[0021] The method of using a pulverizer for petroleum coke production includes the following steps:

[0022] S1: The user puts the raw material to be crushed into the feed port of the support shell, and the servo motor is activated. The servo motor will drive the upper crushing body and the inner shell to rotate synchronously through the transmission rod. At this time, the inner shell drives the middle shell to rotate through the second limit plate, and the middle shell drives the outer shell to rotate through the first limit plate, so that the connecting gear ring on the outer wall of the outer shell can drive the inner gear ring to rotate through the second gear rod. At this time, the inner gear ring will drive the lower crushing body and the processing block to rotate in the opposite direction. In this process, the upper crushing body and the lower crushing body will constitute a primary raw material crushing structure to crush the raw material entering the support shell, and the processing block, the outer shell, the inner shell and the middle shell will constitute a subsequent secondary raw material crushing structure;

[0023] S2: During the rotation of the upper crushing body, the upper crushing body will drive the rotating ring to rotate synchronously, and the rotating ring will drive the pressing plate and the moving plate to rotate along the inner wall of the supporting shell. At this time, the force rod at the end of the moving plate will move along the wavy guide groove, so that the force rod can drive the moving plate and the toothed plate frame to move back and forth synchronously, and the toothed plate frame will drive the transmission gear and the cam to rotate back and forth, and the cam will drive the two ends of the pressing plate to swing back and forth, and the pressing plate will apply a horizontal thrust to the raw materials in the supporting shell to push the raw materials to the inclined surface of the upper crushing body, thereby improving the efficiency of the materials being crushed by the lower crushing body and the upper crushing body;

[0024] S3: During the movement of the tooth plate frame, the two thrust plates fixedly installed on the tooth plate frame will move synchronously, so that the inclined surface of the thrust plate can apply thrust to the cross bar. At this time, the cross bar will drive the lifting rod to move upward, and the sliding block on the top of the lifting rod will slide synchronously on the inner wall of the rotating ring, and the lifting rod will drive the bottom positioning ring to move upward synchronously. The positioning ring will further compress the reset spring, and at the same time, the moving frame rotatably connected between the two positioning rings will move upward synchronously, and the moving frame drives the corresponding first gear rod to rotate through the vertical tooth plates on both sides, and the first gear rod will drive the extrusion block to rotate, so that the extrusion block can support the raw materials in the shell to apply vertical thrust, thereby further improving the raw material crushing efficiency;

[0025] S4: The material crushed by the lower crushing body and the upper crushing body falls under the processing block. At this time, the device controls the electric cylinder to move back and forth. The moving end of the electric cylinder drives the middle shell to move through the inner shell and the second limit plate, and the middle shell drives the outer shell to move through the first limit plate, so that the rotating outer shell, middle shell and inner shell can exert pressure on the material at the bottom of the processing block to achieve further crushing of the material. Then the device controls the electric cylinder to move downward, and the control electric cylinder will drive the inner shell to move downward, so that the inner shell no longer blocks the mesh of the second sieve ring, and the inner shell will drive the middle shell to move downward through the second limit plate, so that the middle shell no longer blocks the first sieve ring. At this time, the rotation of the outer shell, inner shell and middle shell will discharge the material with qualified particle size through the first sieve ring and the second sieve ring. The device then controls the electric cylinder to reset, and the processed material will be discharged through the discharge inclined plate.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the pulverizer and the use method for petroleum coke production are provided with a two-stage fine pulverization structure. During the use of the device, pressure can be applied to the material through a multi-directional material pressing structure, thereby improving the processing efficiency of the device pulverization structure, and the device can quickly discharge materials of qualified volume. The specific contents are as follows:

[0027] The cam is rotatably mounted on the inner wall of the rotating ring, and a pressing plate with equal angle distribution is rotatably embedded therein. The upper and lower surfaces of the middle part of the pressing plate are fixedly connected with convex shafts, which are rotatably embedded in the inner wall of the rotating ring, so that the pressing plate can reciprocate on the rotating ring to horizontally extrude the material, and a moving frame is rotatably and closely mounted on the side wall of the lower end of the lifting rod, and symmetrically distributed positioning rings are arranged on the upper and lower sides of the moving frame, and the positioning ring is fixedly sleeved on the outer wall of the lifting rod, and corresponding vertical tooth plates are fixedly mounted on the ends of the branch plates on both sides of the moving frame, and the gears of the first gear rod are meshed on the sides of the vertical gear plate, and the rod body of the first gear rod is fixedly penetrated through the extrusion block setting, and the extrusion block is rotatably embedded in the mounting groove on the inner side of the pressing plate, so that the lifting rod can drive the moving frame to reciprocate up and down through the positioning ring, and the moving frame will drive the two vertical tooth plates to move synchronously, and at this time the vertical tooth plate will drive the first gear rod and the extrusion block to rotate, so that the extrusion block can further push the material;

[0028] 2. A first sieve ring is coaxially fixedly installed on the inner wall of the outer shell, and the mesh on the top of the first sieve ring is fitted on the outer wall of the middle shell. A first limit plate is fixedly connected to the middle of the outer wall of the middle shell, and the first limit plate passes through the through-groove at the lower part of the first sieve ring. One end of the first limit plate away from the first limit plate is slidably embedded in the inner wall of the outer shell, and a moving end of the electric cylinder is coaxially rotatably embedded at the bottom end of the inner shell. A second limit plate is fixedly connected to the outer wall of the inner shell, and the second limit plate fits through the through-groove at the lower part of the second sieve ring. The end of the limiting plate is slidably installed in the slide groove on the inner wall of the middle shell, the top of the second sieve ring is coaxially fixedly connected to the inner wall of the middle shell, and the inner wall of the second sieve ring is fitted on the outer wall of the inner shell. When the electric cylinder drives the inner shell to move, the inner shell will drive the middle shell to move synchronously through the second limiting plate, so that the first sieve ring and the second sieve ring are exposed. At this time, the material with qualified volume will be discharged through the first sieve ring and the second sieve ring. When the middle shell and the inner shell are reset, they also have the function of cleaning the first sieve ring and the second sieve ring. BRIEF DESCRIPTION OF THE DRAWINGS
