Distillation device for detection chamber

Abstract

The invention discloses a distillation device for a detection chamber. The distillation device for the detection chamber comprises a steam generating bottle, a steam-water separator, a reaction pipe and a condensing pipe, wherein the upper end of the condensing pipe is provided with a condensed water outlet; the lower end of the condensing pipe is provided with a condensed water inlet; the condensed water inlet is externally connected with a water tank through a first pipeline; a water inlet flow rate meter and a water pumping pump are arranged on the first pipeline and at one end near the condensing water inlet; the water inlet flow meter is positioned between the water pumping pump and the condensing water inlet; a temperature sensor is arranged on the outer wall of the bottom end of thesteam generator; the distillation device also comprises a PLC (programmable logic controller); the water inlet flow rate meter, an electric furnace and the temperature sensor are respectively and electrically connected with the PLC. The temperature constancy of the heating device can be controlled; the flow rate of the condensing water can be effectively controlled; completion digestion of samples and total recovery of nitrogen are ensured; the accuracy of the experiment data and the credibility of experiment results are improved.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, in particular to a distillation device for a detection room. Background technique [0002] The Kjeldahl nitrogen analyzer is an instrument that calculates the protein content by measuring the nitrogen content in the sample based on the principle that the nitrogen content in the protein is constant. Because the method of measuring and calculating protein content is called the Kjeldahl method, it is called the Kjeldahl nitrogen analyzer, also known as nitrogen analyzer, protein analyzer, and crude protein analyzer. [0003] Chinese patent CN 206649003 U discloses "a kind of Kjeldahl nitrogen analyzer for detection", which includes a body, a steam pipe arranged at the front of the body, a condensation pipe, a boric acid dropping pipe and a sample digestion pipe arranged outside the steam pipe, There is a distiller and a condenser in the body, and the distiller is connected with the s...

AI Technical Summary

Problems solved by technology

[0004] However, the current Kjeldahl nitrogen analyzer still has some shortcomings: 1. It cannot effectively control the temperature of the heating device; 2. It cannot effectively control the flow rate of condensed water

Too high or too low temperature will make the sample incompletely digested, and the flow rate of condensate water is too fast or too slow will affect the recovery rate of nitrogen

These will lead to inaccurate test data and affect the analysis of test results
