Description

Technical Field

[0001] The present invention relates to the field of radioactive drug production, and in particular to a radioactive solid waste treatment system and method. Background Art

[0002] In the production process of radiopharmaceuticals, a large amount of radioactive solid waste is inevitably generated. These wastes are highly radioactive and can cause serious radiation damage to people around them. In order to deal with these radioactive solid wastes, the commonly used method is to transfer these wastes from the production equipment into special closed shielding containers. These shielding containers can effectively block the radiation of radioactive substances and protect the safety of personnel.

[0003] The transfer is usually done manually, and the solid waste will be left to rest for a period of time. During this period, the radioactive solid waste will experience its own half-life, which is a natural physical process through which the radioactivity of the radioactive material will gradually weaken and eventually turn into ordinary solid waste. When the solid waste has passed its half-life and the radioactivity has dropped to a safe level, the staff will intervene again to remove the waste from the shielding container. At this point, the waste is no longer radioactive and can be handled in the same way as ordinary solid waste.

[0004] However, in actual operation, this method has some problems. First, the treatment of radioactive solid waste requires a large number of shielded containers to store waste waiting for its half-life. These containers not only take up a lot of space, but also cannot be reused during the waiting period, resulting in a waste of resources. Secondly, in the transfer process of solid waste, a lot of human resources are required. The staff not only have to carry out heavy handling work, but also have to pay attention to safety at all times during the operation to prevent accidental radiation exposure. In addition, due to the particularity of radioactive solid waste, the staff will inevitably face certain radiation risks during the operation.

[0005] Therefore, how to improve existing treatment methods, reduce radiation risks to personnel, and improve treatment efficiency is an urgent problem to be solved in the field of radioactive waste management. Summary of the invention

DETAILED DESCRIPTION

[0045] A radioactive solid waste treatment system and method of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0048] In a first aspect, the present invention provides a radioactive solid waste treatment system, please refer to Figure 1 , Figure 2 and Figure 3 ,include:

[0049] Processing device 1;

[0050] A waste shielding device 3 is placed in the processing device 1 and fixedly connected to the bottom surface of the processing device 1, and a waste bag is arranged in the waste shielding device 3;

[0051] A plurality of decay boxes 2 are sequentially arranged inside the processing device 1 and fixedly connected to the bottom of the processing device 1. A sensor is fixedly connected to the side wall of the decay box 2 near the cover of the decay box 2. The sensor is used to detect parameter information in the decay box 2.

[0052] A navigation track 4 is fixedly disposed on the bottom surface of the processing device 1 and has a first distance from a side surface of the decay box 2;

[0053] The pick-up and placement device 5 is placed on the navigation track 4 and moves along the navigation track 4 to transfer the waste bag to the decay box 2 .

[0054] As part of an overall system, the treatment device 1 is the core area of ​​radioactive solid waste treatment, which contains all other components and provides a safe environment for treating radioactive waste. The waste shielding device 3 is located inside the treatment device 1 and is fixedly connected to the bottom surface of the treatment device 1. There is a space inside for placing waste bags to reduce radiation leakage and protect operators.

[0055] A sensor is fixedly connected to the inner wall of each decay box 2, which is used to detect parameter information of the waste bag in the decay box 2 to ensure the correct placement of the waste bag and the effective use of the space in the box. The navigation track 4 is fixedly placed on the bottom surface inside the processing device 1. A certain first distance is maintained between the side surface of the decay box 2 to provide a moving path for the pick-up and placement device 5. The pick-up and placement device 5 is placed on the navigation track 4 and can move along the navigation track 4. When the system is running, the pick-up and placement device 5 takes the waste bag out of the waste shielding device 3 and transfers it to the decay box 2 for radioactive decay treatment.

[0056] For further information, please refer to Figure 4 The pick-and-place device 5 includes: a base 501 and a support rod.

[0057] One end of the support rod is fixedly placed on the outer surface of the base 501 on a side away from the decay box 2, and the other end extends vertically upward;

[0058] The top of the base 501 extends inward to form a receiving cavity, and the receiving cavity is used to hold the fallen waste bag.

[0059] As the base part of the pick-and-place device 5, the base 501 is used to support the entire device and enable it to move along the navigation track 4. The function of the support rod is to provide additional stability or serve as a support for operating other components (such as a mechanical gripper).

[0060] The top of the base 501 extends inward to form a receiving cavity, which is specially designed to hold dropped waste bags. In this way, if waste bags accidentally fall during the transfer process, they can be safely captured and kept in the receiving cavity to prevent leakage of radioactive materials and environmental pollution. This design ensures the safety and stability of the waste bags during the processing process, and also facilitates the operator to recycle and process the dropped waste bags.

[0061] For further information, please continue to refer to Figure 4 The other end of the support rod is provided with a slide rail, and the slide rail includes a first slide rail 502, a second slide rail 503 and a third slide rail 504.

