Description

Technical Field

[0001] The present invention relates to the field of nuclear power technology, and in particular to a concrete HIC container leveling device for nuclear power. Background Art

[0002] Based on the principle of waste minimization, volume reduction technology is widely used in the waste treatment systems of nuclear power plants. After volume reduction, the dispersed radioactive waste is stored in steel drums and cannot be disposed of directly. It needs to be placed in high-integrity containers (HIC containers) and poured with concrete mortar. After the mortar solidifies, the HIC container and the steel drum are connected to form a concrete HIC container before final treatment.

[0003] The top of the concrete HIC container must meet the requirements of the "High-Integrity Concrete Container for Low- and Intermediate-Level Radioactive Waste" and must be smooth and free of water. Therefore, after mortar pouring, the top of the mortar must be smoothed and excess mortar scraped off to ensure a smooth top after the mortar solidifies. Due to the radioactive nature of the waste being processed, an automated smoothing device was designed to replace manual smoothing operations. Summary of the Invention

[0004] Based on the above description, the present invention provides a concrete HIC container leveling device for nuclear power, which can automatically level the top of the mortar in the HIC container instead of manual work.

[0018] The active rack can move to engage with or disengage from the active gear as the scraper moves, and when the active rack is engaged with the gear, the driven rack is driven to move in the opposite direction by the gear when the active rack moves. When the scraper moves to an area between the first position and the second position, the active rack remains engaged with the gear, and when the scraper moves to an area outside the first position and the second position, the active rack is disengaged from the gear.

[0024] Preferably, a vibration table is provided on the frame, and the vibration table is located between the first workstation and the second workstation, and the HIC container is used to be placed on the vibration table.

[0025] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0026] 1. The present application sets a first station and a second station on the frame, and a space for accommodating the HIC container is formed between the first station and the second station. The HIC container is placed between the first station and the second station for grouting, capping, and other operations. A scraper that can move between the first station and the second station is provided, and the top of the mortar in the HIC container is smoothed by the movement of the scraper; a receiving tray is provided in the second station to contact the side wall of the HIC container, and the receiving tray receives the excess mortar scraped off by the scraper, thereby preventing the excess mortar from overflowing onto the outer wall of the container. The scraper and the receiving tray cooperate to achieve the purpose of smoothing the top of the mortar in the HIC container and preventing mortar from remaining on the outer wall of the container. The receiving tray can be moved to a setting where it fits in or out of contact with the side wall of the HIC container. After the smoothing operation is completed, the receiving tray can be moved to a position where it is disengaged from the side wall of the HIC container and moved to a position away from the HIC container, so that personnel can clean the receiving tray at a distance from the HIC container. The transmission mechanism transmits the power of the scraper's movement to the receiving tray, driving its movement. During the scraper's smoothing stroke from the first to the second station, the transmission mechanism drives the receiving tray to align with the HIC container to receive the mortar. During the scraper's reset stroke, the transmission mechanism moves the receiving tray away from the HIC container. This mechanism achieves coordinated control of the scraper and receiving tray movements, eliminating the need for manual movement of the relay tray. The scraper's movement is driven by a drive assembly, which can be controlled by automated equipment such as electric or pneumatic devices. Personnel only need to clean the receiving tray at a distance from the HIC container in the second station to avoid contact with the HIC container.

[0027] 2. The transmission structure of the present application realizes the linkage between the movement of the scraper and the receiving tray. During the working stroke of the scraper, the receiving tray is ensured to be moved to a state of contact with the HIC container before the scraper moves to the second station. This ensures that any mortar that overflows before the scraper moves to the second station is received by the receiving tray, preventing the mortar from overflowing onto the outer wall of the HIC container. After the receiving tray contacts the HIC container, it is disconnected from the scraper, which does not affect the free movement of the scraper between the second position and the second station, so that all excess mortar is scraped into the receiving tray. In addition, the transmission mechanism is composed of gears and racks, which has the advantages of simple structure and low cost.

[0028] 3. This application sets a third station on the frame and a cleaning mechanism at the third station. When the scraper moves to the third station, the scraper is cleaned by the cleaning mechanism to avoid the mortar remaining on the scraper from affecting the surface flatness of the scraper after solidification, ensuring that the scraper remains clean each time the leveling operation is performed, so as to improve the leveling effect of the mortar in the HIC container.

[0040] Reference Figure 1-4 As shown, the present application provides a concrete HIC container smoothing device for nuclear power, which includes a frame 1 and a smoothing mechanism and a receiving tray 4 arranged on the frame 1. The frame 1 is provided with a first station and a second station spaced apart along a first horizontal direction, and the HIC container is used to be placed between the first station and the second station. The smoothing mechanism includes a scraper 2 and a drive assembly 3. The scraper 2 can move between the first station and the second station along the first direction. The drive assembly 3 connects the scraper 2 and the frame 1 and is used to drive the scraper 2 to move. It is suitable for smoothing the top of the mortar in the HIC container between the first station and the second station when the scraper 2 moves from the first station to the second station. The receiving tray 4 is connected to the frame 1 and is located in the second station. The receiving tray 4 can move along the first direction and can move to fit the side wall of the HIC container between the first station and the second station. The receiving tray 4 is used to receive excess mortar scraped off by the scraper 2.

