[0002] Among the industrial hazardous wastes, waste paint barrels, coating barrels, waste oil barrels and resin waste iron barrels are all hazardous wastes. Waste paint barrels usually have some waste paint, coatings, waste oil and other hazardous wastes left in them. Once leaked, they will pollute the soil and human health. Generally, waste paint barrels have waste paint (including benzene, etc.) left in them, which will have an impact on human health. If waste paint barrels are illegally burned, the pungent smell will cause serious harm to the surrounding environment and residents.

[0003] At present, in the processing of these packaging barrels, when the complete packaging barrels are cleaned, the residues in the packaging barrels cannot be completely removed.

[0035] Preferably, the method for treating hazardous waste barrels by using the hazardous waste barrel cleaning and crushing device as described above comprises the following steps:

[0036] S1. First, the packaging barrel to be processed is transported to the release mechanism position through the conveying pipe. When the two arc-shaped fan ring plates in the release mechanism approach each other downward, one of the packaging barrels will fall into the support between the two arc-shaped fan ring plates. Then, when the two arc-shaped fan ring plates approach each other upward, a packaging barrel constrained between the two arc-shaped fan ring plates will fall onto the material support plate.

[0037] S2. A suction cup support plate connected to the inner rod end of the electric telescopic rod has multiple suction cups, and the multiple suction cups are adsorbed on the bottom of the packaging barrel that falls on the material support plate;

[0038] The inner rod of the electrically controlled telescopic rod extends, driving the packaging barrel to move toward the shear mechanism support seat close to the shear mechanism. In the initial state, each pair of shear support plates are at a position away from each other, so that the side wall of the packaging barrel is between each pair of shear support plates of the shear mechanism, and the end of the shear support plate connected to the shear roller is close to the bottom of the packaging barrel;

[0039] S3, the first motor drives the first threaded driving rod to rotate through the meshing first driving gear and the first driven gear, and the first threaded driving rod and the first threaded hole on the shear sliding block are threadedly matched to make the two shear sliding blocks slide in the shear sliding housing and approach each other, thereby making the shear support plates connected to the shear sliding blocks approach each other, and the shear rollers connected to the ends of each pair of shear support plates approach each other to cut the side wall of the packaging barrel;

[0040] S4, the inner rod of the electric telescopic rod retracts, driving the packaging barrel to move toward the support column. During the movement of the packaging barrel, the two shear rollers that cooperate with each other on each pair of shear support plates cut the side wall of the packaging barrel into strips;

[0041] S5. After the side wall of the packaging barrel is cut, the inner rod of the electric telescopic rod extends to drive the packaging barrel to move toward the shear mechanism support seat close to the shear mechanism, so that the shear rollers connected to the ends of the multiple pairs of shear support plates in the shear mechanism clamp the packaging barrel together, and the servo motor drives the rotary support ring to rotate and drives the shear mechanism support seat to rotate together with the clamped packaging barrel, so that the packaging barrel moves to a coaxial position with the adjacent electric telescopic rod, and the inner rod of the electric telescopic rod extends so that the multiple suction cups on the suction cup support plate are adsorbed on the bottom of the packaging barrel, and then the inner rod of the electric telescopic rod retracts to drive the packaging barrel to be unloaded from between the multiple pairs of shear support plates;

[0042] S6, the servo motor drives the rotary support ring to rotate, and the rotary support ring of the expansion and flattening mechanism is in a coaxial position with the packaging barrel cut in step S4, and the inner rod of the electric control telescopic rod extends to drive the packaging barrel to move toward the expansion and flattening mechanism;

[0043] When the side wall of the packaging barrel surrounds the multiple top pressure fan rings, the second motor drives the second threaded driving rod to rotate through the meshed second driving gear and the second driven gear, and the second threaded driving rod drives the flattening sliding block to slide in the flattening sliding housing, so that the flattening sliding block moves together with the flattening support plate toward the edge of the flattening mechanism support seat, and the extension of the inner rod of the electric control telescopic rod also drives the packaging barrel to continue to move toward the expansion flattening mechanism;

[0044] The pressing fan rings at the end of the flat support plate are in pressing contact with the inner side wall of the packaging barrel. Driven continuously by the electric control telescopic rod, multiple pressing fan rings cause the side wall of the packaging barrel cut into strips to turn outwards, and finally make the side wall of the packaging barrel cut into strips be in the same plane as its own bottom;

[0045] S7. The inner rod of the electric control telescopic rod retracts to drive the packaging barrel processed in step S6 to move above the material flow groove, and multiple suction cups release the packaging barrel. The packaging barrels processed in step S6 are centrally collected in the material storage box;

