Description
Technical Field
The invention belongs to the technical field of oil acid value detection, and relates to a container for automatically detecting a synthetic oil acid value.
Background
Oil acid number detects mainly including instrument automated inspection and manual titration detection, and in the manual titration detection, the erlenmeyer flask is used commonly and is carried out operations such as the oscillation, the stirring of sample, solvent and indicator, and the erlenmeyer flask is consequently great in the bottom surface, helps the interior liquid of bottle contact the water bath more fully, promotes the volatilization and the backward flow efficiency of titration process solvent. For the automatic titration assay, a cylindrical flask with a flat bottom and a single side is commonly used, and the structure of the flask is shown in detail in FIG. 1. The flask is generally about 50mm in diameter and about 100mm in height. When the flask is used for detecting the acid value of an oil product, the following defects are often caused: 1) the bottom is a unilateral plane and a unilateral arc surface, so that the device has a dispersing effect on a detection light source during automatic detection and has adverse effect on a detection result;
2) because the single-side plane is positioned at the bottom, the stirrer is also positioned at the bottom in the detection process, and the optical detection area is limited; 3) because the bottom unilateral is the plane, when stirring, stirring son work area is very limited, leads to the stirring process not enough, influences the color judgement of titration process acid-base reaction.
Disclosure of Invention
In order to overcome the problems in the prior art, the invention provides a container for automatically detecting the synthetic oleic acid value, which can reduce the divergence phenomenon of a light source in the detection process, increase the stability of a detection area and realize the full stirring of a solvent in the titration process.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a container for automatically detecting the synthetic oleic acid value comprises an upper detection area, a middle transition area and a lower stirring area which are sequentially connected from top to bottom; the upper detection area is of a rectangular structure, the middle transition area is of a rectangular-to-cylindrical frustum structure, and the lower stirring area is of a cylindrical structure; the upper detection area is provided with a container opening, and the bottom of the lower stirring area is parallel and level and is sealed.
The central axis of the upper detection area, the central axis of the middle transition area and the central axis of the lower stirring area are coaxial.
The height b of the inclined platform in the middle transition area is 5-25 mm.
The diameter D of the lower stirring area is equal to the length of the upper detection area and is 10-50 mm.
The height a of the upper detection area is 10-50 mm, and the width L is 6-40 mm;
the height c of the lower stirring zone is 5 to 30 mm.
The automatic detection container for the synthetic oleic acid value is made of quartz or borosilicate transparent glass material.
The invention has the advantages that:
the traditional acid value titration container is changed into a three-section type, namely an upper detection area, a middle transition area and a lower stirring area, wherein the upper detection area is made into a rectangular shape, and the lower stirring area is made into a cylindrical shape and is connected and transited through the middle transition area of an inclined table. By adopting the design, the invention can ensure that the bottom stirring area has enough effective stirring area in the automatic acid value detection process, so that the sample can be fully mixed, and the stirrer is separated from the monitoring area, thereby avoiding the influence of the monitoring area on the shielding of the detection area and the like; the middle transition area is connected with the upper detection area by using an inclined platform, so that the liquid in the middle and the liquid in the upper part can be fully mixed; the rectangle structure of upper portion detection zone is favorable to detecting the penetrability of light source, eliminates the testing result error that causes because of the cambered surface produces the scattering of light source, improves acid value automated inspection's precision and accuracy.
