Description

Anti-reverse-rotation digestion tank

Technical Field

The utility model relates to a technical field is cleared up to indissolvable mineral specifically is a prevent jar of clearing up of derotation.

Background

In the research of the earth science, the rare earth elements are a group of elements which have similar chemical properties and are difficult to separate, are often closely symbiotic and are not easily interfered by the weathering effect, the hydrothermal alteration effect and even certain metamorphic effects, can be easily preserved once being recorded in a geological body, and have the meaning of the geochemical effect. The difference of the physical and chemical properties of different rare earth elements, especially the difference of the mass, leads to the differentiation of the rare earth elements under the action of the earth gravitational field, and can further track and discuss the formation and development of various geologic bodies (mantle, crust, rock, deposit and mineral). The abundance and distribution of rare earth elements within various geological bodies has therefore become an extremely useful tool for studying the formation and evolution of these geological bodies.

Iridium (Ir), ruthenium (Ru), rhodium (Rh), platinum (Pt), palladium (Pd) and gold (Au) in platinum group elements, wherein the platinum group elements have certain regularity in the distribution mode of the platinum group elements in various geological bodies, and the geological bodies always inherit partial characteristics of parent bodies; the elements are respectively in the fifth period and the sixth period, and are in oxidation states from left to right along a chemical periodic table from bottom to top, the melting point and the boiling point are gradually reduced, and the difference of physical and chemical properties causes the elements to have different degrees in the geological evolution process, so that the distribution modes of the elements in different geological bodies have characteristics.

The analysis of these elements currently relies on conventional wet analysis. The wet analysis comprises the following main processes: firstly, dissolving a geological sample (powder sample) into liquid by using aqua regia or nitric acid and then adding a strong acid medium such as hydrofluoric acid and the like under a heating state, and then carrying out quantitative analysis by using ICP-Ms.

In order to ensure the digestion of insoluble minerals, a sample dissolving tank is mainly adopted for high-temperature high-pressure digestion at present. The sample dissolving tank mainly comprises a stainless steel outer sleeve (coated with a Teflon coating) and a polytetrafluoroethylene inner container. Dissolve appearance jar and also clear up jar, traditional jar of clearing up, the following problem exists in most:

1. when carrying out high temperature high pressure and clear up, the stainless steel enclosing cover is not hard up easily, and the stainless steel overcoat that screws up promptly is when heating, because the inner bag has born high temperature high pressure, and easy inflation leads to the stainless steel enclosing cover not hard up, the back spin. Taking rare earth and trace elements analysis as an example, after a sample and acid are added into the inner container, the inner container needs to be filled into a stainless steel jacket, and the sample and the acid are digested for 7 days and nights in an oven at 200 ℃. And (4) after digestion, taking out the digestion tank from the oven, wherein most stainless steel covers of the digestion tank are loosened. As a result of the loosening, the acid in the inner container leaks, corrodes the oven (the oven is made of steel), and easily contaminates the sample. Meanwhile, the pressure of a digestion system is reduced due to the fact that the stainless steel cover is loosened, so that the dissolving efficiency of part of indissolvable minerals is reduced, and even the dissolution is incomplete.

2. The inner container adopts a compression sealing structure. In order to prevent leakage, must compress tightly, this leads to clearing up after, partial inner bag is very difficult to be opened (after the intensification, cool down again, pressure is the negative pressure in the inner bag), the difficulty has been brought for the staff, when opening the inner bag hard, the aqua regia that is used for clearing up in the inner bag and hydrofluoric acid etc. are all strong corrosive acid, spill easily, cause sample solution to lose, can not be used for the analysis, lead to the waste, acidic corrosive substance in the inner bag is in case infected with on one's body the staff simultaneously, will cause the injury of different degrees to the health, safety in utilization is lower.
