Novel distillation instrument

Abstract

A novel distillation instrument comprises a rack, a distillation bottle, a condensing pipe and a backflow bottle. A heating bath and a heating chamber are arranged on the rack. The condensing pipe penetrates through the heating bath. The backflow bottle is arranged in the heating chamber. A distillation opening of the condensing pipe is formed in the heating chamber. The position, outside the heating chamber, of the rack is provided with a cabinet door. The heating bath is a water bath or an oil bath. According to the distillation instrument with the novel structure, due to the fact that overall controllability of the instrument is improved, the test time of a single sample is reduced by 50%, working efficiency is improved by 100%, an operator can analyze one sample with an old instrument within 40 minutes but four samples with the novel instrument, liquefied gas is avoided, potential safety hazards are reduced, and energy consumption is reduced; in addition, the whole instrument is easy to operate, and staff can easily learn how to use the instrument.

Description

technical field [0001] The invention relates to a distillation device, in particular to a novel distillation apparatus. Background technique [0002] When analyzing the distillation range of anthracene oil, the anthracene oil has a high freezing point and high viscosity, and is easy to deposit in the condenser tube, and also deposits at the distillation outlet, causing the distillate to fail to distill normally, and the anthracene oil will produce yellow crystals in the measuring cylinder. resulting in inaccurate readings. In the traditional anthracene oil distillation process, liquefied gas torches are used to heat the condensing tube and measuring cylinder to solve these problems. However, liquefied gas torches are very unsafe and can easily cause fires, explosions and other accidents. [0003] Moreover, the heating operation of the liquefaction blowtorch is complicated, and one person has to keep heating the condenser tube, so that one person can only analyze one sampl...

Problems solved by technology

[0002] When analyzing the distillation range of anthracene oil, the anthracene oil has a high freezing point and high viscosity, and is easy to deposit in the condenser tube, and also deposits at the distillation outlet, causing the distillate to fail to distill normally, and the anthracene oil will produce yellow crystals in the measuring cylinder. cause inaccurate readings

In the traditional anthracene oil distillation process, liquefied gas torches are used to heat the condensing tube and measuring cylinder to solve these problems. However, liquefied gas torches are very unsafe and can easily cause fires, explosions and other accidents

[0003] Moreover, the heating operation of the liquefaction torch is complicated, and one person has to heat the condenser tube continuously, so that one person can only analyze one sample, and the efficiency is very low

[0004]On the other hand, manual heating is required for blowtorch heating, and the heating temperature cannot be precisely controlled, resulting in large errors in analysis data and poor repeatability
