Description

Technical Field

[0001] At least one embodiment of this application relates to a radioactive material handling apparatus, specifically to a radioactive material packaging and sorting device capable of wrapping, detecting, and classifying radioactive materials. Background Technology

[0002] In production environments with radioactive radiation, waste cotton textiles containing 235U and 238U are often generated. Due to the special nature of radioactive cotton textiles, the disposal process requires storage, transportation, incineration, compression, decontamination, solidification, and packaging.

[0003] Therefore, it is usually necessary to entrust the unified treatment to units with radioactive waste disposal qualifications. However, existing equipment for sorting radioactive materials typically does not package the radioactive materials before sorting them, leading to radioactive contamination of the sorting equipment itself. This radioactive accumulation can endanger the health of users operating the sorting equipment and makes it inconvenient to handle and inspect loose items such as uranium-containing fabrics within the sorting equipment. Furthermore, current technologies generally employ indiscriminate radioactive waste treatment methods, lacking the step of detecting the radioactive content in the waste and classifying it according to the level of radioactive material, thus increasing the volume and cost of radioactive waste disposal.

[0056] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the invention for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0057] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0058] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0059] According to one aspect of the inventive concept of the present invention, a radioactive material packaging and sorting device is provided, comprising: a packaging device including a sealing section configured to contain and seal radioactive material to form a sealed package; and a sorting device including a sorting section configured to receive the sealed package from the packaging device and analyze the content of radioactive material in the sealed package, so as to place multiple sealed packages in different storage boxes according to the level of radioactive material content in the sealed package.

[0060] Figure 1 This is a three-dimensional schematic diagram of the packaging device of the radioactive material packaging and sorting equipment of the present invention; Figure 2 This is a front view of the sorting device of the radioactive material packaging and sorting equipment of the present invention; Figure 3 This is a top view of the sorting device of the radioactive material packaging and sorting equipment of the present invention.

[0061] According to an exemplary embodiment of the present invention, please refer to Figures 1-3 A radioactive material packaging and sorting device is provided, including a packaging device 1 and a sorting device 2. The packaging device 1 includes a sealing section 11. The sealing section 11 is configured to contain and seal radioactive material to form a sealed package. The sorting device 2 includes a sorting section 21. The sorting section 21 is configured to receive sealed packages from the packaging device 1 and analyze the content of radioactive material in the sealed packages, so as to place multiple sealed packages into different storage boxes according to the level of radioactive material content in the sealed packages.

[0062] According to the radioactive material packaging and sorting equipment of the above embodiments of the present invention, it is possible to perform harmless sorting of items worn by workers in radioactive environments, such as clothing, gloves, hats, and other textiles that may be contaminated with radiation. By setting up a packaging device 1 for sealing radioactive materials to form sealed packages, subsequent analysis and sorting of radioactive materials are possible. A sorting device 2 is set up to detect the radioactive material content in the sealed packages and classify the sealed packages according to the level of radioactive material content, facilitating the classified processing of radioactive materials.

[0063] Figure 4 This is a side view of the sorting device of the radioactive material packaging and sorting equipment of the present invention.

[0064] In some exemplary embodiments, reference is made to Figures 2-4The sorting unit 21 includes an analyzer 211, a first storage box 212, and a second storage box 213. The analyzer 211 is configured to analyze the content of radioactive material in sealed packages. The first storage box 212 is located on one side of the analyzer 211 and is used to hold sealed packages with a radioactive material content greater than or equal to a first set value. The second storage box 213 is located on the same side of the analyzer 211 as the first storage box 212 and is used to hold sealed packages with a radioactive material content less than the first set value. For example, the first set value represents the exemption concentration value of radioactive material given in relevant national regulations, such as GB27742-2011 "Standard for Radioactive Nuclide Activity in Materials Exempt from Radiation Protection Supervision". In other words, when the content of radioactive material is less than this exemption concentration value, the radioactive material will not pose a hazard to human health or the environment. In other words, when the content of radioactive material in a sealed package is less than the aforementioned exemption concentration value, it is exempt from radiation supervision, and the sealed package can be treated as ordinary industrial waste. This achieves the effect of differentiated treatment of radioactive waste and reduces processing costs.