[0041] Specifically, the frame 1 is designed according to equipment installation requirements. The smoothing mechanism and receiving tray 4 are mounted on top of the frame 1. The top of the frame 1 is at a certain height above the ground. When the HIC container is placed between the first and second workstations, the top height is flush with the bottom height of the scraper 2. The scraper 2 is designed as an elongated strip, with its length parallel to a second direction that is perpendicular to the first direction and horizontal. As the scraper 2 moves, it smoothes the top of the mortar through its bottom.

[0042] Reference Figure 1-2As shown, when the scraper 2 moves to smooth the top of the mortar, to prevent the mortar from overflowing from both sides of the HIC container in the second direction, the scraper 2 is connected to two baffles 6. The two baffles 6 are spaced apart along a second direction that is horizontal and perpendicular to the first direction. When the scraper 2 smoothes the top of the mortar in the HIC container, the two baffles 6 prevent excess mortar from overflowing from both sides of the HIC container in the second direction. Specifically, the baffle 6 is connected to the side of the scraper 2 near the second station and extends away from the scraper 2 in the first direction. When the scraper 2 is moved above the HIC container, the two side plates are respectively located above the two side walls of the HIC container in the second direction, and the side plates are in contact with the top surfaces of the side walls of the HIC container. The slurry scraped by the scraper 2 is retained between the two side plates by the two side plates, and the scraped mortar moves with the scraper 2 toward the second station, preventing the mortar from overflowing from both sides of the HIC container.

[0043] Reference Figure 2-3 As shown, two rails 11 are provided on the frame 1. The rails 11 extend in a first direction, and the two rails 11 are spaced apart in a second direction, with the scraper 2 located between the two rails 11. The drive assembly 3 includes two mounting seats 31 and two motors 32. The two mounting seats 31 are respectively connected to rail 11 wheels adapted to the rails 11. The two mounting seats 31 are respectively mounted on the two rails 11 via the rail 11 wheels. The two mounting seats 31 are connected by a connecting shaft 34 to keep the rail 11 wheels on the two support seats on the two rails 11 and achieve synchronous movement of the two mounting seats 31. The two mounting seats 31 and the connecting shaft 34 form a drive bracket that can move along the first direction on the two rails 11. The two motors 32 are respectively mounted on the two mounting seats 31 and are used to drive the rail 11 wheels on the corresponding mounting seats 31 to rotate, thereby achieving the purpose of driving the mounting seats 31 to move on the rails 11. Specifically, a limiting roller is further connected to the mounting base 31. The limiting roller axis is parallel to the second direction and is rotatably connected to the mounting base 31. The limiting roller is located below the track 11 and contacts the bottom surface of the track 11. The limiting roller cooperates with the track 11 wheels to enable the mounting base 31 to move stably on the track 11. In this embodiment, each mounting base 31 is provided with two track 11 wheels. The motor 32 and the two track 11 wheels are connected via a gear 52 transmission mechanism 5, so that the motor 32 drives the two track 11 wheels to rotate, thereby allowing the mounting base 31 to move on the track 11.

[0044] Reference Figure 2-3As shown, a mounting bracket 35 is provided between the two mounting bases 31. The mounting bracket 35 is fixed to the two mounting bases 31, and the scraper 2 is fixed to the mounting bracket 35 via bolts. The motor 32 drives the track 11 to rotate, and the track 11 rotates to move on the track 11, driving the mounting base 31 to move on the track 11, and in turn, driving the scraper 2 in the first direction, thus realizing the function of the drive assembly 3 to drive the scraper 2. Of the two motors 32, one is in operation while the other serves as a backup.

[0045] The side of the receiving tray 4 that is in contact with the side wall of the HIC container is designed according to the shape of the HIC container, so that the receiving tray 4 can receive the mortar scraped off by the scraper 2 and overflowing from the edge of the HIC container.

[0046] Reference Figure 1 and Figure 4 As shown, to achieve the purpose of enabling the receiving tray 4 to move along the first direction on the frame 1, the receiving tray 4 is mounted on the frame 1 via the cooperation of a slide rail 7 and a slider 8. Specifically, the slide rail 7 is arranged along the first direction and fixed to the frame 1, the slider 8 is adapted to and assembled on the slide rail 7, and the receiving tray 4 and the slider 8 are fixed. In this embodiment, two slide rails 7 are provided and spaced apart along the second direction to stably support the receiving tray 4.

[0047] Reference Figure 2 As shown, further, the scraper 2 includes a first position and a second position located between the first station and the second station, the first position is close to the first station, when the scraper 2 moves to the area between the first position and the second position, the scraper 2 and the receiving tray 4 are connected by the transmission mechanism 5, and when the scraper 2 moves to the area outside the first position and the second position, the connection between the scraper 2 and the receiving tray 4 is disconnected, and when the scraper 2 moves from the first position to the second position to the second position, the receiving tray 4 moves to fit the side wall of the HIC container.

