Structure-improved infrared spectrometer convenient to use

Abstract

The invention belongs to the technical field of infrared spectrum equipment, and particularly relates to a structure-improved infrared spectrometer convenient to use. According to the invention, the tube body hole, the liquid outlet tube, the hose, the bunching belt, the sliding cylinder unit, the mounting plate unit and the movable plate unit are arranged on the instrument box body, so that the purpose of efficiently and conveniently performing liquid drainage operation on the liquid pool of the infrared spectrometer is achieved. The invention has the following advantages: firstly, the liquid outlet pipeline of the liquid pool is provided with the hose section, and the opening and closing operation of the liquid outlet pipeline can be conveniently realized through the downward flattening operation of the hose, so that the effectiveness of the liquid outlet operation is ensured; and secondly, the hose and the liquid outlet pipe are tightened through the bunching belt, the sealing performance of the foundation is guaranteed, the air cylinder can tighten the bunching belt again, the high sealing performance of the liquid outlet pipe is guaranteed, and liquid leakage is not prone to occurring.

Description

technical field [0001] The invention belongs to the technical field of infrared spectrometers, and in particular relates to a structure-improved infrared spectrometer which is convenient to use. Background technique [0002] Infrared spectrometer refers to an experimental device that can use infrared spectrum to analyze and identify material molecules. It irradiates a beam of infrared rays of different wavelengths on the material, and certain infrared rays of specific wavelengths are absorbed to form The specific infrared absorption spectrum can infer the molecular structure of the substance. [0003] Existing infrared spectrometers need to inject liquid samples into the liquid pool during use, and after the batch of liquid samples are tested, they need to perform a liquid discharge operation. The existing liquid discharge operation is simply Open the cover of the drain pipe, and there are at least the following problems in the drain part of this structural style: first, th...

Problems solved by technology

[0003] Existing infrared spectrometers need to inject liquid samples into the liquid pool during use, and after the batch of liquid samples are tested, they need to perform a liquid discharge operation. The existing liquid discharge operation is simply Open the cover of the drain pipe, and there are at least the following problems in the drain part of this structural style: first, the sealing of the entire drain pipe is not enough, and the cover is easy to leak; second, in order to facilitate the rotation and opening of the cover In order to operate together, the cover must be set outside the instrument, so the length of the drain line is relatively large. Every time a liquid sample is added to the liquid pool, the relatively long drain line must be filled first, so that The liquid sample in the liquid pool can only reach a sufficient amount, which will eventually cause a lot of waste of liquid samples

[0006] In the infrared spectrometer in this utility model patent, although the sealing degree of the discharge pipe is sufficient, the controllable opening and closing operation is convenient, and the overall discharge and liquid discharge operation is basically effective, but the "electric push rod 11, movable plate 12, fixed Plate 10", etc., are all located in the discharge pipe, that is, they are in direct contact with the liquid sample, so the entire structure of the control opening and closing is easily corroded, conductive and leaking, so its life is not long, and it also has extremely high requirements for the supporting circuit layout. This is very troublesome
