However, the automatic screening system for industrial explosives still has problems such as few types and poor flexibility. Therefore, this technology mainly solves the automatic screening operation for the dismantling and recycling of retired TNT, making it convenient for recycling.

[0003] In the existing public documents, the patent with patent announcement number CN211035751U discloses an automatic powdered explosive stripping machine.

[0010] When this technology is used, the contraction electric cylinder pushes the connection plate upward, and the connection plate drives the extrusion support bar upward, and a large gap is generated between the cover plate and the vibration screening box, so that the retired TNT dismantling and recycling raw materials can be placed inside the vibration screening box, and the connection plate is retracted by starting the contraction electric cylinder to move downward, and the extrusion support bar makes the cover plate move downward, and the pressure block is squeezed on the pressure sensor. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the contraction electric cylinder is closed by the controller, and the cover plate immediately performs vibration screening, the driving motor drives the driving pulley to rotate, the transmission belt drives the large pulley to rotate, and the large pulley drives the rotating shaft to rotate inside the bearing sleeve, and at the same time the rotating shaft drives the articulated sleeve rod to rotate and vibrate, the articulated sleeve rod drives the vibration screening box to move back and forth, and the vibration screening box drives multiple moving wheels to move back and forth, and the moving wheels move back and forth on the inclined track, so that the retired TNT dismantling and recycling raw materials inside the vibration screening box can vibrate back and forth. At the same time, the large-particle retired TNT dismantling and recycling raw materials will be guided and screened from the inside of the vibration screening box to the accordion box.

[0011] Preferably, the multi-directional detection component includes a linkage electric cylinder fixedly arranged above the pressure block; the linkage electric cylinder is fixedly connected to the cover plate, and a connecting block is installed at the output end of the linkage electric cylinder, and a concave plate is fixedly connected to the lower surface of the connecting block, and two sliding shafts are fixedly connected to the lower surface of the concave plate; the bottom ends of the two sliding shafts are fixedly connected to a transverse dust sensor, the outer wall of the sliding shaft is slidably connected to a guide frame, and the guide frame and the cover plate are fixedly connected; the guide frame is internally rotatably connected to a linkage screw, and a transmission motor is fixedly installed on one side of the guide frame, the outer wall of the linkage screw is threadedly connected to a sliding sleeve rod, and the sliding sleeve rod is slidably connected to the guide frame; a longitudinal dust sensor is fixedly installed at the bottom end of the sliding sleeve rod, the cross-sectional shape of the concave plate is concave, the cross-sectional shape of the two sliding shafts is circular, the outer wall of the sliding shaft is a smooth surface, the transmission motor is used to drive the linkage screw to rotate, and the output end of the transmission motor is fixedly connected to the linkage screw.

[0013] Technical effects and advantages of the present invention: 1. The present invention adopts a safety locking mechanism. The reduction motor drives the screw to rotate, and the screw rotates inside the slide frame. The screw drives the two sleeve blocks to approach each other under the action of the thread transmission force. The two arc-shaped pressure plates are synchronously squeezed at the positions on both sides of the gear roller. The torque sensor senses the torque of the gear roller. When the torque value sensed by the torque sensor is the same as the torque set by the controller, the driving pulley is closed through the controller to avoid dust explosion caused by continued operation of the equipment. The overflowed dust needs to be cleaned before the equipment can be used again, which greatly improves the safety of use.

[0014] 2. The present invention adopts a vibration sealing mechanism component. The contraction electric cylinder pushes the connecting pressure plate to move up, and the extrusion support bar makes the cover plate move up, so that a larger gap is generated between the cover plate and the vibration screening box. By starting the contraction electric cylinder to contract the connecting pressure plate and move it downward, the connecting pressure plate drives the extrusion support bar to move downward, and the pressure block is squeezed on the pressure sensor. The pressure sensor senses the pressure value, and the cover plate and the vibration screening box are firmly sealed to avoid the spillage of the recycled raw material screening after disassembly of retired TNT, and to avoid a large amount of pollution caused by the spillage of dust, which causes safety problems.

[0015] 3. The present invention adopts a multi-directional detection component, which drives the linkage screw to rotate forward and then reversely through the transmission motor. In this way, the linkage screw drives the sliding sleeve to move backward and then forward under the action of the thread. The sliding sleeve drives the longitudinal dust sensor to move backward and then forward. The connecting block drives the concave plate to move right. The concave plate causes the two sliding shafts to move right. The two sliding shafts respectively drive the two transverse dust sensors to move right synchronously. When the dust concentration reaches the value detected by the transverse dust sensor and the longitudinal dust sensor, the linkage electric cylinder and the transmission motor are turned off through the controller, so that the overflowed dust can be known in time, thereby immediately stopping the screening operation, thereby improving the safety of use.

