Abstract
The utility model relates to a measuring device for chemical oxygen demand (COD), specifically to a fully sealed microwave digestion tank. The utility model is made of polytetrafluoroethylene or modified polytetrafluoroethylene and consists of a tank body and a sealing cover. The tank and the sealing cover are connected through connection thread. Six indented antiskid concave strips are uniformly distributed on the sealing cover. The external surface of the tank bottom is spherical surface. Digestive solution and a sample are arranged in a digestive area. The utility model has the advantages of high temperature resistance, acid and alkali resistance and high microwave penetration rate. And the precision of the testing results can be assured and the requirements for measuring the chemical oxygen demand (COD) using microwaves can be satisfied.
Description
Technical field
The utility model relates to a kind of chemical oxygen consumption (COC) (COD) determinator, is a kind of hermetically sealed micro-wave digestion jar specifically.
Background technology
Chemical oxygen consumption (COC) (COD) is to weigh the important indicator of water quality, is the embodiment of water body organic contamination degree, uses very general.Traditional assay method adopts uncovered backflow to clear up assay method, not only spended time is long for this method, the consumption medicine is many, and aromatics is difficult to oxidation, and some be easy to volatile organism (as ether etc.) can not complete oxidation, thereby can not truly reflect the chemical oxygen consumption (COC) (COD) of sample.
Though existing micro-wave digestion jar can be used for carrying out micro-wave digestion,, cause test result inaccurate because the opening at gland bonnet top causes digestion solution and volatile organic compound to run off in sealed shell of tank.
The purpose of this utility model is the incomplete airtight problem that exists at existing microwave digestion technology, a kind of hermetically sealed micro-wave digestion jar is provided, not only can bear the internal pressure when clearing up organism, and guarantee that digestion solution and volatile organic compound do not run off, and guarantee the accuracy of measurement result in sealed shell of tank.
Description of drawings
Fig. 1 is hermetically sealed micro-wave digestion jar structure figure
Wherein: 1, tank body, 2, gland bonnet, 3, anti-skidding recessed, 4, connect screw thread, 5, inner sealing lid, 6, jar end, 7, clear up the district.
Embodiment
Hermetically sealed microwave seal jar as shown in Figure 1, adopt politef plastics or modification politef material to make, form by tank body 1 and gland bonnet 2, tank body 1 and gland bonnet 2 are by connecting screw thread 4 close-coupled, gland bonnet 2 outsides evenly distribute six recessed anti-skidding recessed 3, the outside ball-type that adopts in the jar ends 6, digestion solution and sample are positioned over to clear up in the district 7 to be cleared up.
There is inner sealing lid 5 gland bonnet 2 inside of hermetically sealed micro-wave digestion jar, closely contact with the top of tank body 1.
The profile of hermetically sealed micro-wave digestion jar is a right cylinder, the length of gland bonnet 2 is 40～50mm, diameter 55～60mm, reach top thickness all around at 5～10mm, the length of the tank body 1 of sealable tank is 90～110mm, diameter 45～50mm, wall and bottom sphere thickness are at 5～10mm, and capacity is at 65ml～150ml.The hermetically sealed micro-wave digestion jar of the utility model service pressure is at 2～3 atmospheric pressure, and temperature is about 180 ℃ in jar.And, can satisfy the needs that utilize micro-wave digestion to measure chemical oxygen demand (COD) (COD) because politef (or modification politef) has advantages such as high temperature resistant, acid-fast alkali-proof, microwave penetration rate height and good airproof performance.
Carry out chemical oxygen consumption (COC) (COD) when measuring, sample and digestion solution are positioned over to be cleared up in the district 7, and tank body 1 and gland bonnet 2 be by after connecting screw thread 4 close-coupled, utilize gland bonnet 2 and inner sealing lid 5 make whole sealable tank complete airtight after, put into micro-wave oven and clear up.
