Description

Technical Field

[0001] This invention relates to the field of radioactive contamination cleanup technology, and in particular to a decontamination device for radioactive hazardous materials transport equipment. Background Technology

[0002] Radioactive hazardous materials transport equipment is a complete set of specialized equipment specifically designed for the containment, transport, monitoring, and protection of radioactive materials. It provides comprehensive protection against radiation leakage, criticality risks, impact damage, and contamination spread. The equipment covers five major systems: packaging and carrying, transport carrier, radiation detection, personnel protection, and emergency support. It is widely used in various radioactive hazardous materials transfer scenarios, such as medical radionuclides, industrial radioactive sources, nuclear fuel, and radioactive waste.

[0003] Most vehicles used to transport radioactive hazardous materials are box trucks. After the hazardous materials are transported, the solid waste adhering to the inner walls of the truck needs to be cleaned using cleaning equipment.

[0004] During use, existing technologies mostly involve washing the carriage or sucking up impurities when cleaning solid waste from the inner walls of the carriage. However, washing the carriage generates a large amount of wastewater containing radioactive contaminants. This radioactive wastewater can spread the contaminants and is difficult to collect. When sucking up impurities, the suction pipe has difficulty getting close to the impurities in the corners and edges of the carriage due to the obstruction of the carriage. Therefore, impurities in the corners and edges of the carriage are not easy to suck up. Impurities that are tightly adhered to the inner walls of the carriage are also difficult to suck up.

[0005] Based on this, the present invention designs a decontamination device for radioactive hazardous materials transportation equipment to solve the above problems. Summary of the Invention

[0057] Specifically, the material passage component 32 includes a first material passage pipe 321, which is disposed at the end of the horizontal spray pipe 233.

Spray nozzles 323 are disposed on the side walls of the vertical spray pipe 231 and the horizontal spray pipe 233.

[0058] The first cylinder 224 and the second cylinder 237 are disposed on the inner wall of the rotating drum 311, the ventilation support pipe 213 passes through the rotating drum 311, and the horizontal glue spraying pipe 233 passes through the rotating drum 311.

[0059] Furthermore, the first material passage pipe 321 is fixedly connected to the end of the horizontal spray pipe 233 away from the vertical spray pipe 231.

[0061] Both the first feed pipe 321 and the second feed pipe 322 are heated conveying hoses;

[0062] The gel-like substance inside the first feed pipe 321 and the second feed pipe 322 and sprayed onto the inner wall of the carriage by the spray head 323 is adhesive.

[0063] The adhesive used is hot melt pressure-sensitive adhesive (PSA);

[0064] When in use, when it is necessary to clean solid impurities contaminated with radioactive pollution from the inner wall of the carriage, drive the vehicle onto the support seat 1, and drive the vehicle onto the adhesive plate on the support plate 211 to the middle position of the innermost inner wall of the carriage. At this time, the adhesive is filled into the vertical spray tube 231 through the second feed tube 322. The adhesive is sprayed onto the inner wall of the carriage through the spray nozzle 323. At this time, the motor 314 is started, and the motor 314 drives the drive gear 313 to rotate. The drive gear 313 drives the rotating drum 311 to rotate through the ring rack 312. The rotating drum 311 drives the vertical spray tube 231 to rotate around the ventilation support tube 213 through the horizontal spray tube 233. At this time, the spray nozzle 323 on the vertical spray tube 231 sprays adhesive onto the innermost inner wall of the carriage. After the vertical spray tube 231 rotates a quarter turn in each direction around the ventilation support tube 213, the adhesive coating of a part of the innermost inner wall of the carriage is completed.

