Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of radioactive waste treatment, and particularly to a press device for radioactive filter elements, an automated compression system and a treatment method thereof. Background Art
[0002] During nuclear activities, a large amount of radioactive aerosol is generated in the radioactive plant, which causes harm to the environment and the operators in the plant. It is necessary to configure a ventilation system and a filtration system as required to purify and collect the radioactive aerosol. To ensure the collection efficiency of the aerosol, the filter element needs to be replaced regularly. Since the filter element is radioactive and belongs to radioactive waste, and the sizes and shapes of the replaced filter elements are different, if they are directly loaded into the necked waste bin, it will cause waste of the space in the waste bin, which does not meet the volume reduction requirements for radioactive waste treatment. In order to reduce the volume of the filter element and improve the utilization rate of the volume of the necked waste bin, various different filter elements need to be compressed into similar shapes. At the same time, since a large amount of radioactive aerosol will be generated during the compression and volume reduction process, it is necessary to isolate the whole compression process from the outside world. At the same time, in order to reduce the contact of the operator with radioactivity, the whole compression process needs to be remotely controlled. Summary of the Invention

[0107] In this embodiment, the first operating glove is used to remove the cover bolts of the steel box 6, the rotating platform 11 is used to facilitate the rotation of the steel box 6 when removing the bolts on the steel box 6, and the designs of the first electric door 51 and the second electric door 52 make the first feeding transition chamber 1 completely sealed during the process of taking out the filter element, preventing the leakage of radioactive gas; the cover suction device includes: a hoisting mechanism 151 and a telescopic sleeve 152 fixed on the top of the first feeding transition chamber 1, and an electromagnetic chuck 153 fixedly connected to the steel wire rope in the hoisting mechanism 151, the electromagnetic chuck 153 is used to suck the cover on the steel box 6; the three-axis truss manipulator includes: a bracket 131, a lateral translation mechanism 133, a longitudinal translation mechanism, a lifting mechanism 134 and a jaw mechanism 135; wherein, the bracket 131 is fixed on one side of the rotating platform 11, a translation track of the lateral translation mechanism 133 is arranged on the top cross beam 132 of the bracket 131, and one end of the translation track is located directly above the second filter element conveying roller track 14, the lateral translation mechanism 133 is assembled on the translation track on the top cross beam 132, and the longitudinal translation mechanism, the visual recognition system, the lifting mechanism 134 and the jaw mechanism 135 are all assembled on the lateral translation mechanism 133.
[0108] In this example, after the first electric door 51 is opened, the steel box 6 is placed on the vibrating roller table 12, and then the first electric door 51 is closed. Then, the cover bolts of the steel box 6 are removed through the first operating glove and the rotating platform 11. After the cover bolts are removed, the electromagnetic chuck 153 is lowered to the top of the cover of the steel box 6 by the hoisting mechanism 151 and the telescopic sleeve 152.

At this time, the third electric door 53 is closed, the third folding conveying roller path 493 is opened, and at the same time, the lifting platform 47 on the press device 4 rises. After the lifting platform 47 rises, it is connected to the unfolded third folding conveying roller path 493. Subsequently, the push rod device 49 pushes the radioactive filter element with an intact outer packaging bag moving on the third folding conveying roller path 493 onto the lifting platform 47. Then, the lifting platform 47 descends to the initial position, the third folding conveying roller path 493 folds back, and the push rod device 49 returns to the initial position. At this time, the compression chamber end cover 452 descends under the push of the at least one third hydraulic rod 451, and the top pressing mechanism 442 descends simultaneously under the push of the second hydraulic rod 441. The compression chamber end cover 452 and the top pressing mechanism 442 descend onto the opening of the compression chamber, seal the opening of the compression chamber and form a sealed chamber. Subsequently, the local exhaust system 401 is started, and the puncturing device 443 in the top pressing mechanism 442 punctures the outer packaging of the radioactive filter element. At the same time, the air extraction device 40 extracts the gas in the sealed chamber and discharges it into the local exhaust system 401. After the air extraction device 40 completes air extraction, the plurality of side pressing mechanisms 48 simultaneously push all the moving side walls 46 to side-press the side walls of the radioactive filter element, and maintain the pressure after side-pressing to a predetermined size. Then, the top pressing mechanism 442 top-presses the top of the radioactive filter element and maintains the pressure after top-pressing to a predetermined height. After maintaining the pressure for a certain period of time, the top pressing mechanism 442 and the moving side walls 46 simultaneously return to the initial position. At this time, the lifting platform 47 rises again, and at the same time, the fourth folding conveying roller path 494 unfolds. After the fourth folding conveying roller path 494 unfolds, it is connected to the rising lifting platform 47. Then, the push rod device 49 on the third filter element conveying roller path 491 pushes the compressed radioactive filter element on the lifting platform 47 onto the fourth folding conveying roller path 494. The fourth folding conveying roller path 494 conveys the compressed radioactive filter element to the fourth filter element conveying roller path 492. At this time, the fourth electric door 54 is opened, and at the same time, the fifth folding conveying roller path 495 at the second end of the fourth filter element conveying roller path 492 unfolds. Then, the compressed radioactive filter element is conveyed out of the compression working chamber 3 through the fifth folding conveying roller path 495. Subsequently, the fifth folding conveying roller path 495 refolds, and the fourth electric door 54 is closed.
