Description

Technical Field

[0001] This invention relates to the field of radioactive pipe cutting technology, and more particularly to a radioactive pipe cutting device with a heated chamber. Background Technology

[0002] The development of reactor technology has placed higher demands on the performance of materials. Whether in existing commercial reactors or in developing fourth-generation reactors, fusion reactors, and traveling wave reactors, materials must undergo preliminary irradiation testing within the research reactor for safety reasons before entering service. Due to considerations of the material's inherent properties, service environment, and service temperature, some materials must be sealed in cylindrical irradiation boxes during irradiation within the research reactor. After irradiation testing, the radioactive sample boxes need to be cut open in a hot chamber to remove the samples for subsequent analysis and testing. Meanwhile, tubular materials are one of the key material forms within reactors, such as nuclear fuel cladding tubes. Therefore, there is a strong need for cutting irradiated radioactive tubing within a hot chamber.

[0003] Currently, commonly used cutting devices for radioactive tubes in hot chambers include: 1. abrasive wheel cutters; 2. tube cutters; and 3. laser cutters. Abrasive wheel cutters use diamond abrasive wheel blades to cut the sample. The lower end of the blade has a groove for holding coolant. The sample is clamped on the sample stage, and during the cutting process, it is gradually cut off under gravity. Abrasive wheel cutters use water or coolant to cool the abrasive wheel blades. This method generates a large amount of radioactive waste liquid and chips, which are difficult to collect effectively, causing contamination of the hot chamber, affecting subsequent equipment maintenance, and incurring high disposal costs. Tube cutters have two or more cutting blades arranged around the sample, rotating relative to it and gradually squeezing inwards to eventually cut the sample. Tube cutters are suitable for a smaller range of sample sizes, have a relatively slow cutting speed, and are prone to introducing deformation and burrs during the cutting process. They are not suitable for samples tightly assembled with the irradiation box, as this can cause the sample to become stuck and difficult to remove. Laser cutting machines have a laser emitter and corresponding cooling and control system set up outside the hot chamber. The laser passes through a through-wall laser tube through the hot chamber wall to reach the laser cutting head located inside the hot chamber to cut the sample. Laser cutting machines have the characteristics of wide cutting range, fast cutting speed and high precision, but they also have disadvantages such as difficulty in cutting through, easy to produce sharp corner ablation, and temperature rise during the cutting process affecting the performance of the sample after irradiation.

[0004] In existing technologies, abrasive wheel cutters use water or coolant to cool the cutting disc. This method generates a large amount of radioactive waste liquid and chips, which are difficult to collect effectively, contaminate the hot chamber, affect subsequent equipment maintenance, and incur high disposal costs. Tube cutters are suitable for a limited range of sample sizes, have relatively slow cutting speeds, and are prone to introducing deformation and burrs during cutting. They are unsuitable for samples tightly assembled with the irradiation chamber, as this can cause the sample to become stuck and difficult to remove. Laser cutters offer advantages such as a wide cutting range, high cutting speed, and high precision, but also have drawbacks such as difficulty in cutting through completely, the tendency to produce sharp-angle ablation, and the temperature rise during cutting affecting the post-irradiation performance of the sample.

When the vacuuming component 153 is in operation, a robotic arm grips the vacuum handle 1533, aligns the vacuum port 1532 with the area to be cleaned, and the vacuum pipe 1531 draws air inward to collect fine debris and dust.

While shielding against radioactive rays, it facilitates visual inspection of the cutting process and can reduce radiation damage to other electronic components in the hot chamber caused by the workpiece's radioactivity.

