Embodiment 1

[0059] This embodiment discloses a radioactive metal preparation device, such as figure 1As shown, it includes crushing unit, transport unit and capping unit, all of which are set in preparation area B. Wherein, the crushing unit includes a crusher 3, which is set at the crushing station in the preparation area B, and is used for crushing and compressing radioactive metals.

[0060] In this embodiment, the crusher 3 can usually crush the radioactive metal into fragments with a size of 10-50 mm. In addition, the crusher 3 also has a compression effect on the pipes, profiles, etc. in the radioactive metal. In this embodiment, the crushing The machine 3 adopts a double-shaft crusher, and its compression ratio to the pipeline can reach more than 90%, which can greatly reduce the volume of radioactive metals and improve the utilization rate of the inner space of the charging barrel 4. Of course, the crusher 3 can also use an impact crusher, a gyratory crusher or other crushers cap...

Embodiment 2

[0097] This embodiment discloses a radioactive metal processing system, including a feeding device, and also includes the radioactive metal preparation device in Embodiment 1, wherein the feeding device includes a vibrator 1 and a conveyor belt, and the feeding device includes a vibrator 1 and a conveyor belt 2, and the vibrator 1 is set in the receiving area A, and is used for uniform feeding of the received radioactive metal.

[0098] The conveyor belt 2 is arranged between the discharge port of the vibrator 1 and the feed port of the crusher 3, and is used for conveying the discharged radioactive metal.

[0099] In this embodiment, the radioactive metal processing system further includes a crane and a storage container, wherein the storage container is set in the temporary storage area C, and is used to store the charging barrel 4 after packaging the debris.

[0100] Among them, receiving area A and temporary storage area C are adjacent to preparation area B respectively. ...

Embodiment 3

[0107] This embodiment discloses a radioactive metal treatment method, which can be used in the radioactive metal treatment system of Example 2, and the method includes the following steps:

[0108] Carry out blanking of radioactive metals, and transport the unloaded material to the crusher 3 on the crushing station for crushing, and place the empty charging barrel 4 on the barrel feeding station f of the barrel feeding area D, and then Transport it to the barrel loading station in the preparation area B, and then put the broken material obtained after being crushed by the crusher 3 into the barrel 4 .

[0109] Specifically, as shown in process 03, the radioactive metal is grasped, transported or dumped into the vibrator 1 in the receiving area A, and the radioactive metal is transferred from the vibrator 1 to the conveyor belt 2 .

[0110] As shown in process 04, the radioactive metals are transported to the staging area B via the conveyor belt 2.

[0111] As shown in proces...

Abstract

The invention discloses a radioactive metal reconditioning device, which comprises a crushing unit, a conveying unit and a cover taking and sealing unit, wherein the crushing unit comprises a crusher, the crusher is arranged at a crushing station of a reconditioning area and used for crushing and compressing radioactive metal, the conveying unit is used for conveying a loading barrel from the inlet of the reconditioningarea to a loading barrel station below the material outlet of the crusher, and the cover taking and sealing unit is arranged at a cover taking and sealing station between the inlet of the reconditioning area and the crusher, and is used for opening the cover of the loading barrel before loading of the loading barrel and sealing the cover of the loading barrel after loading of the loading barrel. The invention further discloses a radioactive metal treatment system and method comprising the radioactive metal reconditioning device. According to the radioactive metal reconditioning device, radioactive metal can be rapidly crushed and compressed to a set size, so that the reconditioning requirements of metal wastes such as pipelines, plates, profiles and the like generated during operation and decommissioning of nuclear facilities are met.

Description

technical field [0001] The present invention specifically relates to a radioactive metal conditioning device, a radioactive metal processing system comprising the radioactive metal conditioning device, and a radioactive metal processing method. Background technique [0002] In nuclear industry production, radioactive metals are loaded into charging barrels. Due to their different sizes and lengths and disorderly stacking, the volume reduction effect of radioactive metals is poor and the maintenance efficiency is low. [0003] In the prior art, tools such as pressure shears are usually used to simply cut the radioactive metal and then pack it into barrels. Although the size and length of the radioactive metal are reduced, [0004] However, it still cannot meet the size and length requirements of the barrel loading process, the space utilization rate of the barrel is low, and the shearing efficiency of the pressure shear is low and takes a long time. Contents of the inventio...
