In order to reduce the impact of these pores on the product, the graphite is processed by an impregnation process. The graphite impregnation process is to impregnate the graphite material to make it have better corrosion resistance, electrical conductivity and thermal conductivity, thereby improving its application range and performance.

[0003] In this regard, China's patent application number: CN202111423796.8, discloses a stable and reliable anti-oxidation impregnation device for graphite electrodes, including a lower shell and an upper shell, the lower shell and the upper shell are opposite to each other, a rotating mechanism is arranged between the lower shell and the upper shell, the rotating mechanism can drive the lower shell and the upper shell to be displaced with each other, the impregnation liquid is placed in the lower shell, a first electric telescopic rod is arranged in the lower shell, a horizontal support plate is installed at the movable end of the first electric telescopic rod, a containing device is arranged on the support plate, and the containing device can be used to place the graphite electrode, which is characterized in that: a pressurizing device is arranged in the upper shell, the pressurizing device can pressurize the impregnation liquid, a rotating device is arranged in the containing device, the rotating device can drive the graphite electrode to rotate, and the rotation of the graphite electrode can make the impregnation fully carry out and the impregnation liquid be recovered.

[0004] The device can drive the material immersed in the impregnation liquid to rotate by installing an electric roller and a first roller on the support plate and the pressure plate respectively, so as to ensure the impregnation effect. However, when the device is turned on, the upper shell needs to be rotated to one side of the lower shell so that the upper shell is suspended. When the device is in use, the impregnation liquid attached to the graphite electrode needs to be thrown out by rotation. Therefore, a part of the impregnation liquid will adhere to the surface of the pressure plate in the upper shell. When the upper shell is removed from the lower shell, the adhered impregnation liquid will drip downward, causing waste and polluting the workstation. At the same time, after the graphite electrode is adhered to the impregnation liquid, it is inconvenient to take it out of the storage tank, which will affect the material placement and make it difficult to improve the use efficiency of the device.

The top inclined frame 28 drives the fixed ring 29 to lift when it is active. The fixed ring 29 drives the pull rope 34 to lengthen upward, which can release the tension on the pull rope 34. The receiving plate 31 is elastically acted on by the coil spring 33. The receiving plate 31 is rotated around the rotating shaft 32 inside the inclined groove 12, so that the side wall of the receiving plate 31 is attached to the inner wall of the inclined groove 12, and the receiving plate 31 can maintain an inclined state. The receiving plate 31 is located at the lower side of the movable arm 211 and the bracket 218, and can receive the impregnation liquid dripping from the movable arm 211 and the bracket 218 at the lower side, so that the dripping impregnation liquid is collected in the receiving plate 31, which is convenient for the impregnation liquid to converge on the top surface of the movable ring plate 214 along the receiving plate 31 and the guide groove 11, ensuring the convenience of taking and placing materials, and preventing the impregnation liquid on the pressing plate 17 from dripping on the limbs, ensuring safety, and the impregnation liquid can be recycled to avoid the impregnation liquid from polluting the environment;

[0059] After the material is replaced, the third electric push rod 27 is controlled to reset, and the third electric push rod 27 drives the top inclined frame 28, the movable arm 211 and the bracket 218 to reset, and the top inclined frame 28 pulls the fixed ring 29, and the fixed ring 29 pulls the pull rope 34, so that the receiving plate 31 rotates around the rotating shaft 32, so that the receiving plate 31 can be kept in a vertical state. After the first electric push rod 13 is controlled to reset, the movable cover 14 descends, and the receiving plate 31 is stored in the receiving groove 15, and the side of the receiving plate 31 that receives the impregnation liquid can be exposed, so as to avoid contamination of the receiving groove 15, and at the same time, it can ensure that the impregnation liquid on the receiving plate 31 drips downward and gathers.
