Description

Technical Field

[0001] This utility model relates to the field of nuclear power engineering or spent fuel reprocessing technology, specifically to a sampling device for dry waste resin and dry activated carbon used in nuclear power or spent fuel reprocessing. Background Technology

[0002] Resin and activated carbon sampling equipment has important application value in the nuclear power field, providing key data support for reactor water chemistry control and radioactivity level monitoring.

[0003] For dry resin sampling, one sampling device in the related technology uses a retractable sampling tube to enter and exit the dry resin delivery pipeline. The sampling tube is equipped with a sampling port. During sampling, the sampling tube enters the dry resin delivery pipeline with the sampling port facing upward to receive the dry resin. After sampling, the sampling tube retracts and rotates so that the sampling port faces downward to pour the sample into the collection tank below. Then, a blower is used to blow the sample through the pipeline to the sampling bottle to complete the sampling. The gas is discharged into the gas treatment system for processing.

[0004] When the samples are blown into the sampling bottle by the fan, some samples may be blown out of the sampling bottle due to the airflow, which poses a risk of leakage. Utility Model Content

[0005] Based on the above description, this utility model provides a sampling device for dry waste resin and dry activated carbon in nuclear power or spent fuel reprocessing, in order to solve the problem that when the sample is blown into the sampling bottle by the blower, some samples are easily blown out of the sampling bottle by the airflow, which poses a risk of leakage.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This application provides a sampling device for dry waste resin and dry activated carbon used in nuclear power or spent fuel reprocessing, comprising: A sampling device, comprising a sampling tube and a receiving trough, wherein a sampling port is provided on the side wall of the sampling tube, the sampling tube is axially movable and rotatable about its own axis, and the receiving trough is used to receive the sample output from the sampling port; A sample delivery device, comprising a sample delivery tube and a blower, wherein one end of the sample delivery tube is connected to the output end of the blower, and the sample delivery tube is located below the receiving trough and communicates with the receiving trough; A sample receiving device includes an exhaust pipe and a lifting mechanism. The exhaust pipe is distributed vertically at both ends. The upper end of the exhaust pipe is connected to the waste gas treatment system. The end of the sample delivery pipe away from the fan is inserted into the exhaust pipe and exits from the lower end of the exhaust pipe. The lifting mechanism is located below the exhaust pipe and is used to grab a sampling bottle with a top opening and drive the sampling bottle to rise and fall. The sampling bottle can rise until the end of the sample delivery pipe away from the fan is inserted into the sampling bottle. The exhaust pipe has an end plate at its lower end, which covers the lower opening of the exhaust pipe. The sample delivery pipe passes through the end plate. When the lifting mechanism drives the sampling bottle to rise until the bottle opening abuts against the end plate, the end plate covers the bottle opening of the sampling bottle, and the exhaust pipe is connected to the sampling bottle.

[0007] Preferably, the end plate is provided with an exhaust hole, and when the sampling bottle abuts against the end plate, it communicates with the exhaust pipe through the exhaust hole.

[0008] Preferably, the end plate is provided with a sealing ring on the side away from the exhaust pipe, and the sampling bottle is pressed against the end plate to form a seal.

[0009] Preferably, the inner cavity of the sampling bottle includes an inlet area and a storage area distributed vertically, the inlet area and the storage area are connected by a communication port, and the sampling bottle is provided with a switch structure for opening or closing the communication port, which is adapted to drive the switch structure to open the communication port when the sample delivery tube is inserted into the sampling bottle to the storage area.

[0010] Preferably, the diameter of the connecting port is smaller than the diameter of the storage area. The switch structure includes a movable baffle disposed in the storage area. The movable baffle is rotatably connected to the inner wall of the sampling bottle about a horizontal pivot. The movable baffle can be rotated to open or cover the connecting port. An elastic element is provided between the movable baffle and the sampling bottle. When the movable baffle rotates from the state of covering the connecting port to the state of opening the connecting port, it overcomes the elastic force of the elastic element.

[0011] Preferably, the elastic element includes a torsion spring.

[0012] Preferably, the lifting mechanism includes a clamping component and a lifting component, wherein the clamping component is used to clamp the sampling bottle and the lifting component is used to drive the clamping component to move up and down.

