Description

Technical Field

[0001] The utility model relates to the technical field of electrothermal digestion, and more specifically, to an electrothermal digestion device for plants for oxidative decomposition. Background Art

[0002] The wet ashing method is a chemical sample pretreatment method, which mainly digests the sample by adding strong oxidants (such as concentrated nitric acid, perchloric acid, etc.) to convert the substance to be measured into an ionic state and store it in the solution. A digestion instrument is a commonly used sample pretreatment device. When in use, the object to be digested is placed in a test tube located in a digestion hole, and the heat preservation liquid is heated by the digestion instrument to digest the object to be digested.

[0003] In the prior art solution, when taking and placing the test tube, since the test tube is heated and the surface temperature is relatively high, direct handling may scald the operator. And after the digestion of the digestion substance is completed, the test tube needs to be cleaned to avoid the interference of substance residues on the subsequent digestion work.

[0004] Chinese Patent with the patent application number CN202121367324.0 discloses an electrothermal digestion instrument, which includes a digestion instrument body, a plurality of test tubes and a lifting plate. A plurality of digestion holes are provided on the digestion instrument body. The test tubes are located inside the corresponding digestion holes. A baffle is installed on the test tube, and a fixing ring is connected to the test tube. For this electrothermal digestion instrument, the fixing ring is clamped by a clamping component, so that the fixing ring and the lifting plate can be connected. Through the lifting plate, the corresponding test tube can be lifted and transported. Compared with the above prior art, this solution is convenient for taking and placing the test tube, and can effectively avoid scalding the operator. By removing the baffle, the cleaning component can be inserted into the inside of the test tube, and the driving mechanism can drive the cleaning component to rotate to clean the inside of the test tube.

And when placing the test tube, it is inconvenient to fix the test tube, which affects the stability of the test tube placement and the use effect. Summary of the Utility Model
