Description
Technical Field
The invention relates to the technical field of laboratory vessel cleaning equipment, in particular to a cover body structure, an acid steaming cleaning device and an acid steaming cleaning method.
Background
With the popularization of ICP-MS, the lower detection limit value of the instrument is lower, and the blank value of a laboratory ware is required to be lower. The analysis of trace and ultra-trace metal elements in a laboratory requires that vessels used must be clean to avoid bringing pollutants into samples, and if the vessels are not clean, the background value is too high to influence the accuracy of experimental results.
Trace purging of CEM microwave digestion tanks typically requires the use of an acid-steaming purger to accomplish this. At present, most of the acid digestion cleaners on the market are designed to reversely buckle a microwave digestion tank C to be cleaned on a steam pipe 1a for cleaning as shown in fig. 1 (for example, the same is true of fig. 12 in chinese patent document CN105436166 a), and a notch a is arranged at the top end of the steam pipe 1a, so that the exhaust port of the steam pipe 1a can be prevented from being blocked by the bottom wall of the microwave digestion tank. However, since the contact part of the bottom wall of the microwave digestion tank and the top end of the steam pipe 1a is shielded, the contamination may remain in the contact part, and the reliability of the detection result is affected. In order to better ensure the cleaning effect, it is a common practice in the industry to rotate the microwave digestion tank at intervals during the acid steaming process to adjust the contact position of the microwave digestion tank and the steam pipe 1a, and thus the operation is very inconvenient. In particular, the contact position of the microwave digestion tank and the steam pipe 1a is adjusted manually, so that the situation that some parts are still shielded in the multiple adjusting processes is possible.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
In order to facilitate a clearer understanding of the concept of the invention for those skilled in the art, a more detailed description thereof will be given below with reference to the accompanying drawings. It should be noted that, for convenience of description, the vessels to be cleaned in the following examples are illustrated by using CEM microwave digestion tanks commonly used in laboratories.

As can be seen from the exploded structure shown in fig. 3-4, the greatest improvement of this embodiment over the conventional acid steaming cleaning device is the difference in the structure of the cover B. In general, the cover body B includes a body 2 covering the top opening of the washing chamber 1, and a gripping mechanism for gripping the outer circumferential surface of the CEM microwave digestion tank C inverted on the steam pipe 1a is provided at the inner side of the body 2, and in addition, an operating mechanism connected to the gripping mechanism is provided at the outer side of the body 2, and is configured to apply a force to the gripping mechanism, causing the gripping mechanism to grip the outer circumferential surface of the vessel to be cleaned and lift upward, so as to suspend the CEM microwave digestion tank C above the steam pipe 1 a.
