Cleaning device for flame cone in atomic absorption spectrometer

Abstract

A cleaning device used for a flame cone in an atomic absorption spectrum analyzer comprises a barrel body. The flame cone is fixed to the inner side wall of the barrel body. A first electric telescopic rod, a telescopic shaft and a motor are mounted on the inner wall of the bottom of the barrel body. The first electric telescopic shaft and the motor are located on the left side and the right sideof the telescopic shaft correspondingly. A cleaning agent is pumped into a barrel through a pumping device, meanwhile, an annular piston compresses springs to move downwards, and therefore the pressure intensity in the barrel is larger, and then when second through holes are aligned to third through holes at the next time, the cleaning agent in the barrel can be sprayed out from water spray holesfaster; when the cleaning agent is sprayed from the water spray holes, a certain distance is formed between the cleaning layer and the inner wall of the flame cone, and therefore the cleaning agent achieves stronger flushing and cleaning effects on the inner wall of the flame cone, meanwhile, rectangular plates swing up and down fast, and therefore the inner wall of the flame cone is beaten, and the function of reinforcing the cleaning effect is achieved; and time and labor are saved, and scheduled maintenance of the flame cone is facilitated.

Description

technical field [0001] The invention belongs to the field of cleaning devices for flame cones, in particular to a cleaning device for flame cones in atomic absorption spectrometers. Background technique [0002] The flame cone is a built-in part of the atomic absorption spectrometer, also known as the combustion head. The atomic absorption spectrometer is also called the atomic absorption spectrophotometer. The analyte in the sample passes through the flame cone under the flame, decomposes to produce atomic vapor, the ground state atoms of the element to be measured in the steam are absorbed, and the content of the element to be measured in the sample can be obtained from the degree of weakening of the intensity of the radiated light wave.

[0002] The flame cone is a built-in part of the atomic absorption spectrometer, also known as the combustion head. The atomic absorption spectrometer is also called the atomic absorption spectrophotometer. The analyte in the sample passes through the flame cone under the flame, decomposes to produce atomic vapor, and the ground state atoms of the element to be measured in the steam are absorbed, and the content of the element to be measured in the sample can be obtained from the degree of weakening of the intensity of the radiated light wave. If the atom is ionized Insufficient, so that the number of atoms in the ground state decreases, the absorbance decreases, and the measured data is inaccurate. The maintenance and maintenance of the flame cone is an important part of instrument maintenance and maintenance. The inner wall of the flame cone needs to be cleaned regularly to prevent it from working normally. At the same time, the inner wall of the flame cone has high requirements for cleaning conditions. Manual scrubbing is too time-consuming and labor-intensive, and other scrubbing methods are not thorough.
