[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0024] like Figures 1 to 5 As shown, a novel intelligent graphite digester furnace includes: a shell 100, a heating device, a control device, a waste gas absorption device, and a support 500; the shell 100 has a receiving cavity and a placement groove 110, the heating device is disposed in the placement groove 110, the control device is partially disposed in the receiving cavity, and the other part is located on the side of the shell 100; the support 500 is disposed on the shell 100 and is located above the placement groove 110, and the waste gas absorption device is disposed on the support 500.

[0025] Specifically, the heating device includes a heating base 210, a heating rod 220, and a graphite block 230. The heating base 210 is disposed within the placement groove 110, the heating rod 220 is connected to the heating base 210, and the graphite block 230 is disposed above the heating base 210. A composite heat insulation layer is provided on the inner wall of the placement groove 110, and the composite heat insulation layer is located outside the heating base 210 and the graphite block 230. The graphite block 230 has several placement slots 231, which are equidistantly spaced. The control device includes a control system and a touch screen 310. The control system is disposed within the accommodating cavity, and the touch screen 310 is rotatably disposed outside the housing 100, and the touch screen 310 is electrically connected to the control system.

[0026] In the above embodiment, the bottom of the accommodating cavity has an opening, and a heat dissipation plate 600 is detachably installed at the bottom of the accommodating cavity, the heat dissipation plate 600 covering the opening. There are four heating rods 220, and a temperature sensor is installed on the heating base 210. All four heating rods 220 and the temperature sensor are electrically connected to the control system. The support 500 is used to hold several digestive tubes 700, and each digestive tube 700 is movably inserted into a placement port 231.

[0027] In one embodiment, the waste gas absorption device includes a waste gas collector, a waste discharge pipe 420, and a waste gas processor 430. The waste gas collector is mounted on the support 500, and each digestion pipe 700 is detachably connected to the waste gas collector. The waste gas collector is connected to the waste gas processor 430 via the waste discharge pipe 420. The waste gas collector includes a connecting frame 411 and a plurality of waste gas collection pipes 412. The connecting frame 411 is mounted on the support 500, and each digestion pipe 700 is connected to one waste gas collection pipe 412. All of the plurality of waste gas collection pipes 412 are connected to the waste discharge pipe 420.

[0028] When conducting experiments using this intelligent graphite digestion furnace, the support 500 is positioned above the placement slot 110.
