Leakage point detecting device for clean liner container

Abstract

The invention provides a leakage point detecting device for a clean liner container, which belongs to the technical field of detecting devices for detecting leakage points of the clean liner containers. The clean liner container comprises a cylinder body, a coating and a manhole, wherein the coating is coated at the inner wall of the cylinder body; the manhole is formed on the cylinder body and used for an operator to pass in and out of a cylinder cavity; the leakage point detecting device for the clean liner container is characterized by comprising a resistance meter, a first lead, a second lead and a wet tissue, wherein one pole of the resistance meter is connected with the outer wall of the cylinder body by the first lead; the other pole of the resistance meter is connected with the wet tissue by the second lead; and the wet tissue is in contact with the surface of the coating. The leakage point detecting device for the clean liner container, provided by the invention, has the advantages of simple structure, low requirement on detection conditions, low utilization cost, simplicity in operation, high leakage point identification speed, high accurate rate, no requirement on the surface area of the inner wall of the cylinder body, wide application range and incapability of causing damage to the coating in the operation process, and can be operated only by a common person; and within a short time, all possible leakage points can be found in the liner container.

Description

technical field [0001] The invention belongs to the technical field of detection devices for detecting leaks in clean lined containers, and in particular relates to a leak detection device for high-purity clean lined containers. Background technique [0002] With the continuous increase of demand for electronic chemicals by large and medium-sized enterprises such as electronics, semiconductors, solar energy, and LEDs at home and abroad, electronic chemical manufacturers continue to popularize in China, and the storage requirements for electronic chemicals are also getting higher and higher. As the cycle continues, the local internal leakage of clean lined containers, especially the welded parts of lined containers, will continue to show up. The so-called lined container refers to the coating or coating film on the inner wall of the container. The coating film is used to prevent the contents from corroding the container wall, avoid the dissolution of metal ions, and protect t...

AI Technical Summary

Problems solved by technology

The defects of this detector in the actual operation process are: firstly, it can only detect the container with a large inner surface, the scope of application is narrow, and it takes a long time; secondly, when the leak is small or the leak is along the When the welding rod is turned, the electric spark generated by the discharge is often not seen clearly, so it is easy to cause the leakage detection phenomenon; thirdly, due to the uneven thickness of the coating, when the electric spark detector probe has a high voltage, it is easy to break down Thinly coated parts