[0013] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: This application utilizes a sampling device, a feeding and rotating shaft, and a sample receiving device. In the sampling device, the sampling tube moves axially into the resin delivery pipe and receives the sample through a sampling port. The sampling tube then exits the resin delivery pipe and rotates so that the sampling port faces downwards, allowing the sample to be poured out from the sampling port into a receiving trough, completing the sample retrieval process. The sample in the receiving trough is fed into the feeding tube, and a fan blows the sample along the feeding tube to the sample receiving device. In the sample receiving device, a lifting mechanism grabs the sampling bottle and rises it to abut against the lower end plate of the exhaust pipe. At this point, the feeding tube is inserted into the sampling bottle, and the sampling bottle and exhaust pipe are connected. The sample exits from the feeding tube and enters the sampling bottle to complete the sampling. Excess gas is discharged into the exhaust pipe and sent to the waste gas treatment system for processing. During the process of the sample being blown to the sampling bottle, the end plate prevents the sample from overflowing, thus avoiding the risk of leakage. Attached Figure Description

[0021] Reference Figure 1 As shown, this application provides a sampling device for dry waste resin and dry activated carbon for nuclear power or spent fuel reprocessing, including a sampling device 1, a sample delivery device 2 and a sample receiving device 3.

[0022] Reference Figure 1 and Figure 2 As shown, the sampling device 1 is used to take samples from the resin delivery pipe 10. The sampling device 1 includes a sampling tube 11 and a receiving trough 12. The sampling tube 11 has a sampling port on its side wall. The sampling tube 11 can move axially and rotate around its own axis. The receiving trough 12 is used to receive the sample output from the sampling port.

[0023] Reference Figure 2 As shown, specifically, the sampling device 1 is horizontally mounted on the mounting frame 4. A motor on the mounting frame 4 drives the sampling tube 11 to rotate around its own axis. The motor and the sampling tube 11 are mounted on a base, which is mounted on the mounting frame 4 via a linear module parallel to the axis of the sampling tube 11. The linear module drives the motor and the sampling tube 11 to move axially along the sampling tube 11. Correspondingly, an interface for the sampling tube 11 to enter and exit is provided on the resin delivery pipe 10. The sampling tube 11 extends into the resin delivery pipe 10 and is rotated until the sampling port faces upwards. After the sample enters the sampling tube 11 from the sampling port, the sampling tube 11 exits the resin delivery pipe 10 to remove the sample.

[0024] Reference Figure 2 As shown, the receiving trough 12 is fixed on the mounting bracket 4 and located below the sampling tube 11. Specifically, a sleeve 13 is connected to the top of the receiving trough 12. The sleeve 13 is coaxially fitted outside the sampling tube 11 and connected to the interface on the resin delivery pipe 10. The bottom of the sleeve 13 is connected to the receiving trough 12. After the sampling tube 11 takes out the sample, it moves until the receiving port is located inside the sleeve 13. Then, the sampling tube 11 is rotated so that the sampling port faces downwards and the sample is poured out into the receiving trough 12.

[0025] Reference Figure 2 As shown, the sample delivery device 2 is used to deliver the extracted sample into the sampling bottle 5. The sample delivery device 2 includes a sample delivery tube 21 and a blower 22. One end of the sample delivery tube 21 is connected to the output end of the blower 22. The sample delivery tube 21 is located below the receiving trough 12 and is connected to the receiving trough 12.

[0026] Reference Figure 2 As shown, the sample delivery tube 21 and the blower 22 are both fixed on the mounting bracket 4. After the sample enters the receiving trough 12, it enters the sample delivery tube 21 from the bottom of the receiving trough 12. The blower 22 blows air to transport the sample in the sample delivery tube 21 to the other end of the sample delivery tube 21. The other end of the sample delivery tube 21 extends to the sample receiving device 3.

[0027] Reference Figure 1 and Figure 3 As shown, the sample receiving device 3 is used to receive the sample output from the sample delivery tube 21. The sample receiving device 3 is set on the frame 6. The frame 6 and the mounting frame 4 are located in different areas within the factory area, so that the sample receiving device 3 is in a different area from the sampling device 1 and the sample delivery device 2, and personnel do not need to enter the higher radiation area where the resin delivery pipe 10 is located.

