Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-11 , the present invention provides a technical solution: Embodiment 1: A skid-mounted confidential carrier destruction equipment, comprising a skid-mounted frame 34.

The feeding and crushing box 1 is used to crush confidential items to be destroyed. The melting box 22 is connected to the feeding and crushing box 1. Two rollers 2 are arranged in the feeding and crushing box 1. Both ends of the rollers 2 are fixedly connected to connecting shafts 24. The connecting shafts 24 are movably connected to the feeding and crushing box 1. Several grinding mechanisms are arranged in the rollers 2. One end of the grinding mechanism extends into the feeding and crushing box 1, and the other end extends into the inner side of the rollers 2. A semicircular squeezing roller 3 is arranged on the inner side of the rollers 2. One side of the semicircular squeezing roller 3 is arranged in a circular shape, and the other side is arranged in a horizontal shape. One end of the semicircular squeezing roller 3 is movably connected to the roller 2, and the other end passes through the connecting shaft 24 and extends into the external environment, and is fixedly connected to the support plate 19. The semicircular squeezing roller 3 is fixedly connected to the support plate 19 so that the semicircular squeezing roller 3 will not rotate with the roller 2 when it rotates. The support plate 19 is fixedly connected to the outside of the feeding and crushing box 1. The roller 2 rotates to drive several grinding mechanisms to move. When the grinding mechanism moves to the position of the semicircular squeezing roller 3, one end of the grinding mechanism will extend outward, and the roller 2 drives the semicircular squeezing roller 3 to rotate. The extended end of the material-grinding mechanism rotates to crush the material entering between the two rollers 2. The material-grinding mechanism is connected to the material-sucking mechanism, which is arranged inside the roller 2. When one end of the material-grinding mechanism is extended, the material-sucking mechanism rotates and adsorbs the metal on the surface of the roller 2. When one end of the material-grinding mechanism is retracted, the material-sucking mechanism rotates to cancel the adsorption of the metal. The backs of the two rollers 2 are in contact with the scraper 4, which is fixedly connected to the inner wall of the feeding and crushing box 1. The scraper 4 can scrape off the metal crushed pieces adhering to the surface of the roller 2. A material guide pipe 39 is provided at the lower side of the two rollers 2, and both ends of the material guide pipe 39 are fixedly connected to the inner side of the feeding and crushing box 1. The material guide pipe 39 is used to collect and guide the non-metallic crushed parts. Two metal melting boxes 9 are fixedly connected in the melting box 22. The metal melting box 9 is used to store and melt the metal crushed parts. A non-metal melting box 8 is fixedly connected between the two metal melting boxes 9.

When the material is crushed, the crushed material will pass through the sealing mechanism and enter the metal melting box 9 and the non-metal melting box 8. When the material is melted, the sealing mechanism will be closed. The metal melting box 9 and the non-metal melting box 8 are made of high-temperature resistant ceramics, and the high-temperature resistant ceramics can be selected from silicon carbide ceramics or alumina ceramics.

[0019] Embodiment 2: On the basis of Example 1, in order to separate the metal crushed pieces and the non-metal crushed pieces, the material grinding mechanism includes a cross-shaped material grinding rod 25, the cross-shaped material grinding rod 25 is slidably connected to the connecting cavity 31, the connecting cavity 31 is opened in the roller 2, one end of the cross-shaped material grinding rod 25 extends into the feeding and crushing box 1, and the other end extends into the roller 2.

