[0028] See also Figure 1-7 As shown, according to the above embodiment, a method for recycling waste battery raw materials is also provided, comprising the following steps: Step 1: recycling of used batteries. Used batteries are sent to a recycling box 1, crushed by a crushing roller 103, and the crushed used battery particles are filtered through a screen 301 of a filter screen 105. The filtered particles are sent to a dissolution box 2 through a feed pipe 107, and fully dissolved with a dissolving liquid under the stirring of a stirring rod 201. After dissolution, the used batteries are extracted and distilled by an extraction box 202 and a distillation box 203 to extract the raw materials in the used batteries. Step 2: Fire occurs during the crushing process. During the crushing process of the used batteries, the temperature sensor 108 monitors the temperature in the box in real time. When the temperature is greater than the preset range, the fire extinguishing mechanism 4 operates, and the driving motor 601 of the deployment component 6 works. The large sprocket 6011 and the first transmission chain 602 control the two small sprockets 6031 to rotate, so that the rotating shaft 603 drives the driving gear 6032 to rotate.

[0029] The working principle of the present invention is: During the process of crushing the waste batteries, the temperature sensor 108 monitors in real time whether the temperature during the crushing process meets the set range. When the monitored value is greater than the preset range, it is determined that the waste batteries are on fire. The controller automatically starts the unfolding component 6 and the flameproof component 7 in the fire extinguishing mechanism 4 in sequence according to the program, and the driving motor 601 works. The output end of the driving motor 601 drives the large sprocket 6011 to rotate, and controls the small sprockets 6031 on both sides to rotate through the first transmission chain 602. The two small sprockets 6031 respectively drive the rotating shaft 603 to rotate, so that the two rotating shafts 603 drive the driving gears 6032 to rotate, and the two driving gears 6032 control the moving plate 605 to move through the meshing inner teeth 6051.

While the two rotating shafts 603 rotate, the installed transmission wheel 607 is also driven to rotate. The transmission wheel 607 drives another transmission wheel 607 to rotate through the second transmission chain 6071, so that the shaft 606 rotates along with the rotating shaft 603. The rotating shaft 606 drives the worm 608 to rotate. The two worms 608 both drive the meshing worm wheels 609 to rotate. The two worm wheels 609 both control the rotation of the threaded screw 610, so that the two blocking plates 611 move laterally along with the rotation of the screw 610 under the restriction of the box wall until the ends of the two blocking plates 611 abut against each other, thereby achieving the blocking of the bottom of the screen 301. Then, after the nozzle 6041 is exposed, the controller starts the vacuum pump 702, and the vacuum pump 702 delivers the carbon dioxide in the carbon dioxide storage box 701 into the air duct through the gas supply main pipe 703, the gas supply branch pipe 704 and the telescopic pipe 705, and sprays it out from the nozzle 6041 to extinguish the fire.
