When the flexible rope 524 is straightened, the dipping tank 3 is continuously rotated, and the flexible rope 524 pulls the movable end of the second telescopic rod 522, so that the grinding plate 51 is contracted. As the impregnation tank 3 continues to rotate, the rotating ring 523 starts to rotate.
Referring to fig. 2, the heater 6 is fitted and fixedly mounted to the flow dividing plate 41.
Heating the impregnation fluid by the heater 6 reduces the viscosity of the impregnation fluid, making it easier to flow, which helps the impregnation fluid to be distributed more evenly over the surface and the internal pores of the material.
Referring to fig. 1, a vacuum pump 7 is fixedly installed on a mounting frame 22, and a suction end of the vacuum pump 7 is communicated with the inside of the dipping.
Under the vacuum condition, the impregnating solution can more easily permeate into the micro-pores of the material, thereby being beneficial to improving the impregnating quality.
The implementation principle of the impregnating device for graphite electrode production provided by the embodiment of the application is as follows:
Before use, the motor 421 is started, the motor 421 drives the first belt wheel 422 to rotate, the first belt wheel 422 drives the belt 424 to rotate, the belt 424 rotates to drive the second belt wheel 423 to rotate, and the second belt wheel 423 rotates to drive the dipping tank 3 to rotate. The flexible cord 524 is wound around the rotating ring 523. The dipping tank 3 continues to rotate, the flexible rope 524 is straightened and pulls the movable end of the second telescopic rod 522, the movable end of the second telescopic rod 522 moves away from the fixed end, hydraulic oil in the rod cavity of the first telescopic rod 521 is pumped into the rodless cavity of the second telescopic rod 522, so that the movable end of the first telescopic rod 521 moves towards the direction close to the fixed end, and the grinding plate 51 contracts accordingly. At the same time, the spring 525 is stretched. Then, the motor 421 is turned off, the mount 431 is removed, the graphite electrode to be impregnated is fixed by using the three-jaw chuck 433, the mount 431 is reinstalled, and then the movable end of the limit lever 435 is inserted into the clamping groove 434. At this time, the motor 421 is reversely started, the dipping tank 3 starts to reversely rotate, and the movable end of the second telescopic rod 522 is reset under the action of the elastic force of the spring 525, so that the grinding plate 51 extends out and is abutted against the side wall of the graphite electrode. The dipping tank 3 continues to rotate, the winding of the flexible rope 524 is first canceled and then wound around the dipping tank 3 in the opposite direction. When the flexible rope 524 is straightened, the dipping tank 3 is continuously rotated, and the flexible rope 524 pulls the movable end of the second telescopic rod 522, so that the grinding plate 51 is contracted. As the impregnation tank 3 continues to rotate, the rotating ring 523 starts to rotate. At the same time, the impregnating liquid slowly flows along the inner wall of the impregnating vessel 3 and the flow dividing plate 41, and flows from the gap between the flow dividing plate 41 and the side wall of the graphite electrode to the other end of the impregnating vessel 3. In the flowing process, the impregnating solution is contacted with the surface of the graphite electrode to impregnate the graphite electrode. Compared with a stirring mode, bubbles are less prone to be generated due to slow flow of the impregnating solution, and the impregnating quality is improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