[0048] Through this setting, during the working stroke of the scraper 2, the receiving tray 4 is ensured to be able to move to a state of being in contact with the HIC container before the scraper 2 moves to the second station, so as to ensure that the mortar that overflows before the scraper 2 moves to the second station is received by the receiving tray 4, and the mortar is prevented from overflowing to the outer wall of the HIC container. After the receiving tray 4 contacts the HIC container, it is disconnected from the scraper 2, which does not affect the free movement of the scraper 2 between the second position and the second station, so that all the excess mortar can be scraped into the receiving tray 4.

[0049] Reference Figure 1 and Figure 4As shown, to achieve the above purpose, the transmission mechanism 5 includes an active rack 51, a gear 52, and a driven rack 53. The active rack 51 is connected to the scraper 2 and its length direction is parallel to the first direction. The driven rack 53 is connected to the receiving tray 4 and its length direction is parallel to the first direction. The axis of the gear 52 is perpendicular to the first direction and is rotatably connected to the frame 1. The gear 52 is meshed with the driven rack 53. The active rack 51 can move to engage or disengage with the active gear 52 as the scraper 2 moves. When the active rack 51 is engaged with the gear 52, the active rack 51 drives the driven rack 53 to move in the opposite direction through the gear 52. When the scraper 2 moves to the area between the first position and the second position, the active rack 51 remains meshed with the gear 52. When the scraper 2 moves to the area outside the first position and the second position, the active rack 51 disengages from the gear 52.

[0050] Specifically, in this embodiment, the active rack 51 is fixedly connected to the mounting base 31 via a connecting plate, and the driven rack 53 is fixed to the receiving tray 4. The active rack 51 and the driven rack 53 are vertically arranged vertically, and the axis of the gear 52 is parallel to the second direction and is vertically located between the active rack 51 and the driven rack 53. The gear 52 and the driven rack 53 are in meshing state.

[0051] When the scraper 2 moves from the first station to the second station, the active rack 51 and the gear 52 enter into a meshing state when the scraper 2 moves to the first position. When the scraper 2 moves from the first position to the second position, the active rack 51, the gear 52 and the driven rack 53 cooperate to drive the receiving tray 4 to move closer to the HIC container. When the scraper 2 moves to the second position, the receiving tray 4 moves to fit the outer wall of the HIC container, and the active rack 51 and the gear 52 are disengaged. The scraper 2 can continue to move to the second station to scrape off the excess mortar on the top of the mortar in the HIC container and scrape it into the receiving tray 4. Conversely, during the reset stroke of the scraper 2 from the second station to the first station, the receiving tray 4 is driven away from the HIC container to a position farther away from the HIC container.

[0052] To facilitate cleaning of the receiving tray 4, the receiving tray 4 is configured to be movable along the first direction away from the first workstation to disengage from the frame 1, that is, the slider 8 connected to the receiving tray 4 can be moved to disengage from the slide rail 7, so that the staff can remove the receiving tray 4 for cleaning.

[0053] Reference Figure 1-2 As shown, further, a third station is provided on the frame 1, the third station and the first station are spaced apart in the first direction, and the first station is located between the second station and the third station, the scraper 2 can move between the second station and the third station, and the frame 1 is connected to a cleaning mechanism 9 located in the third station, and the cleaning mechanism 9 is used to clean the scraper 2.

[0054] Reference Figure 1-2As shown, the cleaning mechanism 9 includes a cleaning pipeline 91 and a liquid receiving pan 92 connected to the frame 1. The cleaning pipeline 91 is provided with a nozzle 93 for washing the scraper 2. The liquid receiving pan 92 is connected to the frame 1 and is located below the liquid receiving pan 92. The liquid receiving pan 92 is used to receive the sewage after washing the scraper 2. The scraper 2 can be moved to a position between the liquid receiving pan 92 and the cleaning pipeline 91. Specifically, a plurality of nozzles 93 are provided on the cleaning pipeline 91. When the plurality of nozzles 93 are arranged, their washing range covers the entire surface of the scraper 2 to fully wash the scraper 2 and avoid mortar residue. The on and off of the cleaning pipeline 91 is controlled by a solenoid valve to facilitate remote control of the cleaning operation.

[0055] The bottom of the liquid receiving tray 92 is funnel-shaped and is connected to a sewage hose that is connected to an external sewage treatment system.

[0056] Reference Figure 1 As shown, the frame 1 is further provided with a vibration table 10, located between the first and second workstations. The HIC container is intended to be placed on the vibration table 10. Specifically, the vibration table 10 is disposed at the bottom of the frame 1, between the first and second workstations. The vibration table 10 provides a support platform for the HIC container, and allows for grouting and vibratory compaction of the mortar within the HIC container to be performed directly on the vibration table 10. The screeding mechanism also assists in smoothing to improve efficiency. The design ensures that the top of the HIC container is flush with the bottom of the scraper 2 when placed on the vibration table 10.

[0057] The embodiment of the present application can realize remote control of the leveling work after grouting of the HIC container, realize automatic leveling, automatic material connection and automatic cleaning functions, and use as few electrical components as possible to reduce equipment failures caused by radiation during operation.