[0065] Then, the first cylinder 224 is activated, which drives the sliding push plate 223 to move closer to the support plate 211. At this time, the sliding push plate 223 drives the cross slider 221 to move closer to the support plate 211 via the connecting rod 222. The cross slider 221 drives the end of the vertical spray tube 231 near the vent support tube 213 to move closer to the support plate 211 via the limiting slide bar 235. At this time, the limiting slide bar 235 moves away from the vent under the limitation of the limiting slide groove 236. The support tube 213 moves in a certain direction. At this time, the vertical spray tube 231 drives the spray head 323 to rotate towards the innermost corner of the carriage. At this time, the motor 314 is started. The motor 314 drives the vertical spray tube 231 to rotate around the ventilation support tube 213. At this time, the adhesive in the vertical spray tube 231 is sprayed and coated towards the innermost corner of the carriage through the spray head 323. After the vertical spray tube 231 rotates one-quarter turn in each direction around the ventilation support tube 213, the spraying of the innermost corner of the carriage is completed.

[0066] After the adhesive is applied to the innermost corner of the carriage, the first cylinder 224 is activated to move the cross slider 221 back to its initial position. Then, the second cylinder 237 is activated, which moves the horizontal spray tube 233 towards the support plate 211. At this time, the vertical spray tube 231 moves the nozzle 323 towards the support plate 211 and the venting support pipe 213. When the horizontal spray tube 233 moves to the point where the nozzle 323 closest to the support plate 211 is located on the inner side of the coated inner wall of the carriage, the motor 314 is activated. The motor 314 moves the vertical spray tube 231 and the horizontal spray tube 233 around the venting support pipe 213. At this time, adhesive is injected into the horizontal spray tube 233 through the first feed tube 321 and into the second feed tube 323. 2. Fill the vertical spray tube 231 with adhesive, and then spray the adhesive onto the inner wall of the carriage through the horizontal spray tube 233 and the nozzle 323 on the vertical spray tube 231. At this time, the nozzle 323 on the horizontal spray tube 233 completes the coating of the front and rear and upper and lower inner walls of the carriage. At the same time, the nozzle 323 on the vertical spray tube 231 coats the outer side of the support plate 211 and coats the outer wall of the ventilation support pipe 213 near the support plate 211. At this time, the inner wall of the carriage outside the support plate 211 is covered with adhesive. The adhesive wraps the support plate 211 and fills the anti-drop groove 212. The adhesive wraps the outer wall of the ventilation support pipe 213 near the support plate 211. At this time, the adhesive can be applied to the inner wall of the carriage.

[0067] When the adhesive on the inner wall of the carriage cools and solidifies to a semi-solid state, the vehicle is started, moving the carriage away from the support plate 211. At this time, air is injected between the support plate 211 and the inner wall of the carriage through the vent support pipe 213. Because the adhesive fills the anti-detachment groove 212 and completely wraps the support plate 211 and the part of the vent support pipe 213 near the support plate 211, the solidified adhesive on the inner wall of the carriage will not detach from the support plate 211. As the vehicle continues to move away from the support plate 211, the support plate 211 continuously pulls off the adhesive on the inner wall of the carriage. Because air is continuously injected between the adhesive and the inner wall of the carriage through the vent support pipe 213, it can be easily pulled off. During the process of the solidified adhesive being completely torn off, the adhesive adhering to the inner wall of the carriage... The radioactive impurities are adhered to the adhesive, thus achieving the adhesion and cleaning of radioactive solid waste on the inner wall of the carriage. Since the support plate 211 pulls the adhesive from the innermost inner wall of the vehicle outwards, as the adhesive is pulled off, the side of the adhesive attached to the inner wall of the carriage is flipped away from the inner wall to the outside, and the side that is attached to the inner wall of the carriage is gathered inwards. Since the side that is attached to the inner wall of the carriage is the side that adheres to the radioactive waste impurities, the radioactive waste is gathered into the adhesive, thus achieving the adhesion and cleaning of radioactive waste impurities in the carriage and immediately gathering and wrapping the radioactive waste impurities. Furthermore, since the adhesive is used for adhesion and cleaning, there is no situation where the pollution source expands or the pollution source is difficult to gather.

[0068] During equipment use, the horizontal spray tube 233 and the vertical spray tube 231 are heated by the heating element 232, and the adhesive inside is heated by the second feed tube 322 and the first feed tube 321, thereby preventing the adhesive from solidifying and clogging in the horizontal spray tube 233, the vertical spray tube 231, the first feed tube 321 and the second feed tube 322.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
