Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for a pressure vessel. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. Pressure vessels are widely used. They play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used in process such as heat transfer, mass transfer, reaction, and storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fields, such as air compressors. Various types of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are all pressure vessels.

[0003] A pressure vessel rust removal device disclosed in publication number CN216228662U, although the utility model is provided with a first connecting rod, rust-absorbing cotton, a second connecting rod, and a rust-removing brush, to solve the problem that after long-term use, rust easily forms on the surface of the existing pressure vessel, resulting in an unsightly appearance of the pressure vessel. By combining the above structures, the rust generated on the surface of the pressure vessel can be removed by the rust-absorbing cotton and the rust-removing brush after long-term use of the pressure vessel.

[0004] However, this pressure vessel rust removal device has the following disadvantages:

[0005] (1) When the staff uses the rust removal device, since there may be serious rust inside the pressure vessel, the rust removal device is not convenient for repeatedly removing rust from the inside of the pressure vessel, which reduces the rust removal effect of the rust removal device;

[0006] (2) When the staff uses the rust removal device, since different types of pressure vessels have different sizes, the device is not convenient for rust removal on pressure vessels of different sizes, which reduces the applicability of the rust removal device. Utility Model Content
