In order to put the steel smelting solid waste into the inside of the broken recycling box 1 through the guide plate 21, and the steel smelting solid waste also needs to be guided to the broken gap between the fixed knife 18 and the broken knife roller 2 for broken treatment, and the broken treatment is ensured to be guided according to the specified position.

[0045] In this embodiment, as shown in the figure, Figure 1 -Figure 9 As shown, the other end of the crushing knife roller 2 is provided with a torque force sensor 22, the lower surface of the torque force sensor 22 is fixedly connected with a supporting block 23, and the supporting block 23 is fixedly connected with the crushing recovery box 1, the outside of the crushing recovery box 1 is provided with a controller 24, and the controller 24 is electrically connected with the electric cylinder 11, so as to start the crushing motor 25 through the controller 24, the reinforcing plate 26 supports the crushing motor 25, the crushing motor 25 provides a driving crushing force for the crushing knife roller 2, and the crushing knife roller 2 rotates on the sensing end of the torque force sensor 22, when the sensed torque force value of the crushing knife roller 2 exceeds the set protection torque force value of the controller 24, the stuck larger foreign matter is immediately processed, the electric cylinder 11 is started through the controller 24, and the processing speed is faster.

[0046] One end of the cavity groove shaft 6 is provided with a crushing motor 25 for driving the cavity groove shaft 6 to rotate, the lower surface of the outer wall of the crushing motor 25 is fixedly provided with a reinforcing plate 26, the reinforcing plate 26 is fixedly connected with the crushing recovery box 1, one side of the crushing motor 25 is provided with an outer cover 27, the outer cover 27 is fixedly connected with the crushing recovery box 1, and the crushing motor 25 is electrically connected with the controller 24, and the reinforcing plate 26 is used for supporting the crushing motor 25, so as to provide protection operation for the outside of the crushing motor 25 through the outer cover 27, to ensure that the output end of the crushing motor 25 stably drives the cavity groove shaft 6, and the outer wall of the crushing motor 25 can also be stably supported through the reinforcing plate 26.

[0047] The use principle of the steel smelting solid waste comprehensive recycling system is as follows:

[0048] Firstly, when the crushing recycling is carried out, the controller 24 starts the crushing motor 25, the reinforcing plate 26 is supported by the crushing recovery box 1, the reinforcing plate 26 supports the crushing motor 25, the crushing motor 25 is used for stably driving the cavity groove shaft 6 to rotate, the cavity groove shaft 6 drives the protruding block 5 and the transmission shaft 4 to rotate, and the protruding block 5 is limited to rotate in the cavity groove shaft 6. At the same time, the transmission shaft 4 drives the disengaging ring 7 to rotate, the disengaging ring 7 drives the two limiting rings 8 to rotate, the two limiting rings 8 rotate on the two sides of the rotating shaft ring 9, and the disengaging ring 7 stably rotates in the rotating shaft ring 9, the transmission shaft 4 and the protruding block 5 drive the rotating groove shaft 3 to rotate, the protruding block 5 is limited to rotate in the rotating groove shaft 3, and the rotating groove shaft 3 stably drives the crushing knife roller 2 to rotate in the crushing recovery box 1. The steel smelting solid waste is put into the crushing recovery box 1, and is put into the crushing recovery box 1 through the guide plate 19 and the material guide plate 21, and is guided into the crushing gap between the fixed knife 18 and the crushing knife roller 2, and the steel smelting solid waste is crushed and discharged between the crushing knife roller 2 and the fixed knife 18 through extrusion, and then the steel smelting solid waste can be comprehensively recycled.

[0049] Secondly, when the larger foreign matter in the gap between the crushing knife roller 2 and the fixed knife 18 is difficult to crush, the larger foreign matter will jam the gap between the crushing knife roller 2 and the fixed knife 18, so that the crushing knife roller 2 rotates on the sensing end of the torque force sensor 22, thereby supporting the support block 23 of the crushing recovery box 1, the support block 23 supports the torque force sensor 22, and the torque force sensor 22 can know the torque force value of the rotation of the crushing knife roller 2. When the torque force value sensed by the crushing knife roller 2 exceeds the protection torque force value set by the controller 24, it is known that there is a problem of being jammed by larger foreign matter, and the electric cylinder 11 is immediately started by the controller 24, the electric cylinder 11 pushes the linkage strip 10 to move right, the linkage strip 10 drives the rotating shaft ring 9 to move right, the rotating shaft ring 9 drives one of the limiting rings 8 to move right, the limiting ring 8 drives the disengagement ring 7 to move right, the disengagement ring 7 drives the protrusion 5 to move right, and the disengagement ring 7 simultaneously drives the transmission shaft 4 to move right. The transmission shaft 4 and the protrusion 5 start to disengage from the groove in the rotating groove shaft 3, and at the same time, the transmission shaft 4 and the protrusion 5 enter the long enough gap in the cavity groove shaft 6. Thus, the transmission shaft 4 and the protrusion 5 no longer provide rotary torque power to the rotating groove shaft 3, and the rotating groove shaft 3 no longer provides rotary torque power to the crushing knife roller 2, thereby avoiding damage to the crushing knife roller 2 caused by continuous extrusion of larger foreign matter.

[0050] At the same time, when the crushing disengagement is performed, the right movement of the linkage strip 10 will drive the movement strip 12 to move right, the movement strip 12 drives the displacement shaft 13 to move right, the displacement shaft 13 drives the two sliding rings 20 to move right, and the two sliding rings 20 slide right on the displacement sleeve strip 14. Thus, the displacement shaft 13 moves forward along the inside of the movement inclined chute 15 under the action of the inclined guide of the movement inclined chute 15, the displacement shaft 13 drives the displacement sleeve strip 14 to move forward, the displacement sleeve strip 14 slides forward along the upper surface of the crushing recovery box 1, and at the same time, the displacement sleeve strip 14 drives the sleeve sliding block 28 to move forward, the sleeve sliding block 28 moves forward along the outer wall of the guide column 29, and at the same time, the sleeve sliding block 28 also moves forward along the inner wall of the guide frame 30. The guide frame 30 is supported by the crushing recovery box 1, the guide frame 30 supports the guide column 29, and the stability of the guide column 29 is increased.

[0051] The displacement sleeve strip 14 drives the two inclined strips 16 to move stably forward, the inclined strips 16 drive the moving rollers 17 to move forward, the moving rollers 17 drive the fixed knives 18 to move forward, the fixed knives 18 start to move away, so that the distance between the fixed knives 18 and the crushing knife rollers 2 becomes larger, so that the fixed knives 18 start to move away from the larger foreign matters, so that the fixed knives 18 no longer contact the larger foreign matters, so that the gap between the fixed knives 18 and the crushing knife rollers 2 becomes larger, at the same time, the larger foreign matters automatically fall out along the larger gap between the crushing knife rollers 2 and the fixed knives 18, avoiding the foreign matters from being continuously stuck in the gap between the fixed knives 18 and the crushing knife rollers 2, not only avoiding the damage of the fixed knives 18 and the crushing knife rollers 2, but also avoiding the damage caused by the continuous excessive load of the crushing motor 25.

In the technical solution, the electric appliance control elements not mentioned belong to the prior art, so they are not shown in the drawings and will not be described here.