[0046] S8. Crush the packaging barrels collected in the material storage box by using a crusher to obtain relatively flat packaging barrel fragments.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably designed and easy to operate. First, the shearing mechanism can cut the side wall of the packaging barrel into regular strips, then the expansion and flattening mechanism turns the side wall of the packaging barrel outwards so that the strip-shaped side wall of the packaging barrel is approximately in the same plane as the bottom of the packaging barrel. Finally, the crusher is used to crush the packaging barrel into relatively flat fragments, which is convenient for removing the residues on the packaging barrel. At the same time, the shearing mechanism also has a cleaning function, which is convenient for thoroughly cleaning the inner and outer side walls of the packaging barrel.

[0087] S5. After the side wall of the packaging barrel is cut, the inner rod of the electric telescopic rod 14 extends to drive the packaging barrel to move toward the shear mechanism support seat 21 close to the shear mechanism 20, so that the shear rollers 221 connected to the ends of the multiple pairs of shear support plates 22 in the shear mechanism 20 clamp the packaging barrel together, and the servo motor drives the rotary support ring 12 to rotate and drives the shear mechanism support seat 21 to rotate together with the clamped packaging barrel, so that the packaging barrel moves to a coaxial position with the adjacent electric telescopic rod 14, and the inner rod of the electric telescopic rod 14 extends to make the multiple suction cups 142 on the suction cup support plate 141 adsorbed on the bottom of the packaging barrel, and then the inner rod of the electric telescopic rod 14 retracts to drive the packaging barrel to be unloaded from between the multiple pairs of shear support plates 22;

[0088] S6, the servo motor drives the rotary support ring 12 to rotate, and the rotary support ring 12 of the expansion and flattening mechanism 30 is in a coaxial position with the packaging barrel cut in step S4, and the inner rod of the electric control telescopic rod 14 is extended to drive the packaging barrel to move toward the expansion and flattening mechanism 30;

[0089] When the side wall of the packaging barrel surrounds the plurality of top pressure fan rings 319, the second motor 316 drives the second threaded driving rod 314 to rotate through the meshed second driving gear 317 and the second driven gear 318, and the second threaded driving rod 314 drives the flattening sliding block 312 to slide in the flattening sliding housing 311, so that the flattening sliding block 312 moves together with the flattening support plate 32 toward the edge of the flattening mechanism support seat 31, and the extension of the inner rod of the electric control telescopic rod 14 also drives the packaging barrel to continue to move toward the expansion flattening mechanism 30;

[0090] The pressing fan ring 319 at the end of the flat support plate 32 is in pressing contact with the inner wall of the packaging barrel. Under the continuous driving of the electric control telescopic rod 14, the multiple pressing fan rings 319 cause the side wall of the packaging barrel cut into strips to be turned outward, and finally cause the side wall of the packaging barrel cut into strips to be in the same plane with its bottom.

[0091] S7, the inner rod of the electric telescopic rod 14 retracts and drives the packaging barrel processed in step S6 to move above the material flow slot 112, and the multiple suction cups 142 release the packaging barrel, and the packaging barrel processed in step S6 is collected in the material storage box;

[0092] S8. The packaging barrels collected in the material storage box are crushed by a crusher to obtain relatively flat packaging barrel fragments. Example

[0093] The difference from Example 2 is that, in step S4, if the side wall of the packaging barrel needs to be cut into narrower strips, the third motor 153 in the corner mechanism 15 drives the rotating shell 152 to rotate through the meshing third driving gear 154 and the third driven gear ring 155, and the rotating shell 152 drives the entire electric control telescopic rod 14 to deflect, thereby causing the packaging barrel to rotate around its own axis by a certain angle, and then repeating the above steps S2 to S4, the side wall of the packaging barrel can be cut into narrower strips; Example

[0094] The difference from Example 2 is that, taking the paint bucket as an example, if there is still liquid paint remaining in the paint bucket, before step S3, the cleaning liquid is connected to the cleaning liquid input interface 224 through a pipeline, and the cleaning liquid is input into the cleaning liquid input interface 224 and then sprayed out from the multiple cleaning liquid spray holes 223 to clean the inner and outer walls of the paint bucket to remove the remaining liquid paint and partially solidified paint residues in the paint bucket. The cleaned paint bucket is dried and then returned to the delivery pipe 41, and then processed through steps S1 to S8. Example

[0095] The difference from Example 2 is that after step S8, the packaging barrel fragments are processed by a vibration grinder to remove residues on the packaging barrel fragments.
