Description

Technical Field

[0001] The invention relates to the technical field of inner floating plates, in particular to a flexible piston servo electric direct-driven full-liquid-contact inner floating plate device for a storage tank. Background Art

[0002] The floating plate is an important device in the tank for storing large amounts of liquids (such as oil and chemicals). Its main function is to ensure the safety of the liquid stored in the tank, reduce liquid evaporation and environmental pollution, and provide controllable tank capacity. The floating plate is located above the surface of the liquid, forming a sealed space. When the liquid level in the tank rises or falls, the floating plate rises and falls with the liquid and always covers the liquid surface, thereby limiting the contact between the liquid and the atmosphere. This not only effectively reduces the evaporation of the stored liquid, but also prevents the entry of external impurities. Maintain the purity of the stored liquid. At the same time, the floating plate can prevent harmful gases (such as volatile organic compounds) from being released from the tank into the atmosphere, thereby reducing air pollution. In the event of an accident such as a fire, the floating plate can protect the combustion area of ​​the medium and effectively prevent the expansion of the combustion area. In addition, the modular parts of the floating plate are easy to make, transport, assemble, and install, which can greatly shorten the production cycle; it has large buoyancy, strong stability, strong anti-tilting and anti-jamming capabilities, and can meet the needs of multiple people walking on the floating plate. The floating plate has good anti-evaporation effect, medium compatibility and applicability for daily operations, making it the most widely used method for storing volatile liquid media.

[0003] The floating plate technology in the storage tank has been continuously improved and developed in the past few decades. At present, most of the floating plates put into use in my country are steel floating plates and aluminum floating plates. The floating plates of these two materials have their own advantages and disadvantages: the steel floating plate has better safety and environmental protection in the process of liquid storage, but there are certain deficiencies in meeting the production and operation needs; the aluminum floating plate meets the actual requirements of production and operation very well, but lacks in safety and environmental protection. With the continuous development of technology and the continuous enhancement of national environmental awareness, composite floating plates have emerged, which has brought the production and development of floating plates into a new stage. The composite floating plate uses glass fiber reinforced plastic instead of stainless steel and aluminum alloy. The composite floating plate can achieve full contact with the liquid, and the composite material has good corrosion resistance and durability, which meets the production environmental protection and safety requirements; at the same time, as a light floating plate, the composite floating plate can meet the production and operation needs very well, but the composite floating plate is expensive and cannot be put into production immediately.
