Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a high pressure autoclave with a pneumatic locking function. Background Art

[0002] An autoclave is a reactor that operates under high pressure. According to the process requirements, there are two types of autoclaves: one with an agitator and the other without an agitator. The structure of the former is the same as that of the stirring equipment. Its structural features are: (1) The autoclave body is a high-pressure cylinder with a thick shell. In order to be resistant to high temperatures and corrosion, it is usually made of stainless steel. Carbon steel or low-alloy steel is also used as the outer shell. Stainless steel is the inner layer material and can be made directly of composite plates or linings; (2) There are generally no holes on the autoclave body, and the pipes, interfaces and accessories are all installed on the autoclave cover; (3) The top of the autoclave is equipped with a safety relief device, such as a safety valve, a bursting disc device or a combination of the two.

[0003] After searching, I found an autoclave with application number: CN202020297989.8;

[0004] The utility model relates to the technical field of high-pressure equipment, and provides a high-pressure autoclave, comprising a control system, an autoclave body, a first mechanical pump, a second mechanical pump, a first air pump, a second air pump, and a valve structure. The interior of the autoclave body comprises a first cavity and a second cavity, the inlet of the first mechanical pump is connected to the first cavity, the inlet of the second mechanical pump is connected to the second cavity, the inlet of the first air pump is connected to the first cavity through a first pipe, the outlet of the first air pump is connected to the second cavity through a second pipe, the inlet of the second air pump is connected to the second cavity through a third pipe, the outlet of the second air pump is connected to the second cavity through a fourth pipe outlet, and valve structures are installed on both the first pipe and the third pipe. The utility model provides a high-pressure autoclave, which prevents the hot air in the autoclave from being lost in vain during the exhaust stage, thereby reducing the waste of heat sources.

[0005] Conventional autoclaves generally have the problem that the airtightness of the end cover of the autoclave body is not tight. Because it is under high pressure, it is necessary to achieve an automated sealing operation. The manual door closing operation obviously has a greater risk than the locked door sealing operation. The risk lies in manually closing the door. Obviously, this process has the risk of sudden opening due to the influence of gas pressure, so automated door closing and automated locking operations are very necessary. Utility Model Content

The design of the automatic closing and opening cabin has a geometric improvement in safe use. The edge seal of the surface cover prevents leakage when the high-pressure gas is contained in the autoclave and prevents it from collapsing when the cabin door is opened, thereby improving safety during use.
