Description

Technical Field

[0001] The utility model relates to the technical field of oil tank storage equipment, in particular to a round table-shaped internal floating roof with an airbag. Background Art

[0002] In the field of oil tank storage, the internal floating roof is a crucial piece of equipment. The internal floating roof is a structure used inside an oil tank, designed to reduce the evaporation loss of oil and gas during storage, and improve safety and environmental protection. The internal floating roof is usually made of lightweight materials such as aluminum alloy, fiberglass, or polyethylene to ensure good buoyancy and corrosion resistance. The internal floating roof is designed with a support device to enable it to float at different oil levels and maintain stability. The periphery of the floating roof is usually equipped with a sealing device such as a floating ring to ensure a good seal between the floating roof and the oil tank wall, reducing steam leakage. The working principle of the internal floating roof is: the internal floating roof floats on the oil surface, rises and falls with the change of the oil level, and can keep in contact with the liquid level, minimizing the evaporation space of the oil and gas.

[0003] The functions of the internal floating roof are as follows:

[0004] 1. Reduce the evaporation loss of oil and gas:

[0005] The internal floating roof directly floats on the oil surface, which can effectively reduce the evaporation area of the oil and gas in the oil tank, reduce the oil and gas loss caused by temperature change and air pressure change, thereby improving the economic benefit and environmental protection performance of the oil product.

[0006] 2. Prevent the intrusion of moisture and pollutants:

[0007] The internal floating roof floats on the oil surface, which can prevent external moisture (such as precipitation) from entering the tank, thus reducing the pollution of the oil product by water. In addition, reducing the intrusion of impurities helps to maintain the quality of the oil product.

[0008] 3. Improve safety:

[0009] By reducing the volume and evaporation of the oil and gas, the internal floating roof helps to reduce the concentration of flammable and explosive gases, reduce the risk of fire and explosion, and enhance the overall safety of the oil tank.

[0010] 4. Reduce the pressure in the storage space:

[0011] The floating roof inside the oil tank can reduce the fluctuation of the gas pressure, maintaining the structural effectiveness and stability of the oil tank.

[0012] 5. Facilitate monitoring and maintenance:

[0013] The internal floating roof provides a stable liquid level height, which helps to accurately measure the oil volume in the oil tank, and monitoring equipment such as measuring instruments and floating liquid level sensors can be installed on the floating roof, thereby improving the convenience and accuracy of monitoring.

[0014] Internal floating roofs are widely used in storage tanks for various petroleum and chemical products, especially in situations where high requirements are placed on vapor loss and environmental protection. Whether in large oil companies, chemical plants or refineries, internal floating roofs play an important role.

[0015] In summary, the internal floating roof is an effective accessory for oil storage facilities. It improves the storage safety, environmental protection and economy of oil products in various ways and is an important part of modern oil and gas storage technology. Due to deficiencies in the structural design of existing floating roofs, the sealing performance and stability of the floating roofs are relatively low, and leaks and other situations are likely to occur during long-term operation, affecting normal production operations. To solve these problems, the present utility model provides a round table-shaped internal floating roof with an airbag. Content of the Utility Model

[0034] By providing a frustum-shaped internal floating roof with airbags in the embodiments of the present application, the technical problems that in the existing floating roof, due to insufficient structural design, the sealing performance and stability of the floating roof are relatively low, and leakage and other situations are likely to occur during long-term operation, affecting normal production operations are effectively solved. Embodiment

[0036] As Figures 1-4 shown, in view of the problems existing in the prior art, the present invention provides a frustum-shaped internal floating roof with airbags, which includes a floating plate body 1, an inflation pipeline 5, and airbags 2 on the side. A top cover 4 is provided at the top of the floating plate body 1, and an air pump 10 is provided at the center position of the top cover 4. Inflation holes 3 and exhaust holes 6 are respectively provided on both sides of the airbag 2, and the air pump 10 is connected to the inflation hole 3 through the inflation pipeline 5 to inflate the airbag 2. A fixing structure 11 is arranged inside the floating plate body 1.

[0037] The fixed structure 11 is composed of two parts. One part is a fixing plate in the shape of an outer hexagon with an inner hexagram, and the other part is composed of a hexagon and six extended reinforcing rods. The fixed structure 11 is arranged inside the floating plate body 1, increasing the lateral strength of the floating plate and making the structure of the floating plate body 1 more stable. A bottom cover 7 is arranged at the bottom of the floating plate body 1. Sealing rings are arranged between both the bottom cover 7 and the top cover 4 and the floating plate body 1 to prevent liquid from entering and maintain the airtightness of the internal floating roof. Eight symmetrically arranged fixing frames 8 are arranged below the bottom cover 7, and each fixing frame 8 is respectively connected to a counterweight 9 to adjust the gravity of the entire internal floating roof, enabling the entire internal floating roof to float tightly on the oil surface, reducing steam loss, and also preventing the entry of precipitation, dust, and other impurities, thereby reducing the pollution of the oil product.

[0038] Working principle: The floating plate body 1 is designed in a frustum shape, wider at the bottom and narrower at the top, making it more stable when floating on the oil surface. Moreover, a ring of airbags 2 is arranged on the outside, which can greatly reduce the lateral impact force and buffer the pressure on the floating plate body 1. Two sets of fixed structures 11 are arranged inside. The two sets of fixed structures 11 are combined into a complete set of fixed modules, strengthening the stability of the entire internal floating roof. Additionally, eight symmetrically arranged counterweights 9 are arranged below the floating plate, making the internal floating roof float more stably in the oil tank, having a larger contact area with the oil surface, and reducing the risk of tipping over.
