During operation, the crusher 2 is placed at the crushing bed 6, and after the slag is poured into the crushing bed 6, the driving shaft crusher 2 is rotated by the driving system 4, and at the same time, the frame 1 is moved by the moving system 3, that is, the crusher 2 is driven to move in the crushing bed 6, so that the crusher 2 performs thermal crushing on the slag in the crushing bed 6, and at the same time, water is applied to the crusher 2 and the slag through the cooling mechanism 5, so that the crusher 2 and the slag are cooled, thereby extending the service life of the equipment; The cooling mechanism 5 includes a water tank 501, one side of the water tank 501 is connected to a water inlet pipe 502, the water inlet pipe 502 is connected to a water source, and water is transported from the water inlet pipe 502 to the water tank 501 through the water source, and a water outlet pipe 503 is fixedly penetrated on the other side of the water tank 501, and a nozzle 504 is installed at the outer end of the water outlet pipe 503, and the inner end of the air outlet pipe 509 is connected to a driving source, and the water in the water tank 501 is transported from the water outlet pipe 503 to the nozzle 504 and discharged through the driving source. During the thermal breaking, the water discharged from the nozzle 504 acts on the crusher 2 and the slag; The driving source includes a water pump 505 and a transmission pipe 506. The transmission pipe 506 is installed on the water pump 505. The drainage end of the transmission pipe 506 is connected to the inner end of the water outlet pipe 503. When the water pump 505 is started, the water in the water tank 501 is transported from the transmission pipe 506 to the water outlet pipe 503. There are multiple water outlet pipes 503, which are distributed along the length direction of the crusher 2. A nozzle 504 is installed at the outer end of each water outlet pipe 503, so as to increase the amount of water acting on the crusher 2 and the slag and improve the cooling effect; The driving source further includes a connecting pipe 507, both ends of which are sealed, the middle end of the connecting pipe 507 is connected to the water outlet end of the transmission pipe 506, and the inner end of the water outlet pipe 503 is connected to the connecting pipe 507. After the water in the water tank 501 is transported from the transmission pipe 506 to the connecting pipe 507, the water in the connecting pipe 507 is then transported to each water outlet pipe 503; The water tank 501 is provided with an air pump 508, and an air outlet pipe 509 is installed on the air pump 508. An auxiliary pipe 510 is provided on the water tank 501, and one end of the auxiliary pipe 510 is sealed and fixedly arranged on a side of the water tank 501 close to the nozzle 504, and the nozzle 504 is located in the auxiliary pipe 510. The air outlet end of the air outlet pipe 509 is connected to the auxiliary pipe 510, and the connection between the air outlet pipe 509 and the auxiliary pipe 510 is located on a side of the nozzle 504 close to the water tank 501; There are multiple auxiliary pipes 510, and the multiple auxiliary pipes 510 correspond to the multiple nozzles 504 one by one; During the water spraying of the nozzle 504, the air pump 508 is started to transport air to the air outlet pipe 509, and the air in the air outlet pipe 509 is then transported to the auxiliary pipe 510. The air in the auxiliary pipe 510 is discharged from the end of the auxiliary pipe 510 away from the water tank 501. Under the action of the airflow, the water spraying distance and force of the nozzle 504 can be increased, which makes it easier for water to penetrate into the steel slag, thereby improving the cooling effect of the steel slag. Here, it should be noted that the angle of the auxiliary pipe 510 and the angle of the nozzle 504 can be set according to the position of the slag and the crusher 2; An air inlet pipe 511 is fixedly provided at the bottom of the water tank 501, and an inlet end of the air outlet pipe 509 is fixedly passed through the top of the water tank 501. By controlling the water inlet amount of the water inlet pipe 502 and the water spraying amount of the nozzle 504, the air inlet end of the air outlet pipe 509 is always located above the water level in the water tank 501, and the air inlet end of the air inlet pipe 511 is immersed in the water in the water tank 501. When the air pump 508 is started, the air in the water tank 501 is transported to the air outlet pipe 509, and the air outside the water tank 501 is transported from the air inlet pipe 511 to the water in the water tank 501 and forms bubbles. The bubbles float up and then burst. When water acts on the slag and the crusher 2, water vapor is generated. The water vapor and dust generated by the