[0065] With the above setup, the sealed packages are analyzed by analyzer 211. Based on the level of radioactive material content in the sealed packages, packages with radioactive material content greater than or equal to a first preset value are placed in the first storage box 212, while packages with radioactive material content less than the first preset value are placed in the second storage box 213. This facilitates the classification and processing of sealed packages containing different levels of radioactive material. In this way, the items in the first storage box 212 can undergo further harmless treatment to prevent radioactive pollution of the environment, while the items in the second storage box 213 can be treated as ordinary waste.

[0066] In some exemplary embodiments, reference is made to Figures 2-3 The analyzer 211 includes a base 2111, a housing 2112, a drive assembly 2113, a sample container 2114, and a radiation detector 2115. The housing 2112 is mounted on the base 2111. The drive assembly 2113 is mounted on the base 2111. The sample container 2114 is configured to contain a sealed package and reciprocate linearly under the drive of the drive assembly 2113, causing the sample container 2114 to enter or exit the housing 2112. The radiation detector 2115 extends into the housing 2112 to detect the content of radioactive material in the sealed package placed in the sample container 2114.

[0067] With the above configuration, the sample box 2114 enters or leaves the box 2112 under the drive of the drive component 2113, so as to place a sealed package into the sample box 2114, thereby detecting the content of radioactive material in the sealed package by the radiation detector 2115.

[0068] In some exemplary embodiments, reference is made to Figures 2-3 The analyzer 211 also includes a lead plug 2116. The lead plug 2116 is installed between the sample box 2114 and the drive assembly 2113 and is configured to seal the sample box 2114 when it is moved into the housing 2112 to shield the interior of the housing 2112 from interference from external radioactive materials.

[0069] With the above setup, after the sample box 2114 is moved into the box 2112, the lead plug 2116 seals the sample box 2114 to shield the interference of external radioactive materials on the inside of the box 2112, thereby improving the accuracy of detecting the content of radioactive materials in the sealed package placed in the sample box 2114.

[0070] Figure 5 This is a three-dimensional schematic diagram of the analyzer of the radioactive material packaging and sorting equipment of the present invention; Figure 6 This is a front view of the analyzer in the radioactive material packaging and sorting equipment of the present invention; Figure 7 This is a top view of the analyzer in the radioactive material packaging and sorting equipment of the present invention.

[0071] In some exemplary embodiments, reference is made to Figures 5-7 The drive assembly 2113 includes a slide rail 21131, a mounting bracket 21132, a motor 21133, and a push rod 21134. The slide rail 21131 is mounted on a base 2111 on one side of the housing 2112. The mounting bracket 21132 is slidably mounted on the slide rail 21131. Lead plugs 2116 and sample boxes 2114 are mounted on the mounting bracket 21132 to move with it. The motor 21133 is mounted on the base 2111. The push rod 21134 is connected at both ends to the motor 21133 and the mounting bracket 21132 respectively, so that, driven by the motor 21133, it pushes the mounting bracket 21132 to reciprocate linearly along the slide rail 21131.

[0072] It should be noted that in this embodiment, the mounting support 21132 is constructed in an L-shape. One end of the mounting support 21132 is slidably mounted on the slide rail 21131, and the other end is equipped with a lead plug 2116 and a sample box 2114.

[0073] In some exemplary embodiments, reference is made to Figure 5 The motor 21133 and the slide rail 21131 are respectively installed on opposite sides of the housing 2112, and the push rod 21134 is installed at the bottom of the housing 2112.

[0074] In some exemplary embodiments, reference is made to Figures 2-3The analyzer 211 also includes a camera 2117 and a robotic arm 2118. The camera 2117 is configured to identify the location of the sealed package. The robotic arm 2118 is configured to place the identified sealed package into the sample box 2114 and, based on the content of radioactive material in the sealed package detected by the radiation detector 2115, place the sealed package into either the first storage box 212 or the second storage box 213.

[0075] A camera 2117 is mounted above the first conveyor belt 232 to identify the position of the sealed package on the first conveyor belt 232. A robotic arm 2118 is mounted on the side of the second support frame 231 away from the screening section 22 to grasp the sealed package placed on the first conveyor belt 232.

