Description

Technical Field

[0001] The 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 system of nuclear power plants. The dispersed radioactive waste after volume reduction is stored in steel drums and cannot be disposed of directly. It needs to be loaded into 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 for final treatment.

[0003] The flatness of the top of the concrete HIC container must meet the requirements of "High-Integrity Containers for Low and Intermediate Level Radioactive Waste - Concrete Containers" and no water will accumulate. Therefore, after the mortar is poured, the top of the mortar needs to be smoothed and the excess mortar needs to be scraped off to ensure the flatness of the top after the mortar solidifies. Since the waste being treated is radioactive, it is necessary to design a device that can automatically smoothen it instead of manually smoothing it. Summary of the invention

[0012] Preferably, a vibration table is provided on the frame, and the vibration table is located between the first station and the second station, and the HIC container is used to be placed on the vibration table.

[0013] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 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 works. A scraper that can move between the first station and the second station is set, and the top of the mortar in the HIC container is smoothed by the movement of the scraper; a receiving tray is set in the second station to contact the side wall of the HIC container, and the receiving tray receives the excess mortar scraped by the scraper, so as to prevent 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 the 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 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 separated 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 to the receiving tray to drive the receiving tray to move. In the leveling work stroke of the scraper from the first station to the second station, the receiving tray is driven by the transmission mechanism to move to fit with the HIC container to receive the mortar. In the reset stroke of the scraper, the receiving tray is moved to a position away from the HIC container by the transmission mechanism. The transmission mechanism realizes the linkage control of the movement of the scraper and the receiving tray, without the need to move the relay tray manually. The movement of the scraper is driven by the drive assembly, which can be controlled by electric or pneumatic automation equipment, and the personnel only need to clean the receiving tray at a position far away from the HIC container in the second station to avoid contact with the HIC container.

[0014] 2. The transmission structure of the present application realizes the linkage between the movement of the scraper and the movement of the receiving tray. During the working stroke of the scraper, the receiving tray is ensured to move to a state of being in contact with the HIC container before the scraper moves to the second station, so as to ensure that the mortar that overflows in advance before the scraper moves to the second station is received by the receiving tray, and the mortar is prevented from overflowing to 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 as to scrape all the excess mortar 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.

[0015] 3. The present 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, and ensures 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.
