Abstract

The invention discloses a device and method for disassembling a low-radioactivity gather type waste filter. The low-radioactivity gather type waste filter to be disassembled is placed into a disassembling system, after an outer package is removed, a bottom seam cutting machine, a top seam cutting machine, a vertical seam cutting machine and a transfer tray are cooperated for carrying out bottom seam cutting on the front handle end face, top seam cutting on the air exhaust top face, vertical seam cutting on the front handle face and vertical seam cutting on the rear handle face of a metal shellof the low-radioactivity gather type waste filter, the front handle face and the rear handle face are separated in first batch, a core is recycled after cut, and the metal shell and glue attached tothe metal shell are heated in a tunnel type drying oven and subjected to glue shoveling treatment through a glue shoveling negative pressure ventilation cabinet to be classified and recycled. The gather type waste filter can be disassembled before waste treatment, meal materials and nonmetal materials are classified, and the device and method have the advantages of being high in automation degree,high in efficiency, safe and environmentally friendly, saving energy and the like.

Description

technical field [0001] The invention relates to a device and method for dismantling low-radioactivity pleated waste filters decommissioned in nuclear air and gas treatment systems, more specifically for specific activity less than or equal to 4×10 6 Bq / kg (GB9133-1995, Class I radioactive solid waste) equipment and method for dismantling and dismantling and material classification of dense pleated waste filters before waste treatment. Background technique [0002] In accordance with the country's long-term plan to develop clean nuclear energy and expand the nuclear industry, with the rapid development of nuclear power technology, filters used in nuclear facilities, especially low-radioactive waste filters, are being decommissioned and piled up in large quantities. For the low-radioactive dense pleated waste filter, the domestic nuclear industry unit simply dismantles the radioactive waste filter manually, puts it into a 200L standard waste barrel for storage, and then compre...