[0062] One end of the first slide rail 502 is connected to the support rod, and the other end is perpendicular to the support rod and extends in a direction close to the decay box 2;

[0063] The upper surface of the second slide rail 503 is connected to the first slide rail 502, and both ends extend in a direction parallel to the decay box 2; the second slide rail 503 moves along the first slide rail 502;

[0064] One end of the third slide rail 504 is connected to the lower surface of the second slide rail 503 , and the other end extends toward the pick-and-place device 5 in a direction parallel to the support rod; the third slide rail 504 moves along the second slide rail 503 .

[0065] The first slide rail 502 provides a connection between the waste pick-up and placement device and the decay box 2. The second slide rail 503 provides the ability to move horizontally, so that the pick-up and placement device 5 can adjust its position along the length or width direction of the decay box 2 through the third slide rail 504, thereby determining the delivery point. The design of this triple slide rail system enables the pick-up and placement device 5 to move in multiple dimensions, so that the waste bag can be accurately transferred from the waste shielding device 3 to the designated decay box 2. Such a design improves the flexibility of operation and the applicability of the system, and ensures the efficiency and safety of the waste treatment process. In this embodiment, the first slide rail 502 preferably extends in a direction close to the decay box 2, and extends to the edge of the decay box 2 away from the first slide rail. For the second slide rail 503, in order to realize the movement of the second slide rail 503 along the first slide rail 502, the second slide rail 503 is fixedly connected to the first slide rail 502 by a slider.

[0066] At the same time, since the base 501 can move along the navigation track 4, and the length of the navigation track 4 can be adjusted, the third slide rail 504 can move along the second slide rail 503 to the far end of the farthest decay box 2 through the cooperation of the navigation track 4, the base 501 and the second slide rail 503. If the length of the navigation track 4 is adjusted, the length of the second slide rail 503 should also be adjusted accordingly to achieve full coverage in the horizontal direction.

[0067] Preferably, Figure 2 In the embodiment shown, the first end of the navigation track 4 (i.e., the end away from the waste shielding device 3) extends to the side wall of the processing device 1, and the second end (i.e., the end close to the waste shielding device 3) is placed at the edge of the waste shielding device 3. When the base 501 moves to the end of the first end of the navigation track 4, the projection of the right end of the second slide rail 503 (i.e., the end away from the waste shielding device 3) in the vertical direction should extend to the edge of the base 501; when the base 501 moves to the end of the second end of the navigation track 4, the left end of the second slide rail 503 (i.e., the end close to the waste shielding device 3) should extend to the side wall of the processing device 1.

[0068] At this time, the third slide rail 504 can move along the second slide rail 503, and the second slide rail 503 can drive the third slide rail 504 to move along the first slide rail 502, so as to achieve full coverage of the decay box 2. It can be understood that the aforementioned extension to the side wall means that no friction force that resists movement is generated, and the extension lengths at both ends of the second rail 503 always exist, and the description of the above embodiment is only convenient for explanation in the case of end points.

[0069] Furthermore, there is a second distance between the other end of the first slide rail 502 and the inner wall of the processing device 1, and the range of the second distance is 0-50 mm.

[0070] Since the entire pick-and-place device needs to move along the navigation track 4 to adjust the position, the second distance is set to ensure that the first slide rail 502 has enough space to move and avoid collision or friction with the inner wall of the processing device 1. In this embodiment, the length of the second distance is preferably 25 mm.

[0071] Furthermore, a grabbing member 507 is provided on the third slide rail 504 . The grabbing member 507 is disposed at an end of the third slide rail 504 away from the second slide rail 503 and can be extended and retracted in a vertical direction.

[0072] The grabbing member 507 is arranged at one end of the third slide rail 504 away from the second slide rail 503, that is, the grabbing member 507 is located at the far end of the pick-and-place device 5, close to the waste bag to be operated. It can be moved up and down as needed to facilitate grabbing and releasing the waste bag. This vertical flexibility enables the grabbing member 507 to adapt to waste bags of different heights and positions, so as to accurately place or remove the waste bag in the shielding container or 301 decay box 2.

[0073] Furthermore, the third slide rail 504 is also provided with a first camera device 506 and a dose detection device 505.

[0074] The first camera device 506 is fixedly placed on the side wall of the third slide rail 504, and is used to detect the accommodation state of the decay box 2; the dose detection device 505 is fixedly placed on the side wall of the third slide rail 504, and is used to detect the radiation dose in the processing device 1 in real time.

