[0001] The utility model relates to the technical field of air intake devices, in particular to an air intake device at the bottom of a graphite purification furnace. Background Art

[0002] During the production and processing of graphite materials, the acid and alkali resistance of graphite is utilized. Alkali and graphite are mixed evenly in a certain ratio, and the materials are calcined in a graphite purification furnace.

[0003] The graphite purification furnace is connected to the air intake device on one side during the material processing. The gas is filled into the interior of the graphite purification furnace through the air intake pipe of the air intake device, which can produce a chemical reaction with the material inside to realize the processing of the material.

[0004] During air intake, the gas enters through the outlet end of the air inlet pipe and makes the gas contact with the material inside the graphite purification furnace to produce a chemical reaction. However, since the diameter of the air inlet pipe is small and the outlet end of the air inlet pipe is directly connected to the bottom end of the graphite purification furnace and the position is fixed, it is not convenient to evenly disperse the gas to all parts of the material. The contact between the gas and the material is not sufficient, thereby reducing the speed of the contact reaction between the gas and the material and reducing the effect of the use of the air intake device. In view of the shortcomings of the existing technology, we propose a bottom air intake device for the graphite purification furnace to solve the above problems. Utility Model Content

[0038] A filter plate 203 is provided at the top of the air inlet pipe 101, and the filter plate 203 filters impurities in the gas. The air inlet pipe 101 is connected to the air inlet equipment on one side, so that the gas is filled into the interior of the purification furnace body 1 through the air inlet pipe 101. It should be noted that the filter plate 203 and the cleaning scraper 2031 are respectively connected to the drive shaft 2021 and the air inlet pipe 101. When the drive shaft 2021 rotates, the filter plate 203 and the cleaning scraper 2031 can be in a relative rotation state, and then the cleaning scraper 2031 can be rotated to clean the impurities at the bottom end of the filter plate 203.
