Description

Closed oxygen-isolating and VOCs volatilization inhibiting device

Technical Field

The utility model relates to an oxygen-isolating sealing cover plate, in particular to a closed oxygen-isolating and VOCs volatilization inhibiting device for a storage tank.

Background

In modern industrial production, many liquid industrial products need to be stored in an oxygen-isolating way according to needs, and in order to achieve the purpose, a sealed oxygen-isolating device needs to be installed in a storage tank for use. The working principle is that the closed oxygen-isolating device floats on the liquid surface, and the outer edge of the closed oxygen-isolating device is in contact with the inner wall surface of the storage tank, so that the following sealing is realized.

The existing sealing oxygen-isolating device is simple in structure and has obvious defects in the aspect of inhibiting VOCs volatilization, and particularly, the existing oxygen-isolating device is of two structures, namely an intermediate soft material edge-added sealing capsule and an intermediate hard floating disc edge-added capsule, and the two structures are all insufficient. More specifically, the software separates oxygen device and forms the space easily between the liquid level, and then forms the volatilization of VOCs, and the hardware floating plate is single-layer structure, and the capsule on outer edge need be higher than the floating plate, and this can make and form the triangle clearance district between capsule and jar wall, and this region also is VOCs's main emergence place of volatilizing, and in addition, the floating plate is single-layer structure many, and itself has certain not enough in the leakproofness.

In conclusion, the closed oxygen-insulating device capable of effectively inhibiting volatilization of VOCs has great significance and application value.
