Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, in particular to an elastic mechanical shoe-shaped high-efficiency sealing device. Background Art

[0002] In the chemical, petroleum, pharmaceutical, food, steel and other industries, efficient sealing of tank floats has always been one of the key technologies to ensure production safety, reduce VOCs emissions and improve economic benefits.

[0003] In large liquid storage equipment such as oil tanks, since the oil level fluctuates with changes in storage volume, traditional sealing devices often find it difficult to maintain continuous close contact with the tank wall, resulting in a gap between the float and the tank wall, which in turn causes leakage risks. In addition, an oil and gas space is formed between the elastic plate, the outer edge plate of the float, and the liquid surface, further increasing the risk of oil and gas flash explosions.

[0004] The sealing system of a floating roof tank is the weakest link in the safe operation of a large tank. Leakage in the tank seal can cause large amounts of organic gases to volatilize into the atmosphere, seriously polluting the environment. It also causes significant loss of oil products and significantly affects economic benefits. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the prior art by proposing a highly efficient elastic mechanical shoe-shaped sealing device. This device provides a sealing member with a sponge structure between the floating plate and the sealing elastic plate to improve the seal between the floating plate and the tank body, effectively reducing the volatilization of the liquid phase within the tank body. Furthermore, the support frame and elastic member act to counteract the sealing elastic plate to maintain the seal between the sealing elastic plate and the tank body. The sealing elastic plate always maintains contact with the tank wall, thereby reducing the leakage and volatilization of raw materials.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An elastic mechanical shoe-shaped high-efficiency sealing device, comprising:

[0008] a floating plate built into the interior of the tank;

[0009] Sealing elastic plates, which are mounted on the outside of the floating plate by bolts and are in close contact with the tank wall;

[0010] A sealing body, which is distributed in an annular shape and installed between the floating plate and the sealing elastic plate;

[0011] The support frame is installed below the outer edge plate of the floating plate through bolts, and the other end of the support frame is installed with an elastic member in contact with the sealing elastic plate.

[0012] The utility model is further configured such that the support frame is configured as a triangle.

[0013] The utility model is further configured such that the support frames are distributed in an annular array on the inner side of the sealing elastic plate.

[0014] The utility model is further configured such that the support frame is located below the sealing body.

[0015] The utility model is further configured such that the sealing body is in close contact with the floating disc and the sealing elastic plate, and the sealing body is constructed as a capsule-type adhesive tape with a sponge material inside.

[0016] The beneficial effects of the utility model are as follows: the utility model provides a sealing body with a sponge structure between the floating plate and the sealing elastic plate to fill the sealing between the floating plate and the tank body, and can effectively reduce the volatilization of the liquid phase in the tank body, and under the action of the support frame and the elastic member, the sealing elastic plate can be offset to maintain the sealing between the sealing elastic plate and the tank body, and the sealing elastic plate always keeps in contact with the tank wall and does not separate, thereby reducing the leakage and volatilization of raw materials.

[0017] This elastic mechanical shoe-shaped high-efficiency sealing device is provided with a sealing body. When the tank body is sealed by the floating plate, the sponge-structured sealing body can effectively reduce the volatilization of the liquid phase in the tank body. Moreover, as the floating plate moves up and down inside the tank body, the sealing body can always remain tightly connected between the sealing elastic plate and the floating plate due to the elastic expansion and contraction movement of the sealing body, thereby improving the sealing effect.