[0016] According to the mutual influence of the above multiple effects, first, the cover plate and the vibration screening box are tightly sealed, and then the two sliding shafts drive the two horizontal dust sensors to move right synchronously, and the dust concentration reaches the value detected by the horizontal dust sensor and the vertical dust sensor. Finally, the driving pulley is closed through the controller to prevent the equipment from continuing to operate and causing dust explosion. In summary, once the amount of powder screened to the outside overflows during the vibration process, it can be detected immediately and the driving operation can be stopped quickly, thereby avoiding the continued vibration that causes the external dust concentration to cause safety problems.

[0034] The operating principle of the automatic screening mechanism for dismantling and recycling retired TNT of the present invention is as follows: Step 1, during vibration sealing, the controller 11 is used to start the contraction electric cylinder 23, which pushes the connecting plate 24 to move upward, and the connecting plate 24 drives the extrusion support bar 25 to move upward, and the extrusion support bar 25 makes the cover plate 19 move upward, and a large gap is generated between the cover plate 19 and the vibration screening box 18, so that the retired TNT dismantling and recycling raw materials can be placed inside the vibration screening box 18, and the connecting plate 24 is contracted by starting the contraction electric cylinder 23 to move downward, and the connecting plate 24 drives the extrusion support bar 25 to move downward, and the extrusion support bar 25 makes the cover plate 19 move downward, and the cover plate 19 drives the pressure block 26 to move downward, and the pressure block 26 is squeezed on the pressure sensor 27, and the pressure sensor 27 senses the pressure value. When the pressure value sensed by the pressure sensor 27 is the same as the pressure value set by the controller 11, the contraction electric cylinder 23 is closed by the controller 11, so that the cover plate 19 and the vibration screening box 18 are firmly sealed, and the cover plate 19 immediately performs vibration screening.

[0035] Step 2, during screening, the driving motor 16 is started through the controller 11, the driving motor 16 drives the driving pulley 15 to rotate, the driving pulley 15 drives the transmission belt 14 to transmit, the transmission belt 14 drives the large pulley 13 to rotate, the large pulley 13 drives the rotating shaft 2 to rotate inside the bearing sleeve 12, and at the same time the rotating shaft 2 drives the articulated sleeve rod 17 to rotate and vibrate, the articulated sleeve rod 17 drives the vibration screening box 18 to move back and forth, the vibration screening box 18 drives multiple moving wheels 20 to move back and forth, the moving wheels 20 move back and forth on the inclined track 21, so that the retired TNT dismantling and recycling raw materials inside the vibration screening box 18 can vibrate back and forth.

[0036] At the same time, large particles of retired TNT dismantling and recycling raw materials will be guided from the inside of the vibration screening box 18 to the accordion box 22 for screening, while small particles of retired TNT dismantling and recycling raw materials can be tilted and discharged downward through the filtration inside the vibration screening box 18, thus achieving an automatic screening operation.

[0037] Step three, during multi-directional detection, when a lot of dust overflows from the connection between the cover plate 19 and the vibrating screening box 18, the transmission motor 35 drives the linkage screw 34 to rotate forward and then reverse, so that the linkage screw 34 drives the sliding sleeve 36 to move backward and then forward under the action of the thread, and the sliding sleeve 36 moves backward and then forward along the inner wall of the guide frame 33, so that the sliding sleeve 36 drives the longitudinal dust sensor 37 to move backward and then forward, so that the longitudinal dust sensor 37 realizes reciprocating movement, thereby realizing longitudinal dust movement.

[0038] The connecting block 29 is driven to move rightward by the linkage electric cylinder 28, and the connecting block 29 drives the concave plate 30 to move rightward, and the concave plate 30 causes the two sliding shafts 31 to move rightward, and the two sliding shafts 31 move rightward along the inner wall of the guide frame 33, and the two sliding shafts 31 respectively drive the two transverse dust sensors 32 to move rightward synchronously, and the two transverse dust sensors 32 detect the dust concentration transversely. When the dust concentration reaches the value detected by the transverse dust sensor 32 and the longitudinal dust sensor 37, the linkage electric cylinder 28 and the transmission motor 35 are turned off by the controller 11.

[0039] Step 4. When locking safely, start the reduction motor 8 through the controller 11, and the reduction motor 8 starts the screw 5 to rotate. The screw 5 rotates inside the slide frame 4, and the screw 5 drives the two sleeve blocks 6 to approach each other under the action of the thread transmission force. The two sleeve blocks 6 respectively drive the two arc pressure plates 7 to approach each other, and the two arc pressure plates 7 are synchronously squeezed at the positions on both sides of the gear roller 3, so that the gear roller 3 can be squeezed and decelerated. At the same time, the torque sensor 9 realizes torque sensing of the gear roller 3, and the support frame 10 can provide stable support for the torque sensor 9. When the torque value sensed by the torque sensor 9 is the same as the torque set by the controller 11, the drive pulley 15 is closed again through the controller 11, so that after the rotating shaft 2 loses power, the vibration screening box 18 is quickly stopped.
