Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection of liquefied gas cylinders, in particular to a pressurizing device suitable for an airtightness detection device of a liquefied gas cylinder. Background Art

[0002] Liquefied gas cylinders, also known as liquefied gas tanks, are storage tanks used to store liquefied gas. When there is liquefied gas inside, the pressure is very high. Any improper operation may cause an explosion. It is a special equipment. Before the liquefied gas cylinder leaves the factory, it needs to be tested for air tightness. First, the liquefied gas cylinder is inflated. After the inflation is completed, the liquefied gas cylinder is placed in a pool as a whole. By observing whether there are bubbles in the pool, it can be judged whether there are defects such as leakage. Usually, a pressurizing device is used during inflation to increase the inflation speed. The existing pressurizing device pressurizes the air through the spiral blades in the shell, but there is no filtering mechanism on the air inlet pipe, which will cause a large amount of impurities to accumulate in the shell, thereby affecting the normal operation of the spiral blades.

[0003] In the prior art, a Chinese patent document with publication number CN220168120U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: The present application discloses an air pressurizing device, which relates to the technical field of air pressurization, and comprises a shell, an outer wall of one side of the shell is provided with an air inlet, and the inner wall of the air inlet is fixedly connected with an air inlet pipe, the air inlet pipe is connected with a filter pipe through a pipeline, and one end of the filter pipe is fixedly connected with a cover plate, the inner wall of the filter pipe is rotatably connected with a mounting pipe, and the mounting pipe and the air inlet pipe are connected, the outer wall of the mounting pipe is provided with three openings distributed at equal distances, and the inner walls of the three openings are fixedly connected with dust filter cloths, and one end of the mounting pipe is provided with four clamping grooves distributed at equal distances.

[0004] In order to solve the problem that there is no filtering mechanism on the air intake pipe of the existing pressurized equipment, which will cause a large amount of impurities to accumulate in the shell, the existing technology adopts a filter tube, and a filter net and a dust filter cloth are set in the filter tube for processing. However, the pressurized equipment will generate high temperature after long-term use, which will easily affect the use and safety of the equipment, and will cause the pressurized air to heat up and affect the detection effect.
