Description

The utility model relates to floating roofs (or pontoons) of reservoirs for storing oil or oil products.

Analogs are known - floating roofs or pontoons of tanks for storing oil or oil products, containing flooring, beams, cylindrical shell, floats, support stands (see, for example, descriptions of inventions to patents RU 2127216, IPC 6 B 65 D 88/34, publication date 1999.03.10; RU 2137689, IPC 6 B 65 D 88/34, publication date 1999.09.20; RU 2111910, IPC 6 B 65 D 88/34, publication date 1998.05.27; RU 2211791, IPC 7 B 65 D 88 / 34, publication date 2003.09.10).

The disadvantage of analogues is the design complexity due to the presence of floats and permanently fixed vertical struts.

The closest analogue to the proposed utility model is the pontoon of the Tank with a pontoon for storing volatile oil products, containing a floor that hermetically covers the surface of the oil products, consisting of parallel strips, the edges of which are sandwiched between the longitudinal lower beams and the longitudinal upper beams, a peripheral ring (see, for example , description of the invention to the patent of the Russian Federation 2211791, IPC 7 B 65 D 88/34, publication date 2003.09.10).

The disadvantage of the closest analogue is the presence of floats, due to the insufficient buoyancy of the pontoon, leading to a complication of the structure as a whole, including the need for vertical racks permanently fixed to the bottom of the pontoon, and difficult maintenance of the pontoon. In addition, the presence of floats contributes to the formation of gas bubbles under the pontoon.

The technical result of the claimed utility model is to simplify the design, increase buoyancy, increase the strength of the flooring, increase the ease of maintenance of the floating roof of the tank.

The technical result is achieved in that the peripheral ring is made in the form of a channel, the lower shelf of which is fixed between the ends of the upper shelves of the longitudinal lower beams and the lower shelves of the longitudinal upper beams, and the middle part is attached by means of an annular angle to the upper shelves of the longitudinal upper beams on which the transverse channels are installed , the walls of which are attached by means of an annular corner to the middle part of the peripheral ring, on the upper part of the flooring is a layer of polyurethane foam with a full-fill height eniya space above the deck not more than

the upper edges of the shelves of the transverse channels, and on the upper surface of the layer of polyurethane foam applied a thin layer of protective insulating polyurethane foam.

The floating roof of the tank for storing oil or oil products, contains a floor that hermetically covers the surface of the oil or oil products, consisting of parallel strips 6, the edges of which are sandwiched between the longitudinal lower beams 3 and the longitudinal upper beams 2, the peripheral ring 1 (Fig. 1, 2, 3). The clamping of the edges of the strips 6 is carried out with rivets 8 and bolted joints 7 (Fig.3, 4). The peripheral ring 1 is made in the form of a channel, the lower shelf of which is fixed between the ends of the upper shelves of the longitudinal lower beams 3 and the lower shelves of the longitudinal upper beams 2 with bolted joints 7 (Figs. 3, 4). The middle part of the peripheral ring 1 is attached by means of an annular angle 5 to the upper shelves of the longitudinal upper beams 2 with rivets 8 (Figs. 3, 4). On the upper shelves of the longitudinal upper beams 2 installed and bolted 7 transverse channels 5 (Fig.7,

8). The walls of the transverse channels 4 are attached by means of an annular angle 5 to the middle part of the peripheral ring 1 with rivets 8 (Figs. 5, 6). On the upper part of the strips of flooring 6 there is a layer of polyurethane foam 13 with a height of full filling of the space above the strips of flooring 6 not higher than the upper edges of the shelves of the transverse channels 5 (Fig. 10, 11). On the upper surface of the layer of polyurethane foam 13 applied a thin layer of protective insulating polyurethane foam 14 (figure 10, 11).

To exit the gas from under the strips of flooring 6, the drain pipes 9 are fastened to the transverse channels 5 through gaskets 11 and to the longitudinal lower beams 3 by means of bolted connections 12 (Figs. 2, 7, 9). Drain pipes 9 may have a flange 10 in the upper part (Figs. 7, 9). The same drain pipes 9 serve to drain oil or oil products under the strips of flooring 6 if they fall onto the layer of protective insulating polyurethane foam 14 and onto the transverse channels 5.

Polyurethane foam 13 has an increased adhesive ability, is applied to the strips of flooring 6 in a liquid state, ensuring that a part of the surface of the peripheral ring 1, the surface of the longitudinal upper beams 2 and the transverse channels 5 are applied. After application, the polyurethane foam layer 13 hardens. Due to the strong adhesion of the polyurethane foam layer 13 to the flooring strips 6, the strength characteristics of the flooring strips 6 are significantly increased, while the lower surface of the flooring strips 6 retains its flatness during the entire operating time and reduces the possibility of gas bubbles forming under them. Filling the space above the strips of the flooring 6 with a layer of polyurethane foam 9 ensures buoyancy when oil or oil products stored in the tank fall onto the top of the floating roof due to the positive buoyancy of the polyurethane foam. Application of a thin layer of protective insulating polyurethane foam 14 to the polyurethane foam layer 13 provides protection against destruction of the polyurethane foam layer 13 when any substances act on the top of the floating roof. The floating roof should be equipped with a sealing shutter, for example, made of flexible polyurethane attached to the outer side of the peripheral ring 1.

The above data confirms compliance with the patentability criterion of industrial applicability.

When performing patent research, no distinguishing features of the claimed floating roof of the tank for storing oil or oil products were found among similar roofs or pontoons of tanks for storing oil or oil products, which confirms compliance with the patentability criterion of novelty.