[0076] In some exemplary embodiments, reference is made to Figures 2-3 The analyzer 211 also includes a weighing device 2119. The weighing device 2119 is configured to weigh the mass of the sealed package. A radiation detector 2115 is used to calculate the ratio of the radioactive material content in the sealed package to the mass of the sealed package, thus obtaining the emissivity. A robotic arm 2118 is configured to place the sealed package into a first storage box 212 when the emissivity is greater than or equal to a second set value, and to place the sealed package into a second storage box 213 when the emissivity is less than the second set value. For example, the second set value indicates that, according to GB27742-2011 "Standards for Radioactive Nuclide Activity in Materials Exempt from Radiation Protection Supervision," when the specific activity of the radionuclide in the sealed package is ≤1 Bq / g, it is exempt from radiation protection supervision. That is, when the ratio of the radioactive material content in the sealed package to the mass of the sealed package is ≤1 Bq / g, the radioactive material in the sealed package will not cause harm to humans or the environment, and the sealed package can be treated as ordinary industrial waste. This achieves the goal of differentiated treatment of radioactive waste and reduces operating costs.

[0077] In this embodiment, the analyzer 211 operates as follows: The robotic arm 2118 grasps the sealed package identified by the camera 2117 and places it on the weighing device 2119 for weighing. The motor 21133 drives the mounting bracket 21132 to move along the slide rail 21131 via the push rod 21134, causing the sample box 2114 to leave the housing 2112. The robotic arm 2118 places the weighed sealed package into the sample box 2114. The motor 21133 again drives the mounting bracket 21132 to move along the slide rail 21131 via the push rod 21134, causing the sample box 2114 to enter the housing 2112. The radiation detector 2115 detects the content of radioactive material in the sealed package placed in the sample box 2114 and calculates the ratio of the radioactive material content to the mass of the sealed package to determine whether the radioactive material content in the sealed package exceeds the standard.

[0078] It should be noted that in this embodiment, the robotic arm 2118 can grasp the sealed package placed on the first conveyor belt 232 and place the sealed package on the weighing device 2119, further place the weighed sealed package into the sample box 2114, and place the sealed package that has been detected by the analyzer 211 into the first storage box 212 or the second storage box 213 according to the level of radioactive material content in the sealed package.

[0079] In some exemplary embodiments, the radiation detector 2115 includes a sodium iodide detector or a gamma ray detector.

[0080] It should be noted that, in this embodiment, the radiation detector 2115, such as a sodium iodide detector, works on the following principle for detecting radioactive materials: When the gamma rays generated by the decay of radioactive materials pass through the scintillator (sodium iodide), the scintillator is ionized and excited by the gamma rays, emitting light of a certain wavelength. That is, the greater the amount of radioactive isotope, the more flashes are caused on the scintillator, and the more electrical pulses are recorded by the sodium iodide detector.

[0081] Radioactive waste (such as nuclides 235U and 238U) emits gamma rays with different energy characteristics upon decay. For a sealed package, the gamma rays emitted are recorded in energy order to obtain the gamma-ray spectrum of the radioactive material within the package. By dividing the number of pulses at a specific energy level in the gamma-ray spectrum by the probability of that gamma ray generation, the decay number of the radioactive waste (e.g., nuclides 235U and 238U) at the current time can be obtained. A sodium iodide detector records and calculates the number of pulses in the energy spectrum to obtain the corresponding specific activity.

[0082] When the specific activity of radioactive materials in a sealed package is ≤1 Bq / g, it can be treated as ordinary industrial waste, so as to achieve differentiated treatment of radioactive waste and reduce treatment costs.

[0083] In some exemplary embodiments, reference is made to Figure 1 The encapsulation unit 11 includes a feed cylinder 111, a film feeding assembly 112, and a bag maker 113. The feed cylinder 111 extends vertically, and its two ends are respectively provided with a feed end 1111 and a discharge end 1112. The film feeding assembly 112 is configured to cover the outside of the feed cylinder 111 with a plastic film. The bag maker 113 is fitted over the outside of the feed cylinder 111 and is configured to seal the lower end of the plastic film covering the outside of the feed cylinder 111, seal the plastic film along the circumferentially extending side edge of the feed cylinder 111, and seal and melt the upper end of the plastic film after the radioactive material is transferred into the plastic film to seal the radioactive material.

