technical field
The present invention relates to a digestion instrument with internal heating for wet digestion, belonging to the field of analytical instrument manufacturing.
Background technology
The commonly known digestion instruments are external heating digestion instruments or microwave digestion instruments. External heating digestion equipment consumes a large amount of electricity and heats up slowly; The pressure inside the digestion tank of the microwave digestion instrument is greater than 200Kg/cm2, and safety issues should be considered. It is necessary to design an internal heating digestion instrument with fast heating, low pressure, and low energy consumption.
Invention content: The present invention designs a digestion instrument with an internally heated quartz digestion tube for wet digestion.
The technical solution of the present invention is:
Install two straight channels at the bottom of the quartz internal heat digestion tube, with straight heating wires installed on the inner wall of the channels, and the outer wall of the channels immersed in the internal heat digestion tube to directly heat the digestive agent. There is a half hole at the bottom of the quartz internal heat digestion tube for installing sensors. The height limit seat is fixed in the middle of the internal heat digestion tube, and the temperature sensor is fixed at the bottom of the quartz internal heat digestion tube. The straight heating wire is fixed on the height limit seat and secured with stainless steel screws. Two temperature sensor wires and two straight heating wire heating wires are connected to the proportional temperature control meter on the left side of the chassis. When approaching the control temperature, the voltage of the heating wire decreases proportionally. The DC heating voltage of the heating wire varies between 0 * 24V. Use a 3-digit 2-piece switch to select between temperature controlled digestion mode and non temperature controlled digestion mode.
The beneficial effects of the present invention are:
Fast heating, low pressure, low energy consumption of 80W, safe. There was no overflow during the experiment of dissolving boiled milk.