[0075] Specifically, the first camera device 506 is fixedly placed on the side wall of the third slide rail 504, so that the camera device 506 can change the viewing angle as the third slide rail 504 moves, thereby covering various parts of the decay box 2. The first camera device 506 can detect the accommodation state of the decay box 2, including monitoring the placement position of the waste bag, the space utilization rate inside the decay box 2, and whether there is a vacant position to place a new waste bag. The visual feedback provided by the first camera device 506 helps the operator or the automation system to judge and process the state of the decay box 2.

[0076] The dose detection device 505 is also fixed on the side wall of the third slide rail 504, and is arranged side by side with the first camera device 506 or located at a different position, depending on the design requirements. The dose detection device 505 can monitor the change of the radiation level and issue an alarm when the radiation dose exceeds the safety threshold, so as to take corresponding safety measures. By real-time detection of the radiation dose in the processing device 1, the safety of the operating environment is ensured.

[0077] The combined use of the two devices improves the automation level and safety of the radioactive solid waste treatment system. The first camera device 506 provides visual monitoring, while the dose detection device 505 provides real-time data on radiation safety. Together, the two ensure the effectiveness of the waste treatment process and the safety of operators.

[0078] For further information, please refer to Figure 5 , the waste shielding device 3 comprises a shielding container 301 for containing the waste bag; a first identification code is provided on the outer wall of the shielding container 301, and a second identification code is provided on the waste bag;

[0079] A shielding cover 302 is provided on the top of the shielding container 301, and the shielding cover 302 is threadedly connected to the shielding container 301; a fixing component 303 and a cover removal component are provided outside the shielding container 301, the fixing component 303 is used to fix and move the shielding container 301, and the cover removal component is used to remove the shielding cover 302.

[0080] Specifically, the shielding container 301 is used to hold and transfer waste bags to reduce radiation leakage and provide a safe storage environment. The shielding cover 302 is connected to the shielding container 301 by threads, ensuring the sealing of the shielding cover 302 and the convenience of opening.

[0081] The first identification code and the second identification code are respectively provided on the outer wall of the shielding container 301 and the waste bag, and the first identification code and the second identification code are used to record and track the processing process of the waste bag, including the time of entering the decay room, the decay cycle and other information. When the waste bag is transferred to the inside of the processing device 1 through the shielding container 301, due to the influence of radiation, the staff cannot open the shielding cover 302 to scan the code at this time, so the corresponding first identification code is set on the shielding container 301 for pre-scanning to prevent the staff from being exposed to radiation.

[0082] The fixing assembly 303 is used to fix and move the shielding container 301. In this embodiment, a locking device (not shown) is also included to facilitate positioning the shielding container 301 at a specific position in the processing device 1.

[0083] The cover removal assembly 304 is used to remove the shielding cover 302 so as to remove the waste bag from the shielding container 301. The cover removal assembly 304 can be a mechanical arm or other mechanical device, which can cooperate with the threaded connection of the shielding cover 302 to achieve precise operation.

[0084] For further information, please refer to Figure 6 , further comprising a code scanning device 6, which is placed in the processing device 1 and fixedly connected to the bottom surface of the processing device 1. This ensures the stability and accuracy of the code scanning device 6 during operation.

[0085] The code scanning device 6 is used to scan the first identification code after the shielding container 301 is placed at the designated position, and scan the second identification code after the decay period ends.

[0086] In this embodiment, the code scanning device 6 includes a bracket 601 and a code scanner 602. The code scanner 602 is detachably fixed to the bracket 601, so that the staff can scan the code by hand or by fixing the code.

[0087] When the shielding container 301 is placed at the designated position in the processing device 1, the code scanning device 6 is used to scan the first identification code on the outer wall of the shielding container 301. This step is usually used to record the arrival time and location information of the waste bag in the shielding container and the processing status of its contents.

[0088] After the decay period is over, the code scanning device 6 is used to scan the second identification code on the waste bag. This step helps to record the time when the waste bag is processed and confirm that the waste bag has met the decay standard and can be safely processed or stored.

[0089] Furthermore, it also includes a second camera device 7, which is placed on the side wall of the processing device 1 close to the top and is used to detect the placement and removal of the waste bag.

[0090] The second camera device 7 is used to monitor the removal and placement of the waste bag in the processing device 1 in real time. This includes monitoring the process of the waste bag being taken out of the shielding container 301 and placed in the decay box 2. By providing visual feedback, the second camera device 7 helps the operator or the automated system to ensure the correct handling of the waste bag and avoid operational errors or omissions. In addition, the second camera device 7 can also be used to record key steps in the operation process for subsequent analysis or auditing.

[0091] The addition of the second camera device 7 further enhances the monitoring capability of the radioactive solid waste treatment system. It complements the first camera device 506, providing dual monitoring of the waste treatment process, ensuring efficient and safe operation of the system. By installing cameras at different locations of the treatment device 1, the entire waste bag treatment process can be covered, thereby improving the overall performance and reliability of the system.