[0059] like Figure 6 As shown, Figure 6 This is a schematic diagram of the shielding component structure provided in an embodiment of the present invention. Specifically, the shielding component 16 mainly consists of a protective cover b 161, a mechanical gripper 162, a sliding door 163, a viewing window 164, a sliding door guide rail 165, and a cable outlet (connecting cable tray) 166. The protective cover b 161 surrounds the main body 1 of the device, preventing radioactive debris and dust from splashing. The mechanical gripper 162 is held by the mechanical arm, causing the sliding door 163 to move along the sliding door guide rail, thus opening and closing the sliding door 163. During the cutting process, the sliding door 163 is closed, and the cutting progress can be observed through the viewing window 164. The viewing window 164 is made of lead glass, which can reduce the radiation damage of the workpiece's radioactivity to the electronic components of other equipment in the hot chamber.

[0060] Optionally, the portion of the cable tray 2 inside the hot chamber is a square stainless steel frame covered with lead sheet, and the portion passing through the interior of the hot chamber wall is a tubular stainless steel. The tubular stainless steel matches the size of the through-hole on the hot chamber wall, and power lines, control lines, and gas pipelines are laid inside the cable tray 2.

[0061] In this embodiment of the invention, the cable tray 2 is used to connect the main body 1 of the device and the electrical control cabinet 3. The part of the cable tray 2 inside the hot chamber is a square stainless steel frame, the outside of which is covered with lead sheet. The part that passes through the inside of the hot chamber wall is a tubular stainless steel, the size of which matches the through hole on the hot chamber wall. Power lines, control lines and gas pipelines are laid inside the cable tray 2.

[0062] In this embodiment of the invention, a pneumatic chuck is used to clamp the workpiece, applicable to a wide range of sample sizes, and sample loading and unloading are simple. Compared to cutting methods such as grinding wheels and pipe cutters, in this invention, the workpiece clamping assembly is fixed on the base and includes a clamping rotating component, a metal chain, and a rotary motor. The rotary motor drives the clamping rotating component to rotate via the metal chain, resulting in high cutting speed. In cutting methods such as grinding wheels and pipe cutters, the blade is mechanically clamped, making blade replacement relatively cumbersome. Improper operation can easily loosen the blade, leading to blade damage during cutting. This invention uses a pneumatic clamping method, facilitating blade replacement. The blade is beveled and equipped with a cutting guard, effectively collecting cutting debris. Other cutting methods often use water rinsing to collect debris and dust, generating significant amounts of waste liquid. The debris collection assembly of this invention includes a collection box and a dust suction component, capable of collecting both large and small debris and dust, achieving a high debris collection rate. The shielding component of the present invention includes a protective cover, a viewing window, etc., wherein the viewing window is made of lead glass, which has good radiation resistance and facilitates visual inspection of the cutting status.

[0063] In this embodiment of the invention, the radioactive tube is cut in a hot chamber, which has the advantages of convenient tool replacement, wide range of applicable sample sizes, simple sample loading and unloading, fast cutting speed, high debris collection rate, and good radiation resistance.

[0064] In this embodiment of the invention, the main body of the device includes a base and a shielding assembly. The shielding assembly is arranged around the main body of the device, forming a shielding space with the base. The shielding space includes a tool clamping assembly, a workpiece clamping assembly, a tool feed assembly, and a chip collection assembly disposed on the base. The tool feed assembly is connected to the tool clamping assembly and is disposed at the clamping end of the workpiece clamping assembly. The air compressor is pneumatically connected to the tool clamping assembly, the workpiece clamping assembly, and the chip collection assembly. This invention uses a pneumatic chuck to clamp the workpiece, and is applicable to a wide range of sample sizes. Sample loading and unloading are simple; the workpiece clamping assembly is fixed on the base, including a clamping rotating part, a metal chain, and a rotary motor. The rotary motor drives the clamping rotating part to rotate through the metal chain, resulting in fast cutting speed; the tool is clamped pneumatically, making tool replacement convenient. The tool is beveled and equipped with a cutting guard, which can effectively collect cutting debris; the debris collection assembly includes a collection box and a dust collection part, which can collect both large debris and small debris and dust, resulting in a high debris collection rate; the shielding assembly includes a protective cover and a viewing window, among which the viewing window is made of lead glass, which has good radiation resistance and allows for easy visual inspection of the cutting status.
