Description

Graphite digestion instrument Technical Field The application relates to the technical field of graphite digestion instruments, in particular to a graphite digestion instrument. Background The graphite digestion instrument is an analysis instrument used in the fields of chemistry, agriculture, forestry, environmental science and technology and resource science and technology, and is commonly used for digestion of samples such as soil, food, fertilizer, rock and the like. The graphite digestion instrument generates heat through the graphite blocks to generate high temperature to digest the sample placed in the digestion tube at high temperature, a user can customize the required temperature, and the instrument can automatically and evenly heat the temperature to the appointed temperature through a program and then keep constant temperature to continuously heat the sample. When the existing graphite digestion instrument is used, the digestion tube is directly inserted into the corresponding jack and then heated by the graphite digestion instrument, however, when the graphite digestion instrument is used, as the digestion tube is only partially positioned in the jack and the other part is positioned outside the graphite digestion instrument, when the existing graphite digestion instrument is used for heating the digestion tube, uneven heating is easy to occur, and the decomposition of a sample is not facilitated. Therefore, the application provides a graphite digestion instrument. Disclosure of utility model The graphite digestion instrument is characterized in that a heating cavity is arranged on the digestion instrument, a bearing frame is slidably arranged in the heating cavity, a buckling door is arranged on the digestion instrument and used for sealing the heating cavity, a graphite heating area of the digestion instrument is arranged in the heating cavity, when the graphite digestion instrument is used, the bearing frame is firstly moved out, a worker conveniently places a digestion tube into a corresponding jack, then slides the bearing frame into the heating cavity, closes the buckling door, provides a temperature-stable heating environment for the digestion tube through the sealed heating cavity, and then integrally moves out after heating is finished, so that heat dissipation is facilitated or a new digestion tube is taken and replaced by an experimenter.