[0028] Reference Figure 3 As shown, the sample receiving device 3 includes an exhaust pipe 31 and a lifting mechanism. The exhaust pipe 31 is distributed vertically at both ends. The upper end of the exhaust pipe 31 is connected to the waste gas treatment system. The end of the sample delivery pipe 21 away from the fan 22 is inserted into the exhaust pipe 31 and exits from the lower end of the exhaust pipe 31. The lifting mechanism is located below the exhaust pipe 31. The lifting mechanism is used to grab the sampling bottle 5 with the top opening and drive the sampling bottle 5 to rise and fall. The sampling bottle 5 can rise until the end of the sample delivery pipe 21 away from the fan 22 is inserted into the sampling bottle 5.

[0029] Reference Figure 3 As shown, specifically, the exhaust pipe 31 is fixed on the frame 6 and is set vertically, and the sample delivery pipe 21 enters the exhaust pipe 31 from the side wall of the exhaust pipe 31 and extends to exit from the lower end of the exhaust pipe 31.

[0030] Reference Figure 3 As shown, the lifting mechanism includes a clamping assembly 32 and a lifting assembly 33. The clamping assembly 32 is used to clamp the sampling bottle 5, and the lifting assembly 33 is used to drive the clamping assembly 32 to move up and down. The clamping assembly 32 includes a horizontally arranged support plate with a notch on one side. A flange is provided on the outer wall of the sampling bottle 5 near the bottle opening. The sampling bottle 5 can be inserted into the notch and supported on the support plate by the flange, so that the lifting of the support plate drives the lifting of the sampling bottle 5. The lifting assembly 33 can be a cylinder or a vertically arranged linear module, selected according to actual needs. This embodiment uses a cylinder as an example.

[0031] Reference Figure 3 and Figure 4 As shown, in order to prevent the sample from overflowing from the sampling bottle 5, an end plate 34 is provided at the lower end of the exhaust pipe 31. The end plate 34 covers the lower end of the exhaust pipe 31. The sample delivery pipe 21 passes through the end plate 34. When the lifting mechanism drives the sampling bottle 5 to rise until the bottle mouth abuts against the end plate 34, the end plate 34 covers the bottle mouth of the sampling bottle 5, and the exhaust pipe 31 is connected to the sampling bottle 5.

[0032] Reference Figure 4 and Figure 5 As shown, an exhaust hole 341 is provided on the end plate 34, which connects the inside and outside of the exhaust pipe 31. When the sampling bottle 5 abuts against the end plate 34, it connects to the exhaust pipe 31 through the exhaust hole 341. In this embodiment, a flange is provided at the lower end of the exhaust pipe 31, and the end plate 34 is fixedly connected to the flange by bolts.

[0033] Before the sample is output from the sample delivery tube 21, the lifting mechanism first grabs the sampling bottle 5 and rises it to abut against the lower end plate 34 of the exhaust pipe 31. At this time, the sample delivery tube 21 is inserted into the sampling bottle 5, and the sampling bottle 5 and the exhaust pipe 31 are connected. After the sample is output from the sample delivery tube 21, it enters the sampling bottle 5 to complete the sampling. Excess gas is discharged into the exhaust pipe 31 and sent to the waste gas treatment system for processing. During the process of the sample being blown into the sampling bottle 5, the sample is not easy to overflow from the sampling due to the obstruction of the end plate 34, thus avoiding the risk of leakage.

[0034] Reference Figure 4 and Figure 5 As shown, a sealing ring 35 is further provided on the side of the end plate 34 away from the exhaust pipe 31. When the sampling bottle 5 abuts against the end plate 34, the sealing ring 35 is squeezed to form a seal. The sealing ring 35 can prevent gas from leaking from the gap between the end plate 34 and the sampling bottle 5.

