Description
Technical Field
The utility model belongs to the technical field of chemical analysis sample is cleared up. In particular to a sample dissolving tank capable of cooling a tank cover.
Background
Fluoroplastics include Polytetrafluoroethylene (PTFE), perfluoro (FEP) copolymer, Polyperfluoroalkoxy (PFA) resin, etc., and are widely used in the technical field of chemical analysis sample digestion due to its high and low temperature resistance and chemical inertness. The fluoroplastic material has the characteristics of acid resistance, alkali resistance and various organic solvents resistance, is almost insoluble in all solvents, has the characteristic of high temperature resistance, can resist the high temperature of 300 ℃ in a short time, can be continuously and practically used at the temperature of 240-260 ℃ generally, and has remarkable thermal stability. Therefore, the material is widely used in the field of chemical analysis sample digestion, is made into a digestion bottle, a sealing digestion lining, a reaction kettle liner and the like, and is mainly used for heating a sample subjected to simple sample pretreatment and easy digestion treatment and a simple wet digestion experiment.
When some experiments need sealing, because of sealing heating, a certain pressure is generated in the bottle body at a high temperature, and the bottle body is easy to deform, the use temperature is not too high during sealing, and is controlled within 130-160 ℃. People adopt a method of adding a sleeve outside a closed container to improve the use temperature. If a stainless steel sleeve is additionally arranged, impurities such as iron and the like are easily introduced; the microwave digestion instrument with the additional reinforced plastics can be expensive.
The COD digestion bottle appears in the market, the digestion bottle body is increased to 20cm, the heated bottle bottom is longer than the bottle opening, and the deformation caused by overhigh temperature of the digestion cover is reduced by air cooling. The bottle body can be long, a support is needed, otherwise the bottle body is unstable, and the operation is troublesome.
Disclosure of Invention
An object of the utility model is to overcome the not enough of current design, provide a fluoroplastics cold top dissolves appearance jar, can satisfy the experiment and need airtight heating to dissolve the processing sample, can direct heating on the electric plate, the inside excessive pressure that can not produce of can body under the high temperature can avoid leading to airtight jar sealed inefficacy because of warping.
The utility model discloses a realize through following technical scheme: the utility model provides a fluoroplastics cold top dissolves appearance jar, includes can body and cover, is equipped with connecting thread, its characterized in that between cover and the can body upper portion: and a cooling container is arranged at the top of the tank cover.
The technical solution of the utility model in the cooling container be uncovered formula cooling container.
The technical solution of the utility model is that the cooling container and the tank cover are of an integral structure.
The technical solution of the utility model is that the outer diameter of the cooling container is the same as the outer diameter of the tank cover.
The height of the cooling container in the technical solution of the utility model is 5-15 mm.
The technical solution of the utility model is that the tank body and the tank cover are made of fluoroplastic.
The technical solution of the utility model is that the fluoroplastic is polytetrafluoroethylene, perfluorocopolymer or polyperfluoroalkoxy resin.
The volume of the can body in the technical solution of the utility model is 3-100 ml.
The ratio of the diameter of the pot body to the height of the pot body in the technical solution of the utility model is 1: 0.5-2.
The utility model discloses owing to on the sample jar basis is dissolved by can body and cover constitution now, be equipped with cooling container at the cover top, therefore during the experiment, add the can body with sample and reagent earlier, screw up the cover again, then toward cooling container injected water after, can directly put and heat and dissolve on being less than 300 ℃ of electric plate.
The utility model has the characteristics of do not change can body structure and height, make the sealed effectual of connecting thread through the cooling cover, the appearance jar that dissolves that mainly used chemical analysis sample was cleared up.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a can lid; 2. a can body; 3. a sample and a reagent; 4. connecting threads; 5. the vessel is cooled.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the present invention relates to an embodiment of a fluoroplastic cold top sample dissolving tank, which comprises a tank body 2 and a tank cover 1.
The structure and the height of the tank body 2 are the same as those of the existing sample dissolving tank. The upper part of the can body 2 is provided with a connecting thread 4.
The lower part of the tank cover 1 is the same as the tank cover of the existing sample dissolving tank. The inner wall of the lower part of the tank cover 1 is provided with a connecting thread 4 which is matched with the connecting thread 4 of the tank body 2, and the sample dissolving tank can be sealed when being screwed down.
The upper part of the can cover 1 is provided with a cooling container 5. The cooling container 5 and the can cover 1 are of an integral structure, and the outer diameter of the cooling container 5 is the same as that of the can cover 1. The cooling container 5 is an open cooling container. The height of the cooling vessel 5 is 10 mm, and may be selected from the range of 5 to 15mm as required.
The material of the can body 2 and the can cover 1 is polytetrafluoroethylene, and fluorine plastics such as perfluoro copolymer or poly perfluoro alkoxy resin can also be adopted.
The volume of the can body 2 is 3-100 ml. The ratio of the diameter of the can body 2 to the height of the can body is 1: 0.5-2.
