Problems solved by technology

However, if the calorimeter is changed to a clamshell design, there will be a series of problems: due to the rotation deviation of the hinged lid every time it is opened and pressed down, the buckle position and the protruding volume of each clamshell will change. The deviation will eventually lead to inaccurate constant volume of the inner barrel of the calorimeter, seriously affecting the accuracy of each test
At the same time, the sealing performance of the clamshell snap-fit ​​design is also very difficult. Due to the rotation deviation, it is easy to have a sealing blind spot, resulting in the leakage of the inner barrel test water, which not only seriously affects the test accuracy, but also may cause test accidents.

Abstract

The invention discloses an automatic calorimeter for analysis of a sample calorific value. The automatic calorimeter comprises an outer barrel and an inner barrel, and also includes a flip cover device for sealing the outer barrel and the inner barrel, the flip cover device comprises a flip cover body and a constant volume cover fixed on a flip cover body seal surface, the constant volume cover is in flexible connection with the flip cover body through an installation component, the upper end in the inner barrel is equipped with a sealing limit piece that cooperates with the constant volume cover to seal the inner barrel, during operation, the flip cover body drives the downward flip of the constant volume cover, and after sealing of the constant volume cover by the sealing limit piece, the flip cover body further presses to complete sealing covering. The automatic calorimeter provided by the invention has the advantages of simple and compact structure, convenient and rapid operation of flip cover design, high precision of constant volume and good sealing performance.

Description

technical field [0001] The invention mainly relates to the field of sample analysis instruments, in particular to an automatic calorimeter used for calorific value analysis of samples. Background technique [0002] For the laboratory analysis of material (such as ore, coal) samples, each country has mandatory standards, which must be followed. For example, taking the analysis of coal samples as an example, the principle of the sample analysis process is to conduct relevant analysis on the samples that meet the requirements without destroying the representativeness of the samples. The accuracy of the analysis, so that the test results can reflect the characteristics of the sample most truly. [0003] In the laboratory analysis of material (such as ore, coal) samples, it is often necessary to use a calorimeter to analyze the calorific value of the sample. Existing calorimeters often have the following technical problems: [0004] 1. The existing calorimeter adopts the lifti...
