Automatic moisture tester

Abstract

The invention discloses an automatic moisture tester. The automatic moisture tester comprises a moisture test module for performing a moisture test to materials and a crucible for containing the materials; the moisture test module comprises a material transfer device for transferring the materials to the moisture test module; a manipulator device for completing conveying of the materials, transferred by the material transfer device, between all devices of the moisture test module; a weighing device for weighing the materials conveyed by the manipulator device; a drying box device for drying the materials weighed by the weighing device; the materials are transferred to the moisture test module through the material transfer device, and the manipulator device conveys the materials on the material transfer device to the weighing device for weighing, then conveys the materials to the drying box device for drying and then conveys the materials to the weighing device for weighing to complete a test. The automatic moisture tester has the advantages of high automation level, high equipment integration level, high working efficiency and high test accuracy.

Description

technical field [0001] The invention mainly relates to the field of material sample collection and analysis equipment, in particular to an automatic moisture tester. Background technique [0002] For the sampling and analysis of materials (such as ore and coal), each country has mandatory standards, and sampling and analysis must be carried out in accordance with the standards. The principle of the sample collection and analysis process is to gradually reduce the particle size and quality of the collected samples on the premise of not destroying the representativeness of the samples, until the particle size and mass (weight) accuracy requirements of the laboratory test are met. , and then carry out relevant test analysis on samples that meet the requirements. During this process, there can be no loss of samples, and no physical or chemical changes can occur in the samples, otherwise the final test results will be affected. [0003] Take coal material analysis as an example...

AI Technical Summary

Problems solved by technology

[0005] (1) The moisture testing equipment and the sample reduction equipment are set separately, and the degree of automation and integration of the moisture testing equipment itself is not high, so the moisture testing work needs to be completed back and forth between multiple instruments, the work efficiency is low, and it is easy to cause sample damage. Water loss, sample confusion, sample loss, etc., ultimately affect the accuracy of the analysis

[0006] (2) The moisture testing equipment adopts the blast heating method for heating and drying, the drying efficiency is low, the heating is uneven, and the experiment cycle is long, which affects the entire sample analysis process

[0007] (3) Materials need to be leveled manually

If the material is not flattened, the different thickness of the accumulation will cause the distortion of the moisture detection, which will affect the accuracy of the test analysis; and the manual leveling, one is labor-intensive and affects the work efficiency; the other is that the artificial leveling cannot guarantee the thickness distribution of the material average, there may still be the possibility of inaccurate analysis

[0008] (4) The crucible is not clean, and samples often remain inside and outside the crucible, which will mix with the next batch of samples and cause pollution, affecting the accuracy of the next batch of tests

[0009] (5) The equipment structure setting is unreasonable. Each crucible in the equipment needs to occupy a separate space. If there are many crucibles to be stored, the equipment must also be designed into a large volume simultaneously, resulting in a large space occupation