A toothed rod 26 is fixedly connected to one side of the cross-shaped material-grinding rod 25, and the toothed rod 26 is connected to the material suction mechanism at the side away from the cross-shaped material-grinding rod 25. When the roller 2 drives the cross-shaped material-grinding rod 25 to move to the position of the semicircular squeezing roller 3, the cross-shaped material-grinding rod 25 will be squeezed and moved outward, so that the connecting spring 23 is compressed. When the material is put into the feeding and crushing box 1, the material will enter between the two rollers 2 and be squeezed, and the cross-shaped material-grinding rod 25 extending outward will crush the material. The material suction mechanism includes a connecting column 29, which is movably connected to a clearance cavity 30, which is provided in the roller 2, and is communicated with the connecting cavity 31. Two magnetic blocks 27 are fixedly connected to one side of the connecting column 29, and a tooth groove 28 is provided in the middle of the outer side of the connecting column 29, which meshes with the gear rod 26. A ceramic sheet 20 is fixedly connected to the clearance cavity 30. When the gear rod 26 moves, the connecting column 29 will start to rotate accordingly. The rotation of the connecting column 29 causes the magnetic block 27 to move from the position of the ceramic sheet 20 to contact with the roller 2. At this time, the metal substances in the crushed material will be adsorbed on the surface of the roller 2, and the non-metallic substances will fall downward into the guide tube 39. The blocking mechanism includes a ceramic blocking plate 21, and a plurality of through holes 18 are respectively provided at the upper end of the ceramic blocking plate 21 for the material to pass through. A gear ring 6 is fixedly connected to the outer side of the ceramic blocking plate 21, and the gear ring 6 is movably connected to the melting box 22. The outer side of the gear ring 6 is meshed with the gear 13, and the gear 13 is fixedly connected to the output end of the motor 5. The motor 5 is fixedly installed in the melting box 22. When the motor 5 is turned on, the gear 13 starts to rotate, and the gear 13 rotates to drive the gear ring 6 to rotate. The gear ring 6 rotates to drive the ceramic blocking plate 21 to rotate, so that the ceramic blocking plate 21 isolates the feeding and crushing box 1 from the melting box 22. A spiral guide is provided in the melting box 22. Liquid chamber 10, one end of the spiral liquid guiding chamber 10 is fixedly connected to the output end of the water pump 36 through the conduit 11, and the other end is also connected to the cooling water tank 32 through the conduit 11. The water pump 36 is fixedly connected to the skid-mounted frame 34, and the input end of the water pump 36 is connected to the cooling water tank 32. In the process of melting and destroying the material, the water pump 36 is started to pump the cooling water in the cooling water tank 32 into the conduit 11, and the cooling water entering the conduit 11 will enter the spiral liquid guiding chamber 10. The cooling water flows in the spiral liquid guiding chamber 10 to cool the melting box 22, and the cooling water will eventually be discharged back into the cooling water tank 32 through another conduit 11; A high-temperature plasma torch burner 12 is fixedly connected to the inner side of the metal melting box 9 and the non-metal melting box 8. The high-temperature plasma torch burner 12 is connected to the delivery pipe 14. One end of the delivery pipe 14 is fixedly connected to the melting box 22, and the other end is fixedly connected to the fuel tank 33. The fuel tank 33 is fixedly installed in the skid frame 34. The fuel is delivered to the high-temperature plasma torch burner 12 through the fuel tank 33. The metal in the metal melting box 9 is melted by the high-temperature plasma torch burner 12, and the non-metal melting box 8 is melted. The non-metallic materials in 8 are melted, and a smoke guide cavity 7 is provided in the melting box 22. One end of the smoke guide cavity 7 is communicated with the inner cavity of the melting box 22, and the other end is connected to the smoke exhaust pipe 37. One end of the smoke exhaust pipe 37 is fixedly connected to the melting box 22, and the other end is connected to the smoke treatment device 35. The smoke treatment device 35 is fixedly installed in the skid-mounted frame 34. The smoke generated by the melting enters the smoke exhaust pipe 37 through the smoke guide cavity 7. The smoke entering the smoke exhaust pipe 37 enters the smoke treatment device 35 and is discharged after being processed. The flue gas treatment device 35 includes a flue gas cooling tower, a flue gas cooling circulation pump, a water tank, a water circulation cooling pipeline, a flue gas pipeline, a traction fan, a lead and heavy metal removal device, and a dry desulfurization and denitrification tower; the flue gas route: the smoke in the furnace is sequentially treated and discharged after passing through the flue gas pipeline, the cooling tower, the flue gas pipeline, the traction fan, the flue gas pipeline, the lead and heavy metal removal device, the flue gas pipeline, and the dry desulfurization and denitrification device; One side of the connecting shaft 24 extends into the external environment and is fixedly connected to the transmission gear 15. The two transmission gears 15 are meshed with each other. A transmission motor 17 is fixedly connected to one side of the feeding and crushing box 1. The output end of the transmission motor 17 is fixedly connected to a connecting gear 16. The connecting gear 16 is meshed with the transmission gear 15. Turning on the transmission motor 17 drives the connecting gear 16 to rotate counterclockwise. The counterclockwise rotation of the connecting gear 16 drives the transmission gear 15 meshed with it to rotate clockwise. At this time, the two rollers 2 rotate in opposite directions. A box door 38 is movably connected to one side of the melting box 22. The operator can take out the molten metal or non-metallic material by opening the box door 38.

