AI Technical Summary

Technical Problem

The floating plate of existing internal floating roof tanks is prone to getting stuck and having poor sealing performance during operation. In addition, the oil fluctuates irregularly during transportation, resulting in increased evaporation losses and safety hazards.

Method used

A floating plate inside a storage tank is designed, including a hollow cover and an air bag. The height of the floating plate and the volume of the air bag are adjusted by a driving mechanism and a charging and suction mechanism. A pressure sensor and a controller are combined to perform sealing detection to ensure that the floating plate is always close to the liquid surface and improve the sealing performance.

Benefits of technology

Effectively reduce evaporation loss, improve the sealing and stability of the floating plate, reduce oil shaking during transportation, and reduce friction loss and safety risks.

Abstract

The present invention relates to the technical field of floating plates inside storage tanks, and proposes a floating plate inside storage tanks and a detection device thereof, comprising: an inner floating plate body, a driving mechanism and a screw rod. Under the joint action of an upper pressure sensor, a lower pressure sensor, the driving mechanism and a controller, the height of the inner floating plate body can be automatically adjusted according to the height of the oil product, which can greatly reduce the evaporation loss of the stored material. Moreover, when the oil product inside the tank body is at a stable depth, the inner floating plate body remains stationary, which is convenient for providing stability to the oil product during transportation, can suppress the shaking of the oil product, and reduce the peak impact force. A charging and suction mechanism is provided on the hollow cover, and the charging and suction mechanism can be used to inflate and deflate the interior of the airbag and change the volume of the airbag, which can reduce the friction loss when the airbag slides and improve the sealing performance of the airbag when it is stationary. A detection mechanism is provided inside the tank body, and in cooperation with the charging and suction mechanism, it can detect the sealing performance of the airbag under different states.