[0084] With the above configuration, the bag maker 113 seals the lower end of the plastic film wrapped around the outside of the feed cylinder 111. Radioactive material enters the feed cylinder 111 through the feed end 1111 and flows out of the feed cylinder 111 from the discharge end 1112, entering the inside of the plastic film wrapped around the feed cylinder 111. As the plastic film wrapped around the outside of the feed cylinder 111 extends downward, the belt maker 113 seals the plastic film along the circumferentially extending side edge of the feed cylinder 111. After the radioactive material is completely transferred into the inside of the plastic film, the belt maker 113 seals and melts the upper end of the plastic film, thus sealing the radioactive material inside the plastic film.

[0085] It should be noted that in this embodiment, the feed end 1111 of the feed cylinder 111 is about 1 meter above the ground, which makes it convenient for the user to put radioactive materials into the feed cylinder 111.

[0086] In addition, a rectangular tray can be provided above the feed cylinder 111. The bottom of the rectangular tray is provided with a through hole that communicates with the feed end 1111 of the feed cylinder 111. Push plates extending vertically are provided on all four sides of the rectangular tray. Each push plate is provided with a drive motor for driving the push plate to move horizontally, so as to squeeze the radioactive material placed on the rectangular tray, so that the radioactive material passes through the through hole and enters the feed cylinder 111 through the feed end 1111.

[0087] In some exemplary embodiments, reference is made to Figure 1 The film feeding assembly 112 includes a placement frame 1121, a roller 1122, an adjusting rod 1123, and a kneading gear 1124 arranged sequentially from top to bottom in the vertical direction. The plastic film is rolled on the placement frame 1121 and passes through the roller 1122 and the adjusting rod 1123 and extends downward. The side edge of the plastic film extending circumferentially along the feed cylinder 111 is squeezed by the kneading gear 1124 to wrap around the feed cylinder 111.

[0088] It should be noted that, in this embodiment, the rolled plastic film can be manually installed on the placement rack 1121, the plastic film is passed through the roller 1122 and the adjusting rod 1123 and extends downward, and the plastic film is wrapped around the feed cylinder 111. The plastic film is then pressed onto the kneading gear 1124 along the circumferentially extending side edge of the feed cylinder 111, so that as the plastic film extends downward, the plastic film on the placement rack 1121 can be sequentially wrapped around the feed cylinder 111.

[0089] In some exemplary embodiments, reference is made to Figure 1The bag maker 113 includes a support frame 1131, a first sealer 1132, and a second sealer 1133. The support frame 1131 is fitted over the feed cylinder 111. The first sealer 1132 is located on the side of the support frame 1131 near the kneading gear 1124 to seal the two facing side edges of the plastic film extending circumferentially along the feed cylinder 111. The second sealer 1133 is located on the underside of the support frame 1131 and sequentially seals the lower and upper ends of the plastic film extending to the underside of the bag maker 113, thereby forming a sealed package.

[0090] In this embodiment, the first sealer 1132 seals the two facing side edges of the plastic film extending circumferentially along the feed cylinder 111, and the second sealer 1133 sequentially seals the lower and upper ends of the plastic film extending to the lower side of the bag maker 113, so as to seal the radioactive material inside the plastic film.

[0091] In some exemplary embodiments, reference is made to Figure 1 The bag maker 113 also includes a heat-melt cutter 1134, positioned above the second sealer 1133, to cut the sealed package from the plastic film by heat melting.

[0092] In some exemplary embodiments, reference is made to Figures 2-3 The sorting device 2 also includes a screening section 22 and a first conveying section 23. The screening section 22 is configured to receive multiple sealed packages and output them sequentially by vibration. The first conveying section 23 is located below the discharge port 226 of the screening section 22 to convey the sealed packages received from the discharge port 226 toward the analyzer 211.

[0093] With the above setup, the screening unit 22 outputs the received multiple sealed packages one by one by vibration, so that the analyzer 211 can detect the sealed packages.

[0094] In some exemplary embodiments, reference is made to Figures 2-3 The screening section 22 includes a first support frame 221, a support base 222, a vibration motor 223, a vibrating plate 224, and a feeding bin 225.
