A Method for Automatically Measuring the True Relative Density of Coke

Abstract

The invention relates to a method of automatically measuring true relative density of coke. A multistation modular experiment device automatically accomplishes a continuous measurement process of the true relative density of the coke and comprises an experiment host, a controller and a man-machine interactive system; the experiment host comprises a mechanical arm; glass bottles clamped by the mechanical arm can arrive at a plurality of experiment stations; an automatic measurement process comprises the following steps: step I, cleaning the glass bottle, step II, obtaining mass m<2> of the glass bottles full of water, step III, obtaining mass m<3> of the glass bottles full of a coke sample and the water, and step IV, calculating an experiment result. According to the method, an artificial experiment procedure is simulated; the intelligent mechanical arm is matched with the stations with different functions; the automation of the experiment process is achieved; the measurement process of the true relative density of the coke can be accomplished quickly and accurately; manpower waste and labor force intensity are greatly reduced; the accuracy of a measurement result is improved.

Description

technical field [0001] The invention relates to an experiment method, in particular to a method for automatically measuring the true relative density of coke. Background technique [0002] The relative density of coke is the ratio of the mass of dry coke sample with particle size less than 0.2mm to the same volume of water. The Chinese standard GB4511.4-2008 stipulates the method for the determination of the true relative density of coke. The principle is: put the sample in a density bottle, add air-free distilled water, heat the water to boil, remove the adsorbed gas, measure the mass of the same volume of water according to the Archimedes principle, and calculate the true relative density of the sample. The test procedure is to wash the density bottle with a mixture of potassium dichromate and sulfuric acid, rinse it fully with distilled water, fill it with air-free distilled water, tighten the stopper and immerse the bottle (to the bottle neck) in a place where the tempe...

Problems solved by technology

During the experiment, it is necessary to manually weigh the sample, load the sample, clean the density bottle, and also need to prepare air-free distilled water and prepare t°C distilled water. During the experiment, a lot of intermittent waiting time is required, so that it takes at least 10 minutes to complete the experiment. more than 3 hours

[0004] Since manual operation has an impact on the deviation of the measurement results in many of the above-mentioned links, and due to the heavy workload of the measurement, this repeated frequent operation requires a certain amount of manpower with skilled operation skills, which makes the industrial production auxiliary link not only There is a phenomenon of wasting manpower, and at the same time, the deviation of the experimental results directly affects the quality of the produced coke products; in order to solve the current backward measurement method, there is an urgent need for a new method that can be efficient, accurate, reduce manpower allocation, and reduce labor intensity. method to achieve target requirements