[0020] Working principle: when in use, turn on the transmission motor 17 to drive the connecting gear 16 to rotate counterclockwise, and the connecting gear 16 rotates counterclockwise to drive the transmission gear 15 meshing with it to rotate clockwise. At this time, the two rollers 2 rotate in opposite directions. Since the opposite surfaces of the two semicircular squeezing rollers 3 are both arranged in an arc shape, when the roller 2 drives the cross-shaped material grinding rod 25 to move to the position of the semicircular squeezing roller 3, the cross-shaped material grinding rod 25 will be squeezed and moved outward, so that the connecting spring 23 is compressed. When the material is put into the feeding and crushing box 1, the material will enter between the two rollers 2 and be squeezed, and the cross-shaped material grinding rod 25 extending outward will crush the material; At the same time, the cross-shaped material-grinding rod 25 will drive the gear rod 26 to move during its movement. Since the gear rod 26 is meshed in the tooth groove 28, the connecting column 29 will start to rotate as the gear rod 26 moves. The connecting column 29 rotates so that the magnetic block 27 moves from the position of the ceramic sheet 20 to contact with the roller 2. At this time, the metal substances in the crushed material will be adsorbed on the surface of the roller 2, and the non-metallic substances will fall downward into the guide tube 39. When the adsorbed metal leaves the position of the guide tube 39, the cross-shaped material-grinding rod 25 at the corresponding position will no longer be squeezed by the semicircular squeezing roller 3. Under the elastic force of the connecting spring 23, the cross-shaped material-grinding rod 25 will move inward. At this time, the magnetic block 27 connected to the outer side of the connecting column 29 will rotate to the position of the ceramic sheet 20. At this time, the metal will fall downward into the feeding and crushing box 1 under the action of the scraper 4. The non-metallic material entering the guide pipe 39 will pass through the through hole 18 and enter the non-metallic melting box 8, and the metal material entering the feed crushing box 1 will pass through the through hole 18 and enter the metal melting box 9. At this time, the motor 5 is turned on to drive the gear 13 to start rotating, and the gear 13 rotates to drive the gear ring 6 to start rotating, and the gear ring 6 rotates to drive the ceramic sealing plate 21 to rotate, so that the ceramic sealing plate 21 isolates the feed crushing box 1 from the melting box 22, and fuel is transported to the high-temperature plasma torch burner 12 through the fuel tank 33. The high-temperature plasma torch burner 12 melts the metal in the metal melting box 9 and melts the non-metallic material in the non-metal melting box 8. The generated smoke enters the exhaust pipe 37 through the smoke guide cavity 7, and the smoke entering the exhaust pipe 37 enters the flue gas treatment device 35 to be processed and then discharged; At the same time, in the process of melting and destroying the materials, the water pump 36 is started to pump the cooling water in the cooling water tank 32 into the conduit 11. The cooling water entering the conduit 11 will enter the spiral liquid guide cavity 10. The cooling water flows in the spiral liquid guide cavity 10 to cool the melting box 22. The cooling water will eventually be discharged back into the cooling water tank 32 through another conduit 11. The operator can take out the molten metal or non-metallic material by opening the box door 38.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
