Abstract

The invention relates to equipment for oil tanks. The goal is to increase reliability in work. The invention makes it possible to localize air bubbles under a floating coating and to ensure their effective discharge into the atmosphere. The support legs are hollow, with valves installed at their upper end sections. Racks fixed in glasses and have windows made in the wall for the passage of gases. Visors are made in the form of arcs and are located on the underside of the bottom. 5 il.

Description

The invention relates to equipment for oil tanks.

The purpose of the invention is to increase reliability in operation.

Equipping the floating pontoon of the tank with hollow pillars and valves on the upper end section, in combination with arcuate visors under the bottom, prevents the formation of air cavities under the pontoon and prevents the pontoon from falling and drowning.

FIG. 1 shows the constructive scheme of the tank with a floating coating; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. one.

A device to prevent the loss of petroleum products during storage is located in tank 1 and consists of an annular floating pontoon 2, bottom 3, a sealing gate 4 located along the perimeter of the pontoon 2, vertical hollow support columns 5, on the upper end section of each of which valve 6 is strengthened .

In the bottom 3, holes 7 are made, along the perimeter of which, glasses 8 are welded on the upper side of the bottom 3, in which support struts 5 are coaxially fastened. In the wall of each support stand 5 in the zone of placement of the cup 8 there are windows 9 for air passage. Somewhat below windows 9, spacer rings 10 are welded to the posts, in which holes II are made. Glasses 8 on top of the enclosures are closed from precipitation 12.

On the underside of the bottom 3, the visors 13 are reinforced, each of which has the shape of an arc and is located so that its concave side faces the receiving-dispensing nozzle 14, which is located horizontally under the bottom 3 in the wall of the tank 1.

The device works as follows.

The gases coming out of the pipe 14 when pouring oil from the pipe 14 are localized by visors 13 in the area of the support columns 5. Steam and air through the holes 7 and 1 1 in the bottom 3 in the spacer ring 10 enter the cavity of the glasses 8 and from there through the windows 9 into the cavity of the support columns.

When the pressure of the gases accumulated in the cavity of the rack 5 becomes sufficient to open the valve 6, the gases are released into the atmosphere.

In order to prevent oil from escaping, together with the escaping gases into the atmosphere, windows 9 are located above the level of oil installed in glass 8.
