Description

Technical Field

[0001] The utility model relates to the field of disassembly tools, in particular to a disassembly tool for an ultrafiltration membrane shell end cover. Background Art

[0002] Ultrafiltration membrane is a polymer semipermeable membrane used in the ultrafiltration process. Its main function is to separate polymer colloids or suspended particles of a certain size from the solution. The end cap is an important component of the ultrafiltration membrane shell. It and the membrane shell together constitute a closed pressure vessel to ensure the normal operation of the ultrafiltration membrane assembly under working pressure. The first-level desalination water produced by the desalination system of the Xidagou operation area is supplied to users such as steelmaking, chemical industry, and oriented silicon steel, and needs to be filtered using ultrafiltration membranes. After the ultrafiltration device has been running for a period of time, the membrane elements of the equipment are clogged with impurities, causing the membrane elements to become fouled and the water production to decrease. The multiple groups of membrane elements are arranged relatively scattered, with the highest end cap 3.5 meters from the ground. Maintenance personnel standing at high altitudes are prone to falling accidents.

[0003] When disassembling the end cover, first understand the structure of the end cover. Some end covers may be connected to the top of the shell through a threaded barrel. The cover can be separated from the shell by screwing the threaded barrel. Prepare the tools required for disassembly, including wrenches, screwdrivers, and pliers, to disassemble the end cover.

[0004] In the prior art, the end cover is generally disassembled by using a variety of tools. However, when working on a narrow working surface or at a high place, since the connection between the end cover and the membrane element is well sealed and the outer membrane shell is made of ceramic material, disassembling the end cover is not only laborious but also easily causes damage to the membrane element and the membrane shell. The large number of disassembly steps increases the operational risk. Therefore, an ultrafiltration membrane shell end cover disassembly tool is proposed to solve the above problem.
