Description

Technical Field

[0001] The invention relates to the technical field of rubber vulcanization equipment, and in particular to an umbrella-type vulcanization equipment for a rubber sealing layer of a gas storage chamber and an application method thereof. Background Art

[0002] In compressed air energy storage projects, underground chambers are often used for gas storage. Therefore, the underground chambers need to be well sealed. At present, the sealing methods for underground chambers include rubber sealing. However, the inner diameter of the underground chamber is large, and multiple rubber seals are required. There are also joint gaps (including longitudinal gaps and circumferential gaps) between two adjacent rubbers. The joint gaps need to be vulcanized to achieve the sealing effect.

[0003] Considering the high temperature (nearly 200℃) and high pressure (not less than 1MPa) of rubber vulcanization, and the need to maintain a certain vulcanization time to complete the entire vulcanization process, the conventional manual scaffolding and handheld vulcanization equipment operation methods have the problems of high construction difficulty, low construction efficiency and high construction risk factor. At present, there are few cases of manual scaffolding construction in the vulcanization of rubber sealing layers for gas storage chambers.

[0004] In addition, when constructing the chamber, most of the chamber entrance area needs to be sealed, often leaving only an artificial passage with a diameter of 1.2m. This means that when vulcanizing the rubber sealing layer, the vulcanizing equipment needs to be disassembled and transported to the chamber through the artificial passage for reassembly and use. The disassembly and assembly process is very troublesome and takes a long time, and the labor intensity required of the workers is also very high.

[0005] In summary, it is necessary to develop an umbrella-type vulcanization equipment and application method for rubber sealing layers for gas storage chambers to solve the problems existing in the prior art of using manual scaffolding and handheld vulcanization equipment, as well as the problem that the existing vulcanization equipment needs to be disassembled and assembled when passing through artificial passages.
