank and are located between the sealing ring A and the sealing ring B to achieve the auxiliary positioning effect, so as to avoid the problem of severe wear caused by long-term deformation of the sealing parts and ensure the lifting stability of the floating roof.

[0027] 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.

[0028] To avoid the problem of severe wear caused by long-term deformation of the seals, such as Figure 1-2 As shown, the storage tank floating roof sealing structure of this utility model includes a tank body 1, a floating roof body 2, a floating pipe 3, a support column 4, a support roller frame 8, and a through hole 10. The floating roof body 2 is surrounded by an annular support frame 5 by bolts.

[0029] The top and bottom of the inner wall of the annular support frame 5 are respectively fixed with sealing rings A6 and B7 by bolts. The inner wall of the support roller frame 8 is connected with positioning rollers 9 by rotating shafts. The inner side of the support roller frame 8 is connected with support brackets 11 through through openings 10.

[0030] During use, the float pipe 3 at the bottom of the float body 2 mainly serves to float with the liquid level and keep the oil outlet always above the liquid surface. The support column 4 limits the maximum drop height of the float to prevent the float from directly contacting the bottom of the tank, which could lead to corrosion or deformation.

[0031] The sealing rings A6 and B7 on the inner wall of the annular support frame 5 are made of elastic material and are in contact with the inner wall of the tank 1, maintaining an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. This is especially suitable for storage scenarios of volatile liquids such as petroleum and chemical raw materials. The support frame 11 is fixed between the sealing rings A6 and B7 to achieve an auxiliary support effect and prevent the seals from detaching from the inner wall of the annular support frame 5 due to long-term use.

[0032] Meanwhile, the positioning rollers 9 are supported by the support roller frame 8, and the positioning rollers 9 are in contact with the inner wall of the tank body 1, positioned between the sealing rings A6 and B7 to achieve an auxiliary positioning effect, avoiding the problem of severe wear caused by long-term deformation of the sealing components, and ensuring the lifting stability of the floating roof.

[0033] To avoid severe wear caused by long-term deformation of the seal, for example, such as Figure 1 As shown, the present invention also includes a floating plate body 2 inside the tank body 1, and the floating pipes 3 are evenly arranged at the bottom of the floating plate body 2.

[0034] When in use, the float pipe 3 at the bottom of the float body 2 mainly serves to float with the liquid level and keep the oil outlet always above the liquid surface.

[0035] For example, such as Figure 1 As shown, the present invention also includes a support column 4 installed between the bottom of the floating plate body 2 and the floating tube 3.

[0036] During use, the support column 4 limits the maximum drop height of the floating roof to prevent direct contact between the floating roof and the bottom of the tank, which could lead to corrosion or deformation.

[0037] For example, such as Figure 1 As shown, the present invention also includes that the sealing ring A6 and the sealing ring B7 are both made of elastomeric material, and the outer periphery of the sealing ring A6 and the sealing ring B7 is in contact with the inner wall of the tank body 1.

[0038] During use, the sealing rings A6 and B7 on the inner wall of the annular support frame 5 are made of elastomeric material and are in contact with the inner wall of the tank 1, maintaining an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. This is especially suitable for storage scenarios of volatile liquids such as petroleum and chemical raw materials.

[0039] For example, such as Figure 1 , Figure 2As shown, the present invention also includes a roller frame 8 evenly installed around the center position on the inner wall of the annular support frame 5 by bolts, the positioning rollers 9 are all in contact with the inner wall of the tank body 1, and the inner side of the roller frame 8 is provided with a through hole 10.

[0041] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes the top and bottom ends of the support bracket 11 being bolted between the sealing ring A6 and the sealing ring B7, respectively. The annular support frame 5, the support roller frame 8, the positioning roller 9 and the support bracket 11 are all made of stainless steel.

[0042] During use, the positioning rollers 9 are in contact with the inner wall of the tank 1 and are positioned between the sealing rings A6 and B7 to achieve an auxiliary positioning effect, thereby avoiding the problem of severe wear caused by long-term deformation of the seals and ensuring the stability of the floating roof's lifting.

[0043] In use, the floating pipe 3 at the bottom of the floating roof body 2 mainly plays the role of floating with the liquid level and keeping the oil outlet always above the liquid surface. The support column 4 is used to limit the maximum drop height of the floating roof and prevent the floating roof from directly contacting the bottom of the tank, which could lead to corrosion or deformation.

[0044] The sealing rings A6 and B7 on the inner wall of the annular support frame 5 are made of elastic material and are in contact with the inner wall of the tank 1, maintaining an effective seal when the liquid level rises or falls, preventing gas penetration and liquid evaporation. This is especially suitable for storage scenarios of volatile liquids such as petroleum and chemical raw materials. The support frame 11 is fixed between the sealing rings A6 and B7 to achieve an auxiliary support effect and prevent the seals from detaching from the inner wall of the annular support frame 5 due to long-term use.

[0045] Meanwhile, the positioning rollers 9 are supported by the support roller frame 8, and the positioning rollers 9 are in contact with the inner wall of the tank body 1, positioned between the sealing rings A6 and B7 to achieve an auxiliary positioning effect, avoiding the problem of severe wear caused by long-term deformation of the sealing components, and ensuring the lifting stability of the floating roof.
