Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 , the embodiment of the present invention provides a floating plate edge sealing device for a floating roof oil tank, which includes: a plurality of sealing slide plates 1 , sealing films 2 and support strips 7 .

[0023] Specifically, a plurality of sealing slide plates 1 are arranged in a ring shape along the circumference of the floating plate 5, and are located outside the edge of the floating plate 5. Any sealing slide plate 1 is composed of an upper section 11 and a lower section 12. The upper section 11 of the sealing slide plate 1 Bending towards the tank wall 6 of the floating roof oil tank, the top of the upper section of the sealing slide plate 1 is connected to the edge of the floating plate 5, the lower...

Abstract

The invention provides a floating disc edge sealing device of a floating-roof oil tank. The floating disc edge sealing device comprises a plurality of sealing sliding plates, sealing films and supporting strips. The sealing sliding plates are composed of upper segments and lower segments and sequentially arranged on the outer side of a floating disc in the peripheral direction of the floating disc so as to form a ring shape, the upper segments of the sealing sliding plates are bent towards the tank wall of the floating-roof oil tank, the top ends of the upper ends of the sealing sliding plates are connected with the edge of the floating disc, the lower segments of the sealing sliding plates are attached to the tank wall of the floating-roof oil tank, and the bottom ends of the lower segments of the sealing sliding plates are soaked into oil stored in the floating-roof oil tank. The sealing films are laid on the inner side faces of the sealing sliding plates. The supporting strips are located below the sealing films and used for supporting the sealing films so as to make the sealing films to be attached to the inner side faces of the sealing sliding plates, and the top ends of the supporting strips are connected with the edge of the floating disc. By means of the technical scheme, the floating disc edge sealing device has the advantages that active sealing performance is achieved, the compensation range is wide, and the sealing ability is high.

Description

technical field [0001] The invention belongs to the sealing field of floating-roof storage tanks in oil depot areas and storage tank areas in the petroleum and petrochemical industry, and in particular relates to a floating plate edge sealing device for floating-roof oil tanks. Background technique [0002] The floating plate in the floating roof oil tank is floating on the liquid surface of the oil tank and will rise and fall with the oil, so it is necessary to install a floating plate edge sealing device between the floating plate and the tank wall of the floating roof oil tank. [0003] In the prior art, the edge sealing device of the floating plate of the floating roof oil tank mainly has two types: bladder packing seal and mechanical shoe seal. There are two types of fillers for bladder packing sealing devices. One is to inject liquid (salt water, ethylene glycol, etc.) Free flow in the middle, so as to ensure the sealing of the rubber wear-resistant tape; the other is...
