Abstract
The utility model relates to a detector of an automatic analyzer for measuring sulphur, which comprises a volumetric flask (7), an alkaline liquid burette (4), a sulfur dioxide air pipe (5) and a hydrogen peroxide burette (6), wherein a liquid outlet pipe (9) is arranged at the lower end of the volumetric flask (7); the alkaline liquid burette (4) is arranged in an accommodation bottle; one end of the sulfur dioxide air pipe (5) is arranged in the accommodation bottle, and the end is communicated with a sample combustion chamber; one end of the hydrogen peroxide burette (6) is arranged in the volumetric flask, and the end is communicated with a hydrogen peroxide volumetric flask. The utility model is characterized in that a pH value sensor is arranged in the volumetric flask (7). The utility model is used for measuring the sulfur content of coal, steel and other materials. Compared with the general visual measure method, the utility model has the advantages of accurate measurement, high speed of measurement, etc.
Description
The utility model relates to a kind of measurement mechanism of material sulfur content.
In the prior art,, analyze the sulphur in iron and steel and the coal material, must at first material sample be placed in 1200 ℃ the high temperature furnace, feed pure oxygen, carry out the oxygen-enriched combusting reaction according to international iso standard method and domestic GB standard method regulation.The sulphuric dioxide that is generated by reaction is absorbed in superoxol, and the reaction back generates sulfuric acid solution, and then carries out titration with standard solution of sodium hydroxide, makes it carry out neutralization reaction.Before the NaOH titration, in the volumetric flask that sulfuric acid solution is housed, splash into PH reagent, range estimation NaOH titration is to the terminal point of neutralization reaction, and the amount of splashing into of measuring NaOH this moment can calculate the sulfur content in the material.In this way and measurement mechanism mainly rely on operator's experience, can't detect automatically.
The purpose of this utility model is to provide a kind of pick-up unit of the survey sulfur automatic analysing instrument of can be automatically the sulfur content in the volumetric flask being measured.
The technical solution of the utility model is: it comprises that the lower end is provided with the volumetric flask of drainage pipe, places the alkali-titration pipe in the volumetric flask, an end that is connected with the sample combustion chamber to place the sulphuric dioxide tracheae in the volumetric flask, an end that is connected with the hydrogen peroxide volumetric flask to place the interior hydrogen peroxide buret of volumetric flask, is provided with the pH value sensor in the described volumetric flask.
The utility model compared with prior art has following advantage:
Since in the volumetric flask and terminal point adopt the PH electrode to carry out the sensing indication, in and the current potential generation hop of terminal point change, so current potential that can be by measuring the pH value sensor accurately in the mensuration and terminal point and then is measured automatically to the sample sulfur content.Its measurement result is more more accurate than ocular estimate, quick.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a structural front view of the present utility model; Wherein:
[1]. solenoid valve; [2] .PH value sensor; [3]. bottle stopper; [4]. the alkali-titration pipe; [5]. the sulphuric dioxide tracheae; [6]. the hydrogen peroxide buret; [7]. volumetric flask; [8]. solenoid valve; [9]. the drainage pipe.
Embodiment: referring to accompanying drawing, volumetric flask of the present utility model [7] lower end is provided with drainage pipe [9], and drainage pipe [9] is provided with solenoid valve [8], is used for after test finishes the fluid discharge in the volumetric flask [7].The bottle stopper of volumetric flask [3] is provided with alkali-titration pipe [4], and described alkali-titration pipe [4] is provided with solenoid valve [1], and this solenoid valve [1] is used for control titration sodium hydroxide solution in volumetric flask [7], so the end of alkali-titration pipe [4] is in volumetric flask.Sulphuric dioxide tracheae [5] is connected with the sample combustion chamber, and the one end places in the volumetric flask.Hydrogen peroxide buret [6] is connected with the hydrogen peroxide volumetric flask, and an end of described buret [6] places in the volumetric flask, is provided with pH value sensor [2] in the described volumetric flask [7].During test, the sample that scale is good is put into through in advance at the porcelain boat of 1250 ℃ of calcinations, and the boat that will fill sample with the nickel filament hook slowly pushes the high temperature constant temperature district of high-temp combustion tubular furnace again, and aerating oxygen keeps certain oxygen flow subsequently.Burn after 4 minutes, the gas that contains sulphuric dioxide that sample burning back produces enters volumetric flask [7] through sulphuric dioxide tracheae [5], owing to splashed into an amount of hydrogen peroxide by hydrogen peroxide buret [6] in the volumetric flask, so in volumetric flask [7], can produce the sulfuric acid of some.In volumetric flask [7], splash into sodium hydroxide solution by alkali-titration pipe [4] neutralization reaction can take place, in and during terminal point PH sensor [2] produce the potential change of hop, the amount of splashing into of calculating NaOH this moment can be learnt the sulfur content in the sample.
