Background

In the industrial field, liquid ammonia can be used as a device product, and also can be used as a raw material of some chemical products, especially as a raw material, in-factory inspection and analysis are required, and inspection of the raw material requires inspection worker supervision sampling and inspection and analysis.

At this stage, the conventional assay analysis of liquid ammonia was performed by sampling using a Li Senke susceptor, and then slowly evaporating the sampled Li Senke susceptor at room temperature. The problems are: when the room temperature is low in winter, the evaporation speed is slow, so that the analysis efficiency is affected; liquid ammonia has high toxicity, is corrosive to skin, respiratory mucosa and eyes, and is unfavorable for physical and mental health of laboratory staff after long-time analysis.

The utility model aims to overcome the defects in the prior art and provides a liquid ammonia rapid evaporation analyzer.

In order to achieve the above object, the technical scheme of the present utility model is as follows: a liquid ammonia rapid evaporation analyzer is characterized in that: including water bath and circulating water pump, the water bath includes the pot body and temperature controller, the temperature controller sets up in the pot body lateral wall, circulating water pump passes through inlet tube and outlet pipe and pot body circulation intercommunication, the internal heating rod and the temperature sensor of being equipped with of pot, heating rod and temperature sensor respectively with temperature controller electric connection, the internal lateral wall of pot is equipped with one row of several evenly distributed's acceptor mount and one row of several evenly distributed's base, the base is located acceptor mount below, pot body top is equipped with the support and takes the single hole rubber buffer of pipe, be equipped with one row of several evenly distributed's through-hole on the support, the single hole rubber buffer of activity grafting in the through-hole, the export of single hole rubber buffer pipe inserts the fume hood.

Further; the front end of the bearing device fixing frame is provided with a U-shaped opening, the U-shaped opening is closed by a spring, and the front end of the base is provided with a jack.

The utility model has the beneficial effects that:

1) According to the utility model, the receiver fixing frame and the base are arranged in the pot body, the Li Senke receiver can be fixed, the Li Senke receiver is sealed by the single-hole rubber plug with the guide pipe, and evaporated gas ammonia can enter the fume hood for treatment and then is discharged into the atmosphere, so that an analysis sample is separated from an assay personnel in the analysis process, and the harm of liquid ammonia evaporation to a human body is avoided.

2) The water in the pot body is circulated through the circulating water pump, sudden boiling caused by uneven local heating is avoided, and the water temperature is uniform. The Li Senke bearing device is placed in the water bath, so that the phenomenon that the sample analysis efficiency is affected due to too low temperature and too slow evaporation in winter can be avoided, and the analysis error caused by uneven heating of the sample due to too high temperature and too fast evaporation in summer can also be avoided.
