Problems solved by technology

In the extraction process of the traditional infrared oil measuring instrument, all the samples are transferred to the separatory funnel, which requires manual shaking
Not only is the extraction incomplete and labor-intensive, but it also brings errors due to the different degrees of shaking each time

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The structure of the infrared automatic oil measuring and extracting device of the present invention is as follows: figure 1 As shown, it includes a spherical tank body 1, the upper end of the tank body is provided with a liquid inlet pipe, the liquid inlet pipe is provided with a carbon tetrachloride liquid inlet port 2 and a water sample liquid inlet port 3, and a stirring magnet 4 is provided in the center of the tank body. , The bottom of the tank body is provided with a discharge pipe 5, and the upper side of the tank body is provided with an overflow pipe 6. The liquid inlet pipe is located at 0° above the tank body, and the liquid discharge pipe is located directly below the tank body.

[0025] Wherein, since the density of carbon tetrachloride is greater than that of water, the height of the carbon tetrachloride liquid inlet is ...

Abstract

The invention relates to an efficient extraction device and extraction method for infrared full-automatic oil content analysis. The extraction device is specifically composed of a stirring motor, a stirring magneton, a cell body, a carbon tetrachloride liquid inlet pipe, a water sample inlet pipe, an upper overflow pipe, and a lower liquid discharge pipe; according to a clockwise stirring direction, the carbon tetrachloride liquid inlet pipe and the water sample inlet pipe are located at the upper part of a cell body, a lower liquid discharge pipe is located below the cell body, and the upperoverflow pipe is located at a left upper part. The whole cell and pipeline are made of polytetrafluoroethylene material, thereby avoiding the non-specific adsorption on a target object. The device disclosed by the invention is applied to a full-automatic infrared oil content analyzer, the space occupied by an extraction container is reduced, and the extraction efficiency is improved more obviously.

Description

technical field [0001] The invention relates to a fully automatic oil measuring high-efficiency extraction device and an extraction method, which are used for stirring, mixing, extracting and separating water samples and extracts by a fully automatic infrared oil measuring instrument, and belong to the technical field of analytical chemical sample pretreatment. Background technique [0002] Pretreatment is an important step in the analysis of complex samples. An effective pretreatment method can ensure the accuracy of the measurement results, improve the sensitivity of the method, eliminate interference in the measurement, and maintain the stability and reliability of the instrument. In the infrared oil measuring instrument, stirring and extraction are the main pretreatment processes. [0003] Stirring, through the rotation of the agitator, the mechanical energy is transferred to the fluid, and a high-turbulence full mixing zone is formed near the agitator, and a high-speed ...
