A storage tank with a corrosion-resistant structure

Abstract

This utility model relates to a storage tank with an anti-corrosion structure, including a tank body and a tank bottom plate. The tank bottom plate is fixed to a base, and the lower end of the tank body is welded to the tank bottom plate. The outer region of the tank bottom plate at the lower end of the tank body is an edge plate. A protective strip covers the edge plate. A water baffle is a conical structure, with its upper end welded and sealed to the tank body. The water baffle is located above the edge plate and shields the protective strip from above. This effectively protects the edge plate and protective strip of the storage tank, reduces the corrosion rate of rainwater on the bottom plate, and improves the service life of the edge protective strip.

Description

Technical Field

[0001] This utility model relates to a storage tank with a corrosion-resistant structure. Background Technology

[0002] The storage tank is a large tank used to store diesel, gasoline, etc. The tank is installed on a base and has high requirements for the sealing of its bottom. The tank includes an annular tank body and a bottom plate, with the bottom plate on the outer lower part of the tank body forming an edge plate. The bottom plate is fixed above the base, and a protective strip covers the edge plate to waterproof it.

[0003] During routine inspections, it was found that the protective strip at the bottom edge of the storage tank was severely damaged. Water accumulation at the damaged area accelerated the corrosion rate at the connection between the tank bottom plate and the tank body, i.e. corrosion occurred at the right angle at the bottom, thus affecting the sealing performance of the bottom of the storage tank.

[0009] The water baffle is a conical structure with its upper end welded and sealed to the tank body. The water baffle is located above the edge plate and shields the protective strip above it.

[0010] Furthermore, the protective strip includes a primer layer, a PE foam board, a first mesh fabric layer, a sealant, a second mesh fabric layer, and an outer protective sealing strip layer;

[0011] The primer layer is applied to the upper surface of the edge plate, the side surface of the edge plate, and the outer surface of the base.

[0012] The PE foam board is located on the outer side of the base;

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This application provides a storage tank with a corrosion-resistant structure, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0030] To address the technical problem of easy corrosion of the bottom edge plate of storage tanks in the prior art, one embodiment of this application provides a storage tank with an anti-corrosion structure. This is described in detail below.

[0031] like Figure 1 and Figure 2 As shown, a storage tank with a corrosion-resistant structure includes...

[0032] Tank body 1 and tank bottom plate 2, the tank bottom plate 2 is fixed on base 4, the lower end of the tank body 1 is welded to the tank bottom plate 2, and the tank bottom plate 2 in the outer area of ​​the lower end of the tank 1 is an edge plate;

[0033] Protective strip 5, which covers the edge plate;

[0034] The water baffle 3 has a conical structure, and its upper end is welded and sealed to the tank body 1. The water baffle 3 is located above the edge plate and shields the protective strip 5 from above.

[0035] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the protective strip 5 includes a primer layer 51, a PE foam board 52, a first mesh fabric layer 53, a sealant 54, a second mesh fabric layer 55, and an outer protective sealing strip layer 56.

[0036] The primer layer 51 is applied to the upper surface of the edge plate, the side surface of the edge plate, and the outer surface of the base 4.

[0037] The PE foam board 52 is located on the outer side of the base 4;

[0038] The first mesh fabric layer 53 covers the edge plate and the outside of the PE foam board 52;

[0039] The sealing putty 54 covers the outside of the first mesh fabric layer 53;

[0040] The second mesh fabric layer 55 covers the outside of the sealant 54;

[0041] The outer protective sealing strip layer 56 covers the outside of the second mesh fabric layer 55.

[0042] Specifically, as an optional implementation method in this embodiment, such as Figure 2As shown, both the first mesh fabric layer 53 and the second mesh fabric layer 55 are polyester spandex elastic mesh fabric layers.

[0043] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the distance between the lower end of the water baffle 3 and the protective strip 5 is 250mm.

[0044] In this embodiment, the primer layer 51 is one of butyl rubber modified asphalt primer, epoxy coal tar anti-corrosion primer, epoxy primer, and anti-rust paint. By applying the primer, the surface of the edge plate and the surface of the base 4 can be made denser, achieving rust prevention, and it also facilitates the coverage of the first mesh fabric layer 53.

[0045] In this embodiment, the PE foam board 52 serves as a buffer and support for the upper end of the base. The PE foam board 52 is located on the edge plate and the side of the base 4, thus protecting the upper corner of the base 4.

[0046] In this embodiment, the sealing putty 54 is made of petrolatum putty, which is also known as flexible grease fiber anti-corrosion sealant or flexible oil slope layer, and the petrolatum tape is also known as flexible grease fiber anti-corrosion sealant tape (with or without film).

[0047] In this embodiment, the outer protective sealing tape layer 56 adopts any of the following: polypropylene reinforced fiber anti-corrosion adhesive tape, cloth-based anti-corrosion adhesive tape, aluminum foil anti-corrosion adhesive tape, viscoelastic anti-corrosion tape, polyvinyl chloride anti-corrosion adhesive tape, polyethylene anti-corrosion adhesive tape, electrical adhesive tape, and butyl tape.

[0048] The construction process of protective strip 5 is as follows:

[0049] Now apply primer to the edge plate and the upper part of the base 4, then place PE foam board 52 on one side of the upper part of the base 4, and then roll up the first mesh cloth layer 53. After the first mesh cloth layer 53 is fixed, apply petrolatum putty to the surface of the first mesh cloth layer 53. After applying the putty, continue to roll up the second mesh cloth layer 55. After the second mesh cloth layer 55 is fixed, finally attach the outer protective sealing tape layer 56 to the surface.

[0050] By effectively protecting the edge plate and protective strip 5 of the storage tank, the corrosion rate of rainwater on the bottom plate is reduced, and the service life of the edge protective strip 5 is increased.