slag itself enter the water in the water tank 501 along with the air flow. The water vapor is cooled by water to avoid scalding caused by the water vapor. The dust is also dissolved in the water, so that the water vapor is cooled and the dust is collected at the same time. The air inlet pipe 511 is located between the transmission pipe 506 and the water inlet pipe 502. A filter screen 512 is provided between the air inlet pipe 511 and the transmission pipe 506. The filter screen 512 intercepts impurities in the water to prevent the nozzle 504 from being blocked by impurities. The air inlet pipe 511 includes a first pipe section 5111, a second pipe section 5112 and a third pipe section 5113. The first pipe section 5111 and the third pipe section 5113 are both arranged vertically. The first pipe section 5111 is vertically fixed and passes through the bottom of the water tank 501. The second pipe section 5112 and the third pipe section 5113 are both located in the water tank 501. The top of the first pipe section 5111 and the top of the third pipe section 5113 are connected through the second pipe section 5112. In fact, the second pipe section 5112 is always located above the water level in the water tank 501 to prevent the water in the water tank 501 from being discharged from the water inlet pipe 502. The bottom end of the third pipe section 5113 is located in the water in the water tank 501. The second pipe is a hose, and the third pipe section 5113 is connected to a moving module, and the third pipe section 5113 is driven to move horizontally back and forth by the moving module. When the third pipe section 5113 moves back and forth, the water in the water tank 501 is stirred, which not only makes it easier for the water to absorb heat in the air and improve the cooling effect, but also makes it easier for dust to dissolve in the water; The moving module includes a lead screw 513 and a slider 514, the lead screw 513 is arranged horizontally, the slider 514 is threadedly connected to the lead screw 513, the lead screw 513 is driven by a motor 515, a guide rod 516 is movably penetrated on the slider 514, the guide rod 516 is fixedly arranged on the water tank 501, the guide rod 516 is parallel to the lead screw 513, the slider 514 is fixedly connected to the third pipe section 5113, the lead screw 513 is driven to reciprocate by the motor 515, so that the slider 514 reciprocates on the guide rod 516, and the reciprocating movement of the slider 514 drives the third pipe section 5113 to reciprocate synchronously; The third pipe section 5113 is connected with a stirring member, and the stirring member stirs the water in the water tank 501 through the reciprocating movement of the third pipe end, thereby improving the stirring effect of the water in the water tank 501, thereby improving the air cooling and dust dissolving effect in the water; The stirring member includes a vertically arranged rotating shaft 517, and the rotating shaft 517 is rotatably connected to the second pipe section 5112 through a bearing 518. A plurality of stirring rods 519 are fixedly arranged on the rotating shaft 517, and the plurality of stirring rods 519 are evenly distributed circumferentially around the rotating shaft 517. The stirring rods 519 are fixedly connected to the rotating shaft 517, and a gear 520 is installed at the bottom end of the rotating shaft 517. A rack 521 is fixedly arranged on the inner wall of the water tank 501, and the rack 521 is parallel to the lead screw 513. The rack 521 is meshed with the gear 520. During the reciprocating movement of the third pipe section 5113, the gear 520 is synchronously reciprocated on the rack 521, and the gear 520 drives the rotating shaft 517 to reciprocate. The reciprocating rotation of the rotating shaft 517 drives the stirring rods 519 to rotate synchronously, thereby improving the stirring effect of the water in the water tank 501. In summary, by allowing the water discharged from the nozzle 504 to act on the steel slag and the crusher 2, the crusher 2 and the steel slag can be cooled, thereby extending the service life of the equipment. Moreover, the air discharged through the auxiliary pipe 510 can increase the water spraying distance and strength of the nozzle 504, making it easier for water to penetrate into the steel slag, thereby improving the cooling effect of the steel slag. Secondly, by transporting water vapor and dust to the water in the water tank 501, the cooling of water vapor in the air and the collection of dust can be achieved, and the dust can be dissolved in the water, thereby achieving air purification while preventing water vapor from hurting people. In addition, by stirring the water in the water tank 501, the cooling effect of water vapor in the air can be improved while the dust can be easily dissolved in the water.
