Full-automatic oil fume tester

Abstract

The invention provides a full-automatic oil fume tester which comprises a machine body platform, an ultrasonic extractor, a constant-volume sample disc, a XYZ three-dimensional mechanical arm. Reagentbottles are distributed on the machine body platform and used for containing extraction reagents; a sleeve provided with a sampling filter cartridge is distributed in the ultrasonic extractor, and asampling hole is formed in the top of the sleeve; the constant-volume sample disc is used for placing a colorimetric tube and is matched with a visual constant-volume system to achieve the purpose that a set amount of reagent is filled into the colorimetric tube; a main frame is fixed to one side of the machine body platform, a multi-way injection pump is installed on the main frame, and the multi-way injection pump is connected with a steel needle through a hose to achieve extraction and injection actions. And the steel needle is driven by the XYZ three-dimensional mechanical arm to move among the containers, so that the actions of extraction and injection are completed. According to the full-automatic oil fume tester provided by the invention, an experimenter only needs to put a sample into the full-automatic oil fume tester, and the full-automatic oil fume tester can complete all processes in a full-automatic manner; and the working efficiency of experimenters is improved, and the contact of the experimenters with toxic and harmful reagents is reduced.

Description

technical field [0001] The invention relates to a test measuring instrument, in particular to an automatic oil fume measuring instrument. Background technique [0002] Oil fume is a product formed by cooking oil and food under heating conditions. In terms of form, this oil fume contains particulate pollutants and gaseous pollutants like the flue gas produced by burning fuel in industrial furnaces, but the concentration of particulate matter in oil fume is much higher than that of volatilization. The particle concentration is about 8 to 25 times, and it is mainly inhalable particles (IP for short) with a particle size of <10 μm, which account for 60.04% to 80% of the total particle concentration. The concentration of soot particles and their particle size distribution are related to the cooking temperature. The higher the cooking temperature, the higher the particle concentration in the produced soot. In the catering industry, a large amount of cooking fume is discharged ...

Problems solved by technology

The test process of this method is a manual extraction method, which requires testers to inject the extraction reagent tetrachlorethylene (toxic reagent) into the filter cartridge, use ultrasonic extraction, and carry out tedious processes such as the transfer of the extraction reagent to constant volume and optical path measurement.

Using this test method, the work efficiency of the experimenters is low, and the experimenters are directly exposed to toxic and harmful reagents, which will also affect their health.
