Description
Technical Field
The utility model relates to the technical field of analyzers, in particular to an electronic balance for a pressure type fine soil particle analyzer.
Background
The existing fine soil particle analysis method mainly comprises the following steps: pipette method and hydrometer method. The hydrometer method is mainly designed according to the Archimedes principle and the Vaccinium uliginosum principle, and has the advantages of simple operation and low experimental cost; the disadvantages are as follows: 1. during the test, the insertion of the hydrometer can cause soil particles to generate ascending movement between the measuring cylinder wall and the bulb wall of the hydrometer (which has the law of violation of the Vaccinium uliginosum period), and the accuracy of the experiment is influenced. 2. The shoulder of the bulb body of the hydrometer can be partially adsorbed by soil particles, so that the weight of the hydrometer is increased, and the experimental precision is influenced. The hydrometer method has the defects, and is popularized, because the hydrometer method is proposed for over one hundred and seventy years, and the current testing means and technology are advanced. The pipette method is mainly designed according to the Vaccinium uliginosum theorem, sample liquid is extracted at a fixed time t and a fixed depth h according to the particle size of soil particles to be detected, and then the content of soil in the sample liquid is used for calculating a particle analysis result. The pipette method is obviously superior to the hydrometer method in terms of experimental methods, but the operation process is more complicated, and the sample liquid at the fixed depth h is not sucked in the operation process. When the pipette is inserted, water enters the sample liquid part of the pipette, and the sample liquid level of the pipette is flush with the liquid level of the measuring cylinder after the pipette is fixed in depth. Note that this portion of the sample liquid in the pipette is not taken at a constant depth h. The sample solution is not completely taken in the shadow part, but is partially supplemented at the upper part, so that the final result is small (in terms of the weight of the soil after the removed solution is dried).
