Double-column blowing-needle-height-automatic-adjusting nitrogen blowing concentrator

Abstract

The invention discloses a double-column blowing-needle-height-automatic-adjusting nitrogen blowing concentrator and belongs to the field of a nitrogen blowing concentration or purification device. Thenitrogen blowing concentrator comprises a heat insulation shell base, a heating plate, a heating tank, a test tube stand, a nitrogen blowing device, a temperature sensor and an integrated control device. The heating plate is mounted in the heat insulation shell base; the heating tank is mounted on the heating plate; the test tube stand is mounted on the heating tank; the temperature sensor is mounted in the heating tank; the integrated control device is mounted on the front surface of the heat insulation shell base; and the nitrogen blowing device is mounted above the heat insulation shell base. The nitrogen blowing concentrator is characterized in that the nitrogen blowing concentrator also comprises a double-column lifting device and a water level alarm device. The nitrogen blowing concentrator can automatically adjust the height of the nitrogen blowing device, is stable in operation and high in positioning accuracy, can carry out nitrogen blowing concentration or purification on mixed liquid to be concentrated or purified in multiple tubes and can prevent dry burning of the heating tank.

Description

Technical field [0001] The invention relates to the field of nitrogen blowing concentration or purification devices, in particular to a double-column nitrogen blowing concentrator with automatic adjustment of blowing needle height. Background technique [0002] In the process of scientific research experiments, environmental monitoring and evaluation experiments, analysis and detection experiments, and material composition analysis and research, it is often necessary to use a nitrogen blowing concentrator to concentrate or purify the mixed liquid substances for subsequent in-depth research and analysis. The nitrogen blowing concentrator can heat, concentrate and purify the liquid samples to be tested and analyzed. The nitrogen blowing concentrator uses nitrogen to blow the surface of the liquid sample to be tested and analyzed to concentrate and purify the test sample to be tested for subsequent analysis and research. However, ordinary nitrogen blowing concentrators have the fol...

AI Technical Summary

Problems solved by technology

However, the ordinary nitrogen blowing concentrator has the following problems in the actual use process: 1. When the nitrogen blowing concentrator is in use, it is necessary to manually adjust the rise or fall of the nitrogen blowing device, which takes a long time to adjust and has a large position deviation; 2. There is no water level alarm device for the nitrogen blowing concentrator. When the nitrogen blowing concentrator is equipped with heating and evaporation, the water level will drop accordingly. The change of the water level in the heating tank inside the nitrogen blowing concentrator cannot be observed from the outside. Sometimes the heating tank may dry out and cause accidents. making it impossible to concentrate
