Material replacement anti-corrosion system for nuclear science

Abstract

The invention discloses a nuclear science material replacement anti-corrosion system which is characterized in that a connecting pipe is slidably mounted in a feeding pipe, a tank cover is mounted at one end of a storage tank through a cover sealing mechanism, a repairing mechanism is arranged in the storage tank, and a fixing block is fixedly mounted on the inner side of the storage tank, so that a rotating rod is rotatably mounted; when the inner side needs to be replaced, a fixing bolt is loosened, limitation on a rotating rod is relieved, the rotating rod is rotated to be removed from a fixing clamping base, accordingly limitation on the position of a T-shaped block is relieved, a pull rod is pulled, the lining is driven to move, then a sliding column is driven to move, a mounting plate drives the T-shaped block to move, and therefore the lining is pulled out of a storage tank. The liner is more convenient to disassemble, convenient to replace and convenient to replace and repair, synchronous replacement of the tank body and the liner during replacement and repair is avoided, the service life of the tank body is prolonged, and coating failure caused by long-time use is avoided.

Description

technical field [0001] The invention relates to the technical field of material replacement and anti-corrosion technology, in particular to a nuclear science material replacement and anti-corrosion system. Background technique [0002] Nuclear science, which is formed by the intersection of natural science and technical science, began in the first half of the 20th century. It is a symbol of the country's scientific and technological level and comprehensive national strength. Nuclear science and technology have always maintained strong vitality. Heavy water is often used in nuclear science. Materials, heavy water needs to be stored in containers, and the containers for storing heavy water need to be treated with anti-corrosion; [0003] However, after long-term use of anti-corrosion containers for storing heavy water on the market, the internal anti-corrosion coating will gradually fail. At this time, the inner lining of the storage tank needs to be replaced and repaired. Th...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a material replacement anti-corrosion system for nuclear science, which can effectively solve the problem that the anti-corrosion container on the market for storing heavy water in the market will gradually lose its internal anti-corrosion coating after being used for a long time in the above background technology. The inner lining of the storage tank is replaced and repaired, and the inner lining of the storage tank and the tank body are usually fixed. When the inner lining is replaced, the tank body and the inner lining need to be replaced synchronously, resulting in unnecessary waste. It is very inconvenient to replace the lining of the storage tank, which affects the supplement of the anti-corrosion coating and is not conducive to the storage of materials
