Description

Novel high-pressure digestion tank

Technical Field

The utility model relates to a jar technical field is cleared up to high pressure, concretely relates to novel jar is cleared up to high pressure.

Background

The high pressure digestion tank is also called pressure bomb, high pressure sample dissolving bomb, geological digestion tank, etc. and is one kind of closed container for digesting sample in chemical analysis. Under the high-temperature and high-pressure strong acid environment in the high-pressure digestion tank, a plurality of samples which are difficult to digest by the traditional method can be rapidly digested, the method is an effective tool for sample pretreatment, and the method is widely applied to the fields of geological chemistry, environmental science, biomedicine, material science and the like. The existing closed digestion tank adopts a mode that a sample dissolving cup is directly and tightly combined with each surface of an outer sleeve tank so as to improve the pressure in the tank in the digestion process. In recent years, with the rapid development of trace element research, the metal outer tank of the high-pressure digestion tank easily influences the sample in the sample dissolving cup when digesting the sample, so that the metal content in the sample is increased, and the experimental accuracy is influenced. The method adopted in the market is to add a layer of fluoroplastic sleeve between the sample dissolving cup and the outer tank for blocking. However, in practical application, when the sample dissolving cup and the sleeve are placed into the outer tank together, the cup body of the sample dissolving cup of the tight seal type is easy to rub against the inner wall of the sleeve, so that the cup cover of the sample dissolving cup is separated from the cup body, sample pollution is easy to cause, and experimental safety accidents are easy to cause due to the fact that strong base or strong acid is arranged inside the sample dissolving cup. If the sample dissolving cup adopts a rotary sealing type, after high-pressure digestion, the sample dissolving cup is inconvenient to open, a bottle cap needs to be twisted by great force, and the operation can easily cause acid liquor in the bottle to spill out, so that the loss of a sample, an experiment safety accident and other serious consequences are caused.
