[0031] In order to promote the reaction of the material in the inner container 1, it is usually necessary to heat the inner container 1, which is usually made of high-temperature-resistant alloy material or refractory material, and has a cylindrical shape, can withstand high temperature and material abrasion and corrosion. The inner container 1 is further provided with an outer shell 4, and the outer shell 4 and the inner container 1 are sequentially provided with a heat preservation layer 3, a refractory brick 16 and a heating layer 2.

[0032] In some embodiments, referring to Figures 1-3 As shown, the inner container 1 includes a feeding pipe 101, a feeding cone pipe 102, a straight pipe 103, a discharging cone pipe 104 and a discharging pipe 105 connected in sequence. The inner walls of the feeding cone pipe 102, the straight pipe 103 and the discharging cone pipe 104 are uniformly provided with baffles in the form of a ring. When the inner container rotates, the baffles can move with the material to the upper part and then fall down, which is beneficial to the full reaction between the materials.
[0033] Preferably, the straight pipe 103 is uniformly provided with first baffles 106 arranged in the axial direction of the straight pipe 103, and the feeding cone pipe 102 and the discharging cone pipe 104 are uniformly provided with second baffles 107 arranged in the form of a spiral.

The second baffles 107 form a spiral conveying effect, which is beneficial to guiding the material in the feeding cone pipe 102 to the straight pipe 103 to participate in the reaction, and prevents the material from entering the feeding pipe 101 from the feeding cone pipe 102 in the opposite direction, and is beneficial to guiding the silicon-carbon composite material reacted in the discharging cone pipe 104 out of the inner container 1, and facilitates unloading.
[0034] Preferably, the two ends of the first baffles 106 are respectively connected to one end of the second baffles 107 at the corresponding positions in the feeding cone pipe 102 and the discharging cone pipe 104.
[0035] In some embodiments, referring to Figure 1As shown, the outlet end of the inner container 1 is sleeved with a driven wheel 14, and the output shaft of the speed reducer motor 12 is sleeved with a driving wheel, and the driving wheel and the driven wheel 14 are all engaged with the transmission wheel 13, so that the speed reducer motor 12 drives the inner container 1 to rotate. The driven wheel 14 and the bearing seat 7 are all arranged outside the shell 4, so as to avoid being affected by high temperature.
[0036] In some embodiments, referring to Figure 1 As shown, the base 9 is provided with a hinge seat 11 on both sides, and the support 8 is provided with a hinge shaft hinged with the hinge seat 11. One end of the hinge shaft is fixedly connected to the support 8, and the other end is rotatably connected to the hinge seat 11. The telescopic rod of the oil cylinder 10 can be telescopically extended and retracted to rotate the support 8 in the hinge seat 11, so as to realize the state of tilting or laying flat.

The three ports of the three-way pipe 6 are all sealingly connected to the corresponding components. The carbon source material is first placed in the straight pipe 103. Although the feeding pipe 101 is affected by heat transfer, it also has a relatively high temperature, which is lower than that of other parts of the inner container 1. Liquid silicon material is added through the side port of the three-way pipe 6, which will become a gas in the feeding pipe and enter the reaction zone in the straight pipe 103. Therefore, the silicon source material of the device can use liquid silicon. The tail port of the three-way pipe 6 adds inert gas, which can prevent the reverse movement of the gas silicon in the feeding pipe 101, push the gas silicon into the straight pipe 103, and form an inert gas atmosphere in the inner container to prevent the material from being oxidized. The exhaust treatment device is connected to the tail end of the discharge pipe 105 to treat the mixed gas discharged from the discharge pipe 105. The mixed gas can be continuously discharged from the discharge pipe 105 to avoid the increase of the pressure in the inner container 1.
[0038] In some embodiments, referring to Figure 1 As shown, the shell 4 is further fixedly provided with a fan 15, and the air outlet pipe of the fan 15 extends into the inner container 1 to accelerate the dispersion of the gas silicon and the inert gas in the inner container 1.
