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.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a closed oxygen-insulating device for a storage tank, which can effectively inhibit the volatilization of VOCs.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: the closed oxygen-isolating and VOCs volatilization inhibiting device comprises a body, an upper sealed capsule and a lower sealed capsule, wherein the upper sealed capsule and the lower sealed capsule are annular, and are arranged up and down and are arranged on the outer edge surface of the body; the body comprises an annular outer frame, an inner support frame, an upper oxygen-isolating membrane, a lower oxygen-isolating membrane, an upper capsule support and a lower capsule support; the inner support frame is arranged in the annular outer frame and used for radially supporting the annular outer frame; the lower oxygen-isolating membrane is arranged on the bottom surface and the side surface of the annular outer frame and used for sealing the opening and the side surface of the bottom surface of the annular outer frame, the upper oxygen-isolating membrane is arranged on the top surface of the annular outer frame and used for sealing the top surface of the annular outer frame, and the lower oxygen-isolating membrane are used for integrally coating and sealing the annular outer frame; the upper capsule supports are annularly distributed on the upper edge of the annular outer frame, are matched with the upper sealing capsules and are used for fixing the upper sealing capsules; the lower capsule supports are annularly distributed on the lower edge of the annular outer frame, are matched with the lower sealing capsules and are used for fixing the lower sealing capsules.
Furthermore, a plurality of connecting pieces are arranged on the inner support frame, and each connecting piece extends out of the upper oxygen-isolating film.
Further, the body is provided with at least one air valve, the bottom end of the air valve extends out of the lower oxygen-isolating membrane, and the upper end of the air valve extends out of the upper oxygen-isolating membrane.
The utility model realizes the sealing of the body by two layers of oxygen isolating films to form a two-layer sealing structure, and realizes the two-layer sealing of the edge by the upper sealing capsule and the lower sealing capsule, thereby effectively inhibiting the volatilization of VOCs and better realizing the oxygen isolating sealing.
