Technical Field

[0001] The utility model relates to the technical field of waste bin transfer, in particular to a discharging and transferring device for radioactive waste storage bins. Background Art

[0002] Radioactive waste contains radioactive nuclides or is contaminated by radioactive nuclides, with a concentration or activity greater than the clearance level specified by the national regulatory department, and is expected not to be reused. When entering an environment with radioactivity, workers must wear labor protection supplies for protection. After use, labor protection supplies and the like become radioactive waste. The hazards of radioactive waste include physical toxicity, chemical toxicity, and biological toxicity. Therefore, the treatment of radioactive waste is extremely important. If not properly treated, it may cause serious harm. Currently, when treating some radioactive waste, pyrolysis gasification is usually used for harmless treatment, and the treated substances are packaged and sealed, and then landfilled after transportation. To ensure the safety of workers, the substances after pyrolysis gasification are usually loaded into storage bins through a treatment tank and then transported. After the storage bin is filled with the pyrolyzed and gasified substances, it is very heavy. Currently, it is necessary to manually lift it onto the transport vehicle for transportation, and the whole process is labor-consuming. Therefore, it is necessary to develop a discharging and transferring device for radioactive waste storage bins that can automatically transfer the storage bin from the treatment tank and save manpower. Summary of the Utility Model

[0003] Aiming at the above technical problems, the utility model provides a discharging and transferring device for radioactive waste storage bins that can automatically transfer the storage bin from the treatment tank and save manpower, so as to solve the problem of high manual labor intensity caused by manually lifting the storage bin during the transfer of the storage bin.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the utility model with reference to the accompanying drawings.

[0017] As Figure 1 、2 A discharging and transferring device for radioactive waste storage barrels as shown in the figure, including a treatment box 1. A pyrolysis gasification device is arranged on the upper part of the treatment box 1, and the pyrolysis gasification device is used to treat radioactive waste. The feeding pipe 2 of the pyrolysis gasification device penetrates through the top of the treatment box 1 and extends into its interior, and a valve for controlling the discharge is arranged on the feeding pipe 2. One side of the treatment box 1 is connected with a sealing door 5, and a roller conveyor 6 is arranged through the sealing door 5. The roller conveyor 6 is driven by a motor. On both sides of the sealing door 5 outside the treatment box 1, first telescopic cylinders 9 perpendicular to the surface of the treatment box 1 are fixedly connected. The inner side of the output end of the first telescopic cylinder 9 is fixedly connected with a second telescopic cylinder 10 with an upward output end through a connecting plate and bolts. The output end of the second telescopic cylinder 10 is fixedly connected with a clamping plate 11. A transparent viewing window 3 is arranged at the front end of the treatment box 1, and a protective glove 4 is connected to the transparent viewing window 3. It should be noted that in this embodiment, in order to facilitate the stable lifting of the radioactive waste storage barrel, the inner side of the clamping plate 11 is in an arc-shaped structure conforming to the outer surface of the radioactive waste storage barrel. The top end of the radioactive waste storage barrel has an annular boss, and the clamping plate 11 will contact the lower surface of the annular boss during the rising process, so as to be able to lift the radioactive waste storage barrel.

[0018] In order to ensure the running stability of the first telescopic cylinder 9 and avoid damage to it caused by the overweight of the radioactive waste storage barrel, mounting frames 7 are fixedly connected to the upper parts on both sides of the roller conveyor 6 outside the treatment box 1. The bottom of the middle position of the output shaft of the first telescopic cylinder 9 is fixedly connected with a vertically downward support rod 12, and the bottom of the support rod 12 is rotatably connected with a support wheel 13. The support wheel 13 is rollingly arranged on the mounting frame 7. In order to facilitate the installation of the roller conveyor 6, a bracket 8 is fixedly connected to the bottom of the roller conveyor 6. It should be noted that in this embodiment, the first telescopic cylinder 9 is connected to the lower part of the treatment box 1. During the process of lifting the radioactive waste storage barrel, the second telescopic cylinder 10 needs to extend more, so as to facilitate the contact between the bottom end of the radioactive waste storage barrel and the transfer trolley when it descends.

[0019] In order to further improve the structural stability, a roller groove 14 is opened on the mounting frame 7, and the support wheel 13 is rollingly arranged in the roller groove 14. In order to be able to transfer the radioactive waste storage barrel to the transfer vehicle outside the roller conveyor 6 by using the first telescopic cylinder 9, the support rod 12 is fixedly connected to the middle part of the output end of the first telescopic cylinder 9, and the roller groove 14 is opened to the edge position of one end of the mounting frame 7. When the support wheel 13 rolls to the end of the roller groove 14 along with the elongation of the first telescopic cylinder 9, the radioactive waste storage barrel has completely left the roller conveyor 6. When the second telescopic cylinder 10 descends, the radioactive waste storage barrel can be stably placed on the transfer trolley.

[0020] In order to facilitate the opening and closing control of the sealing door 5, clamping rails 17 are fixedly connected to the outside of the processing box 1 on both sides of the sealing door 5. Both sides of the sealing door 5 are slidably clamped in the clamping rails 17. Third telescopic cylinders 15 are fixedly connected to both sides of the clamping rails 17. Lifting plates 16 are fixedly connected to both sides of the top of the sealing door 5. The output ends of the third telescopic cylinders 15 are fixedly connected to the bottoms of the lifting plates 16.

[0021] It should be noted that the first telescopic cylinder 9, the second telescopic cylinder 10, and the third telescopic cylinder 15 can all be any one of a hydraulic cylinder, an electric cylinder, and a pneumatic cylinder. When a hydraulic cylinder is used, a corresponding pressure supply mechanism needs to be used in a supporting manner. When a pneumatic cylinder is used, a corresponding air pump needs to be used in a supporting manner. In order to ensure the operation stability, in this embodiment, the first telescopic cylinder 9 and the second telescopic cylinder 10 are hydraulic cylinders, and the third telescopic cylinder 15 is an electric cylinder.

[0022] The working process of this embodiment is as follows:

[0023] When radioactive waste is being processed, control the third telescopic cylinder 15 to extend, open the sealing door 5, place the radioactive waste storage barrel on the roller conveyor 6, control its reverse rotation to transport the radioactive waste storage barrel into the processing box 1, control the third telescopic cylinder 15 to retract to close the sealing door 5, after the radioactive waste is processed by the cracking and gasification device, discharge it from the blanking pipe 2. Open the valve on the blanking pipe 2, control the cracked gasified product to enter the storage barrel, close the valve, and then seal the packaging bag in the storage barrel through the protective glove 4. Control the sealing door 5 to open, control the roller conveyor 6 to run forward, transport the storage barrel to the outside of the processing box 1, cover the sealing cover of the storage barrel, then control the first telescopic cylinder 9 to operate so that the clamping plate 11 corresponds to the upper and lower positions of the storage barrel, then control the second telescopic cylinder 10 to extend to lift the storage barrel, control the first telescopic cylinder 9 to extend until the storage barrel is transferred above the pre-placed transfer vehicle, then control the second telescopic cylinder 10 to retract to place the storage barrel on the transfer trolley. During the extension process of the first telescopic cylinder 9, the supporting wheel 13 rolls in the roller groove 14, and the supporting rod 12 plays a supporting role for the first telescopic cylinder 9.
