Description

Technical Field

[0001] The utility model belongs to the technical field of digestion tanks, in particular to a hollow buckle anti-corrosion and high-efficiency sample dissolving digestion tank. Background Art

[0002] In recent years, with the development of testing and analysis technology, especially the widespread application of AAS, ICP-OES and ICP-MS, the sample digestion technology has made rapid progress.

[0003] There are many digestion methods at present, and there are four digestion methods that are widely used: 1. Open sample dissolution in a polytetrafluoroethylene crucible. This method uses a large amount of acid, has a high blank, and is prone to external contamination; 2. Sealed digestion in an ordinary digestion tank. This method is mainly electric hot plate digestion, with uneven temperature and low pressure resistance. In the digestion of biological samples and geological samples, it causes incomplete digestion and affects the precision and accuracy of the test; 3. Microwave digestion technology. This technology has developed particularly rapidly, but its shortcomings are also obvious. The operation is complicated and cumbersome, the amount of acid used is large, and the subsequent treatment is relatively complicated. The digestion of biological and geological samples is unstable, and incomplete digestion often occurs. The safety is not high. It controls the temperature and pressure through temperature and pressure sensors. In actual operation, explosions often occur; 4. High-pressure reactor is a technology widely used in inorganic digestion in the last century. It has significant advantages. It can completely digest biological samples and geological samples and the test data is accurate. However, there are also some problems, such as the acid is easy to leak. Due to the volatilization of the acid, the sample digestion is incomplete, the experiment fails, and the stainless steel tank body is corroded. There are some safety hazards and potential pollution. At the same time, the traditional digestion tank adopts a screw buckle interface. The whole tank body is screwed together and sealed. The operation time is long and the operation is cumbersome, which consumes a lot of time and physical strength of experimental technicians. In this regard, the utility model designs a hollow buckle anti-corrosion and high-efficiency sample dissolution digestion tank to solve the above problems. Utility Model Content

The product becomes the final product of steel-lined digestion tank.

[0012] The utility model adopts a double inner concave design in the designed tank body.
