A dismantling device for a high-pressure gas storage tank

Abstract

The invention discloses a dismounting device for a high-pressure gas storage tank, and relates to a dismounting tool. The dismounting device for the high-pressure gas storage tank comprises a supporting frame and a lead screw; a connecting hole is formed in the supporting frame; a central through hole is formed in the center of the supporting frame; the lead screw passes through the central through hole; the lead screw is rotatably connected with the supporting frame; a limiting block is fixedly arranged on the lead screw; the limiting block is positioned at the lower end of the central through hole; the upper end of the lead screw is connected with a rotary handle; the lower end of the lead screw is connected with an ejector; the ejector comprises an ejector block and a guide rod fixedly arranged on the supporting frame; the ejector block is in sliding connection with the guide rod; the lead screw passes through the center of the ejector block; and the ejector block is in threaded connection with the lead screw. According to the dismounting device disclosed by the invention, a lining is pushed out from a metal shell through the ejector, so that interference between the supporting frame and the lining can be avoided in a process of separating the metal shell form the lining.

Description

technical field [0001] The invention relates to a dismantling tool, in particular to a dismantling device of a high-pressure gas storage tank. Background technique [0002] Storage tanks are used to store chemical substances such as acids, alkalis, alcohols, gases, and liquids. Usually, gas is stored in metal storage tanks to prevent static electricity during transportation. When gas is stored, it is usually compressed into a liquid state, so the metal tanks used to store it must be able to withstand high pressures and be extremely airtight. The commonly used gas storage tanks are usually made of casting. In order to ensure its airtightness, the casting process is extremely demanding, which makes the cost higher; some other gas storage tanks are made of seamless steel pipes with a thickness of about 1cm and combined sealing. Head welded, because the seamless steel pipe is more expensive, it also fails to reduce its cost. [0003] In order to reduce the cost of the gas stor...
