When the petroleum coke is not fully burned, it will produce the characteristics of coking and sticking after being heated again, which can more directly prompt the staff. Once the petroleum coke is not fully calcined, high temperature will be generated due to the crushing and friction of the crushing roller 102, which will cause the petroleum coke to coking and adhere to the crushing roller 102. At the same time, the use of the swing rod 603 is also convenient for scraping and cleaning the electric heating plate 6011.

[0025] The working principle of the embodiment is as follows: first, when the device is not crushing, at this time, the bottom of the rotary arm 203 is attached to the two power connection rings 202 by extrusion of the reset spring 205, at this time, the upper electromagnet 303 and the lower electromagnet 304 are magnetically attracted to each other after being powered on, and the two rotating baffles 302 are turned upward, realizing that the two rotating baffles 302 are in a closed state; when crushing is needed, the control hydraulic cylinder 402 pushes the power-off control frame 401 forward, driving the rear crushing roller 102 and the rear first motor 103 to move forward, and the front crushing roller 102 is close to the rear crushing roller 102, at this time, the power connection block 403 no longer extrudes the two distance switches 502, realizing the control of the two first motors 103 to start driving the two crushing rollers 102 to rotate and crush, when the two first motors 103 are powered on and rotate, at this time, as the rotating speed of the front crushing roller 102 gradually increases, when the rotating speed reaches the standard, the centrifugal force gradually increases, the front crushing roller 102 drives the rotary arm 203 to rotate, and the centrifugal force of the counterweight block at the top of the counterweight rod 204 moves the counterweight rod 204 to one side of the counterweight block, compressing the reset spring 205, at this time, the counterweight rod 204 is no longer attached to the two power connection rings 202, at this time, the two power connection rings 202 cannot be normally turned on, the upper electromagnet 303 and the lower electromagnet 304 are no longer magnetically attracted to each other, at this time, petroleum coke can be normally put on the two rotating baffles 302, under the action of its own weight, the petroleum coke will press the two rotating baffles 302 to form an opening, realizing that the material is crushed by the two crushing rollers 102, as the petroleum coke on the two rotating baffles 302 falls onto the two crushing rollers 102, cooperating with the torsional spring on the baffle shaft 3021, realizing the control of the two rotating baffles 302 to flip and reset to shield and protect, the structure is more reasonable, ensuring that the two crushing rollers 102 are preferentially started when crushing, when the crushing needs to be stopped, the control hydraulic cylinder 402 needs to be controlled to drive the power-off control frame 401 to be pulled back, until the two crushing rollers 102 are separated to the maximum distance, at this time, the power connection block 403 is also driven to extrude the two distance switches 502, realizing the control of the two first motors 103 to be powered off and stopped, at this time, if there is petroleum coke that has not been crushed yet between the two crushing rollers 102, it can be directly discharged from between the two crushing rollers 102, and the head and tail materials can be crushed again. As the crushing roller 102 crushes and discharges petroleum coke, it is guided by the discharge inclined plane 601 to be discharged from the opening provided on the bottom side of the crushing installation shell 101, the second motor 602 can be controlled to drive the swing rod 603 to rotate, promoting the discharge of the material, at the same time, the swing rod 603 can scrape and clean the surface of the electric heating plate 6011, the staff can periodically control the electric heating plate 6011 to be powered on and heated, and the second motor 602 is stopped, when the petroleum coke on the surface of the electric heating plate 6011 is not calcined well, coking will occur and adhere to the electric heating plate 6011, the staff can directly observe the coking and bonding condition of the surface of the electric heating plate 6011 to judge whether the petroleum coke of this batch will adhere to the crushing roller 102, the structure is more reasonable.
