Description

Technical Field

[0001] This utility model relates to the technical field of moisture detection equipment, and more specifically, to a high-precision moisture analyzer. Background Technology

[0002] In the production, processing, quality control, and scientific research of numerous industries, sample moisture content and the impact of temperature and humidity changes on moisture content are two key detection indicators. The former directly relates to product quality, shelf life, and process parameter settings, while the latter is of great significance for optimizing material storage conditions and assessing environmental adaptability. Currently, the traditional method for measuring the moisture content of samples under temperature and humidity changes typically involves placing the sample in a constant temperature and humidity chamber, setting specific temperature and humidity conditions, and calculating the change in moisture content by measuring the change in sample mass. This process relies on an electronic balance for accurate weighing.

[0003] However, traditional measurement methods have many unsolvable problems in practical operation, which seriously affect the detection efficiency and accuracy: Firstly, there is the challenge of zero-point adjustment for electronic balances. As a core tool for mass measurement, electronic balances must be zero-point adjusted (calibrated) before use. However, because the measured values ​​of electronic balances are easily affected by environmental factors and drift, recalibration is required before each measurement.

[0004] Secondly, there is the issue of adapting the zero-point adjustment environment within the constant temperature chamber. To reduce external environmental interference, some solutions consider placing the electronic balance inside the constant temperature chamber. However, zero-point adjustment must be completed when the measuring platform (the tray on which the sample is placed) is free of sample weight. In a closed constant temperature chamber, precise control of sample placement and removal, as well as the empty state of the measuring platform, is extremely difficult. The operation is cumbersome and can easily disrupt the stable temperature and humidity environment inside the constant temperature chamber, further affecting subsequent measurements.

[0005] Third, the interference of airflow in the constant temperature chamber on the measurement. The constant temperature chamber needs to circulate air that has been adjusted to the set temperature and humidity to maintain environmental stability. However, the wind pressure generated when the airflow blows towards the measuring platform will directly interfere with the zero-point adjustment of the electronic balance, resulting in calibration deviation. Even after calibration is completed, the continuous airflow during the measurement process will still affect the weighing accuracy and distort the sample mass change data.

[0006] Fourth, the inherent defects of existing drying-based moisture analyzers. Commercially available drying-based moisture analyzers not only struggle to achieve efficient zero-point calibration of electronic balances within a constant-temperature chamber, but also cannot avoid the interference of airflow on the measurement.

[0007] Against this backdrop, there is an urgent need for a technology that can solve the problems of cumbersome zero-point adjustment and airflow interference in traditional measurements, and achieve efficient measurement of sample mass changes in a constant temperature chamber. This utility model of a high-precision moisture analyzer is therefore proposed. Utility Model Content

[0021] Furthermore, such as Figure 1 As shown, in this embodiment, the lifting mechanism includes a pair of drive cylinders 4. The output ends of the pair of drive cylinders 4 are fixedly connected to both ends of the lifting platform 3, and can drive the lifting platform 3 to rise and fall.

[0022] Furthermore, such as Figure 1 As shown, in this embodiment, it also includes: platform 5, and electronic balance 6 is installed on platform 5.

[0023] Furthermore, such as Figure 1 As shown, in this embodiment, platform 5 is a shock-absorbing platform 5, which reduces the impact of vibration on the electronic balance 6.