[0018] This elastic mechanical shoe-shaped high-efficiency sealing device is equipped with a support frame and an elastic member. The floating plate can maintain close contact with the tank body through the sealing elastic plate on its outer side. When the floating plate moves up and down with the rise and fall of the liquid level in the tank body, in order to avoid the frequent movement of the sealing elastic plate affecting the sealing effect with the tank body, the sealing elastic plate can be offset by the support frame and the elastic member to maintain the sealing between the sealing elastic plate and the tank body. The sealing elastic plate always keeps in contact with the tank wall and does not separate, thereby reducing the leakage and volatilization of raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] Reference Figure 1-2, an elastic mechanical shoe-shaped high-efficiency sealing device, comprising: a tank body 1, the interior of which is constructed with a raw material storage space for storing various liquid or gas raw materials; a floating plate 2, which is connected to the interior of the tank body 1 and can float up and down as the liquid level of the liquid or gas in the tank changes. The design of the floating plate 2 helps to reduce the evaporation loss of the liquid and improve the storage efficiency; a sealing elastic plate 7, which is installed on the outside of the floating plate 2 by bolts 4 and is in close contact with the tank body 1, ensuring the sealing between the floating plate 2 and the tank body 1 and preventing the leakage of liquid or gas. The material of the sealing elastic plate 7 must have good elasticity and corrosion resistance to adapt to the floating of the floating plate 2 and the changes in the environment in the tank; a sealing body 3, which is distributed in an annular shape and is installed in the tank body. The sealing effect is further enhanced between the floating plate 2 and the sealing elastic plate 7 to ensure the sealing between the floating plate 2 and the sealing elastic plate 7; the support frame 5 is installed at the lower outer side of the floating plate 2 by bolts 4, and the other end of the support frame 5 is installed with an elastic member 6 in contact with the sealing elastic plate 7, so that the support frame 5 and the elastic member 6 can be offset against the sealing elastic plate 7, providing support for the sealing elastic plate 7 and ensuring close contact between the sealing elastic plate 7 and the tank body 1, thereby achieving efficient sealing between the floating plate 2 and the tank body 1 and effectively preventing leakage of liquid or gas. The elastic design of the sealing elastic plate 7 and the elastic member 6 enables the entire sealing device to adapt to changes in different liquid levels and the environment inside the tank, maintaining good sealing performance.

[0027] Furthermore, the support frame 5 is constructed in a triangular configuration. Through this design, the triangular support structure has high mechanical stability. The triangular support structure is compact and can maximize the use of the space inside the tank body 1, thereby keeping the sealing elastic plate 7 always in contact with the tank wall.

[0028] Furthermore, the support frames 5 are distributed in a circular array on the inner side of the sealing elastic plate 7. Through this design, the sealing elastic plate 7 can be supported more effectively, so that it maintains close contact with the tank body 1, avoiding single-point or local overload, and ensuring the overall stability and durability of the sealing device. The evenly distributed support frames 5 can also effectively reduce the risk of deformation or damage of the sealing elastic plate 7 due to uneven load. The even distribution of the support frames 5 can also reduce the sealing gap caused by excessive local force on the sealing elastic plate 7, further enhancing the sealing effect.

[0029] Furthermore, the support frame 5 is positioned below the sealing body 3. This design provides stable support for the entire sealing structure, allowing the sealing body 3 to fit more stably between the floating plate 2 and the sealing elastic plate 7. This effectively prevents seal failure caused by uneven force or floating of the sealing body 3. The downward position of the support frame 5 helps to better distribute the pressure exerted by the floating plate 2 on the sealing structure. When the floating plate 2 moves up and down, the support frame 5 absorbs and distributes this pressure, ensuring close contact between the sealing body 3 and the sealing elastic plate 7.

[0030] Furthermore, the sealing body 3 is in close contact with the floating plate 2 and the sealing elastic plate 7, and the sealing body 3 is constructed as a capsule-type tape with a sponge material wrapped inside. Through this design, the sealing body 3 wrapped with the sponge material has good compression elasticity and resilience, and can form a close contact with the floating plate 2 and the sealing elastic plate 7. This close contact reduces the space for oil and gas volatilization, helps prevent liquid volatilization, and ensures the efficient sealing performance of the sealing device. At the same time, the sponge material can also adapt to the slight floating of the floating plate and maintain the stability of the sealing effect.

[0031] Working principle: When using the present invention, first, the float 2 can float up and down inside the tank body 1 as the liquid level rises and falls, and at this time, the sealing body with a sponge structure can effectively reduce the volatilization of the liquid phase in the tank body 1, and as the float 2 moves up and down inside the tank body 1, due to the elastic expansion and contraction of the sealing body 3, the sealing body 3 can always remain tightly connected between the sealing elastic plate 7 and the float 2, thereby improving the sealing effect. The float 2 can maintain close contact with the tank body 1 through the sealing elastic plate 7 on its outer side, and when the float 2 moves up and down as the liquid level in the tank body 1 rises and falls, in order to avoid the frequent movement of the sealing elastic plate 7 affecting the sealing effect with the tank body 1, the support frame 5 and the elastic member 6 can be used to offset the sealing elastic plate 7 to maintain the sealing between the sealing elastic plate 7 and the tank body 1. The sealing elastic plate 7 always remains in contact with the tank wall and does not separate, thereby reducing leakage and volatilization of raw materials.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