[0035] Reference Figure 5 As shown, the inner cavity of the sampling bottle 5 includes an inlet area 51 and a storage area 52 distributed vertically. The inlet area 51 and the storage area 52 are connected by a connecting port 53. The sampling bottle 5 is provided with a switch structure for opening or closing the connecting port 53, which is suitable for driving the switch structure to open the connecting port 53 when the sample delivery tube 21 is inserted into the sampling bottle 5 to the storage area 52.

[0036] Reference Figure 5 As shown, both the inlet area 51 and the storage area 52 are cylindrical. The diameter of the connecting port 53 is smaller than that of the storage area 52. The switch structure includes a movable baffle 54 disposed in the storage area 52. The movable baffle 54 is rotatably connected to the inner wall of the sampling bottle 5 about a horizontal pivot. The movable baffle 54 can be rotated to open or cover the connecting port 53. An elastic element is provided between the movable baffle 54 and the sampling bottle 5. When the movable baffle 54 rotates from the state of covering the connecting port 53 to the state of opening the connecting port 53, it overcomes the elastic force of the elastic element.

[0037] Reference Figure 5 As shown, the diameter of the inlet area 51 is smaller than the diameter of the storage area 52, and the lower end of the inlet area 51 forms a connecting port 53. The movable baffle 54 is a circular plate with a diameter larger than the diameter of the connecting port 53 and smaller than the diameter of the storage area 52, so that the movable baffle 54 can completely cover the connecting port 53 and can rotate freely.

[0038] Reference Figure 5 As shown, one side of the movable baffle 54 is rotatably connected to the inner wall of the sampling bottle 5 via a hinge. Specifically, an mounting plate for installing the movable baffle 54 can be provided on the inner wall of the sampling bottle 5. The elastic element can be a torsion spring, so that the movable baffle 54 is kept covering the communication port 53 by the spring force, thereby keeping the communication port 53 closed during normal transportation and preventing sample leakage.

[0039] Reference Figure 5 As shown, in this embodiment, the end of the sample delivery tube 21 is connected to a sampling needle tube 20, which is inserted into the sampling bottle 5 to inject the sample into the sampling bottle 5.

[0040] Reference Figure 3 As shown, a positioning station is further provided on the frame 6 directly below the exhaust pipe 31. The sampling bottle 5 is transported by a transfer trolley 7, which is equipped with a shielding container 8. The top of the shielding container 8 is designed to be open, so that when the sampling bottle 5 is placed in the shielding container 8, the top protrudes outside the shielding container 8, allowing the clamping assembly 32 to grasp the sampling bottle 5. At the same time, a movable bottle cap 9 is provided on the shielding container 8 to open or close the top opening of the sampling bottle 5 placed in the shielding container 8. The bottle cap 9 can be automatically opened by electric or pneumatic control.

[0041] A passageway for the transfer trolley 7 to enter and exit is provided on the frame 6 at the positioning station. The transfer trolley 7 is pushed into the positioning station through the passageway, and a limit switch is installed on the frame 6. After the transfer trolley 7 is pushed into place, the limit switch is triggered, indicating that the transfer trolley 7 has reached its position, at which point personnel can leave the equipment area. The specific positioning method is a conventional technical means and will not be described in detail here.

[0042] During sampling, the support plate is lowered to a height below the flange of the sampling bottle 5 on the transfer trolley 7. Personnel push the transfer trolley 7 into the positioning position, during which the sampling bottle 5 is inserted into the notch on the support plate. After the transfer trolley 7 is in place, personnel leave. Then, the bottle cap 9 on the shielding tank 8 automatically opens, and the support plate rises to lift the sampling bottle 5 until it abuts against the end plate 34. At this point, the sample delivery tube 21 is inserted into the sampling bottle 5. Next, the sampling device 1 operates to retrieve the sample from the resin delivery pipe 10. The sample is input into the sample delivery tube 21 and blown into the sampling bottle 5 by the fan 22. Excess gas is discharged into the waste gas treatment system through the exhaust pipe 31 for treatment. After the sample enters the sampling bottle 5, the clamping assembly 32 lowers to place the sampling bottle 5 into the shielding tank 8. The bottle cap 9 automatically closes to seal the opening of the sampling bottle 5 to shield radiation. At this point, personnel can transport the transfer trolley 7 to the laboratory for testing. This automates the sampling process.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