[0092] In a second aspect, the present invention provides a method for treating solid radioactive waste, using any of the above-mentioned solid radioactive waste treatment systems, comprising:

[0093] The taking and placing device 5 takes out the waste bag from the waste shielding device 3;

[0094] Determine the capacity of the decay box 2 according to the data of the sensor, and open the corresponding decay box 2;

[0095] The picking and placing device 5 moves along the navigation track 4 to transfer the waste bag to the top of the decay box 2 and put it into the decay box.

[0096] First, take out the waste bag. The cover removal assembly 304 first removes the shielding cover 302 to expose the waste bag, and uses the pick-and-place device 5 to take out the waste bag therefrom. In this step, the gripping member 507 of the pick-and-place device 5 moves downward to clamp and lift the waste bag.

[0097] Secondly, the capacity of the decay box 2 is determined. The capacity of the decay box 2 is determined based on the data provided by the sensor in the decay box 2. The sensor can detect the height of the waste bag, the space utilization rate in the box, or other relevant parameters to determine whether there is enough space to accommodate a new waste bag.

[0098] Open the corresponding decay box 2. Once the capacity of the decay box 2 is determined, the corresponding decay box 2 will be opened so that the retrieval device 5 can put the waste bag in. The opening operation may be automatic or remotely controlled by an operator.

[0099] Next, the pick-and-place device 5 moves and puts in the waste bag. The pick-and-place device 5 moves along the navigation track 4 and transfers the waste bag to the top of the designated decay box 2. After reaching the designated position, the pick-and-place device 5 puts the waste bag into the decay box 2. In this step, the waste bag is transported along the second track and the first track in sequence.

[0100] Furthermore, the plurality of decay boxes 2 are put into use in sequence according to a preset order.

[0101] Furthermore, when the sensor detects that the parameter of the waste bag in the decay box 2 exceeds the preset parameter, the box cover of the decay box 2 is not opened.

[0102] When the sensor detects that the parameter of the waste bag in the decay box 2 does not exceed the preset parameter, the box cover of the decay box 2 is opened.

[0103] Specifically, during the processing, multiple decay boxes 2 are put into use in a preset order. This order may be based on the number, location, capacity or other logical order of the decay boxes 2. Such an order helps to ensure that the waste bags are processed according to a specific decay plan or capacity management strategy.

[0104] In this embodiment, it is preferred that the decay boxes 2 are used in sequence, and the next decay box 2 is used after the capacity of the current decay box 2 reaches the preset value. At the same time, this usage method can control the decay time required for the waste bags in each decay box 2 to be close, and better control the time.

[0105] When the sensor detects that the parameters (such as weight, volume, radiation level, etc.) of the waste bag in the decay box 2 exceed the preset parameters, the system will not open the lid of the decay box 2. This is to prevent waste bags that are overloaded or exceed the safety threshold from being placed in the decay box 2, ensuring the safety of the treatment process.

[0106] On the contrary, when the sensor detects that the parameters of the waste bag in the decay box 2 do not exceed the preset parameters, the system will open the box cover of the decay box 2 to allow the picking and placing device 5 to put in a new waste bag.

[0107] Based on the above, the complete process is:

[0108] Step 1: Remove the waste bag;

[0109] Step 2: The system selects the next available decay box 2 according to the preset order;

[0110] Step 3: The sensor detects the selected decay box 2 to confirm whether its internal parameters meet the conditions for being put into use;

[0111] Step 4: If the parameter detected by the sensor exceeds the preset parameter, the system will record this situation and skip the decay box 2 and continue to detect the next decay box 2;

[0112] Step 5: If the parameter detected by the sensor does not exceed the preset parameter, the system will instruct to open the cover of decay box 2;

[0113] Step 6: The picking and placing device 5 puts the waste bag into the opened decay box 2, and then the system closes the box cover;

[0114] Step 7: After the decay period ends, the retrieval device 5 takes out the waste bag, and the staff scans the code of the waste bag for record.

[0115] In summary, the use of the automated pick-and-place device 5 and sensors reduces the direct contact between operators and radioactive waste and improves the safety of operations. At the same time, the automated system can accurately control the process of picking and placing waste bags, reducing the risk of human error. Multiple decay boxes 2 are put into use in sequence according to a preset order, ensuring that the waste bags are processed according to a specific decay plan or capacity management strategy. This sequential processing method helps to better control the decay time and processing efficiency of the waste bags. The sensor monitors the parameters of the waste bags in the decay box 2 in real time. When the parameters exceed the preset parameters, the system will not open the lid of the decay box 2 to prevent waste bags that are overloaded or exceed the safety threshold from being placed in, ensuring the safety of the processing process. By scanning the first identification code and the second identification code, the whole process tracking and management of the waste bags is achieved. This helps to record the processing history of the waste bags and ensure the traceability of the waste treatment process.

For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
