Description

Technical Field

[0001] The utility model relates to the technical field of oil floating roof storage tanks, in particular to an oil floating roof storage tank with a double-layer sealing structure. Background Art

[0002] The floating roof of a floating roof tank is a floating plate that floats on the surface of the liquid in the tank and rises and falls with the rise and fall of the liquid level in the tank. Seals are provided on the edges of the floating plate. The floating roof tank uses seals to isolate the liquid in the tank from the outside atmosphere, thus preventing the liquid in the tank from reacting with oxygen in the atmosphere.

[0003] However, most of the existing oil floating roof storage tanks are not equipped with guide columns, which causes the floating plate to shake easily during the lifting process and is not stable enough; at the same time, the sealing performance between the floating plate and the storage tank inside the existing oil floating roof storage tank is poor, which makes the oil easily affected by external oxygen during storage, accelerating the oxidation and deterioration of the oil. Utility Model Content

[0006] As a further improvement of the present invention, the first flexible sealing plate is installed at the edge of the floating plate through a plurality of first bolts, and the plurality of first bolts are distributed in a ring array about the center of the floating plate.

[0007] As a further improvement of the present invention, the cross section of the first flexible sealing plate is U-shaped, and the outer periphery of the first flexible sealing plate is interference fit with the inner wall of the storage tank body.

[0008] As a further improvement of the present invention, the second flexible sealing plate is mounted on the first flexible sealing plate through a plurality of second bolts, and the plurality of second bolts are distributed in a circular array about the center of the floating plate.

[0009] As a further improvement of the present invention, the outer periphery of the second flexible sealing plate is interference fit with the inner wall of the storage tank body.

[0010] As a further improvement of the utility model, the third flexible sealing plate is installed on the periphery of the guide opening of the floating plate through a plurality of third bolts, and the plurality of third bolts are distributed in a ring array about the center of the guide opening.

[0011] As a further improvement of the present invention, the cross section of the third flexible sealing plate is U-shaped, and the inner periphery of the third flexible sealing plate is interference fit with the guide column.

[0012] As a further improvement of the utility model, a fixed base is provided at the bottom of the storage tank body, and a guardrail mechanism and a ladder mechanism are provided at the top of the storage tank body.

[0013] The beneficial effects of the utility model are as follows: a guide column is arranged inside the storage tank body of the utility model, so that the floating plate can rise or fall stably, avoiding the floating plate from shaking during the lifting process, thereby improving the lifting stability of the floating plate; at the same time, a two-layer sealing structure is arranged between the edge of the floating plate and the inner wall of the storage tank body, and a sealing structure is arranged between the floating plate and the guide column, which can improve the sealing performance of the floating plate, avoid the oil product from contacting with the outside world and causing the oil product to oxidize and deteriorate, thereby ensuring the quality of the oil product.
