Universal speed-adjustable multi-aperture digestive tract shaking device

Abstract

The invention belongs to the technical field of chemical analysis and detection and discloses a universal speed-adjustable multi-aperture digestive tract shaking device. The universal speed-adjustablemulti-aperture digestive tract shaking device comprises a spherical support body, a universal wheel, a base, a colloid digestive tract fixing device and a universal wheel motor, wherein the sphericalsupport body is fixedly connected to the upper part of the base, the colloid digestive tract fixing device is arranged at the inner part of the spherical support body, a colloid digestive tract ductsupport body is mounted at the inner part of the colloid digestive tract fixing device, and digestive tract jacks are evenly arranged on the colloid digestive tract duct support body. The universal speed-adjustable multi-aperture digestive tract shaking device is simple in structure, low in cost and long in service life, can shake up in batches, has a good shaking effect, greatly improves the shaking efficiency, can shake from multiple directions, the shaking time and the shaking speed are controllable, the phenomena that the variable coefficient of detection data is large because of the humanfactor like insufficient shaking times and even the data deviation occurs are avoided, and the success rate of detection of a sample by an instrument is increased.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, in particular to a universally adjustable multi-diameter digestive tube shaking device. Background technique [0002] The total nitrogen in tobacco is closely related to the taste, strength and irritation of tobacco after burning. Its content is an important indicator for evaluating the quality of tobacco and tobacco products. The continuous flow analysis method can quickly detect the total nitrogen content in tobacco, with a high degree of automation. It has been widely used in the tobacco industry. The analysis process for the determination of total nitrogen can be divided into two stages. The first stage is sample pretreatment, which is to digest and convert the analyte into ammonium to obtain the sample to be tested; the second stage is instrumental analysis. Samples and reagents to be tested are quantitatively sucked into a specific analysis module for mixed reaction...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a universal speed-adjustable method to solve the problems of low manual shaking efficiency caused by small shaking gaps in the digestive tube and poor uniformity caused by insufficient shaking times when the total nitrogen sample is measured by the continuous flow method. Multi-aperture digestion tube shaking device, shake in batches, greatly improve the efficiency of shaking, and shake in multiple directions, the shaking time and speed can be controlled, avoiding the variation of detection data caused by human factors such as insufficient shaking times The coefficient is large and even data deviation occurs, which improves the success rate of the instrument to detect samples
