Description

Technical Field

[0001] The present application relates to the technical field of storage tanks, and in particular to high-strength, corrosion-resistant, pressure-bearing storage tanks. Background Art

[0002] Storage tanks refer to equipment used to store various liquid raw materials, semi-finished products or finished products. Also known as "storage tanks". Due to the wide variety of storage media and the diversity of storage conditions, there are correspondingly different types of storage tanks. According to the material, they are divided into metal and non-metal storage tanks. Metal storage tanks are widely used, and non-metal storage tanks are mainly used to store media with corrosion resistance requirements and low pressure. According to the structural shape, they are divided into cylindrical, spherical and non-circular cross-section (such as oblong, rectangular) storage tanks. Cylindrical storage tanks are the most widely used because they are easier to manufacture.

[0003] At present, most of the existing storage tanks adopt the method of spraying a corrosion-resistant coating on the surface of the storage tank to increase the corrosion resistance of the storage tank. However, during the use of the storage tank, external objects may damage the corrosion-resistant coating on the surface of the storage tank, which will greatly reduce the corrosion resistance of the surface of the storage tank. Utility Model Content

[0004] Based on this, it is necessary to increase the corrosion resistance of the tank by spraying a corrosion-resistant coating on the surface of the tank. However, during the use of the tank, external objects may damage the corrosion-resistant coating on the surface of the tank, which will greatly reduce the corrosion resistance of the tank surface. In this paper, a high-strength corrosion-resistant pressure tank is provided.

[0005] The present application provides a high-strength, corrosion-resistant, pressure-bearing storage tank, comprising:

[0006] Tank;

[0007] A first protective component is configured to be cylindrical, the first protective component is sleeved on the outside of the tank body, the outer circumferential surface of the tank body at least partially abuts against the inner wall of the first protective component, and an anti-corrosion channel is formed between the first protective component and the tank body;

[0008] A second protective assembly is disposed on the top of the tank body, the bottom of the second protective assembly at least partially abuts against the top of the tank body, and the second protective assembly is fixedly connected to the top of the first protective assembly;

[0009] A third protection component is disposed at the bottom of the tank body, the top of the third protection component at least partially abuts against the bottom of the tank body, and the third protection component is fixedly connected to the bottom of the first protection component;

[0011] The second air nozzle is arranged on the third protection component, and the second air nozzle is connected to the bottom of the anti-corrosion channel.

[0012] The present application relates to a high-strength, corrosion-resistant, pressure-bearing storage tank, in which an anti-corrosion channel is formed by the inner wall of a first protective component and the outer circumferential surface of the tank body, and the top of the anti-corrosion channel is sealed by connecting a second protective component to the top of the first protective component, and then the bottom of the anti-corrosion channel is sealed by connecting a third protective component to the bottom of the first protective component, and then inert gas can be injected into the tank body through a first gas nozzle and a second gas nozzle respectively to change the environment of the tank body, thereby enhancing the corrosion resistance of the tank body. At the same time, the first protective component, the second protective component and the third protective component can also enhance the pressure resistance of the tank body.
